In those, the term Tutsi was equivalent to the phrase \"wealthy noble\"; Hutu meant \"farmer\"; and Twa was used to refer to people skilled in hunting, use of fire, pottery-making, guarding, etc. In contrast to the European conception, rural farmers are often described as wealthy and well-connected. Kings sometimes looked down on them but still formed marriage bonds with them and are frequently described as conferring titles, land, herds, armies, servitors, and ritual functions on them.\n",

However, the social differences between the Hutu and the Tusi have traditionally allowed the Tutsi, with a strong pastoralist tradition, to gain social, economic, and political ascendancy over the Hutu, who were primarily agriculturalists.

2wlfs6 | How did the Thirty Year's War and the Paraguay War lead to such a huge loss of life? | [
{
"answer": "First: a loss of population from pre-war levels is a very different thing than direct counts of casualties. The Holy Roman Empire's population was roughly two-thirds in 1650 of what it was in 1615 (although some regions suffered much more directly), but much of the population loss were simply refugees, loss of territory, and other forms of expatriation.\n\nOf the many who did die, only a relatively small fraction would have died directly from battlefield causes. In the case of the Thirty Years' War, constant disruption to agriculture and commerce resulted in many deaths from famine and disease. This scenario *also* results in a population much less willing to procreate, and substantially increases infant and childhood mortality rates (and maternal mortality, for that matter).\n\nArmies in the pre-modern world were often effectively swarms of locust: even ostensibly friendly armies, like the Lutheran Swedes in Protestant Brandenburg, would inflict grievous harm on whatever region they passed through. Simply supplying these armies could absorb a large quantity of the available food and essentials, before we even talk about looting and pillaging (or incidents like the Sack of Magdeburg, where a victorious army slaughtered ~20,000 townspeople in a single day).\n\nIn short, battlefield deaths in the Thirty Years' War were only a portion of the overall deaths resulting from the war. I expect something similar for the Paraguayan War.\n\nMy main sources are Peter Wilson's recent *Europe's Tragedy: the Thirty Years War* alongside Geoffrey Parker's significantly older *Thirty Years' War*.",

Franciso Solano Lopez's policies essentially conscripted every possible male in Paraguay over the course of the war as the situation grew more and more desperate. There was also the massive displacement of refugees described by u/Aethelric as men fled or even joined the Triple Alliance forces to avoid conscription into certain death in Lopez's army (which, by the end of the war, included many young boys and old men).",

It developed further when he seized Argentine naval vessels moored in the port of Corrientes, north east Argentina. Thereafter López sent two further armies, one to invade the Argentine province of Corrientes along the River Paraná and the other to invade the Brazilian province of Rio Grande do Sul along the River Uruguay. On 1 May 1865 Brazil, Argentina and Uruguay signed the Treaty of the Triple Alliance by which they would not negotiate peace with Paraguay until the government of López had been deposed.\n",

These can lead to a loss of energy in a system and overall loss of products. Along with economic problems, biofilm formation on food poses a health risk to consumers due to the ability to make the food more resistant to disinfectants As a result, from 1996 to 2010 the Center for Disease Control and Prevention estimated 48 million foodborne illnesses per year.

3fv9qu | Would the Lorica Segmentata have been a good choice of armor in medieval times? Could it have retained its effectiveness on the battlefield, let's say, around 1000 AD?" | [
{
"answer": "The threats on the battlefield of 1,000 AD weren't really much different to those of 100 AD; spears and arrows for the most part, with slingshot, battleaxes and swords also being fairly common. Lorica Segmentata offered adequate protection against all of those, so in that sense it was as good as ever.\n\nHowever, Lorica Segmentata *always* had issues competing with chainmail. Even at the height of it's popularity, many romans seem to have favoured chainmail. It's advantages were that it was well suited to mass-production and might have offered superior protection from blunt trauma (although apparently it did worse than mail against dacian falxes). It's downsides were that it was difficult to maintain, generally fit quite badly, had gaps at the armpits and didn't cover the legs at all. \n\nFor the feudal nobles of the early medieval period it would have been distinctly inferior to mail; they didn't mass-produce their armour and often fought on horseback where protection from spears stabbing up into the armpit or sword slashes to their legs was pretty important.",

Although parts of the body were already covered in plate armour as early as 1250, such as the Poleyns for covering the knees and Couters - plates that protected the elbows, the first complete full suit without any textiles was seen around 1410-1430. Components of medieval armour that made up a full suit consisted of a cuirass, a gorget, vambraces, gauntlets, cuisses, greaves, and sabatons held together by internal leather straps. Improved weaponry such as crossbows and the long bow had greatly increased range and power. This made penetration of the chain mail hauberk much easier and more common. By the mid 1400's most plate was worn alone and without the need of a hauberk. Advances in metal working such as the blast furnace and new techniques for carburizing made plate armour nearly impenetrable and the best armour protection available at the time. Although plate armour was fairly heavy, because each suit was custom tailored to the wearer, it was very easy to move around in. A full suit of plate armour was extremely expensive and mostly unattainable for the majority of soldiers. Only very wealthy land owners and nobility could afford it. The quality of plate armour increases as more armour makers became more proficient in metal working. A suit of plate armour became a symbol of social status and the best made were personalized with embellishments and engravings. Plate armour saw continued use in battle until the 17th century.\n",

"answer": "Water can do two things:\n\n- If the device is powered on, short circuits can wreak havoc. The less pure the water, the worse off you'll be (pure water is a very poor conductor).\n\n- If the device is unpowered, water can still cause corrosion and deposit minerals on the circuit boards. The longer it's exposed to moisture, the more corrosion to sensitive components that can occur.",

{
"answer": "Different components react differently to water. Most ICs, for example, will dry just fine, but may end up with residual water stuck underneath the chip, unable to dry. \n\nCapacitors can corrode from the inside out, and transistors do weird things when exposed to water, but immediate drying and cleansing with alcohol will usually prevent that. \n\nNow, the unfixable stuff.\n\nLCD screens are toast in water if water gets between the digitizer and the glass. Also, rechargeable batteries often use alkali or alkaline elements (think lithium ion batteries, among others) that are highly reactive to water. If exposed, very VERY small amounts of water can get into the battery and destroy it, either slowly or immediately. \n\nOther than that, water with any kind of mineral content can short circuit boards and/or leave deposits that hinder the board's ability to function, and can even cause heat build up. Dropping a phone into distilled water, however, won't do much, except cause a physical mess inside the device.

Just as federal policies began to reflect these pedagogical changes, states also began to implement changes to reflect the same values. In 1998, California passed an initiative that almost all classroom instruction should be in English. These changes were due mainly in response to federal English-only standardized testing.

"text": "Education reform is a topic that is in the mainstream currently in the United States. Over the past 30 years, policy makers have made a steady increase at the state and federal levels of government in their involvement of US schools. US states spend most of their budgets funding schools, whereas only a small portion of the federal budget is allocated to education. Although states hold the constitutional right on education policy, the federal government is advancing their role by building on state and local education policies. Education Reform is currently being seen as a \"tangled web\" due to the nature of education authority. There are several authorities looking over education and what can and cannot be implemented. Some education policies/reforms are being defined at either the federal, state or local level and in most cases, their focuses/authority overlap one another. This form of authority have led many to believe there is an inefficiency within education governance. Compared to other OCED countries, educational governance in the US is more decentralized and most of its autonomy is found within the state and district levels. The reason for this is that US citizens put an emphasis on individual rights and have a suspicion on government. A recent report by the National Center on Education and the Economy, believes that the education system is neither coherent nor likely to see improvements due to the nature of it.\n",

But state laws vary, as do their definitions of banks, narrow banks, money services businesses, and money transmitters. Although PayPal is not classified as a bank, the company is subject to some of the rules and regulations governing the financial industry including Regulation E consumer protections and the USA PATRIOT Act. The most analogous regulatory source of law for PayPal transactions comes from peer-to-peer (P2P) payments using credit and debit cards. Ordinarily, a credit card transaction, specifically the relationship between the issuing bank and the cardholder, is governed by the Truth in Lending Act (TILA) 15 U.S.C. §§ 1601-1667f as implemented by Regulation Z, 12 C.F.R. 226, (TILA/Z). TILA/Z requires specific procedures for billing errors, dispute resolution, and limits cardholder liability for unauthorized charges. Similarly, the legal relationship between a debit cardholder and the issuing bank is regulated by the Electronic Funds Transfer Act (EFTA) 15 U.S.C. §§ 1693-1693r, as implemented by Regulation E, 12 C.F.R. 205, (EFTA/E). EFTA/E is directed at consumer protection and provides strict error resolution procedures. However, because PayPal is a \"payment intermediary\" and not otherwise regulated directly, TILA/Z and EFTA/E do not operate exactly as written once the credit/debit card transaction occurs via PayPal. Basically, unless a PayPal transaction is funded with a credit card, the consumer has no recourse in the event of fraud by the seller.\n",

2wjkof | why does audio feedback always sound like a high squealing noice? | [
{
"answer": "Resonance. Audio equipment (and most physical objects) will have special vibration frequencies that are amplified much more than others. Normally, even if the microphone picks up the speaker sound, the feedback decays away like an echo because it’s not at a resonant frequency or the feedback is ‘out of phase’. But if a sound (including random noise) occurs at a resonant frequency and is ‘in-phase’ then the output exactly matches the input and a ‘positive feedback loop’ occurs: these frequencies keep growing each time they pass through the system, until they saturate the equipment at its limits. You can notch out these frequencies, and then only non-resonant/out-of-phase frequencies remain and the audible ‘feedback effect’ doesn’t occur. (Also: as you probably know, moving things around also reduces the changes of feedback occurring, for simple reasons like preventing the microphones from picking up the sounds or because the resonant frequencies are out of phase, but since resonance can change with variations like temperature, accidents still happen.)",
"provenance": null
},
{
"answer": "There are 2 things happening here. In a feedback loop, the microphone is picking up some of the amplified sound (because it \"hears\" it from the speaker) and sends it back around. This is why it gets very loud, very fast. The high-pitched squeal happens for a different reason. If the microphone and the speaker are at a certain distance and orientation with each other, such that the sound coming out of the speaker hits the microphone at a certain point in time, certain parts of the sound are amplified slightly differently. Microphones, amplifiers and speakers are not perfect...they work better with some frequencies better than others. If the alignment is such that a certain \"high sound\" gets amplified better than the other sounds, this results in the squeal you hear. \n\nThis looping happens very fast, which is why the sound starts a fairly low volume and pitch, then gets very loud and high pitched. \n\nIf all microphones, amplifiers and speakers (and room acoustics!) were perfect, this would not happen.\n\nFor you techies: One trick that used to be used before modern DSPs (digital signal processors) was to place 2 microphones at every performer. One mic was actually used by the performer, while a second mic was a few inches away, but connect 180 degrees out-of-phase (\"reverse the wires\"). The performer's mic would capture both the performer's voice AND whatever else (instruments, crowd, etc) was near by. The second mic had the same, but no vocal. Since it was 180 out of phase, you could add this to the other mic (with a special amp...) and almost perfectly cancel out everything but the vocal. A pain in the ass to set up, but you could get some great sound that way.\n\nEdit: Added some cool microphone info\n",
"provenance": null
},
{
"answer": "~~The pitch is determined by the length of time it takes for the sound to make a lap from the microphone, through the mixer, processors and amplifiers, come out of the speaker, and reach the microphone again. If you take and lengthen that time, say, by moving the mic and speaker farther away, but such that the mic still hears the speaker, then the pitch will lower. Move it closer and it will rise.~~\n\n~~The pitch itself will be the inverse of a multiple of that round-trip time, so, for instance, if it takes 1/20,000 of a second to make the trip, the whistle might happen at 20 kHz, 10 kHz, 6.67 kHz, 5 kHz, 4 kHz, etc. Which one depends on other factors that might affect the resonance.~~\n\nWhen you do have a feedback problem, you can do various things to weaken or break the loop, from the acoustic step of making sure the mic doesn't hear the speaker (this is the ideal solution), to using an equalizer to \"notch out\" the frequency range where the feedback is happening, to adding a delay so that it ends up being an echo instead of a whine, to (my new-found favourite) using a pitch-shifter to bend the pitch upward or downward just a couple of cents.\n\nEdit: /u/bandaged pointed out some errors in my understanding.",

3lfrem | What happened to pre-Columbian dog breeds? Did they die off from diseases brought by European dogs? | [

"answer": "There are several breeds of domestic dogs that were developed in North America. Some are breeds are still around, while others are extinct.\n\nAmong those that are still popular pets today you can find huskies and Malamute and their relatives, which have Old World counterparts in the Eurasian Arctic as well. Chihuahuas trace their origins to the other end of the continent in Mesoamerica, as does the Xolo (aka the Mexican Hairless Dog, although there are variants with hair).\n\nAnother breed that's still around, but is rarely seen as a pet, is the Carolina Dog. These dogs resemble dingos, as a lot of dogs will after being feral for many generations. They were rediscovered relatively recently in the 1970s and we're not sure how long they've been around. Dogs like them show up in pre-Columbian art, but they were pets back then or if they were already feral is unknown. \n\nMany of the most famous extinct breeds are from the northwestern part of North America. For example, there are the [Hare Indian Dog](_URL_0_), the [Tahltan Bear Dog](_URL_2_), and most famously, the [Salish Wool Dog](_URL_4_). The first two were bred for different styles of hunting, while the wool dogs, as their name suggests, were breed for wool.\n\n**Sources**\n\n* [Pre-Columbian origins of Native American dog breeds, with only limited replacement by European dogs, confirmed by mtDNA analysis](_URL_1_)\n* [Dogs of the American Aborigines](_URL_3_)",

Lack of written records makes it hard to know if the modern breed is the same as the one that existed 4000 years ago. They're threatened by extinction due to disease and no longer being as useful in the day of the snowmobile.",
"provenance": null
},
{
"answer": "The Native Americans of the North did indeed keep dogs, but they were not specifically of any breed as we would understand it. They were what's called a landrace, which means that they all looked similar enough that they could be considered one 'type' of dog, but the common traits that they shared were the result of a more natural selection process than intentional breeding.\n\nTo begin with, since these dogs would likely have been semi-feral camp dogs, fed on scraps and left to roam around near the settlement, traits such as friendliness (friendlier dogs get more food, attention, etc.) would have been useful to them, along with traits that enabled them to better survive in their native environment, since they would likely be spending most, if not all, of their time exposed to the elements.\n\nOne thing to note, which I shall only go into briefly, is that genes for certain character traits can go hand in hand with [physical characteristics](_URL_4_), which explains how a landrace might come about of dogs that all looked pretty similar - since the traits that made them successful among humans could also make them look a specific way.\n\n People subsequently realised that they could use dogs to perform certain tasks and no doubt began to pair two good dogs, who seemed to perform the tasks well, together to create more good dogs. This does not constitute an effort to create a 'breed' as we understand it today, but no doubt helped propagate the beneficial traits through the canine population.\n\nA good example of this is that before the Spanish Conquest, there were no native wild horses in North or South America. Before they had horses, plains tribes utilised dogs to carry their belongings and pull the tipi poles and coverings when they were on the move. (Interestingly, for this reason the introduction of horses meant that the tipi poles could be longer and heavier, which meant the tipi design became bigger). Thus dogs with traits that benefitted them in these areas (strength, endurance, good temper) were preferred and kept around (i.e. not killed), and passed on the beneficial genes.\n\nThis resulted, over a long period of time, in a homogenised 'breed' of dog developing without any real conscious effort to create one.\n\nThese dogs still exist, though have now become a standardised breed - called American Indian Dog or [Carolina dog](_URL_1_).\n\nOriginally you would probably have found that native dogs would have varied depending on locality. All the dogs from one settlement or area would probably have looked very similar, as they were all interbreeding, but the dogs from another tribe or from other parts of the country would have had a slightly different set of traits that better suited their particular climate and the lifestyle of the tribe to which they belonged. A good example of this is dogs bred by the Inuits ([Malamute](_URL_2_), [Canadian Eskimo dog] (_URL_0_)). They had to be able to perform well in cold weather, as well as pull sleds. So they are very strong, energetic, long legged and thick furred) The Canadian Eskimo dog was also used for hunting seals and other arctic game. They were not considered pets, nor as part of the natural world - they were tools to assist survival.\n\nExamples of native dogs from South America are the [Peruvian Hairless Dog](_URL_5_) and the [Xoloitzcuintle](_URL_3_). It is theorised that their hairlessness was a spontaneous mutation of the American Indian dog that allowed them to better cope with the tropical conditions. As well as hunting, these dogs were often raised for meat.\n\nAfter the Europeans arrived, they brought dogs of their own, which would no doubt have interbred with the local dogs and added a bit of variation to the gene pool. But the native dogs, which had over many generations become perfectly adapted to their locality, did not die out. They excelled in the tasks they were put to. The Europeans saw the advantage of malamutes, etc. over european dogs when it came to pulling sleds in the snow and made good use of them. And Native Americans often traded good hunting/sled dogs for other tools. It is possible that european dogs brought european dog diseases, but I can't imagine it would be something that was well documented.\n\nI hope this answers your question. Sorry it's a bit long... brevity does not come naturally to me.",

9tqgr7 | How was Irish culture change by the settling of Vikings? | [
{
"answer": "It's well attested to that raiders and settlers from Scandinavia had a substantial impact on Irish society. In some instances we can still be point to this influence in contemporary Ireland.\n\nFirst, a brief history of Viking contact with Ireland. The first recorded reference is from 795, when it was reported that they raided a monastery on Rathlin Island (just three years after the famous raid at Lindisfarne, England). At this time Irish craftwork was among the most prized in Europe, so plundering these largely undefended monastic settlements (centres of wealth in rural Ireland) must have been extremely rewarding for the raiders.\n\nFor the following few decades the Norsemen continued to perform hit-and-run raids on Ireland, until around 840, when it was reported that Viking raiders were wintering in Ireland. Around 900 the Norse warriors were beginning to settle permanently on the island. Throughout the 10th century their influence were constant features of the many Irish kingdoms’ warring, often acting as mercenaries for the Gaelic kings, if not in their own right. Their influence as political actors began to falter from around the end of the 9th century (famously at the Battle of Tara (980) and the Battle of Clontarf (1014)). Like what would happen to later Anglo-Norman settlers, the Norse settlers largely became Gaelicized, becoming integrated into Irish society, likely within just a few generations of settlement.\n\n1. **Urbanisation**\n\nAlthough this is hotly contested in early medieval Irish historiography, the Vikings are largely credited with bringing urban settlement to Ireland. Likely some proto-urban settlement existed, known by historians as the “monastic town”, but by our own definition of town (or even that of a medieval German or French person) this argument does not hold water, and they were still largely agrarian. From the early 10th century the Vikings established settlements that remain to this today Ireland’s primary urban centres – Dublin, Wexford, Waterford, Cork, and Limerick all being set up by Norse settlers during this period.\n\n2) **Language**\n\nModern Irish is still littered with words and phrases that can clearly be recognised as coming from Norse. A few examples: Gaelic words for garden (gairdín), shoe (bróg), river (abhainn), boat (bád), and market (margad) all suggest Norse origin. This also provides another insight into what influence these settlers might have had on Irish society – likely concepts such as ‘a garden’ (as in an enclosed area) or ‘a market’ where not words which were needed by the Gaelic Irish before the Norse brought them.\n\n3) **Place-names**\n\nAnother linguistic insight into Norse influence on Irish society can be drawn from place-names. For many towns or settlements, the only evidence historians have for Norse influence is the name. For example, Leixlip, Co. Kildare is drawn from ‘lax hlaup’, Old Norse for ‘salmon leap’. A town such as Wicklow also likely has Viking influence, as the ‘wick’ comes from the same Norse word that the ‘vik’ in Viking does, referring to a bay or inlet. It’s the same root that English towns, such as Norwich, come from.\n\n4) **Craftwork**\n\nAlthough I know not so much about this, the archaeological evidence suggests a merging of Norse and Irish styles of craftwork.\n\n5) **Trade network**\n\nThe Vikings established a trading network that extends across an enormous portion of Eurasia, and even into Africa and North America. Viking trade set Ireland among this network and fixed the island into an international commercial world. One of the most incredible examples of this is an 8th century coin from Iraq being found during an excavation of a small Hiberno-Norse settlement in the south-east of Ireland.\n\n & #x200B;\n\nThis list is by no means exhaustive. If anyone has any questions I will certainly elaborate on the evidence for what I’ve said. Some historians I would recommend for you check out if you would like to find out more would be Howard Clarke, John Bradley, and Colman Etchingham.\n\n & #x200B;\n\n[_URL_0_](_URL_0_) This website should also provide some interesting information if you're interested in the urban aspect of Viking influence.",

The Vikings left little impact on Ireland other than towns and certain words added to the Irish language, but many Irish taken as slaves inter-married with the Scandinavians, hence forming a close link with the Icelandic people. In the Icelandic \"Laxdœla saga\", for example, \"even slaves are highborn, descended from the kings of Ireland.\" The first name of Njáll Þorgeirsson, the chief protagonist of \"Njáls saga\", is a variation of the Irish name Neil.

Many of Ireland's towns were founded at this time as Viking trading posts and coinage made its first appearance. Viking penetration was limited and concentrated along coasts and rivers, and ceased to be a major threat to Gaelic culture after the Battle of Clontarf in 1014. The Norman invasion in 1169 resulted again in a partial conquest of the island and marked the beginning of more than 800 years of English political and military involvement in Ireland. Initially successful, Norman gains were rolled back over succeeding centuries as a Gaelic resurgence reestablished Gaelic cultural preeminence over most of the country, apart from the walled towns and the area around Dublin known as The Pale.\n",

21fyt0 | As the first European city founded in California, why didn't San Diego become as prominent as San Francisco or Los Angeles? | [
{
"answer": "Without answering your question precisely, I'd like to point out that being the first city doesn't always make it important. For example, Jamestown, though the first English colony in America, no longer even exists even though it was the capital for 80 or so years. \n\nTerrain and resources make a larger impact on the success of a colony. Oil was also found in Los Angeles leading a a growth boom in the 19th century. Sand Diego appears to have suffered population-wise as well when it was part of Mexico, not sure if that's because of political reasons, but it happened.\n\nI'll link these two sources which corroborate what I say, but I'm not saying I'm wrong. I found them after a quick Google search so I hope they're decent.\n\n[Oil in LA,](_URL_1_) and [decline in San Diego.](_URL_0_)",
"provenance": null
},
{
"answer": "\"City\" is a very generous term prior to 1849 for San Diego, Los Angeles, Yerba Buena (aka San Francisco) or any other community in what is now California. They were communities based around Spanish missions, but hardly cities. Under Spanish and Mexican rule, Alta California was a rural backwater carved into large \"Ranchos\", whose landowners sought to pattern themselves after Spain's landed gentry.\n\nAfter the US won control of California in 1848, there was the famous discovery of gold in Northern California, leading to the Gold Rush and the extremely rapid growth of San Francisco. Southern California was far away from the gold fields and saw limited growth, while San Francisco, with its massive natural bay and huge influx of immigrants, was the catalyst for California statehood.\n\nIn 1876 the Central Pacific railroad was built to connect Northern California with Southern California. Los Angeles, as opposed to San Diego, was chosen as the southern terminus of the railroad, and this gave Los Angeles a head start over San Diego in terms of growth. The discovery of oil in Los Angeles in 1892 led to more financial wealth for the city, and by that time the ball was rolling for Los Angeles to eventually become a major city.\n\nSan Diego, on the other hand, was left out of most of these developments. Largely agricultural and rural, it wasn't until World War II that San Diego experienced major, sustained growth. San Diego became a major Naval base for the war against Japan, and is to this day the largest US Navy base in the Pacific. During the war and in the decades after, it was a major defense manufacturing city, and grew to be the second largest city in California, after Los Angeles.\n\nFor sources, this is basically what every 4th grader in California learns. For more depth and understanding, I would look to something like Kevin Starr's California: A History",

{
"answer": "Los Angeles had the oil boom and then Hollywood and then everything. (In the early 1920s perhaps 1/4 of the world's oil was coming from areas around LA.) San Francisco had the gold rush and shipping (the bay is one of the best natural bays in the world). Both had the central valley agricultural boom as well. Los Angeles additionally benefits from a very large area of fairly flat land which is perfect for development.\n\nSan Diego may have been founded earlier but development requires impetus. For SF and LA there were enormously strong early development cycles in the mid 19th and early 20th centuries which caused the cities to grow large enough to where they could fuel their own growth. San Diego didn't have the same advantages to the same degree so it grew slower.",

Next, the two cities battled over becoming the port destination for import and export; L.A. won this battle, as well.

Without the original memory to give them context, these remembered events might prompt the subjects to see themselves as emotional or irrational people. In the United States, the President's Council on Bioethics devoted a chapter in its October 2003 report \"Beyond Therapy\" to the issue.

Instead of dealing with the truth of the situation a new altered reality is created where the memory is dissociated from pain, or the memory is forgotten altogether. Another issue that arises is exposing patients to unnecessary risk. Traumatic experiences do not necessarily produce a long term traumatic memory, some individuals learn to cope and integrate their experience and it stops affecting their lives quite quickly. If drug treatments are administered when not needed, as when a person could learn to cope without drugs, they may be exposed to side effects and other risks without cause. Loss of painful memories may actually end up causing more harm in some cases. Painful, frightening or even traumatic memories can serve to teach a person to avoid certain situations or experiences. By erasing those memories their adaptive function, to warn and protect individuals may be lost. Another possible result of this technology is a lack of tolerance. If the suffering induced by traumatic events were removable, people may become less sympathetic to that suffering, and put more social pressure on others to erase the memories.\n",

{
"answer": "I recommend you go to his own autobiography to look at how his belief in universal human rights evolved over time, after being raised in two cultures that were perfectly happy with a rigid ethnic hierarchy. It turns out neither Gandhi, nor any of my own Catholic saints were born fully adult and fully mature.\n\nExamples - He first became politically active and well-known while working as a lawyer in (British) South Africa. His early campaigns focused on bringing upper caste Indians to something like parity with the English. He burned little of his scarce political capital on native Africans or lower caste \"coolies,\" at first. This evolution was only hinted at in the movie.\n\nCritics may also go after his difficult relationship with his son Harilal Gandhi. It is above my paygrade to speculate on whose fault it was that his life unraveled as it did, but others may not hold back.\n\nHe also spends many pages of his autobiography discussing some medical quackery that he experimented with - not so much a moral failing, but fodder for pundits and cranks on the internet.

{
"answer": "The problem here is that there is a vast disjuncture between Gandhi the historical figures versus the popular mythology that has built around him. The 1982 biopic is a reflection of this latter aspect of Gandhi's image. The film presents Gandhi and his world in starkly Manichean of light versus dark. Note that Kingsley's performance (almost universally praised among critics) is one that highlights Gandhi's stoic and moral gravitas and thus accentuates this duality. Many of the other historical characters in the film shrink compared to him.\n\nThe reality is that the historical Gandhi inhabited a highly complex political world in which often belies reducing it to simple terms like good vs. evil or justice vs. injustice. That Gandhi inhabited and operated in such a world is not even an open secret, but the strength of his mythologized public image means that the act of uncovering the historical record carries far more weight to them than less valorized historical figures. For example, there have been recent publications of Nixon audio tapes that highlight his various racial, sexual, and political prejudices, often expressed in language the mods here would require a NSFW tag for, yet these revelations are somehow not as alarming as Gandhi using a formal greeting of \"dear Friend\" in a letter to Hitler (which the critic in the OP's first link finds appalling). \n\nJewaharlal Nehru actually advised ~~David~~ Richard Attenborough not to deify Gandhi, as \"that is what we have done in India and he was to great a man to be deified.\" Although Attenborough claimed to follow Nehru's advice, *Gandhi* has fallen into the trap of many biopics by oversimplifying its subject and the context of the times. \n\n*Source*\n\nCarnes, Mark C. *Past Imperfect: History According to the Movies*.

Paying reparations is a classic punishment of war but in this instance it was the \"extreme immoderation\" that caused German resentment. Germany made its last World War I reparation payment on 3 October 2010, ninety-two years after the end of World War I. Germany also fell behind in their coal payments. They fell behind because of a passive resistance movement against the French. In response, the French invaded the Ruhr, the region filled with German coal, and occupied it. At this point the majority of Germans were enraged with the French and placed the blame for their humiliation on the Weimar Republic. Adolf Hitler, a leader of the Nazi Party, attempted a coup d'état against the republic to establish a Greater German Reich known as the Beer Hall Putsch in 1923. Although this failed, Hitler gained recognition as a national hero amongst the German population. The demilitarized Rhineland and additional cutbacks on military infuriated the Germans. Although it is logical that France would want the Rhineland to be a neutral zone, the fact that France had the power to make that desire happen merely added onto the resentment of the Germans against the French. In addition, the Treaty of Versailles dissolved the German general staff and possession of navy ships, aircraft, poison gas, tanks, and heavy artillery was made illegal. The humiliation of being bossed around by the victor countries, especially France, and being stripped of their prized military made the Germans resent the Weimar Republic and idolize anyone who stood up to it.\n",

An indication of individual proficiency and a basis of test is considered the ability to make a continuous foot march of twenty-five (25) miles in eight (8) hours, a five (5) mile march in one (1) hour and a nine (9) mile march in two (2) hours, with full equipment.\n\n > Men will be mentally and physically conditioned for battlefield environment by obstacle courses that overtax endurance as well as muscular and mental reactions, by passage of wire obstacles so situated as to permit overhead fire, by a night fighting course with sound only as an indication of danger, and a street fighting course with booby traps and sudden appearing targets. Live ammunition will be employed in all three tests.\n\n**Unit Training**\n\n > By the end of the 9th week of unit training infantry battalions will be able to function efficiently, by day or night, independently or reinforced.\n\n > Field Artillery training will, in general, follow \"Unit Training Program for Field Artillery (Modified for Airborne Field Artillery)\". Stress will be placed on decentralization within batteries to the end that self-contained gun sections will be capable of delivering prompt fire, using both direct and indirect laying with hastily computed firing data in the early stages of any action. Trainlng will also include the operation of batterles, battalions, and division artillery as units in order that the artillery can be capable of massing its fire.\n\n > The unit training phase of infantry battalions will include tactical exercises in which the battalion is supported by a battery of field artillery.\n\n > Division engineers will be trained primarily in engineer combat duties. See inclosure a. (Clearance and repair of airdromes or landing strips will be performed by aviation engineers.)\n\n > Medical units will be trained for normal functions in ground operations and also will be trained in evacuation by air.\n\n > Quartermaster units will be trained in all phases of ground and aerial supply, to include local defense of supply installations.\n\n > Ordnance units will be trained to repair standard ordnance and known enemy weapons and vehicles.\n\n > Antiaircraft elements: (See Inclosure No. 2)\n\n > Signal units will be trained to operate all communications equipment issued to the division emphasizing the capability of all personnel to operate all equipment.\n\n > All units will be prepared to either enter combat immediately on landing or to move promptly by marching against an objective.\n\n > During unit training, combat firing exercises, emphasizing infiltration tactics, rapid advance, and continuous fire support will be planned to conclude each phase.\n\n > Battalion tactical exercises, whenever possible, will include training in air-ground liaison, proper and prompt requests for air support, and air to ground recognition training for aerial supply.\n\n > Unit training will be concluded by tactical exercises including separate glider and parachute regiments, artillery and engineer battalions, and divisional special units (company).\n\n**Combined Training**\n\n > Regimental combat team and divisional tactical exercises will be held during this period. Tactical situations which require the complete staff planning of an airborne attack will be the background of each problem, but the paramount importance of the ground operation will be impressed on staffs and troops. All problems to be solved will envision, or will actually require, the presence of appropriate troop carrier and air support units.\n\nMen could only be assigned to the parachute troops at their own request. On 25 May 1942, the Secretary of War directed that infantry replacement training centers each provide 105 men per week to the Airborne Command who were medically qualified for parachute training. The standards prescribed were very strict;\n\n > Qualifications set forth were those standardized as a result of innumerable medical reports and examinations. The volunteer must be alert, active, supple, with firm muscles and sound limbs, capable of development into an aggressive individual fighter, with great endurance. Age requirements were: Majors not over forty years of age; captains and lieutenants, not over thirty-two; and enlisted men, eighteen to thirty-two, inclusive. Medium weight was desired, maximum not to exceed 185 pounds; height, not to exceed seventy-two inches; vision, maximum visual acuity of twenty-forty, each eye; blood pressure, persistent systolic pressure of 140MM, or persistent diastolic pressure about 100MM to disqualify. Also on the disqualification list were recent venereal disease, evidence of highly nervous system, lack of normal mobility in every joint, poor or unequally developed musculature, poor coordination, lack of at least average athletic ability, history of painful arches, recurrent knee and ankle injuries, recent fractures, old fractures with deformity, pain or limitation of motion, recurrent dislocations, recent severe illness, operation, or chronic disease.\n\nMen could be accepted at any time from arrival at a replacement training center to the completion of 13 weeks of individual training. On 10 June 1942, the weekly quota for volunteers from each replacement training center was revised upward to 125; this quota could be exceeded each week, under the provision that a replacement training center would provide less than 500 candidates each month. On 15 June 1942, men were only to be accepted after they had completed at least 8 weeks of individual training. In early 1943, the Airborne Command began to gear up to train larger numbers of loss replacements as the first airborne units entered combat. Men thus assigned to the Parachute School at Fort Benning or, after 9 April 1942, Fort Bragg, completed 13 (later 14, and then 17) weeks of individual and specialty training with an emphasis on placement in a parachute unit, and an additional 5-week course ensuring that the recruits had completed the training regimen to the best of their ability, had qualified on their assigned weapon(s), had completed a transition firing and battle indoctrination course, and had completed a squad tactical jump. If recruits were not called for shipment in a prompt manner, an additional 4-week small-unit tactics course was to be taught; when interrupted by a call for shipment, men were to be taken from the training unit farthest along in these activities.\n\n**Source:**\n\nEllis, John T. *The Army Ground Forces: The Airborne Command and Center, Study No. 25*.

During this period, the activities of the division primarily involved airborne training, as well as taking part in several training exercises. However, while airborne training for the first four American airborne divisions was conducted during 1943, the 13th encountered considerable difficulties when it came to its turn for training. By the last few months of 1943 the 82nd and 101st Airborne Divisions had conducted airborne exercises and finished their training, and had then been transferred to Europe; to ensure the divisions could conduct airborne operations, a majority of the transport aircraft available in the United States had been sent with them, and even more were transferred to Europe as replacements after the American airborne landings in Normandy in June 1944. Consequently, very few transport aircraft were available for use by the 13th, and the original training exercise for the division that had been scheduled for June 1944 had to be postponed until 17 September, and then once again until 24 September.\n",

The term derives from the idea of a \"bend\" (cf. a \"kink\") in one's sexual behaviour, to contrast such behaviour with \"straight\" or \"vanilla\" sexual mores and proclivities. It is thus a colloquial term for non-normative sexual behaviour. The term \"kink\" has been claimed by some who practice sexual fetishism as a term or synonym for their practices, indicating a range of sexual and sexualistic practices from playful to sexual objectification and certain paraphilias. In the 21st century the term \"kink\", along with expressions like BDSM, leather and fetish, has become more commonly used than the term paraphilia. Some universities also feature student organizations focused on kink, within the context of wider LGBTI concerns. Psychologist Margie Nichols describes kink as one of the \"variations that make up the 'Q' in LGBTQ\".\n",

These include erotic asphyxiation and self-bondage.

{
"answer": "Most music is repetitive to some extent (verses following a certain melody, then maybe a chorus, then perhaps start over at the melody for verses). Very seldom does music, especially in modern compositions, progress with no pattern.\n\nSo the soundtrack will consist of one clip of music--could be 5 seconds, could be 30 seconds, could be several minutes, whatever. And it will be set on a loop that doesn't so much say \"loop these two points\" but rather, \"when the music clip is over, play the clip again,\" so it instantly starts back.

Also, covalent inhibitors such as beta lactam antibiotics which contain weak electrophiles can lead to idiosyncratic toxicities (IDT) in some patients. It has been noted that many approved covalent inhibitors have been used safely for decades with no observed idiosyncratic toxicity. Also, that IDTs are not limited to proteins with a covalent mechanism of action. A recent analysis has noted that the risk of idiosyncratic toxicities may be mitigated through lower doses of administered drug. Doses of less than 10 mg per day rarely lead to IDT irrespective of the drug mechanism.\n",

6dsvle | Before Israelite conquered it, who ruled Jericho and where is Jericho mentioned outside the bible? | [
{
"answer": "This is a good question, but I want to start by clearing up a couple of things. Firstly, some definitions: 'Canaan' is usually used to refer to the area from the Eastern Mediterranean coast to the hill country that's farther inland, and often comes with an implied sense of 'not Israel and Judah'. I'll use it here to mean everything in between Egypt and the Hittites.^1 The only significant collection of contemporary texts we have for this area are from the city state of Ugarit (now Ras Shamra, in the north-west of modern-day Syria). There are some inscriptions from the various Phoenician cities and a couple from the kingdom of Damascus, but evidence is very, very scarce. \n\nSecondly, the conquest of Canaan as described in the Bible has practically no evidence to support it and is probably a complete invention.^2 Major problems with the biblical account were first raised when the archaeological record from a large number of sites around the area didn't seem to add up to what we had been expecting to find: contemporary destruction layers in the Late Bronze Age (around 1100 BCE or so, when the story is set), and an abrupt change in artefact styles (pottery, architecture, jewellery) and cultural practice (burial style, traces of rituals, diet). None of these were there, and in fact what we did find was continuity between Late Bronze Age and Early Iron Age. In other words, the native population probably wasn't replaced with two million or so Israelites coming from Egypt.\n\nThirdly, Jericho is actually one of our most important case studies when it comes to understanding the history of Israel in Canaan. The really big excavation of the city (focusing on Neolithic and Early Bronze Age Jericho, but including a broad survey of the entire chronology of the site) conducted by Kathleen Kenyon in the 1950s found some pretty remarkable things.^3 To summarise, she discovered that the city had had significant fortifications in the Middle Bronze Age (roughly up to 1550 BCE), but that these had been destroyed completely during that time. Of course, this is much too early for anything remotely related to a political entity 'Israel'^4 to be relevant; even the most conservative scholars date the reign of David^5 to the late-11th or early-10th century BCE. Jericho was only a minor settlement during the Late Bronze Age and Early Iron Age, and was even mostly abandoned for several centuries during this period. It wasn't until the 9th century BCE that Jericho was properly rebuilt.\n\nNow, to actually get to your question: who ruled Jericho before it was destroyed? Whoever it was, they didn't really leave us much to work with. According Kenyon's interpretation of the evidence, Jericho became a city of some importance - and perhaps with some degree of independence - like many other major Middle Bronze Age sites (including Ugarit) in the first half of the second millennium BCE. Their cemetery was extensive, and the elaborate nature of the burials there suggests that the rulers of the city were relatively well-off. We know from Egyptian scarabs found at the site that they traded with the Egyptians. Kenyon didn't find much in terms of religious worship, but geographically speaking it is likely that they shared the general Canaanite pantheon with the other cities in the region (Ba'al-Hadad, El, Anath, and Astarte being their most important deities). \n\nI am not aware of the city being mentioned in any extra-biblical texts (neither from Egypt nor from Mesopotamia), but I am happy to be corrected if anyone else has an example.\n\nI hope this helps! Please let me know if I can expand on or clarify anything!\n\n-----------\n\n^1 Scholars are usually pretty inaccurate with the term, so depending on preference some will include or exclude the Phoenician city states; some even only use 'Canaan' to refer exclusively to the area that would become the territory of the kingdoms of Judah and Israel.\n\n^2 see Davies, *In Search of 'Ancient Israel'*; Finkelstein and Silberman, *The Bible Unearthed*; also Dever, *What did the biblical authors know and when did they know it?* (a little outdated now, but still a good, neutral survey).\n\n^3 See Kenyon, *Excavations at Jericho*, several volumes spanning the periods 1954-1958 and 1960-1983.\n\n^4 The Merneptah Stele, dating to the 13th century BCE, refers to something resembling Israel, but it should be seen as a name for the area rather than a political entity.\n\n^5 David's historicity is a can of worms I really don't want to open here, but even assuming he existed and ruled over a united kingdom he's a good four centuries too late.",

This is based on . During a series of excavations from 1930 to 1936 John Garstang found a destruction layer at Jericho corresponding to the termination of City IV which he identified with the biblical story of Joshua and dated to c. 1400 BC. It was therefore a shock when Kathleen Kenyon in the 1950s, using more scientific methods than had been available to Garstang, redated Jericho City IV to 1550 BC and found no signs of any habitation at all for the period around 1400 BC. Wood's 1990 reversion of City IV to Garstang's original 1400 BC therefore attracted considerable attention. In 1999, based on a reanalysis of pottery shards (a method which can provide highly accurate dates in the context of the ancient Near East), Wood argued that Jericho could have been captured in the Late Bronze Age by Joshua. Wood and Piotr Bienkowski debated this in the March/April 1990 issue of Biblical Archaeological Review, with Bienkowski writing:\n",

The disaster claimed the lives of an estimated 1,000 to 2,000 Russian soldiers, mostly barely trained and disoriented conscripts; the heaviest losses were inflicted on the 131st 'Maikop' Motor Rifle Brigade, which was completely destroyed in the fighting near the central railway station. Despite the early Chechen defeat of the New Year's assault and the many further casualties that the Russians had sustained, Grozny was eventually conquered by Russian forces amidst bitter urban warfare. After armored assaults failed, the Russian military set out to take the city using air power and artillery. At the same time, the Russian military accused the Chechen fighters of using civilians as human shields by preventing them from leaving the capital as it came under continued bombardment. On 7 January 1995, Russian Major-General Viktor Vorobyov was killed by mortar fire, becoming the first on a long list of Russian generals to be killed in Chechnya. On 19 January, despite heavy casualties, Russian forces seized the ruins of the Chechen presidential palace, which had been heavily contested for more than three weeks as the Chechens finally abandoned their positions in the destroyed downtown area.

32fxor | What were the military advantages that helped Cromwell and the New Model Army win the English Civil Wars? | [
{
"answer": "Most of this is taken from Christopher Hill's God's Englishman: Oliver Cromwell and the English Revolution. \n\nAs Hill points out, the New Model Army was a progression of ideas that had started in the Dutch Republic 'fifty or sixty years earlier'. Essential Hill argues that the essence of the revolution in the military was partly due to its reliance on 'the free way as against the formal' or the idea that free men fighting for a cause they believed in 'could get the better of mere professionals simply by superior morale and discipline'. Cromwell had raised troops (later called Ironsides) of 'picked men, well drilled, well equipped, well horsed, well paid'. Instead of using the traditional tactics of the day, displayed with aplomb by his Royalist adversary Prince Rupert of the Rhine, which used horse as a kind of mobile infantry, Cromwell instead used his disciplined troops as a 'battering ram'. \n\nWhile Rupert opted for one devastating mass charge, that would \"lose cohesion in a search for plunder and destroying enemy stragglers: 'a rabble of gentility', Monck called the royalist cavalry. As Clarendon put it...whereas Cromwell's troops, if they prevailed, or thought they were beaten and presently routed, rallied again and stood in good order till they received new orders\".\n\nAt Marston Moor, it was the repeated charges of Cromwell's horse that turned the battle from defeat to victory. So discipline and well drilled troops were an obvious factor in success, not just for the Ironsides, but for the New Model too. Hill goes on to state that the New Model's 'organization, commissariat and ordnance were normally far superior to those of the enemy. Their lieutenants were organization men... In addition to its better discipline and morale, the New Model Army had behind it better business methods, better supplies, better artillery.\n\nIt also should be noted that Cromwell and Sir Thomas Fairfax 'rarely engaged unless they enjoyed superiority in numbers. At Naseby this superiority was nearly two to one'.",

"answer": "Three main reasons, money, money, and yet more money. There were other reasons as well.\nParliament controlled not only the most prosperous and most populous parts of Britain at the start of the Civil War, which meant that their war chest was far bigger than the king's (more, and more prosperous people who were able to pay taxes), but they also controlled all of the major manufacturing centres, such as Norwich, Hull and London, which also contained nearly all of the armaments manufacturers, and, near London, at Enfield, was the only large scale gunpowder factory. As it was a Royal monopoly, it was very nearly the sole source of gunpowder in Britain. They controlled very nearly all of the big cities, thus being able to tax the trade thereof, the Navy and most of Britain's merchant fleet. Thus international trade was secure, with plenty of profitable trade to tax, and also able to pretty much prevent the king's army from easily getting supplies from abroad, even which Henrietta Maria pawning the Crown Jewels! \nParliament could, therefore, afford to equip and feed, and often pay their men, whilst the king was forced to rely on promissary notes, loans and forced loans, plunder, and demanding \"protection money\" from towns, called \"levying contributions\", and whose men were often months if not years in arrears of pay.",

"text": "The most successful parliamentary cavalry commander had been Oliver Cromwell, and Cromwell now approached the Committee of Both Kingdoms with a proposal. Cromwell had come to the conclusion that the current military system was untenable because it relied on local militias defending local areas. Cromwell proposed that Parliament create a new army that would be deployable anywhere in the kingdom and not tied to a particular locality. After the Second Battle of Newbury of 27 October 1644, where parliamentary forces greatly outnumbered royalist forces and yet parliamentary forces were barely able to defeat the royalist forces, Cromwell redoubled his arguments in favor of creating a new army. At this point, most of the leaders in the parliamentary army were Presbyterians who supported the Presbyterians at the Westminster Assembly. Cromwell, however, had also been following the goings-on of the Westminster Assembly and he sided with the Independents. Cromwell thought that the Presbyterians in the army – notably his superior, Edward Montagu, 2nd Earl of Manchester – opposed his proposal to create a new and more effective army mainly because they wanted to make peace with the king. He also thought that the army's supreme commander, Robert Devereux, 3rd Earl of Essex, shared Manchester's views. Cromwell, however, felt that parliamentary forces should seek total victory over the royalists, and since he distrusted Charles immensely, he felt that Charles should have no role in any post-war government.\n",

His army was no longer formed of the battle-hardened veterans of the Thirty Years' War who had taken the field at the battles of Newburn and Marston Moor. Many of those had perished during the Civil War and the ill-fated 1648 invasion of England. Far more had left active service after the former event, some even leaving for Swedish or French service once more. This meant that a new army had to be raised and trained by the remaining veterans. It eventually comprised some 12,000 soldiers, outnumbering the English army of 11,000 men. Though the Scots were well armed, the pressure of time meant they were poorly trained compared with their English counterparts, all of whom had served with Oliver Cromwell for years. Leslie chose therefore to barricade his troops behind strong defensive works around Edinburgh and refused to be drawn out to meet the English in battle. Furthermore, between Edinburgh and the border with England, Leslie adopted a scorched earth policy thus forcing Cromwell to obtain all of his supplies from England, most arriving by sea through the port at Dunbar.\n",

"text": "England never had a standing army with professional officers and careerist corporals and sergeants. It relied on militia organised by local officials, private forces mobilised by the nobility, or on hired mercenaries from Europe. Cromwell changed all that with his New Model Army of 50,000 men, that proved vastly more effective than untrained militia, and enabled him to exert a powerful control at the local level over all of England. At the restoration, Parliament paid off Cromwell's army and disbanded it. For many decades the Cromwellian model was a horror story and the Whig element recoiled from allowing a standing army. The militia acts of 1661 and 1662 prevented local authorities from calling up militia and oppressing their own local opponents. Calling up the militia was possible only if the king and local elites agreed to do so. However, King Charles managed to pull together four regiments of infantry and cavalry, calling them his guards, at a cost of £122.000 from his general budget. This became the foundation of the permanent British Army, By 1685 it had grown to 7500 soldiers in marching regiments, and 1400 men permanently stationed in garrisons. A rebellion in 1685 allowed James II to raise the forces to 20,000 men. There were 37,000 in 1678, when England played a role in the closing stage of the Franco-Dutch War. In 1689, William III expanded the army to 74,000 soldiers, and then to 94,000 in 1694. Parliament became very nervous, and reduced the cadre to 7,000 in 1697. Scotland and Ireland had theoretically separate military establishments, but they were unofficially merged with the English force.\n",

Well apparently yeah, you can have some receptors, called B-adrenergic receptors, lose their sensibility if constantly exposed to a drug that activate them. And one drug tha activate B-adrenergic receptor is adrenaline. \n\nHowever, they only mentioned that this desensitization happened with pharmacological drugs and they don't really mention adrenaline.

"provenance": null
},
{
"answer": "First off, I don't know of a single historical work written that long ago that still holds up on its own today. The entire profession has been reformed and then reformed again since. Of course books like his can still be influential, but you can't look at single works, let alone works that old, and then proclaim \"Aha! Now I get it!\"\n\nNext, it's a good rule of thumb is that there isn't a single explanation of cause for much of anything in history. We are, after all, talking about the history of humans and humans are complex animals. However, books will often argue, like Beard, for fairly singular causes for events such as the forming of the Constitution. This isn't wholly bad, as convincing others of, say, an economic argument requires a lot of evidence. Beard, like so many historians, needed to hammer home the idea that economics (or whatever) were an important element and that cannot be ignored. Beard probably wasn't trying to write the last word of the Constitution, ceasing all further study into the matter, and you shouldn't take it as such. I doubt very many historians actually believe that they can singularly explain historical events and eras with arguments that conveniently align with their career choices, but arguing forcefully gets the attention of employers, publishers, and grant committees. \n\nI'm sorry this doesn't fully answer your question, and I can only offer sparse insights on the Consitution itself (not my direct expertise). I can say, of course, that economics played a large but not singular role in the framing of the document, and that a number of other factors entered the Founders' mindset. These included but probably aren't limited to foreign policy/internationalism, slavery (economy but not purely so), internal cohesion (keeping the interests of small states aligned with big states), Enlightenment values, and methods of government. Anyone with better knowledge feel free to correct me.\n\nTo get all the details, it'll probably end up being best to head to the library, and the biggest name I can recommend is of course Gordon Wood. But as a bit of an exercise I'd also like to recommend David Hendrickson's *Peace Pact*, which delves very nicely into the internationalism of the Founding and the Constitution. Like Beard, Hendrickson's book is hardly the last word or gives a full understanding of the Founding, but it demonstrates quite nicely how the Founders could be internationally minded in their plans for the country, taking into account far more than the domestic factors people usually think of when describing the writing of the Constitution. It would make for a great read.",

So a large current and small radius both combine to produce large power loss. That generates heat. Heat increases resistance also, so without cooling, you would get a run away effect until something failed. ",

And one of the biggest ways was with our stomachs - it's likely that human hunting played a major role in the disappearance of all the megafauna species in the new world, starting perhaps 10- to 20,000 years ago.",

"answer": "If you look at the actual [study](_URL_0_), what it says is that humans have been drastically increasing the extinction rate since 1500 and it's become even worse in the last 100 years. In other words, from 1500 - 1900 it was bad and from 1900 - present it's become really, really bad (about 3 times as many species went extinct between that 1900 and 2016 than between 1500 and 1900. That's about 12 times as much per 100 years).\n\nThe study doesn't say why 1500 was chosen as the cutoff point, but it emphasizes that it is measuring the impact of modern human activity on extinction events. I would speculate that 1500 was chosen because most historians consider sometime around 1500 to be the start of \"modern history\" since that's when we started having large scale travel across the globe and because 1500 is a nice, round number.\n\nHuman activity in 1500 still caused extinctions because humans hunted some animals to extinction and others had their habitats destroyed. Humans may not have had cars or plastics back then, but they knew how to deforest large areas of land for agriculture and had few qualms about hunting anything edible.\n\nHere's the relevant quote from the study:\n\n > Our results indicate that modern vertebrate extinctions that occurred since 1500 and 1900 AD would have taken several millennia to occur if the background rate had prevailed. The total number of vertebrate species that went extinct in the last century would have taken about 800 to 10,000 years to disappear under the background rate of 2 E/MSY (Fig. 2). The particularly high losses in the last several decades accentuate the increasing severity of the modern extinction crisis.",

This is very useful for when some major national decision needs to occur, and the ruling party thinks they are at an advantage concerning that decision. The election somewhat becomes a national referendum on that issue, with the people voting to put people into government that agree with them about that issue. So if the US system had snap elections maybe Obama would have called one early on in the health care debate, or Bush might have called one before the wars in Afghanistan or Iraq.

3kwz08 | after world war ii, what changes did germany make to it's own political system to ensure a dictator figure could never take power again? | [
{
"answer": "My answer won't fully describe your question, but one of the main reasons dictators weren't allowed to rise *immediatley*, and for the 40 or so years after the fall of Hitler, is the fact that Germany was split into two. The eastern half was controlled by the USSR, and the west was controlled by the western allies. The USSR implemented their own leaders, and the western allies kept a large hold on their own sectors. This would have meant leaders would have been kept under control to a large extent. \n\nNot sure if you already knew this. But there we go! Someone correct me if I'm speaking out of my ass. ",

In his desire and stated political aim of expanding the living space (\"Lebensraum\") of the German people by destroying or driving out \"lesser-deserving races\" in and from other territories dictator Adolf Hitler may have devised an ideological system of self-perpetuating expansionism, in which the expansion of a state's population would require the conquest of more territory which would, in turn, lead to a further growth in population which would then require even more conquests. In 1927, Rudolf Hess relayed to Walter Hewel Hitler's belief that world peace could only be acquired \"when one power, the racially best one, has attained uncontested supremacy\". When this control would be achieved, this power could then set up for itself a world police and assure itself \"the necessary living space...

28tkv4 | Was New Zealand really forced out of the British Empire? | [
{
"answer": "I think your professor's language is a bit harsh, but he is trying to emphasize a point.\n\nNew Zealand (along with Canada, Australia, and a few other countries) didn't achieve independence in an abrupt manner in the same way India and the USA did. These countries made a gradual shift towards self-governance.\n\nThe biggest changes occurred after Britain passed the Statute of Westminster in 1931. Some countries (like Canada) then took responsibility for passing their own laws, and managing their external affairs. Some countries (like New Zealand) we're required to specifically adopt the statute, which New Zealand did not do until 1947.\n\nSo, it's not like New Zealand got \"kicked out\" in in 1931 (or 1947), but the message from mother England was clear. The large (even NZ), established dominions were ready to take the next step towards self-governance. By 1947, colony divestment was in full swing. As JBC mentions, Queen Elizabeth II is still the head of state.\n",
"provenance": null
},
{
"answer": "It was not really forced out, but we did not really elect to leave either. The issue was that, prior to 1950, NZ had two houses of parliament - the Legislative Council (the upper house) and the House of Representatives (lower house). However, the upper house was effectively useless - its members were not elected, but instead were appointed by the Governor-General on the recommendation of the Prime-Minister. Since the GG tried to stay out of politics entirely, the LC evolved into nothing more than a rubber stamp for the PM - he chose it's members and they just signed off on Bills that got through the lower house.\n\nAs this was wasteful, the NZ government decided to abolish the LC. BUT it had been established by the New Zealand Constitution Act 1852 - an Act of the *British* Parliament. Since the NZ government could not override an Act of the British Parliament (or, rather, there was uncertainty if it could or not) Parliament took the \"easy\" option of first adopting the Treaty of Westminster, *then* abolishing the LC. \n\nBecoming independent from the UK was a side effect of adopting the ToW - it wasn't that we *wanted* independence, but in order to do what we wanted to we (possibly) needed it. \n\nSource: *Constitutional and Administrative Law in New Zealand* by P. Joseph",

New Zealand's constitutional history is really one of an odd sense of laziness and contentment with the status quo until something doesn't work - if it ain't broke, don't fix it. Partially the reason why we still have an unwritten constitution. \n\nNew Zealand wasn't the only Dominion in the situation - the Statute only automatically applied to Canada, the Irish Free State and South Africa.

For most of its history, New Zealand had been, economically, culturally and politically, highly dependent on Britain. This began to change during World War II, when it became clear that Britain was no longer able to defend its former colonies in the Pacific. As Britain began to turn away from what was left of its former Empire and towards Europe, New Zealanders became less inclined to think of themselves as British. Initially the country turned instead to the United States, and so entered into the ANZUS pact with the US and Australia, and aided the US in the Vietnam War. However, by the early 1970s many New Zealanders felt the need for genuine national independence, a feeling strengthened when Britain joined the European Economic Community in 1973, causing serious problems for New Zealand trade.

Common examples are the proceedings of a court hearing such as a criminal trial (by a court reporter) or a physician's recorded voice notes (medical transcription). Some transcription businesses can send staff to events, speeches, or seminars, who then convert the spoken content into text. Some companies also accept recorded speech, either on cassette, CD, VHS, or as sound files. For a transcription service, various individuals and organisations have different rates and methods of pricing. That can be per line, per word, per minute, or per hour, which differs from individual to individual and industry to industry.

8zn4u9 | How common was wearing masks in renaissance Venice? | [
{
"answer": "Venetian masks outside of carnival (which only lasted for the month before Lent) and theater/masquerade were not so much a thing in the Renaissance; according to James Johnson in *Venice Incognito: Masks in the Serene Republic*, the practice began among the male and female nobility in the late seventeenth century and soon spread to all ranks of society, lasting until the Venetian Republic fell to Napoleon in 1797. Foreign visitors to Venice expected the city to be full of masked revelers and assassins, but found a whole lot of ordinary shoppers and bystanders that happened to be wearing a covering on their faces. While carnival masks gave the wearers a freedom to act outside of social norms - women could associate with anyone, since they were unrecognizable, and male crossdressers (*gnaghe*) could walk around freely - everyday masks had a very different context.\n\nAs the wealthy returned from their estates outside the city in October and the theatrical and social season began, masks reappeared in the piazzas of Venice, most people wearing the combination of the *tabàro*, a long black cloak; *baùta*, a black hood; and *larva*, a white mask that flared out at the bottom to allow for talking and eating. The *larva* was usually held on by being tucked under a cocked hat that sat low on the head, but while men always wore such headgear, women did not; when the latter were bareheaded or in another sort of hat or a plain cloak, they tended to wear a black *morèta* mask, which was instead held to the face with a tab or button they kept between their lips. After Lent, the theaters closed again and masks were less prevalent, but when they opened again in the late spring for Ascension, the masks reappeared (though worn with the *baùta* pulled down to mitigate the heat and humidity). The church tried to regulate on what days and at what times masks could be worn, but by 1720 they were normalized as a part of everyday dress during the proper season.\n\nSome did, of course, use the natural advantage of the *larva*: hired thugs, prostitutes at the theater, and booksellers with obscene material wore masks on a regular basis to protect their identities while doing illegal things. Others wore masks out of less pressing necessity, but still to remain incognito, like men running private messages and the city's surveillance agents. However, there was another end of the spectrum, where the mask was worn as an indication of formality and respect. Members of the nobility would dress in *larve* when attending the introductions of new ambassadors or greeting foreign royalty traveling incognito in their own masks, when a new doge was elected or the doge's children were married, for particular religious or historical commemorative ceremonies.\n\nThe habit of masking was believed to have led to rising crime rates early in the eighteenth century, and could lead to all kinds of comedies of errors - but it was entrenched in Venetian custom and normally was seen as completely unremarkable.\n\n",

These grew out of the earlier revels and had become evident by the 15th century in places like Rome, and Venice, where they developed as entertainments to enliven towns and cities. Thus the Maundy Thursday carnival in St Marks Square in Venice, attended by the Doge and aristocracy also involved the guilds, including a guild of maskmakers. There is evidence of 'commedia dell'arte' inspired Venetian masks and by the late 16th century the Venetian Carnival began to reach its peak and eventually lasted a whole 'season' from January until Lent. By the 18th century, it was already a tourist attraction, Goethe saying that he was ugly enough not to need a mask. The carnival was repressed during the Napoleonic Republic, although in the 1980s its costumes and the masks aping the C 18th heyday were revived. It appears other cities in central Europe were influenced by the Venetian model.\n",

Nelson notes that the sex ritual combines elements of Venetian Carnival and Catholic rites, in particular, the character of \"Red Cloak\" who simultaneously serves as Grand Inquisitor and King of Carnival. As such, Nelson argues that the sex ritual is a symbolic mirror of the darker truth behind the façade of Victor Ziegler's earlier Christmas party. Carolin Ruwe, in her book \"Symbols in Stanley Kubrick's Movie 'Eyes Wide Shut\"', argues that the mask is the prime symbol of the film. Its symbolic meaning is represented through its connection to the characters in the film; as Tim Kreider points out, this can be seen through the masks in the prostitute's apartment and her being renamed as \"Domino\" in the film, which is a type of Venetian Mask.\n",

In medieval Europe, masks were used in mystery and miracle plays to portray allegorical creatures, and the performer representing God frequently wore a gold or gilt mask. During the Renaissance, masques and ballet de cour developed - courtly masked entertainments that continued as part of ballet conventions until the late eighteenth century. The masked characters of the Commedia dell'arte included the ancestors of the modern clown. In contemporary western theatre, the mask is often used alongside puppetry to create a theatre which is essentially visual rather than verbal, and many of its practitioners have been visual artists.\n",

17kd6p | When alcohol is poured into a hot (for example almost boiling water) liquid does it vaporise? For example whiskey in an irish coffee or anything similar? | [

"answer": "Yes, alcohol can vaporize. This fact is utilized in [distillation](_URL_1_) to separate alcohol from solution. You can see from this [phase diagram](_URL_0_) that the boiling point of a water/ethanol solution is lower than that of water alone. However, distillation relies on constant heat source - vaporization is an endothermic process, meaning the solution cools down when alcohol vaporizes.

If this is done in a partially enclosed space, and the vessel allowed to be full of hot gas, when the heat is taken away, the gases cool and as they do, the amount of liquids that the gas can hold will decrease. Therefore, most of the moisture and alcohol held in the gas will condense. As the gas cools, it decreases in volume, and the pressure drops. Thus when the flaming alcohol in a backdraft is covered with a pint glass over a saucer, the dense, cold air is replaced with less dense, warm air with a lot of alcohol vapour held in it. As the oxygen flow to the fire is restricted, the remaining oxygen is used up and the fire in the pint glass goes out, removing the heat source. The alcohol-laden warm air now in the glass cools and begins to create a pressure difference. The air outside the pint glass forces its way into the partially evacuated pint glass and is responsible for pushing any liquid at the outside bottom of the pint glass further inside (as the seal of the glass and the saucer is not perfect) as it begins to equalise the pressure difference. Once the majority of the liquid is inside the upside down pint glass, sometimes further air can be seen to bubble up into the glass. At some point an equilibrium will occur, where the pressure difference between inside and outside of the glass is equal to the pressure of the column of liquid held up inside, and this will hold the liquid inside the glass. Sometimes, when a good seal is made, the pressure difference between the inside and the outside of the glass exerts a great enough force that when the glass is lifted, the saucer will remain stuck to its underside.\n",

29y1hb | How can some materials resist being dissolved by both polar and non-polar solvents? | [
{
"answer": "Per your example, glass, there are solvents that will dissolve it. What makes it more resistant than most materials is it's crystal structure, which is in a lower energy state than most compounds. In order to be converted into another compound, the overall energy (via entropy and thermodynamics) must be lower than the original compound. If it isn't favored by a lower energy state, it will react at a much lower rate. ",
"provenance": null
},
{
"answer": "While the chemical bonds in glass are slightly polar, the bonds that hold the atoms together are quite strong and also form a very large interconnected network. It's as if the whole piece of glass were one molecule.\n\nIt's not possible to dissolve it simply by surrounding it with solvent molecules. You'd need a solvent that is strong enough to nibble away at the silicon-oxygen bonds that make up silica. On top of this, you are essentially constrained by the fact that these chemical reactions must take place at the surface of the glass.",

Strongly polar compounds like sugars (e.g. sucrose) or ionic compounds, like inorganic salts (e.g. table salt) dissolve only in very polar solvents like water, while strongly non-polar compounds like oils or waxes dissolve only in very non-polar organic solvents like hexane. Similarly, water and hexane (or vinegar and vegetable oil) are not miscible with each other and will quickly separate into two layers even after being shaken well.\n",

This is principally because the resulting ion–dipole interactions are significantly stronger than ion-induced dipole interactions, so the heat of solution is higher. When the oppositely charged ions in the solid ionic lattice are surrounded by the opposite pole of a polar molecule, the solid ions are pulled out of the lattice and into the liquid. If the solvation energy exceeds the lattice energy, the negative net enthalpy change of solution provides a thermodynamic drive to remove ions from their positions in the crystal and dissolve in the liquid. In addition, the entropy change of solution is usually positive for most solid solutes like ionic compounds, which means that their solubility increases when the temperature increases. There are some unusual ionic compounds such as cerium(III) sulfate, where this entropy change is negative, due to extra order induced in the water upon solution, and the solubility decreases with temperature.\n",

Even if some of the image shows, there is usually a reflection on the screen obscuring some of the image.\n\nIn short, phones are simply not designed to be used with front lighting, so the backlight must be kept on at least a little bit to ensure the screen and its controls are all visible.",

In practice, there is a small difference, which means that every pixel flickers at about 30 Hz.

Unfortunately, many of these people don't know that their eye-strain is being caused by the invisible strobe effect of PWM. This problem is worse on many LED-backlit monitors, because the LEDs switch on and off faster than a CCFL lamp.\n",

Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion (or opening) of the urethra and is therefore not used for urination. The clitoris also usually lacks a reproductive function. While few animals urinate through the clitoris or use it reproductively, the spotted hyena, which has an especially large clitoris, urinates, mates, and gives birth via the organ.

However, Gould acknowledged that \"most female orgasms emanate from a clitoral, rather than vaginal (or some other), site\" and stated that his nonadaptive belief \"has been widely misunderstood as a denial of either the adaptive value of female orgasm in general, or even as a claim that female orgasms lack significance in some broader sense\".

He believes that the penis cannot come in contact with the congregation of multiple nerves/veins situated until the angle of the clitoris, detailed by Georg Ludwig Kobelt, or with the roots of the clitoris, which do not have sensory receptors or erogenous sensitivity, during vaginal intercourse. He did, however, dismiss the orgasmic definition of the G-spot that emerged after Ernst Gräfenberg, stating that \"there is no anatomical evidence of the vaginal orgasm which was invented by Freud in 1905, without any scientific basis\".\n",

Quite simply, there is no such thing as a medium that is not biased, because all human beings are, by nature, biased.\n\nThe trouble is that as soon as you start making laws about what news media may or may not report, you introduce the possibility of government censorship, and that is never a good thing. You *can* make laws preventing people from spreading deliberate lies, but you *can't* make laws forcing people to be neutral -- because who decides what's \"neutral\" and what isn't?\n\nIt may be more noticeable in the US than in most European countries, but that's all it is -- more noticeable. But compare, for example, the BBC, ITN and Channel 4 News in the UK. The differences are subtle, but they're there; look to see, for example, whether they say \"government cutbacks\" or \"government savings\".\n\nSo we have lots of different news organisations, each with their own set of biases.

1erksa | How did the people of Imperial Japan view their German allies in WW2 and vice versa? | [
{
"answer": "I can't give a full answer but Imperial Japan was very strict on censorship. I'm pretty sure Mein Kampf was banned. Foreign influence, especially western influence was considered a bad thing. And at the same time Nazi Germany was at war with The USSR, Japan maintained a non aggression pact. This hurt Germany because it allowed for the USSR to move troops off the Manchukuo border to the very important Eastern Front against the Nazis. Moreover the allies had dominance over the oceans in the latter parts of the war making supply exchange difficult if not impossible (sometimes submarines were used to move diplomats, although Im not sure how often). And there were information exchanges on weapons, military supplies, although this was also limited. But for the most part it was just a written alliance and not much else (to my knowledge).\n\nSource: BA in history. \n\nEdit: spelling",

I'm by no means an expert. Cancercures, during the Meiji Period (1868-1912), they did send people around the world to learn about other cultures and governments (this was after a long period of enforced international isolation).

There was even some sympathy on Britain's part b/c the Japanese made a strong defense of Shanghai, which had a large foreign presence that included a lot of Brits.\n\nSo, I'd say it wasn't their first choice, but it made a lot of sense to ally with Germany. \n\nedit: some grammar crap",

While the term was not invented by or well-defined by the Nazis its complexity and lack of clear definition is something we should keep in mind when discussing the community and society which they sought to build.\n\nIf you are able to access academic journals I would recommend the work of Marynel Ryan on the topic along with the books of Claudia Koonz and Milton Mayer.",

Operation Overlord called for the British Second Army to assault between the River Orne and Port en Bessin, capture the German-occupied city of Caen and form a front line from Caumont-l'Éventé to the south-east of Caen, in order to acquire airfields and protect the left flank of the United States First Army while it captured Cherbourg.

1redsm | what does it mean to "rewire" your brain? is it possible? if so, how? | [
{
"answer": "Wires are a common analogy for neurons, the main cells of your brain (and the rest of your nervous system.) It's a fair comparison: neurons are long and thin, rapidly conduct electricity to carry signals, and even have a coating of insulation.\n\nNeurons communicate with other neurons at points called synapses, where they almost but don't quite touch. Instead, one neuron sends chemicals called neurotransmitters to the next neuron; different chemicals make the next neuron more or less likely to keep the signal going.\n\nWhereas most body cells divide to make more of themselves, neurons mostly only come from neural stem cells. By adulthood, your brain has (almost) all the cells it will ever have. As a result, you can't rely solely on making new neurons to make new memories, learn new things, change your emotions, and such.\n\nSynapses, on the other hand, can be made or eliminated (and strengthened or weakened) throughout your entire life. This process of changing the connections between brain cells is what \"rewiring\" broadly describes. In that sense, rewiring happens anytime you learn anything, make a new memory, or even use an old memory; it happens every minute of the day. People commonly use \"rewiring\" to mean something more like \"changing my patterns of thinking or behavior in the long term,\" which is obviously a little harder than making a new memory, but still very much possible. We'd have given up on cognitive-behavioral therapy a long time ago if it weren't.\n\nBig picture: Given that you have maybe one hundred billion neurons, each with thousands of synapses, the total number of connections is likely in the hundreds of trillions. This helps give an idea of how the brain, which resembles a three-pound blob of fatty Jello, can be responsible for everything you've ever felt, learned, or experienced.",
"provenance": null
},
{
"answer": "\"Neurons that fire together wire together.\" If you have a memory that brings to distressed feelings, every time you take yourself through the memory, those feelings will be even more strongly associated with the memory, even if your memory becomes faulty. The worst part of this type of memory is the association with out of control emotions that may escalate too quickly so you feel physically bad as well. \n\nAnyway, what you can do in this case is to break the memory into parts, like movie clips, and in between clips, imagine a moment that is strongly positive: like locking eyes with a loved one or your puppy, so you get a little oxytocin. Then play the next step back, rinse, repeat. Do it a few times and the memory won't play all the way through anymore so easily, nor will those negative emotions escalate like they did before.",

Certain sounds cause the person to feel certain things in turn, or see spots of color dance across their vision. Neurologists agree that this occurs of faulty wiring in the brain, that \"neuron circuits that process a sense accidentally strum circuits of another sense, causing both to go off simultaneously\". It is debated how this happens. As a child, one possesses more neurons than necessary and the unnecessary ones are pruned away and die when not used.

Both mechanisms of rewiring are useful for learning completely novel tasks that may require entirely new connections between regions of the brain.

1ctvbc | Are the recent Iranian and Chinese earthquakes related given both of their positions along the Indian Plate? | [
{
"answer": "Ahh it's 2:35 AM but I love this topic so I'm going to give it a shot. \n\nShort answer: YES we think something is going on. \n\nI like the maps you linked, but I would like you to look at [this world map](_URL_1_) and this [map of the major tectonic plates](_URL_3_), bear in mind they are not aligned (i.e. North America is in the centre of one map, and the right hand side of the other)\n\nDo you see the Indian, and Australian plate? We don't usually differentiate them, but there has been a theory that the Indo-Australian plate has been ripping apart slowly for millions of years. [This map](_URL_5_) shows the plate itself a little better. Basically, the bottom half is being pushed into the relatively soft Pacific Plate in the south, and causing the Himalayan Orogeny (mountain building) in the north (i.e. being pushed into hard rock). This is causing the southern end of the plate to move faster than the northern half creating a shear zone in the centre approximately 500km off the western coast of Sumatra. \n\nThere have been lots of articles talking about why we think this, so I'm going to let them do the talking [ABS Science](_URL_4_), [Voice of America News (never heard of the source but article checks out)](_URL_0_), and one of the latest and most definitive [paper in Nature](_URL_2_).\n\nThis shearing is causing earthquakes around all the plate boundaries, but it is not any unexpected or cataclysmic geological event. Geologists know what's going on, have a fairly good idea of why it's happening, but there isn't anything we can do to stop it- but there are things we can do to minimize the risks associated with it.

"answer": "the reasons to have a c section are usually because of something wrong with the way the birth will take place that has nothing to do with the preparedness of the baby for life, or its 'darwinistic fitness'...c section babies show no higher rate of birth defect or cognitive problems than a regular birth, so they are just as strong mentally and physically. A child's inability to escape the imbilical cord wrapped around his/her neck has nothing to do with mental function for example",

},
{
"answer": "I don't think so. In the past, c-sections were used even if they weren't even necessary. It was a money maker. I do believe their are midwives who are trained in breach deliveries, also. \n\nOf course, without c-sections, there would be a higher mortality rate, but I really can't believe it could be linked to mental health...\n\nNow, our society and the many issues we face, that's another story. \n\n",

For example, a prolonged period of time without access to oxygen during the delivery can lead to brain damage and mental retardation. Also, low birth weights have been linked to lower intelligence scores later in lives of the children. There are two reasons for low birth weight, either premature delivery or the infant's size is just lower than average for its gestational age; both contribute to intellectual deficits later in life. A meta analysis of low birth weight babies found that there is a significant relationship between low birth weight and impaired cognitive abilities; however, the relationship is small, and they concluded that, although it may not be relevant at an individual level, it may instead be relevant at a population level. Other studies have also found that the correlations are relatively small unless the weight is extremely low (less than 1,500 g) – in which case the effects on intellectual development are more severe and often result in mental retardation.\n",

5aelol | regarding death valley, why is being 86 m below sea level so much more extreme than being 86 m above it? | [
{
"answer": "The elevation actually doesn't have anything to do with it being extreme. It's the giant mountain ranges to the west that block all the rainfall and its geographic location in an area of few clouds, a somewhat southern lattitude, and lots of sunshine that make it a hot, baked desert. Lots of death valley is 86 M and higher, and it's just as hot there as it is on the valley floor. \n\nThe high mountains make what is called a 'rain shadow' effect - any moisture falls on the mountains, which are at 14,0000 feet on one range (the Sierra Nevada) and then another 14,000 foot range (White Mountains) after another valley. They pretty much take almost all the rain out of the clouds by the time they get over death valley. ",

The environment acts as an external stimulus, and tactile perception is the act of passively exploring the world to simply sense it. To make sense of the stimuli, an organism will undergo active exploration, or haptic perception, by moving their hands or other areas with environment-skin contact. This will give a sense of what is being perceived, and give information about size, shape, weight, temperature, and material. Tactile stimulation can be direct in the form of bodily contact, or indirect through the use of a tool or probe. Direct and indirect send different types messages to the brain, but both provide information regarding roughness, hardness, stickiness, and warmth. The use of a probe elicits a response based on the vibrations in the instrument rather than direct environmental information. Tactual perception gives information regarding cutaneous stimuli (pressure, vibration, and temperature), kinaesthetic stimuli (limb movement), and proprioceptive stimuli (position of the body). There are varying degrees of tactual sensitivity and thresholds, both between individuals and between different time periods in an individual's life. It has been observed that individuals have differing levels of tactile sensitivity between each hand. This may be due to callouses forming on the skin of the most used hand, creating a buffer between the stimulus and the receptor. Alternately, the difference in sensitivity may be due to a difference in the cerebral functions or ability of the left and right hemisphere. Tests have also shown that deaf children have a greater degree of tactile sensitivity than that of children with normal hearing ability, and that girls generally have a greater degree of sensitivity than that of boys.\n",

22o6pj | why in 2014 is the ocean still such a mystery. we overcame obstacles to space travel 50+ years ago but can't figure out water. | [
{
"answer": "We actually can do some pretty cool things in water. We get oil from miles below a surface that is miles below the waves, we explore at tremendous depths, and we lay cables that stretch the length of the oceans. \n\nIt's true that there's still a lot left to do, and we certainly could do a lot more. But the reason we seem to be behind compared to space has less to do with pressure than with light (or electromagnetic waves more generally). \n\nThe reason we know so much about space is that we can see really far, and what we see contains a lot of information in the form of light spectrums, positions, speeds, etc... Also, most of the things we look at are really big, and stand out clearly from the background. \n\nWater, on the other hand, blocks all of that. It scatters light, scatters heat, and makes info gathering a much more personal and in your face endeavour. ",

"answer": "We really do not know much about the universe. We have examined a few square kilometers of the moon, and about the same amount of mars. We have seen a few square meters of Venus. Not much at all.\n\nMost of what we know about the universe is because the universe is clear, so all we have to do is look. We can only see through a few tens of meters of water. Beyond that you need sonar. Or the equivalent of space suits for underwater - scuba gear, diving suits or submarines.\n\nA space suit or space craft only needs to withstand pressures of 1/2 of an atmosphere, in tension - keeping a livable atmosphere within. Go down 5 meters, and you will have an extra 1/2 atmosphere or pressure pushing in. And holding a pressure in is way easier than keeping one out.\n\nSo examining the universe is hard, so we haven't done all that much of it. Examining the deep ocean is even harder, and we have done quite a lot of that.",

I'm studying mechanical engineering right now with the full intention to try to go into the ocean exploration field, and I can say that the engineering challenges of withstanding the immense pressures, as well as lack of funding for ocean science exploration compared to space exploration is a huge disparity. However, James Cameron was able to go down to the bottom of the Mariana Trench 2 years ago, which was the first notably serious progress for the field in a long time, but the main future for the field is in Autonomous Underwater Vehicles (aka AUVs) and Remote Operated Vehicles (ROVs) which is what I've been working with and hope to do for a living! With global warming eventually causing our oceans to rise and our land based non renewable resources being strained, it's only a matter of time before the other 71% of the Earth becomes even more crucial to explore! Hopefully my enthusiasm has helped a bit!\n\nAlso another thing: Materials/mechanisms for withstanding these pressures have barely been developed. Compared to space (someone else commented with those pressure details) the material/boundary layer properties you need for the deep ocean is ridiculous. I believe a visual I was told once was at the bottom of the Marianas trench for every square inch, you'd be balancing a land rover car on it.\n\nFinal edit for the night after reading more comments: For those questioning how lucrative the field could be, I think this serves as just one example: _URL_1_\nThere's more than just oil out there, but at the same time we need to start worrying about the environmental costs more.

(2) It's complex and interesting, so you only see a very sanitized and simplified version of it designed for laypeople. (3) The stakes are low, so incentives and a sense of urgency isn't there. Think of medical doctors and how much more pessimistic they are about their jobs. That's because they know that they're lightyears away from achieving immortality if they ever can at all, because they're faced with failure and heavy consequences daily; to them it's just a practice. Astrophysicists on the other hand can tend to be more optimistic, [because they don't know what they don't know](_URL_0_) and their margin of error isn't as obvious or important. The universe could be a trillion years old and they could be wrong and never know it, and it might never matter in their lifetimes.\n\nSo astronomy is bound to have a somewhat unrealistic public face. I'd say that oceanic mysteries are more obvious because our contact with the ocean is more direct and palpable, and so we're less innocent about our ignorance thereof.\n\nI think the answer is just perception, not actual achievement.

One can go for a spacewalk; one cannot go for a walk at the bottom of the Challenger Deep (deepest part of the ocean at 10,916m or 35,814ft). The tremendous pressure makes it difficult for any human or vessel to navigate at those depths. \n\n4) Studying creatures at these depths is very difficult as they tend to be elusive. It was only 2013 that we were able to observe a giant squid (Architeuthis) in its natural environment. The relative difficulty of studying life at these depths probably won’t drive innovation as much as space exploration will. \n\n5) Making contact with an alien is much more exciting than making contact with a fish. We know there are life forms in the ocean, we do not know if there are life forms in space. \n\n6) The space race of the 1960’s cemented a competitive curiosity about space in the human conscious. It was a great sense of pride for America to win (regardless of what the conspiracy theorists will tell you). The concept of the deep-sea race has never entered popular conscious. \n\n7) There is much more media based on space (Star Wars, Star Trek, Aliens etc.) than there is on the deep sea. This media generates interest, which in turn, generates funding. You can go to space camp; you can’t go to deep-sea camp. \n",

"answer": "Woohoo something I know about! I'm a senior history major who focuses on tech development throughout the 20th-21st centuries, and there are really two answers to this question.\n\n1.) There is a technological component. This has been overcome to some degree in both fields. Think of it this way: beside speed constraints, gravity, radiation and total solitude, the basic things a spacecraft supporting life must do is 1. get up into space and 2. deal with the vacuum of space. We've known how to keep people warm and contain an atmosphere for years. So that's not really special. We've dealt with radiation since the 1800s, and gravity is mostly only an issue on long trips. Basically, we're really good at living in space near earth for short periods of time. We're woefully inefficient at sending objects into orbit, but we do get them up there with brute force. Here's the cool thing about a vacuum: the most vacuous it can be is absolutely nothing. So we only had to build ships that could withstand the negative pressure of absolute nothingness. We've had that technology for years as it often only requires things to simply be sealed really well. If you look at modern spacecraft, they're not thick. They're actually thinner than your average car, but they have MUCH better gaskets. The ocean is a different story. Positive pressure, for all intents and purposes, can grow infinitely (short of creating a black hole of course). Think of it like this: you can only remove so much before there's nothing, but you can add as much as you want and you create more pressure that way. Submarines have to be incredibly thick-hulled. This creates weight limits and propulsion limits. Put simply, subs can only handle as much pressure as they have material to withstand it, and no man-made objects can withstand infinitely intense pressures. We actually have sent people to the deepest point in the ocean, but fewer people have been there than on the moon. \n\n2.) It's a political game. This actually describes the issue much better. We, as a species, can do really cool things when we set our minds to it. The space race happened because we had to compete with one another. Going to the bottom of the ocean never had the funding and research that walking on the moon had. We could explore the ocean much more deeply because we do have the technology, but we don't back it with the funding that we did the space race. Of course, now both fields suffer from a disgusting lack of funding.\n\nTl;Dr: Pressure and politics \n\nP.S. and physicists or engineers who wish to add or correct, please feel free. I don't claim to know the exact science, but I do know the development process.\n ",

The Ocean floor is littered with debris from our civilization and ever island, bay, inlet, and depth, has been named and charted.\n\nSo basically my answer is that the questions premise is flawed.

"answer": "It's not actually all *that* mysterious. Environmentalists love to make it sound way bigger and more unknown than it really is. In reality, a great deal of oceanography was done back during the Cold War (a time when knowing how fast you could move ships around and where you could hide submarines was *really important),* and scientists have a pretty good idea of what's what in the ocean these days.\n\nIf you're referring specifically to the difficulty of finding stuff (malaysian airplanes, for instance) in the ocean on short notice, that's mostly because the ocean blocks radio waves and pretty much all other kinds of light quite effectively over long distances. It's easier to see stuff in space because there's nothing between you and the stuff like there is underwater.\n\nGetting into space also presents rather different challenges than getting into the deep ocean regions. In space, pressure is relatively easy to deal with (you just need a balloon that can hold in 10^5 N/m^2 ) but you have to work against a huge gravity well. Underwater, gravity is on your side (anything that's buoyant floats, anything else sinks), but you need a rigid hull that can hold out enormous amounts of external pressure.",

ISIS flags are popping up everywhere (Greece, Belgium, the continent of Europe in its entirety, hell there was an isis flag posted near the white house), and even though another group claimed responsibility for the France attacks, one of the shooters still claimed on video that he supported ISIS. \n\n It's especially volatile now that the West is looking at their expansion and all the horrible shit that comes with it; crucifying/beheading kids/suicide bombings/mass murder/slavery and saying they will stop it.

The US has laws, and abides by international laws, that prevent them from entering sovereign countries without their permission or declaring war on the sovereign country.

They've become notorious for their brutality.\n\nI'm not really sure why your professor considers them in particular such a major threat.

5lpzo7 | What are the roots of anti-intellectualism in the United States? What is its history? | [
{
"answer": "Awesome question. The classic answer can be found in Richard Hofstadter's 1963 book, *Anti-Intellectualism in American Life*. Hofstadter, who went on to win the 1964 Pulitzer Prize for non-fiction for the book, wrote:\n\n > \"Anti-intellectualism . . . is founded in the democratic institutions and the egalitarian sentiments of this country.\"\n\nFor Hofstadter, who traces anti-intellectualism to broadsheets levied against some of the first American presidential candidates, the roots go to the classic American debate between who governs best. Is it the mob, the vast majority of Americans who have little interest or knowledge in a topic, or is it a smaller and traditionally less representative group of people who have more experience and education on a topic?\n\nAs Woodrow Wilson said in 1912: \"What I fear is a government of experts. God forbid that in a democratic country we should resign the task and give the government over to experts. What are we for if we are to be scientifically taken care of by a small number of gentlemen who are the only men who understand the job?\"\n\nHofstadter is still quoted frequently on this topic, but there are a lot of things he missed discussing, as Nicholas Lemann points out [in a wonderful 50th anniversary retrospective review](_URL_0_).\n\nHofstadter (and plenty of people today) think of anti-intellectualism as solely the domain of the political right. But Hofstadter missed people like Donald Kagan, Robert Bork, Jeane Kirkpatrick and Allan Bloom, who wrote *The Closing of the American Mind.*\n\nHe also tended to describe business as anti-intellectual, when we know that today, business is one of the most intellectual-friendly branches of American society. America today hosts designers and inventors, innovators and trend-makers, rather than industrialists and manufacturers as it did in 1963, when Hofstadter was writing.\n\nHe also missed the rise of the Civil Rights movement for women and minorities in the United States.\n\nThat's getting a little off track, however. The bottom line is that there is (and has been) a constant push-pull between appeals to the \"mob\" and the \"elite\" in American society.\n\nIn *Empire of Liberty: A History of the Early Republic,* Gordon Wood contends that the first 30 years of the United States resulted in a switch from the desires of the nation's founders ─ who were the elite of the nation ─ to the will of the middling people, those involved in commerce and enterprise.\n\nThe founders of the United States had envisioned a Congress and President who were already wealthy and thus immune from corruption. The thought went that they would be self-sacrificing and put aside their businesses to serve the national good for a period, then return to their own interests afterward. \n\nJoyce Appleby and Wood contend that the middle classes, who enriched themselves through industry and enterprise, developed a belief that the self-made man was the ideal politician, not someone who had been born wealthy, was educated, and thus theoretically could be trusted to make a decision without being swayed by public opinion.\n\nAnd so we have a push and pull, dating back to the roots of the United States.\n\nHofstadter also makes the case that evangelical Protestantism in the United States, particularly in the South, strongly contributed to anti-intellectualism in the latter half of the 19th century and the 20th century. Mark Noll's *The Scandal of the Evangelical Mind* is a more in-depth analysis of this aspect.\n\nNoll has done some excellent work on American religious history (I highly recommend his *The Civil War as a Theological Crisis*) and he explains that a lot of the American evangelical anti-intellectualism can be traced back to the development of a \"literalist\" interpretation of the Bible as a response to the anti-slavery movement of the 19th century. Before the 19th century, and particularly before the French Revolution, churches and religious organizations tended to be pro-science if they were anything. \n\nIn the United States, this began to change as the arguments about slavery intensified. As Noll points out, the Civil War caused many churches to fission into southern and northern branches, based upon their beliefs in slavery. Northern churches tended to favor an interpretation-based view of the Bible, while Southern churches stuck with a much more literal interpretation of the Bible. Forex, since the Bible refers to slavery and the proper treatment of slaves, it must be appropriate to have slavery in the United States, they argued.\n\nThis literalist philosophy was later applied to things as varied as racial segregation, abortion, and global warming. Because of its reliance upon scripture as the absolute (literally Gospel) truth, anything that took a different viewpoint was seen in a dim light.",

In so doing, he explored questions regarding the purpose of education and whether the democratization of education altered that purpose and reshaped its form. In considering the historic tension between access to education and excellence in education, Hofstadter argued that both anti-intellectualism and utilitarianism were consequences, in part, of the democratization of knowledge. Moreover, he saw these themes as historically embedded in America's national fabric, an outcome of its colonial European and evangelical Protestant heritage. He contended that American Protestantism's anti-intellectual tradition valued the spirit over intellectual rigour. He also noted that Catholicism could have been expected to add a distinctive leaven to the intellectual dialogue, but American Catholicism lacked intellectual culture, due to its failure to develop an intellectual tradition or produce its own strong class of intellectuals.\n",

"answer": " > basically the same set of skills and the same amount of schooling\n\nNo. Paramedics usually only take 2 years of school out of highschool. Nurses (Specifically RNs.... you may have meant other types of nurses which would get similar pay to paramedics) have full 4 year degrees and way more medical knowledge than a paramedic.\n\nI also wouldn't call the skill sets similar. A nurse probably couldn't do an Paramedics job (well maybe after theyd worked as an ER nurse for a bit) and theres no way a paramedic could do a nurses job. They arent all that similar.\n\nEdit: Fixed paramedic vs emt. Also yes you can become an RN via a 2 year route but thats becoming rarer.",

This prevents water from entering the lungs. Because of this laryngospasm, in the initial phase of drowning, water generally enters the stomach and very little water enters the lungs. Though laryngospasm prevents water from entering the lungs, it also interferes with breathing. In most persons, the laryngospasm relaxes some time after unconsciousness and water can then enter the lungs causing a \"wet drowning\". However, about 7–10% of people maintain this seal until cardiac arrest. This has been called \"dry drowning\", as no water enters the lungs. In forensic pathology, water in the lungs indicates that the person was still alive at the point of submersion.

876y6i | do insects get food poisoning? | [
{
"answer": "From what I understand from my microbiology class it would depend. It depends mainly on what species of bacteria is in that chicken. If the species of salmonella is able to infect the fly and cause a disease then yes the fly would be sick, but if the species of salmonella present is not adapted to attack the digestive tract of the fly then it would be as if nothing is happened to it. These adaptations would include ways to disturb the physiology and ways to counteract the inmune system. \nBeyond the species there is also the strain which is one of the reasons some people get infected with the same specie yet get more severe symptoms of the same disease. \n \nTL:DR it depends of the specie of the salmonella \n \nEdit: spelling ",
"provenance": null
},
{
"answer": "One reason insects react so differently to many toxins is because their digestive tract is alkaline in contrast to the acidic environment of the vertebrate intestines. A different pH may render some toxins less harmful and others more so. A common \"food contaminant\" for insects is *Bacillus thuringiensis*, a species of bacteria which lives in the soil (and on leaves) and basically produces a crystalline toxin that can only be dissolved in the alkaline digestive tract of insects. However, it's non-toxic to humans because the crystals pass our digestive system undissolved. This is why *B. thuringiensis* is sprayed on crops to prevent damage caused by larvae.\n TL;DR: Their digestive system makes insects vulnerable to different bacterial toxins. Yes, they can suffer from certain food poisonings.",
"provenance": null
},
{
"answer": "Yes, but often from different factors than the ones that affect humans.\n\nSalmonella is unusual \"food poisoning\" where bacteria actually *infect* the victim. Most cases of food poisoning are from toxins contained in bacteria or left behind when they die. That's why fully cooking rotten meat, for example, doesn't make it safe to eat, even though the cooking process would kill whatever bacteria might be present.\n\nA notable example is the botulism toxin which can kill, and did so often before improvements in food preservation/canning. \n\nIf affects a particular neurotransmitter used for transmitting signals between nerves. It affects the nerves humans use for muscle control causing paralysis. But other types of nerves are unaffected. Obviously an insect may have different nerves than that specific type in the human body, and likely wouldn't be affected. ",

"text": "Many insects are distasteful to predators and excrete irritants or secrete poisonous compounds that cause illness or death when ingested. Secondary metabolites obtained from plant food may also be sequestered by insects and used in the production of their own toxins. One of the more well-known examples of this is the monarch butterfly, which sequesters poison obtained from the miilkweed plant. Among the most successful insect orders employing this strategy are beetles (Coleoptera), grasshoppers (Orthoptera), and moths and butterflies (Lepidoptera). Insects also biosynthesize unique toxins, and while sequestration of toxins from food sources is claimed to be the energetically favorable strategy, this has been contested. Passion-vine associated butterflies in the tribe Heliconiini (sub-family Heliconiinae) either sequester or synthesize \"de novo\" defensive chemicals, but moths in the genus \"Zygaena\" (family Zygaenidae) have evolved the ability to either synthesize or sequester their defensive chemicals through convergence. Some coleopterans sequester secondary metabolites to be used as defensive chemicals but most biosynthesize their own \"de novo\". Anatomical structures have developed to store these substances, and some are circulated in the hemolyph and released associated with a behavior called reflex bleeding.\n",

For instance, some milkweed butterflies feed on milkweeds (\"Asclepias\") which contain the cardiac glycoside oleandrin; this makes them poisonous to most predators. These insects are often aposematically coloured and patterned. When feeding on innocuous plants, they are harmless and nutritious, but a bird that has sampled a toxic specimen even once is unlikely to risk tasting harmless specimens with the same aposematic coloration. Such acquired toxicity is not limited to insects: many groups of animals have since been shown to obtain toxic compounds through their diets, making automimicry potentially widespread. Even if toxic compounds are produced by metabolic processes with an animal, there may still be variability in the amount that animals invest in them, so scope for automimicry remains even when dietary plasticity is not involved. Whatever the mechanism, palatability may vary with age, sex, or how recently they used their supply of toxin.\n",

An early system focused only on engine noise was developed by Lotus and licensed for the 1992 Nissan Bluebird models sold in Japan. Lotus later teamed with Harman in 2009 to develop a more complete noise reduction system, including road noise, tire noise, and chassis vibrations. One benefit of active noise control is that the car can weigh less, with less sound-deadening material used, and without a heavy balance shaft in the engine. Removing the balance shaft also increases fuel efficiency. The 2013 Honda Accord used an active noise control system, as did the 2013 Lincoln luxury line and the Ford C-Max and Fusion models. Other operating data may also play a part in the DSP, data such as the engine's speed in revolutions per minute (RPM) or the car's highway speed. A multiple source reduction system may reach as much as 80% of noise removed.\n",

4v1mvv | When classical music was published in the 18th century, how did the music circulate? | [
{
"answer": "The only media available for the recording of classical music in 18th century was print, of course, and that business is essentially the same now, with a few minor changes. The printing of music parallels the printing of words, with the earliest examples being carved on wooden plates, then engraved on metal plates, which eventually changed to movable music type, and has now moved to digital. Then it would have been printed, arranged into a book, and sold to the public in music shops. The first publishers began to appear in the 18th century in the major German cities, and by the late 18th century they were also in the United States. They would often look for exclusive rights from a composer for European distribution, but Beethoven was known to have sold the \"exclusive\" rights to a single work to several competing publishers. He did the same thing with commissions and world premieres as well, but that's a different story for another time.\n\nEventually an orchestral works would make it around the continent and be performed by the local orchestras, which could be of varying quality. Some people might live too far away to go to a concert, and in any case there might only be a single performance, or at best a handful of performances. In order for more people to learn and enjoy a work, orchestral pieces were often reduced to a piano version, which were the bread-and-butter of publishers, along with solo piano works and chamber works which could be performed at home. Sometimes these reductions were arranged by the composer, but often they were done by someone else. Liszt famously transcribed all of Beethoven's Symphonies, with the Ninth Symphony requiring two pianos. These transcriptions/ reductions are still popular today. \n\nMusic was as popular with people then as it is now, so it was a major industry, and the concept of copyright went hand in hand with the printing of music. The first major copyright law was the Statute of Anne in 1709, which made the printing of music exclusive to the original publisher for 14 years, which was later amended to 21 years. This is important because while a publisher might have the exclusive rights for a while, eventually they would lose exclusivity and any publishing house could then print and sell that music (public domain). As the fame of composers grew throughout the 19th century, this was a huge windfall for publishers who could print the best-selling works of composers like Beethoven and Mozart without having to pay out royalties, making them very profitable. Today the exclusive term of copyrights has been extended greatly, due to heavy lobbying by the Disney corporation and the Gershwin estate. ",

Bach and Classical music period composers from the 1700s such as W.A. Mozart and Romantic music era composers from the 1800s such as Wagner. The most obvious of these is the development of a comprehensive music notational system which enabled composers to write out their song melodies and instrumental pieces on parchment or paper. Prior to the development of musical notation, songs and pieces had to be learned \"by ear\", from one person who knew a song to another person. This greatly limited how many people could be taught new music and how wide music could spread to other regions or countries. The development of music notation made it easier to disseminate (spread) songs and musical pieces to a larger number of people and to a wider geographic area. However the theoretical advances, particularly in regard to rhythm—the timing of notes—and polyphony—using multiple, interweaving melodies at the same time—are equally important to the development of Western music.\n",

From the 1730s elegant concert halls began to be built across the country and attendance rivalled that of the theatre, facilitating visits by figures such as Haydn, J. C. Bach and the young Mozart. The Italian style of classical music was probably first brought to Scotland by the Italian cellist and composer Lorenzo Bocchi, who travelled to Scotland in the 1720s, introducing the cello to the country and then developing settings for lowland Scots songs. He possibly had a hand in the first Scottish Opera, the pastoral \"The Gentle Shepherd\", with libretto by the makar Allan Ramsay. The extension of interest in music can be seen in the volume of musical publication, festivals, and the foundation of over 100 choral societies across the country. George III (reigned 1760–1820), and the aristocracy in general, continued to be patrons of music through the foundation of organisations like the Royal Concert of Music in 1776 and events like the Handel Festival from 1784. Outside of court patronage there were also a number of major figures, including the Scottish composer Thomas Erskine, 6th Earl of Kellie (1732–81) well known in his era, but whose work was quickly forgotten after his death and has only just begun to be reappraised.\n",

Even professional musicians rarely were familiar with music written more than a half century before their own time. In the second half of the 18th century, an awakening of interest in the history of music prompted the publication of numerous collections of older music (for example, William Boyce's \"Cathedral Music\", published around 1760-63, and Giovanni Battista Martini's \"Esemplare, ossia Saggio... di contrappunto\", published around 1774-5). Around the same time, the proliferation of pirated editions of music by popular composers (such as Haydn and Mozart) prompted respected music publishers to embark on \"oeuvres complettes,\" intended as uniform editions of the entire musical output of these composers. Unfortunately, many of these early complete works projects were never finished.\n",

"text": "During the Renaissance music era, the printing press was invented, which made it much easier to mass-produce music (which had previously been hand-copied). This helped to spread musical styles more quickly and across a larger area. During the Baroque era (1600–1750), technologies for keyboard instruments developed, which led to improvements in the designs of pipe organs and harpsichords, and the development of a new keyboard instrument in about 1700, the piano. In the Classical era (1750–1820), Beethoven added new instruments to the orchestra to create new sounds, such as the piccolo, contrabassoon, trombones, and untuned percussion in his Ninth Symphony. During the Romantic music era (c. 1810 to 1900), one of the key ways that new compositions became known to the public was by the sales of relatively inexpensive sheet music, which amateur middle class music lovers would perform at home on their piano or other instruments. In the 19th century, new instruments such as piston valve-equipped cornets, saxophones, euphoniums, and Wagner tubas were added to the orchestra. Many of the mechanical innovations developed for instruments in the 19th century, notably on the piano, brass and woodwinds continued to be used in the 20th and early 21st century.\n",

However, these riders sat far back on their horses, a precarious position for moving quickly, and the horses were held by a handler on the ground, keeping the archer free to use the bow. Thus, these archers were more a type of mounted infantry than true cavalry. The Assyrians developed cavalry in response to invasions by nomadic people from the north, such as the Cimmerians, who entered Asia Minor in the 8th century BC and took over parts of Urartu during the reign of Sargon II, approximately 721 BC. Mounted warriors such as the Scythians also had an influence on the region in the 7th century BC. By the reign of Ashurbanipal in 669 BC, the Assyrians had learned to sit forward on their horses in the classic riding position still seen today and could be said to be true light cavalry. The ancient Greeks used both light horse scouts and heavy cavalry, although not extensively, possibly due to the cost of keeping horses.\n",

The \"purified\" waste water can be evaporated, sent to a lake, river, or the ocean. Sometimes this waste water can be used for farming, but not always. The remaining chemicals and solid matter extracted from the water are dried up and used as fertiliser, compost, incinerated or simply stored in specialised waste dumps.\n\nIn the rest of the world it goes directly, or with little filtering, to the nearest river, lake or the ocean.

ak8h97 | Gorbachev and Dissolution of USSR | [
{
"answer": "I will point you to this [answer](_URL_3_) I wrote on the role of Gorbachev in the dissolution of the USSR. In essence, Gorbachev, after becoming General Secretary of the Communist Party in 1985, undertook a series of structural political and economic reforms that unleashed forces that were ultimately outside of his control. Thus while the formal dissolution of the USSR is taken to be the Supreme Soviet voting for its own abolition and the resignation of Gorbachev as Soviet president and the lowering of the Soviet flag over the Kremlin on December 25, 1991, this was largely the remnants of the Soviet government recognizing the already-existing state of the Union's dissolution (and it should be noted that some Soviet institutions, notably its [military](_URL_0_), actually persisted after this date).\n\nIn answer to your side-question - the Communist Party of the Soviet Union was stripped of its constitutional legal monopoly in March 1990, and was more or less [dissolved](_URL_1_) and outlawed following the failed August 1991 coup. Lower level elements of the party reconsituted themselves into various political parties across the former USSR, and the largest since 1993 has been the Communist Party of the Russian Federation. The CPRF has contested elections since 1993, winning a majority of deputies to the Russian legislature (Duma) in 1995, and its leader Gennady Zyuganov almost won the 1996 presidential [election](_URL_2_) against Boris Yeltsin.

Zinc deficiency can also impair absorption, transport, and metabolism of vitamin A because it is essential for the synthesis of the vitamin A transport proteins and as the cofactor in conversion of retinol to retinal. In malnourished populations, common low intakes of vitamin A and zinc increase the severity of vitamin A deficiency and lead physiological signs and symptoms of deficiency.

5985ok | Why did European firearms technology become superior to that of other continent's? | [
{
"answer": "For a very good recent book on the subject I highly recommend *The Gunpowder Age: China, Military Innovation, and the Rise of the West* by Tonio Andrade. He sums up a lot of the information and theories available as far as china goes and concludes that the main cause does seem to be a relative lack of major wars. \n\nEssentially, Chinese military technology underwent two different divergences compared to Europe. Prior to the mid 15th century Chinese gunpowder technology was on par with or better than that of the west. Chinese cannon was following European ones in the trend of longer barrels relative to bore size and the Ming army employed a larger proportion of handgunners than European armies would up until around 1500. By 1450 however the Ming had achieved a level of relative stability with no major opponents and military development stopped. Meanwhile in Europe over the next half century the \"classic\" cannon was developed and the matchlock arquebus started becoming widespread. As a result when the Portuguese first arrived in the 1520s both sides agreed that European guns and cannon were far superior.\n\nThis didn't last though, by the end of the 16th century and over the course of the 17th century warfare picked up again in china and European gun technologies were quickly adapted first by the Ming and later by the Qing as well. China developed complex drills and countermarch-style volley fire techniques even earlier than the Dutch did, and by the end of the 17th century they had defeated two Renaissance-style artillery forts. They even had plans to build their own but once the Qing had firmly established their dominance there was no longer any real need. Thus, Andrade argues, China had again reached a level of relative military parity with Europe. It was then over the course of the 18th century that again a lack of warfare combined with the relatively isolationist policies of the Qing dynasty led to a lack of military innovation and serious decline in the quality of the army leading up to a decisive defeat by the British during the Opium Wars.",

Within Morillo's framework, European weapons were more competitive due to private manufacturing whereas Chinese weapons were manufactured according to government specifications. Although generally true, Peter Lorge points out that gun specifications were widespread in China, and ironically the true gun was first developed during the Song dynasty, when guns were the exclusive enterprise of the government, suggesting that the economics of production were less influential on gun development than assumed. In contrast, less innovation occurred during the Ming dynasty when most of production was shifted to the domain of private artisans.

What’s most likely going on is exactly the same process that 4G hotspot uses, but only involving wifi.\n\nBasically the laptop is connected to the phone via some means (hotspot wifi, Bluetooth or USB cable), on a private network just between those two devices.\n\nAny traffic from the laptop destined for the inter webs hits the phone and the phone performs some address translation (NAT) before forwarding it on via the hotel wifi. As far as the hotel can see you’ve only got one device (phone) using their connection.\n\nThe phone keeps track of the data it forwards on so that when the response comes back, it knows to send it on through to the laptop.\n\nAs for the battery life - wifi uses a lot less power than 4G does because the base stations are much much closer",

},
{
"answer": "The very basics of transmitting and receiving a signal is that running current in a wire will produce a magnetic field and a changing magnetic field will induce a current in a wire. \n\nSo running current in a coil of wire or inductor will create a magnetic field. Changing the current will cause a change in the magnetic field and create a wave in the field that can be interpreted as a signal. If place any other coils of wires nearby the signal and changing magnetic field will induce a tiny current in the other coil. The direction of the current in the second coil will mirror the first coil so if you turn on and off the power 100 times per second in the first coil you can hook up a circuit to the second coil and you will see a much weaker signal being switched 100 times per second. \n\nIf you scale that up and add a relatively simple circuit that filters out all the frequencies you don't care about and only pick up and amplify a specific frequency band like around 2.4Ghz (the frequency Wi-fi use). If you slightly tweak the signal from just simply turning on and off 2.4 billion times per second you can encode information with those small variations. The receiving coil picks up those small variations and decodes it to data. \n\nEvery phone has a transmitter and a receiver. The cell towers need a huge transmitter to transfer a powerful enough signal for it to be received on your phone over a long distance but your phone also has to be able to transmit a signal so it can tell the cell tower what you want it to send. You can for example upload a 1GB movie to the cloud which your phone would then have to transmit back to the cell tower.\n\nWiFi hotspots are really nothing special it's just software that allows the phone to act like a cell tower. It constantly transmits a signal saying I'm a available network and is ready to receive any signal from connected devices. Usually it needs to dedicate one type of connection to talking with the real cell tower so it can dedicate the WiFi transmitter and receiver to acting as a hotspot while using the cellular transmitter and receiver to talking with the cell tower.",

The disadvantage of Bridge WIM is that it requires a bridge to be present at the location of interest. An advantage is that it is portable - the same system can be moved between bridges in a matter of hours. The concept of Bridge WIM is that the bridge flexes under the weight of the passing truck. Truck axle weights are found by minimizing the sum of squared differences between the theoretical and measured responses. Strain transducers are generally used to measure the bridge response but other responses are possible including deflection. Users of Bridge WIM claim similar levels of accuracy to the best of the other WIM technologies though there are few tests that provide direct comparisons. Since it was first developed, many innovations have been proposed to improve accuracy. One of the more complex is a dynamic version known as Moving Force Identification though this poses practical challenges for calibration. One of the more significant other innovations is the development of Nothing-On-Road (NOR) or Free-of-Axle-detector (FAD) systems which allow installation to take place without access to the road surface.\n",

5tsoeo | how can encryption methods be open source? | [
{
"answer": "It is a generally accepted security precept that \"The enemy knows the system.\" That is, when you are designing an encryption algorithm (or any security measure) that you assume the enemy knows its design. You assume that, eventually, an adversary will get a hold of the algorithm and therefore A) you cannot rely on the secrecy of the algorithm for security; and B) your algorithm should be secure despite general awareness of it.\n\nThe strength of encryption methods lies in the keys (and, for asymmetric methods, the inherent mathematical difficulty of reversing the encryption process).\n\nFor example, the most secure encryption method, the One Time Pad (OTP) has an extremely simplistic algorithm. ALL of the security is invested in how the key is created, used, and kept secret.",
"provenance": null
},
{
"answer": "What needs to be secret is the key (or set of keys), not the way in which the lock is built. If knowing how a lock is made can be enough to access without having the keys, it's a poor lock, no matter if its inner workings were known by legitimate access to the source code, or by reverse engineering.

"provenance": null
},
{
"answer": "We all know how a mechanical door lock works, but that doesn't mean you can just break into any lock easily. It is still much easier if you have a key.\n\nFor encryption it's kind of the same. Knowing the algorithm might give a small edge for whoever is trying to break it. Or not. Modern algorithms (e.g. AES) are actually *designed* to be completely open source and yet you'd be helpless if you don't have the actual cryptographic key used on the data that you want to decipher. Even if you have access to samples of plain text and their ciphered counterparts, you wouldn't be able to do too much.\n\nThe RSA algorithm, for example, is a quite simple mathematical operation, well known to the public for ages. But it relies on the fact that, mathematically, the inverse operation would be borderline impossible if you don't have all the variables.\n",

{
"answer": " > I was reading about the signal protocol and saw it has a github page. Doesn't this mean anyone can figure out how the encryption works and break it?\n\nAs a general rule, you should never ever give ANY credence to encryption methods that are not open source and fully examinable by you. NSA and other parties have tried to weaken encryption measures precisely by creating partially closed source encryption methods which then would have weaknesses only they would know about, and only they could exploit. Which, even if you're totally cool with NSA breaking your encryption, would still mean that there is an exploit that may eventually get out because NSA messes up for example, and some Snowden type leak reveals how to decrypt all your supposedly secure data.\n\nAny encryption method consists of essentially two parts: There is method you use. This HAS to be public, everyone HAS to know exactly how it works.\n\nThen there is the key. This key is random number sequence, typically it's about 256 bits long, sometimes even 2048 bits long. That's computer talk, but basically 256 bits long key means, you choose any number between hundred billion trillion trillion trillion trillion trillion trillion, and trillion trillion trillion trillion trillion trillion.\n\nOr basically, number that's maybe 84 or 83 decimals long.\n\nThe security comes from the fact that you need to know the exact number, every decimal of it, to encrypt or decrypt data. Guessing such a number, if you guessed trillion trillion trillion trillion trillion numbers every single nanosecond, would take roughly... Well, 31 million years to guess it right? Trillion trillion trillion trillion guesses every nanosecond is far more than anything we can currently do, and 31 million years is far longer than we can wait to decrypt something.\n\nSecure algorithm is such that you don't have any good shortcuts that are easier for decryption than trying trillion trillion trillion trillion trillion guesses every nanosecond for 31 million years. You don't know your algorithm is secure if you can't see it.\n\nA random 84 digit number could be\n\n834,485,888,921,132,283,384,723,847,928,073,987,476,456,352,956,839,445,342,342,475,324,647,232,344,664,756,578,495,4,543,436,234.

1hf3f9 | Was Philippe Pétain unjustly criticized by the new French Republic? | [
{
"answer": "It wasn't just about the fact that he had surrendered to the Germans that the French were pissed off about. Pétain and his government, shortly after the surrender, took a vote to reorganise the Third Republic into the French State, an authoritarian (and more importantly an extremely collaborationist) regime which is better known nowadays by the name of Vichy France.\n\nThis government aided in the rounding up of Jews and other \"Undesirables\", and within its colonies it actively resisted Allied forces. Fascist elements within that selfsame government then began attempting to turn France into a much more conservative country than the Third Republic had ever been. They wanted a much less secular and liberal society, preferring instead a more authoritarian catholic society. Pétain himself supported the movement, but said he didn't like the name it was using, which was \"National Revolution.\"\n\nCensorship was imposed within France, and freedom of speech and thought repressed with the reinstatement of \"Felony of Opinion\". Pétain himself said that: \"The new France will be a social hierarchy... rejecting the false idea of the natural equality of men\".\n\nPétain went on to allow the creation of a Vichy organised militia known as the \"Milice\" to suppress the Maquis, in particular its Communist factions.\n\nAfter the occupation of southern France, Pétain became a mere figurehead for what was no longer even a pretense of an independent government in Vichy. When the liberation of France came about in the September of 1944, the Vichy government was relocated to Germany, where it became a government in exile. By this point however, Pétain refused to take part in it any longer, and the running of it was taken over by Fernand de Brinon.\n\nOn the 26th of April 1945 Pétain returned to France via Switzerland to face his accusers. The trial ran from the 23rd of July to the 15th of August 1945, the main charge being treason.\n\n\n\nIn short, while he may not have merited a death sentence (Which was only not carried out due to his age), Pétain was far from an innocent man. He had run an authoritarian, collaborationist regime that had sought to overturn a lot of the values that the French have held dear since their revolution in 1789. He was not on trial for the surrender, but for everything that came after it.",

After Aristide was removed from the country in a US registered plane, Philippe and his army put down their guns in favor of the UN peacekeeping force. He has also been accused of drug dealing, and Aristide supporter group claim he is a covert CIA spy, recruited by an agent in Haiti to start the coup.

3849rg | How come in Physics we can round off numbers willy nilly? | [
{
"answer": "Someone asked a very similar question the other day and it got a lot of good answers, so I'd recommend you [read those answers](_URL_0_) (I linked directly to my favorite response). But here's my quick take on it. Numbers in math are ideal. If I ask you to solve the equation x^2 = 2, the answer is exactly sqrt(2), even though that has an infinite number of decimals - it's 1.41421356... where the ... means it keeps going on forever. If you round, it's usually because you don't have enough space for the full answer (in the case of sqrt(2), it's because you don't have an infinitely long sheet of paper).\n\nIn physics or other experimental sciences, you can only ever measure a quantity to some finite accuracy. So if a measurement you make is only accurate to the third decimal place, then if it comes out with the number 1.414, you can't just write 1.4140000, because the real answer might be 1.41414131, or 1.41402492, or anything else. When you manipulate that number - multiplying it by something else, for instance - then you can only keep up to 3 decimal places, because your measurement was only ever good for that many to begin with, and it wouldn't be honest to pretend that you can get a more accurate answer.",
"provenance": null
},
{
"answer": "Your reported answer in sciences should reflect the accuracy to which you know it. If your measurements allow you only 3 digits of accuracy, then so be it. For instance, a 12-inch ruler you may have lying around the house probably has one side for centimeters, perhaps with millimeter hashes as well. It would not make sense for you to be able to measure a length with that ruler and report any value with accuracy beyond millimeters.",

{
"answer": "If I wanted to know the average acceleration of gravity, say, at the surface of the Earth, I know the radius is about 6,371 km, the mass is about 5.972e24 kg, and G is 6.67384e-11 m^3 / (kg s^2 ).\n\nI would use all of those numbers as they are, then round the result to four significant digits because that's the least precise of my initial numbers. Instead of 9.819296623, which is what Google's calculator gives me, I use 9.819 m/s^2 .\n\nIf I just wanted a ballpark figure I'd use 6400, 6.0e24, and 6.7e-11, and I'd get 9.814, but since I only had two significant digits in my numbers, I could only claim to have gotten 9.8 m/s^2 .\n\nBut sometimes people have to be very precise in physics. Quantum Electrodynamics is famously [\"the most precisely tested theory in the history of science\"](_URL_0_):\n\n > Experimental tests of QED measure small shifts, but to an absurd number of decimal places.

{
"answer": "When measuring things in the real world, there is uncertainty related to the measurement. When using a ruler, I may often get an answer 0.1 mm wrong, sometimes 0.2 mm wrong and occasionally 0.3 mm wrong, for example. That's why physicists usually specify their results of the form foo ± bar. For example, if I measured a length at 425.1735 mm, and had studied how accurate my ruler is and found the error to be less than 0.257 mm 68% of the time (68% may seem a bit arbitrary, but it is based on properties of the [normal distribution](_URL_0_), the most common shape errors take), I would quote the result as ´425.1735 mm ± 0.257 mm´. The last number is the [standard deviation](_URL_2_), and indicates the typical size of errors.\n\nWhen specifying the uncertainty explicitly, the number of digits you quote is mostly a question of convenience. Since my measurement is typically off by about 0.26 mm, I can safely drop the last few digits of my result without losing much real accuracy. For example, if I drop the last two digits I would be moving 0.0035 mm away from the most likely answer, effectively introducing an extra error terms. Uncorrelated errors add in quadrature, so this would bring the total standard deviation up to sqrt((0.257 mm)²+(0.0035 mm)²) = 0.257024 mm, which is practically the same. So we can safely drop a few digits.\n\nWe can use our knowledge of the uncertainty to quantify how [statistically significant](_URL_1_) a change in any given digit would be. A change in the last digit, for example from 425.1735 mm to 425.1730 mm, is a change of -0.0005 mm, which is 514 times less than the standard deviation. We usually consider a change to be statistically significant if it is at least two times lager than the standard deviation, so the last digit is definitely not significant. The same holds for the next three digits (51, 5 and 0.5 times less than the uncertainty). So we are left with 4 significant digits: 425.1 mm.\n\nIf we know that we only quote the significant digits, then we can to some extent make do without specifying the uncertainty explicitly. So instead of writing 425.174 mm ± 0.257 mm, I could simply write 425.1 mm. This is much more compact and less tedious to deal with. But it is also less informative, as one now suddenly has only a vague idea of the standard deviation (to within a factor of 10).\n\nI work in physics (astronomy to be precise) and I rarely use the [significant figures](_URL_3_) framework for calculating. I and my colleagues use [full error propagation](_URL_4_) instead.\n\nTLDR: In physics there is uncertainty which needs to be indicated somehow. This can either be done by explicitly giving the standard deviation, or by only quoting the significant digits. If you don't specify the uncertainty explicitly, it will be assumed that all your digits are significant. That is why people bug you about using too many digits.",
"provenance": null
},
{
"answer": "It might be better to reword the question as, \"when doing physics problems it is possible to generate increasingly long series of decimal points through math operations. Which ones should be kept?\".\n\nAny measurement starts with an error. Even if I'm very accurate measuring length to A +/- A/10,000 if I'm taking that result to powers or adding it to something less accurate I have to carry the resulting error along in my calculations. \n\nLet's say I'm predicting the expected temperature of my pool based on solar heating. I can estimate the volume fairly accurately but not the loss due to radiant heating in the pumps or the direct amount of solar radiance absorbed. If I say \"temperature delta is heat input divided by volume factor minus losses\" terms with high errors could dominate. The error is included in the calculations. You have to carry them along as fractions of the original values and perform all the same operations on the error. The calculated total error provides guidance about how many decimal places to keep.",

A simple and commonly used way to force such numbers into a desired range is to apply the modulo operator; that is, to divide them by the size of the range and take the remainder. However, the need in a Fisher–Yates shuffle to generate random numbers in every range from 0–1 to 0–\"n\" pretty much guarantees that some of these ranges will not evenly divide the natural range of the random number generator.

Although Hawking touches on the origin of the universe, the physics of black holes and some of his other favorite topics, his main concern in this book is not physics. It's humanity and its collective future ... Focusing his attention in the book on three related questions — the future of our planet, colonization of other planets, and the rise of artificial intelligence — he charts his strategy to save us from ourselves ... Only science, Hawking argues, can save us from our mistakes ... Hawking believes that humanity's evolutionary mission is to spread through the galaxy as a sort of cosmic gardener, sowing life along the way.

He was initially disappointed to find that he had been assigned Dennis William Sciama, one of the founders of modern cosmology, as a supervisor rather than noted Yorkshire astronomer Fred Hoyle, and he found his training in mathematics inadequate for work in general relativity and cosmology. After being diagnosed with motor neurone disease, Hawking fell into a depressionthough his doctors advised that he continue with his studies, he felt there was little point. His disease progressed more slowly than doctors had predicted. Although Hawking had difficulty walking unsupported, and his speech was almost unintelligible, an initial diagnosis that he had only two years to live proved unfounded. With Sciama's encouragement, he returned to his work. Hawking started developing a reputation for brilliance and brashness when he publicly challenged the work of Fred Hoyle and his student Jayant Narlikar at a lecture in June 1964.\n",

It is centered on the speculated and potential eruption of the volcanic caldera of Yellowstone National Park. Its tagline is \"Scientists know it as the deadliest volcano on Earth. You know it...as Yellowstone.\"\n",

"text": "The loosely defined term \"supervolcano\" has been used to describe volcanic fields that produce exceptionally large volcanic eruptions. Thus defined, the Yellowstone Supervolcano is the volcanic field which produced the latest three supereruptions from the Yellowstone hotspot; it also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake 174,000 years ago. The three supereruptions occurred 2.1 million, 1.3 million, and approximately 630,000 years ago, forming the Island Park Caldera, the Henry's Fork Caldera, and Yellowstone calderas, respectively. The Island Park Caldera supereruption (2.1 million years ago), which produced the Huckleberry Ridge Tuff, was the largest, and produced 2,500 times as much ash as the 1980 Mount St. Helens eruption. The next biggest supereruption formed the Yellowstone Caldera (~ 630,000 years ago) and produced the Lava Creek Tuff. The Henry's Fork Caldera (1.2 million years ago) produced the smaller Mesa Falls Tuff, but is the only caldera from the Snake River Plain-Yellowstone hotspot that is plainly visible today.\n",

"text": "In 2005, a BBC/Discovery docudrama entitled Supervolcano was released on cable television. The drama imagines the reaction of the Yellowstone Volcano Observatory to a super eruption at the Yellowstone Caldera. Producer Ailsa Orr credits YVO scientists as inspiration for the film's three primary characters. The YVO Scientist-in-Charge reflected on the hype associated with volcanism at Yellowstone in a 2005 magazine article.\n",

Rick and Ken argue about Ken's appearance on TV, which Rick passes off as Ken creating a mass panic in order to sell his book. Their argument is interrupted by Fiona Lieberman, Rick's wife and Ken's sister. She reflects that Rick is cautious of what he says in public due to the press convincing people Yellowstone was going to erupt due to the discovery of a bulge in Yellowstone Lake some years before.\n",
