hat happens to the body fat when you are losing it due to diet or sports?
I mean, the fat can't just disappear, or can it? :D

why does it seem more offensive to mimic a chinese accent rather than a british accent?
I see people doing british accents all the time but no chinese accents.

A Chinese accent where English is spoken *well* is considerably less offensive than a Chinese accent where it is spoken poorly, which often comes off as mockery. Similarly, Chinese accents from Hong Kong, Singapore and Malaysia seem to be viewed as much less offensive (e.g. saying 'lah' at the end of sentences is rarely, if ever, seen as racist). These places coincide with places where English is much more commonly spoken.\n\nIf you think about which accents seem racist and which do not, it seems that, generally speaking, English accents from English-speaking countries are not seen as racist or seen as less racist than English accents from non-English speaking countries. So an Indian accent seems less offensive than a Chinese one, and Jamaican accents and Nigerian accents are often imitated.", "Don't forget, mocking can go both ways. The Chinese probably laugh themselves stupid at English. The Brits can and do laugh at some aspects of US accents. \n\nIt's the context that makes things racist.", "English isn't the native language of China, but it is for Britain. Speaking Chinese with a Chinese accent wouldn't be racist. But more importantly, there is a long history of speaking English in an Asian accent as a method of putting down the Asian culture and people (look at the humor from the late 1800's up until the mid 1900's for examples). It's still a touchy subject. " ] }

why do humans instinctively react to objects moving quickly towards them by closing their eyes or looking away?

This is how the Taliban is still in power in parts of Afghanistan, because they do make efforts to keep the people fed, employed and somewhat protected. \n \nISIS has been well funded, and this is a major reason why they're still surviving. They have hijacked oil fields and sell that oil on the black market. They are also secretly funded through unknown supporters, likely to be Saudis who share their religious ideals and support the growth of Salafism/Wahhabism in the Middle East.\n\nThe long term strategy of the Obama admin, from my understanding, was that they would eventually run out of funds, and once they did that they would begin to see fractures in the morale of their fighters, and a general diminishing of local support as they fail to keep their promises to the people in their \"caliphate\".\n\nSo airstrikes have been targeting their shipments of oil and illicit funds, cutting off their supplies which has led to a [reduction in their recruitment efforts and an increase in defections.](_URL_0_)\n\n", "Because (as history has taught us) it's being fueled on both sides by essentially the same entity.", "Because the US has spent the better part of two decades bombing people.

As a matter of fact USA supports rebels who technically fight alongside ISIS. Also it's well known that Saudi Arabia, a major US ally, who receives weapons and money from the USA, most likely supports and funds ISIS. Russia is technically supporting groups who fight ISIS but only because they're supporting the opposite side of the war in Syria that the US does. This is likely because they want their own pipeline through Syria to the Baltic Sea so they can control oil exports. Both oil pipelines are pending projects and one can see the ally relationships in neighboring countries and understand both US and Russian plans for the pipeline.

It is not possible to shoot or bomb out an ideology; the only way to eradicate or push it into irrelevancy takes time and education and good governance. It is especially difficult with an ideology that is culturally deep-rooted and aligned with a religion - ISIS claims to be the new Caliphate and demands that all Muslims are required to support it and move there. \n\nThe second explanation is the core of ISIS were Iraqi Sunnis who found themselves out of power and being killed when the Shia regained power after Saddam. They had trained military officers who could direct the cannon fodder fighters to capture and hold large swathes of territory across the borders of at least 3 countries. The civilian population initially sided with them due to the bad governance they were facing and by the time they realized their mistake, ISIS was deeply embedded in heavily populated areas and killing civilians wholesale to suppress dissent.

Some of these militias can be \"homegrown\" and just claim to be isis as well. Now how do we target these numerous, smaller militias? While information intercept can lead us to the larger threats, there are still hundreds of smaller groups that claim alliance to isis which you cannot track because they do not communicate. As well, once targeted, they will blend in with their neighboring civilians (sometimes in safe spots like mosques, hospitals, schools, etc) so the threat cannot be eliminated. The \"pro\" to all this is (as it IS a con within itself) that as multiple, smaller militias they are not organized/coordinated enough to be of major threat. Most of our domestic, terrorist attacks are people within the US claiming Isis alliance and not those from the Middle East entering the US to commit an attack. There are other reasons as well, but this is a major contributing factor.\n\nEdit: Source - took a political science course last semester and asked the same question.

These types of organizations are bound by a similar ideological belief, which makes waging traditional war against them incredibly difficult, if not impossible. \n\nWhile a lot of responses here are partially right, I have to say that the situations in the Middle East and North Africa are a lot more complicated than starving them of money, supporters, leaders, or having a strong military presence on the ground. If things were that simple, we would have solved the issues in the Bush years, or during Obama's troop surge and increased drone strikes.\n\nBut, why is ISIS so hard to defeat? Because ISIS can be boiled down to a combination of fringe religious ideology, long-standing cultural identity that goes back hundreds to thousands of years that Western powers tend to choose not to fully understand, and the economic + governmental damage Western powers initially caused dating back to the raping and pillaging of the area back during the the era of global European colonialism (that this region still hasn't recovered from).\n\nQuick Edit: I see a lot of people throwing Vietnam in as a parallel.

Are they leftover strands of the military that Saddam and Al-Quida (sp?) lead?", "Because the only ones fighting ISIS with boots on the ground are Iraqi soldiers and some tribes up north. One of the major rules in any war is, you can bomb, you can use drones, \nbut without BOOTS on the GROUND you will not take anything. They are essentially the backbone. They claim territory. If in the future we are lucky enough to see a US and Russian coalition going there with boots on the ground, tanks, backed up by airstrikes, it would take a few months to eradicate them. That is if RU and US follow a strict no prisoner-shoot on sight policy which in case of ISIS they most definately should.", "Lots of great information here/below but from a very fundamental perspective it boils down to fighting an ideology rather than an army is a war no one has ever won.

Not many fighters with worse weapons. \n\nThe gov just protects their area, Rebels are fighting but making no progress. Just after the Kurdish force joined there was some progress and other units followed like Iraqi troops and Rebels.\n\n ", "Radical ideology is really what we are fighting here and every time collateral damage occurs it undermines our ability to fight radical ideas further. It actually helps spread the ideas. It's like carpet bombing a forest fire. \n\nFor some context, I was in Iraq in 2009. As you would imagine, most the destruction had already taken place by then. So I got to see the aftermath of our invasion. There was no open resistance when I was there. No one tried to fight us. They just watched us roll down the roads for the most part. \n\nNow imagine if you were say, 5 years old, and your home was destroyed by a bomb. Maybe someone from your family was killed.

No matter how bad someone tells you it was before, you can never feel like it could be any worse than it is now. \n\n**The enemy we are fighting now, is an enemy we created**. \n\nIt's no longer an abstract idea. The kids that grew up amongst the rubble that we prepared for them are now fighting age. Radical ideology spreads through the oppressed like a plague and those people will forever fight. It's not that I sympathize with them. I just understand the anger. Isis is just one of the many names that this ideology has fallen under(Boko Haram, Mujahadeen, Janjaweed, Al Qaeda) and it's not the only kind of radical ideology. \n\nThe difference is the amount of time, space, and motivation that's been necessary to breed. All of this is compounded by hostiles never being a uniformed enemy. They always wear civilian clothing. \n\n\nHere are some ~~pics~~ really incredible photos taken by a soldier in my platoon.

For each of those years we had to analyze the stability of a particular country. My country was the small island country of Mauritius, that sits 1500 miles off the SE coast of Africa. One of the things we needed to keep up on was the possibility of terrorist attacks. Through my research I found that the possibility of a terrorist attack on Mauritius is close to zero. Reason being, 1) There's not a terrorist organization on earth that has nautical capability passed 1,500 miles. 2.)There's no natural resources for them to exploit. 3) Mauritius has more police officers on their island per 1000 residents than the United States does, and they also have a new naval ship donated to them by the Indian Military. To put it in a nutshell, Mauritius's doesn't have easily traversed borders, and they're too stable of a country for a terrorist attach. Meaning what? ISIS can't really do shit. If you take a look at all of the countries, or territory ISIS has \"control\" over, or has had control over, you'll that find these countries haven't had unstable governments for decades. They can only take over dystopian countries because militarily, its an insult to any military to even consider them one. What real military has to cut off 21 heads on social media to convince people they're powerful? None of them. ISIS are just a bunch of bandit murderers taking advantage of the medias need to sensationalize the minuscule into something story worthy.

There are 3 Major Strongholds That have been essentially Surrounded by Strong Enemies. Airstrikes alone can only do so much.\n\n1 is Raqqa Its the Capital City of the Evil ISIS People. Raqqa has been completely Cut off from the outside by the Kurds. The Kurds cannot advance yet because Turkey does not like the Kurds. ISIS has many supporters in turkey and if the kurds Advance towards Raqqa the Kurds might get bombed by Turkey and raqqa would not be Surrounded anymore and ISIS would be free.\n\n2 Dioz El Zur Is a city south of Raqqa the Regular Syrian Army is fighting them there. But the Syrian army is stretched thin and Assad has strategic reasons to not expend resources and defeat ISIS there. ISIS is fighting everybody that Assad is fighting too. So assad waits until all parties have exhausted themselfs to swoop in later....at least that is the plan. And that is why in Dioz el Zur there wont be any decisive victory coming soon.\n\n3 Mossul, by far the largest stronghold of ISIS, the Kurds and the Iraqi Army have surrounded the city. The kurds fearing Turkish intervention and the Iraqi army...oh boy...well they are not very good at fighting i am afraid. They want to not damage the city too badly so they can use it later. So advances if any are very slow.\n\nIn Summary ISIS still exists but is defeated, even though a victory will still take a few months ISIS does not have the means to break any siege, their command structure is in shambles, either through targeted assassinations of leaders by the US or by filling their bags with (literal) gold and moving to nations that offer rich terrorists harbor. They cannot mount anymore offensives and after the atrocities they have committed can not expect clemency from the warring parties. So they have no reason to call it quits either. But even after a military victory the Idiology of ISIS has found many supporters in the middle east and among the muslim population in Europe. Terrorist attacks will continue until the people dont like ISIS anymore. Solution for this problem are not clear. Many hope that European freedom and liberty will make people not want to be terrorists and kill people. While others believe that if that is not happening that the muslims must leave. In any case ISIS is the worst thing that has happend to the middle east and to Islam since the crusades. Nobody can clearly predict what will happen, but everyone who studied the situation knows that the situation will not get better.", "ISIS is no longer just an \"organization\" it has become a way of thinking, ideology.

That's only half the battle though.", "I'm really going to try to tackle this, *like I'm 5*. Inherently many of the nuanced points might not be conveyed well.\n\n**School Yard Example:**\n\nEveryone is out a recess and many of the kids are eating snacks, but Billy and his close friends don't have any snacks. Billy and his friends are playing in the sandpit grumbling about being hungry. Eventually, \n\nBilly gets so fed up about this that he decides to grab a toy, and throw it at a kid with a snack. Billy tells his friends that if you join me, I'll give you part of my snacks, whatever that may be. Some of them like the sound of that, some of them don't. Billy changes his tone, this time threatening, he says help me throw toys at the kids with snacks, or I'll throw toys at you.\n\nNow everyone in the sandpit is on board, or at least isn't going to oppose it. Billy takes his toy airplane, and he throws it at George. \"OUCH\", George yells. George and his friends are angry. They have more energy because they aren't hungry, and being frank, George has more friends. George rallies his friends together, they come over to the sand pit, and they take all of the toys away. They warn that if they act up again things will get worse.\n\nFrom Billy's point of view, his still starving, and now some \"meany head\" just came in and took something he really enjoyed and cared about. As you can imagine, Billy isn't going to sit there and take this, now he's more angry. He's now gossiping with all of his friends about how much George and everyone else sucks, and finally he starts cooking up a new plan to get back at them.\n\nBilly acts up again, he walks over, throws George's sandwich on the ground and stomps all over it whilst yelling about how this is justified and George is mean. Well, this doesn't go over so well, George winds up, and punches Billy square in the face. After a quick squabble George, having more friends to back him up, wins and Billy goes away. Billy and his friends are still hungry, now they don't have toys so their frustrated, and Billy has been punched in the face so they have something specific to use as proof that George and his friends are bad people; imagine how angry that gossip must be.\n\n**Afterwards**\n\nThis example highlights that while Billy and George are fighting with increased vigor, no one is addressing the real issue: Billy is hungry. In fact George, in his frustration, just keeps making things worse when he shows up. This example highlighted a few things:\n\n* To end extremism you need to tackle the root grievances. If you don't, similar organizations and thoughts will just keep arising. If Billy is hungry, punching him won't fix that.\n* Many are coerced into fighting, or into not speaking out against it. There is usually a dogmatic inner group of dedicated radicals that must be dealt with by force, but as you get further from them people are less devoted. At the fringes many are only joining the fight because they're getting paid, and couldn't support their family otherwise.\n* Playing into the story of extremists usually helps them significantly with recruitment. When George punched Billy, now all of Billy's friends are all hyped up and ready to help out. A real life example of this was the [Abu Ghraib Prison](_URL_0_).\n\nThis example also fails to communicate a few things:\n\n* Extremism isn't solely comprised of Islamist extremism.\n* There are many more problems besides hunger, but poverty is a huge one.\n* Extremist tend to recruit young males most effectively, this provides them with an immediate outlet for adventure and excitement, a cause, a chance to have much more influence than they probably otherwise would have. Many counter violent extremism (in the development space at least) aim at young people to catch them at this key stage.\nThis example doesn't set any historical context.\n\n**End**\n\nUltimately this still leaves out a lot of what's at play here, but I still think it's useful to explain whats going on. Hopefully if anyone actually reads this, people will comment to help me fill in the situation more wholly. yet if there was one take away here, it's that we keep trying to fight the people instead of the actual problem. Even if we did magically \"defeat ISIS\" tomorrow, a new organization would rise with the same anger and concerns as the one before it. Sure it would have different features and iconic components, but it would more or less be very similar in what drives it and makes it function. That's where Developmental Assistance comes in, to address the root grievances and stop the situations perpetuating these organizations.\n", "**TL;DR: To almost every actor in the region, they are more useful alive than dead**\n\nTo understand the answer, we must first understand some significant points:\n\n1) Any answer that says \"x is the main problem\" is super simplistic. It may have part of a problem, but, like the rest of the grown up problems of the world, a complex issue like ISIS/terrorism cannot be reduced to a single point.\n\n2) There are always more questions than clear answers. This is a significant problem when lives are at stake, but I do believe that, given the research over the last century or so, we have a fairly reasonable idea.\n\nThe single sentence answer, which necessarily needs to be broken down into a thousand different pieces, is as follows:\n\n**The vast majority of terrorism in the last two centuries has been committed due to the political interaction of identity and the state**\n\nTo understand this completely, we have to understand the concept of the nation. Most people around the world feel nationality in at least three levels:\n\n1) Lowest level - The state as a function of nation\n2) Mid level - the Ethnic group as a nation \n3) Highest level - Religious group as a nation\n\nThere are other \"nations\" as well, but these three are the most common. Now, the marriage of Westphalian peace that designated (theoretically) standard borders and the increased centralization and power of governments, the challenge became to somehow synthesize these three. The idea of a political \"people\" is born. The most cohesive state, then, was one where people shared all three national identities. The least cohesive state was one that had neither 2nd or 3rd, and thus even the function of the state as a nation fall into peril. \n\nFollowing the peace at Westphalia, Europe was consumed by violence which was primarily nationalistic violence. Between revolutions, revolts, genocides, and ethnic cleansing, Europe was a blood bath from 1648 to 1945. When one portion of Europe reached stability, another portion was lit ablaze by nationalist politics.\n\nThe Arab world never had that moment. Even after the fall of colonial powers in the Arab world, the cold war politics of the US and Russia necessitated that the Middle East, a key region in the cold war, could not suffer the instability like that of Europe after Westphalia. So strong men were put in place who clamped down on the political negotiations which are required for the long term stability of a state which functions as a nation (A nation state).\n\nNow, fast forward to today. The strong men of the Arab world collapse (Saddam and Yemen forcefully, Mubarak, Qadhafi, and Assad by public pressure). This unleashes a huge tide of suppressed nationalist politics, which is always, always, always both disastrously bloody and excessively violent. Add in the Western exploitation of Pan-Islamism for combating the Soviet Union in Afghanistan, which leads to 9/11 (once the Soviets were defeated in Afghanistan, Al Qaeda and other mujahideen groups focused on two other Empires encroaching on \"Muslim sovereignty,\" the US (Iraq, Palestine, the Gulf) and Russia (Chechnya)).\n\nNow, how does this lead to terrorism against the West? \n\n1. The West obviously has a terrible reputation in the Middle East, going back two centuries. But **America's** bad reputation starts in the 50s, with the opposition of the United States to Mossadeq, the United States propping up of Israel, the US opposition to Nasser (who was extremely popular in the Arab world), and the United States support of dictators. Now, add the Iraq sanctions and the Iraq War II, and you get just flaming hatred for the West.\n\n2. That hatred is used by the Pan-Islamists in fighting the US wherever it has presence in the Muslim world. But, for nationalists like ISIS, it has a much more sinister use.\n\n3. Attacking \"the West\" creates legitimacy for ISIS. Due to the involvement of the US during the cold war (and after) in the Middle East, hatred for the West is immense in the Arab world. Attacks against the \"oppressors,\" then, serves as a legitimizing tool in a fight where manpower is at a premium. \n\n4. This leads us to ISIS of today. It is a nationalist movement which gains legitimacy for showing how it is fighting the historic oppressors by bringing the war to them. \"We are doing to them what they have been doing to us\" is the line they use consistently in their recruitment material. The goal, though, is to swell their ranks LOCALLY, not to actually harm the west in any way. No one seriously thinks ISIS is creating any real national security risk for Western nation -- not ISIS, and not Western nations. This is just a really great propaganda tool for them. \n\nNow, given all the above, why is ISIS so difficult to defeat:\n\nThe reason why ISIS in particular has not been defeated, is, primarily power politics:\n\n**1) Power politics between nations always supersedes the threat of terrorist organizations**\n\n**2) ISIS is not the main concern of Middle Eastern nations. The power imbalance and vacuum between Iran, the Gulf allies, and Turkey is**\n\n**3) The Syrian civil war adds to those complications significantly**\n\n**4) Nations are more focused on fighting for power balance than against ISIS**\n\n**5) In managing the power politics in the Middle East, ISIS is actually useful for most if not all powers in the area**\n\nLet's give a couple examples:\n\n1) Turkey: \n\nTurkey was fighting Assad in Syria, but the Kurds to the north were a serious threat to their territorial integrity. As such, they helped ISIS fight the kurds to the north as well. But to assuage Western powers, they made a show of fighting ISIS as well.\n\n2) Saudi:\n\nSaudi is actively funding ISIS to push back Iranian allied Syria and Iraq and force Iran into a perpetual war with ISIS. This is because the Gulf allies are terrified of being surrounded by the Iranian led alliance of Iran, Syria, Iraq, and Yemen. It therefore needs to ally with groups like ISIS and Al Qaeda to force Iran into perpetual war and keep it from cementing that alliance.\n\n3) Iran:\n\nIran wants to fight ISIS. It really does. It's probably the most active in fighting ISIS. But it can't make a death blow to ISIS yet, because of Iraq and Russia.\n\n4) Russia:\n\nISIS is extremely useful to Russia. As long as ISIS remains a force, it provides Russia diplomatic cover for its activities in support of Assad as long as it can shove a few bombs towards ISIS and say that it's there for terrorism. Therefore, Russia NEEDS ISIS to assist its ally Assad.\n\n5) Iraq:\n\nIraq is a key ally to Iran, and ISIS is an existential threat to the Shia regime there. BUT airpower is extremely limited in efficacy, Iraq doesn't have a strong enough ground force to take ISIS on itself, the US won't allow the only other real enemy of ISIS (Iran) into Iraq en masse to defeat ISIS, and the other members of the anti-ISIS coalition see ISIS as to useful to destroy just yet\n\n6) The US and the Western Allies:\n\nThis is where things get really fun. The West wants to defeat ISIS. But to do so would effectively hand Syria to Russia\\ and Iraq to Iran, making a giant power block from Iran to Syria and Yemen to the south. So it wants to use Iraqi ground forces to force ISIS into Syria and let them fight it out in the Syrian civil war, while putting diplo pressure on Iraq to break its ties with Iran and try to isolate Iran diplomatically. \n\nThe key to defeating ISIS:\n\n1) End the Syrian civil war\n2) Bring about political reproachment in Iraq and Yemen\n3) The powers in the area will crush ISIS in a day\n\nEdit: All the above is an interpretation consistent with the theories of the school of realism in international relations. For more information about the realist school, read \"The Man, the State, and War\" by Kenneth Waltz, \"Theory of International Politics,\" by Waltz again. For my favorite sub school, offensive realism, read \"Tragedy of Great Power Politics\" by John Mearsheimer. \n\nEdit: Thank you for the gold kind stranger!", "The more you fight them, the more fodder for recruitment they have.\n\nTerror is the end goal. Our reaction is their fuel. The more we fight them, the less they grow.", "We're fighting ourselves, that's why. The middle East is the CIA, (ISIS, Al Qaeda), vs the Pentagon. That's why it's called \"theater\". It's a show put on by the 'military industrial complex' Eisenhower warned us about in order to milk us dry. It's a big drug dealing, gun running, pedo ring using our military bases to smuggle contraband and sex slaves around the world while avoiding customs. Heroin from Vietnam was smuggled in the coffins of dead soldiers for cryin' out loud. Of course these psychos don't wanna shut it down and it won't stop until we stop'em. ", "so many bad answers here. The primary reason is that all the big entities are not actually fighting them on the ground. The US, and to a lesser extent other western powers, will bomb them from time to time. But due to concerns about collateral damage, they just don't carpet bomb an ISIS town. It's just a small air strike here and a small air strike there. \n\nTo actually defeat them you need ground forces. None of the major forces - including the Syrian army - are fighting ISIS on the ground. The biggest one doing so is the Iraqi army, which is in the process of pushing them out of Mosul. But again, they don't want to just turn their own city into rubble and don't want to kill their own civilians trapped there. So it is very slow and methodical fighting.\n\nISIS has been losing ground for a long time. But this mix of no large armies fighting them + slow advances so as not to kill civilians = slow progress. ", "We dont want to destroy ISIS rather prop them up and make them an enemy so we can keep building bombs and weapons. The Middle East was more stable before the US invaded. When you take people out of power like Saddam it creates a vacuum and more chaos", "A lot of good answers. One fact that seems to be missing is the logistics of where the strongholds are. ISIS and others do not just sit in a camp in the middle of nowhere in the desert. They are smart enough to realize that the US won't go bombing recklessly heavily populated areas. (Yes, we have killed civilians even though it has not been admitted). Mosul was taken by ISIS and the only way to flush them out is one by one on the ground unless you want to carpet bomb the whole city and deal with the backlash of killing thousands of innocents. This approach would just breed more hate to us and we end up back at square one with a new leader emerging and starting another Islamic group and naming it something different. We will go through dozens of Islamic groups like ISIS in our lifetime. In ten years it could cycle back to Al Qaeda or the Taliban. Most likely, a current student of Al-Baghdadi will break off on his own and create an even more radical group in the foothills of Iraq.", "Religion and ideological values set a foundation but ISIS is unique in how it has grown beyond just \"cult status.\" The reasons for this are vast and highly connected to their financial funding, social media presence, the global awareness of the group, and ability to recruit across borders. \n\nWe could talk about the drive to create a caliphate - essentially an Islamic State as the name ISIS would suggest. This has grounding in the Koran though no doubt Islamic scholars always debate the details just like we see in other major religions. This is part of the reasons for having different denominations and sects. Religion is a fluid thing and never concrete, which is why they can persist for extended periods of time. All this said, I find the religious aspect to be to simple to explain the power of ISIS. \n\nI should add I work in Compliance (AML and terrorist financing are my focus). I think the financial and media driven elements paint a larger story of how ISIS continues to exist so well. \n\nMuch of ISIS recruitment is done online and in places where people are at their lowest and most susceptible to promises of a better life - or promises of providing some better standing with a higher power. Jails throughout the EU are an example breeding ground. The uncomfortable thing about this is it is not a unique strategy - every religion or life changing ideological organization (like AA) provide similar services. We consider most religious visitors or organizations dedicated to, at least, social norming such as with AA when the goal is to convert alcoholics to non-alcohol driven lifestyles. Islam is not exempt from this and is generally accepted through much of the word - and heavily through policy in countries under Islamic law and EU countries as well (which some consider to be a contributing factor to ISIS attacks in Belgium and France for example). \n\nThe recruitment is critical because it not only provides a \"body,\" but everything that body can provide. While some become fighters and even smaller numbers suicide bombers or executioners, most become just a part of the ISIS nation. The soldiers need food, places to stay, work and money to fund equipment, etc. Some of these people involved in the ISIS network may be by force - as may be the case with many business owners forced to pay money to ISIS just to exist. They also own and receive money from much of the oil flowing out of the Middle East, adding a serious amount of revenue into their coffers. \n\nIn order for the caliphate to work, there needs to be a functional economy. While it's disputable to what extent ISIS really operates a standalone economy - I have seen examples of a possible currency created for ISIS members used to pay for goods and services. I have also heard of members being paid salaries - for fighters this is extra concerning as no doubt mercenary types may not care for the religious experience, but more for the financial opportunity. Recruitment of foreigners often begins with some coercion of having basic needs met with money, housing, a social group, etc. Situations like this help show how ISIS is not just a religious institution, as even the non-religious can benefit if they are valuable enough - and everyone is valuable, even if you are just a body a bomb can be strapped too. \n\nPulling from my work experiences evaluation merchant relationships with generally large corporations of the world, I can tell you screening measures are often lax and to some extent arbitrary. It is made worse by organizations wanting to save money so they do the bare minimum required to remain \"compliant.\" This has meant half-assing documentation required to do business with new merchants, for example. \n\nStill, when the vetting system works correctly, it is still difficult. The key to defeating ISIS is to remove their money flows - but this is made difficult to do as they do not just use traditional banking systems but also Islamic banks, hawala exchanges, cryptocurrencies, etc. All of these things paired with organizational layering on an international level helps ISIS breed the money it needs and, importantly, keeping it available and accessible when needed with little concern for being discovered as associated with ISIS. \n\nWhen it comes to financing ISIS, it can be difficult to determine just when money is being used by or for ISIS. Most money is not being sent via PayPal to \"ISIS.\" Some send money to front business set up by the ISIS organization such as the Al-Aqsa Foundation which is found on many terrorist watch lists now. Other times a person pays for a regular service or good - like food at a grocery store - and the store owner ten cuts a check to an ISIS member who can deposit into an account used for purchasing guns and housing for soldiers. You can see how the rabbit hole can become very deep. \n\nThe hardest part in all this from a Compliance industry perspective (or obviously my own take on the industry I am professionally involved in) is that things operate on hindsight and predictive analytics. It's easy to flag a terrorist after they kill someone and are captured from a battle ground, less easy to identify people who haven't done anything illegal. After all, like I said, some ISIS supporters don't go to war and just provide a home to live in or a personal check. Not illegal until you can connect the person receiving the funds with ISIS and depending on location the intention of the individual providing the service or money. \n\nThe last stop in this overview is at the level of governments - and how they are motivated by money and self-preservation in most instances, above all. When financing of terrorism comes from the state level - true power is really provided to ISIS. An example outside of the world of terrorism is the development of the country of Israel not too long ago. It required a push from countries around the world for land to be granted to the Jewish people so they would have a permanent state. In the same way, the goal of the Islamic caliphate is to create a state (or world) for Muslims. Microcosms of this exist in countries like Saudi Arabia and Iran that having Islamic banks and Sharia law systems.\n\n ISIS is terrifying because they are emulating past state creations but now with a camera constantly affixed on them - but often controlled as well. ISIS has some top tier marketers and video/photo editors out there and this has allowed them to breed fear and submission on a global stage. Yes, politicians may speak out against them and people hold candlelight vigils outside of terror sites, but these things do not control ISIS. They manipulate every word to new propagandas - some of which you can readily keep up with in your language of choice through the ISIS magazine DABIQ. \n\nMy end thoughts - you have to kill the money trail. It's not as simple as we would like it to be and is made worst by corruption at the state level where terrorism can easily be funded. Engaging in actual war is probably mostly useless, especially if war is fought by just killing a handful here and there in isolated situations. It's largely symbolic as it makes people feel like actions are being taken to remove the threat, but for some embedded in the theology of ISIS every death brings one closer to god. As a result, many with ISIS seem to lack a fear of death, a factor that makes them a different enemy than just \"going to war with the German Nazis.\" ISIS is truly terrifying for me as they can be an invisible enemy when they want to be, and few will stand in their way. \n", "ISIS is a manifestation of ideology of an oppressed people. Many religions like Christianity and Judaism trace their roots to oppression and non-conformity to prevailing power structures, beliefs and elites. ISIS can and will be defeated but with the seemingly intractable conflict in the Middle East it seems the ideology itself will continue to evolve and spawn new manifestations. The question could rephrased to 'Why is an ideology difficult to defeat'? Ideas can never be defeated but radicalisation can be. When pursuit of any ideology becomes rabid societies tend to self-correct. There will always be opportunists who see gold and power in fomenting and correcting adjustments. Sometimes opportunists and extremists trip over each other.\n", "ISIS is never going to end. Terrorism in general is never going to end. It's a religious cause, that spreads the message of slaughtering the non-believing masses, in the name of Allah. People actively come join the cause, not the army itself. So even if we came to defeat their leaders, take back the territory they stole, the message is gonna expand across the entire world.

air mile/frequent flyer credit cards
Hi, I just turned 20 and am looking into applying for a credit card. I have saved all the money that hasn't gone directly to rent, living expenses, or tuition since I was 16, and fully intend to pay off the balance in full every month. That being said, I have no idea what in the world an Air Mile/Frequent flyer credit card is and how they work. I know my parents have one that they put their large purchases on, and I have the option of getting one, but is it worth getting that over a rewards card? Also, is it limited to what carrier fulfills it? Are those cards the reason people board hours before me at the air port?

The only difference is that the issuer will offer an incentive for you to use the card, in the form of \"rewards.\"\n\nBasically, the way credit card companies can afford to \"reward\" you with anything such as mileage or redeemable points is that every time a credit card is swiped, the issuer gets a small percentage of the overall purchase, charged as a fee to the merchant swiping the card. The issuer then gives you an even smaller percentage back as a \"reward\" for using their card.\n\nNow that this has been established, the way the credit card issuer chooses to reward you is variable. People who travel often may opt in for a card that rewards them with airline mileage, whereas other people who like cash back may choose a card that rewards them a percentage back on groceries or gas.\n\n > Also, is it limited to what carrier fulfills it?\n\nUsually, yes. Check with the company issuing the credit card for more details on how you can redeem your rewards. There is no \"standard\" for how these things work, it is up to each individual issuer to setup their rewards program however they'd like.", "Air mile cards are just one kind of rewards cards. If you pay off the balance every month, you might as well use a rewards card as the fee for using a credit card has basically already been built into the price of what you are buying.\n\nMost airlines offer a credit card that is linked with their own frequent fliers program. If you spend enough on the card and/or fly enough this can give you additional perks like boarding early. It varies a lot from airline to airline though so do your research.\n\nCC issuers deliberately make their rewards structure opaque and hard to understand (e.g., rewards change after 3 months or the value of a \"point\"). I would try and find a trusted 3rd party site that reviews credit cards. I found this one online: _URL_0_", "At 20, unless you really want/need those miles I'd forgo the airline cards in favor of a standard rewards card. While CC issuers *do* make the rewards tier a tricky game to follow, the right cards have locked rewards that can be useful. My AmEx gets me 3% points on groceries, so it generally only comes out at the market. My Amazon Visa is 3% on Amazon purchases, so that's where it gets used. Shop at Target? Their card is 5%, applied at the register. I use the different cards exclusively (no debit, no cash if I can) and by paying off the balance *every month* I make back around $500 a year between them. Which is a month of free rent. :) As none of the cards have an annual fee, this costs me nothing.\n\nTwo handy websites that will evaluate your needs and make recommendations for CCs that are appropriate to your situation are [Credit Sesame](_URL_1_) and [Credit Karma](_URL_0_). Both require your social security number to access your financial information, but they're legit.\n\nMost importantly, ask yourself why you want the CC. Are you interested in building credit? Just want it in your pocket in case of an emergency? CC issuers rely on people being careless with their cards, and the effects a CC *will* have on your credit are far-reaching. Do your research and find the right, no-fee CC for your needs. Establishing good credit at your age is easy and so, so important. You don't want to be walking back mistakes made today years from now, and barring some uncomfortable alternatives -- bankruptcy, going into financial hiding for seven years -- these decisions will be with you that long." ] }

My secondary school got a little (around 12m high) wind turbine to make themselves look green, and that thing won't pay itself off in energy produced for decades, whereas the solar panels that they put on the roof of every building paid themselves off within a few years. Now the school is completely carbon neutral (meaning it produces all of the energy it needs) in summer. \n\nWith solar power you get near-constant sunlight. Sure there are peak hours, but the sun is always overhead during the day, and gone at night. In contrast, wind power is nowhere near as reliable: there can be no wind, too little wind, even too much wind. I was in Devon and Cornwall during the January/February storm in 2014, and I saw a lot of shattered wind turbines that were either completely broken or had been disabled, pending repairs.\n\nSo in summary, the basic technology behind wind power is nowhere near as advances as solar power, on top of that wind power is reliant on a very unreliable resource. Offshore windfarms are superior to land-based windfarms in about every regard, which is why there was a big movement a few years ago to install a lot of them in the North Sea off the coast of Scotland (which pissed off Donald Trump).\n\nThe one advantage wind has over solar is space: solar farms require vast amounts of space to be covered, and there really isn't much of that in the UK. With wind turbines, a large amount of them can be installed in a relatively small area for their size.\n\nIf you are looking to make a property more energy efficient, invest in solar power, not wind. If I recall correctly the government will actually pay you for providing to the national grid if you produce a surplus amount of energy (although the government might have axed that)." ] }

why build streetcars/trolleys when busses work fine?
I have a hard time understanding what benefits do streetcars have over busses as a form of public transportation in cities. Streetcars need to stop at traffic light, just like busses and they move at similar speeds. If you need a form of public transit that isn't inhibited by traffic lights, light rail and subways should work (albeit a bit expensive.) But I don't understand the value added by spending lots of money building rail tracks on roads and running streetcars on them.

Also, if you do make a mistake, you can easily fix it by getting off and back on going the opposite way. Streetcars just feel safer and easier to tackle for someone who isn't familiar with a city, which is why I was thrilled when my city started putting in new streetcar lines in some of the most popular tourist areas.", "In addition to what Teekno says, developers like streetcars and subways better than bus routes.\n\nDevelopers take public transportation into account before investing in building a new project. A bus line can be moved on a whim, so they are less sure it'll be there. A subway or streetcar line will not be moved easily, so the developer can count on it and be more confident in his project.", "Around a century ago the question was the reverse, we have busses because of tire and gas businesses." ] }

There are three different interpretations:\n\n1. **X has a lawyer on retainer**. This means X pays a monthly fee to an attorney to handle whatever matters come up. The lawyer may work exclusively for X/X's company or may have other clients as well. The key is that this lawyer is being compensated to carve out a piece of his time to devote exclusively to X. This is obviously incredibly expensive so unless the person you're talking to is rich af this is not the case.\n\n2. **X has worked with an attorney in the past***. The average person needs legal services fairly infrequently. When they need something they go to a lawyer and pay a one-time fee for a one-time service. I'm talking wills, property deeds, lawsuits, one-off consultation, whatever. So when X says \"my lawyer\" they really mean that they will call this attorney and arrange for him to handle the matter in question. How dishonest their claim of \"having a lawyer\" is is kind of up for interpretation. If X has regular dealings with said lawyer it kind of holds water. If X is talking about the guy who wrote their mom's will 20 years ago then they're just bullshitting. Which leads me to point three...\n\n3. **X is bullshitting**. Incredibly likely. X is just trying to scare the person they're talking to into giving them what they want.", "wait do people actually say this?", "People who have a lawyer have no need to advertise it. Their lawyer would get into contact with you. The person more than likely would let you figure that out." ] }

", "No one (at least in the top few posts) is discussing the fact that basements are usually not accounted into the limitations the municipalities post on house-owners in terms of built up area or maximum number of floors. For example, to give a *village* example since those are simpler, in my dad's home village the maximum allowed of \"above ground floors\" is 3 excluding the ground floor. The maximum percentage of land space one is allowed to build the building on is 40% of the total land space (so if the land is 100 squared meters or around 1000 squared feet, above ground floors can only have an area of 40 squared meter or 400 squared feet at most each). There are also restrictions regarding how much of each floor is allowed to be in balcony form and so forth.\n\nThese restrictions don't apply to basements in most cases I've seen. In the same village that I discussed above, you can keep going down with extra floors without any restrictions as long as you don't hit any water table or make the neighboring land unstable); I've seen as much as 5 basement floors on a 8-floor building (including those 5 floors). You can also utilize 100% of the land area to build on (i.e. you can use that whole 100 squared meters or around 1000 squared feet).\n\nNow the other aspects have been discussed: you usually need level the ground either way to build on (I almost never seen a land with leveled ground). Plus, in many instances you need to go a few meters or feet into the ground before you can lay the foundation because the top layer of soil is organic which is useless for construction (and damaging if anything). If you're going to have to dig a bit and work on leveling, then you might just at once go that extra mile and dig enough for a basement since you already mobilized all the digging equipment. In the case of a high rock-bed, however, digging is too costy that you're better off leveling your ground by adding material over the rockbed and then building upwards.\n\nThat's the general notion from an engineering perspective. One may also discuss how basements are safe in extreme storm situations and such.\n\nEDIT: I read a few more second and below level comments and noticed /u/NoUrImmature mentioned the points I discussed." ] }

why can't we mass produce super microbes to decompose plastic at faster rates?
After watching a documentary (Plastic Paradise) on plastic and its damaging effects on the environment, I googled around and ended up finding a few articles on people (one of them being a teenager named Daniel Burd if that matters) isolating microbes that sped up the degradation process of plastic drastically. However, it seems like those findings went no where and plastic is still flooding our oceans/landfills at a growing rate. So my question is: what's preventing us from using the solutions gained from previous experiments to combat this crisis?

The US was in a position to be the largest manufacturing country in the free world, and had tremendous market share when it came to rebuilding Europe and Japan. Once Europe and Japan were rebuilt, all that demand went away.", "The issue with the US economic system is that it did not cope well with globalization for the secondary (=industrial) sector. Your economy was (is) built on a strong domestic market demand, which was and still is the driving factor behind large parts of the economy in the US. That's what made the US the biggest economy worldwide. \n\nBut it also lead to the fact that quality and invention fell behind. No need to be competitive when you just won the cold war and globalization was not yet beginning (good example: GM was the biggest manufacturing conglomerate worldwide, yet they sold 90% of their stuff domestically because it was uncompetitive in the global context) \n\nNow think further: due to the US dollar being a relatively strong currency the average American still has a decent amount of money to spend compared to a Chinese factory worker - but due to globalized markets folks now have the choice which things to buy. So average Joe began spending his money on foreign products, which are for the most part better value for money. The cheap side of products have been covered well by the Chinese, the craftsmanship has been covered by the European and the Japanese. \n\nSince average Joe now can get 2 Chinese washing mashines instead of one crappy GM washer or one reliable Toyota for the same price as a crappy Buick, he'll now spend his money abroad. \nThe problem is that Joe might work for GM. So he'll get a pay cut after couple of years because his company doesn't sell enough stuff. The chain reaction has started. \n\nSo over the years the US have built up a huge amount of yearly import surplus (this means that year after year you buy more than you sell, actually living on credit) which keeps on rising. \nIf you see \"the US\" as a corporation that means negative cash flow for the last 3 decades and huge dollar reserves are now held by Chinese and other countries. \n\nNow there's two ways to fix it: you can limit imports and force your own people to buy the uncompetitive products again (see Trump)... Or you can incentivise American companies to excel in their fields, making it even possible to not only sell their stuff to locals but to actually sell it worldwide.\n\nThe second mentioned way actually works amazingly fine for the US in software and fintech areas of the economy (see Google, Microsoft, and generally the tertiary sector). But even though the tertiary sector takes the biggest part of the cake, it's still not enough to offset the erosion of the secondary sector at the moment." ] }

how people can get so connected to an actor (or other pop culture figure that they have not met and do not truly know) that they cry or feel deep despair upon death.
I am not trying to be disrespectful, I just truly do not understand it. Of course the loss of life, especially the case of suicide, is a sad occasion. But with Robin Williams, Paul Walker, Michael Jackson, etc. I see people write online how a particular death has just crushed their life and how they have been so emotional and crying over it. How do we allow people that we have never met, probably will never meet, and who we do not know outside of characters affect our emotions to such a degree?

Let's use Robin Williams as an example. How many fond memories do you have of his work? How many times in your life did he make you laugh? Every time he did he made you happy and that's a deep emotion. He is someone who literally made you happy and may have done it throughout your entire life.\n \nNow compare that to the girl who sat two seats away from you in a math class - you might know her name and have talked to her a few times but she never made you laugh, and maybe the only emotion she ever gave you was annoyance when she asked to borrow a pencil. \n \nOne of those people is someone you never met but they brought joy into your life, and the other is a person you knew but was little more than a generic human being to you. Which one's death will move you more? It's an easy choice (unless you want to be argumentative). We care about people who make us laugh, or people who create literary characters we love, or who write and perform music that makes us want to dance -- and that is perfectly normal. When those people die we feel the loss in our own lives and that is perfectly normal, too. It isn't something we \"allow\", it is plain old human nature. ", "I feel Robin Williams carried his personality with him in every character he played. I grew up watching his films. They would cheer me up when I was feeling down. In a way watching films with actors that manage to touch our hearts allows them to become a part of our lives, almost family. Robin's voice is more comforting and familiar to me then most my family. ", "Hey looks like I can finally put that philosophy degree of mine to some good use!\n\nI took a course called the philosophy of emotion my senior year. In that course, emotions were understood as a type of evaluative judgment of objects in relation to our conception of a well lived life. For example, the presence of a friend makes us happy because we view the friendship as a valuable part of us living the life that we want to live. \n\nGrief is a little more complicated, but follows the same principles. In grieving, we are acknowledging a loss of a person (or pet, thing, etc.) that had significant value in how we view ourselves and our conception of a well lived life. This ties to Robin Williams, (and other celebs), because many people experience them through their work, getting to know an aspect of who they are which fits really well with their view of what should be valued in life. Though I'll never know Robin Williams as well as I know my family, through his work I can come to some understanding of what he valued: laughter, friendship, etc. What Robin Williams represents is so integral to some peoples lives that they see the loss of the actor as the loss to a source of things that they find valuable within their own lives.\n\nOne of the books we read also stated that there are ways that we can make evaluative judgments that are off the mark, too. This can lead to emotional reactions that don't quite seem to fit the situation. If you've ever gotten *really* angry over something small, like lost keys, it can be an indicator that you've judged the keys as far more important to your conception of a well lived life than they actually are (because, to some level, you know you'll find them eventually). Some people are likely doing this with celebrity deaths as well. Whether they are doing it because the given celeb truly did have a huge impact on them, or they are merely blowing things out of proportion subconsciously depends on the person, but the effect is the same either way.\n\ntl;dr We get sad because well lost someone who represented something that we value as good in our own lives.", "As an actor, we learn that the best actors are the ones who take down their defenses and expose their vulnerabilities to the world. That creates an intense connection between performer and audience member. It makes the viewer find something in the character that they see in themselves, whether it be funny, sad, scary etc etc. And because of it, you feel like you know the person. All of these characters that Robin Williams played are obviously not entirely who he is. But in order to connect to that vulnerability, he needed to bring out aspects of his real being. \n\nI have spent my life watching Williams and really connecting to all the stories he wanted to tell, from the intensely dramatic to the ridiculously funny. Having seen just how easily he could reach the heartstrings and affect a human being on a deep an emotional level, you can't help but shed a tear for him. What he has done is no easy feat, and for that he deserves his label as a legend. ", "I've never cared really because people die every day. That being said, when I read a couple accounts of people who did know Robin, I felt very sad. Not for my loss, but theirs.\n\nI've never felt any sadness for a celebrity death before this, and this is probably because he seems to have touched so many in his life." ] }

Phone manufacturers try to squeeze every last bit of capacity out of the battery so charge it to the maximum safe voltage.\n\nSince laptops are often left plugged in all the time, to help slow down degradation of the cells they are typically charged to a slightly lower voltage. But leaving them plugged in all the time will still degrade the cells faster than storing the laptop at say 60%.\n\nSqueezing that 5-10% extra charge into a battery can cut its life 10 fold.

This is often done for electric cars, where they are advertised with a higher capacity than what is actually available.", "I understand it like this. In a smart phone space is limited. The phone always operates from the battery. When charging, the phone can't use the incoming electricity directly. So you have the heat of the phone use plus the heat of charging. Your car can operate directly off the alternator so it's different. I believe the laptop can also use the electricity from the power adaptor so you do not get this doubling of heat either.", "Others have already mentioned the heat issue, but I want to highlight a problem with wireless charging. See, with wireless charging, your battery is being charged *and* used to power your phone, so that puts far more stress than either charging or being discharged (used to power your phone) separately. When you charge your phone using a wire, it provides enough power to not only charge the phone battery, but also to power the rest of the phone so your battery isn't being discharged. " ] }

The presence of a US base is considered a deterrent to any would-be aggressor. In the event of crisis, the US already has assets in place, and can reinforce those assets easier. It also helps US and the host country integrate their warplans and to train together. In other cases, the US leases bases in strategic locations around the world to get airfields or ports.\n\nIn Japan's case, after WW2 ended, the US occupation transitioned to a mutual defense arrangement against Soviet and/or Chinese moves in the Pacific. US bases in Japan were used in the Korean War. Japan has never actually signed a peace treaty with the USSR or Russia, and they still dispute the Soviet/Russian occupation of several islands.\n\nThere are no Japanese or other foreign bases in the US, but there are foreign contingents on a number of US bases. Not for mutual defense, but for training. Foreign troops rotate through US training schools pretty regularly.", "Surprised that no one mention that after ww2 Japan wasnt allowed to have military, and protection of Japan was put on US shoulders. Even now there isnt actual army in Japan, but something similar to National Guard. And only few months ago they were approved to participate in operations outside of Japan. ", "Mostly because of WWII. The US won that war and the losers like Italy, Japan and Germany weren't really in any position to say no to these bases.\n\nThere are no real foreign military bases in the US like the ones the US has in the former Axis countries, but there are some smaller institutions.\n\nfro example Holloman Air Force Base houses a German Air Force Tactical Training Center with a few hundreds German service personal and a number of German jet-fighters.\n\nThese 'bases' however have a vastly different status than the US bases elsewhere.", "for japan, it's part of a treaty that had to do with them losing during WW2.\n\nin europe, the US was the only one in a position to oppose russia, since most of them had to rebuild so much infrastructure. you can still see a general outline of where the USSR border was from where US military bases are.

why do video game graphics, animation, world size, and gameplay options advance in leaps and bounds, while ai seems to have barely advanced at all?

It wouldn't be harder to beat per se, it'd just make some different decisions, but you'd have to play hours with it just to notice the pattern. \n\nAI does advance, it's just hard to tell.

One of the problems is that AI programming is harder to reuse. If someone makes a 3D rendering engine, they can use it for any 3D game, from a princess themed puzzle game for kids to a violent sci-fi first person shooter. However, the brilliant AI you craft for one of those games won't help the other. You'll need very different AI for a first person shooter compared to what you'd need for a strategy game or a racing game.\n\nEven within a specific genre, AI has to account for unique aspects of the game. A \"realistic\" racing game would require very different AI than a racing game that has jumps and power ups. A small scale action game requires different AI than an action game with squads or large armies. You might be able to reuse some aspects of AI across multiple games, if they are similar, but for the most part AI can't be reused as much as other assets." ] }

how much electrical power do airplanes have to power all the main pilot systems and passer entertaintment systems?
Every time I'm on a plane, I wonder how much energy the plane needs to power the whole thing with 100~300 ish passengers all using those in flight passenger entertainment systems. Do planes have like a hybrid system to gather energy from engines? How often do they get recharged? How big is the capacity of the battery(s)?

why does ibm watson still sound robotic when it speaks even though it can process natural language?
I just find it very odd that IBM watson still has the typical text to speech type voice that doesn't really fluctuate except for the obvious parts such as questions and pausing for commas/periods. Shouldn't it be able to sound more natural given the amount of computing power it has or was this an intentional choice by the team behind it?

When you think about touching from the perspective of the sense of touch, what you are sensing is pressure, or force. Do atoms exert forces on each other? Certainly yes, via electrostatic repulsion and the pauli exclusion principle. Do atoms have hard surfaces that can directly come into contact with each other? No, at an atomic scale, is doesn't make sense to think about subatomic particles at hard objects with some defined surface that can touch another hard object with a defined surface.", "Most of the time when we're talking about \"splitting the atom,\" we're actually talking about atoms more-or-less spontaneously going through the process of [radioactive decay](_URL_0_). Some atoms are inherently unstable and will eventually fall apart on their own. Exactly how long that takes depends on the element we're talking about. A carbon-10 atom has a 50% chance of decaying within about 20 seconds. A hydrogen-3 atom (sometimes called \"tritium\") has a 50% chance of decaying in a bit more than 12 *years*. But the point is that atoms splitting in this manner doesn't involve \"touching\" atoms. They'll fall apart all on their own.\n\nThat said, when atoms do decay, they can throw off sub-atomic particles in addition to two smaller, complete atoms. These particles can collide with other atoms, though most of the time they don't. If it does, the affected atom will most likely immediately split. As the number of unstable atoms in a small area goes up, the odds that one of these particles will hit another unstable atom goes op. Get enough of these atoms close enough together and it can reach \"critical mass,\" leading to a chain reaction of atomic decay and particle collisions such that a significant percentage of the mass will very rapidly decay almost all at once, releasing a potentially *enormous* amount of radiation. Controlled critical masses are what drive nuclear power plants. *Un*controlled critical masses are what drive nuclear weapons. \n\nSometimes though, we really are talking about what amounts to physically hammering an atom apart. This happens in particle accelerators, where a stream of particles (atomic or sub-atomic) is magnetically accelerated to a significant fraction of the speed of light before being directed to slam into a target. Most of these particles will miss, but a few will connect, sometimes leading to atoms splitting apart. " ] }

in tv/movies we always see stand-offs between guys with guns. in reality shouldn't you just shoot as soon as possible?
**Scenario:** two men, each with guns, are standing roughly five feet from each other. Each gun is aimed at the other person's head. From this distance we are assuming neither person would miss. They sit and talk until they agree to not shoot, or they both winding up shooting at the same time. **Reality:** Shouldn't you just immediately pull the trigger? Because we are assuming you won't miss, at this distance a head-shot should kill the person before they know you pulled the trigger. Are we just worried that in death their muscles will contract, causing them to pull the trigger? Is this a reasonable thing to fear? Or, is it a simply psychological thing, not wanting to pull the trigger? **EDIT:** Can anyone answer the science side? If two people are standing close to each other, guns aimed at heads, and one person shoots first, what are the odds of 1) the second person being able to fire as well, intentionally or from involuntary death spasms, and 2) actually hitting the first person in the head (remember, that's where the gun was originally being aimed).

All words borrowed from English get the article 'de' (masculine) unless there are other rules/exceptions. One exception is, for example, is if the word is a form of a verb, it gets 'het'. So it would be 'de race' (The race) but 'het racen' (the act of racing). People don't really think about the rules though. It is so natural for us to put 'de' in front of an English word that we don't even think about what rules to use.

In France, they have the [Académie Française](_URL_0_) which decides what new words will be when translated. \n\nThis is because France is very conservative about their language, and want to prevent \"Franglais\" becoming a big thing (when French speakers use English phrases such as OK)", "With most languages, it is a fairly organic process. People decide on its usage simply by using it, and once it appears in print it is considered notable enough to be introduced to a national dictionary, similar to the Oxford English Dictionary or Merriam-Webster for British and American English.\n\nFrench is a notable exception, though. [L'Académie française](_URL_0_) is a council which dictates the usage (including gender) of new words entering the French language. For example, when the iPhone was released they decided whether the word 'iPhone' was masculine or feminine. They wield such power that the release of the iPhone was delayed in France while they deliberated, even though \"the iPhone\" would be \"l'iPhone\" in French, whether it's masculine or feminine. They went with masculine, in case you're wondering.\n\nGoogle and Auto-Tune are both trademarks (Auto-Tune is owned by a pro-audio company called [Antares](_URL_1_)), and so l'Académie doesn't get to say how they're used. Even though both terms are close to becoming generic, trademarked terms are not in l'Académie's remit.\n\nBut to take a word like 'download', l'Académie français are very against \"franglais,\" the taking of an English word, saying it in a French accent and calling it a French word. They were too slow-acting to come up with a word for \"internet,\" before the Franglais (\"l'Internet\") became widely used, so they jumped on \"download.\" \n\nThe French word for 'load' as a verb is 'charger', e.g \"I'm loading a box with cats\" would be \"Je charge une boîte des chats.\" So 'charger' is fine, you're loading your computer with stuff.\n\nBut do we really mean 'down' in English? The internet isn't higher up than your computer. It doesn't come down a hierarchy to get to you, all computers are equal on the internet. And the French don't like hierarchy all that much anyway, see also The French Revolution. But you can be sure that the 'load' is being carried over some distance, the same as telegraphs, telephone calls and television broadcasts. And so they went with \"télécharger\" for the verb \"to download\", and following the rules of French grammar, \"Téléchargements\" for your \"Downloads\" folder, i.e. stuff you have downloaded.

Sum-soong, whar-kraft, hull-o (halo).\n\nThe genus is usually determined organically. You can tell from the sounding of the word whether it is masculine or femenine or neuter. \n\niphone, android, google for instance are \"he\"\n\nmotorola is \"she\" (notice letter -a at the end)", "Others have already chimed in that it's going to depend on the language. I can help for ASL (American Sign Language).\n\nTypically, one of 3 things happens:\n\n1. A \"glossed\" sign is given to the word. It's not exactly conceptually accurate, but it's what a similar English would would have as a sign. Example is \"server\" (as in internet, not restaurant) signed as SERVE (as in serving at a restaurant).\n\n2. The word is spelled or given a loan-sign (condensed spelling). Examples include \"software\" spelled out or left at S-W (if in a technical field). The same is true with \"database\" (spelled or D-B).\n\n3. A sign is created. This is where it gets neat, because ASL sort of has a physical center at Gallaudet University in Washington, DC. More often than not, new signs come from that campus as a result of over 1500 Deaf people interacting on a daily basis. Examples include \"Barack Obama\" signed as B--- > O with the palm inward and the hand pulled from the center of the body outwards. With the explosion of the internet/mobile technology/inexpensive video recording, forums like Facebook and Youtube also act as avenues for sharing regional signs or discussing new signs. Unlike many languages where usage \"just happens,\" this process actually includes discussion and debate. Examples of this process that I've seen include the sign for Glide, a video messaging app, as well as culturally/internationally-based signs like country names or religious vocabulary.", "German here.

Why and how new words are assigned a gender is quite interesting, not fully understood and probably dependent on the sound of the word or what it means. iPhone is neuter (\"das iPhone\"), probably because telephone is neuter too (\"das Telefon\"). E-mail is female (\"die E-mail\", maybe because it stands for \"die Nachricht\", but it's \"das E-Mail\" in Austria for some reason), download is male (\"der Download\", maybe because it describes a process, \"der Vorgang\"). But once a gender has been generally accepted everything else sounds pretty wrong. For example, modem is a normal german word by now and is neuter, \"das Modem\". However, it is a combination of modulator/demodulator and \"der Modulator\" is definitely male. So in technical texts the modem is referred to as \"der Modem\", which is technically correct, and in common speech it is \"das Modem\" and if someone uses \"der Modem\" colloquially you can safely assume that that person is a weird and/or pedantic nerd. \n\nGooge doesn't have a gender, we just say \"Google\". You wouldn't say \"the google\" in english too. When used as a verb it becomes quite cumbersome however. Because google is pronounced \"googel\" verb inflections are unusally germanized like this, so \"I googled this\" becomes \"Ich habe das gegoogelt\" instead of \"gegoogled\". \"I downloaded this\" would become \"Ich habe es gedownloadet\" or \"downgeloadet\", which is both utterly terrible and only used as a joke, we use a german word then, [\"herunterladen\"](_URL_0_), which is just a literal translation. ", "Swedish has two articles and a number (7-ish) of different ways to form plural. Any native speaker has a feeling for it and can tell what's \"correct\", especially re. the articles. Rules for new words are formed informally and organically.

I do use the feminine form.", "Unofficially, in Latvian, everyone just uses the original version pronounced in local accent/style plus any local grammar rules. Mostly these are borrowed English words. Doubly true with brand names. Usually that means mispronouncing it plus adding Latvian suffix. Basically, the base is preserved and usually pronounced as if local rules apply, which is that letters are almost always pronounced as written in Latvian. Most words get altered liberally to fit sentences as if they had local language rules. I notice most words become masculine, probably because most English words either end with consonants or silent vowels and feminine words in Latvian predominantly end in pronounced vowels.\n\nOfficially, the council/ministry (don't know their official name) generally suggests/creates new \"pure\" Latvian words for common borrowed words and then nobody uses them because they are just confusing and often stupid-sounding. Latvian language \"experts\" are notorious for trying to make their own versions.

Take \"Internet\", for instance. The word for \"net\" in Spanish is \"red\", which is feminine, therefore some people say \"la internet\". But the words ending in \"-net\" we've borrowed from French (i.e. carnet, bidet, spelled in Spanish without the silent \"t\" - carné, bidé) are masculine, so \"el internet\" is also used. From etymology, \"email\" is \"correo electrónico\" (masc.), so \"el/un email\". Most English words tend to be masculine for some reason, like \"el selfie\" even though it's a photo and photos are feminine... anyway... New verbs are all regular and go in the first conjugation (\"-ar\"), so \"goglear\", \"tuitear\", \"faxear\". ", "Very interesting topic OP.

Of the former, they are generally people who try to look at a language as it is actually used by everyday people in everyday life. (I am not referring to specialist terms). Prescriptivists, I divide into two general classes: first, those who genuinely look at the research of descriptivists and attempt to define rules in grammar and spelling (at least for the historical moment), and second, the hide-bound (look it up) pricks who essentially say \"my way or the highway\" and refuse to accept that language is a living, changing thing.

My own field is sociolinguistics; my life-long hobby is etymology.", "I'm a native English speaker studying Arabic and living in an Arabic speaking country, but who is far from fluent. So take what I say with a grain of salt.\n\nIn the local dialects of Arabic (the everyday language which people speak), it seems to be an organic process; there is no council which decides. But what I find fascinating, is how foreign words are then used in the language. The foreign word is taken and then plugged into the root system of Arabic.\n\nFor example, here in Tunisia there are lots of loan words from French, such as \"قلاس / glaas\" for ice cream, from the French \"crème glacée.\" The G L S from the word is then taken and put into the verbal root system so that you get يقلّس / ee-gal-lis for he freezes (_URL_0_.) or نقلّس / n-gal-lis for I freeze (_URL_0_.). Or in the completed form, قلّسَت / gal-la-sat for she froze (_URL_0_.). I'm sure there are better examples, but it was the first one that popped into my head.\n\nAlso, they will use the Arabic system for making plurals. FYI, as a foreigner learning Arabic, plurals are the bane of my existence as there isn't just one way to do it, but many; more so in written Arabic.\n\nSo here in Tunisia, there seems to be two main ways of pluralizing a foreign loan word. One is by adding a long aa sound in the middle, such as :\n\nCenter: سنتر / cen-ter -- > سناتر / ce-naa-ter\nDriver (chauffeur): شفور / shufuur -- > شوافر / shu-waa-fur\n\nAnother way is by adding a \"aat\" at the end of the word, which corresponds to the way Arabic pluralizes a feminine word.\n\nPermit (permis): برمي / per-mii -- > برميات / per-miy-yaat\n\nAnyway, there are ton of other examples. Arabic is a fascinating language, especially how all the words derive from a very logical root system. It's interesting too then to see how foreign loan words are integrated into that root system.", "Lithuanian. Language comitee are nazis here, so the word will have to be used for quite a while to be accepted by them. Generaly people tend to use it by familiarizing with what already are used, or by synonimising stuff, like iPhone - is a phone, thus as a phone is masculne, so is an iPhone. With google it's different though. I've probably heard every kind of a conscruction used in lithuanian there could be... if commitee weren't snail conservators, could be easier to just adjust the word usage by some existing language rule.", "First of all, the word might be modified in the language: it might be translated (as a calque), turned into a completely different word, or, in the case of languages that use a different script, transliterated (converted into the script used by that language). Typically, brand names are left unchanged.\n\nAs for genders, various languages do one of the following:\n\n* Use the gender of the object as the gender of the brand name. For example, \"Google\" is a search engine, and in French, that is *un moteur de recherche*, which is masculine, and so \"Google\" is masculine in French. Similarly, the brand names of cars are feminine in French, as the word for car (*voiture*) is feminine: *une Peugeot*, *une Rolls-Royce*\n* Use the default gender, which might be neuter, or, if there is no neuter gender, masculine\n\nEDIT: grammar", "I can speak about some newer words in Chinese. For things that are general use/ defining words, there is usually organic adoption for a Chinese phrase that kind of represents the meaning of the word, for example, computer is translated literally as electric mind/head (電腦) and password is translated as secret (密碼). More specific cases like companies and brands that become ubiquitous with the services they offer often get pronounced according to their latin spelling/ an approximation of their English pronunciation.", "Sometimes a language may reanalyze parts of words to determine these things. For instance, when Swahili borrowed the Arabic word *kitab* (as *kitabu*), the [ki] portion as the Class 7 marker (Swahili classes are like grammatical gender, each noun gets one class in singular and another in plural, and this triggers agreement) -- and suddenly in plural it is class 8 *vitabu*!

why does choosing the frequency band of wifi (2.4 ghz and 5 ghz) affect the speed of wifi, but for mobile frequencies (e.g. 3g and 4g), it doesn't matter?
From the articles I've read (and from personal experience), I understand that a 2.4GHz Wi-Fi signal provides internet to a larger area but sacrifices speed, while the 5GHz band provides faster speeds to a smaller area. However, when I look at the frequency bands used in 3G mobile (_URL_0_) and 4G mobile (_URL_1_), the frequencies don't seem all that different? There are frequencies used in 3G which are higher than 4G but yet 4G is so much faster than 3G. Why is this different from WiFi?

Meanwhile there are a whole bunch of LTE frequency bands that support 20 MHz channels giving a peak download speed 4x higher if they were using the encoding.\n\n4G also improved the encoding to make better usage of the bandwidth which resulted in even higher speeds." ] }

latour's actor network theory
Hi ELI5! I'm wondering if any of you could explain Bruno Latour's Actor Network theory to me in simple terms. Thanks in advance!

{ "a_id": [ "cah5j64" ], "score": [ 6 ], "text": [ "Actor-Network Theory, or ANT for short, treats objects as if they were active participants in a social network. One way of thinking about this would be your apartment. Yes you live with your two roommates and might think there were three people in your social network, or more if you include your loud neighbors. But you'd be leaving out the smoke alarm which is an active participant to your network in that it wakes the whole apartment up at 6 in the morning when Roommate #2 is making toast before work at the ER. The smoke alarm is part of your social network and its actions, or failure to work, drastically affect your social network. ANT claims the smoke detector is \"performing\", and though the range of actions available to it are limited, it's still fundamentally not too different from how other roommates act and affect the network. furthermore, when your smoke alarm fails to perform, you might not be conscious of it until that lack of performance affects the entire structure of the social network, like as in the moment when you stop thinking about your apartment as a place where you live so much as a lot of rooms full of fire. \n\nThis probably seems self-evident, but now try to imagine the microscope in a lab and how its performance or lack of performance can affect the outcomes of scientific research. Luckily I think that Latour overextends himself here and we can trust the validity of the scientific process because it repeats its experiments again and again in slightly different conditions until we get a pretty good idea what the \"crucial\" things are. Nevertheless, it's a useful reminder that simple objects can have a profound ability to speak to us in really subtle ways to the point where we might not want to draw a strong distinction between a person and a smoke alarm." ] }

A benign tumor's cells are content to stay where they are, and aren't threatening other parts of the body.

Now it can both divide in the wrong orientation, and it can deactivate the immune response to itself. Oh, but it runs out of blood supply quickly as the tumor grows. \n\nNext, it develops a mutation that lets it release molecules that signal new vascularizaiton (e.g. veins). Now it has a fresh blood supply and plenty of nutrients to continue growing.

Some cells have to go through ~8 major mutations, others only have to go through ~2.

The slight angle you mention is more that the muscles that support walking, are weaker in some places. If you, or anyone else, force their feet a bit more parallel, you will feel sore in places you didn't think existed and it will probably effect the muscles all the way up to your back. \n\nThis weakness in certain muscles pull on your knees and hips, which can eventually lead to knee and hip pain and even surgery. \n\nI don't however, have an answer for animals. It could be a similar issue, but I found that when most really start running they straighten out. \n\nAnyway, that's the best summery I got from when I looked up the answer. " ] }

if the body's immune system is geared to cleanse foreign bodies that invade, how do tattoos stay in the skin and not get flushed out?

You might find this interested _URL_0_", "I believe the ELI5 version is that the ink particles from the tattoo are larger than what can be broken down by the body's defense mechanisms. \n\nSo, basically when tattoos are \"laser removed\" the laser just breaks the ink into smaller particles and the body goes through it's natural defense cycle to remove the ink. ", "When you look at a person's tattoo, you're seeing the ink through the epidermis, or the outer layer of skin. The ink is actually in the dermis, which is the second layer of the skin. The cells of the dermis are far more stable than the cells of the epidermis, so the tattoo's ink will stay in place, with minor fading and dispersion, for a person's entire life. " ] }

why are egrets white?
As in, what evolutionary advantage does being white give them?
