3m9m07 | Swiss gun laws | Swiss gun owner here.
Here's how it works.
You have three categories of guns that you can buy as civilian:
* Notifiable guns / Free weapons
* Mandatory permit guns / Anything semi auto, pump action or lever action (including handguns)
* "Forbidden guns" / Full auto guns
For the first category you just need a simple background check and your ID to buy them. Buying these guns privately only requires your ID.
These guns are basically bolt action and break action guns.
The second category includes pretty much anything that is quick repeating, such as semi auto weapons, pump action and break action. You need to fill out a very simple permit (takes like 5 minutes) where you include your name, address and the type of weapon that you wish to buy (you can fill out up to 3 guns, if you want more you need to fill out another permit).
Then you send this permit along with a copy of your ID and a background check to the police. It's shall issue and cannot be denied unless you have criminal records. After 1 week you get the permit back and you can then buy the guns you wish.
The last category includes anything that fires in full auto or burst mode. You need to fill out a special collectors permit to get these guns, which is fairly easy to get if you already own guns. | 2fb06ebc-5b03-48aa-8980-00501432a2d7 |
3dncja | how bose noise cancellation work | It doesn't deflect the noise, it literally cancels the noise out by playing the opposite noise through the headphones.
Sound travels as a wave. If you play a sound 180 degrees out of phase (aka, the opposite sound), it effectively cancels out and creates silence. [This is a really simple graph showing the concept.](_URL_0_). If the blue wave is noise, and the red wave is what the headphones play, the yellow line is what we hear (silence).
Noise cancelling headphones have a microphone that picks up the ambient noise. With a simple audio processor, it reverses the phase and plays it back through the headphones, cancelling out the noise. | eb441a7e-510e-4e96-a9ad-e37c6ca8f087 |
4be8yh | How come people can't be cryogenically frozen safely as the ice crystals destroy the cell membranes, but sex cells such as sperm are kept frozen for long periods of time yet remain functional? | Sperm is frozen in liquid nitrogen, and the water in the cells is replaced by glycerol (basically antifreeze) as a "cryoprotectant", which displaces the water and does not form the crystalline structure that damages cells.
However, the freezing and thawing process is still pretty harsh and many sperm don't survive. Luckily, there are billions and you only need 1. | 23f64a12-716f-403c-9865-70965a44fdaf |
sgsb3 | Newton-Cotes Formulas | Suppose you want to find the area underneath a curve, but you'd rather not (or are unable to) work out the exact formula. Since area is such a nice geometric idea, you can approximate it by breaking it up into smaller, simpler pieces.
These formula accomplish this, with varying degrees of simplicity and effectiveness. The more complicated the approximation, the more accurate it tends to be.
On a side note, and in a slightly different direction, this theory can be extended a bit to produce shapes (gaussian quadratures) which actually give the exact areas with no error for simple functions. These are much simpler to compute than the actual integral, as they rely only on a handful of points of the function.
I don't know exactly what problem you're having, but this is the basic idea. | 138cd57a-e63f-4fc4-b225-3ef081304f73 |
2ctyyd | How are firefighters able to determine what caused a fire even when the structure or forest is totally destroyed? | For forest fires it is likely that the point of origin isn't as burned as the rest of the surrounding area since it wasn't as strong of a fire. The fire that was close to where I lived two years ago was thought the be the result of an illegal camp fire. They found the origin and found what was a small grassy clearing with some camping gear that wasn't completely burned along with pile of ashes nearby. There was unburned grass between the ashes as the partially burned tent which lead them to declare the camp fire as the source. Chances are that a small stick or ember fell out of the fire onto some dry gras and started a fire. By the time the fire was noticed by the campers it was probably too large for them to put out so they ran. The small patch of unburned grass could have been the result of either wetter grass or change in fire directions. | c144b6e9-783a-488b-be83-b9e228d31162 |
3k059s | How is Ishmael the father of arabs ? | Well if you look at the Old Testament, Abraham had two sons: Ishmael and Isaac. Ishmael, though older, was born to Abraham's servant and as such was not able to inherit directly from Abraham. Abraham freed the servant and Ishmael, and he went on to father many children and became a prophet and the patriarch of Islam.
He's not technically the father of Arabs, he's the father of Islam, the two just tend to go hand in hand | 5a7f896e-4008-46ff-80f5-17be443664fe |
6hnfhx | Why do people shake when they get scared? | Exteme emotions like fear and anger activate the bodies fight or flight response. The body shuts down systems like digestion and decreases blood flow to the extremities. This allows it to increases heart rate and blood flow to the heart and lungs. Also breathing rates increase to get more oxygen into the blood. Hormones like adrenaline are released also. This is a survival response that prepares us to fight harder or run faster to deal with a threat. Part of this process is physical shaking, it's a way to keep the muscles ready for split second action while it's waiting for the brains command to fight or run. This response is largely an automatic response outside our control, andnis just one of several defensive responses we all have. | 14d721e4-152c-497a-bdea-baeb5c4c96e5 |
50z6z7 | Verb forms and tenses (particularly French) | Consider three English sentences.
1. I go to the store.
2. He goes to the store.
3. He went to the store.
Now, all three of those have a differently shaped verb. Sentence 1 has "go", Sentence 2 has "goes" and Sentence 3 has "went". So those are three different verb forms.
Tense (primarily) shows what time the verb was performed in -- past, present, or future. Sentences 1 and 2 both use present tense. "I go" and "he goes" both tell a story about something happening RIGHT NOW (or on a regular basis). So you have two different verb forms, but only one tense (present tense).
Sentences 2 and 3 take place at different times. "He goes" tells a story about something happening right now. "He went" tells a story about something happening yesterday. Here you have two verb form AND two tenses.
With "imperfect past tense" -- the "past" part is a tense, because it tells when the verb took place (in the past). The "imperfect" part might change the verb form (like switching "I" and "he" in Sentences 1 and 2 above) but it does not change the tense. It's its own thing (called "aspect").
Hope that helps -- if not, feel free to ask more questions, this is my forte ;) | 7aa4c802-aa7b-44d0-9318-2b0ba1fb010d |
4cg8jo | There's an aweful lot of craters on the moon, would having a moon base up there be safe? | The moon has no atmosphere or running water, so there's no erosion. The craters on the moon today are the result of basically every single impact over its entire history. Impacts are still comparatively rare. | 6468e011-44a0-44e7-89fe-de6173214a28 |
19vy4j | why people make viruses? | For a lot of them, to make money. For example, many kinds of viruses load a screen as soon as you boot up that says something to the end of "You did something bad...your computer is locked....pay fine at this place to restore your computer" and users will "pay the fine" to get around it.
Some virus authors are simply sociopaths who enjoy inconveniencing and hurting other people.
And then the others are creating viruses irrevently (like NetGear's MrVGina.dll incident around 2007). | b08bc75e-6555-4d4c-9224-f0a5d90f27f9 |
2e9yc3 | Why does starting task manager when my computer is frozen seem to unfreeze it? | Task manager has top priority, so if any other program is hogging up the computer in an endless cycle you can force it to shut down. | e475d7f4-72e5-4da2-a44c-db73b031fda0 |
1hievj | Why is beer not sold in plastic bottles? | Glass has been used for centuries to contain alcoholic beverages because the glass does not react with whatever it contains - wine and whiskey do not age once bottled and sealed, for example. They've pulled bottles of wine out of shipwrecks on the ocean floor and they're still perfectly drinkable after decades of being underwater.
Plastic bottles, on the other hand, tend to react with whatever they contain, and leech certain chemicals, such as bisphenol-A. Apart from the obvious health concerns, this would also affect the taste of the beer in question. | 9783037a-a29b-4151-a4be-964761689d5a |
8md5q2 | How do our bodies “get used to” being in very cold water (e.g. the ocean) after several minutes? | Your brain contains a region called the hypothalamus. This acts like an internal thermostat that controls your body temperature. When you jump in the ocean or a cold pool, your hypothalamus instructs your body to use more calories to raise your body temperature. Of course, it's not foolproof. If the water is sufficiently cold, your body temperature will drop faster than you can regulate it, and you risk nasty side effects like shock and hypothermia. | 93b801bd-42cc-4471-977e-df9c17a4dd41 |
1khydn | Why can't Mexico do anything to stop the drug cartels? | The cartels have tons of money, local support in some areas, and a small army worth of mercenaries. Mexico is up against a very difficult task. America's hunger for drugs is what finances the cartels, and Mexican leaders have repeatedly asked us to reconsider our drug enforcement policies. | 4749d4ba-99ff-44cb-8b14-07907b06dc11 |
65mex7 | When dropping a counter into a slot from the exact same postion on a pegboard/plinko/pachinko style game what is it that stops the counter from falling the same way everytime? | If you could drop the counter into the same position in exactly the same way and the game was in exactly the same state then it would fall exactly the same way. However, you can't do that because even though it may seem like you are doing things the same way on the large scale, on the small scale there are very tiny variations which cause a different outcome.
Think about firing a gun. If you are shooting hundreds of yards away then even a tiny movement of the gun, too little to see without looking down a scope, will cause the shot to land a large distance away. Air movement along the path of the bullet will change where it hits, temperature differences in the barrel, etc. can all impact the result. In the same way the game has a lot of variables which make things happen differently each time. | 2e1524f5-2ed7-430f-bfc4-e086171f8f0f |
2k93wg | why does cold water taste better than regular water? | It's just a cultural thing. The Chinese prefer to drink hot water.
If there are contaminants or bad-tasting substances in the water, though, it'll taste better cold simply because you'll taste it less. | ee998f08-6cff-44e4-bc90-eeaf0092d4e7 |
1i0li1 | What does having insurance on a priceless artwork do? | Priceless is a subjective term used to describe something that is one of a kind and no reasonable amount money can replace. Realistically, every piece of art has a price (what others are willing to pay for it). For insurance purposes, a guarantee of compensation for specified loss, damage, in return for payment. If you buy a “priceless” hand carved art for $1000 and then spend $400 to preserve and display it, you may want to insure it for all or part of your investment. | 6ced5d8f-c8b2-4d0e-8121-50853c901805 |
3m720q | How can a solution to a problem suddenly pop up? | Subconscious mind solves it for you with all of the acquired knowledge and experience. This won't happen if you've no knowledge. | 37d550e8-317d-4aca-ae50-ad93ee7f2a17 |
4gnycm | how do you take an idea to invention if you have no applicable talents? | You need a partner. It is very doable if you are willing to do work. I.E research what materials are needed, how much it will cost. Applicable uses, just research what you can research. Get a patent. then you can do a lot of stuff. You can PM me for more info. BTW don't talk about it too much and just do. You don't want someone stealing your idea.
I also agree with the other people in this thread. An idea isn't worth shit by itself. | 766b8fda-7b24-4a13-8916-6bd50c9b69b4 |
w0z7j | The LIBOR scandal, how it works and how it could have been manipulated. | Massively oversimplified, of course. But okay, I'll take a shot.
Lets say you want to sell something or buy something. How do you set the price if you're selling, and how do you know if you're getting overcharged if you're buying?
With some things this is simple. How much does a Big Mac cost? McDonalds sets the price, and that's what it costs. But for other commodities, it's not so simple. What's the market price for a 1968 Camaro?
Here, the Camaros are owned by different people all over the country or even the world, and the buyers are scattered around too. So if you've got a Camaro in California, a buyer in Vermont isn't necessarily going to know about it or buy it. And if you're looking to buy a Camaro, you aren't going to know that someone across the country just sold one for a given price in Oregon.
What we're describing here is a situation where the market price of a commodity can be wildly variable. Maybe I sold my Camaro to someone who didn't know a lot about cars, had a ton of cash and wanted my exact Camaro for $12,500. But maybe someone else who just needs cash fast to save his house from foreclosure would sell the exact same car, on the same day, for $8,000. So there's two things going on here: the prices on individual transactions can be all over the map for reasons that don't really have much to do with the commodity itself (same Camaro, different prices because of other things like the foreclosure), and there isn't a lot of information (nobody knows what Camaros are selling for around the country.)
Now instead of Camaros, let's consider banks borrowing money from each other. They do this a lot for reasons that don't need to concern us here. Just accept that they borrow a lot of money from each other, back and forth, all the time, often for pretty short terms. What's the market rate for a loan? Again, we've got no central authority owning all the loans to set the price like it was a Big Mac. We've got lots of different transactions going on, and nobody keeping track of them. And it's not just banks. There are all kinds of other institutions lending money to companies, people, you name it.
LIBOR was set up to get at least some sense of the "going market rate" for borrowing money. The way it works is a bunch of London banks call up the British Bankers Association every morning, and they tell them what their best guess is as to what it would cost them to borrow money from other banks. The BBA takes all these guesstimates, runs them through a complicated formula designed to weed out weird outliers (like the guy who sold his Camaro cheap because he needed the money right now) and publishes an average going rate.
It's important because other lenders, all over the world, have no idea what the market in loans is doing, so they look at the LIBOR and go, okay, that's the best figure we've got right now, so that's today's fair market rate for loans, and it gets applied to mortgages, credit card rates, you name it. That includes a lot of things outside the U.K. U.S. mortgages are often based on the six month USD LIBOR (the rate on six month loans in dollars.)
So how you *try* to manipulate the LIBOR if you're one of those London banks is pretty simple. When you call up the BBA, you just lie to them. In the Camaro example, when you call up the, I don't know, the New Jersey Camaro Registry, you tell them "yeah, I just sold my Camaro for $15,000" when in fact you only got $10,000 for it. The idea would be that your phony higher sale gets factored into the equation and now everybody thinks Camaros are worth more on average.
Now whether this actually *worked* or not is still an open question. Right now we know Barclays was doing this, but one bank alone shouldn't be able to move the LIBOR by reporting false data because the system is set up to weed out unusual numbers. It's still not clear whether the LIBOR was successfully manipulated. Doing that would require lots of banks working together. And if that turns out to be the case, the current shitstorm will look like a pleasant sunday picnic. | a245dfcd-699a-46ff-81e2-5bcbd0c22fe2 |
4oq5h6 | Why did everything become so minimalistic? Buildings, art, etc.. | In Western culture, the era from 1916 to 1945 (the two World Wars) marked a turning point. The old European ways did not seem to be working -- that culture seemed to be collapsing on itself in a wave of wars and mass murders. Some artists responded by trying to throw away everything and start with a new, more modern way of doing things, free of the old cultural baggage.
By coincidence, this new simplified style turned out to be very efficient to manufacture or build, especially by machine. So it was both a new fashion *and* a cheaper way to do things. Thus it became very popular. | 3e88c6f7-6e46-474f-8827-61e305c46183 |

2z6bx5 | How is it that SD cards stay the same size but manage to have such varying levels of storage? | Because the actual part the data is stored on is tiny.
Think of it like this; a school buss looks just as big from the outside when it's carrying one kids as it does when carrying 20 kids. | 42277fd5-0011-4833-b725-413fd17e47ee |
36axkb | Why is my inner monologue an arsehole? | I'm not sure what kind of answer you're looking for. We don't know what your inner monologue is saying. It's your own unfiltered thoughts.

8a3bvw | How did people in the olden days construct buildings that were multiple stories high without the use of machinery like cranes to lift and place materials? | Pulleys and inclined planes have been used since a long time. Pulleys to lift loads and inclined planes to push stuff up or down. Much like today's modern cranes, pulleys did the same except using man power. | 3faa9b24-49b6-4ca4-96d3-75de6c14e498 |
6q5hfc | Are Volvos actually safer than other cars?If so why? | Yes they are.

They invented three point seatbelt (and gave it away for free to other car manufacturers, which was very generous move) and side airbags. | 55f66168-41d8-4d7f-874b-a4b4352338c9 |
moz8p | What happens to the "data" that is transmitted wireless and/ or through digital TV. How is this signal turned into audio/video? (It must pass through the human body, it transmits through the walls) | Impossible to explain like you're five, but I'll try my best not to overcomplicate.
It's waves. Waves all the way. But a special type of wave: electromagnectic waves.
Waves all share an interesting characteristic: they only carry *energy*, not mass. Sound is a wave too: when someone speaks to you, their vocal cords vibrate and make the air around them vibrate too. That vibration is passed from molecule to molecule of air, until the ones surrounding the air in your middle ear make your ear drum vibrate. You recognize your ear drum's vibration as sound.
If you're still following me, it won't be difficult to notice that if there are no molecules to vibrate, there can't be sound. That's why sound is called a *mechanical wave*: it needs a material media (like air) to be transmitted.
Electromagnetic waves works like that, but they don't need a media at all. Antennas transmit and receive them.
Light is also an electromagnetic wave, and like any other are considered radiation. But don't be scared because it's not a bad kind of radiation: the bad one is called *ionizing radiation* and basically it destroys your cells. Waves used in telecommunication aren't energetic enough to cause any harm, at least not in a normal daily situation.
EDIT: I hope that gives you at least an initial insight on what's happening all around you. I really love that part of physics and will be glad to answer your questions. Don't be shy and ask away! | d3d01800-d77b-4470-9f61-e88fe9c08144 |
6m8703 | In the recent Nuclear Weapons Treaty, why did the Netherlands vote in opposition? | There are American nuclear weapons stored on a Dutch air base. It was public secret for a very long time, though it was confirmed in more recent years. That sort of thing would be against the treaty. Currently, the government is not taking steps towards removing these weapons / ending this cooperation with the States, so they also cannot really vote in favour of a treaty like that. | 9e2e1e8a-c2ea-4842-ab60-9e51860ea623 |
2jvyxz | Protien Folding and how it relates to Alzhiemers and related conditions | A protein is a very long chain of amino acids. Amino acids are molecules with different shapes and components that can be strung together. A denatured protein has no defined shape and flops around like a piece of string. However, the different amino acids making it up have different *functional groups,* which are the parts of the molecule sticking out of the protein chain.
These groups fall into two main classes. Some really love water, and some really hate it. So if you plop your floppy protein in water, [it will arrange itself into a ball so that all the water-hating groups are surrounded by each other and all the water-loving groups are in contact with the water](_URL_0_).
Then some groups really like to form bonds with complementary groups. So two different points along the protein chain really want to be in contact with each other. This is the driving force that turns a loose floppy string of molecules into something with a definite shape.
However, there's only 21 different amino acids and proteins are made up of hundreds or thousands. So your lysine at position 25 is connected to the glutamic acid at position 39 in the well folded protein, but there's also a glutamic acid at position 59 it can interact with. If the wrong interactions dominate, you end up with proteins that ar ethe wrong shape. And shape is very important for proteins because it affects how well it can bind other molecules, store energy, and perform its function. If it's the wrong shape it won't do anything or might even do actively harmful things. | 6ed56265-3602-4846-9bb1-6e50dd4d47e7 |
3rfmxq | Why does adding water in a beer bottle make the pitch of the sound higher when blowing in it, but adding water in a wine glass make the pitch lower when tapping on it? | The difference is in the medium making the sound.

5r8h1t | Why is our organ of equilibrium located in our ears? | If you want to keep balance you want the system measuring it somewhere that experiences the least acceleration during normal movement and that is the head. The position in the ear is useful, too, as it is further and on opposite sides from the center of the head and therefore experience more movement and in opposite directions when you turn your head which improves signal strength. If it were near you nose it would be more or less just measuring in one spot while the ears are far apart so you have two points for measuring.
It also needs to be close to the eyes as it causes/controls eye movement to compensate head movement so that the image you see is stabilized. | 6548c2b5-7de0-4ede-9f47-a43d7ef45145 |
2c05on | Why do wall chargers seem to charge iPhones faster than computers, xbox... etc | To add to the other replies, current (measured in amps) is drawn by the phone rather than pushed by the charger, and the rating of the charger is how much can be drawn before it shuts down/overheats/burns out.
By default, the phone will only draw a low amount of current (should probably only be 150mA to allow for USB 1.1, but it's generally 500 mA). The charger has a way to signal to the phone that it's able to give more current (connecting the data pins together, putting a resistor across them, etc.), and then the phone will draw a higher amount, generally 1 to 1.2 Amps.
Most phone manufacturers have settled on a de facto standard, but Apple decided on a proprietary standard so an iPhone charger won't charge an Android device quickly, and vice versa. | c2616b53-3038-4019-b34f-bdd5b303505a |
2621rv | If a high-security building like The Pentagon or The White House catches on fire, do firemen have instant clearance to access any area necessary? | This was actually a problem with the 9/11 attack on the Pentagon.
There were reports of unofficial firefighters and military personal touring the site without actually helping. Their motives are still unknown although a few were arrested.
Rather quickly a perimeter was setup and all personal who required access were issued a badge. All that was needed at first was to show ID. Some 8,000 badges were issued. After, a list of people with pages was compiled, sectioned and assigned a leader who then cut back on assigned badges to only those that were critical.
Essentially, a regular fire would have a perimeter and authorized persons setup quickly as the respective counties personal would already be on file and could be issued clearance quickly. A big event like a plane crash confuses everyone for a bit.
TL;DR: Yes, Firefighters have free roam for evacuation purposes but will be quickly screened before being let in, although depending on the situation at hand people could sneak in before a perimeter was set up. | f30c8c4a-a25b-4850-a82d-13409e6d6c04 |
2nt6ad | Why does my hair grow to a certain length a few weeks after I shave my head; but remains that length and never goes past my shoulders even after years? | Your hair doesn't actually remain a certain length.

8bqwxw | What is aggregate efficiency ? | You can figure out how much energy is in a barrel oil, say by burning it in an enclosed system seeing how much the temperature increases. But that is not going to be the same as the amount of economically useable energy it provides.
It takes energy to pull it out of the ground, energy to ship it, to refine it, to distribute it, energy to keep the lights on in the gas station you buy it at, energy lost to the inefficiencies of an internal combustion engine, and energy to mitigate the environmental damage of any of the previous steps. The **aggregate** efficiency of that barrel will be the ratio between the energy it provides, and the energy needed to make it available. | 7e4630a5-ba7b-4c41-9318-45b20bf2ece0 |

People ingest more germs than they think they do, and for the most part, its unavoidable. | da6446b4-9620-42ba-944a-c229c36e65d1 |
2dav9r | From the Psychology perspective and personal perspective. What is depression like? | I think everyone probably experiences their own particular flavor, so to speak. Sort of like pizza. We all can ID what a pizza is and yet each one:
* Has different seasonings in different amounts
* Has different toppings
* Is cooked uniquely
* Has different dough
And so on.
For me, it's a blend of apathy and tiredness. (Depression, not my preferred pizza.)
Think about your normal morning. You get out of bed, shower, brush your teeth, put on some clean clothing, and so on. Most people do all that mindlessly; it's just what one does in the morning. But with depression each simple task somehow becomes a challenge that takes a lot of willpower to overcome.
If you manage to make it through getting out of bed, if you manage to make it through taking a shower -- complete with things like shampoo, because, trust me, each little detail requires willpower and effort -- if you manage to care enough to find clean clothing, and so on, by the time you make it out the door you're just totally fucking drained.
It's like you've just worked an intensive 12 hour shift and your brain is fried and you just want to watch some shitty movie and pass out before you have to do it again.
Except that it's the morning and you've got to somehow muster up the energy and, yes, the courage to go to class or work or whatever. So you (hopefully) show up. At this point you're expected to focus and participate like someone who isn't already physically exhausted and brain dead. That requires more willpower.
**Spoiler alert**: you just used all your willpower this morning! You used it on stupid things like forcing yourself to use shampoo, or forcing yourself to open the closet door to get clean socks rather than just using yesterday's pair. You used it on things that most people don't have to think about.
But none of that matters because excuses don't matter in the real world. "I tried" merits absolute dick; people just care about what you actually do, except for (if you're lucky) people like family and close friends.
Which brings us to the next herb on our depression pie: you often don't feel like you deserve help, and if you do then you're often afraid to get it because mental illness still has a huge stigma. Which means that if you were lucky enough to have people who care in the first place that you're often inclined to push them away.
It's sort of like:
* Being constantly physically exhausted; your body can apparently cause itself to ache and random pains
* Being constantly mentally exhausted; you only have so much mental energy and you've spent it all before you've left the house
* Add a dash of feeling like you deserve it; you can really hate yourself
* Add a side of "because I hate myself I want to be reckless or engage in self-harm"
* Add a splash of shame; you don't feel "normal"
* Add a dollop of feeling like you'll never get better so what's the point of anything
Throw it all together and you've got a pretty godawful pie. Please forgive the excessive food metaphors as I haven't eaten yet. | b3872787-81a0-4d32-adb9-469c920500b5 |
1ulrt3 | How do cell phones only pick up signal from their specific provider? | It's because of the frequency bands; they are regulated by the Federal Communications Commission.
I do not know who shares which frequency in Amerika but here in Germany we got 4 mobile networks (D1, D2, E1, E2) each got a different owner and a different GSM900 frequency range.
* D1 / Telekom 13–49, 81–102, 122–124
* D2 / Vodafone 1–12, 50–80, 103–12
* E1 / E-Plus 975–999
* E2 / O₂ 1000–1023, 0

kyj7z | Australian football | It's a big oval with 18 players on each team. There are three goals made of 4 goal posts on either side of the oval. The teams want to get the ball through the opponents goal posts. You can run and dribble or pass the ball by hitting it (like in volleyball) or kicking it. You can also block and teams can be awarded penalty or free kicks at the goals.
I think that should cover the basics. | 776717e9-380e-4037-843e-2097d1d9f393 |

Civil rights, which the first eight amendments protect, work precisely the opposite way. The ninth amendment basically says that, as opposed to the powers of the US government, citizens' rights are NOT enumerated, and a provision for a specific right should never be interpreted to mean that those are the only rights that a citizen gets to enjoy.

3lw2lk | What drew people to attend the Grateful Dead concerts over and over again? | The GD started their career as a band playing live gigs, most notoriously at the Acid Tests. These were like the very first rave parties, initially when LSD had not yet been made illegal. People would come and drink the spiked Kool-Aid, and there would be a variety of amusements, often including the Grateful Dead (initially known as The Warlocks) noodling around on their instruments trying to make music. They weren't very good initially, and they usually just jammed, rather than playing "songs". The Acid Tests are well described in Tom Wolfe's wonderful book "The Electric Kool-Aid Acid Test".
This started the core of the Dead's following, as some people would follow them around from gig to gig, often taking LSD and dancing and having a great time. It was pretty much a continuation of the Acid Tests. Many of them would make just enough money to survive selling stuff in the parking lots and campgrounds before the shows (or during the shows).
Most people, of course, didn't follow them around like this. But their shows were a great place to be with a mellow community of hippies having fun, listening to good music. A lot of people would go to their shows any time they came near, because it was just like going to a huge party with people who were cool with whatever you were into, as long as you weren't hassling anyone else. Being weird was normal, and being normal was weird.
You could pretty much sit around and smoke dope without much fear of getting busted, because *everyone* was sitting around and smoking dope. Strangers would offer you a toke, and it was only polite to offer the folks around you a toke if you could spare it.
And at their core, the Dead was always a jam band. Sure, they played songs. But some of the best music was what the songs meandered into.
**TL;DR** - The Dead were a way of life for a few people, and a mellow party for a lot of other folks. | b0a1250c-2f39-4f18-acb3-f5fd3f66daa6 |

2dwxho | why is the Mona Lisa so highly coveted- I've seen so many other paintings that look technically a lot harder? | Five reasons:
1. The smile. It was the first painting of its kind to have someone smiling in such a way, so it was sort of a new era.
2. The brush strokes. He used strokes so small, they were damn near invisible, creating a very 'photographic' painting in a time when that wasn't really done.
3. Street Cred. Leonardo Da Vinci was an extremely talented guy, the quintessential renaissance man. He was a genius, and is thus rightly given praise.
4. Time. This painting took four years of Leonardo's life to make.
5. Subject. Nobody's entirely sure who he's portraying, which is pretty weird for portraits. Usually, portraits like this one are commissioned by the person depicted, but it doesn't appear this was for anyone but Leonardo. Is it a girly version of him? A prostitute? A secret lover?

4l46bk | Why does 1% battery last longer? | Battery remaining is pretty much just a guess. Your phone measures the voltage and makes a guess as to how much of power is left. If you rarely or never let your phone run all the way to where it cuts off from lack of power, it will slowly start measuring more and more inaccurately. First it will think 1% remaining is empty. Then 2%, and so on. Eventually, it's estimate of remaining battery is significantly far from correct. When you finally let it run all the way to empty, it will seem to last longer. It thinks it's empty at 5%, so it's shows 1% remaining when you really have 5% remaining. Since it still has power, it still runs, but the estimate is wrong. Because of this, battery drain slows down as it nears empty. | c07f452b-0a92-4b12-93ce-19c9a3916a61 |
3sja72 | What is a CO-OP? | A co-op is any independent organization where people cooperate for mutual benefit. REI is specifically a consumer co-operative, as opposed to a housing or worker co-op. In this case, the shareholders and consumers (shoppers) are essentially one and the same.
If it helps think of Costco/Sam's Club (these are not actual co-ops). You purchase a membership for REI, which gives you one vote. Like shareholders in a corporation, you use these votes to elect a Board of Directors, who then hire the major executives, like the CEO or whatever. Usually in a co-op, unlike a corporation, you can only ever have one vote (one "share") but idk if that's the case for REI. Then the CEO and other executives actually run the company.
A much smaller co-op might be directly run by the consumers/workers/residents themselves. | a24d8237-26d1-491c-be0c-13e8466f910e |

5bont4 | Why do all contests have a NO PURCHASE OR PAYMENT NECESSARY TO ENTER OR WIN clause ? | If a purchase is necessary, it becomes gambling, which is illegal in most states. As such, in order for contests to be legal, they have to include an entry option that doesn't require the entrant spend money.
Usually the requirements are overly cumbersome (physically mail in an entry form, which still requires stamps), so no one really bothers.
It's worth noting that most contests are more to generate publicity than direct sales (though one drives the other), so just having the advertisements and getting people thinking about the product is usually enough. | a57601fe-c703-4b3a-a138-fb396512b439 |

noxyx | the deal with Putin in Russia. Is he a villain or not? | Shame on that guy linking you to wikipedia. this is not a snarky reply sub reddit.
I have limited knowledge on some of his acts, russian politics can be pretty complicated. I will try and give you a basic understanding of why people like him, and why people wouldn't.
**Why would you like him?**
* He took office in a very rough time in Russian history, he pulled them out of a terrible place.
* he installed much needed order to many areas of Russia. Before, russia was rife with incredibly large amounts of crime and corruption (he has not removed it all, though, more on that later).
* he has boosted the russian economy roughly 8% each year he has been in office ([source](_URL_3_)). Halved poverty([1](_URL_0_) [2](_URL_6_)) and increased russias GDP (spending power) by 72%([source](_URL_4_)).
* he instituted excellent tax reforms, helping his people immensely.
* he also brought his people back into the international scene as a s uperpower once again.
Sounds like a pretty good guy, right? Well.
**Why would you not like him?**
* he was once a member of the KGB, the very shady ex-secret police of communist russia.
* He has created an increasing wealth gap between the wealthy and the poor.
* He has suppressed the news from criticizing him, and has held onto power for more than a decade now. A sign that he is growing to be more like a dictator. ([source](_URL_7_))
* despite the fact that he is legally not allowed to own more than roughly 180,000$, it is largely suspected that he secretly owns a fortune well into the billions, which has kept hidden from public view ([source](_URL_1_))
* He is also thought to have rigged the recent parlimentary elections in his country in favor of himself and his allies ([source](_URL_2_))
* Putin has been very effective in keeping **certain** political allies in power, regardless of whether or not they would be winning elections "naturally". While crime has decreased, political corruption has only increased since he took power ([source](_URL_5_))
So, with this information, you can make up a rough estimate on whether or not you think he is a "villain" or not. Ultimately, nothing is that black and white, you should decide for yourself whether or not you agree with him and his ideals. | bf38030a-b3f4-4545-be0b-ccba8d5728af |
29qwlu | Why does streaming from sites like Youtube or Twitch seem to hit my bandwidth harder than playing online video games in real time? | Edited: I wrote without my notes, and overstated size of each frame. Luckily, five seconds of medium def is about 1 megabyte, and the explanation works almost as well]
Networking designer here; my team helped with some of the XBox network code.
You know the phrase, "a picture is worth a thousand words"? Well, if you're watching an on-line (streaming) movie, about every five seconds of the movie about about a "megabyte" of data -- that's like 1 million letters. That's also about how many letter are in a typical book.
If you're playing an online video game, it looks like a movie -- there's flying monsters, and buildings, and spaceships and whatnot. But it acts more like text. Your game is sending back to the central server things like, "I moved forward two meters." And the central server sends back things like, "the toaster will try to kill you".
To see a movie, you have to send the whole movie. For a game, it's like you're sending a description of a movie. That's a lot less data.
And that's why you can play a game and your roommates don't notice, but the video stream kills everyone. | 3ff900e9-35e7-4038-aa4f-c06f9b42d29d |

23.976 fps is 80% – or four fifths of 29.97 fps, which is the frame rate of the NTSC video signal. By slowing down 24 fps *ever so slightly* (by 1/1000), you get 23.976 fps.

3l6uzx | How is Uber legal without following the same liscensing rules as taxis? | Basically, because a taxi is defined as a car that you can stand on the sidewalk and hail. Legally, if you don't provide that service, you're not a taxi. This was upheld in a recent lawsuit against Uber, and the judge ruled that Uber didn't meet the definition of a taxi, since they can only be hailed from the app. They're closer to, say, a limo service where you call and schedule a trip, which generally aren't classified as taxis. | d53a9af6-1ce7-47b4-8aba-4762b1d4ad37 |

Microsoft is less up front about it, and has more of a history of doing dodgy things without telling users. Also, they are an older company, so a lot of their misdeeds occurred before people were as used to getting spied on. | b1579245-fa18-4e61-ad98-0d70847384f3 |

4fqfpw | Why do water pipes not burst after you turn the sink/hose off? Shouldn't the pressure from the water backing up cause this? | Imagine that you have a bucket full of water. Poke a hole in the bottom of the bucket, and water will start pouring out. But if you plug the hole, the bucket doesn't burst from pressure backing up. The pressure is constant, and does not (noticeably) increase when the water stops flowing. The same is true with water pipes: The pressure is caused by gravity pulling water down out of water towers. When the water stops flowing, the pressure just levels off. | 6a91430f-26e2-4a34-a8ec-c843b4c3ada0 |

6mgunv | Why do humans get time suppression during tragic events? | Time appearing to slow down is actually an illusion. The part of our brains that helps us feel emotions, the amygdala, becomes more active during times of stress. This causes our brains to ramp up memory recording, making our memories in the moment of a car accident or similar situation much more dense and detailed.
Compared to our normal memories, it seems like memories that detailed must have been made over a longer period of time than the quick few seconds of the crash would allow. This makes us feel that time slowed down. But it's just memories temporarily being set into "4k recording" mode, so to speak. | 056fd65a-0c41-4252-81c8-2d8e10f881fa |

17bdjc | How does burning happen? Do food-calories "burn out"? | Pretend like you have a jar of marbles. The marbles/jar in this case are molecules/electrons. You start shaking the jar of marbles (applying energy), now let's say you shake it hard enough to the point that some of the marbles break through the jar. (You've applied enough energy to break the bonds.)
The new marble goes flying out and just happens to another jar of marbles which then allows that jar of marbles to get excited and release some of it's marbles, and the cycle continues.
Now pretend like you packed the jar full of marbles, it's now going to take more energy to get the marbles to break free (boiling and melting points of various compounds). Now pretend that the marbles are all various colors and sizes (different compounds), and that different colors of marbles are attracted to each other while others aren't.
So as you're releasing the marbles by applying energy, they come off with various amounts of energy and impact their surrounding marble and marble jars accordingly. Now as the marbles are moving round, they can also break into smaller marbles and join up with other marbles to form bigger ones.
Burning something sends a lot of energy into the other marbles and breaks them apart into other sized and colored marbles that no longer have the functionality of it's previous form. | 946540bf-2226-4b09-b79d-e3e333ffc718 |

33gxcj | Is it possible to drink water at a constant rate such that you can just keep peeing indefinitely? | No. You can drink in excess to the volume of water you excrete, and this can in fact even be fatal if done excessively enough. The result is that your extra-cellular fluid will be low in solutes, and osmosis will shift it into your cells, causing swelling in (among other places) the brain, what is sometimes called water intoxication. Sufficient swelling can result in death. | 2dfefa3d-eecb-43c4-8989-ccbea2f3a20f |

5gr2sx | Why do windows sometimes act like mirrors | Glass allows most light to pass through it, but because it's still naturally reflective ([similar to a mirror](_URL_0_)) you will always have some light reflected back. If the light coming through the window (from outside) is brighter or more intense than the small amount of light that's reflected (from inside), you'll see the light from outside. If it's dark outside, you will see the light reflected from inside. | d2b961e6-e56b-477a-a002-0d669748c0ce |
436yap | What is going on with You Tube? All sorts of fairly popular channels are being deleted, losing monetization, or having constraints placed on them and seemingly out of nowhere. Is there new management, broken automation, or something else? | I'm not sure if this is what the OP meant to imply, but the limitations aren't being placed on specific channels, but are rather sweeping algorithm and policy changes that affect everything.
The two that seem to be causing the most grief are the switch from a per-view monetization plan to a per-minutes-watched monetization plan (although this happened a long time ago in internet standards) and the fact that their content-ID algorithm gives false flags to videos ALL THE GODDAMN TIME. When a video is flagged for copyright violation, the monetization is automatically disabled for that video. There have been cases of things like the *sound of rain* triggering the algorithm to flag a video for copyright infringement.
tl;dr a combination of seemingly benign policy change and bad automation

5gv9uy | Why do some sudden noises scare the crap out of us, while others go nearly unnoticed? | (This is purely from what I understand about the flight or fight response; I have done no research into whether this is an accurate explanation so take it with a grain of salt). If your ears cannot detect or is not expecting a specific sound the brain defaults to "this sound is foreign or out of the norm so it must be bad" and releases some adrenaline to help you fight the the threat or go away. In the days of primitive humans, a foreign or unusual sound usually meant danger, so the brain evolved this response to help fight or flee from the perceived threat. Since your brain knew the second time around the sound wasn't a threatening sound or you might have been expecting it your brain simply ignored the signal to release adrenaline, since the brain wants to conserve as much energy as possible; again this comes from speculation and my limited knowledge of how the human body actually works; fellow redditors free to correct me if I have misunderstood or misinterpreted anything. | 0a503eab-5617-4829-a861-20c846ef49d5 |

1xjmtr | Why are things like countries referred to as females? | Other languages have grammatic rules in a way that differentiates male, female, and middle form (and a plural form of a singular object).
Each noun belongs to one of these forms. Doesn't matter if it's a living thing or just a thing. And doesn't even matter if the object is of male nature or a female nature. It has more to do with a system or a classification, mostly with the endings of words. So that everything is structured nicely.
It really has more to do with the phonetics of the noun. Not so much with the meaning.
In such languages, the form of the noun also affects adjectives, verbs, etc. used with the noun depending on the noun's form.
So for example, if the word "phone" is male and the word "car" is female, then in phrases: "nice phone" and "nice car" different forms of the word "nice" would be used.
That's why kids growing up in such societies are taught how to differentiate the forms of nouns. So that they can use the correct corresponding forms of verbs, adjectives, etc.
This carries over to names of countries among other things.
From that, English-speaking people exposed to foreign cultures grab snippets of those languages/cultures, translate them literally, and use them in a way that no longer makes sense, when used in the English language.
And then, some English-speaking people push it even further for dramatic effect. "Ain't she a beauty" -- when talking about a ship, for example.

47i1is | How to pay off students loans? | Interest is a percentage that you were told when you took out the loan, and every month (or year or some other time frame) that much percent of the amount you have left to pay is added to your bill. To pay off the loans you probably have to contact the company you took out the loan from, look for a contact number on the monthly statement you receive for the loan in the mail or online. | e2393155-094d-48fc-b35b-2bde92fd08bd |
2bve43 | Why can't humans see in the dark? | Our eyes are stimulated by electromagnetic radiation in a specific range - we see the "short" end as violet, the "long" end as red, and everything between as various colors of the rainbow. Any shorter wavelengths start moving into the ultraviolet range, which doesn't stimulate our eyes. Same with wavelengths longer than red - they go into the infrared range.
So tl;dr: Your question is backwards! It's not that humans can't see in the dark - it's that humans have defined "dark" as the absence of light in the visible range.
Edit: Technically, it comes down to the _URL_1_ (s) and _URL_0_ (s) in our eyes. We have 3 types of cone cells that respond to light in the visible range as defined above. If we had say, a 4th that could detect UV light, then we'd see an entirely new color beyond violet. Some animals can see far outside of the range that we can, so "dark" for us might not be for them. Rod cells are more sensitive to light and aiding in low-light vision, but we simply don't have as many as some other animals, and our eyes don't let in as much light. | f2d913eb-f9db-4fa5-9df2-756ac799bb6c |
mvzvq | Why is the patriot act viewed negatively? | The purpose of the act was to deter and punish american terrorists. In reality it was used by the FBI to ignore the constitution and things like 'probable cause' to investigate people unrelated to terrorism. This included, drug traffickers, homeless people, visitors to las vegas, and a webmaster regarding copyright infringement.
> One criticism of the Act is that "other purposes" often includes the detection and prosecution of non-terrorist alleged future crimes.

Git is a version control system that acts as a repository for your source code. It has features like version history, branching and merging, code rollback, all the things you need to properly handle large coding projects.
Git is one of a number of version control systems, and it is one of the most popular (if not THE most popular). Other examples include Perforce (popular with game development studios because it handles binary files much better) and SVN. | dc304ef6-417a-41b2-922e-960668b815fb |
3c23y0 | Why are older people generally more conservative? | There are several different things at play here. I'll try to cover the biggest factors.
1 - The older generation *already won*.
Think of the world as a thermostat, with the temperature it is set at being the condition of the world regarding everything from social issues to economics to politics and beyond.
One generation comes along and sets the temperature at 55 degrees F. Their children think that the temperature should be 63 because of changes in the outlook of the world or technology or something else. But the problem is - the first generations *likes* the world at 55, they don't want it to be 63 because they are happy where they are.
This happens as each generation is born and becomes dominant, the thermostat keeps getting set at or close to the "ideal" of that group... and the younger group always thinks that it should be different because... well they are different people.
2 - Older people have something to lose.
When you're 22 with no spouse, no kids, no house, no mortgage etc. it is very easy to say "the world should be different and I'm going to work to change it". There's no real consequence to failure since you already have basically nothing.
But fastforward to 42 and suddenly you might have a spouse... a few kids, a house and mortgage, maybe a job where you are working your way up the ladder... in short - people depend on you. You can't just drop everything to protest some social issue... you have work in the morning and if you don't work you can't pay for the bills and your family is in trouble. | 4a607643-6a8c-406f-8ddd-d6439f3fba7e |
7609ai | What does the common person seek to gain from denying climate change? | Howdy! It's my belief that the crisis is overblown. I do not deny these things:
1) climate is changing
2) we are part of what's changing it
Those are the things that there is scientific consensus on. The things that I do not find as much consensus on:
1) the actual percent contribution we have on climate change
2) the outcome of what will happen due to climate change
3) actual solutions to slow / reverse climate change, assuming the outcome is devastating like people say
Here are reasons why I question these things:
1) reports that data sets were scrubbed / information was cherry-picked
2) it's extremely suspicious when climate change spokespeople claim the science is "settled" which basically goes entirely against what science even is. It indicates to me that these people (Neil deGrasse Tyson, Bill Nye, etc.) are motivated politically rather than scientifically.
I do not intend to insult anyone or anger anyone with this post, I only post this with the intent to possibly shed light on the other side of the argument. Almost nobody denies that the climate is changing and that we are a part of it, it's mostly a disagreement on the severity / solution and a distrust of the political spokespeople who attempt to squash further investigation by berating everyone who disagrees with them.
Feel free to downvote me and trash talk me all you'd like, I do not intend to reply to this post if the response is as overwhelmingly negative as I expect it to be.

3zx24l | how do exploding bolts work? | The application I know explosive bolts are used for is aerospace engineering: they are used to separate rocket stages since they are lighter and much more reliable than other mechanical separation methods, especially in a zero-G environment. You can see that [here](_URL_0_).
Explosive bolts contain explosive charges in a specific pattern, usually on the circumference of the bolt, that are wired to a remote detonator. The wireless signal is received by the remote detonator and through the wires reaches the explosive and ignites it. The bolt is often designed to have an intentionally weak spot where all the energy from the explosions releases and snaps the whole thing in two. | d5ff15ad-937c-4a01-9476-72d60357f660 |
5gl9z4 | What is it about the color black that absorbs light and converts them into heat? | it's physics. and you got it the wrong way 'round.

that light carries a certain energy with it which gets absorbed, which is then converted to thermal energy aka heat.

4ymwh6 | What all exactly did Edward Snowden reveal? | Strictly speaking he only "revealed" details on US foreign surveillance. Prior to the Snowden leaks, it was widely assumed that the US was spying on pretty much every other country (and that they, in turn, were spying on the US). What Snowden provided were concrete details on how exactly the US was doing that.
For example, prior to Snowden the German government could assume that the US was spying on it, but didn't know quite how or exactly what information the US was able to get. After Snowden it was revealed that the US had tapped more or less every important phone line in the German government and was aware of the full contents of many conversations/documents that the Germans had previously assumed to be secret.
This extends to every country in the world. Post-Snowden, Russia/China/India/Pakistan/Iran/ect... all had a publicly searchable database handed to them that they could use to check to see how the US was spying on them. Its also assumed that China and Russia gained full access to Snowden's hard-drives, and so may have gotten even more information on US spying efforts than was publicly released.
The other half of Snowden - and the stuff you tend to see talked about online - is the domestic surveillance stuff. None of those programs were secret, the specific details of how they functioned may have been but all of those programs were well known in the legal and law enforcement communities and had been *extensively* litigated throughout the mid-2000's.
All Snowden did as far as those programs were concerned was to raise awareness of them outside of the legal/law enforcement communities, but nothing new was actually revealed.
But to sum those programs up:
1) Wiretaps. Prior to Snowden most laypeople assumed that wiretaps still involved a person going out to your house and placing a bug on your phone line. Post-Snowden people became aware that telephones are all digital, and that a wiretap is just the phone company approving the call being routed to a law enforcement computer in addition to its destination.
2) Private partnership with law enforcement. Prior to Snowden laypeople assumed that companies like google completely ignored your search requests or the contents of unencrypted emails sent through their services. In reality they parse and use that data extensively for advertising purposes. If their advertising algorithms detect certain red flags, such as if they see someone repeatedly searching for a known Islamist forum or you have a long email conversation about how to build pressure cooker bombs, most companies will voluntarily forward that information on to law enforcement.
3) National security letters. The US can get a special type of warrant related to foreign activity being conducted within the US. These warrants are not public, unlike all other warrants, and come from a specially formed court. This court is authorized by Congress, approved by the President, and has been ruled constitutional by the Supreme Court. There are very strict guidelines for when this court can issue a warrant, and is extensive oversight of the court within all 3 branches of government. It also produces a relatively small number of warrants each year. But again due to the nature of how it works only Congressmen/the President/judges at the appellate court level and above have full access to the warrants it produces, though you could challenge a warrant issued by the court if you were ever charged with a crime using information obtained by one. Though typically the judge would review the probable cause for the warrant in private and would not turn it over to you, which is actually not as uncommon as most people believe. (For example, lets say there is a known information who provides information to the government that leads to a normal warrant being issued against you, if you challenged that warrant you will frequently not be told the name of the informant, even though the warrant itself is public).
Edit: and I'll put a final note that causes confusion a lot on the internet. Part of how US foreign spying works is that a substantial percentage of worldwide internet traffic passes through the US, even if neither the sender or recipient is in the US. It will sometimes even pass through the US despite being sent to two people living in the same foreign country. The US takes advantage of this and will read the full contents of any such communication that passes through the US.
People frequently get confused about this and think that this also applies to wholly domestic traffic, which it does not. However, there are *very extensively litigated, limited circumstances* under which the US government can view traffic that originates in the US with a foreign destination, or which originates outside of the US with a US destination without a warrant. Exactly what those circumstances are is beyond an ELI5 but suffice to say they do not affect the overwhelming majority of Americans. | 33886c69-9d76-49f3-a566-cb317f6bbb7c |
