How is something approved/guaranteed to be a law of science rather than a theory? What sort of process does it go through? | With the *scientific* method, you start with *observations* about the world. Once you think you've made sense of these, you create a *postulate* that predicts what will happen in more tests. After sufficient testing on a number of different situations, your postulate becomes generally recognized as accurate & becomes a... |
Why does my tongue hurt after eating too many sour things? And why doesn't this happen to everyone? | Don't ignore the pain either I love sour skittles but after eating a whole family size pack I burned a hole on my tongue that made all food painful for a day |

How can a US citizen get dual citizenship in another country? | Why would you need to be a citizen? You could live and work in any of those countries indefinitely as a permanent resident while retaining US citizenship. Anyway, dual citizenship is typically something you acquire either at or near birth. In the [United States], obtaining naturalization in a foreign state upon one's o... |
why do we close one eye while aiming | Because when we're getting input from both eyes, it's more difficult to look down a straight line. Even if one of your eyes is aligned, you will be getting input from the other eye at an angle. If you close one eye, you can look exlusively down a straight path. |
Why isn't being a juror a career? | Firstly, it would be a lot more expensive. In Canada, a juror gets around $50 per day. Since they have university degrees, I imagine that a professional juror would receive a salary of at least $60,000 per year. When you do the math, a professional juror is three times as expensive. That's just the wages, you have to i... |
Is a startup just as easy as it sounds? Find a group of committed buddies with an idea, and simply do it hoping to make millions? | The biggest challenge is getting funding. You have to find someone who's willing to to pay you and pay for all the company's expenses up until a time at which the company is self-sustaining. Starting a company costs a lot of money, and requires a monumental amount of faith that the project will actually produce results... |
Why is it that sometimes when I drive with my windows rolled down, a painful helicopter chopping sound is produced? | Aerodynamisist here. tl:dr Its like when you make a milk bottle hum by blowing over it except you're now inside the milk bottle, sort of like being in a drum when some one hits it. The other answers are correct, it is a helm-holtz resonance, the same thing that makes milk/beer bottle hum when you blow sideways over the... |
How can babies sleep in awkward and uncomfortable positions, without showing any symptoms of pain, such as a stiff neck or back that adults would normally show? | Muscles get tighter and less pliable over time. Babies have outstanding range of motion because they haven't had time for their muscles to pull their skeleton into specific positions. Squatting is the classic example of how a body's flexibility changes over time, with the bones and proportions staying the same, range o... |
Why do MLB players now wear their pants long, loose, and sloppy at the bottom? | I personally hate it, too, and think that everyone should have to wear their uniform like Ian Kinsler and Curtis Granderson. It's a classic look. The long baggy pants look lazy and half-assed. It takes away from the overall look of the uniform which should include knee britches, long socks, and stirrups.This episode of... |
Can something go "below" absolute 0? | That wouldn't be possible. 0 degrees K is as low as you can go. It can't get any colder, as all motion as stopped. |
How do prank shows get away with impersonating police officers in public? | I may be incorrect, but I believe that when the laws say you can't impersonate a police officer, that means you can't enforce the authority of police officer, which means you can't arrest someone, or pull someone over, etc. You are allowed to dress like a police officer and interact with the public. On some prank shows... |
What is laughter and why are things funny? | I used to have it bad when very young, I would laugh for hours, when my parents looked at me like I was crazy it only made it funnier, when in the laughing mood anything was like adding hay to the fire. Still hits me sometimes, I stare in the window of the buss, some crazy thought hits me, I giggle to myself. Pressure ... |
Evolution/Speciation Question- Why do extinct species don't come back through evolution? | > if the entire human race was wiped out , given enough time, wouldn't evolution take its course again and have the same mutations that produced humans at first to re-occur? No, because the ancestral ape that humans evolved from no longer exists. |
Why do most animals know how to swim instinctively, but Humans do not? | Actually, human babies can swim before they can walk. The reason why many humans can't swim when they get older is because of being, for lack of a better term, over-educated about the dangers of drowning. A pre-teen or adult getting into the water for the first time knows about drowning, and realizes they're doing some... |
How do mental disabilities/disorders improve one's senses? | Are you talking about a person with something like Autism or Asperger's? The problem with the question is that there is an assumption that all people with these disabilities are smart. However, there is a High-Functioning Autism, [which is the one most people are familiar with , where they are able to function and typi... |
What is happening when people experience voices in their head? | I use to run an interprofessional club at school, one of the workshops we did was about mental health. We did this one activity where we had a bunch of iPods with this audio stimulator to somewhat understand or experience the voices in your head. We had members walk around the school, speak to friends, get food or a co... |
The pros and cons of consolidating student loans | If your in England and with the SLC there is no pro at all other than having that extra bit of money each month . The interest rate is stupidly low and is eventually written off. Best thing though is that it doesn't count as debt when applying for anything nor do they show up on credit reports. No use to you I assume b... |

Why/how did Rage Comics die out so fast? | They were around for a long time on other sites. By the time they got popular, they were already dropped by most content creator sites again. They also got so popular that most of the content was just pretty big shit by people that didn't understand what they were doing.Rage comics have come and gone over years. The in... |
If I was thrown into the future, how far would I go before I could't understand "Future English"? | The evolution of English had a lot to do with geopolitics. England being invaded by foreign powers, notably the saxons and then the Normans who basically combined their languages to form the basis of English. But that's when English was pretty limited to England. If the UK had been conquered by Germany for example then... |
Why are alcoholics generally expected to stop their addiction cold turkey but other drug addicts are weaned off of theirs with other drugs? | Mainly because other drugs have those substitutes to be weaned off to. Not to mention, most other drug addicts do quit cold turkey, they go to a facility, or stay with friends and family, and suffer through the withdrawals, it's an incredible minority that uses things like methadone. |
How can I get over shyness? | Sounds very much like you have social anxiety, it's quite common , I strongly recommend seeing a therapist or getting councelling for this. |
explain how 9mm can be smaller then 7,62. | Imagine someone took a mini-sledge hammer and slowly brought it down on your head. It would probably hurt a bit, or maybe not at all. Give that same person a 16-ounce Estwing finish hammer and let them hit your head as hard as they could. That's why caliber isn't the only determinant of the danger of ammunition. For in... |
Why are many important historical artefacts locked away and rarely displayed even though they are very well protected (climate control boxes etc)? | Most museums do not have the floor space to put their entire collections on display, nor the money to expand it--and very special artifacts bring added costs with them. Keep in mind that museums don't just serve the general public. It is common for them to employ researchers and cooperate with universities--making the ... |
What is happening in Ferguson, MO? | The Missouri governor has activated the National Guard which many people suspect he wouldn't be doing unless the case against Darren Wilson was going to be dismissed. The evidence that supports Darren Wilson's version of events has increased to the point where a dismissal is actually likely. To be clear, however, no of... |
why bankruptcy is legal. | Bankruptcy exists because we want there to be a bottom to the pit of poverty. Without it, we'd basically have slavery. And bankruptcy has protections built in so that people often can't gain from it. First of all, some debts survive bankruptcy, including student loans. Liens survive bankruptcy, so that prevents you fro... |
Why is it rude to ask someone their salary? | Because, at least for men, part of your worth is measured in how much you make. It's like asking someone how big their dick is |
Why don't humans' bodies explode after they die as whales' do? | Because we take efforts to not allow that to happen. Human remains are almost always embalmed or cremated shortly after death. Either way there isn't a catastrophic gas buildup like that. |
What's the internal fear we get when are (in astronomical terms) comparing the size of our planet to massive stars? | This is a nuanced question that could be answered to an extent by almost any intellectual field. My take on it is that humans are a very definite species, we need to things to be clear and answered and we need meaning. Not meaning in a romanticized sense. More like 1 dollar is worth x of another currency, it rains beca... |
How do so many countries commit war crimes, and yet there seems to be little action against it? | Leaders don't want to start justice-fuelled conflict because it's expensive and won't get the people on side because the war crimes are kept a secret anyway, so the public don't see them as a problem. The thing you've got to remember is, nothing in international politics is humanitarian.There is no global government, a... |
Why isn't Google Fiber available in more locations? What is preventing them from expanding? | Google really did not want to be in the ISP business. The incredibly lousy speeds of US internet providers was threatening to crimp the businesses they do want to be in, so they decided to try to do a demonstration to embarrass other ISPs. The other ISPs didn't actually do anything in response. Presumably Google is now... |
Why can't the human body naturally repair eyesight? | The reason we do not regenerate parts of the eye are because once the structure is in place, it technically doesn't ever need to be rebuilt so there is no framework for repairing the incredibly complex composition of the eye. Usually in a case of myopia or hyperopia it seems to be a genetic abnormality but I'm not sure... |
What causes brakes to lock up when stopping a car too fast? | To stop your car, there's two spots of friction going on: the brake pads against the disk or drum, and the tires against the road. Normally, your brake pads are only tight enough to slow down the rotation of the tire, so the tires keep friction against the road and you can still control the car. When you slam down hard... |
Airports. Who owns them? Who coordinates them? Where do the airplanes stay when they're not in use? | Who owns them: usually a public entity . The state/city/etc. usually delegates managing the airport to a private company. Managing the airport means maintaining infrastructure and convincing airlines to use them, then bill airlines for that. This includes runways, facilities, counters, storage space, luggage belts, gat... |
Why did studios switch from blue to green screens? | I'd say that the particular shade of green in use now has been determined to have the smallest number of corresponding same-colored objects in modern movie sets and costumes.Source: _URL_1_ |
What's happening in Syria and why isn't anyone doing anything about it? | The Arab spring that came last year was an attempt to overthrow corrupt dictators. In North Africa the people were successful, in the more Arab countries the dictators were successful. Except in Syria, there the people and the dictator were so evenly matched that neither could quite defeat the other. Over the last year... |
How is digital information stored (in computers, memory sticks etc.) without a power source? | Flash memory, for example, is based on floating gate transistors, where the gate of the transistor is insulated. That means any charge you collect in there, will stay there. In ELI5-terms, it's like a bucket that holds electrons. |
The difference between AM and FM Radio | Let's shift radio way up into visible light. We can also imagine that things like houses and cars are made of glass, you can kind of see through them, unless there are a lot in a row. So the radio transmitter is just a really bright lightbulb on top of a really tall pole. We can very quickly change either the colour or... |
Why do warring armies not kill each others medics if they can avoid it? Wouldn't disallowing their opponents wounded to be helped be a benefit? | It's part of the rules of war. It also makes sense - lots of your opponent's effort is spent taking care of wounded soldiers, so not interfering with this is good practice. Even if they do save the life of the wounded soldier, it is unlikely that he will again join the fight. A side whose actions were based only on har... |
How do so many people who post obviously copyrighted video on YouTube have YouTube partnerships (and therefore ads on their videos)? | Fair use. You can use copyrighted material in your own material, even for commercial use, if it falls under fair use. Fair use is things like review. That's how game reviewers, movie reviewers, TV show reviewers, etc all show copyrighted material and then sell their review. |
Where does all the power go that was produced and is in the grid but not used? | There are plenty of different answers and it's handled differently in different areas. The best method is to predict well and be able to tune with ammount produced. With some quite poor exceptions, all the energy produced has to be consumed at the time or there eill be plenty of waste.In sweden we've got lots of hydro ... |
if antibiotics will eventually stop being effective, will antibacterial products like bleach also stop working? | It's very unlikely. Antibacterial products like bleach and alcohol are actually in a different class than antibiotics known as disinfectants.

All popes from 1523 till 1978 were Italian and then there were three non-Italian popes in a row. Why? | One of the reasons was because you had to be in Rome to vote for the pope and getting there from let's say England or Poland would take months. |
How do magnets exist without violating the law of conservation of energy? | Applying a force doesn't require energy. You don't spend energy just standing on the ground, despite the force of gravity. Energy is force multiplied by a distance traveled in the direction of that force. If you have two magnets held apart, they have some potential energy, if you have two magnets stuck together, you ha... |
Are more serious/strict people less affected by levels of pleasure such as Serotonin and Dopamine from the Brain? (X post from AskReddit with no responses yet) | It isn't really possible to say that complex personality traits are due simply due to elevated levels of serotonin and dopamine. For example, some individuals with anorexia have elevated levels of serotonin in regions of the brain that have the 5-HT1A receptor . I'm not sure that their elevated serotonin levels are cau... |
why is communism hated? | Communism at its core is everyone agreeing to share everything. Take what you need and make what you can. But people don't share well. People are lazy and jealous. People will take more than they need. On a national scale communism would never work. Too many people would not play along. This is why communist revolution... |
How does reincarnation work when the population is constantly rising? | I took a comparitive religion class in high scholl, so it's been a while since I'lve studied Buddhism, but from my understanding new souls are always being created and old souls are always reaching nirvana. There was also a metaphor I remember being told where imgine your existance is a cup of tea. When you break the c... |
Why do so many employers release schedules every week instead of having people work on the same days? | * Demands change. Businesses don't do the same amount of business every week. * People's schedules change. If John A takes a vacation, I need Patty B to cover his area, and I'd need Jamal C to cover for Patty but Jamal can't cover every day so I need Marissa D to come in a couple days. |
Gypsies and why Europeans hate them. | I'm from Scotland and everyone here hates gypsies. You can tell right away when you see one as they all seem to have strange outdated haircuts, talk in a nonsensical english/irish accent and swear a lot. To say that they are all thieves may seem like a stereotype but it couldn't be more true. Where I stay there used to... |
Why is one bad movie so bad for an actor's career? | If you buy a sandwich from Subway and it's ok, then nothing much happens If you buy a sandwich from Subway and it's horrible and gives you the shits, then you tell everyone you know to avoid it |
How can fast food companies (McDonald's, Burger King, Wendy's etc.) make a profit on a $0.99 cheeseburger? | There are only two scenarios at work here: 1. The COGS for the burger is less than 99 cents, and the company makes a profit each time it sells a burger; or 2. The COGS for the burger is greater than 99 cents, and the company loses money for every burger it sells. So how does the company make money? It counts on the fac... |
Why do people go to those places to cash a check? Why not go to a bank? | Because many banks don't like to set up in bad neighborhoods, and the people living there can't really afford the time or transport cost to go to a good neighborhood where there is a bank.A lot of reasons -Chexsystems - This is a bank "credit score" system that reports if you owe money to another financial institution.... |
Is there any hard evidence that GMO foods are harmful? | No actual proof that the GMO's themselves are harmful though they may enable the introduction of harmful level of herbicides and there possibly may be long term consequences that we are yet unaware of, but no evidence as yet - _URL_0_ |
Why are there so many atheists on Reddit? | * The internet in general, and reddit in particular, skew young, liberal, and technically savvy. That demographic runs towards atheism.* /r/atheism is probably the largest and most active atheism forum in the world. It attracts atheists to reddit.* Between the two, reddit has attracted enough of a critical mass of athe... |
[Meta] I think people are forgetting what /r/explainlikeimfive is for. | I think the point of this subreddit was to provide a place where any question, no matter how simple or complicated, could be answered in layman's terms, with no need of an expert at hand or further explanation. The whole 'five year old' description thing is simply a metaphor. In any case of discourse, I think it still ... |
Why is sugar free soda bad for me? | Too much phosphoric acid is one contributing factor. If you get too much phosphorus compared to the amount of calcium you're getting, that could lead to bone loss. [Web MD] |
Is ISIS actually a huge threat or is the media just blowing it out of proportion? | What's really scary is looking at the time frame ISIS has been in the news, and compare that to the amount of deaths cops have committed on our own soil, within that same timeframe. You don't have to include justified shootings if you don't want to. Wether it's getting your head sawed off, or getting tazed to death whi... |
How come there are millions of users on reddit, but relatively "successful" posts only get around 4 figure upvotes? | If I'm not wrong, the weightage of each vote drops as the karma increases. So if it's alr at 3000, adding another up vote probably brings it to 3000.01. This is so that the front page won't be dominated by a certain post with like, 20000 karma or something. |
how is the green monster legal in baseball rules? | It's harder for both teams, it's not like the Boston Red Sox have any advantage over the other teams. The real answer though is that baseball started quite a long time ago before sports were huge multi billion dollar industries. The teams didn't have the money to build new stadiums that all had the same size/shape play... |
Who decides which person "wins" a presidential debate? It seems arbitrary to me. | The news networks have panels of journalists and/or pundits who state their opinion on which candidate did better. They also generally have some focus groups made up of moderate or undecided voters. These voters pick which candidate they thought was more effective and the network says that he won the debate. This metho... |
How did _URL_0_ cost $634,000,000? That seems a bit much. | Here's the real answer: it didn't. 634 is a number that people with an agenda throw around. It cost closer to 100million. Before anyone accuses me of being some liberal apologist. Here's a link from Glenn Becks site, the Blaze._URL_3_ |
If Reddit's platform is open and Reddit Enhanced Suite is so popular, why is it not part of Reddit? | I think it's just an injected and run javascript file. It probably uses some ajax, using up more bandwidth. It's fairly complicated to use, and to configure personally. |
Why do people pace around the room when they make phone calls? | TLDR:Because you can't read the other person's body language. Because subconsciously your mind is anxious. Only a small part of our communication is verbal, the rest is various body language.

Why do you feel extremely hungry after you wake up sometimes, even if you ate a lot before sleep. But don’t if you were awake the same time with nothing to eat? | Taken from another thread that asked the same question: The amount of sugar in your blood stream has a big impact on how hungry you are. When you eat something with sugar your blood sugar immediately rises. As time passes your body uses that sugar for energy and your blood sugar levels get low. This causes you to feel ... |
How can a signature prove anything? | You can claim that, but there are signature experts who are pretty good at spotting different people's handwriting. But in the end, a court also relies on common sense. If you're the only one of a companies 20,000 customers claiming they forged your signature, the court is probably not gonna believe you. Its evidence i... |
Why does uninstalling something take seconds while installing something can take hours | In Windows you have a Master File Table, a long table in the beginning of your hard-drive that details where each file is located on the drive it self. When you're installing a program you have to populate that table and also write all the zeroes and ones to the hard-drive. The computer also have to search through the ... |
Why wouldn't a flat tax work for the United States? | The lowest tax bracket for individuals is 10%. The lowest corporate tax bracket is 15%. Herman Cain's plan was nothing more than a massive tax cut for weathly individuals and big businesses, to be balanced out by a consumer sales tax of 9% that would hit low-income families and small businesses in a very detrimental wa... |
why does time move in one direction only ? | It doesn't. That's just how we experience it. *Drops mic*", '[Sixty Symbols- Arrow of Time] might help you out. |
Why do bananas turn brown? | It's an oxidation process that takes place when the banana is exposed to air . The fruit reacts with the air and produces brown pigments. This chemical reaction can not be avoided, however, it can be slowed down. For example, rubbing a thin layer of lemon juice, protects the layer of fruit and minimizes the rate of oxi... |
Why does sending a picture via Messenger lower its quality so drastically? | Messenger apps have built in compression designed to save you data because most cell phone services have some kind of data limit or cap. So when you send a picture, by default, they will compress the picture into a lower quality format that they've deemed an appropriate compromise between file size and picture quality.... |
If animals can distinguish us from our smells, how do they not get confused by the smells of our soaps/colognes/deodorants/etc? | To an extent, they do. They could identify you from further away by smell if you didn't wash. |
Why is it when you speed up a voice it becomes higher pitched? | It's to do with the frequency. If you picture sounds as a wave. A higher pitched sound vibrates more than a slower sound. Therefore speeding up a sound causes it to vibrate more quickly, changing the pitch. The same is also true in reverse. If you slow a sound down, it vibrates less and lowers the pitch |
How do people have diet problems, like being lactose intolerant, vegan, gluten free, etc... when their ancestors survived off of these foods? | Well, for lactose in particular: We didn't evolve to drink milk in adulthood. The idea of capturing and breeding other animals, in part, to harvest their milk is a pretty new thing in the human experience, evolutionarily speaking. In the bygone days prior to agriculture and domestication of animals, only small children... |
Why are the symptoms of a cold worse when a person is about to sleep? | Your immune system is remarkably energy inefficient. It takes huge amounts of chemical and electrical resources to fight an invasion. By the end of the day you've done more than you realize simply sitting there and are extra worn out. It doesn't help that we also tend not to stay properly hydrated and eat well during a... |
why objects in mirrors are closer than they appear? | Flat mirrors typically reflect the same area as they take up, as if you were on the other side looking through a window. So things appear normal size. Mirrors curved outward show a wider angle, so show even more things in the same space. Because they show more things in the same space, each thing usually appears smalle... |
Can you make another internet? | The internet is a lot like a road. It is a path for data to travel on from one place to another place.

If you've got a router at home with several computers connec... |

Why do so many people have peanut allergies? | It's not really something that would just go away with natural selection, we have medicine and technology and awareness now. Way back in the olden days, if you had a peanut allergy, you didn't know until you ate peanuts. Usually back then, you'd die from it, and not have kids. Nowadays, people have peanut allergies, th... |
Why do Freemasons honor Egyptian Gods like "Osiris", "Isis", and "Ra"? | Some say the origins of the free masons go back to secret society in pagan cultures, ancient Egypt and Greece. Here's a link sorry I'm on my phone _URL_0_ |
How can companies like Pearson completely dominate the educational market, and seemingly standardize what all students across the country "need" to learn? | To build on what u/TedwinV said, it's also pretty expensive to develop a textbook. But because of economies of scale, big publishers can offer those expensive books for a bit less than smaller publishers. |
Why do the vast majority of cars have their engine in the front? What benefits does this provide over mid or rear-engine vehicles? | In a frontal collision it's much better to have the engine at the front than behind the passengers. Putting the cargo area in the rear is allows more cargo to be carried without obstructing vision. Having more weight in the front of a car makes the car more stable and handle more predictably.having a 500 pound metal bl... |
Why does the water heater run out of hot water? | Water is heated in a tank to provide you hot water. It isn't capable of heating the water that hot as quickly as the water can flow, which is why there is a reservoir. A system capable of that level of heating would be ore expensive and challenging to implement. Everyone taking showers might brown out the electrical gr... |
Why do we keep houses warmer in the winter than in the summer? | Does anyone actually do this? I keep my AC at 76 and heat at 65. I can't even imagine the bills that would come from cranking the heat up to 76 or more. |
How were wine tastings started and why are you required to spit the wine out afterwards instead of drinking it? | You don't have to spit it out. I never did. But, I did embarrass myself at or after several wine tastings.You can generally get a wine tasting started by calling a vineyard and asking "Hey, when is your next wine tasting and how do I get signed up?" And they ask you to spit it out because they don't want you getting dr... |
How does the brain have a pre-built language function, when language was invented by humans? Did this part of the brain evolve over time? | It's not so much a pre-built language function as it is the capacity to acquire a language. While our language as it is is a human construction, communication isn't; it's a natural system of behaviour and our brains can learn that. |
Tax returns are the return of excess wages that the government in a sense loaned from us. Why aren't we entitled to interest on the excess tax? | A tax return is the form you fill out declaring your income and deductions. A tax refund is what you're talking about. And we're not entitled to it because there's no provision in the law for it. If you find that you are often overpaying the tax, and this bothers you, you should look to adjust your withholding. Some pe... |
Why does sound need a medium to exist? | You're right, they are vibrations that we perceive! The issue here is that sound is, in fact, vibration. For sound to propagate, the vibration needs to propagate as well, and for the vibration to propagate you need a medium in which it can do so. You can't have empty space vibrate, because vibration needs MATTER to exi... |
What happens when everyone when everyone starts using adblock | Websites will start blocking content if Adblock is detected. Hulu already does this. I am astounded others haven't done the same. Give it time, and once a high enough percentage of internet users have Adblock, companies will start developing defenses. |
Why is it when we are at school the majority of tests are memory based when in the real world we can look formulas and definitions up? | You went to a bad school, or at least had bad teachers? I had plenty of those myself, but also had some great teachers with classes in which everything up to and including my final exams were entirely open-book. Just about anything short of the internet. I'm not saying they were easy, I'm saying some teachers do teach ... |
When the United States places sanctions on certain Russian citizens, who are they? Why these people, and why not Putin? | These are mostly people who are friends of Putin or other important people in the Russian Government. Obama is trying to use sanctions against wealthy Russians and others who do business in or visit the West in order to try to get Putin to cave on Ukraine. Most of Putin's affairs probably all occur only within Russia s... |
What stops humans from sleeping for days at a time? | My best guess as to why we don't sleep for longer periods of time is due to light. Your body has an internal clock, known as a [circadian rhythm], which is kept on track by certain external clues such as daylight. Even some people who are blind are still able to have their internal clock set straight by light even thou... |
How did coating a weapon like a dagger in poison work? wouldn't the poison fall off if the weapon is too fast, like an arrow? | Typically I believe weapons that were coated in actual venom or poison were allowed to air dry. However its a lot easier and cheaper to smear shit on your arrows and that bacteria is obviously bad news if it finds a new home in an open wound Edit: apparently obligatory *I'm not a fucking expert and most of my knowledge... |
What's so special about Ecuador/Iceland regarding political asylum? Can't the US govt. pressure them like any other country? | The US could try to pressure them, but Iceland is a very isolated and self sufficient country that isn't terribly involved in international affairs. There is not much the US could do to pressure it. Ecuador has been scoring political street cred with its neighbors by being critical of the US without going all Hugo Chav... |
How do animals survive the night from nocturnal predators while they sleep? It seems hard enough to survive their waking hours. | There's almost as many different methods as there are creatures! Sloths, for example, sleep at the end of small branches so their heavy predators can't get to them. Lizards are very skinny and can tuck themselves under rocks that birds or other predators couldn't get to. Many animals like to burrow underground to hide.... |
Why Windows 64bit is x64 but 32bit is also known as x84 and not x32? | Its a 'name/label', it doesn't actually say what's in it.

The real problem i... |
Why are DJ's treated like artists, with a stage name and everything, and their own 'shows' people get tickets to, when they just play other people's copyrighted music? | What Pesto says is right, but there's also a lot more to any DJ worth their salt. Any numbnut with a preamp soundboard and some speakers can cue up a playlist and press spacebar. Any Joe with DJware or a multichannel board can crossfade to a new track as a previous one ends.

why no one has created a commercial diet that includes a balanced amount of all required nutrients for humans. | There is.[ It's called Soylent] and is an all in one drink that claims to be able to offer your body with everything it needs to survive. It comes around $3 a meal and while I can't say I'd really like the idea of not eating anything but that liquid for all my meals It might be what you're looking for.Pretty sure that ... |
