Title ll of net neutrality. How could ISP's benefit from having control of internet speed on certain websites and apps?
|
They would get the power to censor as they see fit and they would get the opportunity to add extra fees - an example would be to limit data speeds to the point where streaming becomes impossible, and then they'd charge you extra to raise the limit so you can watch Netflix, or have Netflix pay them extra not to do that so their customers can access their service.

Why do we get the feeling that someone is watching us?
|
Couple of things. First our brain isn't 1 thing. It is multitude of processes that works together. Sometimes brain gets confused resulting in your having "supernatural" experiences. One of the minor being feeling of being watched. If your brain can't rationalize your senses, you get those feelings.I'm not exactly the most qualified to answer this but I suspect it's part of an evolutionary trait. From an evolutionary standpoint it's likely better to be suspicious of the environment around you than to assume safety even if 99% of the time it's a false sense of suspicion.

Why and how does physical pain manifest when one is sleep deprived?
|
The pain in this case is motivating the organism to find a quiet, closed space to sleep. When sleep deprived, global bodily inflammation rates are higher due to overburdening of the stress system and the protective immune responses. The brain, cardiovascular and the immune system are some the main biological processes that undergo repair at night. From an evolutionary perspective, these systems developed so that they are downregulated during the day when foraging and hunting. At night these pursuits are difficult or dangerous so the body switches investing energy into maintenance, growth and repair at night when they aren't in use. By not sleeping, the biological functions are overclocked. In the brain for example, neural substrates of glucose and ATP must be replenished, the toxins removed, and the pathway connections reorganized. This leads to headaches, impaired cognitive functions, slowed reaction times etc. Imagine playing a soccer game for 4 hours as opposed to the usual 90 minutes. Performance will decline in the later portions of the game. The body needs a certain amount of sleep every day and homeostatic mechanisms will come into play whereby the next sleep session will be longer duration or better quality.

what actually goes on in clown school. All I know is it's hard to get into, but what is the benefit, and what do the clowns learn?
|
Circus clowns perform a variety of functions, including comedy, filler between major acts, incorporating and communicating with the audience, slapstick routines, stunts, improv, prop comedy, etc. It's like a mixture of improv school and circus school.I wonder if in Clown School when the teacher catches you just quietly sitting there doing nothing if he yells at you *Hey! Knock it off and start clowning around!*', "That's it. You people have stood in my way long enough. In going to clown college! I don't think any of us expected him to say that!

Why can children sleep through being lifted out of a car and carried inside, whereas I would wake up immediately if someone lifted me out of bed?

The science behind a tandoori oven
|
the structure is basically a chimney. the heat from the coals creates an upward draft which adds more air and basically makes the coal burn even hotter. the heat is concentrated in the small space and insulated by the vermiculite so it doesn't escape sideways but only upwards.

What will result from the 'Farm Bill' Obama signed?
|
I don't claim to be an expert on the issue. The below is taken directly from an article in the current issue of The Economist. After a delay of two years the Senate passed the farm bill, a strange piece of legislation which costs nearly a trillion dollars. It mixes benefits that mostly go to the poor with agricultural subsidies that mostly go to the rich .The bill passed with some pretend reforms to the food-stamps program; Democrats complained about savage cuts to food stamps, which actually amounted to a mere 1% over ten years compared with an earlier version. And the big picture is that food-stamp spending has exploded since 2000.Food stamps have high administrative costs and are open to corruption: some beneficiaries buy big packs of fizzy drinks and sell them back to the store for cash, minus the middleman’s cut. The federal government runs a confusing mess of 126 anti-poverty programs, many of which overlap, but there is no serious talk of making the system simpler and more effective. The new law also shifts towards an insurance model, where farmers get paid if crops fail or prices fall too far. This sounds reasonable, but the insurance schemes lock in high prices when farming is profitable. The part of the farm bill that actually deals with farming is even worse. Farmers are not the only people whose businesses have ups and downs; there is no reason why they should get special treatment, considering crop insurance is largely underwritten by taxpayers. These subsidies distort behavior and trade in unhelpful ways. They have created products that make no economic sense in the rest of the world, such as making sugar from corn. As a penalty for keeping cotton subsidies in place, the World Trade Organization's rules require the American government to pay $147m a year to compensate farmers in Brazil. Obviously this is taken from a non-government interference point of view so take it as you may

Why does the Madeleine's case had and still has so much attention from the media and Scotland Yard?
|
I assume you are talking about Madeleine McCann? It still gets coverage because for one, it's still an open case. New suspects were entered into the case after Madeleine was reported to have been seen abroad over the last few years. There is no conclusive evidence that she's dead. Also, it was a very interesting case. The public turned against the parents, because of what they were. Middle-class, relatively successful people. News sources were convinced that the couple were involved in the disappearance themselves. Those that didn't think that, still blamed the parents for bad parenting. This was also a time when social media started to be more involved. Twitter was still in its infancy, and was a way for all these rumors to spread around easily. Tldr: IMO it wasn't really about McCann, but the accusations towards her parents that made it an interesting case.

How come I can't downvote comments in some subreddits?
|
In a subreddit, the admins can change what it looks like. Some subreddits want to promote a positive environment by getting rid of the down arrow. However, this doesn't mean the ability to use it is gone. If you do some fancy computer stuff you can still use it. .Uncheck the check mark in "Use Subreddit Style" on the upper left side and you will be able to.

How does a Nuclear Submarine operate for decades using nuclear material that is the size of a human fist according to the Captain of a Nuclear Submarine?
|
That's the amazing thing about nuclear power; energy density. You can extract tremendous energy from a very small amount of material because you are literally converting mass to energy. Unlike most forms of power generation that just rearrange atoms, nuclear power rips them apart and uses the resulting energy to do work. A submarine can go for about three decades without needing to refuel.Nuclear fuel is *incredibly* energy dense; [this xkcd] does a nice job of summarizing the point. Nuclear reactors operate at a relatively slow rate; at any given time, they are only harvesting a tiny fraction of the available energy within the nuclear fuel.

What is a memristor?
|
A memristor is a piece of an electrical circuit that remembers how much current has passed through it, and in which direction . In the future, we might be able to use memristors to make switches and memory for computers that are better than the kinds of switches and memory that we have at the moment . There are teams of people at universities and companies trying to find ways to build memristors cheaply and turn them into useful stuff, but they haven't been commercialised yet. One way things might be different with memristors is that computer hard drives and RAM might merge into one device that is fast like RAM but cheap and persistent like a hard drive.

does temperature effect how long a smell lingers? If so what causes it to linger in the cold/heat longer than the opposite?
|
Yes. Temperature has an effect on the existence and motion of smells, the warmer the temperature, the more "active" smell molecules are . This means that smelly things are smellier when they are warmer. As for lingering, that is impacted more by the conditions than by the temperature. Although the warmer gas will become more diffuse, which should lead to the smell being less strong, it will also allow the source to produce more gas molecules, which will strengthen the smell. From personal experience, having temperatures below freezing drastically reduces the amount and duration of any odours. The most interesting thing about spring is having smells return as the snow melts .

Why do apples turn brown so quickly where the inside is exposed?
|
When an apple is cut , oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products. Lemon juice helps keep the apple from browning, because it is full of ascorbic acid and it has a low pH level. Ascorbic acid works because oxygen will react with it before it will react with the polyphenol oxidase. So spray your apple with lemon juice if browning is an issue for you.To put it really simply, it rusts. It's not *really* rust, but there are certain iron-containing chemicals in the apple which connect with oxygen in the air once they are exposed, creating an oxide.

Can black holes close off and stop being what we know of as black holes?
|
They can in fact! It's due to a cool thing called Hawking Radiation which black holes emit. It's the only thing they give off, meaning they aren't totally black. Right so what happens at a super sub atomic level, like really fucking tiny there are two little things of which I forgot the name. Lets call them thing one and thing two [] Look at those two buddies. Now they appear out of nothing and then attract to one another and then pop out of existence. They have to go because the universe isn't a fan of free things happening. Now what happens to a blackhole is on the very edge. Thing 1 and Thing 2 appear but Thing 2 is sucked into the black hole! OH NO! Thing 1 is left on it's own and the universe is pissed about that. This thing has appear and is staying in the universe and the price must be paid for thing 2. The only thing that can pay this debt is the blackhole which shrinks in payment. It's teenie tiny, ridiculously tiny amount that comes off the black hole. However over time it takes it's toll, and for small black holes it can make them 'evaporate' away.

Why do Republicans only require 1,237 delegates for a nomination while Democrats require 2,383?
|
Because there are 2,475 delegates at the GOP convention and 4,766 at the Democratic convention. The number of delegates really isn't important -- what's important is the percentage of the total delegates they get, because both parties require a majority of the delegates to become a nominee.Each party makes its own set of rules for picking the party's candidate, so there's no reason why the Democrats and Republicans would have identical systems. The Democrats assign more delegates to certain states and they have more unpledged delegates , so more delegates come to their convention. With more delegates voting, the more votes are needed to reach a majorityPolitical parties are considered private organizations and get to set their own rules for how they nominate their candidate for president. The Democrats have decided that more candidates is important while the Republicans have decided that fewer works well enough for them.

What exactly does "dying of natural causes" mean?
|
Its just a saying really. "Old Age" is not the killer, Pneumonia or heart failure is usually what does the guy in. However, as we get older our bodies get less and less able to fight off things like that. Our hearts get weaker, our bodies get less efficient and so on. So really "dying of old age" is a polite way of saying "their body fell to shit and something offed them. But don't feel bad, they were really old so it was normal."Everything has a "life". Some things have a "shelf life". Some things have a "half life". Think of your body like the energizer bunny. **NO BATTERY LASTS LONGER**, but even that battery will stop going, right? The bunny will bang the drums furiously, and then a little slower, and then a little slower. As it dies it will do a comical slow motion beat accompanied by the slow unwinding sound of the gears going still. Your body will not stop like an automaton, but think of your heart like a battery; it, too, will slow down one day, and stop. Right now you are five, and you can beat the drums *furiously*. I am five and thirty, and my arms have slowed. Your grandpa moves slower still, and one day, all our battery will die, and our gears will stop, and we, too, will die. **TL;DR:** Natural causes is the energizer bunny; now go outside and playOrgan failure. But when someone is old enough that death is expected, it's a combination of things failing. There's no real reason to dig in and find out which organ ultimately caused death, better to move on and just say "natural causes".You didn't get murdered or die in some sort of accident.

What did old movies mean when they said "[this movie] has been formatted to fit this screen."
|
Movie screens where always wider than the normal home television. They have to alter the film in order to correctly fit your television screen. "Full Screen" versions of movies have black bars at the top and bottom of the screen. What many people don't realize is that the black bars aren't covering anything because there wasn't anything there to begin with. Because the original screen format was designed for movie theaters so nothing ever existed there to begin with. Next time you go to the movies, take a look at the size and shape of the theater screen. With most theaters, the screen is significantly wider than it is tall. Then take a look at your television. If you notice that while it is also rectangular, it is nowhere near as wide as the theater screen is . not everything is visible in the fullscreen version of the movie compared to the original format. By expanding the image to fill the screen, unfortunately the sides of the image are cut off. On average, about 30% of the picture is cut off on the sides, especially on movies filmed in 2.35:1 format. Movies like Star Wars and Mad Max are filmed in 2.35:1 format. Most people never realized or even noticed the loss of the movies footage. The reason you don't see this warning anymore is because most of all modern televisions are now widescreen. They can support the original format the movie was filmed in. Almost all movies are filmed to fit modern televisions now.

Why do I have to worry about how much data I'm using on my phone but not on my desktop? And why can't I get the same deal for my phone?
|
Your phone's data is coming from an expensive cellular network. Your desktop or laptop is using your inexpensive home network, probably DSL or cable. You can't get the same deal for both because they are two different delivery systems. I don't know what a good analogy is -- maybe restaurant prices vs room service prices? You pay much more to have some guy wheel your food to your hotel room and you also pay much more for cellular data. edited to add: connect your phone to your home network when you're at home so you can use your home wireless instead of the cellular network, and go nuts downloading whatever you want at the much cheaper rate.

Why do eyes have color?
|
Our skin, hair, and eye colour are determined by melanin levels. Melanin is pigment that is also responsible for tanning. For example, lighter-skinned people have less melanin than darker-skinned people. People with Albinism, however, have no melanin/pigment. Freckles are an example of concentrated melanin in one's skin. So:Red Eyes, as seen in people with Albinism, are produced when there is *no* melanin. From least to greatest melanin levels, the eye colours are as follows: Blue, Green, Hazel, and Brown. Brown eyes contain the most melanin, and blue eyes contain the least.eye color depends on how much pigment you have. same as hair and skin color.

With Snowden revealing all of this compromising information why does it seem as if nothing really is being done about it? And if something was, who would be to blame?
|
Because no matter how much we hate the NSA spying on us, it doesn't affect our lives in any meaningful way. I have food on my table, a roof over my head and a pay check Until most or all these things are taken from me, my life isn't affected", 'Because Americans are to comfortable and lazy to stand up and fuckin start the revolution that they needPartially because mainstream media isn't covering it like they should. Their stories are "omg! This guy is a traitor, must be caught!" While they should be "omg! Look what our government is doing to us!"', "The truth is that quite a lot has changed and much is going on. Every conversation in congress is now informed by the Snowden leaks. And the House [voted to defund a program exposed by Snowden] just a few weeks ago. A bunch of legal filings, armed with Snowden evidence, are slowly making their way through courts now, and judges are not pleased by what they see. These court cases, further analysis of Snowden files and later leaks may add up to criminal punishments. But we are talking about years. This problem was years in the making, it's going to take years to unravel.

How come you never see any jacked golf players?
|
No, the opposite. Hitting the ball far comes from flexibility and technique. Basically the longer your back swing, the faster your head speed, and assuming you contact the ball square, that will result in wicked length. If you're all jacked with muscle, you can't rotate enough to get the needed speed.

Why does buying stuff (non-essential) make us happy?
|
It depends on what kind of stuff you're buying, but essentially, it's because products are advertised as lifestyle components rather than things. E.G. You're not buying a Mercedes Benz, you're prestigious and the envy of others. You're not buying Prada sunglasses, you're chic and classy. You're not buying TOMS shoes, you're saving the world. Of course, this is a pretty empty, fleeting happiness. Partly because manufacturers need to keep selling stuff, and advertise how much better their latest and greatest products are . But also because of ingrained human nature--if we were permanently happy from any one thing or things, we would have stagnated as a species. Relevant LifeHack--*If* you're going to spend money pursuing happiness, spend on experiences, not things: _URL_0_", 'Because advertising works! I note that it doesn't make everyone happy.. it makes me quite sad to see people buying non-essential junk as I know it is hurting the planet. However other people seem to find meaning in owning "stuff" they think that having whatever they "want" as opposed to need items only makes them more complete. They have been told that "The American Dream" is having everything you could ever want and nobody was told that having junk is killing the planet. It's gotten so bad that people find comfort in collecting things or hoarding them.. for some reason people find value in this. People have been told that if they see something they want it doesn't matter if they need it or not.. they "deserve" to have it.. so people are brainwashed into thinking that stuff = happiness. Basically people are told to buy junk to be happy because it means they have to work more so they can afford all the stuff.. more people working = more people paying taxes. A win for the government, a loss for the planet and a loss for common sense.I'd guess because we are hardwired to be hunter/gatherers and acquiring things triggers our mental reward system.

Why do predictive text/autocorrect seem hell-bent on using typos you made one time a month ago?
|
If it doesn't catch the typo, or if you make the same typo multiple times, it will add a new word to your phones dictionary . Most phones will let you access the dictionary of new words that have been added, so you can go in, find the typo, and delete it, so it won't auto correct to the typo anymore.

Do fat people keep eating because they are still hungry, or do they eat past their natural hunger-level?
|
As a physician's perspective, it is because they are still hungry. When you continue eating past your natural hunger level, stomach adapts to the change by increasing its size, thus capable of eating more food, = more calories. this cycle goes on until the eating capacity is so big that they get easily hungry.

People say prostitution is "recession-proof." How is this true?
|
I was living in Las Vegas, working in a casino during the 2007 crash and subsequent recession years. Prostitution is not recession proof. I worked the night shift and saw plenty of hookers getting desperate for business over that three year period. Dropping prices, dropping standards, and worst of all, dropping safety standards to get some work. It was so depressing watching women who found themselves looking a bit worse for wear in their early thirties try all kinds of hustling to get by because their old regulars went broke in the mortgage crisis and didn't call anymore."Vice" spending in general is somewhat recession proof. Things like alcohol, drugs, gambling, and prostitutes provide a service that's escapist in nature. So people who want to take their mind of the everyday might invest in one or more of the "vice" spending actions. It's recession proof because people who lose their livelihood are quite likely to turn to one of the "vices". You might not afford that holiday to the Caribbeans , but you can afford a bottle of whiskey and a prostitute.The common wisdom is that when people hit hard times, they often indulge in their vices. Losing a house or a car can paradoxically free up money, and when things get bad, discouraged people often don't worry about them getting worry, and need some kind of amusement to distract themselves form the troubles.

Why is it that a high-calore meal doesn't keep me satisfied any longer than a low-calorie meal?
|
Generally what you eat has little impact on the amount of sugars in your blood, otherwise you would be in hyperglycemic state after every meal. Hunger and satiety are just feelings that are connected to certain hormones in your body, when you eat you are starting to produce leptin, high enough level of leptin in your body will stop you from feeling hunger, raising leptin levels to sufficient amount will take around 15 minutes from the start of a meal. After some time levels of leptin will fall and you will feel hungry again. Levels of leptin are not connected to how much nutrients are in the food because some time has to pass to get them into your bloodstream. As far as I understand you can eat paper and feel full for the same time as you would by eating the same amount of sugar. The whole topic is quite hard to easly explain - do you want me to elaborate on anything? Edit: low levels of leptin will make your body produce ghrelin which makes you fill hunger, not just absence of leptin.

why are cell phone bills so expensive? What are we actually paying for?
|
You're paying what the market will bear. That's basically the answer. Sometimes people complain about the markup on cell service , but this kind of thinking forgets the service provider has very, very large capital expenses above and beyond the marginal expense of transmitting one of your texts, and the complainer obviously finds $10 to be worth it, since they're currently agreeing to pay it every month.

Why are treats so effective with dogs? Aren't they made of the same ingredients as regular food?

You can use anything as a treat, even his regular food. It's not the food that's important to your dog, it's that it's a reward. I knew of a dog trainer who use cheese squares, to train this giant Russian whatever the fuck/tiny horse of a dog. He'd get 100 bits out of one slice.

What is a limit in calculus?
|
I am not sure what you mean by "exactly", but there are many ways to thing of a limit, some are more mathematically rigorous than others, some are more general than others. If you think of the graph of nice function or / ) then take out one point leaving a hole then the y-value of that hole is a limit of the function as you approach the x-value of the removed point. . A more general idea of a limit is a "limit point", it is not different than the previous notion, the idea is just a little more general . Imagine you have a set of points , then a limit point for that set is a point with the property that if try to "draw a circle" around the point, that no matter how hard you try, or how small you draw your circle, that the circle you draw around your point will always include other points from the original set. think about that with the graph with a single point removed no matter how small a circle you draw around the removed point, that little circle will always hit the graph in other points Another example, think of the open interval on the real line and try to draw a small interval around either end point a small interval around the end points will always hit the interval so both 0 and 1 are limit points of the open interval . Keep in mind, limit points can also be part of the set, they do not have to be outside the set, in the interval the point 1/2 is also a limit point because any interval around 1/2 also contains *other points besides the 1/2*. That is just the basic idea of limits. In calculus the limits of a function are typically defined using the Delta-Epsilon definition it defines the same objects but using equations instead of words.

How does salt water from the sea turn into fresh water like in rivers and so on?
|
When seawater evaporates, the salt does not evaporate with it. Hence, the rain is freshwater.Salt is not air soluble, water is. When water evaporates, it becomes humidity in air. When air is warm, the molecules are spaced farther apart, leaving space for water molecules to float amongst the air. This leaves the salt in the water that has not gasified. Hand on, never mind, I'm not good at this eli5 thing ", 'Do they not cover the water cycle in school anymore? To put it simply, water evaporates to form water vapor, which condenses in the atmosphere and eventually falls back as rain. When salt water evaporates, it leaves the salt behind.

what determines hangover severity?
|
Easy answer is hydration level. You could have drank more water before or after. Food intake before drinking comes in. Sugar content of your drinks.Some of the other ingredients in alcoholic beverages contribute. Whiskey is 40% alcohol, the other 60% is? You want an easier hangover, drink vodka, vodka is just alcohol and water. Then drink lots of water before bed. Then snort some oxycontin when you wake up. You'll be right as rain.

Why is it called music 'theory?' Is there actually anything theoretical about it?
|
Theory != guess. Think of theory in it's scientific terms, where it means something more akin to "describing how/why things work they way they do"', "Music theory is the study of the structure of music. For example, if you listen to pop songs from the past 5 years, you'll notice that a lot of them sound similar. This is because they all use similar progressions and note choices that are known to work. There are many alternate music theories that probably don't sound familiar to you. One of these is microtonal music. This refers to music that is made up of scales that don't use the traditional 12 notes that we know. They often go up to having 40 or more notes in an octave. Modern Western music theory was developed a long time ago in ancient Europe, when the modern idea of notes didn't exist yet, and musicians had to actually invent notes to write music. They generally used instruments similar to harps. They would have an individual bridge for each string, and these bridges could be moved to tune each note to a different frequency. If you listen to Classical European music vs. Classical Eastern Asian music, you'll notice that they sound a LOT different . This can help to show you how notes shouldn't be taken for granted, and that it actually took a lot of scientific know-how to develop the system of notes we use today. Basically, music theory is a very complicated scientific study of how to organize sounds in ways that sound good .

Why can I see IR light on my phone camera, but not with my eyes?

The phone camera's sensor can detect IR light, but your eyes cannot. The phone sensor reports everything it picks up as visible light though, so your display shifts the IR into the range visible to humans for display.

From a very young age, I've only been able to see out of one eye. What is depth perception?
|
Depth perception is a much more complex and interesting concept than I expected, so thanks for asking. It's essentially the idea of seeing the world in 3-D and understanding how far away things are. There are two different types of visual cues for depth. Monocular, which means you can recognize them with one eye, and binocular, which require two eyes. Monocular cues include motion parallax, depth from motion perspective familiar size There are a whole bunch more, which you can read about here: _URL_0_ While most depth perception cues are monocular, some require two eyes. These include stereopsis, and convergence Can you gain the skill? You already have most of it, but you won't gain the binocular part. But there is a trick you can use to see what it's like. If you take pictures of the night sky from two different places on earth at the same time, and put them together, it'll look sorta 3D. That is because the two cameras are like two eyes with a slight distance between them. This trick is sometimes used by astronomers to estimate the distance of stars. You can read about it here, and check out some gifs that might help simulate depth perception with two eyes for you: _URL_1_ Overall, binocular depth perception is overrated. Sure having both eyes would be better, but most of our visual cues are monocular, so you aren't missing out on too much. The former captain of India's cricket team, Mansoor Ali Khan Pataudi, was blind in one eye. This is especially impressive because cricket relies on depth perception probably more than any sport except shooting, and he was considered one of the best players of all time.

I've read over and over again that adults cats only meow at humans, so why do my cats meow at eachother when they are playing?
|
The Internet is wrong about this cat fact. Cats meow and make other vocalizations at each other when humans are not present. The Internet is also wrong that wild cat species do not meow and wild wolves do not bark. Kittens and pups of these species do make these noises often, but not so often as adults. In the process of domestication, we have extended this and other childhood behaviors into adulthood.IIRC, it's not that they don't meow at humans. It's that only domestic cats meow, because they evolved it to communicate with humans. Cats in the wild only purr or roar.

Why do banks get to charge 20% for credit cards and I only get 0.01% for a savings account?
|
how exactly is that unfair? it is *their* services that *they* are providing for *their* price. they are allowed to do it because they are a business and are allowed to make profit and charge their customers for their servicesInterest rates on loans are in large part a measure of the risk involved -- part of the point of an interest rate is to convince you to give someone your money when there's a risk you may not get it back. Your savings account is guaranteed. There is essentially no chance you will lose the money *even if the bank goes bankrupt*, because it is insured by the US government. In contrast, there's a decent chance a bank will lose money from a credit card loan. You are more likely to go bankrupt than the United States government, and so loans to you are more risky than loans to a bank. Even worse for the bank, if you go bankrupt they just lose the money they lent you for the credit card . That doesn't explain all the disparity; some of it is due to the fact that people are willing to accept those rates, and banks need to make money . But even in the absence of "customers are willing to pay it," one would expect credit card rates to be much higher than savings accouint rates.The credit card that I use has a much lower interest rate. Part of the interest rate is to cover losses from people who default. If you're a good risk, you might be offered a better rate.

How was it decided that Leap Year was necessary?
|
The earth circles the sun in 365 days and six hours. The extra time could be calculated by using star positions relative to the earth, or by tracking the earth's position over time. Because the extra six hours was annoying, it was stashed until enough six hour units were stored to add another day.While others are answering the direct question, I feel obliged to point out that the Julian calendar has leap years. Thus the idea of leap years is much older than the Gregorian, and the question needs to be answered based on that older technology. What the Gregorian calendar introduced are the 100 year and 400 hundred year rules. Thus 1900 was a leap year in the Julian but not the Gregorian, while 2000 was a leap year in both.

How do firefighters discover the cause of the fire?
|
Through having fought a lot of fires themselves, often. Dogs and sniffer machines that can detect an accelerant are frequently used. Fire char from where it began helps them locate the starting point. Also, police type interviews of witnesses and looking at the history of a building all are things they look for as well as many more. Source , 27 years as an urban firefighter who liked to know just how in the he** the damned thing got started.

Why is the perspective in Russian animation so different from Westernized animation?

This style is paper cut out animation. The characters are cut out of paper and laid flat on sheets for each frame of animation. Generally, Disney or HB painted the characters on clear celluloid laid flat over a glass or card background. _URL_0_

Why do so many people lack the discipline to follow through with things like new years resolutions?
|
Usually resolutions are very vague, or general. "I'm going to lose 50 lbs this year!" isn't as concrete as "I'm going to walk a mile every day". Those who make the latter resolutions probably stick with them more often.If it's something you actually care about, then it's not something you typically wait a whole year to start. New Years resolutions tend to be vague, well meaning ideas, not actual plans to change things. Besides, it's practically tradition to make a resolution you're never *actually* planning on doing. Going in with the underlying assumption that the resolution idea is silly to start with doesn't help either.

Why is brown bread considered healthier than white bread? Is it healthier?

White bread is heavily processed, and isn't very good for you. Brown bread varies, some are essentially dyed white bread but the kind with all the seeds in it are very good for you.

why aren't anti vaccine parents held liable when they cause outbreaks of preventable desieses?
|
One of the first obstacles to overcome would be proving that the outbreak wouldn't have happened at all had it not been for the negligence of these parents. Because the infection could have started with or spread through vaccinated kids, its impossible to prove beyond a reasonable doubt. Furthermore, holding people liable for spreading sickness is a very dangerous precedent to set. Imagine if you could be sued for giving a coworker a serious flu.

how does Apple get away with their proprietary charging plugs and ornery connections?
|
Apple introduced Thunderbolt connectors on its computers because, like Firewire before it, Thunderbolt promises to enable some incredibly fast transfer rates between the computer and external hard drives. Thunderbolt also incorporates the Displayport standard, so one connector can move around data at a seriously high speed *and* send lots of data to a compatible computer monitor. The folks who do jobs that need to be able to manipulate large quantities of data, such as video editing, will happily pay for all the bandwidth Apple can give them. As for the Lightning connector on iOS devices, the connector provides about 8 pins vs. USB's 4 pins. Those 8 pins can be reconfigured on the fly, so that licensed third-party accessories can use those 8 pins for audio, video, whatever . The other end of the cable is USB, of course, which I believe satisfies the European Union's requirement that cell phones be capable of charging via USB without the need for proprietery chargers. It will perhaps someday become USB3 when Apple decides that the extra bandwidth is necessary .

Why do many men enjoy watching porn where the male actors have gigantic penises? (NSFW)
|
Because I can relate to them. It helps if they are handsome and athletic too. Most porns are to my liking because of this.Well, without going into too much weirdness, there's a few practical reasons that this works: a larger organ means more motion is possible, which films well. It also allows for more versatility. Also, it takes up more screen space. I think most of the reasons are practical and have to do with filming.

How are photons their own antiparticle? (Without they annihilating other photons or self-annihilating)
|
A photon is has no charge which is why you could consider a photon its own antiparticle. They can annihilate each other and create an electron-positron-pair, or even more massive particle pairs if energetic enough . Usually photons just go past each other and do not collide as their electromagnetic fields simply overlap and sum up without any interaction.

If we need UV-blocking sunglasses/sunblock to protect ourselves from the sun, why wouldn't leaving a clear bottle of water in the sun sterilize the water?
|
It does. The SODIS method is a way to use clear 2-liter bottles and sunlight to make water safe to drink, very useful in third world countriesour skin cells are damaged by UV. mold on the other hand thrives on light in the presence of water. as do alot of other algae. blue and green algae spores are EVERYWHEREBecause what slightly damages our skin/eyes may not destroy harmful bacteria. However, it *is* better than nothing to irradiate a bottle of water if you have nothing else.

Why won't the US fight a War on Mental Illness a la drugs/poverty when such an effort is sorely needed?

Why do companies 'throw away' good food as opposed to give it away for free?
|
If people knew they could get food for free simply by waiting, not a lot of people would pay for food.My brother used to be the night manager at a pizza place. At the end of the shift, there were always a few mistake pizzas left over, and if none of the employees wanted them, he'd give them away. However, word got around, and there would always be kids hanging out at the end of the shift trying to score free pizzas. Not only was it a hassle, many of were doing that *instead* of paying for a pizza, so he was losing potential customers. He even suspected some were calling in bogus orders so there would be more mistake pizzas available. Most importantly, none of them were going to go hungry if they didn't get a pizza. So he started throwing them away. His profits went up, and he didn't have to deal with slacker kids whining for free stuff.

Finnish Education System Success?
|
* Homogeneous society. This is actually pretty important. Having students from many different backgrounds makes it tricky to teach effectively. By homogeneous, I mean white, middle class , and Lutheran. * Extremely-well trained teachers. Teachers in Finland are cream of the crop. It's almost unheard of for someone to be able to teach without at least a Masters Degree. There are a bunch of specialized programs that teachers have to got through, teaching them the things ranging from developmental psychology to effective teaching methods. * Highly valued teachers. It's an unfortunate fact that teachers aren't given the credit that they deserve in many countries. It's a hard job. It's also pretty damn important. Like, shit, you're shaping the minds of the future leaders of the country. Teachers in Finland are respected, treated right, and fairly compensated. This itself is a self-fulfilling sort of thing, since teachers being respected and treated well leads to more people wanting to become teachers. This of course leads to a more competitive field, in which only the best actually get to become teachers. The cycle continues.

What's the difference between dopamine and serotonin? Is there a difference?

Short answer, yes, they are different but they have many similar functions. While both are neurotransmitters , dopamine is more involved in movements and thinking, while serotonin is more involved in emotions.

Why are gems valuable?
|
They're pretty, rare, and associated with wealth and status. Some gems have unique properties which have industrial uses, such as diamond's hardness, or ruby's staying-the-same-shapeness, but mostly it's just "ooh, shiny"The worth of an item is due to supply and demand, for gemstones they are quite rare but a lot of people want them . This is what makes them valuable, if we found gems everywhere, they would be worth significantly less.It's a bit circular, people wants them because they are rare, they are rare because people want them.

What is a second mortgage and how does it work?
|
A second mortgage is basically a home equity loan. If you have a mortgage on your house, the home equity is the difference between the value of your house and what remains to be paid in the mortgage. For example, if you have a $100,000 house and you still owe $60,000 on it, the home equity is $40,000. That's the part that's already yours, if you will. A second mortgage is when you use all or part of that home equity to serve as collateral for a new loan.

Is it feasible to put a severely damaged/cut limb into a bucket to reserve blood instead of using a tourniquet to cut off blood flow?
|
No. Your heart never really pulls a suction on your circulatory system. Even the return path for low oxygen, high carbon dioxide blood is under a positive pressure relative to the atmosphere. Blood would go into the bucket from the arteries, but the veins wouldn't be sucking it back up.

What makes old people smell like old people?
|
Their cells are busy dying. Also, they do not bathe as often as you or I might, since it has become a much more difficult and risky proposition, since getting in and out of a tub or shower might literally mean the difference between life or death. A fall at their age can be fatal. Laundry is also a chore, so their clothing may not be washed as often or dry cleaned. Their homes may not be cleaned regularly. Nutrition may be poor. Medical needs may be unattended. Life itself is often very, very difficult from day to day. Things you and I take for granted are now a real chore. If you think about it, just survival may be on the line for them. Smelling good may be a luxury they just can't afford.

What do the values of the Dow, Nasdaq, and S & P actually mean?
|
The Dow, Nasdaq, and S & P all represent an aggregate of publicly traded companies. If you were to take the total amount of shares a company has, and multiply it by their share price, that is the current value of that company. Therefore, if you take a bunch of companies and aggregate their stock price, you can determine how much value they 've collectively gained and lost over a period of time. Since they are a representative sample of all businesses in the US, you can use these aggregate stock prices to objectively judge if the economy is "up" or "down".

Why can states allow minimum wages that are below the federal minimum wage level?
|
States with lower minimum wages like Arkansas $6.16, Georgia $5.15, Minnesota $5.15, and Wyoming $5.15 only apply to businesses that are not subject to the regulation of the FLSA. Generally, a business comes under the regulations of the FLSA if it has $500,000 or more in annual sales, or if the employees work in "interstate commerce." In this context, interstate commerce simply means business conducted between states. Other states have minimum wage standards that meet or exceed the FLSA regulations, However they are not compelled to force businesses that do not meet the above stated guidelines to pay federal minimum wage levels. The states mentioned above have for whatever reason decided that lower levels are acceptableThe minimum wage in Alabama is $7.25. States cannot have a lower minimum wage than the federal government allows. Technically Alabama does not even have a minumum wage, so they default to the federal one Many states do have laws however which allow certain positions, such as some tipped employees, to be paid less than minimum wage allows for these exceptions). _URL_0_', "They can't. Alabama may have set that minimum wage when the Fedral minimum was lower. Maybe they did it to spite Washington. Where a federal law and state law conflict, the Federal Law followed

What are Ayn Rand's books/beliefs about and why do people seem to either love or despise her?
|
Going to try to write this answer without being biased. The people that love her respect how outspoken she is about her capitalist beliefs, and how well she portrays it in her books. She is on the extreme end of Libertarianism, and there are better comments in other threads that explain what that is. The people that hate her tend to strongly disagree with her beliefs, and/or dislike how her novels seem to be purely based around those beliefs. They argue that without the ideals that she attempts to push, her books would have very little valueThere are a small but surprisingly obnoxious group of people who are 25 years old chronologically but 14 mentally, and who read her books and decide that her philosophy is a perfect excuse to be a super-selfish asshole who dicks over every other person in their life at every opportunity. These people love Rand because, well, they get off on being dicks. The rest of us who have to deal with these morans hate Rand not because we hate Ayn Rand herself, but because her followers are such incredible dicks to us and everyone else. Rand's philosophy is called Objectivism, and you can read the [Wikipedia page.] The friction usually comes when aforementioned moran dickheads think that being a total dickhead towards everyone in the world is in their "rational self-interest." Also, lassiez-faire capitalism almost always ends up becoming oligarchy - which is only in the rational self-interest of the few who are rich and powerful. All the rest of us get screwed when we live in an oligarchy.

Why do humans take so long to mature from infants into adults unlike other animals?
|
The human pregnancy is hugely flawed, we give birth after 9 months because that's the biggest the fetus can grow in order to be given birth to. Animals don't have this problem and so they give birth to young that can walk, feed themselves ect pretty much right from the moment they're born. So the human fetus is underdeveloped and has a lot more growing to do outside the womb.

Why do you watch TV and suddenly realize you have your mouth open.
|
When creating a movie or tv show the job of the director is to create a highly captivating end result, which if you are watching the show it probably is. One of my teachers called this the exit sign effect because when you are in a movie theatre you start watching and the exit signs are there and maybe bothering you, but when the movie starts going you forget about them. \r\rBasically what I'm saying is you are being captured by the content of the show and your muscles that require consciousness to be activated are relaxing because you aren't thinking about it. And if you relax your jaw muscles , your mouth opens. \r\rI hope i answered your question!

Where did the terms 'ho' and 'pimp' come from?
|
[\'Pimp\ is a late 16th century word, possibly deriving from the french word \'pimpant\' . Around 1785 in London, the word was first seen in text in the [Dictionary of the Vulgar Tongue] and meant "A male procurer, or cock bawd". In the 1970's, media attention coupled with a growing african-american subculture made terms like \'pimpmobile\' and \'pimp walk\' popular among their communities. [\'Ho\, on the other hand, is a much more recent term from the 1960's - the shorthand of \'whore\'. The etymology of the word [\'Whore\ stems from the Old English word \'hora\' meaning 'desire\'. TL;DR - the original pimps and hoes were English.

- Nobel Prize Economics 2012 (The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel)
|
We've had this thread a dozen times in the past week. Please search. My old post: > Roth, Shapley, David Gale, and a few other people figured out how to obtain efficient allocations of goods and services in markets where you aren't allowed to use prices. Examples of these are matching students to schools, matching spouses, and matching medical students to residency. The big contribution was an easy-to-implement algorithm to match people in those sorts of markets, using nothing more than each participant's preference ranking of the other side of the market. > The basic idea is this, and I'm sorry I can't ELI5 it further. You ask both sides of the market to rank the other side. Use students and schools as an example. So students make a ranking of schools from most desired to least desired, and schools make a ranking of prospective students from most desired to least desired. Then you have each student apply to their favorite school. Schools decide to accept or reject students. The rejected students then apply to their second-best school. Schools again accept or reject, and at this stage they can reject previously-accepted people if better applicants come along. The process continues until all students are matched. You can prove that this match is optimal: there is no pair where the student would rather be at that school than where they ended up, and the school would rather have that student than another one they picked. Note that the actual process of apply- > provisionally accept- > re-apply can all be done on a computer, and the output will be the final matching of students to schools.

Why do people get gold fronts/grills?
|
there is a culture of flashiness and bravado in alot of poor urban areas. you could say that its a way of "proving" your identity as a gangsta, baller, what-have-you, because gansta and baller attitudes are what is accepted in these cultures. It displays wealth and status, like eperman said, and serves as an intimidation factor somewhat. baring your teeth after all is an alpha-dog behavior, and ghetto culture almost demands an apha personality. I think they mostly look stupid, but every once in a while I'll see some huge dude with facial tattoos, rings covering his hands and gnarly dreads with a mouth full of gleaming, bejeweled chompers. Its probably the most intimidating "look" someone can pull off, if they can pull it off.

What is the difference between the US Senate and House of Representatives?
|
A Congressman in the House represents the interests of individual districts where you live. A Senator in the Senate represents the interests of the state at large. The reason we have two chambers is because the Framers were concerned with balancing out the power between the states. If we only had the House, then the large states would outnumber the small states and run everything. If we only had the Senate, then the large states would be deprived of a larger voice on issues that they would likely have to lead the way on. So, the Framers created a bicameral legislature to balance it out.In the Senate all states have an equal voice. So small states like Rhode Island are on equal footing with a state like New York. In the House there is a set amount of representatives that gets divided up based on state population. There are some responsibility differences but that is beyond explain like I'm 5. EDIT- On my phone and autocorrect hates me.

Why do doctors/etc. squirt out the contents of a syringe before administering it in movies/television?
|
Actually I do this daily. You need this when you are making a measured injection of some sort of medicine like insulin. Its not so much the air in the veins which could possibly be trouble, but instead to make sure the bubbles isnt messing up your measurement. I have a dog who needs exactly 4 ml of insulin a shot. Bubbles can cause it to move down .5 ml or more. So you put more into the syringe than you need then pull back. You then tap it until the air bubbles are on top. Then you squeeze out the air til it squirts. Then you put the extra insulin back in the container and can have a accurate measure. You dont need it if the drug is premeasured though like a vaccine doseThey are removing air from the syringe. You do not want a bubble of air in one of your veins or arteriesYou fill the needle up with more liquid than you need. There are air bubbles present in the needle, so you tap the needle to get the air bubbles to the top. You then squirt out the air and any liquid to get it exactly to the amount you want without there being any air presentIn fact, medical pros do "prime" the injection. But if you're talking about the syringe fountain that we tend to see on screen, that's a dramatized version of what actual practitioners doPointing the needle up and tapping it forces any air bubbles to the tip of the syringe, and squirting out some liquid removes the air. This is done to prevent clots.Long story short, it's to get excess air and air bubbles out of the syringe, as well as to make sure you have an accurate dose. You really, *really* shouldn't inject air into your bloodstream because enough of it can literally kill you by causing stuff like heart attacks and strokes. TV shows overdo it for dramatic effect, but it's something that medical professionals actually do.

Would a simultaneous double punch (both fists) deliver the same mechanical force as a single punch by the same person on average?
|
I'm no physicist but I would think the single punch would have more power, depending on how it was executed. A lot of the power behind a punch comes with being able to rotate your core at the same time as rapidly extending your arm. A double punch would negate this as all you would have is the force behind rapidly extending both arms at the same time without rotating the rest of your body.I agree that a straight on double punch would be less forceful, but what about swinging both arms like a baseball bat perhaps? That would allow the core, hips, and legs to be involved as well as more mass in motion towards the target.

All the rich and famous peoples lawyers just threatened websites with expensive legal action, they arent gone, they just arent explicitly displayed anywhereWhat makes you think they were effectively removed from the internet?They were removed from websites that cared, like Imgur.

Why is it that I enjoy listening to a song I like on the radio more than I like on my phone/personal music player?
|
There's an element of good luck to it, or serendipity. You feel like the universe is doing you a little favor. Also, if a song is on the radio, or a movie you like happens to be on TV, you know on some level that you're part of a larger audience. It becomes a sort of rudimentary version of a communal experience, which humans tend to find more enjoyable. That's also the reason why you prefer to see certain events on live TV, as they unfold, even if in fact you're all by yourself.

Why is it easier to wash dishes with hot water?
|
The hot temperature combined with soap helps to dislodge grease which may have congealed onto silverware and plates. Grease becomes less viscous as it is heated and thus easier to wash off.Hot water helps with washing for the same reason that slightly cool frigerators delay spoiling. I'm not sure I'm remembering this exactly correct but the density of excited energy states above a greaselike activation level for water at about 40^o F is about 300x' higher than it is for water at about 10^o F, so if you're just trying to dissolve grease or something the water simply doesn't have enough Umfhp when its cool. The same thing happens with lots of chemical reactions. Warm water brews faster, methane gas combusts faster when its warm, cold blooded creatures can move a lot easier when they warm up. Soap and enzymes mitigate this problem and allow cold water washing. Agitation works too.Hot water works best because when you are washing dishes you are primarily trying to remove grease and oils as opposed to "dirt". These oils can solidify or congeal at lower temperatures and melt at higher temperatures. When the greases are liquids it is easier for you to push them around making more surface area for the soap to dissolve the grease allowing for it to be washed away with water. *this is ELI5 so I have omitted discussion of non-polar vs polar substances and the creation of micelles etc etc

Why does the return trip feel faster than the trip to the destination?
|
Well son, I don't think that is always the case but . Remember when we went for ice cream and you were so excited you couldn't wait to get there. It seemed like it was gonna take forever, right? Then on the way home you were just relaxing and not thinking so much about ice cream any more, then suddenly you're home. It's because you're mind was at ease. This is really true for going to a place you haven't been before. It seems to take a long time to find your destination because you're busy checking out the route, making note of land marks, worrying about making wrong turns but once you know the way, it goes by really fast most of the time.I am making an educated guess. I am thinking of a drive from Houston, TX to El Paso, TX . On the way out to El Paso we passed through San Antonio, then Kerrville area, then across the low desert through Junction then across the higher deserts through a series of small towns and landmarks. On the return trip all of those landmarks, towns and cities had a reference. I knew for example on the return trip that the windmill farm we saw on the way there was about 2 hours out of El Paso, and so we had abut 8 to go. When we got to Junction I knew it was going to be about a 6 hour drive from there, then from San Antonio a 3 hour drive. Between SA and Houston is a very familiar drive we have made many times. So I believe it is the unfamiliarity of the outbound trip and the familiarity of the return trip that makes it seem faster. Also on the return trip you are anxious to get home. At least I usually am.Are you talking about driving or flying . When it comes to flying, there's differences in wind patterns and air pressure and some other stuff I'm making up that makes one flight longer than the other.Because you went west! Side note: I have no clue.
|
Why does cabin pressure change during a flight, and not stay the same?
|
To keep the air inside the cabin at sea level pressure would require planes to be much stronger . Letting some of the air out reduces the strength needed to prevent leaks, and it's still enough air to keep the people alive inside.You can essentially have 2 options. 1)have the cabin pressure set at an altitude, which is fairly constant. Until you get higher than the set altitude, the cabin pressure will decrease. 2)have the cabin set at a constant differential pressure to the actual outside pressure. So what ends up happening is that the cabin slightly pressurizes to set the door seals and whatnot. This happens as soon as they push from the gate. Then the cabin reduces i pressure at a somewhat constant rate until it is equal to 10000 feet or so. 10000 feet is what is considered to be safe for humans without danger of hypoxia. If you have an unpressurized cockpit, 10000 feet is your ceiling altitude set by the FAA. I may have sone minor details wrong but thats pretty much how it works.

Why does a rocking motion facilitate sleep?
|
I imagine that it has something to do with the development of an unborn child in the mother's womb. In what way is it comfortable to sleep? - in darkness, in warmth and with rocking motions, three attributes of the inside of the uterus. You spent the first nine months of your life sleeping inside of there. It's only logical that your subconscious pines for its relative safety and comfort.Nobody knows it seems, not even scientists who have studied it. _URL_0_ Maybe its something to do with rhythm which is soothing, like a heartbeat.For babies, it makes travel easier while in a mother's arms. There's no particular reason to suppress that instinct as an adult. Cats relax when you pinch their neck for the same reason.

Why can't I build a custom cellphone when I can build a superior laptop or computer for cheaper than most name-brand equipment?
|
The "you can" comments are missing a major component set that makes phones VERY different from your standard computer. RF and antenna matching gets really fuckey if you don't know how to tune it properly, which requires patience and relatively costly equipment. If you are an RF engineer who has access to this . Barring the analog and RF front ends- it's basically a computer. Do-able, but tiny, and therefore tough to pull everything together and make it play nice without many a ducat. Very important - it also has to pass rigorous network and FCC specifications and go through what is called "type approval" with the major carrier/s. Now in terms of getting it all to play nice, there is work being done to keep a standard interfacing between the different parts , but you will also be fighting various levels of firmware on the baseband/transceiver/apps processor, depending on how the phone is configured. Ultimately, IMO, best-case scenario - you may have a decent pocket computer that sucks at making calls and accessing the networkYou CAN actually. Good luck figuring out how to get the OS on there though.I'd like to see a source on building a superior and cheaper laptop with custom parts. The problem is miniaturization; you don't care about how big or power-hungry your desktop is, but phones and laptops need to be small, portable, and efficient. This means custom made parts, built specifically to mesh with each other. You *could* make your own laptop by fitting a bunch of parts together, but there's no way it would be both cheaper and better than something that was mass manufactured.Well Google is still working on the ARA project which enables you to atleast customize what modules you want to put in your cellphone. Worth checking out: _URL_0_', "It's possible, but there aren't plug+play standards like PCI. At this level you need to make your own schematics and circuit diagrams.

Why does it take so much time for the death penalty to actually kill said person?
|
Because it's a little permanent. The proper steps have to be taken to ensure that the person you kill has actually done what he's been convicted for. It's already a barbaric practice, don't need to add even more innocent deaths to it.* the state wants to be really, really sure before issuing an irreversible penalty* there person is locked up and can do little harm, so there is no hurry* some very motivated people oppose the death penalty, and will provide the condemned with legal resources not available to other prisonersdeath penalty cases are automatically appealed, which means the entire case has to be re-reviewed to uphold the original judgement. Just the appeal process can take quite a while.

What makes something romantic?
|
Romance is easily subjective, so it's dependent upon the receiver of the romance to find it romantic. A woman may find flowers from her significant other romantic, but she may REALLY find it romantic when he does the dishes. I don't think it can be easily defined by one act or style of gift. It's really all about the person you're trying to romance. My husband has of course given me romantic-style gifts, but the things that really stick to me as romantic are certain things he's said to me. We were watching Dr. Phil or some shit about women being beaten by their husbands, and he was so disgusted and said, "The idea of me hitting you or hurting you in some way actually makes me feel sick inside." This stuck with me way more than any flowers or candy he's bought.

Why are the majority of people right handed?
|
No one is quite sure. The science of handedness is still in its infancy. What is known is that it probably has something to do with *brain lateralization*. Brain lateralization is where certain parts of our brain specialize in certain tasks, such as the left side of the brain dealing with verbal processing and the right side dealing with vision and spatial reasoning. Right-handed people tend to be very lateralized , whereas left-handed people to have less lateralized brains, their brains seem to show neither hemisphere of the brain becoming dominant in some area, both play a part in everything. So the theory goes that lateralization is probably the "typical" way brains develop, hence 90%+ of humans being right-handed. There are some very interesting correlations with handedness, but I must stress, these are only *correlations*, we have no way of knowing whether they are actually related. But it seems that left-handedness is correlated with high creativity, and a disproportionately high number of US presidents have been left-handed or ambidextrous. LGBT people are also unusually likely to be left-handed. Ambidexterity is rare, but ambidextrous people tend to have brains that look a lot more similar to left-handed people than right-handed ones.

Can you explain the identity relation in philosophy?
|
Lets say you have two objects, Object A and Object B. The two objects can be anything you want. Now, depending on what Object A and Object B are, there are "relations" that describe how the two objects are connected to each other conceptually. For example, if A = Fire Truck, B = Ambulance, then one relation that could describe them is that they are both emergency vehicles. Now, if the names Object A and Object B refer to _the same object_, not just the same type of object , but the same actual object, then the relation between them is the identity relation. It's the connection a given object has with itself.

Why is there a separate security code on credit cards? If the three extra digits make it that much more secure, why not just make the number three digits longer?
|
In the olden days, credit cards were often not scanned with the mag strip, because the equipment was still too expensive for smaller retailers. What they did instead was use a carbon paper and a roller machine to take an imprint of the front of the credit card with the numbers. This was commonly part of the receipt, and one copy would be torn off and given to the customer. The problem with this, of course, is that now all these receipts you are just throwing away left and right have your whole card number on them. This is where the extra numbers on the back to confirm an online purchase can be used, if you only had a receipt you found with the front of someone's card, you would not have all the numbers needed to complete a transaction.

Why does the prime minister of some countries appear to have more power than the president?
|
Broadly speaking, there are three main systems of government around the world. There are Presidential systems where there is a president who is head of state and head of government . There are Parliamentary systems where the head of state and head of government are separate. The head of government is a Prime Minister or equivalent, and the head of state is either a constitutional monarch or a president. The head of state typically has limited power , but is generally meant to make sure the government doesn't overreach its power. Then there are Semi-Presidential systems which is somewhere between, where both the President and Prime Minister share responsibilities for actually running the government. Singapore, Malaysia and India are all parliamentary countries, so it's their PM who sets their major policies. The USA is presidential, and France is semi-presidential. Of course there are some countries that don't follow any of these systems, and there can be a lot of variation within these categories, but most countries do fall into one of them.

The concept of spin as it pertains to particle physics.
|
Think about the *state* something is in. For example, a car can be traveling at 10 meter/second. It is in this *state* of traveling at such velocity. Now, some states are continuous in nature, i.e. the car might as well be traveling at 9.98, 9.99, 10.01 meter/second and so on. On the other hand, some states are discrete by nature. for example, a light bulb can either be on or off. Spin is such kind of discrete states which sub-atomic particles can be in. Although it is named *spin*, nothing is really rotating. It is named as such because some of its properties resemble that of a rotating body.

Why can paper only be folded 7 times, no matter the size of paper?
|
Contrary to popular belief, this isn't true. The thing is, though, that the number of sheets on top of each other and therefore the total thickness that has to be folded increases exponentially . This means that you need a really, really big sheet of paper to begin with if you want to fold it more than 7 times, because otherwise the paper will just tear and stuff. Using thinner paper also helps. Mythbusters sort of busted this myth. They used a sheet the size of a football field I think and managed to fold it 11 times if I remember correctly. If you want to be able to fold it 12 times, you need a sheet the size of *at least* two football fields, but it isn't impossible. Edit: There are a lot of corrections in replies to my comment. Thanks for the corrections. I won't update my post, so to potential readers: just read the replies to get accurate info! There are also good replies to other answers here. And of course, google is your friend.

Old school graphics explanation. I need clarification please.
|
You have a grid of 320*200 pixels. That's 64000 pixels. Each pixel is either on or off, so you need 1 bit per pixel, for a total of 8000 bytes You also divide the screen into 8*8 color cells. Each color cell has 64 pixels, so there are a total of 1000 color cells. Each color cell has a foreground and background color. The foreground and background color require 4 bits each , so each color cell needs a byte to store the foreground and background color, for a total of 1000 bytes. Therefore, to store both the bitmap and color information, you need 8000+1000=9000 bytes. EDIT: Thanks to whoever gave me gold for this

Why do some trucks have a sign on the back that says "Work vehicle. Do not follow." What is the point?
|
Construction areas can be confusing, especially at night. People have a habit of following dump trucks off the pavement into the work area because the truck is well lit, visible, and moves like he knows where he needs to be. Source: I drive gravel trucks for a road crew in the summers', "They sometimes stop in the middle of the road. The idea is that you shouldn't get too close to it.

Why do peoples faces turn red when nervous or embarrassed?
|
Generally when you're nervous or embarrassed, you probably feel like you're in a high-pressure situation. The body responds by releasing adrenaline and increasing blood flow which causes your face to redden and your heart to pound.It is a "Fight or Flight" instinct reaction that is programmed down deep in your DNA. Being nerveous or embarrassed is a gut-level fear reaction. A stressful situation. You don't have time to think. Your body responds to this stress by instantly sending blood to your brain so it gets more oxygen to calculate options better and faster. Your face is very close to your brain. All this blood being sent to your head at the same time is actually observable through your skin. The red is actually the red of real blood being sent to your brain.

Why does one's hair become white as one ages and why does it happen to individual hairs at different stages?
|
As we get older, our follicles stop producing pigment. It occurs in different people at different times, in different locations, for different reasons. The primary factor is aging, and the scientific consensus is that all humans will only grow grey or white hairs if they live long enough. Actually, the absence of hair pigment makes the hair technically clear, not white or grey. The hair appears to be white because of layering and light refraction. Grey hair is the result of the mixing of the "clear" hairs with hairs it is layered with that still contain pigmentour scalp is constantly producing hydrogen peroxide along with a chemical to counteract that. as we age we stop producing the chemical to counteract the peroxide so our hair starts to become grey, especially unevenly.

"Jimmy Legs" (Restless Leg Syndrome)
|
In all honestly, we don't know what causes restless leg syndrome. There are certain things that can make it worse, but the initial cause hasn't been found yet. There may be a genetic component. Continue to experiment with different therapies to find one that helps, or at least figure out if there is anything that exacerbates it and refrain as much as reasonably possible. EDIT: because it's not fully explained by science, beware of pseudoscientific claims.

What is the point of a "D" grade in colleges?
|
Some majors will accept D grades for non-essential classes, like if you're studying journalism and you get a D in organic chemistry. You need no functional knowledge of organic chemistry to do your job as a journalist, so the major may be forgiving if you do poorly in that particular class.

Why cars don't have built in breathalyzers to prevent drunk driving.
|
Because it'd be weirdly invasive to try and force people to buy cars with what amounts to a monitoring system and it wouldn't be effective; you can't police everybody full time and make sure nobody tampers with it to deactivate it or give false readings.

Why is there such thing as activation fees? Where does it originate from?
|
Originally, it was because there was a cost to set up a product or service. It wasn't all instant or quick and easy to do like it is now - getting a phone set up or programmed took time and certain knowledge, or involved a lot more physical work to properly install and program a SIM card or the like. For other things, like cable or telephones, it might have involved someone coming to your house to actually make the physical connections needed for the service. In modern context, though mostly companies recognized it was something they could charge for, and people will pay it, so they charge it because they can, even if the original problems or costs involved had nearly vanished.Getting somebody set up with a product or service often requires a certain amount of maintenance and upkeep on the infrastructure side of business. Maybe certain equipment is used. Maybe dedicated staff manage the onboarding. Either way, work will have to be done, and somebody needs to be paid for it. So, rather than letting setup eat into the profits, companies merely pass on that cost to you.

What is happening at the cellular level when a body part "goes numb" from being too cold?
|
The blood supply to the nerves and nerve endings/receptors that mediate sensation is diminished, they get less oxygen and loose function. The nerve cells needs to constantly replenish its energy supplies through active uptake of nutrients, this relies on molecular pumps in the celle membrane that work poorly in low temperature. It's the same with the pumps in the membrane that constantly pump calsium in to the cell, sodium out of the cell and potassium in to the cell - they have less function in the cold and so the electrolyte difference between the inside and outside of the cell is not upheld and due to this the nerve cell is not as easily able to create and electrical impulse and propagte this impulse along the cell membrane. Sending nerve impulses is an active process dependent on oxygenation. Also, in lower temperatures the propagation of the electric impulse along the nerve is slower and less effecient due to the physical effects of lower temperature

Why does a federal court mediate this Tom Brady deflategate case if its a disagreement of league rules and bylaws.
|
Because the players union is suing the league. Courts are the ones who get involved when lawsuits are filedWhile it is a dispute within the organization, the conflict is that of a contract. When Brady got his contract, it stated that he would follow the rules of the NFL. Brady not following those rules would be like a man having a rule of "no smoking in my house" and the carpenter coming in and building him a new set of cabinets, but smoking. While it's a dispute within the household, it comes down to someone failing to uphold their end of the contract, and that goes to a judicial court. If a court can't make a decision that lasts, it goes higher and higher until it reaches the Supreme CourtCourts resolve contractual disputes between private parties all the time. Why would this be any different?

What are contraceptives and how do they work.
|
There are many different sorts of contraceptives from condoms to hormonal birth control to intrauterine devices. Condoms and similar devices work my preventing the passage of semen. Hormonal birth control, such as the pill or patch, work by disrupting ovulation. Intrauterine devices work by either disrupting semen or disrupting ovulation.

How can a "lazy" dog finish 7th in a 1/2 marathon, competing against humans? Aren't bipedals much better at traversing longer distances?
|
If I'm not mistaken dogs can be pretty good at covering long distances so long as it's not too hot. Humans main advantage to their stamina is being able to keep cool by sweating. That may not be the only reason but it may help you understand the logic behind the dog competing in a marathon during the winter", 'Humans are good at running down other animals over long distances. However, in this case, "long distances" means "a hundred miles over several days." A half marathon is only like 13 miles in an hour or two. In the old African plains, that counts as a sprint.

Why do Americans celebrate Thanksgiving?
|
Thanksgiving celebrations were an old European tradition even back in the 1620's . A Thaksgiving was a celebration made to recognize particularly good luck - the end of a war, an especially good harvest, etc. They were generally characterized by a day of prayer or religious services followed by a community meal. The pilgrim's Thanksgivings were in this spirit . Churches continued the practice until the late 17th century and after that, it wasn't uncommon for governors to pronounce a day of Thanksgiving every year or two . During the American Revolution, there were a number of Thanksgiving proclamations by both British governors, colonial politicians, and churches. At the close of the war, George Washington made the first proclamation of a national day of Thanksgiving - but that was a one-time deal. After that, there irregular state-wide Thanksgivings held in various states, and Canada adopted the practice. It became a regular national holiday after the American Civil War by proclamation of President Abraham Lincoln who was pestered by a magazine editor, Sarah Josepha Hale, to do so. While Americans still hold onto the imagery of thankful pilgrims dining with their Amerindian neighbors and the first Thanksgiving , Americans recognize Thanksgiving as a very old tradition, one that evokes community, family, thankfulness for those that are close and good fortune. It marks a seasonal change in the US where much of the country prepares for the upcoming winter and transitions to more indoor activity. Anyway, who doesn't enjoy parades, football, and sharing a big meal with lots of people?

How come a Wi-Fi repeater uses the same channel as the router?
|
Personally I would never use a wireless extender because they are not very reliable. What I would use is a wired extender. One that connects to the first router via ethernet cable and works as a second wifi connection point. This is known as bridging. In this case you can change the bandwidth and even SSID and it will work just fine. Or you can even use the same bandwidth and same SSID and keep it far enough from the first wifi so the signals do not interfere. In this form you can get any cheapo regular router and turn it into an extender based on the first router. You can even extend from the second extender to a third extender and to a fourth and so on. And since they already have ports built into them you can also connect other devices to them through ethernet wire. I've done a six routers deep bridge and my connection was as fast as if it was connected directly to the first router. Setting up the routers into extenders can be something that is not for the faint of heart specially if you want the dhcp server to be configured by the first router. This is preferred otherwise each router can be considered its own private LAN that cannot connect to the computers on the other extenders/lans. Although, there are some newer routers with a built in configuration option to set them as slave extenders. I'm no expert on any of this. It's just stuff I learned on my own. So if I made any mistakes on any of this jargon and information, please correct it.

What happens to wax in a candle after it burns away?
|
When you burn wax it turns into carbon dioxide and water. Most of the mass is carbon that ends up in carbon dioxide. Neither water vapor nor carbon dioxide will bother you much if you breathe them in.The wax is the fuel itself so it gets burned up. Candle wax is a mix of paraffins of different lengths. When wax burns the paraffin gets split apart into smaller fragments which react with oxygen and produce mostly carbon dioxide and water. Somewhere under 2% by weight of the paraffin doesn't react with oxygen but instead forms lumps of carbon that we call soot. Different waxes produce different amounts of soot -- bees wax tends to be closer to 0.1% soot. The problem is that if there is too little soot the flame doesn't produce as much light. Below 0.000001% soot and the flame doesn't look yellow, it's just looks blue like the flame on a propane stove.
