Why does Japan seem to have such a low proportion of immigrants when compared to other developed countries?
|
[
"Japan is a very (ethnically) homogeneous society and was essentially closed to foreigners for more than 250 years. Foreigners are not made to feel particularly welcome there. Anyone \"different\" stands out like a sore thumb."

[
"While very large and rich in resources, it has fewer people than Argentina, Poland, or Sudan. There are cities in China with almost as many people as Canada. In addition, culturally, politically, and diplomatically, they are similar to their close allies the US and the UK, and don't have much to add to what those countries are saying on the world stage."

Does laying in bed resting before you sleep actually do anything to rejuvinate your body for the upcoming day?
|
[
"Sleep is mostly important to renew the brain neurotransmitters and do some housekeeping around the brain. When you think about it, sleep is mostly about shutting down your consciousness. We are only starting to understand what really happens in the brain during sleep. Conclusion: laying in bed is rejuvenating your body without doing much for your brain."
] |
[
"You can't really get too much sleep. It is not bad for you. Sleepiness and alertness are affected by hormones and these hormones can change if you over tax yourself or change your sleeping, eating, or exercise schedule in any way. Sometimes if you sleep more after a taxing week, like exam week, your body may take this as a cue that it is allowed to go into a lower gear and you may feel sluggish and your immune system may even be weaker. It is hard on your body to be \"working\" all the time producing cortisol and keeping your immune system top notch - even good stress can tax your system. Relax to give your body the break it needs or use mild exercise to see if that gets rid of the feeling more quickly."

Why does our fingernails have faint lines going up and down?
|
[
"well first you should know that its normal. Evenly spaced vertical lines are never a sign of a problem (But horizontal lines, you should see a doctor.) What happens is that as you get older, parts of the nail matrix (the part of your fingers that the nail grows out of) atrophy. They become weak and dont function quite as well. This results in the increasingly prominent vertical ridges. They're very similar in this way to skin wrinkles. Just the natural result of the aging process."

Software Installation
|
[
"Most apps store data all over the place. A Steam game is going to have an install directory, a save game directory, drop dll's into a systems folder, update DirectX, and change registry settings. A flash drive is only going to handle one of these, the install directory. This isn't necessarily a bad thing, it makes it easier to do stuff like uninstall the game without losing your saves. It also serves as a form of DRM. Game producers don't want to make it easy for games to be portable without going through them or a service like Steam."

When floating in space, or any zero gravity environment, would a person always feel as if they were standing upright?
|
[
"You would feel as though you were falling. \"Zero-gravity\" actually means you are in free fall, or in a motion that imitates free fall, such as the planes that fly in steep parabolic arcs to simulate zero-g for short periods of time without having to go into orbit. Imagine you jump down an elevator shaft that just goes on forever. That's what being in zero-g feels like, and that is why people often feel sick/throw up when experiencing it."
] |
[
"The plane, when doing a flip like this, exerts centripetal force on the thing inside the plane. That acts as a kind of artificial gravity which is the g force you were talking about in the description. The pilot will still be pushed into the bottom of the plane, just like the water, no matter how he is oriented. As long as the plane is spinning, it should work. You can try this your self by taking a glass and a grape or something similar and spinning the glass around quickly and then raising it up a few inches. The grape should remain in the glass for the same reason the pilot and water stay in the plane."

How does a child get a recessive gene if both parents have dominant?
|
[
"Passing on a recessive gene means that they are both carriers, giving you the lucky 25% of cases that would have the thumb."
] |
[
"It doesn't cause them. It exposes them. We all have mutations, but we also have two copies of each gene. They are called alleles. If your parents are not related, it's unlikely they will have the same bad copy. If they are related, they could have both inherited the same bad allele from their shared ancestor. Mutations usually result in losing that gene's normal function. As long as you have one good copy, you do fine. If you have both bad copies (the same mutated version) you're SOL."

what happens if you leave the microwave door open and it's turned on?
|
[
"Microwaves are electromagnetic radiation with fairly large wavelength. If you take away the spinning mechanism and put in something like a block of cheese, you'll pretty reliably be able to see that the heat will most be applied in certain sections. If you measure the distance between those sections, you'll be able to tell the wavelength of the microwaves. What'll happen if you leave the door open? Microwaves will leak out. What does this do to you? Well it affects the water in your system which definitely can't be good for you, but it isn't a HUGE deal. It'll also really fuck with the wifi at your house so long as the microwaves are leaking out"
] |
[
"She's absolutely right. Microwaves are extremely harmful and can kill you or cause serious health problems in seconds. They are cooking appliances, and being inside one will result in being cooked. This is why you should never put a cat, dog, baby, hamster in a microwave. This is why you should never stand inside of a microwave. Luckily, most microwaves have doors that keep the bad stuff in, and are too small for you to fit into. Also, most (working) microwaves prevent you from turning it on with the door open. Don't ever take a microwave apart and try to make it work without the door or casing. As far as eating food that was in the microwave.... totally safe. It's converted to infrared energy (heat) in the food. BTW you shouldn't sit inside an oven either, that will also kill you. You also shouldn't stuff yourself into a blender, stay in the freezer for hours... I guess the general rule is \"don't use kitchen appliances on yourself\"."

How does a vinyl record work?
|
[
"Vinyl should be the easiest to understand - the waveforms are etched directly into the vinyl. Open up a music file in a viewer like Audacity - you see that waveform? That's what is etched into the vinyl. The needle gets moved up and down (and left-to-right as well for stereo records) and the vibrations are carried to some electronics that amplify them. In fact, if you take a record player with no power whatsoever and spin a record, you'll be able to hear the music directly from the needle (but it'll be very very quiet)."

Why is haggling something that just doesn't happen any more?
|
[
"Market efficiency in action. Used to be if I wanted to buy something, I didn't have a lot of choices. There were no supermarkets or shopping malls, and I was pretty much stuck with wherever I was willing to walk to. If a seller was charging more than I wanted to pay, I couldn't just go somewhere else. Luckily, the seller was stuck with me too. If they wanted to make a sale, they might not be able to count on a bunch of other people walking through the door. The only real alternative either of us had for getting a better price was to argue about it. In addition, a lot of sellers were selling goods they made themselves, which gave them some flexibility. If you are selling something for $10 and paid $8 wholesale, you rarely will sell it for less than that. But if you paid $1 for materials and put an hour of your time into it, you still might want to sell it for $10, but selling it for $5 isn't losing money."

Why are computer and calculator number pads in the opposite order of phone keypads?
|
[
"The original calculator had a 1x9 column of number buttons for each digit, with 1 at the bottom and 9 at the top. To make an 8 digit calculator you had 8 \"5\" keys in a row. When calculator people figured you could use one \"5\" key if you did numbers in order with a \"0\" key, they folded the 1x9 up into a 3x3 grid with a \"0\" (and often a \".\") below it. At that time, phone dials were rotary. Bell did a huge experiment with both formats, but only a very small fraction of society had ever used a calculator (math was done with pencils at the time). They decided on the 3x4 grid with \"1 2 3\" at the top because that was the pad that most people used most quickly/correctly. Then calculators became digital, and cheap, and it was noticed that these two big systems were different. Alas, neither could agree to change."

Why are autopsies almost always definitive? How come they can give answers when biopsies and other medical procedures can't?

Instead, they look at the symptoms, compare it to other cases, and then make a prescription. If the medicine works, great! If it doesn't, they discontinue that script and try something else. It is not reasonable to assume that \"most\" cases are misdiagnosed. The \"scientific evidence\" they have is in matching the patient's symptoms against other cases. This is how most medicine works. If you walk into a clinic and say, \"Doctor, my knee hurts,\" he won't just cut your knee open to see if the bone is broken unless he has some reason to do so. Psychology and psychiatry are admittedly ambiguous and highly dependent on the patient's self-reported symptoms. That does not mean it is quackery."

That's not the answer to your question though. Many talented artists spend their 9 to 5's painstakingly crafting these ultra high quality 3D models of spaceships, people, etc. It took years, and every year it gets a bit better. It's alot like making a painting just in a digital space, except that it ideally moves. The advantages to animation are many. Animation is the most free art form. The only limit to what you can make is in your imagination. The drawback is that series like \"Love, Death, and Robots\" are generally underappreciated by the general viewing public and do not make much money in comparison to how much they cost.

What makes some humans generally considered more attractive than others?
|
[
"It is just a tool of evolution. We are programmed to seek out optimal mates for reproducing, and we can dicern more than just physical attributes from looks. Just over 200 years ago, being obese to morbidly obese was considered very attractive, because it meant their family was wealthy and could afford to eat enough to make them fat, which was an uncommon thing at the time. It isnt even a conscious effort, our subconscious breaks down the subtle meanings and gives us either positive or negative feedback. These days, when someone is obese or morbidly obese (this coming from a former obese man and student of Philosophy, so dont get too offended), it no longer means they are incredibly wealthy, so we do not find it attractive. On the contrary, it typically (not always) shows that they lack discipline, have difficulty setting long term goals, and struggle controlling their impulses, all traits that would effect a partner negativley when trying to reproduce and raise offspring. The mind is a fascinating thing."

why water completely damages a cell phone when submerged.
|
[
"Electronic circuits are designed to only allow electricity to pass through certain parts at certain times. That's how your phone works. It's a set of boolean functions (1 or 0/true or false). Electricity passes through chip, and it makes a decision such as \"and/or\". If it's 'and', it sends the signal one way, and if it's 'or', it sends it another way. After it does that, this step is repeated through other logic gates that have other functions that aren't and/or (not/or or any of the many other variants). Once you submerge it into water, it doesn't follow this designed 'trail', and the phone short-circuits. Because water is conductive, the electrical signals go wherever they can, and electronics can't handle that. To make something of a comparison; It's the same reason you get in a line when you're shopping. Imagine if all the customers just threw all their items onto the counter at the same time and talked over each other. The cashier wouldn't know what to do. That's what the submersion is."

"You are not legally entitled to most government benefits; you must be eligible. If not using illegal drugs is a condition for eligibility, then you can be required to prove that to obtain the benefits. That's not unconstitutional, because you're not being compelled to do anything--it is your choice to seek the benefit of the program. Mandatory tests for intoxication without any suspicion are highly questionable, but that's a very different situation. Going about your lawful business and being required to submit to a test is not the same thing as applying for a benefit and having to submit to a test to prove eligibility."

He didn't get involved until Ja-Rule said in a song \"Em, you claim your mother's a crack head, and Kim (his wife at the time) is a known slut, so what's Hailie (his daughter) gonna be when she grows up?\" And nobody talks shit about Em's daughter so Em got involved and verbally tore Ja a new asshole with his song \"Nail in the Coffin\" and also \"Hailie's Revenge\"."

Since China landed on the moon I've heard talk of helium-3 mining. What are the practical applications of helium-3 and why would we need to go to the Moon to get it?
|
[
"Helium-3 is used in fusion research, neutron detection, cryogenics, and medical imaging according to wikipedia. Helum-3 is one neutron short of being normal Helium-4. Helium-3 fusion is attractive for a few reasons. First, there are no radioactive byproducts. Also it can lead to direct electrical production as opposed to using fusion to generate steam to drive a generator turbine. So it's theoretically more efficient. Neutron detection is important for detecting radioative materials like plutonium. He3 gets colder than He4, to within a few tenths of absolute zero. If you inhale it it shows up in an MRI and can be used to image the air ways and lung passages. The reason you need to go to the moon to get it is that it's even more rare than regular helium. Helium is light enough to escape Earth's atmosphere and float off into space. He-3 is even lighter."

"In order for a planet to have oil it would have had to have supported life at one point in history. And it would *never* be worth it to extract oil (or any other raw mineral), unless it's some kind of yet-to-discovered exotic matter. The amount of energy required to get to the planet, and then bring its resources back to Earth, would far exceed the amount of energy provided by the mineral or required to synthesize the material here on Earth. Nearby asteroid-mining on the other hand could be incredibly viable, but we'll never be able to mine an energy source (just precious metals, etc.)"

In regards to firearms

[
"A lot of differences between weapons are in areas that don't feature so much in games. For example the cost, the weight, the distribution of the weight, whether or not the ammo is the same as for other weapons, the weight of the ammo, how easy it is to take apart and clean, how often it requires cleaning, etc. Even on areas which are shown in game stats (accuracy, damage) there's more or less variation than shown in games. In accuracy there's all sorts of differences between weapons that appear identical (bolt-action rifle users are always harping on about accuracy). Meanwhile, in terms of damage, in the real-world there's a lot less variation than in games, as almost any bullet (maybe not .22 rimfire) is capable of ending someone."

How exactly does fat exit my body after a workout?
|
[
"Fat (triglyceride) is made up of Oxygen, Hydrogen and Carbon. When 'burned', the fat is combined with Oxygen from the atmosphere to create CO2, which you exhale. About 85% of the weight you lose is exhaled as CO2. The remaining ~15% is turned into water, which you expel in your urine."

Why are 7 and 13 considered lucky and unlucky respectively?
|
[
"this is a cultural thing and if you travel to various parts of the world you'll find the same does not hold true for them. for instance, Chinese and Japanese consider 4 to be unlucky and not 13. The reason for that specifically, is because some of the pronunciations of 4 are similar or the same as their word for death. 13 may be considered unlucky for many reasons but a common belief is because of the christian religions \"last supper\" where jesus and his 12 disciples ate... judas, the one that betrayed jesus, was the 13th person to sit at the table. 7 on the other hand may be a rule of 5s type thing... i.e. people looking for certain patterns will eventually see them in just about everything. I also suspect christian religion has something to do with it though... I've heard many times how 6 (specifically 666) is supposed to be the number of the devil and so 7 which is above six, would be the number of god."

Why has the fasces symbol, which is often associated with fascism, been incorporated by so many official offices and institutions in the United States?
|
[
"You've got it backwards. The fasces was a symbol of power which the fascists adopted later, just like how the swastika was a symbols before it was adopted by the Nazis. It was a symbol of government power going back to the Roman empire, and the founding fathers, who attempted to emulate Rome, adopted it themselves. Mussolini did the same thing, but it was 200 years after the founding of America."
] |
[
"Historical context. White Power and White Pride are associated with racism because of a history of their use by racists. Consider the complaints about the Confederate battle flag. People say that it is just a symbol of Southern pride. But it was first flown on the SC capitol as part of the struggle against civil rights. The swastika is just an old good luck symbol common around the world, but became anathema in the west because of its use by the Nazi's. White Citizens Councils could have been simple civic organizations, but were, in fact, racist groups specifically organized to keep black people suppressed."

Prior to radios, satellite imagery, and other military technology, how did opposing armies locate eachother for battle?
|
[
"So, when you think of things like this, you're probably thinking of something like in the movies, where a few guys are moving through the woods or jungle or wherever and can hide their tracks. That's not an army. An army is *thousands* of people. A scout can find traces of 4,000 people walking somewhere -- either from just the massive amounts of tracks left, or the fact that someone will notice thousands of people on their way to somewhere, and one of those people will tell you about it."

"It's where satellites are, and satellites are the backbone of modern communications and photo-reconnaissance technology. The GPS satellites, for example, allow the US military to guide vehicles and weapons to anywhere on the globe with a tiny margin of error. That's a *HUGE* advantage in a fight. Reconnaissance satellites orbit constantly and collect images of whatever the owner of the satellite wants pictures of. Being able to shoot down, damage, or confuse your enemy's satellites seriously limits his ability to gather information. As for space combat, at the moment it looks a lot like slinging missiles (or potentially laser beams) at your enemy's satellites/unmanned spacecraft to disable or destroy them. We're a few lifetimes away from spaceship dogfights."

If Tupac is dead, who receives the royalties when someone listens to his music? And same for other deceased artists

[
"Tupac's estate was managed by his mother until she died a few years ago. Control of the estate then passed on to a a trustee that his mother appointed before her death. His mother and now the trustee was the beneficiary of all financial gains from his estate as well as empowered to make legal decisions regarding copyrights, release of previously unreleased music...etc. Most artists have similar situations in place. Many artists and musicians continue to make millions of dollars a year even decades after their deaths, and they usually have wills that provided instructions for how to manage their estates. For those who die with no will, a court usually grants control of the estate to the next-of-kin, or may divide it up between close relatives if there's a dispute, although disputes can drag on for years."

It is one of the services that the firm offers, and unless the firm agrees to take you on as a client ($$$) they are not going to waste their time or get involved in the situation. Additionally, I've heard that there can be legal repercussions for a firm that gives out bad advice to clients, so no law firm is going to take that risk without payment."

Why is what's going on in Ukraine right now not already considered war?
|
[
"It's not a war because Russia hasn't formally declared war on the entire country and has only moved units into the eastern portion currently being contested. If they insert unmarked units there, it's not war because they still officially deny that the units are theirs, meaning that they're supporting the rebels by proxy. Ukraine, NATO, and most external observers know that they're Russian, but even Russia doesn't want a formal declaration of war. It's what the new kids call a 'low intensity conflict'. This is different from full-scale conventional warfare in that they are restrained from using their full capabilities for political reasons, and their operational area does not include the entire country or engaging its national forces. Granted, this particular conflict is going to be a lot hotter than what are normally considered 'low intensity', but it looks as though Russia doesn't want to commit to rolling over the Ukrainians with their considerable amount of available forces."

"If you ever look at the ISS sighting times for your city, you will notice they are always early morning or late evening - never the middle of the night.

Can black holes bend light from planets so we are actually seeing them in the wrong place?
|
[
"This is an occurrence known as gravitational lensing and isn't specific to black holes, but any object with significant mass. Objects whose light is bent do then appear in the \"wrong\" place. We can even see objects (stars, galaxies) that would've been otherwise obstructed (blocked) from vision if lensing didn't occur."
] |
[
"We know about them because they emit electromagnetic radiation or they absorb/bend radiation from other objects. That being said, because nothing travels faster than light, we only have information about the state they were in at the time they radiated. So if you're seeing objects that are a milion lightyears away, you see them as they were a milion years ago. So some of the stars that are shining on your night sky might not even exist now."

They fight unconventionally, have no regard for military/civilian targets and are only looking to protect their business empire. The cartel Los Zetas, alone, are notorious for wiping out entire villages (men, women, children...even animals) and stringing the bodies up from local bridges if they think a region is getting too uppity. Basically, reword your question as \"Why is it the American military has so many problems with Afghan insurgents? Why don't they just eradicate them.\".

Why metal is forbidden from the microwave.
|
[
"Not really an expert on this, but basically the way microwaves work is they send a lot of microwaves (duh) across the heating chamber. This makes the particles of items inside move a lot faster and therefore raise the temperature of the item. This works fine for foods etc, but for metals accelerating the particles means creating electricity. All that electricity cannot be contained inside the metal (since it is a conductor, which means it only passes the current along). This causes the electricity to escape in form of sparks. I don't think I need to explain to you why sparks flying freely inside an electronic device can be dangerous ;) Hope I made it clear enough?"

Can someone explain the fall of the Soviet Union (like I am five)?
|
[
"It was extremely complex, but some simple reasons are: - The Soviet occupation of Afganistan, which was an incredible failure, costs a ton of money, and left the nation demoralized. - The arms race with America, which further drove up the nation's debt. - Internal conflict, economic troubles, problems with the fundamental basis of Communism - Several Soviet leaders, mostly Gorbachev, enacted [reforms](_URL_1_) to attempt to modernize, and head towards capitalism. This kills the crab. So ultimately, it wasn't just Reagan smashing the Berlin wall with his bare hands. It was a long, complicated series of wars, economic woes, and debt."

"> both involve a machine to learn certain tasks and evolve over time and get better at it. False. That does not apply to AI AI most often refers to a process that can evaluate and intelligently react to its enviroment. A Chess AI will not evolve over time and get better. It will not learn chess from the ground up. It will be given an algorithm to scan the game for possible good moves and is programmed to be able to evaluate the current board, but it does no organic learning. Once you start the AI it will never change its skill. Machine learning involves the computer learning patterns and discovering its own solutions trough a wide array of strategies and via trial and error. AI can do that, but is just ad apt to describe computers who are told the method to find the solution beforehand. Machine learning is a sub field of AI research. It is one tool in a toolbox, but AI does not need it for all tasks and in some tasks it is just the wrong tool."

The ridiculously high and growing suicide rate in Japan.

Why doesn’t stereo volume stop at a point before distortion occurs in stock speakers? Conversely, why don’t stock speakers hold up to the capability of their stereo counterparts?
|
[
"Manufacturers often make more variety of speaker than head unit, so low quality speakers are often paired with more powerful head units. They want to keep the overall system inexpensive, but they're not able to get a cheaper head unit."
] |
[
"When you play audio, the speakers are vibrating up and down. Loudness is made by how much the speakers are moving up and down, so if it's louder, the speakers require more power. Assuming you're not using an 'audiophile phone', with a higher quality amp, and not using audiophile grade headphones, your phone probably can't provide enough power to the speakers, or the speakers can't take enough power. This can 'overload' the speakers and cause distortion. This can also break the speakers if you do it a lot."

Dimples on a golf ball, how do they work?

[
"There was a wonderful mythbusters on this, I can't quite remember the mechanics however. The dimples reduce drag, which is a force in opposition to the balls movement caused by the air around the ball. I believe, but I can not be certain, that the dimmples break up the 'profile' of the ball when it flies through the air. This causes less of a slipstream tail behind the ball, which is where much of the energy gets consumed by drag. But I would have to check my facts and I'm sadly on my phone. The mythbusters episode was quite good though if you can find it, they covered a car in dimples by the end of the test to see if it would get better mileage"

Why is Republican leadership voting to approve Obama's budget?

This is beneficial to Republicans who understand what would happen if there market meltdown if the U.S. credit is downgraded again. * It \"Cleans the barn\" for Speaker Ryan. That is to say it gives Speaker Ryan a relatively clean slate to start working on bigger spending cuts and mandatory spending reforms with the Freedom Caucus.

How does Flonase work?
|
[
"Flonase is fluticasone, a corticosteroid. Basically it's a synthetic derivative from a class of chemical naturally occurring in your body which function to regulate immune response, among other things. When you have a stuffy nose due to allergies is because your immune system is over-reacting to the allergen. Fluticasone acts on immune cells etc to reduce their activity (anti-inflammatory / immunosuppressant). For example, the excess fluid is often caused by substances released by immune cells that cause your nose blood vessels to become leaky, so fluid can get out and clog up your nose."

For example you can make a chart with speed on one axis and time on other, and they are still valid dimensions. They are just a concept, they do not actually exist."

Why do race cars omit airbags in their cars?

"The purpose of an airbag is to keep your head from slamming against the dashboard and causing an injury.

How high and far could you jump on Pluto?

"Gravity on Pluto is about 1/15 of gravity on Earth, or about half of the Moon's gravity. If we assume you can put the same energy into your jump as you can on Earth, you'll leave the ground at the same speed and jump 15 times higher than you can on Earth. You're also in the air for 15 times longer, so if you also take off with the same horizontal speed as you can manage on Earth, you'll jump 15 times further. I suspect that with enough practice (and really good running spikes) you'd actually be able to run a bit faster on Pluto because you could put more of the energy from each stride into forward motion and less into upwards movement."

When did a tax break ("we'll take less of your money") become synonymous with a subsidy ("we'll give you someone else's money")?

"I cannot answer the \"when\" part but can address the \"why\" part. People think of a subsidy as a deviation from the *status quo,* not from a baseline of zero. So if government has decided to tax everyone at 10% and this becomes the norm, and *then* government decides to cut a certain party's taxes, it can be thought of as mathematically equivalent to taxing that party at 10% and also giving them a payment. Since this is ELI5 I will make no attempt to turn this into a discussion of right and wrong, etc., but that's why the term is seen by some people as valid in this usage."
] |
[
"It's very simple. Whenever someone says \"the government pays...\" or \"the government spends...\", picture it mentally as \"you pay...\" or \"you spend...\". That's because the government gets its money from taxes, and you're (likely) a taxpayer. So if the government spends $50 billion to bail out some bank or insurance company, that really means taxpayers spent that amount. Maybe they'll recoup that money, and maybe they won't. But the fact remains that *whatever happens*, the bank's fabulous profits go to the bank, not the taxpayers.

Now imagine that your evil house mate comes along and replaces that sticky note with a different one with the same name but a different phone number. Next time you go to call Bob, you don't bother with the book and just look at the sticky note that you thought you had. Only its been tampered with, and thus you end up calling someone else.

But they can also be used for *evil*. It massively pisses off users, so no reputable site would do it, but many sketchy sites have no reputation to lose, so they use it for one last chance to try to sell you something. You may have to click \"no\" a few times, but the people that make web browsers are aware of this tactic, and after a few they give you an option to ignore any further attempts by the site to keep you there."

Can someone explain this effect where a camera picks up the "reflection" of the eclipse, but not the eclipse itself? (Video and images inside)
|
[
"It's lens flare. Lens flare happens when you point a camera at a very bright light source, usually the sun. Some of the light from that source bounces around the lens, creating multiple images of the source along with rings, starbursts and other effects. A movie camera has a very complicated lens made up of many parts, so it can create pretty spectacular lens flare -- traditionally, directors and camera operators did everything they could to minimize lens flare, but these days it's often created deliberately to add atmosphere. Your phone has a very simple lens, so you're only getting the one reflection. (There may be a couple of others that are just too faint to see.) The light source itself -- the sun -- is still far too bright for the sensor, so it's overexposed and smudged out so you can't see the eclipse at all. But the reflection is much, much fainter so you can see the shape very clearly indeed."

"Well, when a camera takes a photo usually from left to right. It's doesn't take the picture all at once. So something can be one way in the picture on the left side, and different as it goes right. This is a great example of this effect: _URL_0_ When the photo was taken, the kids eyes were closed, but the reflection, which was scanned a fraction of a second later, he had opened them so that's what's seen in the reflection."

Why do fans cool us down if they're just moving the hot air around?
|
[
"you make air hotter and wetter. Yes you, you stinky human. You're sweating. you're producing heat. These things move from you to the air. But they move slower, the closer you are to the heat and moisture of the air. Heat and moisture transmit more readily to the air the greater the difference. So the advantage of the fan, is it takes the hot wet air you've gone and contributed to, and moves it away. Instead you're left with new, cooler, dryer air. And so your body can move heat and wetness to it faster. Thus cooling you."

"The engine loses energy when it constantly heats up the air blowing past it. If the engine was not losing this energy, it would be storing it, causing it to get very hot. When you use your fork to grab a hot piece of chicken, blowing on the chicken cools it down because the thermal energy in the chicken is transferred to the air you're blowing on it. The fins help because they create more surface area for the air to blow against the metal of the engine. This is part of the reason why your fingers and toes get so cold during the winter. There's a lot of exposed parts for the air to blow against. I don't know how fin angles work, sorry."

Why does my brain prefer songs that rhyme to ones that don't?
|
[
"It's probably a lot more to do with how you identify rhythm in song. You like the once that rhyme because that adds to the rhythm of the song, and is easier for you to identify. The language center in your brain might be slightly larger than the music one"

How come China population is so huge if Mao's Great Leap Forward killed 45 Million just less than 60 years ago?
|
[
"China's population had been in the hundreds of millions for [centuries](_URL_1_) before that. A lot of people died under Mao, but eventually they got things like food production under control, the [birth rate](_URL_0_) spiked and people didn't die of famine, so you had huge population increases. In the end, their population roughly doubled over the second half of the 20th century, which isn't actually so far removed from the US, which saw it's own population grow by about 85% over the same period of time."
