Why did video game developers stop using footage of real actors? Wouldn't that be the most realistic option for say, a FPS? | It'd be uncanny valley. [Beowulf] in 2007 was pretty much one-of-a-kind because it looked so close to realistic, but it was just that much off. Your brain is really good at picking up on the subtle failures of lighting and colouration that CGI can make, so you either spend way, way too much time and energy on CGIing ev... |

How does currency work in the world markets in terms of inflation, exchange rates, stocks, etc.? | If a bunch of people in foreign countries suddenly want to buy American goods, they're going to need dollars to do that.

When there is a breaking news story (or important event) how does a news channel get away with having no commercial break? Do they loose revenue? | Doing lots of coverage on an important event will make viewers like that news show more, resulting in more returning viewers when there is less exciting news on and ads run normally. |
How do currencies have different values/worth? | When you exchange currency from one country's to another's, the ones making that transaction, usually banks, are left with that currency you exchanged.

Since silverback gorillas have such humongous guts, how come they don't get diabetes, heart disease, and other obesity related health problems? | A thing to consider is time. A gorilla's lifespan is normally between 35 and 40 years. And health problem with obesity in humans develops over time but gorillas develops faster and humans usually don get obese at a young age.

How do some noises make your teeth feel
weird? | The only thing I can think of is [resonance frequencies]. Mythbusters did an episode on the myth that it was possible to break glass with the human voice, in which they studied how each object has a specific resonance frequency. Any time an object is affected by a sound or force at that frequency, it oscillates with th... |
Why do Modern Art exhibitions showcase pieces that lack technical skill? | Technical skill is not the sole criterion for judging the value of a piece of art.

I've seen this more and more, but why do people put their cell phones on speaker and then hold the phone an inch from their mouth? | I don't know about men that do this, but women do it so you don't end up with a phone covered in make-up and hair products.

How astronauts digest food in space | Astronauts eat three meals a day , just as they do on Earth. Meals are organized by the order in which astronauts are going to eat them, and stored in locker trays held by a net so they won't float away. When mealtime rolls around, astronauts go into the galley area in the shuttle's middeck. There they add water to fre... |
Why do Men Go bald on the top and sides of their heads but not in the "beard/mustache" areas? | It has to do with the follicles on that part of the head. Men with male pattern baldness have follicles on the tops of their heads which react to a specific hormone that causes them to recede and eventually stop growing hair . |
Photo analysis/Face detection algorithms (snapchat face filters) | I don't really have much experience in this field. But as far as I know it goes something like this: First of all the algorithm is trained on low-resolution images of faces from different angles. Several filters are applied to the training images to enhance facial features . Here's an example: _URL_1_ Now for the image... |
How was Thomas Young's light wave theory proven? | What was Young's experiment to prove the wave nature of light? The double slit experiment. If you don't already know what it is, two slits were made that were kept a very tiny distance from eachother, and using a single source, or two sources in phase, light was shone through both these slits . The observation was that... |
Why do rocket engines look so complicated if they're just an opening for a controlled explosion? | Because it's a massive explosion and everything massive is complicated to control. You need to be able to keep watch on and influence massive ammounts of fuel flow. You have to be able to control the direction somewhat . You have to take care of a massive cooling system too. And probably a lot of other things I can't t... |
How do chocolates (during the late 1800s) survive in temperate climates like in the Philippines without refrigeration? | [Ice box] It’s like a cabinet that has a huge area for one massive fucking ice block and then the other side has the storage area and below was water collection', "Now, for something that needs middling storage temperatures, like a modern chocolate bar, a cellar will likely keep it intact for some time. Chocolate of th... |
Why does the government provide “stimulus” to banks rather than just larger returns to low to middle income earners? | they did do that. _URL_0_*almost* everyone got $600 cold hard cash. Unfortunately this money was quickly blown, often on imported goods that did nothing to support the US economy. Quantitative easing was a more direct route to not just subsidize spending, but to facilitate liquidity for the market to operate naturally.... |
Why can I adore the smell of a certain food, but dislike the taste? Is there no connection between how a meal smells and tastes? | Aromas are much more complex than taste. But what we perceive as flavor is the combination of the two. Our brain smells coffee and appreciates the complex hydrocarbons from the roasted beans. Our brain tastes hot water. |
How were Double Role movies shot back in the day when their was no CGI | This is my first time posting here, and I don't know if you can post links, but I just saw a great video by "Crash Course" explaining how early cameras created illusions. It should answer your question. _URL_0_ |
How do we inherently know what notes to whistle? | There's isn't any "real" notes. Even the idea that everyone "should whistle the same notes" is only around 200 years old. Before that, every place had different notes they played on. The frequency "C" of today is absolutely arbitrary. Which means we don't need any prior information to whistle, everyone knows to just go... |
Why don't we put solar panels on wind turbines? | Some panels are placed on the supporting structures but placing them on curved surfaces isn't that easy. Placing them on the blades isn't practical for a whole host of reasons. |
Why are cats so fascinated by boxes? | The safest place in nature is a hole or cave where you're protected on 5 sides and only exposed on one. Evolution favors safe behavior like this, so it has become instinct. An open box is the modern equivalent-only open on one side, danger can only come from one direction, so they feel safe. It's also the reason cats w... |

Why do some languages adopt new words for recently invented items? | Quite often a word will be used that literally describes the object, or what the object does, this could be for convenience as sometimes the inventing country's word might be difficult to pronounce. In a few countries it is common to adopt the inventing country's word though. In fact inventing a new word might be for d... |
Why is the Linux OS so popular to use in science and research equipment? | It's really flexible, so it can be used more efficiently for highly specialized tasks. Also, a lot of research software is written for it. |
Why my pubic hair grows so much faster than my facial hair. | speak for yourself, its neck and neck over herePubic hair is the same kind of hair you have in your armpits and to a lesser degree your eye brow/lash hair, your facial hair is the same kind as your normal head hair, so they grow in different ways and to different lengths. |
how do we “forget” things? And where do those memories go? | Memories are formed by connections between cells called neurons in your brain. Each memory is a unique *wiring* up of neurons. When electrical nerve signals pass through the wiring structure you remember the memory. Your brain has an amazing capacity but it is still finite in size and has to prioritise the information ... |
What is the difference between a Loner, an Introvert, and an Antisocial person? | I think you might be confusing the terms asocial and antisocial. If you are antisocial you are being unkind or abusive towards other people. If you are shy you are being asocial.I'm would say a loner is happy in there own company but can handle groups fine.An introvert does not necessarily want to be alone but does not... |
Would a modern version of Spartan way be more effective, in theory, than traditional military effectiveness? | > easily the most effective fighting force in Greece Per unit, yes. As a whole, I highly doubt it. Spartans *were* badass as fuck. But there weren't very many of them. They only won the battle at Thermopylae because they had a terrain advantage. There's a reason they mass produce modern soldiers the way they do. A sing... |
If conjoined twins share a stomach, do they both feel full or hungry at the same time? | It's hard to make general statement about conjoined twins because literally every case is different, but the feeling of hunger is regulated by hormones, most importantly Leptin and Ghrelin, which circulate in the blood. So if the conjoined twins share their circulatory system , then these hormones will always affect th... |
Why are there so many different species of animals, yet we as humans are all one species? | There have been many different species of "humans" that did coexist at times. This site has a list of some of our relatives that died out along the way, with approximate times of extinction so you can compare and see which ones lived alongside each other, if you like. _URL_0_ Exactly why our line is the only one left i... |
If the primary colors are Red, Yellow, and Blue, then why are pixels made to only show Red, Blue, and Green? | RYB are the subtractive color primaries, which works with paints and reflective surfaces where adding more tends to make things darker. RGB are the additive color primaries, used on screens and projections, working with light sources where adding more tends to make things brighterPrimary colors as RYB is mostly just fo... |
Beveridge Model vs Single Payer system | The answer to your question is written in black and white in the links you provided.

Why do we have fiction stories (books, movies, games)? | Stories help us learn about the world and the values of our culture. Consider the movie *Twelve Years A Slave*. You could learn the details of slavery through a textbook and learn about the morality of slavery through moral treatises, but it won't have the same effect as watching a movie telling the story of a man who ... |
Why does the barometric pressure drop when a storm is overhead? | From what I understand, the pressure is not low because the storm is overhead. The storm is overhead because the pressure is low. Take a ziplock bag and fill it a quarter of the way up, the lay it on its side. If you apply pressure, the water moves out of the way to where there is less pressure. When pressure is low, t... |
How can we sense someone behind us even if the person is dead quiet? | You sensed it either through smell, sight, touch, or hearing. You may not have been consciously aware of it, but that's what happened. There's also a good deal of confirmation bias because you remember all the times you turned around and someone was there, but don't remember the times you turned and nobody was around. ... |
Why are peanut allergies so often really serious? | Peanut allergens, since they are a food product, can come in direct contact with the internals of the body. The swelling they cause can cut off the ability to breathe. And let me tell you, suffocation is a very serious problem that can kill you quickly.Sampling bias. You don't hear about the people with mild nut allerg... |
Why is Belgium a really powerful and influential country given the size as they are home of the EU headquarters? | It isn't it fact quite the opposite. It is such an irrelevant little country that it was *perfect* as the place for EU HQ. Putting it in Germany would have annoyed France and having it in Paris would have pissed off Germany and of course the UK would be pissed regardless . But Belgium well nobody can be offended by tha... |
Why do all deaf people speak with that specific tone in their voice? | They can't hear, so they can't hear the voice inflections that we all have. This means they have never learned how to properly use voice inflection. Instead they have just been instructed on how to properly form letters and words. This is difficult enough to teach someone who can't hear, and voice inflections aren't to... |
; why is it that people snore when they are asleep, but don't have the same breathing pattern when awake? | When people lie on their back the soft tissue hangs farther toward the back of the throat because of gravity, partially or completely closing off the airway. When people breathe in, the negative pressure flaps this tissue and causes noise, which is snoring. When people are awake gravity doesn't pull the tissue in this ... |
What is the receipt of retired pay? "Would you be entitled to receive VA disability benefits but for the receipt of retired pay?" | > "Would you be entitled to receive VA disability benefits but for the receipt of retired pay?"

Want to check if your answer is appropriate for a 5 year old audience? Use this simple tool to measure grade level of your writing. | Thanks! Alternatively, you can calculate an actual grade level of readibility by using the [Flesch-Kincaid Grade Level formula]. I don't know any good calculators for this online, but I do know you can calculate it instantly by pasting the text into Microsoft Office, and then spellchecking. You will have to change your... |
What happens in the engine if you put diesel in a petrol car? | If you have some petrol in your car and put diesel in it, it will start but smoke heavily through the exhaust. Damage will not be great to the engine though. However, if you fill in an empty tank of a petrol car with diesel fuel it will never start. If you've ever compared gasoline to diesel fuel, you know that they sm... |
How is it possible that I copied a file without copy all of its content? | I would make another copy, and get the user to try to put more data into the file as they had done before - see if it shows up. My brain goes to PICNIC error first here. If your system said the file copied successfully, then it most likely did . It's extremely unlikely for a copy operation to keep a file in a readable ... |
Why does it hurt getting water up your nose when swimming, yet having a runny nose isn't the least bit uncomfortable. | First of all, if you think a runny nose "isn't the least bit uncomfortable," you 've not had a real runny nose! It can be *extremely* uncomfortable. Now, your nose is designed to let liquids drop out, not to take them back in. When you get water up your nose, it goes into all the nooks and crannies that nothing's suppo... |
Why do dark-skinned or black people have their palms and soles paler than the rest of their body? | A layer of skin called the stratum lucidum is found in frequently used areas of the body, like your palms and the soles of your feet. The added protection of this extra layer means you don't need extra melanin in your palms or feet, so the skin is lighter. EDIT: To clarify. Melanin is what makes skin dark, and it prote... |
How does taste work? Why does a person A like spinach, but person B does not? | There could be a million reasons why someone doesn't like a food; maybe they ate it while feeling sick one time, and learned to associate the sickness with the taste. Perhaps they were made to eat something all the time as a kid so they're just totally opposed to eating it as an adult. The reasons could be either menta... |
How are ancient structures buried? | In dry, dusty areas the wind blows in sand and sediment. Once someone stops living there to clean up it will build up. People also like to build on river banks and river deltas, very fertile for crops and easy access to water, but the river brings sediments and floods. In some places a populated site persists for hundr... |
Taxi Medallions, what is this system? | There are large areas of NYC where only a taxi with a medallion can operate and they limit the number of medallions that they allow to operate in a given year. This registration system generates income for the city and ensures that there are not too many taxis on the roads of the overly congested city. Uber bypasses th... |
If English is a Germanic language, why is it so difficult to read texts/understand speech in other Germanic languages? | English is the dirty bastard of Germanic languages. It is not German, it is rooted in the same early language group that gave us modern German/Dutch/Icelandic and the rest. English was heavily influenced by the Romance language group, particularly through old French, when the invading Normans brought it along. Toss in ... |
What would happen if the Earth suddenly started spinning the wrong way? | If the earth stopped suddenly and started to spin the other way it would not matter because we would all be dead anyways.Suddenly?

Why is it that big semi trucks last for hundreds of thousands of miles, but some cars start breaking at just about 100,000? | I myself work in the mining industry in australia. Recently was at a site near coober pedy in the middle of nowhere. Maintenance is a big part of it. The road trains we had are tri-drive kenworth 908s or something but would do 6 trips a day so close to 600kms a day from site to rail siding and back a few times but ever... |
How can child-actors play in gruesome movies like Beasts of no Nation? | There are two routes. Danny from The Shining did not know it was a horror movie. His scenes were edited so that he did not have an idea that he was supposed to be in a scary movie. In Beasts of No Nation they went the opposite way. They were clear with the actors and explained what was happening. They made sure to have... |
Why do people in poverty stricken countries continue to reproduce even though they know their children are likely to starve to death? | Because if you keep reproducing, maybe you will get lucky and some of your kids will grow up to adulthood, get a wife, and farm the scrap of land you own and provide for you when you are old and can't work anymore. You know, like how people did for pretty much all of recorded history. |
What happened to all of the sweepstakes? | They were replaced by online contests through web forms and social media, which are faster, easier, and cheaper to both organize and participate in.Don't know about the US, but in the UK, this generally stopped after it was discovered that the TV shows where rigging the contests. _URL_0_", 'They ran out of money becaus... |
Why do people not get electrocuted when touching a charger? | There are two ways in which chargers prevent electrocution. The first one is that everything that can be covered in plastic or rubber is covered in plastic or rubber. Electricity can't flow through plastic or rubber. If something on the outside of the charger or device is metal, the charger will have a third metal stri... |
Why is the word "'nother" so typically said after "whole"? | This is an infix, a word inside a word to add emphasis . It is placing "whole" inside of "another," a-whole-nother. The only other common infix in English is "fucking," e.g. abso-fucking-lutely and god-fucking-dammitit is an English colloquialism typically the proper way would be either a whole other --as someone has m... |
Why is deforestation such a large problem if it only affects the country where it takes place? | First, it doesn't only affect that country; the entire earth benefits from having a healthy ecosystem. Second, the health of countries is intertwined; a desolate country that is economically desperate is going to affect adjacent countries. |
how and why animals age differently to humans, and how we are able to calculate their age equivalence? | If by "Age equivalence" you mean something like "dog years" that's simply a rough approximation. If a human lives 10 times longer than a dog, on average, then 1 \'human year\' is 10 'dog years.\' It really has no particular accuracy beyond a rough demonstration of lifespan, and tends to be wildly off on things like 'ma... |
Why don't invisible rays like wifi and satellite hurt humans or animals? | Does shining a flashlight at you give you cancer? Because visible light is actually on the "more dangerous" side of radio waves. Radio waves, like Wi-Fi, are the same thing as beams of light. The only difference is that we have special chemicals in our eyes that react with the electromagnetic waves we call "visible lig... |

Why do sitcoms have laughter tracks? | People tend to laugh more when they hear other people laughing. Laughter is a pretty social phenomenon. Most people are more likely to laugh at a show if it has a laugh track. I don't know how that equates to viewership, but it obviously has some effect or they wouldn't do it. |
Why does this appear to move? | It's an illusion that happens because we're constantly moving. Our eyes are jumping around the page while our body is twitching. If you stop all the movement and just stare at the picture, you'll notice it stops moving, too. Pretty sure it's a myth that the picture will move faster if you're stressed though. They proba... |
Why do we have that uncomfortable feeling when sleeping with limbs uncovered or hanging out of the bed? | Evolution. People who didn't get that weird feeling when dangling their limbs from the trees they were sleeping on were killed by cheetahs. |
why are most of the animals born with good enough insticts to survive at birth while humans are so helpless? | Humans are building a biological supercomputer, that takes time. Our great ape cousins are also pretty useless at birth, as are a lot of other mammals and birds. They're developing complex brains and behavior systems that can't be completed as quickly as basic body development.Part of the reason is that humans have to ... |
Early American territories and colonies. Who owned what, and how did they get it, and how/why did they lose it? ie: the Lousiana purchase.

How do police catch cars using false licence plates? | if you get pulled over, they run your plate and its not listed/different than what your car is you get in a shitton of trouble. you have to be really smart about it, because getting caught with a fake licence plate is often worse than whatever crime you were hiding from', "They see a car and are suspicious for some rea... |
How does a (particular) flock of migratory birds decide *exactly* when its time to go? | I'm not an ornothologist but I'm a human, and all ornithologists are also human, so that's gotta count for something, right? I'm guessing all birds have a number of "thresholds", with some variation from one member of the flock to the next. A: the temperature/conditions at which the bird would rather stay, but will sta... |
Can someone please explain the general ideas behind Healthcare Reform and why it is so controversial? | Some people think every citizen in a rich country ought to get health care, even if other citizens must help pay for it. That would require the government to collect money and then spend it on health care. Other people think it isn't fair to make one person pay another person's health insurance bill, or that the govern... |
What does a volume knob physically do inside a speaker to increase/decrease the volume when you turn it? | You're actually controlling a variable resistor, a.k.a. a potentiometer -- which can control the amount current in a circuit. Lower current = weaker sound, higher current = louder sound. Basically, when you turn up the volume, you're allowing more electricity to flow through the circuit that leads to the amplifier.The ... |
Why do people live in Places like Barrow, AK | Some of them might be Native or just have grown up there. For the most part, people live up there to harvest natural resources. Alaska produces a shitload of oil & has lots of mining. It's a rough place to live, so they make a lot of money. Many people that live in Alaska working those industries will work a few months... |
Why do processed food comes with tag saying "xKcal".

What's the difference between Linear Synchronous Motors (LSM) and Linear Introduction Motors (LIM) on launched roller coasters? | "Induction" not introduction. The synchronous motors generally know where the cars being accelerated are. The LIMs generally don't. LIMs are more grunty at the start, but can't generally get the cars going as fast by the end of the track. LSMs aren't as quick off the line, but can sustain higher speeds in the long run. |
Why NetFlix's "Recently Added" column has all the newest releases, while it's "New Releases" contains mostly movies that have been on NetFlix for months-years. | It's based off of your recommended shows/movies so if you have a specific taste, the newest movie in that category might be a year old. |
How does Eye color play into attraction? | Looking into someone's eyes can reveal a lot of information about how that person thinks of you. For example, if you look into your date's eyes and they dialate, you are *much* more likely to think they have pretty eyes. This is because eye dilation is a sign of arrousal in this context. Similarly, pupil dilation shows... |
the difference between Tylenol and Advil and when you use them | Tylenol's active ingredient is acetaminophen Advil's is ibuprofen, a NSAID They are similar, but NSAIDs help reduce inflammation.

Why are AK47s and other Kalashnikov weapons so renowned? How do you make your weapons simpler and hardier than the other guy? | The simplicity mostly comes in the form of HUGE tolerances between parts inside the receiver. If you open an AK up, there's a ton of empty space inside the receiver, and very few moving parts in the trigger group. That allows you to put all kinds of dirt, gunk, snow, sand, pebbles, dust, etc. inside the thing without g... |

What is the difference between oil drilling and hydraulic fracturing (fracking) as well as the difference between the methods used? | **Fracking:** imagine that the oil you want is soaked in a sponge. But this sponge isn't squishy , but it's also easy to break, like glass. If you drilled a hole through this "sponge" you will only be able to reach the oil in the pockets really close to the hole you're drilling. But imagine drilling a hole through the ... |
how did the very first life forms develop? | Well we have some idea. Infact, you could create life in you own kitchen! its very simple: take a tank, fill it halfway with purified water then, get a canister of pressurized carbon-dioxide. spray some into the tank, then quickly cover and seal the tank. Now, all organic life is composed of four main elements: Carbon,... |
Does FLAC compression have different bitrates? | FLAC has different levels of compression but they relate to how much CPU/RAM is used in the compression rather than the target bitrate. Since FLAC is lossless, it's not really possible to target a bitrate. As far as file quality goes, FLAC is limited by the quality of the input. If you have a CD, the quality will alway... |
Why did people think Beanie Babies would be so valuable? | Collector items tend to be valuable as they become rare.

Why does gas mileage take a nose dive during cold temperature? Is there an agreed upon temp where warming up the car is required? | There are a few things. 1) the above 2) The engine has an optimal temperature below that temperature it runs rich to warm up faster.3) cold air has a higher oxygen content so you need more fuel to create a good burn. More fuel means worse mileage. This only really translate to 5-10 percent difference but it all adds up... |
Why are many manholes placed right in the path of a car's tire on roads? | I don't know for sure but I'd guess it's because the tunnel is under the road and the ladder down is on the side of the tunnel. Which more or less places the ladder under your tire, apparently.Why is the worst possible location or even a bad position. Have you notice a lot of manhole coverts that breaks or get damages ... |
Do caterpillars know that they are going to become a butterfly? If so, how? | It's a common mistake that people sometimes make to try to apply human levels of intelligence to insects.
