How do game developers link between graphics and code? | This is a massively complex question for which any answer suitable for ELI5 isn't really going to do justice to the substance of the subject matter. Think of the graphics engine in a game as a machine that builds Lego sets on demand. When given the instructions to build a set, it will throw out the set it just built an... |
Wouldn't atoms theoretically form elliptical due to gravity like other objects? | As I understand it, at the scale of atoms, gravity isn't really significant compared to electromagnetism and the strong and weak nuclear forces. Gravity only becomes significant at that scale in extremely dense matter, as you might find in a black hole. |
How could the governments of USA / UK have given such large payouts to the banks when they failed and then the money go to large bonuses to the people who were responsible for the failures? | Money was given to the banks because if the banks collapsed it very likely would have destroyed the econonomy. The money wasn't just given to the CEOs, although a portion was. I'm not going to say what Occupy was against or not, as I feel like it was broad enough that there would be plenty of interpretation there. But ... |

Why is sugar a primary ingredient of things that are not sweet or traditionally don't include them | Many of the more favourable taste sensations we get from food are caused by a mix and blend of various flavour-carrying chemicals. Some tone down others, others cause mild flavours that are there to be stronger. For example, the best chefs sampling a dish might add a little lime juice to their stirfry because it needs ... |
Why can I sit at home and drink 10 beers and it not affect me in the slightest, but go out to a bar and drink the same and feel significantly more drunk? | It also may be the rate at which you drink the bees. A consistent and even 10 beers at home may be different than how you drink at a bar. If you "front load" your drinks early at the bar they will hit you differently. Drinking your first 4 or 5 beers in the first hour is going to make the night go differently.Drinking ... |
Why, when looking towards an approaching storm,does it seem that everything in view is in 'HD' and when looking away the vision is less clear? | The area "under" the storm has a lot less light. This results in a lot less scattering and reflection of said light. When you have less reflected light bouncing around and hitting you from all angles things appear crisper. This is very akin to the affect a polarizing lens has. Typically when you look out towards the ho... |
Why was the #MH17 Plane shot down? | Rebels with little to no military training were provided with anti-aircraft missiles by a completely unknown foreign power that rhymes with "Dussia." Since the people operating this equipment were not very well trained, they couldn't tell the difference between an enemy military plane and a commercial jetliner and, as ... |
Why are Atlantic City casinos dropping like flies? | A big part is the presence of online gambling. It's very expensive to go to Vegas to gamble when you can so easily do it from home, even more to fly there. It's a different experience, sure, but you save a boat load of money and can still gamble. And a lot of local governments are looking to sponsored gambling to incre... |

why is it when in complete silence you hear a faint ringing or buzzing noise? | _URL_0_ You cannot always ascertain the cause just by knowing there is a ringing sound though. So I haven't really explained why you hear sounds, I've just given you a name for it. You should probably ask a doctor or someone to examine you if you cannot simply adjust to it . |
How can such an oil-rich country as Venezuela be in such dire financial straits? | Because of bad policies. Price and currency controls as well as a lot of other stuff like land redistribution and state seizures of property more broadly have led to dramatic contractions in just about every industry. Once the oil price fell such that venezuelan oil was no longer profitable, state subsidies could no lo... |
Why are ships always referred to as "her" and "she"? | > "thar she blows" - that's a whale > "I just got her waxed" - wax a ship? I suppose you could might reduce drag! 😁 Ships being female is an English thing stemming from the romance of men at sea. The old joke also that says: *"A\xa0ship\xa0is\xa0called\xa0a she because there is always a great deal of bustle around\xa0... |
How exactly do people actually support El Chapo, and want him freed? | like Escobar I imagine he Won over the public with privately funded benefits/welfare for the poor using his drug money, Robin hood tactics I think they call it.The same reason people support organizations like ISIS and al-Qaeda: in areas that are treated poorly by the government criminal organizations provide state-lik... |
How are LEDs able to be any colour? | They actually don't change color, they are actually 3 small LED's, one red, one green, and one blue; so just like pixels on a computer monitor, they mix together to form a bunch of colors. |
Why do people feel more compelled to smoke cigarettes when they're drunk? | For me I would have to say that it's an urge to smoke something. Whether that be weed, a cigarette, or vape. Also the nicotine rush that a cig gives you when you're drunk is just great. |
Harvard's major astronomical discovery made today | Well, [here] is the big discussion on reddit's Front Page, but it's not very ELI5. I haven't had time to do much reading on it, but here is an analogy, as I understand it. Suppose you had an explosion on the surface of the Earth that threw a cannon ball straight up. Gravity would immediately begin slowing the ball down... |
Calling cards and how they make calling other countries cheaper. | My understanding is that instead of routing through the teleco's network, you're effectively ringing a local number which then routes over the internet to the destination and ring out from a local number there and connect you to your desired party, so that way the company only pays for two local calls with the internet... |
How can you get a lot of calories from peanuts if they seem to pass right through? | Food is energy for our bodies. We measure that energy in calories, or the amount of energy needed to raise the temperature of a gram of water by a single degree Celsius. Some food is better at storing that energy in a compact form. For the sake of example, a gallon of water won't contain as much energy as a gallon of o... |
What happened with the Eurozone summit deal about Greece's debt and what that means for its people. | According to the [BBC], the Greeks agreed to a deal.

I don't understand what an economy is... | Taken from [Simple English Wikipedia]: An economy is a system of exchange of things of value. To better understand how the economy works, it can be broken up into three sections. These are: * the primary sector: which covers raw products from farming, fishing, and mining, and so on. * the secondary sector: which covers... |
Why aren't all grocery products labeled with a "Best by X date" rather than "Sell by X date". | Because those dates mean literally nothing. They're mainly "freshness dates" determined by the producing company through taste tests, but sometimes are just picked arbitrarily. Listen to the newest episode of the 99% Invinsible podcast; these dates are the focus of it. |
Why can't over-the-air radio or television be received on cell phones? | They do have FM receivers. But they're disabled because carriers want to be able to charge you for data you use by streaming audio _URL_0_ |
What are the differences between 4chan, 7chan, and 8chan? And are there other -chans I don't know about? | First, there was **2channel** . 2channel was an **imageboard** for the **Japanese**. [It still exists!] However, when **2channel** looked like it was going to shut down, people created the **Futaba Channel**, which was also in Japanese. This time, it focused on the more "redneck-y" part of Japanese culture called **ota... |
Why do some places (like supermarkets) have cash-back but don't charge a fee? | Because it is beneficial to them as well. It saves them the time and fees of depositing cash.The supermarket has already absorbed the cost of the fee when you made your purchase. It's simply a cost of doing business for them. Since debit card transactions tend to have a flat fee, it doesn't cost them any more to simply... |
Why do college textbooks cost so much money? | Mostly it is because they have a small market, and are expected to update every year. But also just because they can.Three points: it's a niche market, a captive market, and a dying business model. * Compared to other items, college textbooks are a relatively small market, so there are few economies of scale to lower t... |
Social anxiety in humans from very, very old times | No, throughout history we have been closer to our roots and things like social anxiety didn't exist as we either had to concentrate on surviving or had the freedom to create . Sadly in the last ~100 years society looks down on people creating things or puts it behind expensive obstacles, we have also in the last 200 ye... |
Why does store bought orange juice taste so bad compared to juicing an orange yourself? | "Fresh" orange juice that is "not made from concentrate" goes through an interesting process. The oranges are squeezed, but then the juice needs to be kept for months. To do this the juice is put into large tanks and the oxygen is removed. While this does mean the juice won't grow bacteria/yeast/mold, it also makes the... |
How does Dominos Pizza Tracker work? Or is it not even real? | They have buttons to press on their display screens that tell them what to make. In theory it's real and shows the real names of the people that are really logged in. But how real it actually is depends on how much you trust a bunch of teens to actually take it seriously and keep logged in as the right people and to no... |
Why do japanese voices (especially females) have totally different/weird voices ? | I don't get what you mean by "weird". You're going to have to be more specific than that as we may have different views of "weird" |
Homeschooling to someone who lives in a country it doesn't exist - it's illegal, actually. | I was homeschooled for some years here in California, United States. My mom, at the time, only had her bachelor's degree, and was a teacher, but many other parents we were around were not teachers yet taught their children at home. Homeschool can mean a number of different things. There are charter schools which are sh... |
Why does music sound slower when I'm running? | I've experienced this too. My guess has always been that with an increased heart beat/adrenaline, it's almost like your brain is capturing more frames of reality per second. This is how slow-motion video is created: more frames are captured per second, and when those frames are played back at normal speed, the subject ... |
Why do muscles get sore the next day? | Muscle fibers tend to be this type of longish cells.When you work out and go through several cycles of lengthening and contraction of the fibers some regions will be weaker than others so you will have small tears within your muscle.

Why shit burns when having diarrhea? | A few reasons. If you have diarrhea when you're sick, you could be pooping a lot, wiping a lot, and therefore rubbing your b-hole raw, making anything that touches it burn.

If Putin really is having critics killed, why is he doing it so publically? | Putins controls, or is "friends" with someone who controls major media conglomerates, so the propaganda is in a heavy thing. If you want to know more about how it is, read some articles on RT.Who's going to stop him? If he is behind it, it sends a pretty strong message to people who are thinking about speaking against ... |
Would have any benefit from having a 3rd eye? | I suppose it depends where your third eye is. Even if we had an eye on the back of our head it would only benefit if we were constantly being chased by a predator. Rabbits have 2 eyes but since they're on the side of the head they have nearly 360° view. Animals have 2 eyes for depth perception. So nature just modifies ... |
How do credit card readers never charge the wrong account? | Credit card numbers have check digits. There is a mathematical formula that has to be correctly solved to verify that the card number is valid. If the formula can't be solved, it disregards the entire number, and you have to re-swipe. |
Why are automobile engines made with cylindrical pistons? | The function of the cylinder is to contain a little gasoline explosion, directing the force out in on direction . A round shape is the strongest shape for containing the explosion, because it has no weak corners to crack, or weak flat areas to bulge out. A linear shape is necessary so that the piston can then move up a... |
Why does balding seem to affect primarily the top of ones head? | The genetic reason is that the hair follicles there are sensitive to the hormone that makes people go bald. They're just different from people who aren't balding. This is why hair transplant clinics can take hair from the back of your head and put it on top of your head and it will grow normally. The sides and back of ... |
who is in charge of the cables in the ocean that connect the internet to different countries? | The owner is. Someone owns these cables and charges for their use, or uses it for their own ends.

Why was there such a backlash for Google Maps and the estimated calorie counter for your walk | From what i can gather it was claimed that it was triggering to people with eating disorders,and it also didnt take into account each person's bodyweight and age to calculate it. |
When people collect signatures, how do we know they didn't forge a bunch of them? | We don't know that. For petitions that actually do things the government audits them by taking a few pages at random and checking them against voter rolls. Then they take the percentage that are accurate on those pages and extrapolate it to all of the pages. If they find a lot of bad signatures they look at the rest ev... |
why aren't full service gas stations more common across America? | > it would solve a lot of issues from unemployment Not really. It would create a small number of extra jobs, but would also inflate the price of gas to cover the cost of all these new people being employed. It could have the effect of just reducing gas consumption, which could then cause a *drop* in employment in vario... |
How does the golden ratio follow the fibonacci sequence? | Take two successive numbers of Fibonacci sequence, 13 and 21 for example. 21/13 will be close to golden ratio. Kepler proved that limit of ratio of two infinitely large successive Fibonacci numbers is golden ratio, or lim{n - > inf} F{n+1}/Fn = phi. EDIT: More general form, as wikipedia says, is lim{n - > inf} F{n+a}/F... |
Why is chiropractic viewed as an inferior form of medicine by many physicians? | Chiropractic is effective for treating certain types of back injury. However, chiropractors can sometimes make claims about the alignment of your spine causing ALL illness. And that's just not true.Because it is inferior - at least a big portion of it. That is much of chiropractic theory is unverified or not reproducib... |
How did people discover that some poisonous foods (such as blowfish) are edible if prepared a certain way? | As far as I know, the most poisonous parts of blowfish are the organs, which sequentially tend to be eaten last. Most of the meat itself isn't all that toxic, as its not the blowfish itself that is deadly but the bacteria present in its organs that it itself is immune to. Even in primitive times, it didn't take a geniu... |
Why is bigamy illegal? | Legal: Marriage is a contract between two parties. It's an agreement that has benefits, protections and consequences within the law that are defined by having two parties. Involving a third party means different laws. Societal: God thinks it's bad. |
If cat's and dog's hearing is so much more sensitive than human hearing, why are they not bothered by things such as traffic noise or TV noise? | Cats and dogs can hear a wider range of sound frequencies. That does not necessarily mean that they will experience noice to be any louder then what we experience it to be. Also, dogs tend to not give a f*ckTheir ability to not give a f*ck is also much more advanced than ours.Same reason why dogs aren't completely dest... |
What does the "key to the city" actually do? | It's purely ceremonial. You have to realize that this wasn't always the case. About a thousand years ago, most cities were protected by walls. There was usually only one or two ways of gaining entrance to any city. This was either a locked door or gate. This is because back then anyone arriving could have been a barbar... |
Would Dr. Evils plan from the first Austin Powers really work? What would happen if it really did? | It would do absolutely nothing. Earth is a massive celestial body and we simply don't have enough firepower to affect it in a meaningful way. Sure, an all-out nuclear war would crash the ecosystem but Earth, as a planet, wouldn't care. Detonating a nuclear device in the core, as unrealistic as the entire scenario is, w... |
How did insects evolve to resemble plant life? | Insects with mutations that cause them to look like plants are eaten less often than insects that aren't. This causes the plant-mimicing-insects to have more offspring that themselves look like plants, whereas the non-plant-looking-insects do not, because they were eaten by birds, and are now dead and therefore can't h... |
how does the sound from a music file travel through earbuds or headphones | Oh I see the confusion. The sound isn't created by the computer. The earbuds convert electricity to music. The computer outputs electricity that looks like the sound. The earbuds have a "voice coil" which is a coil of wire which floats inside a magnet. It looks like [this:].The coil will move in and out because electri... |
when I rub my eyes sometimes I cannot see anything around me but only sparkles and darkness for a couple seconds. | The cells responsible for seeing are constantly being sort of 'recharged constantly. Putting pressure 'disintegrates' the cell and renders it ineffective for a while. Even with normal pressure this is happening all the time but balanced rate of disintegration and regeneration. With added pressure,like rubbing, the rate... |
Why most of the series debut episodes are named ''Pilot'' | . > A pilot experiment, also called a pilot study, is a small scale preliminary study conducted in order to evaluate feasibility, time, cost, adverse events, and effect size in an attempt to predict an appropriate sample size and improve upon the study design prior to performance of a full-scale research project .

- Why does stretching feel so good? What's happening in our muscles that gives such a sense of relief? | I'm not 100% sure but the neurotransmitter dopamine is highly responsible for gated muscle movement . Although muscle contraction is more directly accomplished by the neurotransmitter acetylcholine, the release and surge of dopamine may have something to do with the feeling. |
How can spiders pull their string across such big gaps? | They start spinning a thread and let the wind catch it, carrying it to wherever it's going to land. They do it as the first step of building a web: the top of the triangle that the rest of the web will be built upon. Sometimes those first strands are too long, so they abandon them and try somewhere else. Sometimes you'... |
What is the difference between boiling water and microwaving water? | There are some good but half finished answers in here. 1. There is no difference between water that is boiled in a kettle, and water that is boiled in a microwave. In either case, it is just hot water. There is no radiation in in the water, it is just hot water. 2. It is possible to superheat water in a microwave, wher... |

How is it that my Reddit app is able to see the uncensored image for a brief second & how is it being censored? | It looks like the OP originally posted the uncensored image, decided that that was a bad idea, and updated the image on imgur to be censored. But reddit caches images, and your reddit app shows the image that was cached by reddit while it's loading the one from imgur. So you see the original, cached image, immediately ... |
why is it that some animals freak out at the sight of their reflection, and others barely seem to notice? | It really depends on the animal some like dolphins may realize that they're looking in a mirror and be intrigued. Most though, don't understand "mirror" as a concept. Then you have the following perceptions and reactions: 1.) The animal has good eyesight, and sees its reflection -Social animals like dogs will often try... |

What are the differences between consumer-grade CPUs made by AMD/Intel and Digital Signal Processirs made for industrial/military purposes? | You seem to be confusing two things: - general purpose CPU vs DSP. DSP are CPU whose instruction sets and internal architecture are particularly well adapted to signal processing. For such kind of application, they are more powerful than usual CPU. You probably have several in your home - ICs are usually designed to wo... |
Why can you often hear a steady, high-pitch, low-volume ringing sound in complete silence? | You might have [tinnitus], which is fairly common condition with any number of causes. I've had it most of my life, and it's not a big deal or even really noticeable except in complete silence. |
Why are states electing to ban the sale of Tesla vehicles? | States ban the sale of Tesla based on the fact that Tesla sells their cars to the person directly as in there is no dealership. The association for dealerships lobby hard to get these banned because they figure that if Tesla can do this, than other car makers can start doing the same ergo no more car dealership and no ... |
Why don't bugs splatter from falling proportionally equal distances as a human jumping off a building? | Because they hit the ground with significantly less force because they weigh less . If the ground were to hit the bug with the same force that it hits you, the bug would die. If you were to drop just chuck one of your legs off the roof, it also might not break when it hit the ground . But..if you put the entire weight ... |
What happens to guide dogs and K9 units that fail their training? | Then they get to be normal dogs for a lucky family. There are special websites and societies that specilize in either ex K9 unit dogs and/or failed graduates. [One Example] We raised German Shepherds when I was a kid. We did a lot of testing on very young pups to try and understand their hardwared behaviors. Good follo... |
How do bugs even survive in nature? | Insects don't have the "intelligence" approach to survival like us. They have short lifespans. A female cockroach can lay 300-400 eggs in her lifetime.

Out of sync flipbooks do not make convincing motion, which we perceive as flickering. |
How sunburns occur, and why they can cause pain for days after receiving the sunburn. | When you get a burn, what you are doing is causing damage to the DNA in your skin cells. There is a chemical called thymine that is one of the bases in your DNA. When it is hit by UV light, it can get knocked out of place and attach to a thymine next to it. This forms what is called a dimer. When many dimers form in yo... |

Moreover, they are allowed to obscure their id... |
If sleeping is good to do when you're sick, how come your immune response makes it so hard to sleep? | Currently have a cold: chills, headache, congestion, soreness, and a cough. I want to sleep but I'm miserable. |
Why do some people sleep in certain positions better? | Sometimes ways of sleeping are just nicer because that is what you got used to.

But also when you get older, you might try out different positions and start liking them. I like sleeping with my a... |
Why is mint often associated with Christmas/Winter? | I am just taking a guess here but many people brink a Christmas tree into their house which has a somewhat minty smell so maybe the association happened that way. My other theory would be that peppermint sticks were white and red which were also Christmas colors so people bought them for decoration. However it would be... |
What's the difference between a "declaration of war" and "military engagements approved by congress?" | War has a lot less red tape in the US, but a lot more with other countries.

Why does brushing through tangly hair make so much noise? | All sound, as you can hear it, is a form of displacement. But more relevantly if you notice softer hair tends to be a bit quieter after a few brush strokes.

Why do cats enjoy sitting in empty boxes? | It feels safe to them. The same idea that they feel hidden when they have just their head under a blanket or in a bag.

What does isis gain by destroying ancient statutes and burning ancient books? | ISIS, like many other Sunni Islamic terrorist groups subscribes to the Wahabbist school of Islam.

why we think we look worse when a picture of us is flipped ie from a forward facing camera? | I think "worse" in this context is just how jarring the differences are.

algebra. conceptually, why is it permissible to combine equations? (example inside.) | Let's get rid of the algebra, and just use numbers: 1) 30 + 40 = 70 2) 2 + 3 = 5 Now we can add these together, and we get: + = 70 + 5 This is exactly equivalent of your example, where we take two equations and add them both together. Hopefully you can see how it works here. It works with your example in the same way a... |
Why is cable internet (which travels over two copper wires) faster than DSL (which is also just two copper wires)? | It's more about the type of signaling used, and the type of wire. Coaxial cable the signal is on the inner wire, the outer braided shield helps protect against interference. IP over cable tends to be also a cleaner network, as far as how the signal gets from the cable company, to the head end to your house. DSL tends t... |
ELI5: when people from warm climates have extra low tolerances for cold weather, is there an physical cause for their sensitivity, or is it psychological? | It's a physiological cause. There are hormones created in the thyroid gland that activate genes that code enzymes that are involved in glycolysis and ATP production. This effect is called the **calorigenic effect**; the cell consumes more energy and generates more heat. For example, children who are born in colder clim... |
Why do some people sink, and some float? | Your body is probably denser than hers, muscle is a lot denser than fat so people with a low fat content don't float as much as people with a higher fat content. |
Why do we find things like a emergency warning to be creepy or eerie? | It's more the association of a warning with something bad. For example, if the first time you met a puppy, it bit you really bad, the next time somebody said lets go get a puppy, you would probably be nervous. The same thing applies when hearing a tornado siren, when in previous times you heard it, there was a tornado ... |
Why do most car commercials advertise the leasing price of a car if most consumers buy, instead of lease, their cars? | People that buy their car tend to keep their car for a long time. Let's say 4-6 years on average. People that lease switch cars every 2 to 3 years. Say 2/3 of people buy their car and 1/3 lease. Since the lease terms are half of typical car ownership periods, that means over 4-6 years, there are just as many leasers lo... |
