Why do airplanes store information on a "black box" instead of streaming it to somewhere on land? | Reliable wireless links are few and far between when you're a long, long way away from civilization the way airplanes frequently are. Sattellite airtime is expensive, and you could never truly depend on it the way you can a black box.Very simply: sometimes planes lose contact with ground control. Therefore, there is no... |
How can The Hershey Company trademark a color? | A trademark is some sort of identifier for your product that you wish to protect. In this case, that particular color of orange is associated with Reece's peanut butter cups. So Hershey's got a trademark so that no one else can use that color of packaging to sell candy. Note that trademarks are industry-specific so I c... |
Why do people talk in their sleep? | Basically it's just an extension of dreaming. During certain periods when we sleep, our brains create a series of themed visions that bring in elements of our world and experience.

How is it that fiber can both help you with constipation and make your stool more solid? | The fiber cannot be fully broken down by your digestive system, so it basically just passes it on through your body whole. This process helps to "push out" other waste material, and thus helps with constipation. Meanwhile you have these whole strands of fiber that are not broken down, that get mixed up with the rest of... |
Why do people think Michael Jordan bet on basketball? how did it play a roll in his stint playing baseball and in his retirement? | I'm from Chicago, and I do know that MJ was quite the compulsive gambler. There were local stories here all the time about his betting on everything from golf games to poker to horse racing. Naturally, the rumors led to his own sport. All speculation, never proven. |
In an era of paid DLC and season passes, how can video games like Minecraft and Terraria continue to release free content without losing money? | Many large titles are in debt by the time they release, and expect sales and recurring income streams to repay that deficit. This was not the case for Minecraft, which started selling to customers very early in the development cycle. Also, Markus Persson maintained a day job during the first few months. Currently, Mine... |

Why is it called an Ethernet Cable and not an Internet Cable? | Because they use the [Ethernet] standard to provide networking. You don't have to be connected to the Internet to use Ethernet cables and protocols to connect multiple computers together into a network. Prior to Ethernet, it was common for offices to use [Token Ring] networks. Ethernet fixes many of the drawback of Tok... |
Why are house cats pretty much all the same size and shape while dogs come in a variety of builds? | Dogs want to please their people. It's just the way they are.

Why do cats paw at blankets or beds before they down? | Typically this is something that young kittens do to make milk flow more freely while they're with their mother. In older cats it's a sign of the cat being particularly at ease in its surroundings. Sometimes you'll even see a cat appear to lick the blanket at the same time. |
Why talking about sex to teenagers is still taboo in some culture ? | I can't speak for all cultures, but here in the USA it's because we're still trying to shake off the dual legacies of Victorian morality and Puritanism. Both of which we inherited in droves at the the founding of country. You 'd think in 230 odd years we 'd have been able to move on, but some people don't seem to want ... |
What is the Great Attractor? | Assuming you mean in an astronomy context The "Great Attractor" is the name given to a particularly large cluster of galaxies about 220 million light years away.

How effective is the British House of Commons and is their method of tackling politics more or less efficient than those of other countries such as the United States? | The British house of commons is functionally the same as the US House of representatives. There are differences, but other than the likelihood of the British getting into fist fights there is not that much different between the two. |
Special relativity says the mass of a moving body _URL_0_ has the mass of the Universe been increasing since the Big Bang? | I'm assuming you think the mass of the universe is increasing because of expansion. You can't talk about 'the universe' as an object, even taking into account relativity, because the universe is the thing that all the objects are in. The expansion of the universe is talking about the space itself expanding, so it doesn... |
how do glasses work and what my power has to do with them | In a healthy eye, the cornea and lens act to focus light onto your retina. They refract light so that it converges right at your retina, giving you a good image. In a nearsighted or farsighted eye, the calibration is off. The lens tries to get the light to converge at the retina, but it "misses", and the light converge... |
How do phones still operate when moving at high speeds? | Phones use radio waves to communicate with the cell towers. Those wave are electromagnetic waves, just like light. They move at the speed of light. Even the fastest train on the planet only moves at an incredibly tiny fraction of the speed of light. |
If trains use diesel engines as a generator to then power electric motors, why don't cargo ships do the same? | Because trains have to go on land. Trains operate at anywhere from 1mph in the yards to 60+mph out in the midwest. They have to climb up hills, go round turns, go back down hills, etc. and all this means different amounts of energy are required. Problem is, diesels - especially big ones - have one RPM where they're mos... |
Australia and video game censorship. (Or just censorship in general) | I have no idea why Australian's aren't doing anything about it but the people in charge are bitch made is all. Seriously though we didn't have a rating higher than 15+. This was mostly because we needed all states to vote yes for a new 18+ rating. Some cunt in South Australia kept voting no. |
Why does turning it off and back on help so often? | Imagine the computer is like an orchestra. If one group within the orchestra were to fall behind, and then all of the groups started getting messed up due to the un-matched group. Rather than letting that one group try to catch up on it's own by speeding up or jumping forward in the music it would be easier for the con... |
Why haven't Niagara Falls slowly eroded into a slope rather than a cliff? | I may be incredibly wrong, but this is how I remember it from GCSE geography. There's a layer of hard rock and soft rock . The hard rock doesn't erode very much, but when it reaches a cliff like that it falls down, creates constant splashing, and that splashing erodes away at the softer rock underneath. You then end up... |
Why does the human eye see more shades of green than any other color? | From a proximal biological standpoint, the answer would be that green/yellow is the part of the frequency spectrum in which we have the best frequency resolution. Look at [this graph]. You will notice that there are multiple different photoreceptor types that have some degree of sensitivity overlapping in the 'green' a... |
Politicians raise millions of dollars during their campaigns even for just the nomination. What is this money spent on and why is it so expensive? | I know a little bit about this, because my husband ran for office. Most of the money we raised went to advertising - campaign signs are expensive, mailings and postage are expensive . Some amounts went to a fundraiser we had . When the election was over, we gave small checks to two of the people who'd done a ton of wor... |
Why do restaurants peel every part of a shrimp except for the tails? | This is only done with larger shrimp, the smallest are completely de-shelled. There are a few reasons they do it this way though 1st, a lot of shrimp come that way when purchased, so if the store uses previously frozen shrimp, this is the real reason.2nd, there is some pretty icky stuff that needs to be cleaned out fro... |
What exactly produces the "Itchy" sensation? | It's a defensive reflex, like pain telling you to pull your arm away from harm. This one serves to warn you of unwanted things being on your skin that might be harmful like bugs, powders, liquids etc, thats why you can't tickle yourself. It works the same way as many other reflexes - a receptor administers the irritati... |
Why is information about Russia/Ukraine so vague? How can we not know if they are invading? | The rebels are being directly supplied/aided by Russian forces, and Russian agencies like OMON are suppressing any information gathering. That and they're violating common law of war by not clearly identifying themselves. To be honest I'm surprised that most people aren't pissed off about this. They basically just pull... |

The venezuelan protests right now. | Power vacuum after the death of chavez. people don't have money for food, and their money isn't worth much globally anyway. intense violence in the streets over the past year . a nation raised under a nationalist/socialist identity, but that has always been politically polarized. without chavez the people are trying to... |
Why will only drugs and mechanical stimulus revive a flat-lined heart, versus a defibrillator? | Defibrillators stop fibrillation, or the uncoordinated contraction of heart muscles. It doesn't start the heart beating, rather it *stops* the beating so it can resume proper timing. That makes the pumping action start working rather than just twitching. |
Why do people hiccup? And what is the hiccup itself? | A hiccup is caused by when your Diaphragm gets out of wack. "The hiccup is an involuntary action involving a reflex arc. Once triggered, the reflex causes a strong contraction of the diaphragm followed about 0.25 seconds later by closure of the vocal cords, which results in the classic "hic" sound." _URL_0_ Drink water... |
How are airsoft guns modeled after real guns without a copyright infringement? | You can't copyright a design. Copyright only covers an exact expression of a certain idea . You can trademark a design, but only if it's part of the branding of the object in a way that makes it recognizable . You could own a patents on the function of the gun, but because airsoft internals are completely differently, ... |
Can you run it . com | 1.7 Ghz is the maximum clock speed per core for your computer's CPU. The rated performance takes into account the fact that your processor is made-up of multiple cores, each of which can process data simultaneously. So the effective speed rating for your processor is probably just the actual clock rate multiplied by ho... |
The pros for marijuana legalization | In one sense, the most powerful pro for marijuana legalization is that it restores a personal freedom that the government doesn’t really have a reasonable basis for denyingMost of the arguments for Marijuana legalization center around 2 points: 1. Marijuana is less harmful and addictive than many legal drugs, such as a... |
When pepper is added to a plate of oil, why does the pepper seem to attract other pepper flakes | Have you ever seen that gravity demonstration with the big sheet and the metal ball in the middle? When you put the pepper on the oil, the surface tension holds and keeps the pepper flakes in a sort of cup. As they inevitably come closer together, they fall into each others "cups" so then the size increases, which mean... |
Why do NBA players always wait for someone to help them up? | When I played sports, it was for two reasons. To prevent injury from straining and stretching in weird positions. It was also just another aspect of playing on a team. That you were in it together, and they were there to pick you up. |
Risk Management vs Actuarial Science | Reading wikipedia, as far as I understand, Actuarial Science deals with identifying risks and assessing their severity and significance , while Risk Management deals with what strategies should be applied to the found risksActuarial science calculates the probablity of an event happening.

How come a kindle screen refreshes so slow and only in black and white, but pebble times are relatively quick and in color. | E-Paper is a generic term for a display designed to use very little or no power to retain the display of an image and do not require a backlight to be seen. There are a ton of different technologies out there that meet these somewhat vague requirements. E-Ink is the brand name of a specific type of e-paper display; an ... |
Unemployment down, Job creation up, but there are more people on welfare then ever? | Usual unemployment measures count the percentage of people _who are actively seeking or working jobs_ who don't have one. When people stop looking for jobs, they're not counted as part of unemployment figures, and this happened quite a bit during the recession. |
Why does 72 F indoors feel cold during the winter but hot during the summer? | The central areas of your house may be 72 degrees, but the outer rooms of your house are likely colder that that in the winter.

It's mentioned a lot, but how exactly does a person 'make their money' off something like oil or diamonds, do they just find it and claim it? | In countries like the United States, the government owns a lot of the uninhabited land. Someone who discovers oil on federal land can pay the government for the right to extract that oil, and then you can sell that right on to big oil companies if you like. Similarly, with mineral claims you are able to purchase land f... |
How is /r/rapingwomen still allowed? It literally contains advice on how to rape women. | Because they're not censoring content, **they are banning for harassment**. They did not ban FPH for posting images in their own sub and going "lol fatty", they banned them for going outside of the sub and even off reddit and **harassing people**. As an example, imgur started deleting their images so they started haras... |
what sort of mechanism exists in microwaves so that the tray spins in the opposite direction every time (and why)? | It's a function of cheap motors. If the microwave manufacturers spent a half-dollar more per oven on parts, it would spin the same way every time. That cuts into profits, though, so they use a motor that could spin either way on power-up, just depending on the specific way the AC is flowing when it goes hot. |
What effects would sterilization have on individuals before puberty? | Common human sterilization techniques don't affect hormone production because they don't remove any organs, you just block the "plumbing" that allows eggs/sperm to move around. It would have minimal effects on puberty and developmentIt depends on the type of sterilization.A vasectomy leaves the testes in tact and has n... |
How do teams get hats and shirts right after winning a championship? | Because they get made ahead of time. And then the ones that lose just dump them to charities and third world nationsThey do both possibilities ahead of time. The gear for the losing team is destroyed or donated to developing countries where no one has heard of March Madness. For trophies, they make two plaques, sometim... |
Why do fans cool a room when it seems like they're adding energy to the system? | It's not necessarily that the air is colder. Your body cools itself via evaporative cooling through your sweat, where the highest energy particles in the sweat are escaping the liquid and becoming gas, lowering the average kinetic energy of the remaining liquid. If the air was still, then these gas particles would rema... |
How does Karl Marx's idea of communism differ from the communism that exists today? | The thing about Marx is that he never wrote what a true communist state would look like, he died before he did. The subsequent nations that call themselves communist are based on some cherry picked ideas taken from MarxCommunism is theoretically what comes after socialism. In socialism, the working class has power, as ... |
Why is the bass in music more audible far away compared to the highs and mids? | Low pitched sounds travel farther than high pitched sounds.

How can people still live in Hiroshima and Nagasaki when they can't live in Pripyat or the Bikini Atoll? | The bombs used in Hiroshima and Nagasaki exploded in the air, so **ALOT** less radiation seeped into the environment. In Chernobyl, the worker city outside Pripyat, the disaster was a leak, followed by an explosion. This put lots of radiation into the surrounding environment. edit: Also the International Atomic Energy ... |
Why haven't we reverse engineered fish gills to make a convenient human compatible apparatus for us to breathe underwater with? | We have, but they require power and arent very good. Seen a few posts about them in the past', "I think we have but they probably couldn't compete with the cheaper alternatives, like SCUBA. |
What happens when someone takes out a massive loan (e.g. $20 million), and suddenly dies? | Assuming the loan was secured by an asset, the asset is seized like any other foreclosure. If it's an unsecured loan, the lender would sue the estate for whatever residue they can get, and write off the rest. At least in Canada, your family does NOT take on your debts when you die. If it's your spouse it's different be... |
How are potholes created and why are there more of them after snow/rain? | Temperature variance causes the pavement to form cracks, moisture from precipitation seeps into the cracks and when it freezes the cracks expand. When it thaws again the pavement breaks up and the traffic or plows remove chunks. |
If I had been born the opposite gender, would I still be "me"? | This is a purely philosophical question - we can't possibly answer it without defining what makes you you rather than someone else. We can't make that definition in any objective way."Consciousness" in the way you use it isn't really a science as much as a philosophical question. If you spend a year as a transfer stude... |
Why do so many famous actors refuse to watch their own movies? | Have you ever watched a recording of yourself? It's really unsettling. Besides, what do they care? They already know what happens in the movie since they read the script and they've already been paid. What's the point in watching it? |
Why are identical products so much more expensive in Europe than in the US? | I personally had a big grump when the XBONE pricing was announced and how it was £100 more expensive in the UK versus buying it in the US. I was ranting and raving to all who would listen, until finally someone who understood these sorts of things explained to me that it was all about tax. US states have a differing ta... |
Why do lighters have those two compartments where the liquid can flow between them instead of just one big one? | To give the lighter more structural integrity. It has nothing to do with the flame or anythingThe fuel used in lighters means that the pressure inside the fuel tank is roughly 2 atmospheres. This means that they need to make the fuel tank a bit more durable in order to be able to support the pressure. Dividing it in tw... |
How does a trail camera have such a long battery life when constantly sensing any movement, taking pictures/videos while only using a couple of AA Batteries? xpost /askReddit | They're not constantly sensing movement - they just make you think they are. Instead, the motion detection system has a peep for a tiny fraction of a second every second or so, then goes back to sleep. The peep doesn't take much power anyway, and the quiescent "snooze" state takes virtually none - some PIC systems can ... |
What is Tilt-shift photography? What makes it seem unrealistic? | Look at what is called 'macro' photography. Basically, extreme close ups. A key feature of that is narrow focal length. Focus is limited to just what is being focused on. Anything in front of, or behind it is out of focus. So if you take what is effectively a landscape photo, say a city skyline, but apply the focal eff... |
Why do people moan? | As far as moaning during sex, there's a lot of evidence that supports the theory that humans are not naturally monogamous. The shape of the penis is designed to "scrape" out competitors\' semen, for example. The female moan is thought to be an evolutionary design that attracts other males nearby to engage in sex. Kind ... |
How can margins of error be trusted? | The margin of error isn't "We know we're only possibly wrong by this much" it's "This is the known accuracy of our instrument under what we believe are operational conditions." You can still be wrongPhysics has certain ways to calculate uncertainties such as that. Let's say you 've got a ruler and you use it to measure... |
Why if light travels in straight lines does my phone produce a circular area of light on a wall | It spreads out in straight lines in the form of a cone if you view a cone from the side, you will see two divergent straight lines at the edge of the cone spreading out from your phone, when the cone hits the wall you are seeing the base of the cone which is a circle. The further away the wall the larger the circle of ... |
Why does the Reddit mobile app default a post at 46y (46 years old) while it loads? | "Unix time is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time , Thursday, 1 January 1970,[1][note 1] not counting leap seconds." _URL_0_ |
HPV is supposedly bad and needs to be cured - but I've also heard that it's not that bad and basically everyone has it. Which is it? | Both. It's very, very common infection that in some cases leads to bad health effects, including cancer. Only a small percentage of people who get HPV will develop cancer, but because so many people have it, that small percentage is still a huge number of bad health outcomes that could be avoided if everyone got vaccin... |
If the boiling point of water is 100 degrees celsius, why does water evaporate at a much lower temperature? e.g. a puddle of water | Boiling is the temperature at which a substance cannot remain a liquid and must become a gas. Evaporation is different. That's when the atmosphere absorbs some of the water. Think of it like a sponge. Unless the atmosphere has reached the point where it can't take any more moisture, it will extract water from the envir... |
How are artificial flavors created? | In many fruits, a certain type of molecule is largely responsible for its flavour and odour. These esters all share [a particular chunk] of atoms, but the atoms around that chunk in the molecule are different. For example, [here] is one of several apple flavour molecules and [here] is a pineapple flavour molecule. To m... |
How is it possible to convert light to sound? | I had to read through the thread to find the TL;DR, but /u/Qesa eventually gave it to me: > TLDR: Laser heats up carbon nanotube which rapidly cools due to its high surface area:volume ratio. This results in the CNT rapidly expanding and contracting, hence sound. So, it isn't that light is *turning into* a vibration, r... |
What was the difference between the Eastern Bloc and the USSR? | The Soviet Union was a Union of Socialist Soviet Republics. Previously independent countries came together to form a Central Governmemt while still retaining some local control, vaguely similar to how US States work. The Eastern Bloc was made up of the Soviet Union and other independent nations that were under heavy So... |
If everything in the universe is running away from each other, why is Andromeda predicted to crash into the Milky Way galaxy? | Not everything is running away from each other. This in practice happens only on a very large scale. On a local scale gravity can still bring things together. Like if you drop an apple, it will fall towards the center of the Earth, not move further from it due to expansion of space between the apple and the center of t... |
What makes it okay for one company to call itself by its brands instead of just the company name? | Unilever owns both Axe Body Spray and Dove soap.

How does x^ai (where a is any real number) actually work? | We can define x^ for arbitrary a and x by using the fact that b = e^. In this case we substitute x^ai for the value b. By the properties of logarithms, ln) = ai * ln x and so x^ = e^. So we really only need to know how e^a works to determine how x^a works for arbitrary x. This is one nice feature of exponential functio... |
Why is the Genetic Engineering ethically wrong? | Now, this one is tough, because your question holds the fallacy of "begging the question". Rather than asking "is genetic engineering ethically wrong?" you are asking *why* is it ethically wrong, which presupposes a conclusion that it is, in fact, wrong. Assuming you mean "why do people think genetic engineering is wro... |
Is it the pasta, water, or both, that need to be hot to make spaghetti? Why can't cold pasta absorb cold water? | Pasta is both dry and raw so it needs heat to cook and water to be tender. You can soak pasta in water but then it turns into dough and won't taste good |
How Wikipedia is one of the most visited sites on the internet but doesn't have a large amount of servers. | They serve mostly text, which is far smaller than images. You can download the entire Wikipedia as of November 2006, and it's only about 6-7 gigs compressed. Hell, you can carry that around on a flash drive. Also, the text is almost entirely static. There are no huge and complicated databases behind the site, tallying ... |
How does the vibrating in cell phones work? | There is a little motor that spins an unbalanced weight around in a circle, jerking the phone as it does so. |
Why do bugs and other tiny insects not break a limb or die from falling a great height. | You'd think that an ant falling from three feet is like a human falling off a skyscraper. But this isn't the case because of the square-cube law. As it relates to tiny things, the smaller something is, the more resilient it is to stresses. What the law means is that as an object's surface area increases by a power of 2... |
How Paleontologists/Historians know an object/event is 15 million years old? | Radiometric dating. ELI5 version: so let's say that a toy gets buried in the backyard alongside a piece of fruit. We can't tell just by looking at the toy, but we know how quickly a piece of fruit will get eaten by the bugs in the ground. So if we look at how much fruit is left, they can tell how long the fruit and the... |
What makes the United States' economy the most powerful in the world? Do they do anything different from other countries? | The United States is the most populous and has the most arable land of Western Countries meaning it could make good use of the technology developed over the last couple hundred years.

Why does metal taste funny? | Long story short, we don't have smell receptors for metal ions. What you are smelling is the product of stuff reacting with the metal. Edit: Metallic taste -outside of that caused by salt and other small ions that fit in the salt receptor- is not well understood. [Metallic Smell] [Metallic Taste] |
Why is only $15 a day given if selected to be on a jury? | Because no one wants to raise taxes in order to pay jurors more money. And most people would not want to pay more taxes to pay jurors more money.That fifteen dollar amount was decided a long time ago. It was a reasonable amount then, but simply hasn't been updated. Sort of how minimum wage is: back in the 70s, minimum ... |
Why do curlers sweep in front of the stones? | To smooth the ice, which affects the distance the curling stone travels, and to some degree how its path bends . |
How can you reliably recreate a person's face from DNA? | You can't. You can predict the ethnicity, and a few vague measurements. It is still difficult. That is why you see them only *sometimes*. Else crime fighting would be slightly *less difficult*. Instead looking for clues they can just look for DNA, which can give a face that can be searched easily. It is still not relia... |
Why do some people always have bags under their eyes, and what causes them to be more pronounced throughout the day? | there are two contributing factors - puffiness caused by inflammation of the skin below the eye, and thin skin/capillaries close to the surface making that area appear darker than the surrounding skin. The use of cold compresses can help mitigate this by causing the capillaries to constrict - lessening both the puffine... |
Why would anyone need a shingles vaccine? | The shingles virus IS the chicken pox virus. If you've had chicken pox, it's already inside you, HIDING and taking a nap. It could wake up some other time. Soon after exposure your immune system will knock it back out before it causes trouble. But after a while, your immune system forgets about it. The virus is hiding ... |
Every year the asphalt roads get torn up, then patched/re-paved. Hasn't road tech/asphalt tech improved to the point where this doesn't need to happen year after year? | They can build roads to a standard right now that will last much longer, but it would cost a lot more per mile and the job goes to the lowest bidder. They build roads to much higher standards in most of Europe and they last a lot longer.Road *technology* has improved, but the incentives haven't. In parts of northern Eu... |
How come there's always spam comments on sites like Youtube and Yahoo but not on Reddit. | Also spam in a youtube comment is seen for a long time by a lot of people . Reddit posts go stale very quickly. Most popular reddit subs have so many new posts every hour, that a spam comment quickly gets buried with new legitimate postsBecause reddit has a spam filter, and mods clean up what gets through. You also nee... |
Why is r/gonewild more popular than some other subreddits of the same genre? | Same reason Facebook is more popular than Google+. Subs like that need a userbase in order to attract users. As the most famous one, it attracts the most new users. It's popular because it's popular. |
Why were Jews granted a state (Israel) by the UN but not the Kurds? | They got it as a compensation for Holocaust. International Jewry is powerful, so they lobbied for their state ever since the British got Palestine from the Ottomans in 1919. And after the WW2 they finally succeeded. Kurds are never going to achieve what Israel did, because a) they have no lobbying power and b) Turkey w... |
