where does all the food go?	Poop, heat, and consumed useful energy. You basically take the nutrients, break them down, make energy molecules, release a lot of heat along the way. Then, use this energy to build things like proteins from things you got from food (amino acids). If you're not gaining weight despite eating insane amounts, you either h...	[ "Wherever food is harvested, manufactured or distributed there is a need for containers to enable the food to travel securely and in good condition to the shop, warehouse or distribution depot. For many foods, especially those in their own individual containers such as canned vegetables, the common container is the...
if cellular radio waves are basically everywhere all the time, how do they not get blended with eachother?	They all have slightly different frequencies, which makes it easier to tell the difference. Imagine you're trying to pull one thing out of a box while blindfolded. There are three items in the box. Those three things are all apples, but you're trying to get a Granny Smith. The different frequencies would be like takin...	[ "The increased capacity in a cellular network, compared with a network with a single transmitter, comes from the mobile communication switching system developed by Amos Joel of Bell Labs that permitted multiple callers in a given area to use the same frequency by switching calls to the nearest available cellular to...
How does Antivirus software work?	While there are many different styles of viruses and attacks, a lot of antivirus software deployed relies on a currently known threats or vulnerabilities. It is hard to defend against an unknown vector of attack (I use virus here generically), but some basic attacks/detections are as follows: Size An easy way to ...	[ "Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect users from: malicious brow...
how did we come to understand universal symbols for play, rewind, fast forward, and so on. what is the design of these symbols called?	[No one is really sure](_URL_0_), but the pause icon resembles the symbol for a break in electronic schematics, and the play symbol seems to imply forward motion.	[ "has a long history that goes back to Gottfried Wilhelm Leibniz. The mathematician Louis François Antoine Arbogast was one of the first to manipulate these symbols independently of the function to which they were applied.\n", "The main symbols date back to the 1960s, with the Pause symbol having reportedly been i...
what is bicarbonate?	Bicarbonate is HCO3(-). It acts as a buffer keeping your blood within certain pH values. It is formed when H2O and CO2 are combined in red bllod cells by carbonic anhydrase(an enzyme) to make carbonic acid, H2CO3. This carbonic acid quickly breaks down into H and HCO3. When it reaches the lungs the bicarbonate is se...	[ "The term \"bicarbonate\" was coined in 1814 by the English chemist William Hyde Wollaston. The prefix \"bi\" in \"bicarbonate\" comes from an outdated naming system and is based on the observation that there is twice as much carbonate () per sodium ion in sodium bicarbonate (NaHCO) and other bicarbonates than in s...
When did Sunzi's "The Art of War" become popular in the West?	It's a late 20th century phenomenon. The book was not translated into any European language until French in the late 18th century and wasn't completely translated into English until 1910 by Lionel Giles (as _Sun Tzu on the Art of War_). Machiavelli was certainly unaware of it. Also, the Chinese characters "兵法" are more...	[ "West became known for his large scale history paintings, which use expressive figures, colours and compositional schemes to help the spectator to identify with the scene represented. West called this \"epic representation\". His 1778 work \"The Battle of the Boyne\" portrayed William of Orange's victory at the Bat...
During WWII, what was Stalin's plans for if the Germany army captured Moscow?	In October 1941 the Soviets began seriously discussing the possibility of Moscow falling. Stalin decided that he was going to stay in the capital. It was feared that seeing Josef Stalin and the government flee would cause a massive panic among the cities massive population. There was also an idea of burning Moscow simi...	[ "Correctly calculating that Hitler would direct efforts to capture Moscow, Stalin concentrated his forces to defend the city, including numerous divisions transferred from Soviet eastern sectors after he determined that Japan would not attempt an attack in those areas. By December, Hitler's troops had advanced to w...
If I were a sexually active gay man in early 19th century England that never actually broke the anti-sodomy laws how open could I be?	This question got me curious: what does it mean to be sexual active but not violate the anti-sodomy laws on the books? The following answer is not from a deep font of knowledge, but is merely what I have gathered through my own curiosity this evening. Throughout the 19th century there were three acts that outlawed "b...	[ "Homosexual acts between males were illegal in England and Wales until the 1967 Sexual Offences Act, which implemented the recommendations of the Wolfenden report published a decade earlier. The fact that willing participants in consensual homosexual acts could be prosecuted made them vulnerable to entrapment, and ...
what happens to prices/wages when a country implements euro as the currency?	See where the money and the people are going. Say you run your country with your own currency. You get to set interest rates, and if your country slows down, you can lend money at a cheaper rate. The downside is that your currency may be cheap today and dear tomorrow, and people in other countries may not want to do...	[ "Another effect of the common European currency is that differences in prices—in particular in price levels—should decrease because of the law of one price. Differences in prices can trigger arbitrage, i.e., speculative trade in a commodity across borders purely to exploit the price differential. Therefore, prices ...
Why do war memorials in Britain commemorate World War I as 1914 to 1919	World War I technically ended in 1919. Germany signed an armistice with the Allies in November 1918 which marked only the end of actual fighting, but not the war itself. The war is considered still ongoing until the terms of surrender are formalized and signed. That occurred in 1919 during the Paris Peace Conference w...	[ "War memorials in England take a wide variety of forms and commemorate centuries of conflicts, though memorials to conflicts and the soldiers who fought in them—rather than exclusively commemorating victorious commanders—only started to be commonplace after the Battle of Waterloo in 1815, which ended the Napoleonic...
how can an animal eat its own kind with no side effects but human cannibalism causes brain damage?	It isn't the human flesh that causes brain damage, it is the risk of parasites/prions in the human flesh. Thoroughly cooked human flesh won't hurt you, but if it is under cooked or you eat infected brain matter (as with the cows who got mad-cow disease) then you are at risk. Generally you only find cannibalism in les...	[ "Cannibalism may become apparent when direct competition for limited resources forces individuals to use other conspecific individuals as an additional resource to maintain their metabolic rates. Hunger drives individuals to increase their foraging rates, which in turn decreases their attack threshold and tolerance...
What decides which plate subducts in ocean-ocean convergent plate boundaries?	For the ocean-ocean case, basically the age of the plates. Age is essentially a proxy for temperature/thickness. Imagine tracking a piece of oceanic crust from its formation point at a mid-ocean ridge. As it moves away from the ridge, it cools and thickens, increasing the aggregate density of the plate at that point (o...	[ "BULLET::::2. \"Divergent boundaries (Constructive)\" occur where two plates slide apart from each other. At zones of ocean-to-ocean rifting, divergent boundaries form by seafloor spreading, allowing for the formation of new ocean basin. As the ocean plate splits, the ridge forms at the spreading center, the ocean ...
why are people born with photographic memories? how does this impact psychological childhood development?	Photographic memory is a myth. Not a single case of it has even been found, so no one is born with it. Makes for great TV though. There is such a thing as Eidetic memory, but only really found in children, disappears as they get older, and even this is often warped or flawed in some ways. There is no such thing...	[ "BULLET::::- There is no scientific evidence for the existence of \"photographic\" memory in adults (the ability to remember images with so high a precision as to mimic a camera), but some young children have eidetic memory. Many people have claimed to have a photographic memory, but those people have been shown to...
Speed differences for loading content from Discs, Hard-Drives and Solid State Drives(SSD)	It might load quicker from an HDD/SDD. I'm not sure about PS1 emulators but some emulators (sometimes only on some roms) need to slow down reading from HDDs to match the loading speed of the original drive as loading at a higher speed can throw off the game timing and cause glitchs or crashes. This can even happen w...	[ "In modern computers, hard disk drives (HDDs) or solid-state drives (SSDs) are usually used as secondary storage. The access time per byte for HDDs or SSDs is typically measured in milliseconds (one thousandth seconds), while the access time per byte for primary storage is measured in nanoseconds (one billionth sec...
how were the first construction cranes built when there were no other cranes to reach or lift the heavy weights?	We've had simple cranes being built thousands of years in the past, so putting together a small crane isn't an insurmountable task. Besides, you don't necessarily need a crane to put together another crane, as long as you've got something like a ledge to work with, or even a pulley system mounted to a higher point, lik...	[ "A crane for lifting heavy loads was developed by the Ancient Greeks in the late 6th century BC. The archaeological record shows that no later than c. 515 BC distinctive cuttings for both lifting tongs and lewis irons begin to appear on stone blocks of Greek temples. Since these holes point at the use of a lifting ...
how it is determined that people who died while texting-and-driving were actually looking at their phone at the time of (or time leading to) impact?	If the deploying airbag embeds the phone into the drivers cranium, then that’s a good indicator too.	[ "A 2014 report from the National Safety Council, which compiles data on injuries and fatalities from 2013 and earlier, concluded that use of mobile phones caused 26% of U.S. car accidents. Just 5% of mobile phone-related accidents in the U.S. involved texting: \"The majority of the accidents involve drivers distrac...
Did the ancient Arabs, such as the Qedarites, self-identify with the Biblical genealogy of the Arabs, i.e. Ishmaelites?	> Is there any evidence of the ancient Arabs calling themselves Ishmaelites? The term Ishmaelites appears mostly in non-Arabic sources. While a genealogical link between the Arabs and Ishmael appears in numerous Arabic sources, Arabs nonetheless did not use that term (the Arabic equivalent of the term, *Ishmaelite...	[ "The oldest surviving indication of an Arab national identity is an inscription made in an archaic form of Arabic in 328 using the Nabataean alphabet, which refers to Imru' al-Qays ibn 'Amr as \"King of all the Arabs\". Herodotus refers to the Arabs in the Sinai, southern Palestine, and the frankincense region (Sou...
how does my hair get tangled so quickly?	Entropy. There are more ways for your hair to be tangled, than untangled.	[ "The hair is divided at the back in two uniform strands, slicked and laid in opposite directions around the head. On one side of the head, usually in the temporal region, the two strands are individually tightened in the same direction. The two strands are then twisted, whereby the rotation of the two individual st...
why do i look up and the right when i'm trying to remember something?	I look to the side, personally; I think looking in another direction helps you focus on something different quicker.	[ "Eye movement to the left or right for many people seems to indicate if a memory was recalled or constructed. Thus remembering an actual image (V) is associated more with up-left, whilst imagining one's dream home (V) tends (again not universally) to be more associated with up-right.\n", "In situations where one'...
It was common for upper-class European women prior to the contemporary era to occupy themselves with pursuits in music and art as a matter of enriching home-life. Do we know of any outstanding talents among them?	> there had to be some that were truly gifted? Certainly. Amy Marcy Cheney Beach (1867-1944) was a composer and pianist. She was born into a very well doing family, a child prodigy who started composing at around 5 and started giving recitals at 8. She had formal musical instruction for a while, but was mostly...	[ "There was increased participation of women in music-making in the eighteenth century. It is known that French women undertook music instruction at a young age, under the guidance of a music master before marriage and family responsibilities intervened. Many women involved in music were noblewomen or were from fami...
how do scientists determine how much water you need to drink?	IIRC, the "recommended amount" of water per day has no real health benefits. Maybe a myth, may be a misconception.	[ "From the data and observation, the best water for drinking is the water from a nearby river. However, further data must be collected over a longer period of time. Also, bacterial and microbial tests need to be completed.\n", "An accurate method for determining the amount of water is the Karl Fischer titration, d...
Why are there so many species of birds compared to other tetrapod vertebrates?	So this is neat because birds are also the phylogenetically youngest of the tetrapods. The big reason is that birds, by virtue of flying, opened up a mostly unexploited niche (habitat) space that they could fill without competition. They could then partition this new habitat leading to speciation (in a process very s...	[ "Birds generally have lower EQ than mammals, but parrots and particularly the corvids show remarkable complex behaviour and high learning ability. Their brains are at the high end of the bird spectrum, but low compared to mammals. Bird cell size is on the other hand generally smaller than that of mammals, which may...
Have humans always had to brush their teeth to avoid rotting?	The short answer is that no, brushing of the teeth wasn't necessary. Humans didn't live nearly as long until recently, and there was no reason to evolve more long-lasting teeth. The long answer is that there is no selective pressure to produce teeth that last longer. Teeth don't usually start getting seriously rotten ...	[ "Dental decay is however easily prevented by reducing acid demineralisation caused by the remaining dental plaque left on teeth after brushing. Risk factors for tooth decay include physical, biological, environmental, behavioural, and lifestyle-related factors such as high numbers of cariogenic bacteria, inadequate...
How did the Gauls manage to muster so many men during the Gallic War?	So I'm assuming you mean the Gallic Wars that occured during the Roman Republic involving Caesar's conquest. The Romans did have better organization, but did not, many times have larger armies than the medieval world. The average legion was about 6,000 men, and a large Roman army composed maybe 3 of them at the most d...	[ "Though the Gallic tribes were just as strong as the Romans militarily, the internal division among the Gauls guaranteed an easy victory for Caesar. Vercingetorix's attempt in 52 BC to unite them against Roman invasion came too late. He proved an astute commander, defeating Caesar in several engagements, but Caesar...
why do we have summer and winter time? wouldn't it be easier to shift the clock half an hour in one direction and leave it that way all year?	It started as a way to help farm families manage work and school time. It stuck because it saves many millions of dollars in energy each year. Reduces stress on the power grid and other benifits. Adjusting humans can be done, the sun just is so set in its ways.	[ "Winter time is the practice of shifting the clock back (compared to the standard time) during winter months, usually −1 hour. It is a form of daylight saving time which is the opposite compensation to the summer time (+1, +2). However, while summer time is widely applied, use of winter time has been and is very ra...
Could planets survive the heat death of the universe? Or Would they degrade also.	If the planets are far enough from their stars when they die, so as not to get caught in a supernova or planetary nebula, the planets would be stable for arbitrarily long times. They'd get really cold though.	[ "If Earth is not destroyed by the expanding red giant Sun in 7.6 billion years, then on a time scale of 10 (10 quintillion) years the remaining planets in the Solar System will be ejected from the system by violent relaxation. If this does not occur to the Earth, the ultimate fate of the planet will be that it coll...
why is it conservative media in the us usually stands against minorities in alleged police brutality cases?	I think you'd have to provide some specific evidence here. Most of the stuff I've seen is them pointing out in the Michael Brown case that the rest of the media was really quick to label him a blameless victim and pointing out all of the contrary evidence.	[ "Racial inequalities is a major factor that has contributed to forming an anti-police sentiment. As such, the history of law enforcement's employment of coercive measures that have led to instances of police brutality involving underprivileged communities is paramount to our \"understanding of the substantial race ...
why we think pirates talk the way they do	_URL_0_ Number 6.	[ "Pirate has multiple meanings in sexual slang. Several of them emerged in the 20th century and play off the tradition that pirates took whatever they wanted, including sex, which was \"seen as a conquest.\"\n", "As academics like Peter Leeson and Marcus Rediker argue, a pirate was more often than not someone from...
what is math and why does it work?	One of the problems I see with a lot of the explanations here is that they are focused strictly on one type of mathematics. Mathematics is a large topic that encompasses many parts. As such I share the definition that I share with my students: Borrowed from "The Language of Mathematics: Making The invisible Visible" ...	[ "Mathematics (from Greek μάθημα \"máthēma\", \"knowledge, study, learning\") includes the study of such topics as quantity (number theory), structure (algebra), space (geometry), and change (mathematical analysis). It has no generally accepted definition.\n", "Mathematics is essential in the formation of hypothes...
birth control statistics (nsfw)	The birth control failure rates you usually see quoted are derived by what's called the Pearl Index if you want to look up more details.

how are secret formulas legal?	There are certain ingredients which are banned, and that can not be used in any capacity. Since the creation, importation, transportation, and use of these ingredients are strictly regulated, there is little fear that they are going to end up in consumer products, especially major ones that many people use. So the gov...	[ "A key use of formulas is in propositional logic and predicate logic such as first-order logic. In those contexts, a formula is a string of symbols φ for which it makes sense to ask \"is φ true?\", once any free variables in φ have been instantiated. In formal logic, proofs can be represented by sequences of formul...
how does augmented reality graffiti work??	Augmented reality is a catchall term for the use of computer graphics overlaid on our view of the real world. A live video stream can be edited to include artificial elements, or people might look through a clear screen that displays such things to the viewer. In practice this can be a symbol such as a QR code which a ...

Does any plant grow fast enough to be able to see the plant grow?	As I understand it, if you were very very patient, yes you could perceive the growth of some of those bamboo. I don't know of any other plant that grows that fast. Some algae might be able to in the right conditions.	[ "The growth rate of plants is extremely variable. Some mosses grow less than 0.001 millimeters per hour (mm/h), while most trees grow 0.025-0.250 mm/h. Some climbing species, such as kudzu, which do not need to produce thick supportive tissue, may grow up to 12.5 mm/h.\n", "Plants can grow as much as 50 percent f...

Some of those packets direct a device to send some packets in reply.\n", "During USB communication, data is transmitted as packets. Initially, all packets ...
how does adding spin to a bullet using rifling make the gun more accurate?	It is conservation of momentum, in this case rotational momentum. One of the major problems with early ammunition was that it tended to tumble unpredictably and this would interact with the drag of the air to move them off target. A rotating bullet though tends to want to keep rotating which means that changing where i...	[ "Despite differences in form, the common goal of rifling is to deliver the projectile accurately to the target. In addition to imparting the spin to the bullet, the barrel must hold the projectile securely and concentrically as it travels down the barrel. This requires that the rifling meet a number of tasks:\n", ...
why do central banks use interest rates as the primary tool for adjusting the supply of money?	Because interest rates also let you adjust the supply of money 'down' too. Central banks do have other ways to add money to the economy beyond interest rates. One of the most common is to buy/sell bonds. If the central bank buys bonds then they basically inject money into the banks, and the reduction in supply also ...	[ "Central banks implement policy primarily through controlling short-term interest rates. The money supply then adapts to the changes in demand for reserves and credit caused by the interest rate change. The supply curve shifts to the right when financial intermediaries issue new substitutes for money, reacting to p...
why isn't chicken meat marbled?	Actually if you have a corn fed chicken that us free range is has a small degree of marbling however because the fat is translucent and thin it nearly always acts like a baste for the bird (which is why many chickens when roasted tend to leech do much fat)	[ "Roast chicken is chicken prepared as food by roasting whether in a home kitchen, over a fire, or with a professional rotisserie (rotary spit). Generally, the chicken is roasted with its own fat and juices by circulating the meat during roasting, and therefore, are usually cooked exposed to fire or heat with some t...
why can't digital clocks retain the time when unplugged/powered down if phones and computers can?	Digital clocks tend not to have backup batteries, though some do and can keep time across power outages.

who decided that the standards were 4:3 16:9 21:9 for aspect ratio?	It's because 4:3 is closest to our vision and is best to relay information, 21:9 was already the standard of cinema and is best to describe scenery. 16:9 is just the compromise between those two. And for where those numbers came from, there's only 1 word: compromise. The artist, engineers, and the market all fought w...

Could sign language take root and persist in wild chimpanzees without continued human contact?	I was interested in this idea, and asked a primatologist who had studied chimp behavior about it. She seemed to think it was relatively unlikely. Apparently chimps very rarely sign at each other, and the chain of behavioral mimicking is kind of one sided and dependent on social status. They also apparently don't ten...

From this perspective, an alteration in the intensity of light would induce changes in the kinetic energy of the electrons emitted from the metal. Furthermore, accordin...
I heard someone say recently that Rome destroyed themselves because of moral decay and fiscal irresponsibility. This didn't sound right to me, and I wanted to hear what /r/AskHistorians had to say about it.	That was Gibbon, or a fan of Gibbon? We'll have to start by defining "the fall of Rome." 410 CE, when it was sacked? 476, when the last Roman emperor abdicated? 1453, with the fall of Constantinople?
