do caterpillars turn into liquid and then reform into a butterfly in the cocoon? or do they keep some of the same parts?	<p> to begin the pupal or chrysalis stage, the caterpillar attaches itself with a silk pad and hangs upside down on a leaf. about 24 hours later, its skin splits, exposing a dull, bronze-coloured case known as the pupa or chrysalis. the pupa hangs for about a week without movement. within the pupa, the caterpillar is t...	Here's an interesting podcast about that very thing: The upshot is that yes, they turn into goo. But also, it's been proven that memories persist through the goo stage. So somehow, something carries through the chrysalis. It seems like there may be more to memory than we currently understand.
why is it on clear nights it is much cooler then on cloudy ones?	<p> because of its temperature, the atmosphere emits infrared radiation. for example, on clear nights earth's surface cools down faster than on cloudy nights. this is because clouds (ho) are strong absorbers and emitters of infrared radiation. this is also why it becomes colder at night at higher elevations. <p> much ...	Clouds act like insulation and trap heat, but it's not uncommon for temps to change day to day for other reasons...
how is sound quality increased?	<p> perceived quality can be influenced by listening environment (ambient noise), listener attention, and listener training and in most cases by listener audio equipment (such as sound cards, speakers and headphones). furthermore, sufficient quality may be achieved by a lesser quality setting for lectures and human spe...	Here's the analogy - a computer understands data as straight lines - a square is 4 straight lines at 90 degree angles. An octagon is 8 straight lines at 135 degree angles, etc. Sound is like a circle. In order to understand it, the computer has to turn it into a shape made of straight lines. Software encoding and bit r...
what stops a rocket in space from accelerating to a really high speed when there is no air in space which could lead to drag?	<p> drag is a force opposite to the direction of the rocket's motion relative to any air it is moving through. this slows the speed of the vehicle and produces structural loads. the deceleration forces for fast-moving rockets are calculated using the drag equation. <p> a related issue is drag. if the near light-speed ...	Theoretically, nothing stops the rocket from accelerating. Practically, you need energy (in the form of rocket fuel, for example) to accelerate. To gain a really high speed, you need a lot of rocket fuel.
why do some things seem to cause heartburn within minutes, while some things need to digest before causing heartburn like an hour later?	<p> heartburn is usually due to regurgitation of gastric acid (gastric reflux) into the esophagus and is the major symptom of gastroesophageal reflux disease (gerd). in about 0.6% of cases it is a symptom of ischemic heart disease. <p> heartburn can be caused by several conditions and a preliminary diagnosis of gerd i...	Heart burn occurs due to reflux of stomach acids back into the esophagus , and this occurs due to a not so tight lower esphageal sphincter (junction between your esophagus and stomach ) Normally it's tight and closed and only opens up when food reaches it but a lot things could affect it. Heavy meals require more acid ...
what is preventing terrorists from using nuclear weapons?	<p> while no terrorist group has ever successfully acquired and used a nuclear weapon, many political scientists and prominent government officials consider nuclear terrorism to be one of the single greatest threats in global security. there is strong evidence that terrorist groups like al-qaeda are actively seeking to...	Having access to the right materials, and enough of it to do significant damage. Also it takes money to build the proper facilities to do it. You also need educated and skilled people to run the facility and make the bomb. The things needed to do this is heavily regulated by the UN. Plus intelligence agencies keep eyes...
image sizes. if the camera settings stays the same and the image is stored as a set of pixel values, why does the image size change?	<p> on 2d displays, such as computer monitors and tvs, the display size (or viewable image size or vis) is the physical size of the area where pictures and videos are displayed. the size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. it...	It has to do with the way image compression works. If you have an image with large uniform areas, like a blue cloudless sky, compression is going to be a lot more efficient than with an image with a lot of detail. Let's just assume you have 200 blue pixels in a row as opposed to a mix of blue and white in a cloudy sky,...
why do some bands hide their drum set behind glass during live shows, like garbage or the who, but most bands do not?	<p> drummers often bring a carpet, mats or rugs to venues to prevent the bass drum and hi-hat stand from "crawling" (moving away) on a slippery surface from the drum head striking the bass drum. the carpet also reduces short reverberation (which is generally but not always an advantage), and helps to prevent damage to ...	It's been many years since the rocker days of my youth, but if I remember correctly, it has to do with better mic control for the drums, and less bleed over to the other mics on stage. Basically, drums are noisy AF and you want to have as much control of that as possible as part of the total mix. If to much of the drum...
how can the iranian nuclear program be "limited" in such a way that reactor grade uranium can be produced but weapons grade cannot?	<p> a nuclear weapon primary stage using uranium uses heu enriched to ~90% u, though the secondary stage often uses lower enrichments. nuclear reactors with water moderator require at least some enrichment of u. nuclear reactors with heavy water or graphite moderation can operate with natural uranium, eliminating altog...	Honestly, there's nothing really stopping the iranians from trying to make weapons grade uranium. However, the israelis have taken many actions against Iran's nuclear program including killing Iran's scientists and destroying their centrifuges.
how does antivirus software get created?	<p> 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 brows...	> antivirus companies like McAffee and Symantec track and effectively create software to combat They don't. More seriously though... AV vendors use a handful of tricks to try to detect and combat malicious software. nothing is perfect, though, they just do their best. Some common techniques: 1. blacklists - this is...
how come your hearing is better when you have been in silence for a while?	<p> bullet::::- severe hearing loss - people with severe hearing loss depend on powerful hearing aid. however, they often rely on lip-reading even when they are using hearing aids. the most quiet sounds heard by people with severe hearing loss with their better ear are between 70 and 95 db hl. <p> bullet::::- mild hea...	Your hearing isn't better, so much as your concious mind is focuses much more on individual sounds. Our brains naturally tune out a lot of stimuli, especially if it's repetitive, to minimize neural load and energy usage. Being in a silent space for awhile causes our brains to focus much more on sound in order to listen...
mixers	<p> a mixer (mixing console, mixing desk, mixing board, or software mixer) is the operational heart of the mixing process. mixers offer a multitude of inputs, each fed by a track from a multitrack recorder. mixers typically have 2 main outputs (in the case of two-channel stereo mixing) or 8 (in the case of surround). ...	A mixer by itself only routes selected signals to an output. By moving the faders for the various inputs on its controls, all you're doing is opening and closing electrical connections to the mixer's various outputs. The EQ controls (e.g. high, mid, low) route the signal through various transistors, resistors and capac...
what would happen to the earth if all the whales were gone?	<p> although the whales no longer face pressure from commercial whaling, mankind remains by far the greatest threat to these species: the two leading causes of death are being struck by ships and entanglement in fishing gear. ingestion of plastic marine debris also presents a growing threat. for the north atlantic righ...	ELI5 does not allow hypotheticals. Questions like this are better in r/asksciencediscussion.
why fine-grained sand doesn’t come off from your feet even when they’re already dry?	<p> sand grains will always stick together unless the sand is reasonably fine. while dry sand is loose, wet sand is adherent if the proper amounts of sand and water are used in the mixture. the reason for this is that water forms little "bridges" between the grains of sand when it is damp due to the forces of surface t...	The attractive force between grains of sand and the things they stick to is related to the area of contact, and the mass is related to the volume. Small particles have a larger ratio of surface area to volume than larger particles. If we consider each grain as a sphere, the surface area is A = 4 pi r^2 And the volume i...
elis: why are we so fascinated with scandinavian countries?	<p> in the book, sanandaji argues that particularly the left has long praised scandinavian countries for their high levels of welfare provision and admirable societal outcomes. although true that scandinavian countries are successful, the author makes the case that this success pre-dates the welfare state. according to...	Because economically, politically, and socially... many of them are the best humanity has provided. Mostly stable economies, education, and lack of crime. Not everyone agrees with that of course, but one must admit they ams gots a real sweets gigs.
how was france chosen for a spot on the u.n. security council as a veto-wielding member?	<p> france uses its veto power sparingly. the last time it unilaterally vetoed a draft was in 1976 to block a resolution on the question of the independence of the comoros, which was done to keep the island of mayotte as a french overseas community. it also vetoed, along with u.k, a resolution calling on the immediate ...	It was one of the surviving non-Axis great powers at the end of the war. Whatever one might think of France, from the perspective of a person living in 1945 with a knowledge of history, leaving France out would have seemed much less odd a concept than the inclusion of China probably was. Brazil was a minor power. India...
what exactly does it mean to "mine" a bitcoin?	<p> a bitcoin is defined by a sequence of digitally signed transactions that began with the bitcoin's creation, as a block reward. the owner of a bitcoin transfers it by digitally signing it over to the next owner using a bitcoin transaction, much like endorsing a traditional bank check. a payee can examine each previo...	Mining bitcoins is like searching for prime numbers. It takes a long time to find prime numbers, but if you find one, it's very easy for others to confirm that it is one. If I told you to search for prime numbers greater than 1000, it would take some computation time to do trial-But and-error, but if I told you 1009 wa...
what is the internal dialogue in your head?	<p> studies have revealed the differences in neural activations of inner dialogues versus those of monologues. functional mri imaging studies have shown that monologic internal speech involves the activation of the superior temporal gyrus and the left inferior frontal gyrus, which is the standard language system that i...	I strongly recommend the book Incognito by David Eagleman, which is a bit heavy for a 5 year old. He goes into it pretty well, but to summarize in ELI5 manner: The brain is more complicated than a computer, because it is made of several competing systems. There isn't just one way that you make a decision. For example...
why are some betting odds written in the simplest form (like 2/1) and some not fully simplified (like 4/6)?	<p> bullet::::- the odds are defined as the ratio of the number of ways "not" to draw the hand, to the number of ways to draw it. for instance, with a royal flush, there are 4 ways to draw one, and 2,598,956 ways to draw something else (2,598,960 - 4), so the odds against drawing a royal flush are 2,598,956 : 4, or 649...	Comparative purposes. Fractional betting odds (as opposed to decimals or moneyline) commonly use a single denominator which isn't the lowest, but is consistent across a table. Say there's 4 horses in a race, you might see a spread of odds like this : 4/6, 4/2, 4/12, 4/3 Sure, you could write it as: 2/3, 2/1, 1/3, 4/3, ...
why the uk never made their overseas islands integral part of their country?	<p> the british overseas territories (bots) or united kingdom overseas territories (ukots) are 14 territories under the jurisdiction and sovereignty of the united kingdom. they are remnants of the british empire that have not been granted independence or have voted to remain british territories. these territories do no...	In this case France is the odd man out. Most countries with oversea territories have different level of citizenship, different set of laws and different tax rules. There is some sort of superiority and ownership over these territories that is not part of the country but rather owned by the country. In the same way that...
why do periodicals have dates far into the future?	<p> the dates given on the title pages are often considerably earlier than the actual publication date. for example, book 8, volume i ("histoire naturelle") of the first edition has 1809 on the title page, but its accepted publication date is 1826. the geographical volume (which contains maps) was not printed before 18...	Periodicals arent published daily, most are monthly or weekly, so the date you see is intended to be the date it is on news stands, so in that case, you will see that same issue of Us magazine available on news stands until July 8th, at which point a new issue with a new date is on it.
if jeff bezos looses half of his money upon divorce, why is he worth all of the money when he is married?	<p> rimes sought unspecified damages because her attorney was not sure of how much money had been lost in the preceding five years. according to rimes' lawyer, her mother hired two accountants to investigate how much was taken from rimes' fortune, and it was estimated that the men acquired around eight million dollars ...	Because the money is his. If Jeff went into the bank while married he can take out every penny, but when they get divorced he loses whatever amount he ends up losing, giving it to his wife.
eli17: what's so great about "the great gatsby"?	<p> gatsby has recently been read as a personification and representation of human-caused climate change, as "gatsby’s life depends on many human-centered, selfish endeavors" which are "in some part responsible for earth’s current ecological crisis." <p> postmodern criticism of gatsby seeks to place the novel and its ...	The reason its great is because of Jay Gatsby. All the people around him are shallow and materialistic. Jay is the last American dreamer. Fitzgerald sees the 20's as a time when morals were decaying. The people who attend Jay's parties are social climbers. They have an insatiable desire for wealth and pleasure; they're...
the keto diet	<p> the ketogenic diet is a diet high in fat en low in protein and carbohydrates, with up to 90% of calories obtained from fat. since the diet is low in carbohydrates, the body gets little glucose, normally the main energy source. the fat in the diet is converted by the liver in ketone bodies, which causes a build up o...	In a normal diet, where people eat a lot of carbohydrates ("carbs)," your body takes those carbs and turns them into glucose, which is basically sugar. Using all of that sugar for energy can be great, but it isn't the only way the body can get energy. Your body can also get energy from fat. Instead of turning fat into ...

What's your favorite food? You can't eat it. You can't eat any of the foods you 5-year-olds like. That means no pizza, no french fries, no chicken nuggets, no soda, no juice, no pancakes, no waffles, no froot loops, no lucky charms, no pumpkin pie, no apple pie, no apples, no bananas, no banana bread, no bread, no sand...
why don't downloaded games, burnt to dvds work on the xbox 360 etc?	<p> compared to physically distributed games, digital games like those offered on the steam digital distribution service cannot be lost or destroyed, and can be redownloaded at any time. services like steam, origin, and xbox live do not offer ways to sell used games once they are no longer desired, even though some ser...	Xbox games have a special key and protection mechanism burnt onto the discs that only the xbox disc drive can unlock. A random burnt dvd will not pass this test. ELI5: Xbox does a handshake with the disc before it will load a game.
why do companies include sneaky extra offers in software installations?	<p> download valley is a cluster of software companies in israel, producing and delivering adware to be installed alongside downloads of other software. the primary purpose is to monetize shareware and downloads. these software items are commonly browser toolbars, adware, browser hijackers, spyware, and malware. anothe...	If you are referring to things like new toolbars, 'security scans' and the like, it's because they get paid to include them in their installation packages by the companies that produce the extra software.
why does congress have the power to redraw their congressional districts?	<p> congressional redistricting occurs every 10 years as congressional boundaries are redrawn after the census. under article one of the constitution, the state legislature controls this process. in order to prevent gerrymandering, the proposed legislation would require states to use independent commissions to design t...	Gerrymandering always occurs. Due to the perceived issues associated with gerrymandering and its impact on competitive elections and democratic accountability, numerous countries have enacted reforms making the practice either more difficult or less effective. Countries such as the U.K., Australia, Canada and most of t...
if a human was born, raised, and lived in space their entire life, how would zero gravity effect their skin, organs, bones, and body?	<p> artificial gravity has been suggested as a solution to the various health risks associated with spaceflight. in 1964, the soviet space program believed that a human could not survive more than 14 days in space due to a fear that the heart and blood vessels would be unable to adapt to the weightless conditions. this...	Truthfully, we don't really know, that is part of the mission of the International Space Station. To monitor the effects long periods of weightlessness have on the human body.
why does a phones signal interfere with landing and take off of aircraft?	<p> mobile phone use on aircraft is starting to be allowed with several airlines already offering the ability to use phones during flights. mobile phone use during flights used to be prohibited and many airlines still claim in their in-plane announcements that this prohibition is due to possible interference with aircr...	If you have a phone that does not meet the regulations for electromagnetic emissions, there is a fault with the airplanes avionics, there is a slight possibility that your phone might have a slight impact on one of the several redundant systems the pilots use to navigate. In other words they don't. The primary reason y...
how does swearing an oath not to lie in court help during the trial?	<p> in a courtroom, jurors and witnesses are required to swear an oath before partaking in a trial. this involves the individual raising his or her right hand, often placing the other hand on an object of ceremonial importance, such as the bible, and vowing, as a juror, that he or she will give a “true” verdict based o...	The prosecution would be an idiot to ask that question. Because you can use the 5th amendment and not answer. You cannot lie. You also cannot be compelled to incriminate yourself.
does surround sound work with cochlear implants?	<p> some virtual surround systems work by directing a strong beam of sound to reflect off the walls of a room so that the listener hears the reflection at a higher level than the sound directly from the loudspeaker. one example of this technology is a commercially available "digital sound projector" by cambridge mechat...	Surround sound would only work with bilateral cochlear implants, which are less common than unilateral. They are mostly used with infants and young children whose auditory and language centers are still developing. Bilateral implants could, in theory, detect surround sound, but the sound quality of implants is still pr...
how does a ship made of steel float?	<p> a ship will float even though it may be made of steel (which is much denser than water), because it encloses a volume of air (which is much less dense than water), and the resulting shape has an average density less than that of the water. <p> in a typical modern steel ship, the hull will have watertight decks, an...	The shape. Shape it like a bowl, so that it displaces the water, and any material will float - concrete, lead, whatever. Shape the same material into a sphere, and it will only float if it's less dense than water (or whatever you're trying to float it in). Ok, you can also get a sphere to float if it's very tiny. This ...
what exactly is sooo special about walking upright, and the whole homo erectus thing	<p> since then, scientists discovered "ardipithecus ramidus", a human-like hominid descended from the common ancestor of chimpanzees and humans. "ar. ramidus" engaged in upright walking, but not knuckle-walking. this leads scientists to conclude that chimpanzees evolved knuckle-walking after they split from humans 6 mi...	"Better" is a bit subjective, but it absolutely makes certain things easier. Consider how much harder it would be for us to carry things (such as basic tools) if we had to walk on all fours. At the same time, we lost something too - we're slower.
why do deer antlers all look different? how do they grow? what purpose do they have?	<p> one of the principal means of distinguishing the closely related black-tailed deer and white-tailed deer is the growth habit of the buck's antlers. in the case of the black tail and california mule deer, the antlers fork in an upward growth, whereas the other species' antlers grow in a forward direction. <p> this ...	They grow like normal bone, and are covered by "velvet" until they rub it off to expose the bone. They grow and fall off every year in male deer. There's a lot of genetics and environmental factors behind how they look. Healthy adult deer will have bigger and stronger antlers. And they are used for clashes between male...
why don't cats roar like lions?	<p> felines such as leopards and tigers also growl to signal territorial aggression, eliciting anti-predator responses from animals such as elephants. similar to human interpretation of growling, elephants are able to distinguish the threat level based on the individual growl and will respond accordingly; elephants wil...	Why should cats roar like lions? Cats and lions are related, but that doesn't mean they have the same habits. They're not the same species -- you might as well ask why humans don't live in trees, like apes do. Physically, a domestic cat wouldn't be able to roar like a lion: simply put, their vocal tracts are way too sm...
could a tax system where the civilians choose where the money goes work?	<p> for example, the state requires payment for its services in the form of taxes whether or not people desire such services. since an individual’s money is his property, the confiscation of money in the form of taxes is an attack on property. military conscription is likewise an attack on a person’s primordial propert...	No, bc theres lots of things out there the average citizen wouldnt put their money towards but they do in fact need. They just arent educated on why they need it. Itd be chaos. Programs would die left and right despite being very much needed.
why are some people against capitalism/what are the main arguments?	<p> prominent among critiques of capitalism are accusations that capitalism is inherently exploitative, that it is unsustainable, that it creates economic inequality, that it is anti-democratic and leads to an erosion of human rights and that it incentivizes imperialist expansion and war. <p> critics argue that capita...	The main arguments I've seen against capitalism are as follows: 1) Unchecked, it will create a divided society in which a small number of people hold all of the money. 2) By its very nature, it places greater importance on the creation of wealth than it does on the well being of the people in the society. 3) The concen...
when people faint, do they wake up refreshed like from a nap, or tired, or something else entirely?	<p> as with any syncopal episode that results from a cardiac dysrhythmia, the fainting does not depend on the patient's position. if they occur during sleep, the presenting symptom may simply be feeling hot and flushed on waking. <p> orthostatic hypotension is characterized by symptoms that occur after standing (from ...	Speaking from personal experience, fainting is kind of like accidentally falling asleep and then waking up confused, disoriented, unwell, and even more tired than you were before. Also, head injuries are far more likely especially if you faint while standing. What's interesting is that some people dream while they fain...
why do some tree seedlings cost more than others?	<p> the yield varies depending on the age of the trees. five- to seven-year-old orchards may yield about 6 t/ha (2.7 tons/acre), with harvests increasing progressively until they stabilise at about 12–18 t/ha (5.4–8 tons/acre). seedling trees take longer to attain their maximal harvest, but eventually out-yield grafted...	Supply and demand. There could be a multitude of factors from number of seedlings a certain tree makes per year to the costs of raising such a seedling to the popularity of that species of tree in the market... you get the idea. It's Econ 101. Now if you're asking about a specific species of tree, you'll probably need ...
whats the point of me signing my copy of a receipt?	<p> the invoice and receipt are the printed record of the transaction and are legal documents. a copy of these documents would normally be handed to the customer, though this step may be dispensed with. in many countries, a retailer may be under a legal obligation to provide a receipt to a customer which shows the deta...	In most cases it's to initial that you received the money so you can't go back later and claim they forgot to give it to you.
why is the star wars prequel trilogy ridiculed so much in comparison to the original movies?	<p> when asked about the possibility of a "family guy" retelling of the other "star wars" trilogies, alec sulkin stated that a spoof of the "star wars" prequel and sequel trilogies were unlikely to happen due to the difficulty and struggle of spoofing "the empire strikes back" and the 2012 disney acquisition of lucasfi...	Because they simply were inferior when compared to the original trilogy. This doesn't mean that they were bad movies (even though I think that they were). It just means that they didn't live up to the quality of film that the original trilogy had.
given the stresses on our oceans and forests, does our biosphere currently produce a surplus of oxygen or are we running at a deficit? could we run out of oxygen in the future?	<p> in nature, free oxygen is produced by the light-driven splitting of water during oxygenic photosynthesis. according to some estimates, green algae and cyanobacteria in marine environments provide about 70% of the free oxygen produced on earth, and the rest is produced by terrestrial plants. other estimates of the o...	In order to get enough food to feed the population we need a lot of plants. And these plants alone is enough to produce oxygen for the population. It is basic chemistry that the amount of plants you need to generate enough food for a person produces exactly the same amount of oxygen that the person needs. This is also ...
direct x	<p> microsoft directx is a collection of application programming interfaces (apis) for handling tasks related to multimedia, especially game programming and video, on microsoft platforms. originally, the names of these apis all began with direct, such as direct3d, directdraw, directmusic, directplay, directsound, and s...	DirectX is the way that your game communicates with your graphics card. Microsoft takes requests from game developers and makes a list of features that game developers want, but can't do right now. Microsoft then goes to AMD and NVIDIA, and says, "Hey, these are some things that game developers want to be able to do. W...
why do people moan when stretching?	<p> in its most basic form, stretching is a natural and instinctive activity; it is performed by humans and many other animals. it can be accompanied by yawning. stretching often occurs instinctively after waking from sleep, after long periods of inactivity, or after exiting confined spaces and areas. <p> bullet::::- ...	People don't always. It's more of an exhale/sigh after the stretch.
why does every body fluid tast salty except for spit?	<p> spittoons are flat-bottomed, often weighted to minimize tipping over, and often with an interior "lip" to make spilling less likely if they tip. some have lids, but this is rare. some have holes, sometimes with a plug, to aid in draining and cleaning. <p> also unlike snus, dip often causes the user to produce exce...	Also ELI5 how OP would know this?
fur on coat hoods?	<p> historically, hoods were either similar to modern hoods, often forming part of a cloak or cape, or a separate form of headgear. hoods with short capes, called chaperons in french, were extremely common in medieval europe, and later evolved into big hats. soft hoods were worn by men under hats. hoods have also been ...	Pretty much the same way that fur works in general. One of the best insulators is just plain old air. Heat transfers in a few ways, but the one you're going to run into most in cold environments is conduction, where your warm stuff is touching cold stuff (air) and some of your energy leaves to the cold air. Insulation ...
why energy drinks are more expensive then othersoft drinks?	<p> the drinks at uniq are priced according to a "drink stock market", which updates the drink prices by increments of about 10 cents every few minutes depending on their popularity. popular drinks become more expensive, while unpopular drinks become cheaper. <p> the profits are lower than expected thus drinks becomes...	Can't say for sure but there are a couple factors. 1. Because they can. People will pay it so why not charge it. The same argument you make could be made of almost any non-staple food. Coke costs pennies/can to produce and get to market yet you pay 1.00 for it. 2. Ingredients. Lots of energy drinks contain ingredients ...
if prostitution is so common and active on craigslist, why doesn't the police just arrest them all?	<p> law enforcement is corrupt. police target foreigners who are with prostitutes, telling them it is illegal for two unmarried people of opposite sexes to be in the same hotel room, and then asking for a "fine". during police crack-downs, any single woman in a nightclub when raided is likely to be arrested as a prosti...	That would take resources they're using for other things. Prostitution isn't a high priority in a lot of places.

No one actually cares that prostitution exists. The things law enforcement care about are: 1) Appearance - This is why prostitutes on the street get rounded up. 2) Violence - Prostitutes are often "pimped" aka threatened by a man if they dont make him enough money, in exchange for limited protection and collection serv...
how do they implode/destruct megastructures in large cities and confine the destruction to one area?	<p> megastructure is an architectural and urban concept of the post-war eras which envisions a city or an urban form that could be encased in a massive single man-made structure or a relatively small number of interconnected structures. in a megastructural project, orders and hierarchies are created with large and perm...	They do this by causing one part of the building to collapse at a different time than another. Watch a few implosion videos, you'll see the whole building kinda "shift" usually in one direction. If you blow the supporting columns at the left side of the building first, then rapidly blow columns going left to right, the...
in nature documentaries, how do they get the sound of the animals being chased from so far away, while not getting any sound from the helicopter they're filming from?	<p> the shooting was carried out having resorted to ultra perfected materials: drones, subaquatic cameras, helicopters, hot-air balloons, flights in microlights. it is the actor guillaume de tonquédec who lends his voice to the narration of the film. all these ingredients have permitted the genre of animal documentary ...	It's often edited in using sound effects. When it's done well, you can't notice. When it's done badly it's cringe-worthy and annoying.
why aren't democratic candidates proposing defense spending cuts?	<p> according to a pew research poll in march 2010, 31% of republicans would be willing to decrease military spending to bring down the deficit. a majority of democrats (55%) and 46% of independents say they would accept cuts in military spending to reduce the deficit. <p> currently, congress wants to cut defense spen...	Politicians are terrified still (post 9/11 thing, but also kinda always) of being seen as soft on "defense." Any proposed cuts to our military budget wil be portrayed as such, mostly by those pols who get lots of $$$ from military contractors, and the ever-compliant "liberal" media.
the math in this article about microsoft buying minecraft. spending 2.5 billion and breaking even on 25 million in interest or whatever makes no sense to me.	<p> hal singer of the "micro-8 newsletter" published an open letter to ed roberts of mits. hal pointed out that mits promised a computer for $395 but the price for a working system was $1000. he suggested a class action lawsuit or a federal trade commission investigation into false advertising was in order. hal also no...	If Microsoft didn't buy anything with its cash and just let it sit in something that gained interest, it would have made $25 million on that $2.5 billion (savings accounts typically are around 1% return). They're saying that the purchase of Mojang and Minecraft is worth the $2.5 billion, and that as long as it's worth ...
why do some females leave an extremely strong lingering , fish-like smell in the bathroom?	<p> some time after leaving the body, urine may acquire a strong "fish-like" odor because of contamination with bacteria that break down urea into ammonia. this odor is not present in fresh urine of healthy individuals; its presence may be a sign of a urinary tract infection. <p> trichomoniasis, a sexually transmitte...	vaginas can give off a pretty wide range of odors for a pretty wide range of reasons. Fishy smell is one of them and it can sometimes mean nothing and be normal for a women or it can mean something is wrong especially if is pungent like a bacterial infection or something along those lines.
how do orally ingested medications fulfil their purpose if they end up in the stomach?	<p> many drugs as tablets, capsules, or drops are taken orally. administration methods directly into the stomach include those by gastric feeding tube or gastrostomy. substances may also be placed into the small intestines, as with a duodenal feeding tube and enteral nutrition. enteric coated tablets are designed to di...	They're absorbed into the bloodstream in your intestines, just like the nutrients in your food.
what is a special prosecutor and how will this person be able to finish an investigation into the russia stuff. how is this person any different from other "insiders"	<p> the prosecutor general and his office are independent from the executive, legislative and judicial branches of government. the investigative committee of russia, sometimes described as the "russian fbi", is the main federal investigating authority in russia, formed in place of the investigative committee of the pro...	There is no special prosecutor, that was a specific role which granted a large degree of freedom to conduct an investigation without political interference. The law used to appoint special prosecutors expired in 1999. The role announced today for Robert Mueller (a former FBI director) is as a special counsel. While he ...
how do glaucoma eye drops work? how do drops like travacom, timolol, etc... reduce the intra ocular pressure?	<p> eye drops used in managing glaucoma help the eye's fluid to drain better and decrease the amount of fluid made by the eye which decreases eye pressure. they are classified by their active ingredient and they include: prostaglandin analogs, beta blockers, alpha agonists, and carbonic anhydrase inhibitors. there are ...	Paraphrasing the text below. There are "valves" in the eye that control how much fluid is allowed to escape. The medication causes these "valves" to stay open, which reduces the volume of fluid in the eye. That leads to lower eye pressure and prevents progressive damage to your optic nerve. Mechanism Of Action Latanopr...
is there actually any significant difference in the chemical composition of household cleaners which claim to be for the "kitchen" or "bathroom", or are they all basically the same thing?	<p> the cleaning industry is quite big as different types of cleaning are required for different objects and different properties. for example, cleaning an office space requires the services of a commercial cleaner whereas cleaning a house requires domestic cleaning services. depending on the task, even these categorie...	Not in their chemical composition but in their physical composition. Bathroom usually means ceramic tile and porcelain and kitchen usually means linoleum, stainless steel, and veneer cabinetry. Ceramics are hard. In fact they are some of the hardest materials found in most homes short of glass, silica, or diamond. So a...
what are "germs"? when a dirty kitchen has "harmful germs," which specific bacteria or viruses are present?	<p> the main sources of infection in the home are people (who are carriers or are infected), foods (particularly raw foods) and water, and domestic animals (in the u.s. more than 50% of homes have one or more pets). sites that accumulate stagnant water—such as sinks, toilets, waste pipes, cleaning tools, face cloths, e...	"Germs" in common use can mean a virus or bacteria. Bactria make up the bulk of biomass on the Earth. In fact, most of the DNA in your body isn't "you". When it comes down to it we're nothing more than very successful hosts for a whole range of bacteria that live in our digestive system. "Harmful germs" can be any bact...
what does it mean when the potus signs a bill? can potus just decide not to?	<p> if the president or governor approves of the bill, he signs it into law. according to of the constitution, if the president does not approve of the bill and chooses not to sign, he may return it unsigned, within ten days, excluding sundays, to the house of the united states congress in which it originated, while th...	It means the President approves of the bill. When he rejects it, it's called a veto. When that happens, Congress votes on the bill again to determine if they can override this veto.
why, after hundreds of thousands of years of being around plants, are humans still allergic to pollen? shouldn't we be more immune by now?	<p> it is common to hear people say they are allergic to colorful or scented flowers like roses. in fact, only florists, gardeners, and others who have prolonged, close contact with flowers are likely to be sensitive to pollen from these plants. most people have little contact with the large, heavy, waxy pollen grains ...	Allergies are a result of the over active immune system. 'Developing immunity' isn't really the problem. Many plants we are allergic to are not plants that we co-evolved with.
why, after hundreds of thousands of years of being around plants, are humans still allergic to pollen? shouldn't we be more immune by now?	<p> it is common to hear people say they are allergic to colorful or scented flowers like roses. in fact, only florists, gardeners, and others who have prolonged, close contact with flowers are likely to be sensitive to pollen from these plants. most people have little contact with the large, heavy, waxy pollen grains ...	A pollen allergy will not prevent reproduction, therefore it will not be removed from the gene pool. Natural selection does not achieve perfection. It achieves "good enough"

You're living in unnatural conditions. Our immune system is evolved to be suitable for life in an environment full of dirt and animals, insect bites and the associated foreign fluids, and with our bodies containing numerous parasitic infections e.g. tapeworms, lice. People who live in similar conditions today don't get...

The immune system relies on encountering pathogens during the early stages of life in order to properly develop. This means that it needs to encounter all kinds of things, harmful or not, in order to figure out which ones are worth fighting and which ones are harmless. There is a theory that we have achieved such a lev...

To give some further background on the immune system: Allergies are caused by your immune system reacting to specific molecules. Your immune system has several varieties of antibody (the parts that detect pathogens and cause immune reactions). Five in fact: * IgA * IgD * IgE * IgG * IgM IgE is the antibody wh...
why do dogs bite air?	<p> a dog's first instinct to unpleasant stimulus is not a bite. a dog will use several techniques to stop what he perceives as a threat before he resorts to biting. therefore, it is important to avoid suppressing important canine communications such as growling and snarling. if a dog learns that a growl is an inapprop...	Because she feels something there. Dogs pick up things with their mouths, and while they may paw at items to get to them (like a bone in a corner or under a table), when it's in reach they go after it with their mouths. Other animals, who are more inclined to use their paws, will do so, as in this video.
how did the hollywood silencer come about?	<p> the silencers is an american pathécolor spy film spoof motion picture released in 1966 and starring dean martin as agent matt helm. it is loosely based upon the novel "the silencers" by donald hamilton, as well as another of hamilton's helm novels, "death of a citizen." <p> american inventor hiram percy maxim, son...	Movies are made to tell stories. A story tends to be much more dramatic when tools can be made to fit the needs of the story. Dramatic movies generally do far better than documentaries. It's not just siliencers, elite troops always failing to hit the hero; grenades and explosives generally to meet the needs of the stor...
compound interest	<p> compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. it is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest. compoun...	Let's say that you want to borrow $100 from me. I say that it's fine but each week you don't pay me back, you owe an extra 10%. It seems fair to you and you agree. After the first week, you've made no payments to me so 10% of $100 means you owe me an extra $10. Now you owe me $110. Another week goes by and you still ha...
how do birds fly so closely in front of cars without being hit?	<p> bird strikes can damage vehicle components, or injure passengers. flocks of birds are especially dangerous and can lead to multiple strikes, and damage. depending on the damage, aircraft at low altitudes or during take-off and landing often cannot recover in time. us airways flight 1549 is a classic example of this...	It's just luck and timing, believe me sometimes they don't make it o_o
how do hospitals quarantine patients?	<p> in cases where infection is merely suspected, individuals may be quarantined until the incubation period has passed and the disease manifests itself or the person remains healthy. groups may undergo quarantine, or in the case of communities, a cordon sanitaire may be imposed to prevent infection from spreading beyo...	Depends on the pathogen. If it's something airborne like TB, the patient will be placed in a negative-pressure room, meaning the ventilation system in the room keeps the air pressure a tiny bit lower (you don't even feel the difference) than outside, so air always rushes into the room and not outward. For a diagram and...
how can temperature/weather vary so much at different points on the earth that are the same distance from the equator?	<p> still another definition states that the thermal equator is the latitude at which insolation is identical throughout the year. this is not the same as the astronomical equator because the earth reaches perihelion (the minimum distance from the sun in its orbit) in early january and is at aphelion (maximum distance)...	Climate (the relatively constant patterns of weather and temperature over millennia) is controlled by wind and ocean currents. Water carries a lot of energy in its temperature, so a current coming from the equator to the north or south will create a much warmer climate than a current coming from the north or south pole...
if nazi war criminals were given (somewhat) fair trials at nuremberg then why wasn't osama bin laden given one?	<p> former nuremberg prosecutor benjamin b. ferencz stated it was unclear if bin laden's killing was justified self-defense or premeditated illegal assassination, and that "killing a captive who poses no immediate threat is a crime under military law as well as all other law," a view also held by legal scholar philippe...	Pretty much impossible to take him alive. The nazis surrendered and went to court. OBL spent a decade on the run, hiding with armed guards.
why are some economies self-sustaining while others require a massive trade surplus just to function?	<p> the supply-side economists (and others) have argued that raising international competitiveness through policies that promote traded goods sectors' productivity (at the expense of other sectors) will increase a nation's gdp, and increase its standard of living, when compared with treating the sectors equally. the ba...	A lot of the value produced in the USA is by peoples brains and not their hands. If you import a ton of cheap garbage from china for pennies and export knowledge in medicine, engineering, business, finance, etc. For hundreds of dollars per hour, its hard to look at that as being BAD for the us.
why cannot signatures be forged/copied perfectly, with sufficient resolution and the right ink?	<p> an ink signature could be replicated from one document to another by copying the image manually or digitally, but to have credible signature copies that can resist some scrutiny is a significant manual or technical skill, and to produce ink signature copies that resist professional scrutiny is very difficult. <p> ...	People are missing the point. Yes you can easily create an exact digital copy of a signature. A decent scanner, simple cut and paste, and you can do it in seconds. That is why legal documents must have original signatures on them (ink on paper).
how do tight rope walkers set up the tight wire over a long distance?	<p> a ropewalk is a long straight narrow lane, or a covered pathway, where long strands of material are laid before being twisted into rope. due to the length of some ropewalks, workers may use bicycles to get from one end to the other. <p> tightwire-walkers typically perform in very thin and flexible, leather-soled s...	Not an expert or anything, but I do know that they often, where necessary, get a small rope across the opening by carrying it manually, then they tie that ropes end to a larger rope and pull the larger ropes end over the opening, then if necessary, tie that to a larger one, etc., as many times as is necessary to get th...
what happens to passengers when a plane flies 45,000 feet into the air?	<p> if a pressurized aircraft suffers a pressurization failure above 10,000 feet (~3,000 meters), then it could be deemed as an emergency. should this situation occur, the aircraft should begin an emergency descent and oxygen masks should be activated for all occupants. in the majority of passenger aircraft, the passen...	Not much. The rated ceilings for passenger aircraft is between 40k and 50k (45.1k for a 747-400), depending on the specific aircraft. Fuel economy goes to shit, and there might be some unexpected turbulence, but the passengers probably wouldn't notice. You're going to have lift and engine problems before you have cabin...
why is it so difficult to not flinch when something jumps out at you on a screen(like a scary movie for example) even though our brain registers that it is fake and expected?	<p> he also proposes a natural 'motor' response to seeing the actions of others: if we see a knife hacking off a person's leg we wince away, if we see someone dance we move in the same ways, we feel the injuries of others as if we had them ourselves. <p> the resolution on animation can also cause users to experience t...	Reflexes occur much faster than rational thought. It's been shown that people reacting to painful stimuli move away from the stimuli before the rational centers of the brain are even activated. This means that your rational brain is not even involved when you flinch - you know it's fake, but that knowledge isn't rele...
what are movie critics, and why is there opinion valued so highly?	<p> there are scholars who point out that mass market films such as those produced in hollywood appeal to a less discerning audience. this group then turns to film critics as a cultural elite that can help steer them towards films that are more thoughtful and of a higher quality. to bridge the disconnect between popula...	It's not that they just watch movies and get paid for writing about them. Most come from the industry, are familiar with the director's style - and generally have greater insight into the artistic aspect of film, and are more aware of the subtleties in film making. It's like the difference between a musician analyzing ...
with so many "knock off" products of coca cola, why haven't they released a coca cola brand ice pop?	<p> because several 7 up bottlers also distributed colas such as coca-cola, pepsi-cola or eventual 7 up sister drink rc cola (which introduced another caffeine-free cola, rc 100, in 1980) they refused to distribute like cola – limiting its availability. <p> american sales did not live up to early expectations mainly d...	My guess would be due to the icee contract and how it is written.
what is the deal with all these people talking about fake snow that burns like plastic?	<p> "fake plastic snow" is an episode from the dramedy series "ugly betty". it is the eleventh episode overall in the series, but in the united states, canada, and australia, it is the tenth episode, which was written by veronica becker and sarah kucserka and directed by jim hayman. the title of this episode refers to ...	someone posted a video of a person holding a snowball with a pair of tongs and applying either a lighter or a blowtorch to it (I can't remember which it is.) Anyway, the flammable source caused snow to evaporate, which looked like "smoke" and simultaneously left soot stains on the snow, leading people to the erroneous ...
how come when you apply a glue stick to paper, the paper curls up?	<p> paper is manufactured by forming pulp fibers into a mat on an open mesh screen (a deckle), and then drying and pressing this mat into paper. large areas of inkjet color, such as in graphics and photographs, soak the paper fibers with so much moisture that they swell and return to their original shape before pressin...	I believe it's because as the glue dries, it loses volume and shrinks, and both the glue and paper are stuck, so it contacts and wrinkles.
what exactly is the difference between arab and persian?	<p> the term persian arab is rarely used as a self-appellation. most tend to identify more strongly as either persian or arab and consider themselves to be members primarily of one ethnic group, but at the same time being aware of their mixed background. for many the most important factor determining their identity is ...	I mean, this is kind of like asking "what's the difference between French and German?" Well, a lot. Arabs speak Arabic, Persians speak Farsi Arabs are principally from modern day Syria, Iraq, Egypt, Lebanon, Jordan, Kuwait, Qatar, UAE, Oman, Yemen, and Saudi Arabia while Persians come from modern day Iran. Persia exist...
how does a flash lamp excite electrons?	<p> the electric flash-lamp is a device that uses an electrical circuit to trigger a fuse to ignite explosive powder such as magnesium, for a brief sudden burst of bright light "flash" from a chemical reaction of flash powder burning. it was principally used for flash photography in the early 20th century, but had othe...	All light excites electrons. The photons that make up the light collide with the electrons in a substance, get absorbed, and cause the electrons energy to increase. Electrons can then reemit the photons to decrease in energy.
how do i go about getting dreadlocks?	<p> a variety of other starter methods have been developed to offer greater control over the general appearance of dreadlocks. they can be formed through a technique called "twist and rip", as well as backcombing interlocking and palm rolling. together, these alternative techniques are more commonly referred to as "sal...	ELI5 is for conceptual explanations, not how-to's or personal problems. As such, I've removed this post.
when do you stop worrying about heat from air friction, and start worrying about air compression.	<p> bullet::::- "kinetic heating". as the airspeed increases, more and more molecules of air per second hit the aircraft. this causes a temperature rise in the direct reading thermometer probe of the aircraft due to friction. because the airflow is thought to be compressible and isentropic, which, by definition, is adi...	Engines that use supersonic air compression (scramjets) for propulsion start working around mach 5.
what does talking with a psychotherapist do to you, that makes you recover?	<p> psychoeducation offered to patients and family members teaches problem-solving and communication skills and provides education and resources in an empathetic and supportive environment. results from more than 30 studies indicate psychoeducation improves family well-being, lowers rates of relapse and improves recove...	First, you're talking to someone who is empathetic towards you but objective towards the situations you need to talk about. Second, talking about situations sort of takes them out of your head and makes them easier to process. Third, a therapist can give insight on how to moderate emotions and teach skills to use when ...
how does my horoscope always seem to relate to something happening in my life?	<p> in common usage, "horoscope" often refers to an astrologer's interpretation, usually based on a system of solar sun sign astrology; based strictly on the position of the sun at the time of birth, or on the calendar significance of an event, as in chinese astrology. in particular, many newspapers and magazines carry...	Because these comments are normally generalized so that most individuals can make a connection.
why do some mix of colors get their own name (eg. pink-which is red & white), while other colors are just named by the two colors, (eg. light blue-which is white and blue)?	<p> usually, colors with the same hue are distinguished with adjectives referring to their lightness or colorfulness, such as with "light blue", "pastel blue", "vivid blue". exceptions include brown, which is a dark orange. <p> colors vary in several different ways, including [[hue]] (shades of [[red]], [[orange (colo...	There isn't really a good reason. How colours are talked about and which shades get their own names is influenced greatly by culture. For example, people with red hair are called that despite having orange-y hair because orange used to be considered a shade of red. Then when the orange fruit was imported to English-spe...
what makes gordon ramsay regarded as one of the best chefs in the world?	<p> gordon james ramsay (born 8 november 1966) is a british chef, restaurateur, writer, television personality and food critic. born in johnstone, scotland, and raised in stratford-upon-avon, england, ramsay's restaurants have been awarded 16 michelin stars in total and currently hold a total of seven. his signature re...	His restaurants have won 16 Michelin stars. This is like an actor winning 16 Oscars. It means that experts in his field consider his work among the best. There are only two chefs whose restaurants have earned more than 16.
how did the crash of the mortgage markets result in people unrelated to the housing industry losing their jobs?	<p> the decline in the housing market set off a domino effect across the u.s. economy. when home values declined and adjustable rate mortgage payment amounts increased, borrowers defaulted on their mortgages. investors globally holding mortgage-backed securities (including many of the banks that originated them and tra...	Banking crises can have flow on effects because of how integral banking is to modern business. For example, lots of businesses borrow money on relatively short timescales to have the cashflow to pay employees. When the banks get hit by a crisis and don't have enough money available, they can't lend out money. Borrowers...
what is the process for movies to film scenes at major sites that are usually crawling with activity?	<p> the directors met each other at film school, where they became friends. the actors were recruited locally, and they did not use auditions. instead, actors were approached and asked what they could bring to the character. principal photography took place over two weeks in january 2014 in mansfield, victoria. the dir...	Money. They just pay into the local economy and get to shoot there. The city area will get notified in advance. City workers help close off the area needed while filming as everyone flocks to watch the filming happen. Win win for all.
what long term effects does a polar vortex have on a state/region?	<p> the polar vortex is a whirlwind of especially cold, dense air forming near the poles that is contained by the jet stream, a belt of fast-flowing winds that serves as a boundary between cold polar air and the warmer air of other hemispheres. because the power of the polar vortex and jet stream is derived partly from...	As a biologist, I can definitely tell you that it will have a lasting impact on what plants and animals as well as insects or even microbes survive into the spring. Many organisms living in nature live and what humans consider pretty extreme poverty. Little protection against the elements as well as often insecure food...
why the american legal purchasing age of alcohol differs with that of tobacco.	<p> he his colleagues have conducted research on the long-term effects of the minimum legal drinking age showing that youth who were legally restricted from drinking until age 21 had lower risk for alcoholism and other problems later in adulthood compared to those who were legally permitted to purchase alcohol at earli...	Alcohol, like tobacco, used to be legal at age 18. Basically, states were having trouble related to automobile safety. Specifically, drunk driving was causing too many collisions and too many deaths. The federal government, after being urged by Mothers Against Drunk Driving, had come to the conclusion that one way to l...
what exactly is going on with the right to repair act?	<p> the right to repair concept has generally come from the united states. within the automotive industry, massachusetts passed the united states' first motor vehicle owners' right to repair act in 2012, which required automobile manufacturers to provide the necessary documents and information to allow anyone to repair...	The wiki for it covers it pretty simply: Basically legislation proposing that manufacturers shouldn't be the only ones able to offer service on vehicle computer systems, which would create a monopoly on that type of service.
mute people.	<p> deaf-mute is a term which was used historically to identify a person who was either deaf using a sign language or both deaf and could not speak. the term continues to be used to refer to deaf people who cannot speak an oral language or have some degree of speaking ability, but choose not to speak because of the neg...	There are many different kinds of mutism. One is called selective mutism. This is a person who can speak but chooses not to. He may speak in certain situations or to certain people, or he may not speak at all. Some people are mute because of damage to their vocal folds. This may have been due to injury or accident, s...
the controversy about big pharma	<p> the term "big pharma" is used to refer collectively to the global pharmaceutical industry. according to steve novella the term has come to connote a demonized form of the pharmaceutical industry. professor of writing robert blaskiewicz has written that conspiracy theorists use the term "big pharma" as "shorthand fo...	It's a for profit business and economics don't really work well with health stuff. Supply and demand rapidly breaks down when the "demand" is to not die. So it's very easy to become very exploitative. If someone can say "you gotta buy this or you die" you basically can make that person pay any amount they have and ther...
google reader (or rss feeds in general)	<p> google reader was an rss/atom feed aggregator operated by google. it was created in early 2005 by google engineer chris wetherell and launched on october 7, 2005, through google labs. google reader grew in popularity to support a number of programs which used it as a platform for serving news and information to peo...	Oh, hello, five-year-old that knows how to use reddit. Do you like water? Me too! Some people like water so much they go to different places to pick up water each day, and the stores sell different pieces of water each day. Different stores sell different colors of water, so people will drive by each store and pick up ...
why do birds leave a white residue whenever they hit a window?	<p> further, birds recall and avoid objects that are both conspicuous and foul-tasting longer than objects that are equally foul-tasting but cryptically coloured. this suggests that wallace's original view, that warning coloration helped to teach predators to avoid prey thus coloured, was correct. however, some birds (...	The residue is made up of the oils, dirt, and dust that coats the bird's feathers. When they hit a window, the coating gets smeared onto the glass where the bird makes contact.
why does being in the sun help with my depression?	<p> due to symptoms of low mood and energy, individuals with depression may be likely to have behaviors that are counter to good sleep hygiene, such as taking naps during the day, consuming alcohol near bedtime, and consuming large amounts of caffeine during the day. in addition to sleep hygiene education, bright light...	The sun light is very important because it helps our body to produce serotonin and melatonin, two hormons making us awake and more dynamic.
