why does wind feel colder than stagnant air?
|
[
"The wind or a fan doesn't actually cool anything. All it does is move air across surfaces faster. You are feeling heat leave your body faster because that heat is moving along with the flowing air. We perceive that loss of heat as \"cold\"."
] |
[
"Oooh makes air come out faster causing a small amount of wind chill that makes it feel colder. Aaah makes the air come out slower so you feel the tempurature of where the air came from (inside a body)"

Why do spins/jumps in sports continuously get more intense?
|
[
"It's primarily two things: 1. Better equipment. Technology plays a larger role in these things than most people realize. Simply the fact that modern equipment is lighter, stronger, has more flex, rebound and spring allows athletes to do things that were literally impossible 20 years ago. 2. Athletes start training at a much younger age now. They are able to master many techniques sooner - including those techniques that led to that first backflip or triple McTwisty or whatever. Instead of figuring out how to do something, they learn how to do it and figure out how to improve on it."

[
"The events which are based simply on how quickly you can swim a distance are called freestyle. Slower strokes have their own events, as you mentioned these strokes can take more energy which makes them more difficult so the competition is still interesting. Another way to spin your question would be \"why do they use hurdles, it's slower and less efficient than just running\"."

What causes free WiFi hotspots at hotels etc to be so patchy and unreliable.
|
[
"Setting up a wifi mesh is expensive, and frankly not worth the effort and cost for many small motels. Larger ones try and do cheaply. The effective result is, small motels just put a consumer router in the lobby or manager's office, and it's range is a hundred feet from there. Large ones may have a mesh, but insufficient access points to cover the entire complex."

[
"They can, My in-laws don't have internet in their house, they just have a hotspot device that they turn on and off when they need internet. But generally, wi-fi is faster and more reliable than cellular data. Even 4G LTE is not as fast as AC internet speeds."

Why does the moon cause waves in the ocean but not on smaller bodies of water like lakes?

Why does the value of currencies fluctuate?
|
[
"The fluctuations are a result of supply and demand for that currency. For example, let's say there's suddenly huge global demand for American widgets. Companies all over the world want to buy those American widgets to sell in their own countries. Those foreign companies would drive up the demand for US Dollars in order to purchase the widgets, which makes US Dollars rise in value in relation to other currencies. There are better examples and explanations as well - try using the search bar to see if you can't find any of the previous answers."

"Currency exchanges can slow down businesses in two ways: * it costs money to change currency, so every deal you make outside of your country will cost a little more * currencies exchange rates fluctuate...the million franc deal a German company entered into 6 months ago might not be profitable today if franc lost their value"

Reddit bots. What are they? How do they work? Who makes them? How do you make one?
|
[
"A Reddit bot is a program that runs on someone's computer. This program can access Reddit through a computer-friendly interface. They typically work by periodically requesting a list of posts or comments, then searching through the text of those posts or comments looking for a certain string of letters, then they put together a pre-determined response and post it. They're made by anyone who knows how to program and wants a bot. I made one a few months back when there was a scammer trying to rip off honest people. The program would alert me when they posted so that I could show up and call him out on his bullshit. The easiest way to make one is to download the Python language if your system doesn't already have it, then get the PRAW library which gives you convenient ways to access Reddit. From there you write the logic of what you want the bot to do (note: requires knowledge of programming) and you run it. There are other packages available in other languages as well."

Why does shaking a liquid mix everything together and not separate it?
|
[

"Though the contents were not changed how they mix has changed. Something easier to visualize is a milk chocolate bar. If you have put one of those in the freezer and take it out you notice the powder white film along the outside. That is the maltose sugar that separates from the chocolate because it freezes at different temps. The effect on your soda is similar. Of course if you shook the can up since it is a liquid you could probably remix the flavors but that would give you other problems."

Why do wedding dresses turn yellow after a period of time?
|
[
"Many white things turn yellow over time. Generally it's the result of sunlight or oxidation. White cotton generally gets its white color from being bleached and washed with fabric whiteners. Fabric whiteners and brighteners are temporary dyes that add a slight blueish tint to the wash. Modern ones use optical brighteners _URL_0_ In the old days people used Reckitt’s Blue, which was a blue bar of soap, which was scrapped and the flakes added the wash. It coated clothes in a blue powder that made yellowish clothes look white at least until the powder fell off from wear. Edit: minerals like iron in the water, makeup and sweat also make white clothes turn yellowish."

How come most houses have slanted roofs but most other buildings are flat?

How is Oxygen stored in water and how can fish extract it to breathe?
|
[
"Oxygen is just dissolved in water, in the same way that you can dissolve sugar in water, or carbon dioxide in water to make a soda. Fish gills have a huge surface area to maximize how much contact they make with the passing water. Oxygen molecules cross the membrane of the gills just like they do in our lungs, and then get carried to the rest of the body through the fish's circulation!"
] |
[
"The ocean is full of creatures who do not have lungs. Also, insects don't have lungs, but they have holes on their bodies where the Oxygen and Carbon Dioxide exchanges take place. tl;dr lungs aren't required to breathe, but they're a very efficient way to do so."

What is this new "Common Core" math?
|
[
"First, an important thing to remember is that the Common Core is a set of standards, meaning it is up to the teacher how to reach those standards, so if you find some of the problems odd, the blame is more on the teacher. Anyways, the purpose of common core as I understand it is to emphasize students not memorizing numbers, formulas, equations, etc. but to learn how to think critically and use basic knowledge in more complicated problems mirroring the real world. In geometry, you'd be taught the various rules, such as what are complementary angles, and then you'd need to be able to figure out more complicated real world problems. TL;DR If I have it right, the purpose of the CC standards is to make students better critical thinkers using math. Being able to take basic math knowledge and figure out more complicated real world-like problems is the goal."

Why is there ringing in your ears in complete silence?
|
[
"there are little tiny \"hairs\" in your ear that are actually very sensitive cells that detect vibrations in the air that you brain interprets, thus, you can hear things. Sometimes, these little \"hairs\" get flattened out, by a very loud sound or by a natural quirk in your body. The ringing you hear is the the cells straightening themselves back out slowly. Imagine them like carpet that was under some furniture that you just moved. Your brain is wired to interpret any movement from them as sound, so you get that phantom sound at a low level as they stand back up. Edit: Children of Men was an AWESOME movie, but the whole swan's song theory (that when you have ringing in your ears you will never hear that pitch again) is a common misconception."

"Hurricanes are named by the World Meteorological Organization specifically to make it easier for people to find and track news about them in order to better prepare.

When we say someone has a "good" or "poor" vocabulary, how many words more or less are in their functional command?
|
[
"Depending on who you ask, there are around a million English words. You can take vocabulary tests that check you know just a couple of hundred words, chosen to cover a wide range, and they tend to tell you how many \"word families\" you know. The idea of a word family is explained as > words such as nation, national, nationalise, and international are all considered to be members of the same family Apparently native english speakers know some 20,000 word families. If you know more than that, your vocab might be considered \"good\", if you know fewer it might be considered \"poor\". I just took one of those I found from google and it said [26,900](_URL_0_) word families. I don't know how many I got wrong, but that might give you an idea of the general range we're talking about. Edit: I did a different one which said [27,800](_URL_1_), so you can see this method has some variance in it."

When public bathrooms are moving more to no-touch required basins \ soap dispensers \ dryers, why do 95% of the doors open inwards, so that you have to pull a handle as you leave.
|
[
"Doors that open outwards may be blocked from the other side. So, a person may be trapped inside by being unable to push. By opening a door inwards, it greatly reduces the chance of the door not being able to be opened. A bathroom tends not to have any secondary exits. This is a researched guess on my part."

[
"Some people don't was their hands. That means that even people that do wash their hands still end up with fecal matter on their hands after touching the door handle or latch. I always wrap my fingers in paper towels to open and close doors then I use some hand sanitizer after I am clear of the bathroom just in case. Always close the lid before flushing too. Microscopic fecal matter erupts from the toilet during a flush and will soil your body, clothing and anything else that is within a few feet."

Why do movies/TV shows/commercials always seem to use empty opaque cups (i.e. a coffee cup) or other containers, when a simpleton like me can easily spot that they're empty just by watching?
|
[
"Continuity, if they use real drinks in a clear glass, and the scene requires them to take a drink, they would have to refill the glass to the exact original spot for each take (and a film can do up to 10 takes for each scene). And the actors would have drunk an unholy of water by the end. It saves a lot of trouble just to have them mime drinking from an empty cup."

Do today's video games keep you playing like casinos do, throwing you wins once in a while to keep you playing longer?
|
[
"There have been news recently of a patent filed by Activision for a system designed to goad players into buying more microtransaction items by doing things like matching them up against better players with premium items that the manipulated player doesn't have, to make them believe that they would be more successful in the game if they went ahead and bought the premium item. Directly after the purchase of the item, the game would make sure to match the players against worse opponents to make them feel good about their purchase. Activision claimed they haven't implemented the feature into any of their games…yet. Edit: For a somewhat more positive example from the same company, Hearthstone has a system where the chance of getting a Legendary card inside of a pack slowly increases the more packs you buy, to the point where you are absolutely guaranteed to get at least one Legendary every 40 packs you open."

"It's a matter of overindulgence and addiction. Casinos are designed to get you to keep spending your money, over and over, as much as you possibly can. Every single thing about the games and the atmosphere is built to suck you in and keep you playing until you are broke. It is a study in psychological manipulation. For the more observant, it's obvious the system is designed to pray on the weaker willed. The casino industry is predatory, and it contributes to financial ruin *by its very design*. Lotteries, on the other hand, are not as appalling. You don't have the flashing lights, the free drinks, or the complementary frequent player rewards. You don't have a system where people can sit all day and get stimulated. Scratchers are about as close as you see, but those are just little slips of paper that lose their appeal after a few minutes. It's much much harder for someone to get sucked in and blow all of their money."

Why does it hurt to move a limb after it "fell asleep"?
|
[
"You have nerves in your body that send signals to different parts to work-- specifically muscles. They begin from your spinal cord, branch, and extend all the way to your fingers and toes. Your arm or leg falls asleep when pressure is placed on the nerve or when blood is cut off from supplying the nerve. The effect is similar to when you hit your funny bone (your ulnar nerve) which can be painful, and cause the pins and needles sensation. People with more common nerve compressions which can be chronic may have diagnoses such as sciatica or carpal tunnel syndrome and experience a range of painful symptoms."
] |
[
"It's similar. Your fingers get stiff because the fluid in the joints (called synovial fluid) gets more viscous and doesn't move as well. Your forearm muscles also get weaker in the cold. And if the nerves in your forearm get cold enough, they won't be able to transmit any more, and your hand will basically be paralyzed."

- Why do smells get "burned in" to your nose? (Bleach, vomit, etc)
|
[
"It's because those particles are in aerosols, little droplets of water with other things mixed in. And those droplets get in your nose and deposit their contents on the mucosal lining. Eventually you secrete enough mucus to wrap them all up, you swallow that, and it's gone. But until that time you can still smell them because they are still there, just hanging out inside your nasal cavity."

"Everyone's sneeze smells are different. Some people that have sweet smelling honey or floral smell are due to the ketones in your bloodstream. (sometimes a sign of diabetes or liver disease if it smells like ammonia). Others might have a foul smell due to smelly saliva.

How come after drinking a lot of beer (calories), I want to eat something bad for me (more calories).
|
[
"This is going to be a very simple explanation, there are a lot of biological factors involved but this is basically it. Alcohol is a depressant, when you get drunk your consciousness decreases based on how much you drink. When this happens, people tend to become very instinctual. You start trying to fulfill your instinctual needs... Such as sex, sleep, and hunger. Now we go to the past, long story short, humans LOVE fat and greasy stuff. It kept us warm in the past. (Long long time ago)... So essentially, in your stupor state, you tend to like more fatty foods due to evolutionary instincts of liking fatty stuffs."

why were tv and movies black and white?
|
[
"Because the technology of how to create black and white photographs and moving pictures came first. Television at first was black and white too even though color movies already existed at that point. The technology to make color-tv was more expensive than b & w tv and the receivers for color were also more expensive. During the early phase of adoption they had to add color information in such a way as to not break anything for people with b & w tvs while allowing those with expensive new color tvs to get a color picture from the same signal. During the phase before it became normal some producers would create and broadcast shows in b & w despite color being available because it was cheaper to do so and not many would have the color receivers to see the difference."
] |
[
"Because of advertisers. Since on subscription services most of their revenue comes straight from the consumer they are willing to create more diverse content. So they might not have as many viewers but they're getting more money from less viewers. On network TV the advertisers want to be seen by as many people as possible so the producers are forced to put on shows that appeal to the most audience, your lowest common denominator. Also advertisers don't want their products associated to shows that may be offensive to someone. Same thing is happening on YouTube, advertisers are getting more restrictive on what they want their products being associated with so any thought provoking video will be demonetized. And all its left is rich kid vlogs, makeup tutorials, tech reviewers, click bait, top ten anything's, and grown ass men screaming into a microphone while playing a child's videogame."

Why helicopters and planes can't get out of the earth?

Can someone explain what it is about music theory that allows pretty much every song to be mashed with eachother in a way that fits?
|
[
"Songwriters are unimaginative. They use the same stupid chord progressions and scales and rhythms over and over and over and over again. The energy of a song is largely independent of the scale/harmony, so that's no barrier. Key doesn't matter because you just shift one song or the other up or down until the two songs match. And because we all use the same stupid scales, the chords often barely matter as well. The melody from All Star is mostly pentatonic which means it works with *virtually any* typical Western chord progression. There's a reason this is done with mostly pop songs and not, say, King of Limbs-era Radiohead."

Music from the outside appears to be an expression of the soul which is true, but music is bound by rules. If I want to play something happy I will use a major scale, if I want something sad I'll use a minor scale. Now the difference between analog and digital is how you can manipulate the sound waves, analog is very limited, digital is limitless, so when trying to portray a certain emotion, orchestrators were bound by musics rules but weren't able to make distinguishable and unique sounds for each of the wood instruments, which made for extremely similar sounding OSTs where as now, you can use the same four chords and it will fit into 100+ songs that sound nothing a like.

The difference between aftershave/perfumes and eau de toilette.

Why is it sometimes economically rational to keep loss-making firms afloat?
|
[
"The product may also be so socially or economically valuable that the government chooses to subsidize the industry. Many governments do this with basic services like electricity, water, and gas to control the price of those services. The price stays so low that the company operates at a loss, the government makes up the difference. This is usually a good deal for most consumers, they get their services at less than the free market price. Governments often also choose to subsidize farms to ensure a stable, secure food supply. You can't have a bad year put a bunch of farms out of business, food is important."

[
"Not all businesses operate on razor thin margins. Many tell their workers to take home minimum wage while they take huge amounts of money to their preferred tax shelter. Minimum wage laws only hurt businesses that could be just as easily hurt in other ways (economic downturn, increased supplier prices, etc)."

What makes C++ a better language than C? Or in other words, what are all the advantages of Object-Oriented Programming?
|
[
"Both C and C++ look similar, but there are features in C++ that C doesn't have. Most problems can be solved using either C or C++, but sometimes the extra features of C++ make solving the problem much easier. Think of it this way: You are trying to build something. You have the choice of using a toolbox containing one flathead screwdriver and a pair of scissors, or you can use a toolbox containing 12 different screwdrivers, a saw, a wrench set, and a bunch of power tools. Which would you choose?"
] |
[
"Practically speaking, all programming languages make trade-offs, and different programming languages prioritize some things, like performance, control, readability, and convenience, over others. For example, C++ prioritizes runtime performance, but must be compiled ahead of time and requires more lower level understanding. Python is generally a lot slower, but abstracts away certain kinds of complexity (such as memory management) and is generally easier and faster to develop. A lot like human languages, different programming languages also encourage different ways of thinking. Almost all the languages you mentioned are primarily designed to support what is called \"imperative\" programming. If you want to see something really different, look up a language that encourages \"functional\" programming, such as Clojure, Haskell, or Scheme."

How does applying heat to something actually relieve the pain?
|
[
"It depends upon the kind of pain. For muscle aches, heat causes blood vessels to relax and dialate. This means more nutrients are going into the area, promoting healing and carrying away toxins faster. For other sorts of pain - like a burn or an area swollen with infection, apply heat is a terrible idea. Cooling is effective as it causes blood vessels to clinch closed -and the problem is too much fluid in the area."
] |
[
"The cold causes arteries to constrict stopping blood from rushing to the area. This prevents further swelling and also helps the swelling go down. It has the added benefit of numbing the area reducing the pain as well."

Salt and ice - Why the burning sensation?!
|
[
"When salt meets ice it lowers the freezing point of the water. The result is super cold water. This is why salt is used to melt ice on roads, and why you use salt and ice to make icecream. The reason is that the salt goofs up the formation of ice crystals, making it much harder for the water molecules to line up and freeze into ice."

Why do all currencies undergo inflation over time?
|
[
"That's an over-generalization. The underlying resources that give value to a currency tend to expand over time. In the rare instances where they contract over the long-term - such as the Japanese population declining - currency can go in the opposite direction and deflate."
] |
[
"Under a gold standard, there are two prices of gold: the market price and the standard price The standard price is set by the government, and is usually the floor price of gold The market price is whatever buyers can get on the open gold market When the financial system is stable, the standard price and the market price don't differ by much When confidence is lost in the financial system, the market price of gold goes up. To stabilize the system, the government could either sell gold to lower prices, or withdraw currency. The latter causes deflation, which damages investing. Additionally, if the currency is the global reserve currency, there needs to be enough of it out there for use in global trade Edit: Additionally, gold price doesn't change primarily due to currency manipulation, but rather market prices. Usually, gold goes up when the rest of the market goes down, and vice versa. Gold is the reserve investors flock to when in crisis"

Why is it so hard to make friends after you turn 25?
|
[
"The biggest factor is opportunity. Young people are almost always set up in large groups due to school. This also happens at a time in their lives when they are very open minded. As you grow older your personality tends to solidify and you tend to judge other people more solidly then when you are young. You also don't tend to reach out of your circle to find new people as often. Now yes most adults work in places with a large number of other employees but the ages of those employees tends to be much more spread out than the ages of your peers when you're in school, and there is far less time for flat out socialization in the work place. **TL:DR** It's not you, it happens to everyone."

What causes the attraction to "odd" physical traits? My attraction to slightly gapped teeth, for example.
|
[
"Perhaps you were attracted to someone with this trait earlier in life, and you associate that trait unconsciously with a person who may have shaped your image of an attractive person. What is considered \"attractive\" can change from era to era, and culture to culture. One way or another we are exposed at an early age to what this image is. Straight and clean-white teeth are often a feature of the attractive people featured in media and culture, so not only do we factor that into our opinions but we imitate them to acquire some of that image. I find women that remind me of my first girlfriend have a different appeal to me than other women who may have other \"attractive\" features. Its not that my first girlfriend was stunning or conversely unattractive, but I associate with her appearance a generally successful relationship with someone I was attracted to."
] |
[
"Like most things considered attractive, you have to understand that it's personal taste. Some people like boney-skinny women, some people like enormously fat women, some people like women in some range between those. As said below it's associated with skinnier women and located very close to the genitals so has more of a sexual connotation than, say, visible ribs. And just about any part of a human body is fetishized by some group, like feet, hair, hands, breasts, buttocks, thighs, or even amputated limbs. It basically boils down to 1. prevailing societal opinion that thin is attractive, 2. association of the characteristic with thin women, 3. association of the characteristic with sexual organs and legs which are commonly fetishized."

How a gas pump knows when my gas tank is full
|
[
"[From Wikipedia](_URL_0_): > Most modern pumps have an auto cut-off feature that stops the flow when the tank is full. This is done with a second tube, the sensing tube, that runs from just inside the mouth of the nozzle up to a Venturi pump in the pump handle. A mechanical valve in the pump handle detects this change of pressure and closes, preventing the flow of fuel."
] |
[
"There are two reasons. The older reason is that there is a very small chance that you could ignite the gas fumes with a running engine. The newer reason is that modern gas tanks are pressurized while the engine is running. If you leave the gas cap open while it's running, the sensors will think there's something wrong with the pressurization and turn on the check engine light."

Why are American right wing politicians and citizens so adamant about denying climate change?

Some of these policy changes will probably decrease the amount of fossil fuels Americans consume, and others will probably require significant changes to cars that are sold. 3. These changes will cost oil/coal/gas companies a lot of business, and impose big costs on car manufacturers. 4. Companies that stand to lose money by these changes will pay money to politicians and \"experts\" to deny that there is a problem, thus preventing Step 1."

What led to the "Top 1%" economic gap? And compared to how the general population perceives it, what is the actual economic spread? Is the government doing anything about this?
|
[
"This is not a new phenomenon. The [power curve](_URL_1_) has shown up in economics and various other disciplines again and again. This was first analyzed in a scholarly context by Vilfredo Pareto, who in 1896 noted that [80% of the land in Italy was owned by 20% of the population.](_URL_2_) Research and simulations suggest that this inequality arises naturally in a free market system, and is not necessarily due to corruption or conspiracy (though those could potentially amplify the effect). You can draw a line arbitrarily at the 20% mark, as Pareto did, or at the 1% mark, as the Occupy movement does, but it can be helpful to keep [the entire curve](_URL_0_) in mind. Edit: Better image of income curve"
] |
[
"Not unprecedented, but historically very high. By metrics like the Gini index the US is seeing levels of inequality not seen since the 1930's. It's worth noting that, from the very wide historical perspective, the relatively low levels of inequality that occurred starting in the late 40's are the exception and not the norm."

What is the difference between asthma and bronchitis?
|
[
"Symptom wise they are pretty similar. From a health care professionals standpoint, bronchitis would be more acute and caused by an infection or such (unless it's chronic bronchitis, which is confusing) and asthma would be a chronic condition. Physiologically, bronchitis and asthma both have inflammation involved but asthma mostly involves the tightening of the muscles as well, which is why inhalers are used which relaxes the muscles in the lungs. Bronchitis' symptoms are more from the massive inflammation which makes the airways more constricted. The symptoms are very similar cause it's the same organ being affected, but the details of why the organ is malfunctioning are a bit different...unless you have asthmatic bronchitis which has the best of both worlds. Like for bronchitis, taking a beta - blocker like Albuterol(inhaler) won't be as effective since beta - blockers relax muscle contraction."

[
"> The sign is first attested in British, American, Canadian, Mexican and other Spanish American business correspondence in the 1770s, referring to the Spanish American peso,[1][2] also known as \"Spanish dollar\" or \"piece of eight\" in British North America, which provided the model for the currency that the United States later adopted in 1785 and the larger coins of the new Spanish American republics such as the Mexican peso, Peruvian eight-real and Bolivian eight-sol coins. > > The best documented explanation reveals that the sign evolved out of the Spanish and Spanish American scribal abbreviation \"pˢ\" for pesos. A study of late eighteenth- and early nineteenth-century manuscripts shows that the s gradually came to be written over the p developing a close equivalent to the \"$\" mark.[3][4][5][6][7] A variation, though less plausible, of this hypothese derives the sign from a combination of the Greek character \"psi\" (ψ) and \"S\".[8] _URL_0_"

Why do people have such naturally fragile feet (requiring shoes) when other animals do not.

"We don't have naturally fragile feet. Most of us have unnaturally fragile feet because of the invention of footwear."

"Sometimes enough mutations occur such that something happens in the population. Doesn't have to be meaningful; evolution does not \"think\". Same as why you still have an appendix even though you don't use it. Or why we we don't have keen senses of smell like some of our mammalian cousins. We still retain the tailbone though, but for those who have it exceptionally pronounced in our modern world, they try to correct it with surgery. Otherwise, they can't sit properly on chairs - the \"tail\" ain't got any advantages for them without the ability of its control."
