What is the connection between Thai and Chinese?
|
Regarding the cultural closeness of China and Thailand, as [this Wikipedia article] notes, a significant portion of Thai people are ethnic Chinese, and they are especially influential in business and politics. So a Thai immigrant to the U.S. could very well be a third-generation Chinese, and if that person were to start a Thai restaurant, adding Chinese to the menu would be very easy, just consult family recipes handed down from China. I truthfully think the reason you see them together is simpler, though. Much of Thai cuisine does in fact appear similar to southern Chinese cuisine : stir-fried meat and vegetables with lots of seasoning and chili peppers. And the average American wouldn't know the difference, so the restaurant can just make food that's kind of Chinese, change one ingredient, and call it kind of Thai. I used to live in Seattle, and I never saw any mixed Thai/Chinese restaurants. Seattleites do know the difference :)

Why is 1080p advertised as "full hd" when there are much higher resolutions?
|
Because 1080p is what is considered high definition. 4k is considered Ultra HD. It's just a term used.

How did Oasis become so popular in the'90s, and why aren't they as Iconic as Nirvana?
|
They had catchy, well written tunes . for one album. Their follow up albums got worse and worse and the Gallagher brothers were notorious for not getting along with others or even each other. They even fought on stage. What they were not, however, is ground breaking. They sounded like an update of the Beatles. Nirvana, on the other hand, were original. They produced music unlike anything else, over multiple albums. Also, there is something about dying young that tends to make musicians iconic.

Why do we laugh when being tickled when it's not enjoyable whatsoever?
|
As with most things biological, there is a tremendous amount of guess-work required to come up with a meaningful answer. There are many theories as to why we are ticklish and why we respond the way we do to it. The most compelling to me is the theory that tickling is related to play-fighting. The young of many social animals participate in play fighting where they will attack each other without the intent of causing serious harm. The human behavior of tickling seems to map very well to this, forcing the person being attacked to respond in a way which appears to be happy, and thus not distressing to the attacker. Children generally like some amount of tickling, but this fades over time at about the same time that 'play' of this sort gives way to other interactions.In functionality terms a laugh is not much different than a scream. Being tickled, much like being stabbed, produces and overload of stimulation to our nervous system. Our bodies perceive it as potentially dangerous, so we laugh/scream/make loud recognizably human noises to alert other humans around us to warn them/beg for their assistance inadvertently.

Does the car A.C. Use gas or electric to run, and how does it affect gas mileage specifically?
|
It doesn't directly use gas *or* electric. There's a pulley in the front of the engine. The air conditioning is turned by a belt that connects it to the pulley. When the air conditioning is switched on, it's pretty difficult to turn the air conditioning unit. And since this unit is connected to the engine by the belt, the engine has to do the work of turning the air conditioning. It gives the engine more load. This is similar to, for example, going uphill - another situation which puts the engine under more load. Either the engine will slow down, or you need to press the accelerator more and use more gas to maintain your speed.

Why we need to become unconscious in order to sleep?
|
There are a few animals that are capable of remaining conscious while sleeping, such as dolphins. This is a phenomenon known as [unihemispheric sleep], in which one half of the brain is sleeping at a given time. As to why humans did not evolve to be unihemispheric sleepers, it is likely that the requirements to do so would detract from our other abilities. Our brains are set up in a way that the activation of both the left and right hemispheres are required to perform most tasks. Patients who have undergone a [corpus callosotomy], a surgical procedure that severs the connection between these two halfs, often experience difficulties with tasks that require synchronization of both sides of the body . So likely, even if humans could become unihemispheric sleepers, we would not be able to perform any useful tasks. If we do want to be unihemispheric sleepers while keeping all of our current functionality, we would need redundant areas of the brain, which would be a big investment. From an evolutionary standpoint, unihemispheric sleep is most useful to animals that must be constantly on the move and are capable of maintaining this constant physical activity. Humans have no such requirements , nor the ability to do so . Therefore, our brains changed to increase our cognitive abilities, rather than our sleeping abilities.An important detail which most commenters are apparently unaware of: You are still conscious while sleeping. Sleep is considered to be a state of altered consciousness, not unconsciousness. This is because you can still respond to stimuli while asleep, and wake up if necessary. In other words, everything is working normally while you're asleep. If you're unconscious, that means something is NOT working normally. Things that should wake you up aren't waking you up. Unconsciousness is a sign of something seriously wrong, e.g. brain injury, seizure, alcohol poisoning.

How do loading bars know how far along a download is?
|
When you begin a download, it creates a "box" that says there is a specific amount space that the file will be contained in. As pieces in the box fill in, the box says "hey, I currently have been filled with X number of the Y required pieces."

Why do bands bring have their own speakers and amplifiers if everything is just run through the arena's PA system?
|
Like their guitar amps and stuff? A guitar amp does a whole lot more to influence the actual sound and tone than the PA. A guitarist's amp is pretty integral to his whole sound, so he'll want it to be consistent, and he'll want control over it. Then the venue will put a mic on his amp to connect it to the PA.

In space, it always seems that we are shown traveling on a 2D plane. What happens if you leave Earth and go straight "Up" or "Down"?
|
Our planets are all mostly on the same plane, which is nicely convenient for illustration purposes. If you go any other direction, it's pretty darn empty. And it will take a while to run into the [Oort cloud]. Beyond that is way more empty before another solar system.Everything. Everything is out there. First, let's explain about the solar system. There is a very good reason that the planets are lined up so well. The planets and asteroids around our sun started out as a huge dust cloud that was swirling around the sun. Over a very, very, VERY long time, the dust clumped up and accumulated into the bodies we have in the solar system today. Since the dust cloud was all swirling around one way, the planets are, too. Now, we get to what happens if we travel up or down from the "disc" of the solar system. What's there is the rest of the universe. See, like the planets, our solar system is moving along in our galaxy, which is just a huge cluster of stars. The galaxies themselves are also moving around within the universe. So, what you'll find if you move straight up or down from the plane of our solar system really depends on when you go and how quickly you'll move. For the most part, you'll find a whole lot of nothing. That's just because the universe is so incredibly, indescribably big. However, you'll also run into different galaxies, nebulae , black holes, comets, all of the things that are out there. [here] is a good picture of our galaxy, and our solar system's place in it. The solar system faces about 60 degrees up from the center of the galaxy ), so you would wind up leaving the galaxy pretty quickly. From there, who knows what you'll come across. Eventually, if you go far enough, you will likely see every type of thing there is to see. I hope this answers your question.

Why is the ocean water so clear in places like the Caribbean but not at US beaches?
|
Tropical waters like those in the Caribbean are warm, clear, and completely devoid of nutrients. This is why life clusters around reefs, a lot of creatures eat the plankton and algae that grows on the coral, they provide food for the area The waters up north are cold, dark, dirty, and full of nutrients! The darkness is partially from dirt/mud but a large part is all the algae, plankton, and krill. These nutrient rich waters support a wide variety of animals and many animals will go to these dark waters to feed and fatten up during the summer and then return to the warm clear waters to give birth and raise their young', "More complicated than just contaminants. Taking the Pacific into account, for example, it's often a cold water/warm water difference. Santa Cruz has pretty murky water partially because cold water carries a bigger bioload, where most water in Hawaii is pretty damn clear", 'I think that [this] is the perfect example of why. /u/mmmmmmBacon12345 pretty much summarized it though. Reefs make up a very small percentage of the total ocean but it is the most bio-diverse. This is because the ecosystem is self supporting and many ocean creatures come from the deeper waters to hunt there. The colder oceans on the other hand are the only waters that can handle the larger predators and mammals such as the whale, i.e. krill swarms and vast plankton and algae growth. Edit: sorry, I screwed up my formatting. Skip to 21:45 to listen the exact portion I was referencing about the whales, no food.I don't think you've very familiar with the beautiful beaches the Florida panhandle has to offer. I'd compare Pensacola Beach with many of the beaches I've been to in the Caribbean. [_URL_2_] Sugar white sand and clear emerald water looks pretty damned nice.

What makes someone a "light sleeper" vs a "heavy sleeper" and are there ways to change it around?
|
It's just a matter of habit. This is why you're supposed to have plenty of loud noises while your baby is sleeping, so it gets used to those noises and you don't have to worry about waking it. These habits are started as a baby by your parents, and they are extremely difficult - but not impossible - to change, once you're older. To go from heavy sleeper to light sleeper, you must sleep in pristine, silent locations for probably several months to get your subconscious mind to get used to the silence. To go from light to heavy, sleep with a quiet, but random sound playing, first, such as a TV on very low volume. Over the course of weeks, slowly increase the volume and graduate from calming things like music up to more chaotic things like conversation and eventually something with sudden noises, like an action movie. Eventually, your subconscious mind will learn that random noises are going to happen throughout the night, and it will just ignore them.

Why have newspaper comics gotten so abysmal these days?
|
Several factors are at play. First, you're older, so you've developed a taste. You might recall loving Garfield as a kid, but now you read recent strips and it's dull and bland. But if you went back and read strips that were published when you were a child, you would find them equally dull. Second, the authors change over time. They might come to view their comics as a metaphorical prison for their imagination. They might develop some sort of mental deterioration, as with Terry Pratchett. Finally, external conditions might change that reduce their ability to do their work, as with Tom Lehrer .

How is it that I get so car sick when I try to read or write in the car when I'm otherwise fine?
|
Reading and writing requires intense visual focus. Your eyes home in on the paper, and the visual part of your brain kind of stops paying attention to anything in your peripheral vision. However, if you're in a car, your inner ears are telling your brain "hey, I'm moving all over the place". But your eyes are telling your brain "nothing's moving, you're just reading a book". Your brain, receiving these two conflicting pieces of information, decides that it has been poisoned and makes you headachey/nauseous so you can vomit the poison back up. True Story.You have fluid in your ears that is your sense of balance, if your trying to read or write your eyes and other senses are focused on the task at hand, and not tell your brain that you're moving. But your inner ear fluid knows you are moving, and is telling your brain such. This disconnect between your senses confused your brain and causes nausea.

Why is cheese sometimes crunchy/gritty? And what causes that texture?
|
The crunchiness is caused by crystals of various substances that form as the cheese dries. They start out dissolved in water in the cheese, but as the water evaporates, they start to crystallize. Usually, the crystals are made of calcium lactate. But sometimes, for some cheeses, there are crystals of amino acids like tyrosine, leucine, or isoleucine. Fun fact: tyrosine is named after cheese. *Tyros* is Greek for cheese. Tyrosine was first discovered in the protein casein, found in cheese, by Justus von Liebig.

If a MLB pitcher were to hit a player in the head, and that player have life suffering injuries, would the pitcher be in trouble?

Unless it was intentional, no. All the players signed legal waivers when they sign their contractsOnly if intentional. By playing on the field you are accepting the risk of injury.
|
If a joint cracking is a result of gases in the joint popping, how can I crack the same joint multiple times?
|
imagine you have a balloon and cracking a joint is like opening the balloons mouth for 1 second. If you have more fluid in your joints than one moment of release from a single crack, more will come out on subsequent ones. you may notice how they get progressively less powerful as the crack count continuously goes up', "The gas doesn't go anywhere, it just comes out of solution. Over time, the gas will dissolve back into your synovial fluid. That's why you can't pop the same joint quickly, but you can after a while.
|
Why or how do fires make sound? More specifically 'roar' ?
|
Hot air rises, and the fire heats the surrounding air unevenly, causing increased turbulent air flow around the fire that we can hear as soundThe flames heat the air near it, causing it to expand, then as that air leaves more air comes in to be heated, causing waves of pressure I.e sound
|
The phases of the moon and their rise and set times.
|
The moon orbits and rotates around the earth in the same way as the earth orbits and rotates around the sun. Because the moon orbits the earth at a different rate that the earth rotates it causes the moon to rise and set at different times of the day The phases of the moon are also due to its orbit. The part of the moon that you see is being illuminated by the sun. As the moon orbits earth, the side that is facing the earth stays the same but the side facing the sun changes and completes one full cycle approximately every month.

Is there any Virus which infects Apple products?Why is there such a big problem with windows and hardly any problem with the mac when it comes to bugs?
|
Yes, there has been malware for Apple products including OSX. Windows gets targeted more because it has a far larger market share. I haven't had significantly more bugs on a Windows device than I have on OSX. I haven't seen a BSoD since XP was the latest Windows OS, but I did see a kernel panic on OSX just a few months ago.

Do birds stop for rests after flying for long periods of time?
|
It depends on the bird. Most birds do stop to rest, but birds like swifts, terns, and albatrosses can stay in the air for weeks or months at a time, usually by gliding on air currents. One benefit is that lets them conserve energy.
|
Why auto makers dropped the frameless doors?
|
Because they really didn't work too well. It was too hard to build a seal between the car frame and the glass, that worked well when closing the door, while allowing the window to slide up and down. Because you couldn't hold the glass in a channel, the window gets pulled away from the seal at high speed, unless you design it to push tightly against the seal, which makes the door hard to close and makes the window-winder mechanism stiff. The door-window seal has to do different things to the door-car seal. Trying to make one seal do both meant that both things were done poorly.

is it true that if one sits too close to a television it will affect your vision after a certain amount time?
|
It MAY cause eye strain which could be a temporary annoyance, or cause a headache. But no long term damage can/will come of it. Simply put, your parents said that because if you were to close to the TV, it makes it harder for others to see.

Australia is a relatively new country which was settled by the British so...where the bloody hell does the accent come from?
|
It doesn't take long for an accent to change! *We* even have different accents from our own parents. Or maybe you can tell more easily from your grandparents. My grandparents sound much more \'plum\' than I do. The children of the first fleet would have had a different sound from their parents, who were a unique mix of different British accents. Probably the children heard the adults, who came from different areas, and subconsciously chose bits and pieces from different adults, creating the first Australian accent. Sometimes Australian TV replays news segments from the 1930's, 40's, 50's, 60's and 70's - each generation sounds slightly different. Recall "Skippy" in black and white, or an old "Tip Top" commercial, or the Prime Ministers in the first half of the 20th century - the further back you go, the more the accent sounds like the Queen - or like an old fashioned Scot or IrishmanGroups in isolation develop their own accents over time. Its the same reason the US has about a dozen different dialects, yet everyone speaks English for the most part. It starts with basic words, some lose their relevance in different environments, some new words need to be added to account for new things, and over time it shifts the language, and further isolation leads to more shorthand speak and slang, which affects dialect.As well as the other good answers - accents change much quicker than you perhaps realise. Think how differently you speak to your grandparents. Your grandchildren will speak very differently to you. Over just a few generations, your grandparents and grandchildren will speak so differently from each other that they'd probably find each others' speech quite odd - or at the very least, quite different to their own.

Why do low fuel prices have a negative long term effect?
|
They don't. ..although they can have. One of the things you need to remember with economics, is that very few things "do X". Economies as a system are too complicated for such easy conclusions. In this case however: The rise of fuel prices tends to drive inflation , a good that costs $1 today could cost $0.9 tomorrow; so suddenly the money you already have starts increasing in value, which is an incentive for you to hold on to it. The longer you keep it, the more valuable it becomes. As such consumption of goods and investment in future technologies drops off. Since our economies depend on private consumption & industries investing into research & development, lower fuel prices could lead to a drop in consumption. The counterargument is that lower fuel prices would lead to more consumption, because everything is cheaper & people have more money left over. Which of those two is more true than the other at any given moment depends on dozens if not hundred of other factors . The middle line is that you 'd want low inflation , while avoiding deflation; but most of all keeping everything more or less stable. No one likes disrupting effects in their macroeconomy, since there are no cookie-cutter solutions.It's not the effect of the low fuel prices, it's the effect of other things are shown by low fuel prices that are causing worries. Analysts who see concerns in the low fuel prices believe that the prices are indicative of demand for fuel dropping, which would strongly suggest poor economic activity .

What are/were qualudes? What were they originally intended for? What did the effect feel like? How they used?
|
Well, since they are impossible to find these days, no harm in discussing what they were about. They were originally a sleep aid, prescribed to those who can't fall asleep or sleep through the night . People pretty quickly found out that if you resist the urge to sleep, you were hit with a pretty powerful high. The drug itself is a depressant and a muscle relaxer . As you might guess, the effect is pretty much a combination of the two . You're partially numb , have poor coordination/motor control/reactions. You feel dizzy, are more easily sexually aroused, and may have slurred speech-quite like alcohol. When too much is taken, the effects are like modern barbituates-delirium, convulsions, vomiting, and death through cardiac or respiratory arrest . They were used in the same context as alcohol or other barbituates. Some used it for fun, and would go out socially or dance . Others would use it for relaxation or "tuning out", much like modern barbituates. At this point, they're gone. Production officially stopped decades ago after controversy, and even underground production essentially stopped many years ago after popularity dropped.

How can birds sit on electricity cables and not be electrocuted?
|
Electricity will always seek to flow through the path of least resistance. If it can flow at all, it will go through the conductor that is lowest in resistance to the flow. When a bird perches on an electrical wire, there's no change in the bird's electrical status- it offers no easier path for electricity to flow, because it's already flowing through the wire, which is *far* lower in resistance than a bird is. If a large bird or other animal were to touch two wires or one wire and the ground at the same time, then it would create a path between two different electrical states , and then electricity would flow between those two wires through the animal. Probably very briefly, as the animal would die or burn up almost immediately. Editing to add: Almost no electrical cables on power poles are insulated because it costs more, the insulation can crack and wear away, and it serves no purpose other than to increase expense and weight. Only in some specific circumstances are overhead power lines insulated, and it's not common.

How do they make old 70s and 80s movies in high definition when it didn't exist back then?
|
Film is a very high quality medium capable of storing images very high resolutions. The master prints of those films are still around and are used to create HD copies. Back then, scans of the films were taken at relatively low resolutions because VHS tapes were the standard medium for distribution. VHS tapes are low quality and the TVs people would view them on were low quality. Nowadays, much higher quality mediums are available for redistribution, so the films are being rescanned at more appropriate resolutionsFilms don't have a resolution per se but each frame does have a physical size. A 35mm "Cinematography" frame is about 18mmX24mm. 16mm is about 10mmX7.5mm Super 8 film is about 4mmX6mm. Each film stock has a certian granularity and contrast Assuming you had three pieces of film all shot with the same stock but with three different formats, the 35mm would have the smallest grains per frame. So while you could scan a super 8 film at 4K it would look very grainy compared to a 35mm film scanned at 4K. The point is depending on the era and the format and the film stock certain old films will be rescanned for modern HD formats with baying degrees of success. You can also "reduce grain" during the scan or digitally. When you see an old film like evil dead and it has "that look" it's because of th grain and contrast that comes with a smaller format super 8 is even more grainy and more contrasty.

How healthy are probiotics for you? Do they help with weight loss?
|
Probiotic refers to food that contains "healthy" or "beneficial" bacteria. Our intestines are loaded with bacteria that help us digest food. Probiotics contain some of those bacteria. They are generally recommended for people who are on long term antibiotic therapy, among other things, as those people will have a lower population of good bacteria in their gut. So no, probiotics have very little if any effect on weight.

What is syndication on TV?
|
Syndication" is essentially a market for programs to be sold to TV stations, to fill out their schedule]. For the most part, at least for broadcast TV, \'primetime\' and morning news shows are the only programming produced exclusively by a network for broadcast on their own channel. Everything else is syndicated programming purchased by the local affiliate or regional association to fill timeslots. So, shows like Jeopardy!, Xena Warrior Princess, and a lot of shows that were cancelled after the first season but continued to make episodes are straight-up syndicated; they are produced independently, and channels buy the rights to broadcast the shows. There's no direct relation to the channels, so in one city it might be shown on the Fox channel, in another on CW, in another on the weird local-access channel that usually just broadcasts church services, etc. Now, when a popular first-run non-syndicated program gets enough seasons under its belt, they take the older episodes, package them up, and sell them on the same syndication market as Xena Warrior Princess. The TV stations that need to fill out their schedule now have the opportunity to buy older episodes of popular shows to broadcast as well, because it comes with a pre-built audience -- they know people like watching *Everybody Loves Raymond*, but the indie detective police procedural might need some time to find an audience. Also, the original producers of the channel have an extra money-making outlet for new episodes, especially since a station already paying for seasons 1 through 3 are definitely going to buy season 4 when it comes available for rebroadcast. This is also why a lot of actor's contracts get up for renewal about the time syndication becomes available: more seasons means more revenue, and is thus a negotiating factorIt means a station has paid a very hefty sum for the rights to broadcast the show for a number of years. Everyone involved in producing or acting in the show gets a huge payday.

What exactly is the Dial-up sound?
|
They're doing a few things: * Figuring out which protocols each modem is capable of, and selecting the best one that they both can handle. * Sending some commands to the telephone network that switch it to a mode more useful for modems than talking. * Measuring the qualities of the telephone connection. * Figuring out what the highest speed they can use is. _URL_0_", 'When modern computers were first invented, they needed a way to allow computers in homes and businesses to communicate between each other. Originally, the best way to do this was a null-modem cable or other some such mechanism which required custom wiring. There was no way to do it at a distance because there were no global digital networks that could be accessed easily/cheaply. There was, however an analog network which could be -- the telephone. A device was invented which could convert digital signals into beeps, buzzes, and clicks which can be easily transmitted over the phone where a similar device would convert them reliably back into the digital equivalent. What you're hearing is the speaker on the modem playing the first 30 - 60 seconds of audio from the phone line. It's configured to play this sound because, occasionally, somebody would enter a phone number incorrectly and get a person instead of another modem. You 'd be able to hear them speaking. The modem, however, being not the smartest of devices, would simply report "connection failed" to the computer which would cause it to try again. The speaker was there to prevent a computer from harassing some poor person with a similar phone number to a BBS or ISP.

When a relative gets into an accident, how do emergency services notify you?
|
Depending on the circumstances, there are a number of ways next of kin are notified of an accident: - if the accident is fatal, all efforts are made by the police to locate the next of kin and notify them in person. This allows for support and victim services to be made immediately available. This also ensures that the person being notified is safe and doesn't do anything to hurt themselves out of grief. - if the next of kin lives in another city/state/country then the local police agency is contacted and asked to assist in making the notification. - if the accident is not fatal than typically social workers at the hospital will contact the next of kin by phone, advise them of the accident, and ask them to come to the hospital. Sometimes the police will assist with this type of notification if needed. Source: I've done it many times and it sucks.

Why can English speakers efficiently communicate with most other English speakers (regardless of dialect) but a lot of Mandarin speakers can't communicate likewise between the various dialects of Mandarin nearly as efficiently?
|
Because there is no clear distinction between 'language' and 'dialect'. An important aspect of differentiating between a dialect and a language is mutual intelligibility. If two people who speak the different dialects cannot understand each other, then they speak different languages. However, in the real world languages don't exist in isolation. They are connected to culture, history and religion, and and all these aspects are also important in whether a dialect gets to be called its own language. For example, speakers of Hindi and Urdu can easily communicate with each other. In fact the Hindi pop culture produced in India is consumed by Urdu speakers in Pakistan and vice versa. However, because of historical and religious reasons, the speakers of Hindi and Urdu like to consider them different languages. The reverse is true for Arabic. An arabic speaker from Western Africa and one from Saudia Arabia would have difficulty understanding each other. But because of cultural and religious reasons, both would claim they speak Arabic. So why are different dialects of Chinese not mutually intelligible. Because while they are considered the same language due to historical and cultural reasons, they are as varied as the Romance languages in Europe. Wikipedia states: > The varieties of Chinese are usually described by native speakers as dialects of a single Chinese language, but linguists note that they are as diverse as a language family. The internal diversity of Chinese has been likened to that of the Romance languages, but may be even more varied

Why do people feel a dull ache in their forehead when an object (like a pen or finger) is brought very near to, but without touching, the point between their eyebrows?
|
I get the same sensation when something comes close to the area between my eyebrows. It has nothing to do with eye movement or mystisism. I cannot explain why but i can feel a slight pressure when an object is close. I have wondered about this myself.I'm kicking myself because I can't find the source, but I read an article several years ago that the theory behind this is that it's a primitive thing left over from our lizard brains and predator/prey instincts. It was advantageous to be able to sense when someone or something was close to you. I personally get the weird feeling of pressure if any part of my body is too close to something else without touching it.

Since I'm not a Nielsen family, does pirating a show basically have the same effect as watching it on live TV?
|
With respect to TV ratings, if you're not participating in any special Nielsen Families program, then pirating would be effectively the same as watching the TV program live via antenna or via a passive cable/satellite tuner . There are, however, cable/satellite TV set-top boxes that can technically report back to the television service provider what channels you are watching. Whether your television service provider actually collects this information and/or shares it with other parties for measuring ratings, that's a whole different story But certainly in terms of passive tuners , then there is no way they are collecting information about your viewership of the program and thus pirating would not affect the ratings.

How can gas stations charge 9/10 of a penny, when no such denomination exists?

Since there is no such denomination, they "do it" by rounding to the nearest penny. When you multiply any amount of gas by any price, you always get something that has to be rounded off. It's their way of turning 9 cents into a dime, 99 cents into a dollar. That also gets them a tiny bit more money than if they didn't use that 9/10 of a penny in the price. I run into people all the time who think $2.599 is two dollars and fifty-nine cents. The ruse works.Gasoline is sold by volume. That means if you bought EXACTLY ten gallons at $1.89^9 you would pay $18.99. But people don't buy or need to buy EXACTLY one gallon of gas. They either fill the tank or put in say $10. So the price lets you know how much you are paying and you can round up or down as you see fit.

Why do spicy foods affect some people more than others?
|
From personal experience, it's how used to spicy food you are. The experience I've had involves home made curry; one my dad made that he considered to not be spicy at all, I agreed, was way too hot for friends I shared it with. I imagine it's tolerance. The more spice you eat, the more you body is used to the level.

Why does society view the exposure of the female chest so differently from that of a man's? Why do women have to cover and men don't?
|
In New York State wherever a man can legally be topless, so can a woman.Societies will always view a man's bare chest differently than a woman's bare chest, because breasts are a secondary sex characteristic that men don't have. How exactly that plays out in a particular culture at a particular time will change, but it will never be an apples-to-apples comparison due to sexual dimorphism.

Why do homegrown plants need constant attention such as water or they will die, while wild plants are left alone and flourish?
|
Wild plants die all the time. The ones you see are the few that lived - natural selection. They are outdoor so they get water from rainfall. Indoor plants are often from another region. They are constantly at "room temperature", something that no plant is naturally accustomed to, so we often get plants from climates that have milder warm weather or plants that are especially hardy. They must be watered because, being indoors, they get no water from nature. In the wild, if the plant dies who cares, there are likely others nearby that live on. In a house, you have a single plant and want to make sure it stays alive. Also, plenty of houseplants require water and care like once a week. That is not "constant attention" by any stretch of the imagination1) Wild plants die all the time, you just do not notice them. 2) Homegrown plants are generally not native to your climate. As such they need more tending because they are evolved for a different environment and need you to simulate that environment to keep them alive.

Why are Hazmat suits so big and bulky? How come they can't make them smaller and slimmer?
|
They are both positive pressure and most contain a SCUBA apparatus. This alone results in a system that isn't small. Additionally, the material the suit is made from should be chemical and puncture resistant, this adds thickness. Additional layers may be worn underneath depending on the situation encountered.They are a few sizes fits all and they are positive pressure suits so if one gets a hole, air flows out.

Why are actors/directors/crews not employees of major studios (or are they)?
|
Movie studios used to operate this way many decades ago. It was referred to as the star system. The decline of this method of operating came about largely because studios became notorious for exploiting actors and heavily restricting or controlling their careers. The system also tended to favour the development of a star's personal image, rather than focus on the quality of the acting. People in the entertainment industry still enter into contracts for all sorts of projects, however the goal of most artists is generally to retain creative control over their careers and being signed to lengthy contracts with studios obviously limits that.

why is it easier to balance on a bicycle when moving than when standing still?
|
I actually did a little research project on this a few years ago. There are two main sources of tilting: the moment of force from gravity, and the moment of force from the centripetal force.What you have learned subconciously is how to use your steering weel as input to use the centripetal force to balance out what the gravitational force does. Additionally, there are some facets that make it easier for you. Geometry can be optimised so the bike has some self steering properties [theres a lot that can be said about this and I'm not going into it all]. When it starts tilting due to gravity the steering wheel will automatically turn to generate a centripetally induced tilt. Note that this results in an oscillation and this can be clearly seen when you push a bike without a rider, it will go in a straight line initially, then start oscillation with an ever increasing amplitude and eventually crash. Also, gyroscopic effects of the wheels increase stability . Common misconceptions are that you balance by leaning while driving, or pushing on the footpegs/pedals or steering wheel. Also interesting to note its very counter-intuitive. To go left you actually steer right first. For instance, R/C motorcycles have a servo that pulls/pushes on the steerig wheel but the servo controls are reversed: steering to the left on the controller will put pressure on the wheel to steer to the right. To finally answer your question: without forward speed you cannot create the centripetal force. [edit]: Sorry, I got a bit carried away and made it too technical, I don't frequent ELI5 I just saw a subject I know a lot about and wanted to help /u/brierrat did a better job perhaps.

Why do deeply religious people badmouth other religions?
|
From their perspective, other religions *are* evil. If you believe your immortal soul goes to heaven you believe the right stuff, and goes to hell if you believe the wrong stuff, other religions are Satan's trick to try to lead you into damnation. To you, they are literally the worst thing in the world.

When you download a newly aired episode of a show, where/who does that file come from?
|
Someone runs their cable box's output into a computer which captures the video stream and saves it as a video file. That is then uploaded. The capture and creation of video files isn't unique to media companies you know.

Why are the directions "left" and "right" associated with liberal and conservative political philosophies?
|
It comes from the French Revolution when people loyal to religion and the king would gather to the right of the president of the National Assembly while supporters of the revolution would gather on the left. The right thus became associated with traditionalism and conservatism while the left with equality and revolution.> We began to recognize each other: those who were loyal to religion and the king took up positions to the right of the chair so as to avoid the shouts, oaths, and indecencies that enjoyed free rein in the opposing camp. Baron de Gauville, speaking about the French National Assembly in 1789 Even in 1791 after the Legislative Assembly replaced the National Assembly as the governing body of the French Republic the defenders of the Ancien Regime sat to the speaker's right and the innovateurs sat to the left. By the Third Republic the political parties were called Republican Left, Center Right, Center Left, Extreme Left, and Radical Left. These terms became popular among English speakers during the Spanish Civil War when describing Nationalists and Republicans.

why is there a feeling of total disgust for men after they finish masturbating...and what causes it
|
Your mind pretty much goes from a high state of pleasure to a state of reason in a matter of seconds ', "Masturbation itself doesn't cause disgust. But often times porn includes things that are disgusting. Rimming, girls taking it in the ass then mouth, ugly guys gang-banging a girl gross! [But if you're aroused, the arousal trumps disgust]. Guys can get off to porn they might otherwise find gross because their arousal tones down the feeling of disgust. When they come, the arousal is gone, and then - IF the porn is something they might find gross - the feeling of disgust can surface.

Differences between IVR, MMP and the American voting system.
|
America has FPTP also. Basically, whoever gets the most votes wins. In some cases they require a majority. Then they take the top two and have a runoff. The problem with this is as follows. Let's say we have three candidates, Alice, Bob, and Charlie. 60% of people like Alice or Bob, but hate Charlie. The other 40% like Charlie but hate Alice and Bob. Voting day comes, and Alice gets 25%, Bob gets 35%, Charlie gets 40% and wins. Now 60% of people are mad. IRV means you would rank your options instead and require a majority. In the example above, Since Alice had the fewest votes, she drops out, and people who voted for Alice have their second choice get their vote. Now the votes are 60% Bob and 40% Charlie. The majority of people are happy with this. MMP I am not super familiar with, but this is how I understand it. Sometimes, It's more important what party someone is a member of than who they are. Say, all the blues always vote the same way, and all the reds vote the same way. You have a district that is 55% blues and 45% reds, and they are electing 10 representatives. With MMP, you vote for the party, and there are 6 blues elected and 4 reds. Without it, one popular blue could get 55% of the votes, but the 45% reds vote 5% each for 9 red candidates. Then we've elected 1 blue and 9 reds from a district that is 60% blue. You can see why the blues don't want this.

How do nations determine their currency value?
|
Most currencies are not regulated in the way you say, countries do not set the values of their currency in international trade themselves. This was not always the case , but now, most currencies are floated on an exchange, the Foreign Exchange Market, where the value of each currency is determined by market demandA country doesn't actually value its currency, the market does based on a wide variety of factors. The country can control the supply of its own currency assuming it operates on a fiat basis . What tends to happen is if countries print too much of their own money then other countries value it less. There are exceptions to all of the things I 've said. But that's the ELI5 versionThere's nothing to stop any country from valuing their currency at anything they want to. Within the scope of control of the country. If your country doesn't need anything from the outside, and doesn't allow anyone to leave, then you can set the currency to anything you want. There aren't really any countries that fit the bill of not needing anything from the outside. If you need to actually interact with other countries, then you need to let your currency "float". Which is to say that you need to allow the currency to trade against other currencies, which will send your currency to it's \'normal\' value.

How are urls created, and also how are they made so they dont match another url?
|
each url links to exactly one ip address . this ip address determines the webserver which will serve the webpage. [server].[domain].[top level domain]/[sub directory] default server is usually www. although the domain host can choose to have others for specific pages within the same domain such as, _URL_2_, _URL_0_, _URL_1_, etc etc. domain is domain, such as reddit, google, microsoft, etc. top level domain. .com = commercial site, org means non profit, net means network, but don't have to follow these guidelines. some specalized ones such as .edu .gov .cn .ru etc are reserved for educational entities, us government, china, russia, etc. sub directories are just directories inside the webserver. most webpages front page are served on the root directory", 'URLs are made of a few components. To make it simple, host, domain, and directory. _URL_4_ for example. Mail is the host. _URL_3_ is the domain. All is the directory. Google, being the owner of _URL_5_ is the only one who can create a URL using that domain. They ensure it is unique. Googles DNS serversin this case is used to create the full URL by defining the host of mail and tying it to a server by ip. The directory of "all" is a folder created on the web server itself.

Why did it take so long for FTC to accuse Vemma of creating a pyramid scheme?
|
Many pyramid schemes masquerade as legitimate MLMs. The structure is identical, so just because it has that kind of structure isn't enough for the government to file charges. They need *evidence* that something illegal is happening.

Why does it feel normal to sit back down in your chair, but if you sit in someone else's it feels warm? Why can't we feel our own butt warms?
|
When you sit in a chair it will change to the temperature of your body. So you wouldn't know the difference because the temperatures would get to the same degree as you currently are. Other people's body may be at a higher temperature at the time so you will notice the difference as the chair would be as warm as the person was.

How do Blimps work?
|
Blimps will have a second gas bag in the envelope that can be filled with air, this increases the density of the helium making the blimp heavier. Helium can also be vented if the blimp needs to descend rapidly. Blimps can also have variable pitch engines that can be pointed up or down - some blimps are slightly heavier than air and need constant engine thrust to maintain altitude

If money or politics were no object, how would we best protect the power grid from a solar storm, EMP or attack?
|
> No matter how remote the possibility, any chance is too high to leave it unprotected. Really? What about a chance smaller than the chance humanity just gets wiped out outright? But to answer your question, burying it underground would protect against just about any currently available form of attack - except you said *zero* risk so we'd have to protect against every possible form of attack, even the ones we don't know about yet, which is impossible. Solar storms, at least, are pretty easy, you just don't run long uninterrupted power lines. Simply putting breakers along the lines would probably do the job of stopping induced current.

Why are people able to get your IP from your Skype name but not from other things?
|
If you've got a direct connection to someone , they can see the IP address you're using. Other things like Facebook aren't a direct connection between users; both people access the server to see what's been posted to it. It's a question of who has access to the information. If I ran a message board, I could allow administrators to see the IP addresses of everyone posting. Or I could publish those next to a post if I wanted to. The people with whom you're speaking are advising you avoid direct connections with people who might want to do your system harm.Most of the comments shutting you down are incorrect, you can use a multitude of methods to find someones ip address without being in a call with them, hell the easiest of methods would involve using a simple website like *WEBSITE EDITED OUT TO AVOID ABUSE* which allows you to find ips based off of ones skype username, as you believed was possible. NO DIRECT COMMUNICATION IS NEEDED AT ALL. ~Might edit out that website in a few mins, we will see.^ Decided to.

Why don't countries apart from the US have manned moon landings?
|
I think the US sent a man to the moon more for national pride than for any practical purpose. JFK declared America's intent to complete this mission in order to send a message to the Soviets and the world that the US was a superior nation. Today, it's less about pride and more about science. It makes no sense to send manned flights, because unmanned flights are cheaper and more versatile, and can do things that humans can't, like stay there for long periods without food.

why our eyes create pink visual stains after we look at strong light?
|
There are multiple ways that our eyes adapt to different light conditions. One of the ways this automatically occurs is due to the way the light receptors in the back of the eye work. In each light receptor cells are molecules called retinal , which are the ones that react with light and eventually cause a signal to be sent to your brain. The act of being hit with a photon of light and activating the signal makes the retinal molecule inactive, and it needs to be reactivated by an enzyme before it can work again. In intense light, all the retinal molecules quickly become inactivated, and very few are available to pick up new light signals. When you return to dark conditions, it takes a while for the retinal molecules to become reactivated, which is why you are somewhat blind for a while until your eyes adjust. The second reason you see stains is because of the way your brain processes visual signals. It quickly adjusts to different light conditions as the new "normal" and picks up contrasting signals as if there is something there, even though it's just the absence of light. When you look at a strong light, then away, it looks like there is a dark spot of the same shape until your brain figures out the new "normal".

How do people hack into an intranet and why do we need anti-virus systems in an intranet?
|
There are a lot of ways someone might "hack into an intranet" but a simple way to understand why something might get through the barriers surrounding an intranet is to consider USB thumb drives. A virus on a thumb drive might easily be introduced within the network even with the strongest of barriers between the internet and intranet.

What is Maoism? Why is Chairman Mao considered a great leader when he caused a lot of deaths?
|
My family is Chinese and my parents grew up during this period and almost everyone in my family and relatives dislikes him for what he had done. My parents are pretty outspoken about their dislike for him and my relatives are still in China but they don't really praise him either. From what my parents told me - they dislike him because my relatives way back when were relatively wealthy, but it is because they had a lot of land and they worked hard on that land, but when Mao came into power, they took his land my relatives had worked hard on and gave it to other people who may not know how to work the land properly and therefore my grandparents and parents grew up in poverty. They had rations for everything from even flour and salt and obviously meat and vegetables, and were hungry all the time, and both my parents had a ton of siblings, so growing up during that period wasn't the easiest. I think they only had dumplings for like Chinese New Year or something, and normally they'd just eat stuff like millet porridge and Sorghum noodles. When they were children they ahd to go to the country and work in the fields before they could go to school. Also, in schools they had to salute chairman mao and basically idolize him - it almost reminds me of Hitler and North Korea in a way. So I guess my point is that there are chinese people who dislike him out there.

Why is there a northern and southern accent in the United States?
|
There isn't *a* southern accent and *a* northern accent. There's a Boston accent, a couple different New York City accents, a Chicago accent that is similar to much of the Midwest, Minnesota has a distinct accent, Kentucky isn't quite the same as Tennessee, North Carolina and South Carolina sound a bit different from each other, East Texas sounds different than West Texas, and let's not forget the millions of Texans whose accents are influenced by the prevalence of the Spanish language in their area. Maine is different than Maryland, Baltimore has a distinct sound among Marylanders, and I'm still leaving many US accents out. People are just different. The reason the different accents exist is the exact same reason different languages exist. When one community is isolated from another for long periods of time, slight changes start to creep into speech patterns. Remember electronically recorded and instantly broadcast speech is a new phenomenon in world history. Even dictionaries are only a couple hundred years old. People are just different, and sometimes when you put hundreds or thousands of miles between two groups with no means of instant communication, they'll come up with different ideas for doing things.Why is this under biology? Anyway, this is due to differing patterns of settlement. The North was settled mostly by religious pilgrims from the more rural regions of southern England, while the South was settled mostly by Scots-Irish settlers and aristocrats. This resulted in the creation of two different accent regions, which spread their influence as the rest of the US was settled Any group left to itself will eventually develop an accent and vocabulary all their own. Due to nationwide TV broadcasts and now the internet, this is fading fast.

Why do antidepressant often have depression as a side-effect?
|
Anti-depressants are a guessing game as far as prescribing them. You're messing with the brain my friend. There's no telling exactly how they'll affect one particular person and how they feel. Having used them, it's hard to tell exactly what feels different sometimes. You think a strange thought that you've never thought before and wonder if it's just you or the drug. Or feel a certain way and can't tell if you actually feel that way, or if the drug makes you feel that way. Crazy stuff.

Why does it always come down to "drink lots of fluids" when you tell the doc you gave the flu?

There's no cure for influenza once you're sick. It's a self-limiting and mild infection that your immune system will fight off, all you have to do is keep your body working long enough for it to do so. That means sleep and fluids.

What's a cellular automaton ?
|
For starters, it's not really an essential part of understanding computing. The idea came about as more of an entertaining thing to do with computers. At best, they're a footnote in the history of computing. Take a grid. Each cell of that grid can either have a thing in it or not. Now, given some rule based on the neighboring cells, you can decide if that cell has a thing in it for the next generation. The original example was [Conway's Game of Life], the rule were fairly simple: 1. A live cell with 1 or 0 live neighbors dies of loneliness.2. A live cell with 2 or 3 live neighbors is happy and survives.3. A live cell with more than 3 live neighbors dies of overcrowding4. A dead cell with exactly 3 live neighbors gets colonized with new life. With these 4 simple rules, it turns out that surprisingly complex patterns can arise. There's a virtually limitless number of different rule sets you can come up with, all of which have different patterns of behavior.

How a "double bounce" or "super bounce" on a trampoline works
|
Fred is going to double bounce George. As George comes down from a jump, Fred jumps in and lands right next to George. Their combined weight and momentum stretch the trampoline tighter than it would with just one of them. At the bottom, Fred hops off to the side, however the trampoline is still stretched very tight. That extra tension propels George higher than he would be able to have gone on his own.

What does 10th Cousin, once removed mean?
|
First cousins have the same grandparents. Second cousins have the same great-grandparents. Third cousins have the same great-great-grandparents. And so on. So 10th cousins have the same great-great-great-great-great-great-great-great-great-grandparents. "Once removed" means that you're of different generations. For example, if Joe is my first cousin, once removed, that means Joe's grandfather is my great-grandfather. Another way to think about it is that if someone is my Nth cousin once removed, then they're Nth cousins with one of my parents. Likewise, an Nth cousin twice removed would be Nth cousins with my grandparents. [Wikipedia has some graphs to help visualize it]', "If they could both go 10 generations back and find a shared ancestor, they'd be 10th cousins. If one has to go back 10 generations, and the other 11, they are 10th cousins once removed.

Why do Jehovah Witnesses not celebrate Holidays?
|
exJW here. We avoided Easter because we celebrate the last supper in form of The Memorial, instead of Jesus' resurrection. As for the rest of the main holidays, we avoided Christmas due to its roots in paganism, Halloween due to its association with the occult, and birthdays because King Herod had John the Baptist beheaded for his birthday. Also, pagan roots.

Why do people work more hours today than we did in the 50s and 60s? What has happened to cause this?
|
I think it includes factors like the erosion of the middle class, stagnation in wage growth, predatory lending and insufficient welfare. I think people are over committed to debt, being paid less in real terms and are scared of losing their jobs partly due to the way the unemployed get treated. Anybody who blames women entering the workforce are missing the point.

Is North Korea a credible threat to the the US? Aren't these the same guys we mock mercilessly?
|
North Korea is not a credible threat to the US. There are a bunch of US military stationed in South Korea who could be in danger if war broke out there. NK has a large but generally poorly equipped and trained army. They could potentially cause a decent sized mess in South Korea in the early days of a war, but they would be pretty quickly defeated. The NK military does not have any reasonable power projection ability. They 've got some missiles, but likely nothing capable of reaching the US, and certainly nothing with that sort of range that has been well tested and could be considered reliable. Any overt military action against the US would pretty much be suicide for the NK government. I guess they could create more mischief via their "cyberwarfare division" or whatever they call their hacker teams. But it's pretty unlikely that they could cause serious problems that way.North Korea is not really a threat to the U.S. itself. North Korea is perhaps a threat to South Korea and Japan, which are U.S. allies. Even then, North Korea would be unlikely to attack them as they'd probably get some sort of reprisal from the U.S. for that.It depends on what you mean by a credible threat. Are they a physical, military, or nuclear threat? No way. But they HAVE demonstrated the ability to cause actual damage by cyberwar and counterfeiting. Both of those really rather rely on them not getting *definitively* caught doing it. The Secret Service has long believed that the ultra-high-quality counterfeit $100 bills known as "super notes" were produced in NK, but we have no proof.Being a credible threat to the US as a nation, a la, a 9/11-style attack or even organized large scale war? Probably not Poorly equipped and in generally poor health, their military is more or less a joke, despite being quite large. They are certainly a credible terrorist threat on the small scale, let's say, on the scale of bombing theaters filled with civilians watching a movie, for example.

If computers have to follow direct commands, how can it choose things at random?
|
Computers usually *can't* choose things at random. Instead, they have algorithms that can generate [psuedo-random numbers]. This often involves seeding the number generator with various "random" factors, such as mouse movements, the current time, and/or the contents of the computer's memory, which are all unlikely to be the same the next time a "random" number is needed. Although, with [special hardware], more-truly-random numbers can be generated. **Edit:** Also, I don't see what this has to do with living things making choices. Your choices are decidedly *not* random. If they were random, they wouldn't be choices. You don't do the mental equivalent of flipping a coin or rolling a die every time you decide something. Rather, you weigh the pros and cons, and reach an informed decision.

It's a learned response. Different languages have different words for "ouch". You expect something to hurt so you go through the learned response.

Why don't bands release instrumental tracks alongside their regular albums?
|
In most cases there just isn't enough demand to justify an instrumental release alongside the standard album. In the rare cases that it does happen there's usually a proven demand for it, either that band or the genre as a whole do well with just instrumental releases.

Why can we digest salad (Leaves etc.) but not grass?
|
Most of grass is made of cellulose and human digestive system is not equipped to extract energy from it. Unlike cows. Some parts of grasses can be eaten, like grains, where the glucose is stored. Leafs have less celluloce and the sugars are stored in a form more suitable for humansMost grasses are high in cellulose, which we cannot digest. Edible leaves are low in cellulose and high in digestibles.

What did they do before eye-glasses? What if people had horrible vision?

What makes a CD an EP and not an LP or album?
|
EP and LP are terms that originated with the technology of vinyl records. An LP is a 12" vinyl record which when played at 33-1/3 rpm gave you ~22 minutes per side -- they were able to stretch that a little bit but not too much. A 'single\' was a 7" vinyl record with a bigger hole in the middle which when played at 45 rpm gave you a single song on each side of 3-5 minutes . An \'EP\' was in the middle. The format varied but often it was a 7" record but played at 33-1/3 RPM instead of 45 RPM so you could fit perhaps 10 minutes on each side. In the industry, the format ceased to matter after a while, an EP became synonymous with a 3-6 song release. Whenever a group is inspired enough to write more than a single and its B-side but not inspired enough to write a full album they could release something in the middle and call it an EP.
|
Does cooling a sealed bottle/can of soda and then letting it come back to room temperature cause it to lose carbonation?
|
No. The sealed bottle or can is much closer to an enclosed system than an open container - it can stay very well carbonated for months. It would be a reasonable simplification to say that the carbonation hasn't changed at all. However, there is another property that is important, Solubility. When you open up the can, the drink itself will lose carbonation due to relatively low levels of CO2 compared to the container it was stored in as time goes on. When the drink is colder, CO2 are more soluble. So, as the temperature increases, there is less dissolved CO2, which likely causes the impression that the drink was less carbonated to begin with.

How do dressmakers/tailors make garments bigger or take them out?
|
Clothes are made from several pieces seamed together. Seams are usually created by folding the edges of the pieces over in a complicated way and sewed over. The way the pieces are folded on the edges depeond on what kind of seam you want to create . When taylor makes the clothes bigger he cuts the thread and undoes the seam. then he refolds it a bit differently. There is almost always a bit more cloth in the seam than is necessery so the taylor can fold the seam in such way that the clothes would be bigger. If there is not enough material the taylor can put a wedge of material in between the pieces. So at first there was cloth - seam - cloth, now there would be cloth - seam - added material - seam - cloth.

When, why and how did Monday through Friday become a classic work week, with weekends Saturday and Sunday?
|
Unions pushed for a standard 40 hour work week with 2 days off.Saturday is also a religious workless day. While most Christians celebrate the Sabbath on Sunday, Jews and some sects of Christianity celebrate it on Saturday. Until recently, there weren't weekends at all, in some careers , but when workers pushed for a 5-day week, it seemed natural to pick days that were traditionally rest days", 'In a lot of Asian countries, Saturday is not a holiday. Also, in the middle east, the work week is Sunday - ThursdayYou can largely thank Mr Ford for this._URL_0_

Other then the large influx of cash from the IPO (I get that reason), what are other reasons a company would want to go public?
|
I'll use Uber as an example and make up numbers. Two guys start a company. The company really catches on, but it is expensive to grow and they really aren't making much or any profit. The two guys own this company that they could sell for $1 billion, but they live on $100K/year salaries. $100K might seem like good money, but a person might want to live larger than that if they own a company worth $1 billion. If they do an IPO, they can sell 90% of the company for $900 million, that's $450 million each. Awesome, now they can live large because they have converted most of their ownership of the company to cash. Spending $20 million/year is a lot larger lifestyle than $100K/year. So, a year or two later the investors who own 90% of the company decide to get rid of the original guys. Oh, it sucks for them to be out of a job, but they still have their $450 million each AND their 10% of this growing company. Don't feel too bad about the guy who lost his job.

- Why do motorcycles only have manual transmission motors?
|
Motorcycles with automatic transmissions exist. Perhaps you don't see as many as you live in a society where people who ride motorcycles are the sort who want power and control, or are cost-conscious, both of which manual transmissions have an advantage. Also, there isn't anything about a standard motor which makes it 'manual' or 'automatic', the transmission is a separate piece which transmits motor power into the system which drives the wheels.Motorcycles are mostly enthusiast/recreational vehicles, so it makes more sense that most of the majority of them are going to be manual. Manual transmissions are also much more compact that CVT/Planetary ring gear automatics. Honda used to make a 400cc "hondamatic" motorcycle back in the 80's, but it sold like dog shit because motorcyclists are by and large enthusiasts and are riding for fun and excitement. People who ride for economical reasons and for simple transportation are better off with a scooter, which is twist and go.

Why scientists can date the age of Earth, but not the Egyptian pyramids or the Sphinx?
|
Radiometric dating works by comparing the ratio of isotopes in an object now to a known reference ratio at the object's inception. Each element has a different useful range of applicability based on the half-life of the decaying isotope, with increasing error and eventually uselessness outside that range. C14, for example, is only useful out to about 60,000 years. In the case of dating the Earth, it was actually the Uranium -- > Lead decay which was used to determine the age, based on the content of these isotopes in the oldest known zircon minerals in rocks found in Australia and Canada. As far as the Egyptian artifacts go, carbon dating only really works on objects which contain organic material. Dating the stone used in the construction of the pyramids and the Sphinx would of course tell you how old the rock is, but not when these objects were constructed.Carbon dating works by using a specific isotope which only accounts for about one trillionth of the carbon in a living organism, and is reduced by half every 6000 years or so. Dating the Earth works by using Uranium 238, which makes up over 2% of certain rocks and is reduced by half every 4.5 billion years .Scientists have different tools that can date different things at different ages. For instance carbon dating can date organic material that is up to a few tens of thousands of years old. But it doesn't work on older stuff and it doesn't work on things like stone. There are other dating techniques, but some of them only work on certain kinds of rock, or on things that are much much older. Different tools for different jobs. So it's not surprising when you hear that some particular young things can or can't be dated, or some other older thing can or can't be dated. It all depends on what tools happen to be available, and whether they apply to the materials that are available. Scientist love it when different techniques overlap, because then they can test the two against each other. That's how they get increasing confidence that their tools are working.

Is there any biological significance to "dating your mother"?
|
Not sure, but one could surmise there is an evolutionary aspect. "I know my mother was able to support and rear a child so a woman similar to her would have a higher likelihood of doing the same".

Whats that feeling when you're about to fall asleep that everyrhing feels small and heavy?
|
Could you be describing [Alice in Wonderland syndrome]? I used to get this pretty often when I was a kid. Not sure if this is what you're describing but a "fucked up" feeling when on the brink of falling asleep meets the criteria. The exact cause isn't known. Basically it's a disturbance in perceptions, such as perception of time, proprioception , sound , size, and distance. The state can apparently be triggered by migraines, lack of sleep, the Epstein-Barr virus , something else, or nothing identifiable. People have discussed similar experiences on here before, at length [ ] [ ].

Why do we sometimes remember dreams days or even weeks later?
|
That's probably a case of confabulation, where your brain makes plausible sounding lies to fill in a memory gap. The tricky part about confabulation is that you can only notice this when other people point out contradictory facts.

How did Lani Sarem and Handbook for Mortals "game" the NYT Bestseller list?
|
Usually the author or publisher buys the copies. The trick used to be that the NYTimes don't record every sale to create the best seller lists, rather they sampled certain bookstores and it wasn't too hard to figure out which ones were the sampled ones and then buy lots of copies of a certain book at just the sampled bookstores. Today, there are services that do a better job so a reasonable marketing budget is enough to buy enough books to make a best seller, especially in a less popular catagory. Think of it this way, if a publisher or author wanted to spend $100,000 on marketing, would they be better off spending all $100,000 on ads for a new book, or spend $50,000 buying the book and $50,000 on ads for the now NY Times best seller?

why is the Scottish independence referendum positioned as neck and neck in the polls, whereas the bookmakers odds suggest the opposite?
|
I expect that the odds are down to a significant number of people betting the outcome will be 'No'. Odds aren't just calculated by looking at what will *probably* happen, but also by the amount of money already taken in by people betting. If the odds were, say, both even , and a disproportionate number of people bet on 'no', then if 'no' is the outcome, the bookmaker will lose out significantly. By stacking these odds, they can encourage people to bet the other way.Sorry to ELI5 your ELI5, but just for those who have never stepped into a bookies If I bet £10 each on yes and no, do I understand right that a "no" result would get me £2.50, and a "yes" would get me £30? If so, that's a pretty sizable difference.

Is there a difference legal or otherwise between "sponsoring" a politician or bill vs a bribe?
|
Sponsoring legislation is the term for when a member of Congress introduces a bill, it has nothing to do with money, bribery or corruptionWell, these are kind of three different things. A campaign donation is simply donating any money to a candidate. Usually this would be done because one already supports the candidate . If that donation came with specific strings attached, or I offered something else as a "this for that" exchange, it 'd be bribery. The first is often alleged to be the second, usually on the logic of "this person got donations from people working in the oil industry, and voted to support the oil industry. Since the oil industry is bad, the only reason someone would support them is because they were \'bought and paid for\'." Sponsoring a piece of legislation has nothing to do with money. It is when a legislator supports a piece of legislation and wants their name and credibility attached to it, either to help it get passed or to take credit for it.Especially since the Supreme Court's decision that campaign contributions, even from corporations, were an expression of the right to free speech, very little. Individual campaign contributions are 'capped' under the Lawand over a certain amount, must be made public, so the size of your Institutionally recognized bribe is both public, and limited. Political contributions from organizations and registered lobbyists must also be made public, so the only penalty for our institutionalized form of bribery is political embarrassment, if anybody happens to be paying attention. About the only way you can be charged with bribery these days, is to make an agreement to sell influence or a vote in exchange for a a specified favor or amount of cash, and have it found out. Why would anybody bother? Where is Madame De Farge, now, when we REALLY need her?????

What exactly IS Citizen's United, and why is it bad?
|
Citizens United itself is a nonprofit organization that helps conservative candidates win elections. That's not important. What is important is that when Citizens United tried to broadcast an anti Hillary video before the Democratic primary, they were told they weren't allowed. This started the Supreme Court case Citizens United v. The Federal Election Commission. It ruled that *prohibiting* organizations from "broadcasting electioneering [which is working actively for a candidate or party] communications within 60 days of a general election or 30 days of a primary " is unconstitutional. Many people think that this gives those organizations more power and control in DC than the average person does[Citizens United] is a conservative political organization. They tend to fund advertisements favoring Republican candidates, and are mostly known for their involvement in a [landmark Supreme Court case] back in 2010. You'll have to judge it by context, but when people talk about "Citizens United" they usually mean the court decision. The case has to do with some intricacies of campaign finance reform, but the short version is that the court ruled it's unconstitutional to limit the campaign spending of private groups. Some people say this is a good thing because it protects freedom of speech. Other people say this is a bad thing because it reduces your "speech" to the amount of money you're able to spend. I think there is some truth to both perspectives. Either way, it was a controversial court decision that has profoundly impacted campaign spending.

How do all those many different anti-virus companies, even fairly obscure ones, have such huge but mostly similar databases of virus footprints? Do they get them from some common source?
|
Unfortunately I have never been able to remember the correct name, but there is an agreement to share virus information between "legitimate" anti malware companies. The exact definition of what defines a legitimate company, and how quickly to share the files has been debated a lot so I used to just refer to it as the quango whilst I was working for one of them. But also it is really easy to find new malware, just hang out on file sharing sites and look for the latest movie or tv show, or "cracked" software, and there is a good chance that the majority of the results you will find are actually just malware.Well yes, if by common source you mean the bestiary of malware present in the world. Why do all these different map making companies have such huge and mostly similar maps? because they're documenting the same world

Humble bundles.. and how it works from the game developers' perspective. Also.. how much does each dev get from a bundle?
|
Not sure about the first question, but the amount the developers get is determined by the buyers themselves. When you buy a bundle from the site you can choose how to split the money between all the developers, the charities and the humble bundle site.

Why does the Black Lives Matter movement not protest black on black violence in Chicago?
|
Because the purpose of the movement is to bring attention to the high ratio of black victims of police brutality. Black victims of police violence are often overlooked and their stories disappear. The movement is geared toward bringing this issue to light and helping to end it. Not every organization can work on every issue.They don't claim that they're trying to prevent the deaths of all black people from all causes everywhere, they are specifically trying to bring attention to the systematic racism in the criminal justice system. This is like asking why a cancer charity ignores every other disease out there.Black lives matter,?

Why are manholes located in the middle of the road?
|
It's best for city planning for them to run directly under the roads. After all, closer to the sidewalks, and you run into domestic gas lines, internet/phone cables, and maybe buried power lines. Sewers are very spacious, large pipes. It makes sense to put them under a wide, uninterrupted path with no other cables under it. Edit: this is all in the context that manholes are the access points to sewer lines.

Why didn't people see "the dress" in the original colors of the photograph?
|
The lighting had a lot to do with it. Our perception of colors are based not only on the actual color of the object itself, but also on the object's visual environment . The dress in question appeared back-lit in the photo, so instead of merely perceiving the actual colors a lot of us automatically color-corrected and subconsciously assumed that the colors were in deep shadow.

What happens with excess electricity from a generator?
|
If there really was excess electricity because the motor speed was too high, the voltage would rise. Voltage fluctuation is acceptable within certain limits, but past a certain point it could damage the devices attached to it. Generators you can buy have regulators to prevent this from happening - see [here] for an explanation with diagrams. Short version: a control circuit sends a DC voltage to a rotor coil, which actively slows the motor down as needed to maintain the correct voltageSmall experiment that you can try: -Find a bicycle dynamo or brushless rc motor .-Turn the shaft with your hand and pay attention to what it feels like to turn it around.-Now connect the wires, simply by holding them together. In case of the brushless motor, two out of three works as well.-Turn the shaft again, while still having the wires touch each other.-The current can now flow through the circuit, and this current generates its own magnetic field, resisting the rotation. Energy is never lost or created. Only converted into some other form of energy. Radiation, motion, chemical energy, etc.If you're talking about a single generator, the rate of fuel consumption varies with the amount of load. You'll burn through more gas if you've hooked it up to a larger load. It's not that there's excess electricity being generated - the generator only generates what's needed at that moment. How? Well, the generator is set to maintain a specific speed to maintain a constant output voltage. When you add a larger electrical load that draws more current, the generator will tend to slow down, and then the throttle governing fuel flow will open up to get the speed back up.
