Why are there no 'B' batteries?
|
there were. and A batteries AA and AAA came along later as devices shrunk, and before long, no one needed the middle of the road batteries anymore, you either wanted them small, or big. So A and B fell out of favor. They DO exist though [Here] is a picture of a B battery next to a AA for comparison

Why is the "eye" of the storm so calm. Why isnt it the worst part because its in the centre
|
It's like when water's going down a plughole. When it spins, there's no water in the middle. If you stood in that vortex, you wouldn't get wet or spun around. Or another way of looking at it - it's standing on something that is spinning. At the edges, you're moving much faster than if you just stand in the middle, because you've got to travel much further in the same amount of time. This doesn't quite hold in a hurricane, because other forces stop the outer winds moving as quickly .Because in the eye of the storm the wind is deflected and spiral upwards and around it instead of going right past it.

The science behind why I have the strong urge to yank the steering wheel, jump off high places and other stupid and dangerous things
|
This effect, called the High Place Phenomenon , is not entirely understood. A recent study has found that the urge may be the brain's way of forming an "escape plan" in the event that we need to flee. In this way, it actually reinforces our will to live. _URL_0_Those are a form intrusive thoughts. These are usually negative thoughts involving things like violence, destruction, sex etc. that just pop up occasionally. Your subconscious is always working in the background, including on things like "what's the worst possible thing I could do right now". Occasionally these thoughts just come to the forefront. It's perfectly normal and just a part of how your brain worksI always think of it as an extension of what has made our brains so fantastically powerful - we really enjoy altering out surroundings. You see that even in infants, they get a kick out of seeing a thing, and moving it, even if that means they just threw their favorite binky out the car window. That "Call of the void" feeling, to me, seems to be tied to that idea. Because the thought isn't really "I could jump off this cliff and then I 'd be dead." It's more, "I could jump of this cliff *and everything would change and no one can stop me*." It's a very primal reminder of how powerfully we can reshape the worldThere is a school of thought shared by psychologists called Cognitive Behavioral Therapy. It surmised that most of our thoughts are meaningless and have no intention. So thoughts of extreme violence that contrast your personality is just random thoughts with no meaning. There is a podcast called Invisibilia that did a piece on good people that carried dark thoughts and sought help.

how do big retail companies control/impose regulations on manufacturers and producers?
|
Big retailers can order 20,000 units of something, and all the other retailers combined might only make up 10,000 units. so when the big retailer says they want the product to be made 2cm shorter of last 10% longer or whatever. It is worth them setting up all the machines/procedures ect to make two thirds of there stock. but when one of the little retailers says they want something specific, for 10 units. It is far to expensive to re set up the machines and procedures for 10 units. So unless every little retailer got together and decided on what they all want, and negotiate as one, then maybe they would have some pull. but for the most part they can't. In the factory I work in, we make drinks, for big companies like schweppes or diageo. We will do whatever it takes, change the way we put on dates, sanitise the tanks in a special way, do the tests in the order and frequencies they like, make the syrup their way. However we also make drinks for individuals who want to make a new product or companies who make very small outputs. They don't get any of that. If we lost any on of them Its like 100 hours of production. If we lost schweppes its like 6 months of production. we really don't want to lose schweppes.

What came of the Occupy Wallstreet movement? Why did it end seemingly so fast and descrete?
|
Basically, because it had no coherent goals, and no ideological consistency. There were libertarians, anarchists, socialists, communists, all getting together to protest. Many of these disparate groups can hardly find a single issue to agree upon, other than to say, "The way things are now is fucked up." Without any tangible goals to accomplish, the movement basically withered away, as people realized that their continued participation was not having impact*Caution, this post contains opinion. This is my opinion, but I think 2 factors played into the demise of the movement. First, the occupy movement did not create enough "new" media cycles. In this day and age of 24 hour news, if you are not doing something new, the media will cover something else. Since the occupy movement were basically just sitting around , the media covered it for a while, but nothing new happened, and the occupations lasted for weeks and weeks. Well, some new things happened. Second reason: Negative things happened. People pooped on police cars, some people got raped, businesses near the camps started to suffer, someone died at one of the camps , etc. So, the media covered these events instead of the reasons for the occupation. As a result, public opinion turned on the movement, and people lost interest. One project that came out of it is [Rolling Jubilee], which is a charity that buys medical/student/home loan debt for pennies on the dollar and eliminates it by forgiving the people who owe it.

Why do I smell like garlic for a few days after eating it?

You actually do sweat garlic. Your body releases some of the chemicals in the garlic through your sweat.

What makes eggs so essential to a lot of baking recipes?
|
Eggs have lots of functionality in baking. One of the main functions in many recipes calling for eggs is to add structure to the product. Eggs contain lots of proteins wich will coagulate once they reach a certain temperature. Once the proteins "set" they hold their shape therefore adding structure to cakes or thickening custards for example. These same proteins are responsible for egg's ability to hold air bubbles when whipped. When you whip egg whites into a foam thousands of tiny air bubbles are trapped by the proteins. These bubbles make the finished product more light and airy. The most pure example of this is a meringue. Eggs also act as an emulsifier when mixed with two ingredients that have a hard time staying well mixed on their own. This adds to the overall texture and makes the product more stable. Eggs also have some other more minor functionsas well. Eggs yolks are a good source of fat which adds richness and creaminess to many products. Eggs contain a lot of water which contributes to keeping the baked good moist. Eggs also add flavor and important nutritional content to the foods they are in as well. Finally, eggs add color to baked goods, most noticeably when egg-wash is brushed on top of a product before baking, this will add sheen and allow for a darker finish. Hope this helps!', "Think about eggs like concrete. Eggs start out liquid, and then when you cook them they become solid. If you make bread without eggs, it crumbles really easy. Same with hamburgers. Often eggs are used to bind the stuff together so it doesn't fall apart while you're eating it.

What are the implications in "Miley, what's good?"
|
When you 've got an open conflict with somebody, being casual and friendly in addressing them is insulting & a show of dominance. It's like "u mad bro?"There's a social dialect issue at play here as well, which often gets overlooked. "What's good" is a phrase that in the area in which Nicki grew up is essentially used as a call-out. It can be used as a challenge to the other person or a public declaration that this person has done wrong and needs to answer, even if only verbally, for it. So when Nicki said it at the VMAs, she was essentially saying in a public forum, "Miley, I know what you said about me, I know what you meant by it, and everyone here knows it now, too. Explain yourself or shut up." That may not be the best gloss of it, but that's the basic gist.

Why websites like Facebook and Youtube update their interfaces less user friendly?
|
They are probably tested designs and are probably more streamlined, meaning that - you just think they're less user friendly because you're resistant to change. It's only human nature.
|
Do yellow jackets, hornets, or wasps have a purpose on our planet?
|
Nothing has a "purpose", like something bestowed upon them by some celestial third party. Their purpose is to live, and they do. Some wasps play a role in pollination of plants. Wasps are the only pollinators of many species of figs. Without wasps, those figs would be gone. Many insects and birds eat wasps, and honey buzzards and roadrunners depend on wasps for a significant portion of their diet.

Why are some NFL teams generally better than others over extended periods of time? Aren't new teams drafted every season?
|
New players are drafted not teams. The teams with the best draft strategy over several years normally end up being better. Many players that are drafted are not as good as hoped and others are better than expected. Basically it's a crap shoot. The best teams have good front office management , good coaches and good players.you vastly over estimate the turnover. The best players stay with their team on the order of 10 - 15 years. Great coaches also stay for a long time . While there is turnover on a roster from season to season, those are often fringe positions that simply do not matter much. The key talent is usually repeatedly there season after season. Brady, Rodgers, other top qbs, etc are not being replaced season to season. Thus, if you look at teams over these longer time periods, you do definitely see the ebb and flow of how good they are. Who knows, after brady and belichick are gone, the patriots dynasty probably does end.

Evolutionary-wise, why did humans develop a fully functional language, whereas animals didn't?

Short answer. Brain. Long answer. They're doing fine without one and evolution can't plan so it can't go, "Wow, language is working great in humans so let's develop that in cats."

Why is it impossible to film something in real life for virtual reality?
|
It would be possible, but you yould need a ton of 360° cameras and software that allows you to switch between each feed or even a super advanced program that stitched the feeds together, meaning you have a full 3D rendering of the room. To explain to your brother, you can only film something that you can see. If you are looking at a building and set up a 360° camera, it won't be able to show you the side or back of the building, you would need extra cameras.

Why do thrash/speed metal bands tend to slow down their sound after a few albums?
|
Most Bands change their style as time goes on. When u start out playing fast I think the natural progression would be to slow down a bit.I think as you age, you lose your youthful aggression and things just become mellower. Every band that I love from the 70s prog era makes horrible music now, they're old and serene and philosophical and no longer emotional and aggressive and the music suffers.When the bands got bigger they played bigger arenas rather than clubs. Without a very good PA all that technique and speed in the thrash gets lost in reverberation and echoes. For a big arena more chunky riffing sounds better.Playing thrash is very limiting, there's not much you can do with it. After years of playing it it's normal you are gonna be wanting to do something different.It could very well be that these bands start out as young people who need music a certain way but then they eventually "grow up" a bit so their style changesDid not know that Slayer have slowed down over the last decades

Why do the currency exchange rates change everyday?
|
Everyday? Try every nanosecond. Just like other items in the market you can trade, such as stock or bonds, currency operates in a very similar manner, there are a trillion and one factors that go into how much a currency is worth compared to others, and these factors are changing non-stop.

in America, why is traveling by train more expensive than traveling by air or bus?
|
From an energy perspective if all three modes of transportation were going from the same point A to point B via the same route the train should be cheaper as it's more energy efficient. One huge perk that planes have is that they can fly in a straight line to their destination where the trains can only follow their tracks. A straight line is always the shortest. The track is a bit of a burden. You need a very long and narrow plot of land to lay your track on. If you don't have this you need to rent someone else's which increases cost. It's also a lot of infrastructure to maintain and your workers need to travel a lot unlike a city street worker. After all of that any given foot of rail is traveled less frequently than a foot of road. The number of riders affects this a lot too. Low ridership reduces the efficiencies of scale and drives up prices. As prices go up less people ride. So it's self perpetuating. In certain local or frequently traveled routes its pretty competitive. I live in the twin cities and we're expanding light rail like crazy. If it would pick me up by my house and drop me off at work I would definitely commit to using it daily as it would be cheaper than driving my car.

How does your body know that you want to just fart and not just crap in your pants?
|
Your bowels can feel gas versus a solid log. But sometimes when poo decides to enter the third in between state of matter known as liquid, your ass gets confused. Hence the term 'sharting, . This is the result of your colon and spincter sensors think there is a gas build up . However since liquid behaves like a gas the ass gets confused. That is when the spincter decides to let loose on what is *thought* to be a gaseous fart. Suprise suprise, looks like your in need of some new shorts. Or you have to throw your underwear away and go commando for the rest of thr day . Short answer you have nerve endings all throughout your colon and sphincter that help aid in this delicate decision making process. An accumulation of muscle memory over time leads to the appropriate response .

are all people with the same last name related? Why are some last names so common?
|
Because last names are a more recent development. Back in the day, people were largely known as , son of _. In a small village, that was enough to identify who's who. But then, when populations grew, you needed a better way to identify people, especially through generations. So instead of being John, son of Michael, they started using their job, or some other descriptor. "I'm John the Smith." "I'm Peter the Farmer." In other areas, like Scotland and Ireland, the "son of William" thing became multi-generational. Peter McWilliams passed along the McWilliams to his son, despite being the son of Peter. In an indirect way, we are, of course, all related, but not all Smiths are more closely related than a random Smith and Brown.

Why does water taste so cold when I'm chewing mint gum?
|
Minty products contain menthol which causes the same "hey it's cold in here!"\x9d signal to be sent to the brain, even though menthol doesn't actually cause the temperature in the mouth to change. Water just causes this to happen due to the mint in the gum.

Why does a steamy shower help clear your nose when you are sick?
|
The increased humidity and heat allows the mucus to loosen and flow similar to warming up a thick sauce for a stir fry. You increase the molecular speed and as a result it flows out.

Why is it that their is a clear accent among the black population in the United States but there isn't one in other countries that have black populations such as Britain?
|
African Americans sometimes speak a dialect known academically as [African American Vernacular English]. This is what you're referring to, and in fact there is a british equivalent: [Multicultural London English]. The reason you as an American can't tell the difference is simply because you aren't constantly immersed in British culture and so your ears aren't trained to hear the difference.They do. Listen to this interview with London rapper Dizzee Rascal. He clearly has an accent that very few white people from London would have. _URL_2_', "The majority of black people in the U.S. are descended from slave populations dating back to the 1700's. From that time, until the mid-1900's, they were extremely segregated from White America. When two populations don't interact much, their accents will naturally drift apart.

What is net neutrality? And why it is good or bad.
|
Net neutrality was the concept that said that every website, regardless of the content or bandwidth requirements would allow the same amount of bandwidth and speed for every other site. It's good because it's a "free internet". In a system without it, ISPs can artificially limit the speed to said websites, or charge more for their access_URL_0_ Netflix users that had Comcast were experiencing lag/buffering problems recently. All of that is seemingly disappearing after their deal. Comcast will never say they were throttling Netflix, but circumstantial evidence seems to point at they did. Net neutrality is important, and this is just one example.

How can my prescription cost $400 at my local pharmacy, yet the same prescription cost $0 from a mail order pharmacy located in a different state?
|
It's how your plan is structured. Even if the cash price of the drug were the same your plan will pay less of that cost for going to your neighborhood pharmacy. Many insurance companies own their own mail order, basically paying themselves to dispense to you. TL;DR: the insurance coverage changes, not the actual cost of meds", 'Usually the way insurance works is that insurance will cover a certain portion of the medication and you pay the remaining cost yourself. The portion you pay for yourself is called the co-pay. Depending on your plan, you will either have a set co-pay or a percentage . If you don't pay a copay for prescriptions, that means your insurance company is paying 100% of the cost. Your plan should outline what your co-pays will be but no one ever reads the details of their plan and most Americans don't even know how their insurance works at all. In your particular case, I'm going to guess that your insurance company also owns the mail order pharmacy. Some insurance companies "force" patients to get their prescriptions at the mail order pharmacy that they own by making the co-pay $0 when filled at the mail order pharmacy but making the patient pay for all or most of the cost when filled at outside pharmacies. Source: PharmacistHow do you go about finding out that you can get it elsewhere for cheaper? My husband is on meds that cost us almost $500 a month, so $0 would be super nice.It's kind of the opposite for me. I can go to my local pharmacy and pick up prescriptions, but if it's a long term prescription insurance will only pay for 3 pickups and then I have to pay full price. They want you to use the mail order prescriptions. I was put on a prescription and I could go to my local pharmacy and get it for $10 a month. So now I have to order it through the mail and I get a 3 month prescription for $86. So I'm kinda getting screwed.

Why does string theory matter?
|
Physics, right now, is divided into two sections: general relativity and the standard model. To simplify it drastically, general relativity basically discusses the physics of really big things and the standard model describes really small things. The problem is, general relativity takes gravity into consideration and the standard model, because of the kind of maths involved, cannot. What this means is that it's hard to mathematically join the two models, which is a problem because most physicists think we can't have two different models to describe one thing . If string theory is proven to be correct , it basically unites the two previous models by providing an alternate way of describing them. It uses lovely things like the existence of 11 dimensions and miniscule strings that vibrate and interact with each other to create matter and energy, and therefore can describe everything. So why does string theory matter? It matters because it's a way of understanding the universe without having to resort to two different ways of analyzing it, and to many people, it's our best chance of doing so.

Why does it feel like you can't breathe when you get a gust of wind in the face?
|
When a fluid moves rapidly, its pressure decreases, thus sucking things into it. You may have observed this when your shower curtain clings to the stream of water from your shower. Similar effect happens here and makes it harder to breathe in air.According to [Bernoulli's principle], the faster a fluid is moving, the lower it's pressure. Air can be considered a fluid when you're talking about physics. This means that with a gust of wind, that air has lower pressure than normal, and since we rely on a difference in pressure to breathe in , it makes it harder to breathe when there is a lower air pressure around us, as would be caused by a strong gust of wind.

Why is it that after you say or type a word many times in a row, you'll begin to question yourself as to whether it's correct
|
It's called [Semantic satiation]. Quoting wikipedia: > The explanation for the phenomenon was that verbal repetition repeatedly aroused a specific neural pattern in the cortex which corresponds to the meaning of the word. Rapid repetition causes both the peripheral sensorimotor activity and the central neural activation to fire repeatedly, which is known to cause reactive inhibition, hence a reduction in the intensity of the activity with each repetition.Can we put the Wikipedia link to semantic satiation in the sidebar?', "This happens to be called *jamais vu.* It's related to *deja vu* and *presque vu* . Not an explanation, but I think it's interesting nonetheless.

Why do people use AskReddit and eli5 subreddits when Google can usually answer their question?
|
I don't know, maybe you should Google that.AskReddit generally has more community input. Questions like "Cashiers of Reddit, what products do you silently judge people for buying?" or "If your SO lost their memory, what would you not tell them about yourself?" don't have a single answer, it's about a community discussion. Granted some questions *could* be googled, but some people just don't. With ELI5, often times askers just want a simple, paragraph long explanation. Sure there might be something on wikipedia, but maybe it's too complex. Or the answer on Yahoo answers isn't good enough. ELI5 gives you a chance at a simple answer as well as an easy ability to follow up if it doesn't explain everything. Again, like certain askreddit questions, google is sometimes a better option, but many times it doesn't give what the asker wants.Because it's more fun to interact with people on the internet that to just do a simple Google search.

Why are sellers allowed to post items at an insane markup to appear that they are on "sale" on Amazons deals of the day, or sales events?
|
There is no real regulation, outside of price gouging, utilities, or fixing, that mandates the price a seller can provide. Price gouging refers to taking advantage of people in need during an emergency , and then there is also public utilities where the government ensures citizens get a fair price for things they need to live their lives, like water or electricity. Other than that, the free market is assumed to take care of any other problems. A seller marks up his item under the risk that no one will buy it if a competitor kept his price low. The last issue mentioned, price fixing, is when sellers get together and agree to all mark up an item simultaneously, which is mostly not allowed without justification beyond greed. However, those three items aside, the answer to your question: "Why are sellers allowed to post items at an insane markup?" is simply, "Because it's their property and they can sell it for whatever they think you'll pay for it." The only thing stopping them is you, and your ability to refuse to pay that price while shopping for a more competitive offer.

Why are contests in Canada always open to "legal residents of Canada (excluding Quebec)"?
|
Quebec has a bunch of policies about sweepstakes that the rest of Canada does not. Rather than spending a bunch of money to make sure all the rules are followed, companies prefer to just not run the contest in QuebecThey are a rogue state. Source: I am from Vancouver.No research. Might be wrong. Contests are heavily regulated in Québec. All information must be avalaible No purchase must be necessary. We also have to answer a mathematical answer in a lot of cases. So yeah I am all over the place with this answer but it boils down to laws. It's just easier to exclude Québec. Ha ha. Separation joke.In Québec, as others said, contests are heavily regulated. Everything must be verified by certified people to protect contestants from fraud. Also, the prizes are tax exempt. If the prize is $100,000 the winner gets all of it. This means that the organization must pay the taxes themselves to the Government. So this may very well having a contest available to Quebec residents be cost prohibitive to the company that essentially uses the contest as a form of advertising.Because according to provincial law, anything pertaining to the contest must be available in French. Most companies cannot be bothered with translating everything, so they'll just explicitly exclude Quebec from their contest.

Why is there 360 degrees in a circle, not something like 500?
|
There are 360 degrees in a circle because the Assyrians were the first ones to do geometry and write it down. The used the base-6 system. They are also responsible for 24 hours in a day, 60 seconds in a min., and 60 minutes in an hour. And supposedly the only word we get in English from that long ago people is the word abyss, which still has its original meaning.There isn't. There's 2 pi Radians. There can be whatever you want there to be. But look at 360. Before calculators people did stuff by hand. 360 divides evenly into 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, and a bunch more . too drunk to math. 500 or 100 actually has relatively few divisors. So it's just to make the math easier. You can divide it into whatever you like and the math still works, so long as you define it clearly.From Wikipedia: A theory is that the Babylonians in ancient times subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree.Babylonians counted in sixties. That may come from counting to twelve on one hand using the three parts of each finger, and then five twelves makes sixty. To write numbers they had symbols for one and ten and grouped them to get up to fifty-nine, then put a 1-symbol in the next column for sixty, like how we write ten as 10. 360 degrees - six sixties - for a full circle makes one sixty the angle of an equilateral triangle . It's also nearly the same as the number of days in the year.

the POW-MIA dilemma from the Vietnam War era?
|
It was basically an issue of trust. At the end of the war, about 600 POWs were returned to the US. But there were about 2,500 men unaccounted for, most presumed dead, but without proof. Because of bad relations with Vietnam and surrounding countries, the US could not easily investigate whether any of these men were still alive. The war was very unpopular, and the was little political motivation to draw things out. The US government said there was no evidence any prisoners were left behind, and wanted to move on. The problem was, trust in government was at an all time low. Grieving families clung to the hope their loved ones might still be alive, often in the face of facts, and did not believe the government when told otherwise. This grew into a cause célèbre, with several high profile action movies in the '80s dealing with the rescue of Vietnam POWs. Relations inproved in the late 80's and 90's and eventually the US was allowed to launch full scale investigations, eventually confirming about 500 as dead. Unfortunately, distrust and emotion runs deep, and unless the bodies of every last man were recovered, there is no way to absolutely *prove* they are not alive. In the end, none of the unaccounted men were ever shown to have been alive.

If I buy something from a store that's supposed to support a cause, how does it work? Are poor children actually getting a pair of shoes if I buy a pair myself?

Ask the store. It could be anything from "1% of the profits we make to "We buy from independent makers from poorer countries, and then sell on to you". The range is massive.

How is it possible to sleep for a few minutes, yet dream for what feels like hours?
|
Odd, for me, I sleep for hours, and it's lucky if I remember more than a couple of minutes of dreaming.The apparent passage of time from one's perspective is very subjective and dynamic. Time flows faster when we're happy, and slower when we are bored. If our brain is capable of creating the entire dream world, it's easy to imagine it's also possible for it to recreate the same feelings and emotions we experience in our reality, such as the feeling of being in one place for a long time. Think about it, there's never a "start" to a dream, you are simply thrown into the setting, and you kinda already know what's going on. You might "start" a dream with the feeling that you 've already been there for 2 daysYou often backfill you dreams with false memories that can make them seem longer. Your dream might start with you driving your car three states away. To make sense of this, your brain creates a scenario where you have been driving for hours, complete with memories of some of the things you did in that time. Or, like a TV show, your dreams often skip over the boring parts. Your grandfather says "we are going camping", and suddenly you are at a campground, no packing, no driving although your brain might create memories of those things if necessary.

What would happen if the Earth's rotation changed. For example the sun rises in the north and sets in the south.
|
The Arctic and Antarctic circles would expand to the equator. Summer and winter would be the same as day and night. The polar icecaps would be constantly shifting.
|
If we could drill through the earth...and then jump in it...what would happen?
|
_URL_0_ This pretty much explains what you're asking.I have read about this a while back. Basically you would jump straight through and speed up all the way , and once you reach halfway you would gradually slow down again until you reach the other part of the hole. From there on you would have slowed down enough to land on your feet as if nothing happened. But of course the heat and gravity would tear you apart when inside the earth.

Why does pop-corn pop?
|
Popcorn is a specific variety of corn - most corn will not pop. What causes it to pop when heated is that there's a drop or two of water inside. It turns into steam and cracks the shell to escape.Popcorn pops because water inside the kernel is heated to the point where it turns into steam. The steam occupies more volume than the inside of the kernel at room pressure, so it applies force to the kernel shell to try and get out. Make it hot enough and the pressure is high enough and the shell fails. The steam expands the inside of the kernel, like whipped cream, and the heat hardens it into a new "popped" shape. Popcorn is a special breed of corn with extra tough shells, to make this process work.

If I have 20 mb/s download speed, why do files generally download at only a fraction of that speed?
|
Make sure you are not confusing MB/s with Mb/s . Most speed tests and Internet Service Providers measure bandwidth in Mb/s , however some file downloads are measured in MB/s depending on what software you use. There are 8 Megabits in 1 MegaByte, so 20 Mb/s would be only around 2.5 MB/s.Your '20mb/s' isnt megabytes, its megabits. If you do a conversion you would see that 20mb/s is 2.5 mb.There are other factors besides the popular "1 MB is 8 Mb . Bandwidth and server traffic of your download source can also play a part in your download speeds. If youre using a p2p network such as a torrent, your speeds are high influenced by your connection to peers, and their upload speeds and what % of a file they already have. Addtionally Data is sent across the internet in "packets", so the video youre downloading is being sent to you in about 5,000 pieces. Each one of these pieces has information in it to help your PC identify it/make sure its valid and not corrupted. This additional info adds space to the packets, thus making your download larger than it appears, thus making it take longer as well like others have said, the MB/Mb is the biggest factor', "As others have said, the key thing to look out for, is it is capital MB/S or small Mb/S. Bigger numbers look better, so ISPs demonstrate how fast their net is using the biggest metric they can. MB/S is a lot more useful to the average user, but is a smaller number. The larger number is useful to know for a lot of things other than downloading though. Take the number from speedtest and divide it by 8, that's your DL / UL speed. You might sometimes get a bit more than your advertised speed, I know I should download at a set rate, and sometimes my ISP is nice enough to give me 5% more than I should have as max during quiet times.

Whenever I get drunk and I crave human interaction?
|
Congratulations! You are a friendly drunk. You also likely an affectionate drunk so take care with that. Like others have said, alcohol lowers your inhibitions and generally dissolves whatever filter people have between brain and mouth. Since your other choices are "Angry/bitter drunk" and "Sad/whiny drunk" you came out of this ok. Now someone needs to invent a breathalyzer for our phones before the calling and texting gets overly friendlyAlcohol generally lowers your inhibitions, including the inhibition against socializing. It's why they call alcohol the "social lubricant."Your inhibitions are lowered, allowing you to "get outside your skin" for a bit and enjoy the natural state of being with other humans. Humans are biologically programmed to crave attention and affection from other humans. This is why out of all the millions of things we could be doing, we almost always want to be with other people doing social activities . Alcohol also makes you look [more attractive], allowing you to get receive more attention from others . Alcohol also makes others look more attractive, and combined with the lowered inhibitions, allows you to be less neurotic and more inclined to talk to them.

Was scurvy actually particular to sailors? It seems like citrus wouldn't have been available to most of the lower classes
|
Scurvy is caused by a lack of vitamin C. Vitamin C can be found in peppers, turnip greens, cabbage, broccoli, tomatoes, peas, and other foods. A lot of those would be available to the lower classes at least some of the time.Citrus isn't the only source of vitamin C, it just happened to be a good one for ship-goers since most things that were cheap and vitamin C rich were perishable.

when one eye gets irritated, why is the body's reaction to blink both eyes instead of winking the irritated one? Is there a reason winking is a manual function?
|
Without going TOO deep it’s just an innate, automatic, “consensual reflex” to protect your eyes. When one eye blinks the other should too. When someone has an eye injury we usually patch it/cover it to protect it, that way your body’s automatic response to “flip out” and over-blink to remove the threat to its partner is suppressed so that the injured eye isn’t being further irritated bye the over-compensation. That’s why winking takes effort, it’s an voluntary choice you commit to either eye. Hope I explained that decentlyYou're asking a "why doesn't" biology question, so it's hard to give a definitive answer, but Blinking probably evolved very early in vertebrate eyes--perhaps simultaneously with eyelids. Autonomic responses are very deeply wired, and there has probably never been any selective pressure for automatic winking. Blinking works well enough to protect mammalian eyes, and costs virtually nothing.

Internet network speed: What's the difference between "kbps" and "KB/s" transfer rate?
|
Little b, big B. Big difference. Little b = bit. Big B = byte. 8 bits in a byte. 10370 / 8 = 1296.25Capital letters are important here. "mb/s" should never be used, because it's ambiguous. KB, MB, GB, means kilobyte, megabyte, gigabyte, respectively. Kb, Mb, Gb, means kilobit, megabit, gigabit. "kbps" or "mbps" is another way to write Kb/s and Mb/s. The final piece of information needed here is there are 8 bits in a byte. So putting this all together, 10370 kbps should be exactly 8 times the 1296.3 KB/sec given in parentheses, and if you get out a calculator, you'll find that it is.

How can a decrease in the global price per barrel of oil create a negative affect on local, national or global economies?
|
Plenty of industrialized/first-world nations produce oil, so lowered oil prices means less profits for those industriesIf the return on money spent getting oil dips too low, thousands of people loose their jobs. As an aside, those people make ALOT of money doing it, and are generally giant assholes. So they have a hard time doing anything else, especially if it has them dealing with the general public.

How does basic universal income work?
|
The basic idea is to give everyone a set income that they would first spend on housing/food/basic amenities, guaranteeing them their livelihood. They would be able to spend their time how they chose without being bogged down with a 40 hr/week job . People would still be free to pursue work if they chose but it would not be a struggle for survival to find a job, instead it would be a means of improving your situation. while a majority of people may be content to just live on the basic income, there will be a portion of people that want to follow their dreams and in doing so improve things for everyone. You'd be amazed what people can accomplish if they don't have to work 40 hours just to survive and could instead spend that time making a difference.I hate to just link to other posts, but this has been discussed a lot.

We dont "send" them like we send troops. We ask how much to go to Isis territories and fight the locals. They give a price on a man per month basis. We say Ok. They pack up and goCan they - yes. Could the US afford to pay them to do it - also yes Are they willing to do it - probably not Will they make a total hash of it - probably yes

How Did Baby Boomers ruin the economy and housing market?
|
Well blaming it on ONLY them isn't necessarily true. Long story short: someone approved giving big loans to people buying houses. More people bought houses and kept making money by selling their previous home and buying more houses. As long as the market kept increasing in value through inflation thanks to the increased interest in buying homes, they keep making money to pay back banks and a little extra on top. Eventually there was too much selling, and just like stocks, the value dropped due a saturated market. People panicked and wanted to sell, causing value to drop even faster. My family isn't comprised of baby boomers. My family did this, and we lost quite a lot.

When an episode of a series require several flashback scenes e.g. all scenes where people get slapped, do editors go back and scan all the previous episodes or do they keep some list beforehand?
|
To create a montage of clips where character A gets slapped, an organized editor could reference episode summaries or other tools to quickly locate those scenes. A disorganized editor might rely on memory and miss/forget a few. A truly awful editor might need to re-watch great swaths of the show to find the scenesThe easiest way would be to pull up the text files for the scripts and search them for "slap", then pull the footage for those episodes from storage and cut them into the new episode. With this method you might miss any slaps that were improvised, rather than scripted, but there shouldn't be so many of those events, and there's the possibility that something like that would stand out in the memory of the cast and crew. How scripts/footage are stored depends on the production company and isn't something I can say too much on. I 'd expect that any scripted show would keep old scripts somewhere accessible, though. Footage might be trickier. Raw HD footage gets really, really, really big, and if you're keeping everything raw you 'd probably need to invest in some extra storage media regularly to add to your archive.

Is a fat muffin top at your belly caused because humans wear clothes around their waistline?
|
Yes, but not by much. Your fat stores are all located in/around your hips/pelvic region, they swell and become distended due to an increase in volume of fat storage. Squeezing into tighter clothing does cause certain shapes to form, but it has no impact on the overall volume. So if you are carrying weight in your belly it's not like that weight is going to suddenly shift to your thights, it'll still be there but just in a different shape.Really good question! I am by no means an expert but it is my understanding that every person stores fat on their bod differently, however fat naturally collects around the waistline, modern clothes or not. Wearing tight jeans or yoga pants accentuates the “over hang” or “muffin top” on some people.

How can an igloo stay warm without melting?
|
It does melt a little bit. Heat is trapped on the inside, but on the outside, it is still very cold and kept frozen. All the ice the igloo is made of is in contact with more ice on 4 sides, and 1 side is facing outside in contact with very cold temps and wind. The blocks are also quite thick so the ice is better insulated. The result is that the warm air on the inside of the igloo is only in contact with 1/6 of the surface area of the ice making up the igloo, so the structure is still kept very cold, while trapping warm air, protecting against wind, and insulating. Since the ice is thick, that 1/6 of the surface area doesn't effectively warm the bulk of the ice, so it stays frozen.Compared to arctic temperatures at night, 0°C is actually quite warm. And although ice is not a particularly good insulator, similar to rock, snow has very good insulating properties due to the pockets of air within. Therefore, it takes very little energy to keep an igloo at 0°C on the inside.

Why do you instinctively gasp when falling?
|
I was told by a martial artist that it is the same reason they scream when they throw a punch or kick. It tightens up your core and gives you "extra strength". Why your body would do this instinctually is, when you hit the ground you are not a flimsy noodle that gets squashed. Not sure how true, just what I was toldbasic fight or flight response. Your sympathetic nervous system increases your blood flow and breathing rate when you are in danger. So when are startled your heart pounds and you gasp for air.

How do companies like Facebook and Dropbox get their profit?
|
Facebook has tons of ads and makes a billion dollars quarterly through advertising and promotion.> Facebook doesn't show ads or requires me to pay anything. Facebook shows ads. Also it allows post promotion, which means that you pay for your posts to be more probably shown in users feed. > Dropbox gives me lots of free space to begin with Yeah, but that's only few GBs and many times it's not enough, you can expand it by paying.

How is it possible for some childeren at a young age to enter college?
|
You don't necessarily have to finish all the grades to enter college. You can also take an entrance exam which determines if you have enough background knowledge, and then sometimes exams to skip prerequisites for courses. Lots of kids are accepted to community college before they graduate high school - my son took calculus at community college when he was a freshman in high school. He just had to test *into* the college and then *out of* precal.It is possible to skip regular school by: Testing out of classes, Taking the GED instead of normal classes, being home schooled and taking their exit exams that qualify you as having passed high school material. There are also possibly other options depending on the school district and State your school is is. Additionally many Colleges/Universities will let anyone that passes their entrance exams take courses regardless of what age they areyou have to pass the tests, not necessarily go thru the classes. you can take accelerated classes and do summer sessions to get ahead. i went to school with a kid that was taking college math class as a 8th grader.

Why do I feel like I need a shit after drinking coffee?
|
Some studies say coffee causes contractions in colon muscles. Apparently haven't been too many studies but I would say it's also combined with the natural time for most people to go #2. We could do our own study, next time trade your coffee for caffeinated tea or a Coke and see what happens :) we can at least see if it is a coffee-specific issue. _URL_0_

If space telescopes are so powerful that they can see light years away,why can we still not see the surface of closer planets?
|
My eyes are so powerful that I can see a couple mountains from my office in Lexington Kentucky several miles away. However, I cannot read a sign on a shop window less than a block away. One must keep in mind scale_URL_0_ XKCD to the rescue. The core point is that planets are small, moving really fast and are spinning. Its a challenge for telescopes to resolve anything. That even ignores atmospheric interference which is a non-trival issue as well. So looking at something really really far away is actually easier than looking at a close planet because its moving slower in a relative sense_URL_1_ We do have images of planet surfaces in our solar system, but remember that Jupiter, Saturn, Uranus, and Neptune are gas planets. They don't really have a "surface" or if they do it's the surface of their atmospheres which we have clear pictures ofBecause planets, compared to stars, are really, really small. That being said, we *can* look at planets with them. [Here] is our best map of Pluto from Hubble.

When I pour water into a glass of ice, why does the ice make a crackling sound for a few seconds?
|
Well as you may know, water expands when it freezes. When you pour warmer water it warms the outside of the ice causing a temperature difference between the inside and the outside temperatures. While the outside of the ice is being warmed it contracts while the inside of the ice doesnt change much. This causes great stress inside of the ice cube and starts to crack the ice apartThings expand and shrink if the temperature changes. Ice is not different: It starts out quite cold and gets a little bit warmer on the outside, whereas the middle stays cool. This means that the outer layers of the cube shrink a little bit more than the inside, this causes stress in the ice . The sound you hear is the ice breaking and moving a tiny amount.

Why it is perfectly acceptable to have people wearing only underwear in picture advertisements but we ourselves are not allowed to stroll around in just underwear.
|
Why do you think we're not allowed? A bathing suit has the same amount of coverage. As long as it is opaque it should be fine, though some cities enact ordinances otherwise. As far as private property, like a mall, they are free to set their own standards. They can kick you out for not wearing shoes even though it's perfectly legal to do so.

Is human knowledge just a tower of assumptions, each block reliant on another, that would collapse if a fundamental "truth" at the base was proven false?
|
Sure, if our Axioms were proven false the entire system built on that Axiom would collapse or at least take a heavy hit. Thing is that our axioms are pretty sturdy and are often self-defining. A triangle has angles adding up to 180 degrees. You cannot disprove that because any shape that has a different sum of angles is not a triangle> Throughout history, every "truth" seems to be discredited or falsified sooner or later. Only very few of them actually. You're ignoring the billions of facts that have held trueIt happens all the time. That is baked into the scientific method. Our knowledge is not based on taking axioms as immutable. It is based on asking questions that lead to more questions. When a huge assumption is proven to be false, it usually leads to a radical advance of scientific understanding and technology.

Why is it so hard throwing an object straight upwards when lying down?
|
When you were a child you took a long time to learn how to throw properly, moving your body in just the right way. Throwing is actually quite a complex action, using lots of muscle groups, and if you try to throw in a particular way without having practiced a lot, for example with your non dominant hand, or lying down, you will tend to just use your arm which gives you far less power and just feels wrong.There's a bunch of factors at play here. - First, your elbow has a severely diminished 'windup'. As the elbow cannot move below the floor, you have a 'shorter runway' to throw something. - Secondly, a surprising amount of force generated in a throw comes from your entire body movement. Your shoulders and hips *both* rotate to add in force, speed and also alter angles for better leverage. - Third thing ties in to the second - Your legs and feet provide a base against which to push off, one that isn't available when you're lying down.

How do microwaves work? And why is that an empty container next to a container full of food will stay cool and the food gets selectively heated?
|
Microwaves use radio waves to excite the water molecules inside an item to heat it. Since the empty container has little to no water in it, there's nothing to excite and cause heat

How does our body develop immunity against diseases such as smallpox after we recover from it.
|
> whats the mechanism for it? [Some basics on the immune system] Your body is constantly producing B cells covered in antibodies, which are Y-shaped proteins. On the arms of the Y shape, there are different shapes. They will react to foreign molecules, such as those on the outside of a smallpox virus . When a B cell with antibodies encounter something the antibodies recognize, your immune system starts to make tons more of those antibodies, and produce long-lived cells that make that antibody. Antibodies stick to the thing they react with, so that your immune system can destroy them better. Once the infection subsides, those long-lived cells keep producing the same antibody, so if the same germ gets back inside you, your body is already prepared. > why do we not develop immunities against common ailments such as the flu? We do! Every time you get a cold or flu, it's a different cold or flu virus. Some germs have molecules on the outside that change very easily, and others don't. This is why you can gain long-term immunity to some diseases and not others.

How are stock prices calculated?
|
A typical stock's price will change numerous times throughout the day, based on its last known sale price. Stocks are quoted in two different numbers, the "bid" , and the "ask" . When a transaction actually occurs, the exchange computer registers it, and that becomes the latest quoted stock price on your Yahoo or your Google finance. The "closing price" at the end of the day is just the value of the last completed transaction, and the average price is just simply the average price that it commanded during the day. There's no secret formula or anything - it just follows the last known sale and updates to that figure throughout the daythe price listed on a stock exchange is NOT a calculated price. it is merely the price that the stock was last sold/bought at. the stock exchange is the computer system that keeps track of these sales.
|
What exchange rates mean?
|
It doesn't really matter if one is higher or lower. What matters is the change in exchange rate over time. So if country A to country B exchange rate was 2:1 last year, and today it is 1:2, then that matters because it affects prices of goods that are traded between those two countries. But if they stay relatively stable relative to each other, then it doesn't matter.

What's going on in your head when you have a "deja vu" moment
|
During Deja Vu short term/current experiences are being written in real time to the area of the brain used for long term storage, and then immediately recalled concurrently. Memories are not usually written here during times of consciousness, so your brain interprets it as reliving an experience. It is basically experiencing a current event as a memory and event at the same time.

Why does giving babies peanuts earlier on decrease the risk of them developping peanut allergy?
|
Parent of a peanut allergic kid here. Unfortunately science doesn't know yet the exact mechanisms that lead someone to develop a peanut allergy, except that certain genetic factors predispose one to allergies, asthma, and eczema For many years the medical wisdom was that early exposure before the immune system matured could cause children to develop food allergies . So by delaying introducing common allergens until 2-3 years old, you 'd supposedly avoid allergies caused by doing this too early and instead waited until your immune system was trained and "smarter" to recognize a real hazard from an everyday food. Eventually scientists noticed that this isn't true globally. For instance, in Israel few people consume peanut butter but everyone eats a peanut snack called Bamba from a very early age, yet peanut allergies are less common than in the US even among American jews who are genetically similar. After doing a series of studies where some babies had early introduction and other babies had the late introduction, it turned out that those with the early introduction were less likely to eventually develop an allergy. This was statistically significant, which means that some babies still had a bad early reaction, and this was more likely if you had high risk factors like family history. I don't believe there is yet a proof of the cause of this preventive measure and whether it acts like a vaccine, but the difference was significant enough that the recommendations were effectively reversed.

Why does an image formed by pixels on a screen remain sharp, when light tends to spread out over distance?
|
The image from the screen *does* become wider as you get away from it, the same way it does from a torch That's why if you and I sit a few metres apart, we can both see the same screen. However, unlike the torch, each pixel is generating light in a very tiny place. From that place, light is emitted in all directions - but only one of those directions lines up with your eye, which is why it remains sharp when it reaches your eye.You could ask the same question about everything you can see: we see something by virtue of light being reflected off it, and that light spreads out as well -- so how can we see it in such sharp detail? The answer is because our eyes contain lenses. Light that reaches the eye is indeed spreading out, but the lens changes the direction of the light and reverses the "spreading out" so that they focus on the retina and generate a sharp image. As you get older, you may find the lenses in your eyes don't work so well, and your vision becomes blurry. This can be corrected either by surgery -- using lasers to slightly reshape the lens -- or by putting artificial lenses in front of the eye .If you held a piece of translucent paper over the screen you would see an image. Move it away just a few mm and it becomes blurry. Move it farther away an there will be no image, just an average of the colors on the screen. That is the light spreading out from the screen. Now stick a magnifying glass between the screen and the paper. At the right distance, you'll see a little image of the screen on the paper. Just like cameras, your eye has a lens which focuses an image of the screen onto your retina. The top of the screen ends up apart from the bottom. The left is distinct from the right. It's all done with lenses.

Why do certain shots hurt more and for a longer time than others?

The three main routes are intradermal injection, subcutaneous injection and intramuscular injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. IM causes painful bruising because the needle is going into your muscle.

Garden centres and pet shops have dirt cheap "bird feed" peanuts. Why can't I eat these instead of regular grocery peanuts?
|
You can. I grew up in a pet shop family and ate tons of bird seed seeds and even dog treats. I would check the country of origin on the label though, as some countries may use pesticides that you want to avoid.Food products like seeds and nuts that aren't meant for human consumption may be processed in ways that make them unsafe to eat. Wild bird/animal feeds are sometimes treated with chemicals that make them safe to store for long periods of time or to eliminate any insects/pests that may be present in the grains/seeds/nuts. Many of these products can be pretty nasty if consumed by humans. Considering that many of these products are now imported from countries that don't have the best track record in terms of food safety to begin with, you're taking an uneccesary risk by consuming them. I'd think twice before doing so if I were you.They are likely treated with non food safe chemicals like fungicides that make them much cheaper to store and handle but not suitable for human consumption.

Why is it bad that the 85 richest people on the planet are worth nearly as much as the poorest 50 percent of the world's population? [Serious]

It's not bad if you take advantage of the situation and think smart. If rich people have more money then half the world you start a billionaire protection service, complete with drones/cyber-shielding/etc and military veterans. Sounds like they are gonna need it. Oh and if you do, make me a VP or something. Don't let a brother go broke. ;)

As I am falling asleep, why do I see images and hear sounds that are almost like hallucinations, and how do they differ from normal dreaming?
|
It's called hypnagogia. As you transition from awake to asleep, you pass through a weird bit where it is possible for bits of dream to get mixed in with external sensations, and/or for lingering bits of external sensations to get mixed into your dreams. This experience of dreamstuff while not entirely asleep can make you feel like something is not right, as the waking and dreaming worlds are often governed by different rules. But it can also be pleasant - Edgar Allen 'Night-Pain' Poe was a big fan of hypnagogic hallucinations, which he mined for story ideas.

Where do our eyes focus when we close them?
|
The eye focuses on light, and thus when you close your eyes the muscle involved, the cillary muscle, relaxesI was taught that with the eyes closed they tend to focus at about 1 Diopter or about 1 meter from youI remember that when we were messing with our buddies during a summer-camp by opening their eyes in their sleep their eyes were rolled up all the way to the top of the holesI think about 1 relaxed armlength away. Close one eye and try to relax the muscles for focus. For me my hand is in focus than. Seems plausible to me, that the resting focus is where you focus most often

If you are referring to car tires, a bald tire does have more traction but only when dry, street cars need the treads because it isn't going to have the ideal conditions a track car would have.

How come there is so much money in golf? Tiger Woods is arguably the best paid athlete, yet no one I know watches golf, and neither has golf big stadiums like football.
|
It's about who the audience is. Advertisers and sponsors are OK with decreasing the number of consumers if they can reach a richer audience. Golf is more of a sport for the richer set whereas football is more of a sport for working class people.Endorsements, & sponsoships play a huge role. Also, I have seen Tiger Woods play in person and there are hundreds of people there watching as well. Not just Tiger but other players have a following too. Plus, the tickets are pricier than a football/baseball game.> Neither has golf big stadiums like football. That doesn't mean events aren't well attended. The [TPC Stadium Course] in Scottsdale, AZ is the home of the yearly [Phoenix Open]. Each year, they [attract over 500,000 people] to the event. It's home to the [16th hole] a fully enclosed hole with stands surrounding it. To get this back to Tiger, he had a [hole in one] at the 16th hole.
|
When I call someone, why is the first ring always louder than subsequent rings?
|
This is probably due to sensory adaptation. When you experience something that triggers one of your senses multiple times in a row, the experience is less and less each time. This is also why you get used to smells.
|
Why do the veins on my arms become less apparent when it is cold? But more apparent when it is hotter or I am doing physical labor?
|
This is part of your thermoregulation system. When it's hot, your body pumps more blood to veins near the surface in order to radiate heat from it. Likewise, when it's cold, blood is withdrawn from the surface to keep it warm.

Why does "the big red car" sound better than "the red big car" in the English language?
|
Because adjectives have a specific order in English . The order of adjectives in English is > Quantity or number. > Quality or opinion. > Size. > Age. > Shape. > Color. > Proper adjective > Purpose or qualifier. As you can see size comes before colorBecause different languages have different adjectival orders. The rules surrounding this are kind of complicated and sometimes not that set in stone. But as you mention it just sounds wrong if you try to put them out of order. [I think this video explains it quite well]

Why is there no cure for rabies?
|
rabies has a vaccine called rabies post exposure prophylaxis or RPEP. after being bit, they can give this with antibodies for rabies at the bite site. so you can cure it, it depends on the animal bite scenario if youre given RPEP where your confusion comes into play is youre used to the idea of healthcare being after you show symptoms. In the case of rabies, the cure is before you show symptoms. This is because if you're foaming at the mouth you will die since the virus is already in your brain at this point There have been some cases of people who have lived after showing signs of rabies, at least one of them if not all were induced into coma. this is more of a last resort no other option kind of deal i imagine

Why does adhd medicine calm people with adhd down and speed everyone else up?
|
ADHD medication does "speed up" the brains of people with ADHD; what looks like "calming them down" is really more like "speeding up the part of the brain responsible for staying focused."As a person who took Adderall for 6 years of their childhood; it seems like it calms down children but has the opposite effect on adults. It calmed me until I was about 16, then it started doing the opposite.

Is being disgusted by fat people just social conditioning, or is there more to it?
|
It's a combination of biology and social condition. Biologically, we are coded to find attributes of the opposite sex that we perceive as an indication of fertility and ability to raise a child. In women that means wide hips , large breasts , and general fitness , and physical symmetry . In men that usually means physical size & fitness , intelligence , wealth , and physical symmetry . So, we are naturally drawn to women with a healthy hourglass shape and men with a large, lean build. However, social constructs do have their part. For instance, how do you measure intelligence or wealth? In the olden days, over-weight people were actually found to be attractive because it was a sign that they did not work a manual labor job and they had the means to properly feed a family . That perception of over-weight people lasted as long as food scarcity did. However, these days, food scarcity is a thing of the past, so we gravitate towards people who exhibit "superior" genetic traits, or as well call it today, beauty.I doubt you'll find much people that are truly 'disgusted' by fat people. Most people are rather judgmental but not really 'disgusted' by it.

Instead of aiding fleeing refugees, why not make them stay and fix their own governments/countries?
|
First of all, Canada is only committed to taking 25,000 refugees. That couldn't even take Rogers Arena, let alone a nation. For perspective, Assad has ten times that many political prisoners already, and the US government has released evidence that he tortured to death half that many people since 2011. Syria is an unwinnable scenario. There's a reason that no Western power has put boots on the ground there. While its possible to defeat ISIS if they side with Assad, all of the evidence is that, if you actually live in Syria, Assad is just as bad as ISIS. There are no good guys left to fight for there - just two villains. The nation of Syria is simply lost. It will be decades before it can be reclaimed, and only after the Russians lose interest in it.I'm going to remove this as a loaded question. Canada isn't going to be flooded with "such a massive number of refugees that could overturn an oppressive regime". If you want to argue 25k people could try /r/changemyview.I don't think you realize how little 25,000 people is. Especially in regards to overthrow a regime. The average hockey game in Canada has what, 15,000 to 25,000 people in the arena?

Einstein's Theory of Relativity and a phone call going across the galaxy

Ok, as simple as I can explain it. Time slows down the closer you get to the speed of light, but only from an outside observer's perspective. So, if I'm on a spaceship travelling near the speed of light and you're on a planet watching me fly by to you, time is passing normally and I'm in slow motion. To me, time is travelling normally and you're in 'fast motion'. So, to answer your question, if you called your friend on planet X, everything you said would sound slowed down, and the call would last 3 years. If he stayed on that long, he would sound like he was talking insanely fast. Basically, anything that you took a minute to say would be stretched out to where it would take about a week for him to hear .and if he talked for a minute, you'd hear that in about 1/62,000th of a second.

Why don't razor/shaving cream companies push for men to shave leg hair? Wouldn't that increase their market and profits?
|
There is also a risk of a backfire.. If they push it too aggressively, then the brand may be seen as feminine by a large part of the target group. As you might have noticed, portraying a macho image with male-grooming items is seen as important in advertising.It's just a guess, but I imagine they've done market research which proves this would not be a popular product with men.

Why do a lot of people(might be subjective) think Keanu Reeves is a bad actor?
|
His range of acting is said to be really limited, you generally know the general sense of his characters before going to a movie. Personally, I think he is the person for those roles. No one plays his type better than he does. I can't imagine anyone else has Neo, I know other actors would have their own variation, but his lack of emotion in acting in a virtual world run by machines captured the feel of that works for me.

How is the present defined with respect to the space-time continuum?
|
In relativistic physics, which events are simultaneous depends on the observer looking at the events. So every observer has their own present and if different observers are travelling at high speeds relative to one another they'll disagree about which events are in the past, present and future.
|
how do zero acceleration and zero velocity work?
|
Yes, acceleration is when there's no change in velocity. Zero velocity is when there's no change in position . But velocity is a bit weird in that's it's kinda arbitrary. It needs to be relative to something. So it's perfectly legitimate to say that you are moving at 0 m/s, or 10000 m/s, as long as it's less than the speed of light.

Why can't I have a wild bird like a cardinal or a jay as a pet?
|
Being undomesticated, they retain the wild, primitive instincts of their velociraptor forebears. Eventually, the impulse to roam and horrifically mangle secondary characters without actually appearing in-frame will prove too much and they'll get loose. After that, it will only be a matter of time before they learn to work your doorknobs and you wake up to them eating your face. So basically what was already said.

What is the difference between "Equal" and "Stretch" tuning for pianos
|
In general it has to do with how far apart an ocative truly is .central A oscillates at 440 oscillations per second. One ocative in equal tuning would be doubled or halved that so the A above is at 220 oscillations and the one below is at 880 oscillations. In stretched tunings that is changed or "stretched" so that the ratio isn't doubling, but slightly more than doubling . It is usually only done with non digital electric pianos like Rhodes and Wurlitzer.

why is a fisheye camera lense typically used in skateboard videos?
|
The most important aspect of the fisheye lense is that it is wide angle. So much so that careful framing is not too important. Also, the wide angle minimizes jerkiness and vibrations. Then, you can have your cameraman chase after you while moving at speed, jumping and shit without needing a dolly or big steadicam rigA wide angle lens gives things the perception of moving faster than a normal lens does. It also lets you get really close to something while still capturing the whole object in the field of view, which is typically how these videos are filmed.

Fruit flies....how FAR can they be 'forcibly evolved' in a lab?
|
They 've been bred to the point where they weren't able to reproduce with other fruit flies. That's commonly considered a new "species". It would probably take too long to turn it into something very very different.

Why does a processor, for computers, get so hot? How doesn't it just melt? How does a fan and a heatsink work so well?
|
There's an enormous amount of work happening in a tiny amount of space. Under load, CPUs use huge amounts of electricity, which generates heat. The heat in the CPU can be controlled with a fan because, while it's very hot, it's also a very tiny area. So the total amount of heat-energy that needs to be removed is quite small. Heat sinks have a huge surface area and are made of material that conducts heat very well. So the heat-energy is moved from a tiny space to a huge space , and then quickly moved away with a fan.

If the vast majority of video cameras and websites support HD video nowadays, why is the porn industry still flooded with low definition videos?
|
My best guess would be that they want you to subscribe for the higher quality/full length content. Why give away your best product for free right?

Knights and knaves logic puzzles
|
Lots start by seeing if person 1 is a knight? He said that both people are knights. If that was true, person 2, being a knight , would have to tell the truth. But he said that person 1 is a knave. There is no possible way for person 1 to be telling the truth. So if person 1 is not telling the truth, he's a knave. Well, that's what person 2 said. If person 2 was a knave he couldn't say that, because knaves always lie. He must be a knight. Solution: person 1 is a knave, person 2 is a knight. Edit: damn, beaten to the answer by two minutes! I do enjoy these kinds of puzzles!

How do rush hour traffic jams form?
|
Traffic is like pouring milk through a funnel. If you pour more into the top than can escape through the bottom, the milk fills up the funnel and overflows. Only so much milk can move through the bottom of the funnel, and pouring more into the top doesn't make it move through any faster. But, a road is like a super long funnel which doesn't spill it just gets more and more full. Every car entering the road fills it up more. Once we slow down how much we pour in, the funnel can begin to empty again.A lot of the problem is caused just by the volume of traffic on the roadway. As more and more cars are on the road, cars end up being more tightly packed. When this happens, if a car brakes slightly, the car behind it brakes possibly harder in response and this gets amplified extensively until you get sections of stop and go traffic on a roadway

Why is the 1/4 mile stretch and 0 to 60 the benchmark cars are rated for?
|
The European standard for measuring acceleration is the time for 0-100 *kilometers* per hour. This is converts to about 0-62mph which was then rounded down, so both numbers are very similar and can be easily compared. The quarter mile seems to come from quarter horse racing ), but I figure that this is just a good distance that is not too short and not too long .0-60 MPH is a bit more relevant than 0-100 MPH because it is a greater indicator of torque at low speeds.Some cars are unable to get to 100? And 60 is a speed that's legal on highways pretty much all over the world. In Europe they mostly test 0-100kph . A 1/4 mile is the usual run for drag racing, which I believe is due to the length of the runways when they first started drag racing.

Why/ How are celebrities insuring their body parts!? And what does said insurance actually cover!
|
Celebrities do it because there are certain parts of their body or features that are important to the line of work they do or get people interested. For example, pornstar Kieran Lee insures his member for $1 million as his member is the only way he can earn an income thus if anything happens to it, the insurance company pays out.For the second part of what they actually cover. It can be anything that you sign on. Say you're a professional pianist, you would want to insure your hands because without your hands you are worthless. Youll have to decide what kind of injuries the insurance will pay for. Common injuries will be more expensive. You will also have to let them know your other actives. It will be more expensive to get insurance if you also enjoyed partaking in MMA since you are more at risk to injury.For the how, you can basically insure everything. Approach an insurance company that deals in the "body parts" insurance business. state the body part, and the price you insure it for. They calculate the odds something actually happens to it, use those odds to determine how much the insurance rate is that nets them a good profit. and viola.If my trademark is my mustache, I'll ensure it so that if something were to happen to it, I'd still have an income even though I'm losing work because no one wants to see me in a movie with out it.

Why did George Lucas need an actor inside of R2D2?
|
Robotics in 1976 was primitive. The guy turned the top and made R2 wiggle the right way. This was way better than any robotics could have done without spending way more. I am certain that part of R2's personality and charm actually came from having a person in there doing some moves.Electronics, radio controls and actuators were expensive and not very easy to handle and required more men on an already crowded set. It was much cheaper to put a dwarf in a robot suit then to build a remotely controlled robot.

Do flightless birds still have hollow bones?
|
It depends on the bird in question! Hollow bones are the ancestral characteristic in all modern birds, but more interestingly they go back *much* further than the evolution of avian flight, right through to [theropod dinosaurs] and even [sauropods] ). Having evolved for reasons other than flight, there's no immediate reason to therefore suspect a loss of flight should necessary also result in a loss of this trait. Which perhaps is why most modern flightless birds still retain theirs - particularly all those recently flightless from isolation on islands; flightless cormorants, rails and the like. Some groups have lost this trait for reasons other than flight too; say, to reduce buoyancy and aid diving. Penguins have solid bones and don't fly, but related grebes, loons and other aquatic birds have solid bones yet still fly ). This perhaps answers your question at least with respect to penguins; they evolved more solidified bones first, to aid with diving, and lost flight thereafter as a consequence of both this and reduction in wing size, rendering adventures in the sky too energetically costly , [source #2]). Ostriches and other ratites have a mix of the two. Most of their bones are hollow, but many found in their legs are are solidified, filled with a thick cortex to help support their great bulk , indicating adaptation post-flightlessness. So yup, it depends! In any case, it seems more solidified bones come about for reasons largely independent of flightlessness *per se* though.

why drinking alcohol would/wouldn't help with food poisoning or other type of infection in the GI tract.
|
If you were drinking enough alcohol to sterilize your GI tract you'd probably have other problems more serious than gastroenteritis or whatever you had.
