Why do online videos un-buffer when you rewind them?	[ "YouTube started doing this a while ago, many people would pre-load minutes/hours of content without ever watching it, which is wasting YouTube's bandwidth. So, they now only stream video in segments, like 5-sec each. As for why the already played content isn't cached on your browser, these sites simply didn't allo...
Where did the idea for blue raspberry come from?	[ "There are actual fruits called blue raspberries, but they really look more purple or black (not to be confused with blackberries which are related but different).\n\nThe bright blue color mostly came about to avoid having another red-colored flavor, since that color was already associated with cherry, strawberry, ...
If Apple slows down older iPhone models when the battery can’t keep up with the processor, then why are they still slow when plugged in?	[ "Whilst its true that switching the iPhone to 100% mains power would alleviate any power stability concerns, allowing the processor to switch to full power, in practise, the mains power charges the battery, and then the processor draws from the battery. This arrangement allows for the phone to be unplugged suddenly...
How do paintings become so valuable?	[ "You know who is into paintings? Rich people. They are happy to pay a huge amount for these works of art they (or the art world) consider great, the money isn't a big deal to them, and often they are bought as investments to sell at a later date (art almost always goes up in value).\n\nWhen the people who want it a...

Why is "XXX" associated with sex, nudity, and porn?	[ "The movie ratings organizations used to have an \"X\" rating for movies that were above and beyond \"R\" rated.\n\nIIRC, this has since been changed to NC17.\n\nBecause X rated was associated with explicit scenes (though this included violence, not just nudity), it became a positive marketing point for pornografic...
the difference between DVD+R and DVD-R	[ "DVD-R and DVD+R are just two different ways disc players read data from the disc. DVD+R is newer than DVD-R and uses new techniques to prevent discs from malfunctioning as often when the disc is being read. DVD+R is also better at reading data from scratched discs. What you heard is probably a good rule to follow ...
If large corporations aren't paying their taxes, why do we still get taxed on their products?	[ "Sales tax is separate from the corporate income tax. The sales tax is applied at the register and then the store sends that to the state. Then, in an unrelated event, the corporation pays taxes on their income (which they make from selling the product to stores, not when the store sells the product to you).", ...
The Effect of barrel length on a gun	[ "There are several important effects of barrel length, some of which depend on what weapon you're considering.\n\nFor a handgun (pistol or revolver):\n\n* A longer barrel increases the muzzle velocity, because the combustion gases have longer to push on the back of the bullet as it exits the barrel.\n\n* A longer b...

Why do malls and businesses not have peaked roofs like you see on houses?

Why do leftovers make a popping noise while being warmed up in the microwave?	[ "Microwaves work by exciting water molecules in foods. \nSo if you recall there was a commercial years ago of Velveeta and a popsicle being heated in the microwave. The cheese melts first. \nThe water molecules in ice are locked in place pretty tightly. \n\nWhen heating up food the water heats up more in some spots...
If an older person is wealthy.. would it not be wiser for them to distribute some of that wealth the way they want BEFORE they die?	[ "Yes. It's very common to do this. There are lawyers and accountants who specialize in it.\n\nIt's not a magic pill. You can't give unlimited gifts to people without paying taxes, because to the government, that looks really suspicious. If I remember correctly, the present rules in the US are, you can give individu...
Is the existence of light NECESSARILY paired with heat, or is it just that that's how we've always observed it?	[ "Pretty much everything is necessarily paired with heat, just because of how the universe is. Heat is basically just random motion, and since nothing's perfect, there's always energy that gets \"wasted\" in the form of heat when you try to do something.\n\nIn theory, though, yes, you can produce light without gener...
Why incandescent lightbulbs are bad. And CFL bulbs are good.	[ "I can't find anything showing how much CFLs are still subsidized (if at all) by the government. Everything recent-ish that references CFL subsidies talk about the power companies themselves subsidizing them.\n\nAlso, the video is misleading about at least one thing: incandescent bulbs are not being completely ba...
Where did the easter-bunny come from?	[ "Spring is the season of rebirth. The pagans celebrated this by honoring their goddess of fertility named Eastre. The symbols of fertility for the pagans were bunnies and eggs. The pagans emigrated and spread their religion. Germany took the bunny image and combined it with their freaky Oschter Haws bunny that left...
What is with the sometime hours and hours or delay in having sore/dead/tired legs after over doing and pushing yourself with leg exercise/walking/running?	[ "I believe it's somewhat to do with DOMS (Delayed Onset Muscle Soreness), in which your body begins to repair tiny microtears in the muscle fibres of your legs after long periods of exertion.\n\nDoing this makes your legs stronger and able to endure more physical activity. It's like how people build muscle in the g...
Why is the voting system in the USA so suboptimal?	[ "It's because it is really old. compared to most modern democracies the US system is almost ancient. And new technologies allowed for new (better) ways to handle the voting process.\n\nAlso society changed. Many nations like France or Germany who \"updated\" their type of government after world war 2 decided agains...
Why are car rides soothing for babies?	[ "Some people will say it's because the car environment reminds babies of the womb. That may be true. It's not a testable hypothesis, though.\n\nThe noise and vibration of the car's engine create a monotonous sound and vibration that allow a baby to relax; there is nothing new to see, hear, feel, or do because the c...
What makes duck fat so special?	[ "Duck fat simply has more flavour to begin with, any fat that you use to cook something will impart a level of flavour into whatever you cook with it.

Why don't wind farms have bigger sails to collect more energy?	[ "The blades of a turbine are not designed to catch wind. If they caught the wind, the turbine would be blown over by it.\n\nInstead, they are designed to be turned by the wind.

Why do you feel faint after standing in the hot shower too long?	[ "Most probably this happens due to having low blood pressure. Hot water (heat in general actually) raises your body temperature and then our termoregulation mechanics kick in. One of that mechanism is to vasodilate our arteries in order to widen the contact of the artery with the surface of the skin in order to los...
Why do some martial artists yell in movies and at demonstrations?	[ "There are many reasons. Exhaling tightens the diaphragm and tenses the body, making strikes more powerful and protects the body from counterstrikes. This is why UFC fighters always make that \"tsss\" sound whenever they throw a strike.\n\nI am also fairly sure that yelling has to do with rituals used by martial ar...
Why do we still require signatures when they can be easily forged? Wouldn't fingerprints be a more foolproof way of limiting ID theft?	[ "Mostly just because courts and others have long agreed that signatures are good enough, they for the most part haven't totally accepted other things for legal documents.\n\nAlso, from a legal perspective, the difficulty in recreating it isn't that much of an issue, it's the source that ultimately matters, not the ...
How does Pope Francis differ in any substantive way from his recent predecessors?	[ "Pope Francis has spoken out against the greed culture of capitalism.

why did the universe not just immediately collapse into a blackhole?	[ "The matter and energy in the early universe was extremely smoothly distributed. If it had been lumpier, certain regions would've collapsed into black holes, but because the matter was so smoothly distributed the outwards pull was equal to the inwards pull, preventing a collapse\n\nIn fact, the reason any regions c...
how can sites like _URL_0_ sell domains? do they buy them? if so from who?	[ "they are authorized by ICANN, the organization which controls the domain name system.

What is LiveLeak and why is it a thing?	[ "Its like a YouTube without censorship.

H.P Lovecraft fanaticism and cult following	[ "* An author who wrote pretty much only short stories set in New England and involving horror and mystery elements.\n\n* Those short stories are quite good, especially at capturing fear of the unknown.\n\n* The Call of Cthulhu influenced much of sci-fi design when it comes to \"terror from the great beyond\" style ...
is the concept of light speed defined by light itself, or does light just want to go infinitely fast but physics puts a cap on it?	[ "As far as we know, it's the second one. Particles with no mass travel as fast as physics allows anything to travel. Since photons are the massless particles that we encounter most often, we first encountered that maximum speed by observing light and we called that speed \"the speed of light\".", "Light is fast, ...
How can parents keep adoptions secret from the adopted while in movies and TV shows it is shown that an 'officer' or overwatcher takes weekly/monthly visits to check if everything is alright??	[ "There are not officers or over-watchers who check on adopted children weekly or monthly. You are confusing a child who is in foster care with one who is adopted.

What exactly happens when I poison an ant colony?	[ "Ants have different jobs. Some of the worker ants bring food to the queen and move the eggs around.

The ones who would be really sad about a dead queen are the drones whose job it is to mate with the queen....
Why doesn't the ruling that The Patriots were deflating their footballs negate their superbowl win?	[ "Tom Brady playing with his balls doesn't necessarily mean that the rest of the roster needs to be punished as well.\n\nThe NCAA is a fan of vacating wins and titles, but that's extremely rare in the pro leagues. MLB teams don't lose old wins due to steroid allegations either.", "They weren't caught cheating in ...
Why flies fly around people's faces and bump into them like on purpose?	[ "Flies don't intend it, they're just looking for food. They mainly navigate by smell, and a very basic sense of sight. \n\nYou smell like organic stuff.

Does it take the same amount of gas to keep my home (or commercial building) heated to 65 degrees as it would at 45 degrees?	[ "Even if you have the best insulation possible, there is always going to be some heat loss. The greater the difference between the heated inside and the cold outside, the faster the heat will leave. So it takes more energy to maintain the higher temperature.\n\nThe key thing here is the difference between the insid...
Why US public universities are so expensive compared to many (all?) European countries	[ "In the UK the government sets the maximum amount that can be charged for an undergraduate degree per year.

Market forces means the university charges what...
What does "pass-through" mean?	[ "Also if the company is an LLC, then it doesn't pay taxes on the revenue.

If GPUs are so powerful, why do we not simply replace CPUs with them?	[ "Because GPUs are good at a specific type of computation: namely highly parallelized simple tasks. They have hundreds or thousands of \"stream processors\" that handle small simple tasks (like rendering pixels) all independent of other pixels.\n\nCPUs are meant to be more generalized and handle complex single thr...
why cant we spell out words phonetically?	[ "As I understand it:\nThe main reason is because of the different languages English arose from. We borrowed some words from Latin, some from Greek, some from German, etc., and as a result, our spellings often seem weird and nonintuitive.", "English has always borrowed lots of words from different languages. The ...
Why do people like politicians announce that they'll announce something, rather than just announce it?

Why no IVF after a vasectomy?	[ "It's a tradeoff. You need to compare the costs of collecting and freezing sperm samples for the years between your vasectomy and the time you want kids to the cost of what you propose. At $150/year to store sperm, the math doesn't check on other procedures." ]
How do rooms end up covered in dust if no-one uses them?	[ "> Dust consists of particles in the atmosphere that come from various sources such as soil dust lifted up by wind (an Aeolian process), volcanic eruptions, and pollution.

Why cities didn't deveop a pipe network to collect rubbish, like there are sewerage and water pipes?	[ "Economics and physics.\n\nRubbish isn't a fluid.

The steampunk genre (I just don't understand.)	[ "Science fiction set in a sort of alternate Victorian Britain.

What if humans were raised to sleep during the day and be awake at night, would we ultimately evolve and become nocturnal?	[ "Being raised to sleep during the day and be awake at night would be an acquired trait, and when you give birth to someone, DNA is passed down, not acquired traits.\nAnother example of an acquired trait is strength.

How exactly did scientists work out the speed of light?	[ "At first people thought light traveled infinitely fast. Then in 1676 [a Danish astronomer](_URL_0_) showed that it didn't.

Does alcohol taste better for adults tha it does for kids? if so, why?	[ "In some ways. \n\nBefore puberty the sensitivity to bitter is much much higher than it is after.

Why does society often associate wearing glasses to being smart?	[ "There is a correlation between long hours of study as a child and nearsightedness.

The amount of electrical power (energy over time) is the current multiplied by the voltage.\n\nSo, that means ...
The US is training Syrian rebels to fight ISIS. We call them "fighters" why? Why don't we call them "soldiers"?	[ "They're learning fighting tactics, not structure and regulation.
