How did television in North-America evolve to a situation where people are paying 50 dollars a month to watch little 15 minutes segments interrupted by ads.
|
[
"That's why cable is dying. They used to have monopolies, more or less, but that changed with the internet."
] |
[
"Maybe the reason why these paid apps exists is because people are sick and tired of ads interrupting the content that want to watch to show them the same ad for a truck that was shown 5 minutes ago."

If botox is the most lethal substance known to man, how and why do we use it for cosmetic surgery?
|
[
"its all about controlled dosage. understanding how long it remains active in the system. Spacing injections both by time and location to stay within safe margins. The concentration of Botox injected in patients is around 0.75 ng per 100 units, or roughly 1/5 of the estimated lethal dose in humans. Typical injection of 4 units. 20-30 units per session. 360 units per 36 month period is the recommended limit."

How does Winamp generate its visualisations?
|
[
"With the raw audio data, you will only get the loudness of the audio at a specific point in time (or for a range) If you analyze/convert the raw data using [Fourier Transform](_URL_0_), you can calculate which frequencies are used and how strong (power) those frequencies are. This can be done in real-time using a method known as Fast Fourier Transform (FFT). You then use this data to build your visuals, for example low frequencies can be darker colours as opposed to mid to higher frequencies. I wrote a [web demo](_URL_1_) a while back. Unfortunately, it requires Microsoft Silverlight to work (I was experimenting with Silverlight audio)"

Why a doctor would prescribe the name brand for a drug over the generic.
|
[
"Perhaps the doctor is more familiar with the brand name. But the pharmacist will be familiar with both names, and you can save some money (sometimes, a *lot* of money) by asking the pharmacist to fill the prescription with the generic. Pharmacies in the US will typically have a sign posted that reads as follows: \"THIS PHARMACY MAY BE ABLE TO SUBSTITUTE A LESS EXPENSIVE DRUG PRODUCT WHICH IS THERAPEUTICALLY EQUIVALENT TO THE ONE PRESCRIBED BY YOUR DOCTOR UNLESS YOU DO NOT APPROVE.\""

How does Data capping effect Gamers?
|
[
"The data required to play video games is quite small compared to the amount of data needed to stream video. The bigger issue that data download caps have on gamers is for downloading the digital versions of games and the resulting patches. Games nowadays are approaching the limits of Bluray disks (50 GB). Star Citizen supposedly will have a [100 GB client](_URL_1_). Even if you do not download the digital version of games, video game patches are getting quite large as well. [The Witcher 3's 1.1 patch came in at 15 GB](_URL_0_). If you have a library of many games, just downloading the patches over the span of a month will push you towards your download cap. Lastly, in terms of live-streams, you are generally uploading data rather than downloading. I'm not sure if it counts against the download cap but it should be at roughly the same data rate as someone viewing the stream."

Why are Uber and Lyft fighting regulations they put in place (i.e. fingerprinting in Houston and Austin)?
|
[
"Because all these regulations being proposed increase costs and make it more of a hassle to get drivers and passengers. Uber and Lyft are mostly successful due to lack of regulation on services like theirs... once regulation starts to catch up they'll be no better off than Taxis and they lose their competitive pricing edge. So they're going to want to fight any regulations people try to put on them"
] |
[
"Because Uber doesn't operate as a cab company, they operate as a ride sharing service, meaning the drivers are not cab drivers. This means Uber and the drivers can get away with not getting the licenses and insurance that cab companies and drivers are required to have."

Why can't people withdraw their money from a bank that goes bankrupt? Specifically those regular savings accounts? That supposedly have no such risk as it's a saving, not an investment.
|
[
"Any money you put into a bank they use to lend to others. If they go bankrupt then they have absolutely nothing left and your money is gone"
] |
[
"There's a few ways 1) Loan interest: Bank's loan money, people pay back much more then they loaned in the form on monthly payments. 2) Partial investments (primary money): A bank doesn't have all of your money sitting in its vault. A bank only keeps ~5% of its total cash on hand at any given time, this is because most of its money is invested in hedgefunds, stocks, bonds, etc. Where's its making more money for the bank. Now this works because normally accounts have a minimum deposit, or in your terms of service it will say you can't withdrawn more then 10 grand in cash at once. This is also why the FDIC exists, which is federal bank insurance pretty much. During the great depression people kept their money in banks which were invested in the stock markets, the banks 'failed' because they lost most their cash assets in the market crash meaning they couldn't give people all the money in their accounts which is the definition of a failing bank."

Why do we only start to see fog yards away from where we are standing and not at our feet?
|
[
"If fog is very very thick, you can see it at your feet. The nature of fog is that you can see through some of it but not all of it (that is, some but not all light passes through). So, when you don't see it at your feet, it's because you're seeing *through* the stuff that is at your feet. You *can* see it farther away because you've looked through enough of it to notice the effect. Basically, fog scatters light. If it's not super thick, you must look through a few yards of it to notice that the light is being scattered. Either that or it's made of spirits who can't stand to be in contact with living beings so they stay away from you."

if two different phones/tablets/computers are running the exact same OS, how is it possible that one device can experience a bug/glitch but not the other device when performing the exact same task?
|
[
"1: A mechanical defect in the device. This could be something as large as a bad piece of solder on a board to as small as an actual defect in a chip, or anything in between. 2: Random cosmic ray strike. High energy particles from space can hit sensitive electronics and \"flip\" a bit from a 1 to a 0 or vice versa, changing the software encoded by that bit. 3: User error. Causes too numerous to enumerate. 4: Corruption of data. During the process of downloading and installing the software an error was introduced which was not detected by the error-checking schemes. Could have been caused by random transient currents in the wires, by errors or misconfigurations of devices in the network, etc."
] |
[
"Computer programs ALWAYS have bugs, it's the nature of programming as software is usually so complicated with thousands upon thousands of lines of code, some situations weren't thought about or someone just made a mistake when making it. Little bugs often exist that cause programs to become unstable over time, and there isn't anything built into the software to detect that it's unstable and fix the problem on it's own. Restarting the program clears out everything and starts fresh, as it was before it got into that unstable state. As far as restarting your computer, everything on your computer is software, and is included in the above description including your operating system (windows, mac, linux) and your drivers which are software that lets your operating system talk to the hardware and accessories it's working with."

Why can't/shouldn't we go back to the gold standard?
|
[
"Gold is a luxury item. Only 10% of gold is used for manufacturing or technical purposes, the rest is used in vanity goods like jewelry or hoarded as an investment. Therefor, its value is perceived rather than practical, and as such the price is subject to whims. (See: gold rising to insane levels as people fear an economic meltdown.) By basing your currency on the stability of your government rather than a finite resource, you open up a lot more flexibility in terms of monetary policy. Also, since governments generally move slow and avoid drastic measures, the value of the currency remains relatively stable over long periods of time, which commodities like gold and oil do not. Short version: Businesses like it when the value of a dollar is stable. It's a lot harder to maintain stability if your currency is tied to a finite resource."

What is the Raspberry Pi? How can a computer cost 5$ while mainstream computers can cost up to 2000$?
|
[
"The Raspberry Pi is a very small, lower power, lower complexity computer. Because they have sold, and will continue to sell many, they can afford to get parts at bulk pricing. The RPi $5 board is also so much smaller and stripped back compared to the ones that cost a few times more than that. There's also the fact that it doesn't have a keyboard, mouse, monitor, or any of the other trappings that one conventionally associates with the word \"computer\". It's like you're buying a very stripped motherboard. Price a motherboard similar to the one in a $500 desktop and see how much it costs. Also, no OS is included. You also have to provide a lot more work to get the thing to even work. A $500 HP works out of the box with little setup or wiring. A $5 RPi requires you to wire a bunch of stuff to it, buy an enclosure, a microSD card, and spend time setting up an OS to work on it."

How are 300 calories in a donut different than 300 calories in a burger?
|
[
"There's far more qualified people than me who can break this down, but I can give you a somewhat close answer. Basically 300 calories is 300 calories. Let's assume you burn 2000 calories a day. You could eat 1500 calories worth of McDonald's and lose weight. You'd gain fat and lose muscle and have a bunch of health issues, but that number on the scale would drop. Or you could eat 1500 worth of vegetables fruits healthy fats and lean meat, you'd build muscle and lose fat, and the number on the scale would still go down. There's fine tuning people do, for exactly how much protein or carbs or healthy fats they can eat to maximize their diet. Basically you eat less than you burn, you lose weight no matter if it's fat or muscle. You eat more than you burn and you gain. *What* you eat determines if your body is going to burn that fat instead of muscle or not."

Why a wheel turning at high speed appears to be turning the other way round?
|
[
"If you take a basic wall clock and watch the minute hand, it moves very slowly, doing one rotation every 60 minutes. However, if you take a camera, and leave it to take a picture of the clock every hour, and watch those pictures like a movie, you'll think it doesn't move at all. Now take that camera and make it take a picture every 61 minutes. Every picture it takes, the minute hand will have an extra minute to move, so will have gone slightly around the clock. Do it the other way around, and take a picture every 59 minutes. Even though it has moved forward, it looks like it has only moved back a little bit. Basically a similar thing is happening between your eye and the wheel at a significantly faster rate. Your eye is a bit trickier than just taking a photo on a regular basis, but the basic principles here are more or less the same."

"Imagine you're in the middle of a carousel with a ball in your hand. Your friend is facing you by the edge. The carousel starts spinning clockwise. You throw the ball in a straight line towards your friend. But because the carousel is spinning, your friend has actually moved in space and the ball looks like it curved to his right (your left). The ball did in fact go in a straight line in space (someone not on a carousel can see it) but from your and your friend's frame of reference, it looked like it curved. Gif: _URL_0_ Now you can apply this to the Earth which rotates just like a carousel, just a lot bigger and a lot slower in terms of RPMs. Therefore the Coriolis effect is really weak and only strong enough to heavily influence slow moving systems like weather systems. It's the reason why storm systems in the Northern Hemisphere rotate clockwise and counterclockwise in the Southern Hemisphere."

"Basically it's an encryption scheme where you can perform operations on the encrypted data and get a result that when decrypted using the same method as decrypting the source data will result in the same output as if those operations had been performed on the original unencrypted data.

This is in contrast to conventional schemes where the party doing the processing needs to have an unencrypted copy of the data, inherently reducing the security of the whole process."

As long as cuts heal like new (not offset in any way) then the lines/edges shouldn't be disturbed, except for distortions due to scar tissue. If a tattoo gets scraped or cut, treat it like you would a freshly inked tattoo, so as to prevent any scarring or fading. Don't pick at the scabs and just let it heal.

"You know how a school bully might threaten to beat you up if you don't give him your lunch money? Governor Perry is accused of doing sort of the same thing by threatening to not give a woman's department money if she didn't resign from office. Since it was the governor doing it, he should know better. This would be the same as your school principal demanding that you give him your lunch money or he'll make sure you fail all your classes. School districts don't like it when principals do that, and grand juries don't like it when governors do that."

How do ships stay afloat even when carrying thousands of tons of cargo?
|
[
"By displacing more tons of water than the ship+cargo weighs. That's why they have to be so strong, to keep enough water out."
] |
[
"The same way that they build bridges for cars and trains, with a few differences. Firstly, the bridges are designed to hold up more weight per square foot than other bridges, to compensate for the weight of water. The interesting thing about these bridges is that changing weight loads is less of a factor than bridges designed for other purposes. Because boats displace an equal amount of water, the bridge holds roughly the same weight when no ships are passing as it would if a full tanker passed over it."

Why have bones evolved to heal so slowly, or why do they heal at all? Wouldn't any animal with a broken bone likely die in the wild of something before the bone was healed?
|
[
"Evolution is still limited by physics and chemistry, and each feature is a balancing act with a million other advantages and disadvantages. This is sort of like asking: Why has skin evolved to be so soft and easy to cut, resulting in blood leaking out of the body? Wouldn't any animal with cut skin likely bleed to death and die in the wild?"
] |
[
"Simply put: we didn't evolve a way to do it. Some tissues are just special and our body doesn't have the necessary genetic code to replace them. Considering that for most of human history something like losing an arm was pretty fatal most the time it makes sense we can't regrow arms - there's no point in being able to if the vast majority of the time you'll bleed out or get an infection anyway. Surviving amputations is a fairly recent medical breakthrough overall."

How music is stored on CD's and then played back

[
"like ur a pretty smart 5yo: a recording machine listens to the music as it's being played, and turns it into numbers. it records thousands of different numbers every second to represent the changing volume of the music. these numbers are written down very small on a CD, in a spiral that goes around and around and from the inside of the CD near the hole to the outside edge. your CD player reads the numbers that are written on the disk, and using a speaker it pushes air around to those places at those times. the speaker makes a similar vibration like the original sound, and the vibrating air reaches your ear and sounds like music!"

Why can't current be defined as co-directional with the flow of electrons?
|
[
"Because current is the flow of charge, not electrons. The particles that allow for the flow of charge are called \"charge carriers\" and electrons happen to have a negative charge, so current flows in the opposite direction of electrons. Electrons aren't the only charge carriers. In semiconductors for example, you have both free electrons and places for electrons to go (called \"holes\") which can act as charge carriers. In your body, positively charged potassium ions act as charge carriers. Essentially electric current is defined without caring about what carries the charge, just the direction the charge moves."
] |
[
"You can have an electric field without any electrons at all. Electric field dictates the magnitude and direction of Coulombic force in a region of space as F = qE. If you stick a bunch of free electrons in an electric field, they will flow opposite the direction of the field."

Why can the aging process of alcoholic beverages not be artificially sped up or completely skipped?
|
[
"Often alcoholic beverages are aged in wooden barrels. During the aging, the beverage is infused with flavour from the wood of the barrel. While theoretically it would be possible to artificially add those flavours, it is difficult to know exactly what and how much to add since those flavours are very subtle and depend on a lot of things, including the wood used, the specific beverage and the time it is aged for. There is also little incentive to do so, as often aged beverages are enthusiast products, and enthusiasts usually aren't very appreciative of artificial flavours. The long aged products are a status symbol as well, and skipping the aging process would diminish their value and prestige as a status symbol."

How does the heart send more blood to one area when needed if all the veins are one "circle" system?
|
[
"The heart pumps faster to send blood faster during these times, but the vessels dilating and contracting are what determines where the \"more\" blood goes (really just a higher volume to one area and lower volumes everywhere else, not actually more). This is done by nerve signals from the area that needs it to the brain telling the brain (autonomic nervous system) \"hey we need more blood here stat!\" Heart pumps faster, vessels dilate in the area you need the blood and contract elsewhere. Voila! More blood."
] |
[
"Blood doesn't rush around your body in one big tube. What happens is the blood vessels split and become thinner and thinner. Think of a fan where the bottom is the main artery which splits into finer tubes called capillaries. This splitting happens all through your skin, so there are millions of very fine capillaries covering your body. Once the cells have taken the oxygen from the blood through the walls of the capillaries and given up the waste products back into the blood, then the capillaries then all join back up again into veins and travels back to the heart. So, when you chop off an arm some of the fine capillaries are lost but the vast majority are still there. The amount of blood and the pressure of the blood get messed up for a while, but the circuit still exists."

How did the first person with HIV/AIDS become infected?
|
[
"This is impossible to accurately answer because obviously nobody can be 100% certain. But the most likely vector would be from somebody coming into contact with infected monkey blood, which then entered that person's bloodstream, presumably through a pre-existing cut or abrasion. Many species of monkeys and apes are common food animals in parts of Africa, so it's highly likely that people would be regularly encountering monkey blood. Although HIV doesn't live for long once its host dies, if a freshly-slaughtered monkey bled onto a human being, that human could then become infected with the virus."

Around a 1/6 of that stock is reserves and then rotated to other libraries so it appears new to the customers of that branch. Encyclopaedias are really common actually, especially older ones we have around 10 full sets of the most common things like Britannica and Oxford. Any book dealer will most likely have a few sets kicking around if you are short. In the UK the British Library has virtually every book and periodical ever published, I assume the Library of Congress is the same in US and we can get copies of stuff from them.

Why is creating a male contraceptive pill so challenging?

"I literally heard about this on the radio yesterday so i may be able to help. A male one is in development currently in Australia (I think) and has had effective trials on mice in labs showing that it is able to be effective with no major (maybe any) side effects. The difficulty is that a male pill has to stop every single sperm, which males produce millions of, from entering the female's egg, if one gets through, the pill can be redundant, however, a female contraceptive needs to simply stop one egg. So its much easier to stop one egg then millions of sperm through a pill, which is why the female pill has been around since the 60s while the male one is still being developed. Additionally, there is a lot of negative feedback from consumers on it currently."

NASA's new EM Drive, why is it significant, and does it break the laws of physics?

The key thing about the EM drive there is no measurable stuff coming out of it. Does it break the laws of physics? No. If it broke the laws of physics it wouldn't work.

How exactly does an acne cream like 'Neutrogena On the Spot' work to help heal and diminish pimples and what does it really do?
|
[
"There are two types of medications used in these. Benzoyl peroxide. This helps dry out junk clogging the pore so that the environment inside the pore is less awesome for bacteria because it lets in oxygen. BP also dries up everything not pore, making your face a wasteland of dead skin chunks and redness that *may for some people* make skin more prone to further infection. Go with lowest %. Salicylic acid. Breaks down the bonds that hold gunk over the pores, making the outer 'shell' of the pimple separate so oxygen can get in and make the pore less awesome for bacteria. Helps reduce fluid and swelling - so the size of the pimple may go down. A dab on the spot overnight works quite well. 2% is pretty good for a face/body wash that many like for preventing breakouts without drying out their skin. I use other stuff because these two (and Rx exfoliants) have wrecked the acid mantle of my skin in the past. The acid mantle is the true hero. Exfoliate and lubricate. Oil is not the enemy. _URL_0_"
] |
[
"Many things could be going on. You may have been allergic to an ingredient in common facial cleansers (like salicylic acid). More likely is that these products were drying out your face too much, so you skin responded by producing too much sebum (oil), which in turn clogged you pores. I have battled terrible acne all my life. I have been on Accutane four times -- the drug worked wonders while I was taking it, but the acne returned when my course was complete. Now, I use a product line from La Roche Posay called \"Effaclar.\" It's pretty much just benzoyl peroxide, and it's amazing."

Sometimes it wont be a cash only deal, often it will be cash plus stock. In which case, the guy selling gets the cash and also gets signed over a load of shares which they can do with as they please. Either way, someone somewhere will be buying big houses and speedboats."

If I practice normal motor skills with my non-dominant hand, will it ever be as good as my dominant is naturally?

"It depends a bit. A lot of us lefties are pretty much forced to use our right hand in various situations (ever laid eyes on a pair of seamstress scissors?

I write with my left hand, use scissors with my left hand but prefer to hold a screwdriver in my right hand. Probably because the tool pockets on my first pair of workshop pants were all on the right side and it made more sense to use the hand I already held the tool in. Ironically, I prefer I hold my Hitachi power tools in my left hand. This suggests that all it takes is to teach yourself well enough with the non-dominant hand is a lot of practice. In reality, you have a lot of use for it if you work in a mechanical field, so if you really need it often you probably already have *some* of this ability honed to usefulness."

Why is it acceptable for smokers to take additional breaks at work?
|
[
"It isnt! I found out that as a non-smoker, if you start hanging out with the smokers during their \"breaks\", it will cast a negative light on their excessive breaks and bring about enforcement of established times for said breaks. It should be just as acceptable for a non-smoker to take 10 minute breaks every hour as it is for a smoker. If management has a problem with you as a non-smoker taking these breaks, you have a case for discrimination. A person's habit should not make them above company or workplace policy."
] |
[
"Super short answer: Perception. Smoking is seen as a need (addiction) so it's permitted. However, going outside for \"fresh air\" is seen as lazy. As for the bathroom comment? Your bowels will be finished when they are finished. I have always looked questionably at people who can poop faster than I can pee."

"Inside the tiny bag is ~99.99% gravel or sand, the other 0.01% is a chemical called silver fulminate. It's a highly unstable chemical that ignites under any sort of friction ( by dropping, squeezing, or stepping on it). When the chemical ignites it creates a shockwave that travels faster than the speed of sound and that's where the \"snap\" sound comes from (kind of like how a whip makes its noise). This shockwave is extremely weak and that's why you can pop one in your hand and it wont hurt."

If two perfect singers sing the same song and can sing the same octaves and notes, how do those two singing voices still sound different?
|
[
"Every person, and every instrument, plays each note slightly differently. If you take A over middle C, it will always be 440 Hz no matter whether you sing it, play it on a piano, play it on a saxophone, etc. But just because the note itself is 440 Hz doesn't mean that all of those 440 Hz notes sound the same. Each instrument is playing a 440 Hz fundamental frequency, but it's also playing a bunch of other significant frequencies that are multiples or fractions of the fundamental frequency. The overall sound produced by the fundamental frequency, and all of the other frequencies, is distinct for the different instruments - and that's what we call the \"timbre.\""
] |
[
"Pitch (the musical note) is unaffected while the color of the sound is affected. Imagine playing the same note on a violin in a closet vs playing it in a concert hall. The same note will have a different quality of sound based on the acoustics but the pitch will be the same. So we can match pitch. Likewise we can imitate sounds and sound qualities but if you want to do a perfect impression you’ll probably be checking your recordings and training against those."

Industry lobbying, for one, because spices (as the example at hand) may be secret, or may change frequently, or are otherwise just too difficult to keep updated. They also make up a very small part of the product, not enough to affect anyone, and so there's really no point in listing them."

How does a computer processor "turbo-boost"?
|
[
"A computer processor (CPU) has an internal clock. It \"ticks\" so many times per second. A CPU running at 3.2 Ghz ticks 3.2 billion times per second. This is **very** roughly how many calculations it can make per second. You can make the CPU run faster by turning up the clock so that it ticks more times per second. The downside to this is that it creates more heat. Modern CPUs very carefully monitor how much heat is being put out. If the CPU is currently fairly cool and it has a lot of work to do, it can temporarily boost the clock speed. That's the turbo boost. If it gets too hot it will slow back down so as not to damage itself."

Why is it so easy to notice bad acting? What are good actors doing that makes them seem more natural? Is there a scientific explanation for how we tell the difference?
|
[
"It's seems pretty simple really. When we watch a film or TV programme we subconsciously compare how an actor is acting to how we see people act in the real world, or even how other actors act in the same scenario. If the way they act isn't congruent to our pre-concieved notions of how they should act, then we regard the way they act as wrong, and regard the actor as a bad actor."
] |
[
"Watch \"what's eating Gilbert Grape\". Leonardo Dicaprio played the role of a young autistic boy, and afterwards many people were surprised that he was in fact not autistic. A good actor will play a role in his own way, a great actor can basically discard his own feelings and replace them with that of his character's. (that's not to say great actors have no opinions, but as soon as the camera is on they stick to their role) Another favorite example of mine is Rowan Atkinson. The man is crazy intelligent but somehow manages to act the fool, and makes us actually believe that he is one."

How does laundering money through expenses work?
|
[
"As a general rule, you can't. Laundering money requires that you inflate _revenues_ so that you can pretend your dirty money was earned through legitimate sources, thus \"washing\" it. Now, that said, you can't just inflate revenues forever. If you run a business and suddenly double revenue without _any_ increase in expenses, it is going to look very suspect to the IRS. You need to also increase expenses to make it look like you are spending the cash required to generate the revenue you are claiming. It is also possible that those fraudulent expenses are how they are getting the laundered money out of the business. If the cartel boss _owns_ the business that is getting payments for the fraudulent expenses, you are able to send him the laundered profits from the business and have it look like a legitimate business transaction."

Why does my nose run when I eat food with cayenne or similar pepper spices?
|
[
"Chili peppers, used in spicy foods, contain capsaicin. Other spicy foods, such as horseradish and wasabi, contain allyl isothiocyanate. Both capsaicin and allyl isothiocyanate stimulate a reaction in your nervous system, causing your nose to run. Your nose runs when eating spicy foods because both capsaicin and allyl isothiocyanate irritate the mucous membranes in your nose, thus producing mucus in your nasal passages. This is a defense mechanism your body has to keep out unwanted particles, such as dust. Thus, the more irritated your mucous membranes become, the more your nose will continue to run."

Why does ice stick to your fingers when you're holding it?
|
[
"Basically, the ice is so cold that it can freeze the thin layer of moisture on your hands. As the ice warms up, then it doesn't happen anymore. Your skin has a small bit of moisture on it. Fresh ice is usually below the freezing point meaning it has some \"room\" to absorb more energy before it becomes water. So, the ice is freezing that thin layer of moisture on your skin causing it to stick. This is also why the ice sticks worse if you have just recently washed your hands as there is more moisture available. How much it sticks also depends on the temperature of the freezer that the ice is in."

Colleges are 4 year institutions that offer up to Bachelor's degrees, as well as trade certificates and Associates degrees. They're typically state funded or private institutions. These are smaller institutions which offer a smaller number of degrees, and are generally specialized. An art college, or a STEM college, for example. Universities are 8 year institutions that offer all the way up to Doctorate degrees. These are either funded by the state or privately. Universities have many colleges within them, and can offer a wide variety of degrees. Think about places like Harvard, that have a Law college, a Medical college, a Business college, a Divinity college, etc, etc."

The university is probably going g to be larger and have a wider variety of subjects to study while the engineering school will be more focused.

"We do, but they have to be screwed in to your jawbone with titanium screws. Natural teeth are glued in place by a layer around the base of the tooth called the periodontal ligament. It acts as a cushion and can heal itself so it doesn't wear out. Tooth implants have no shock absorber or have shock absorbers which eventually wear out. The screws can also work loose... People get implants anyway but it's a last-ditch thing and expensive. You're arguably better off living with dentures. Back when I wanted to do something with my life I was going to invent a bioengineered lab-grown periodontal ligament to solve this exact problem so people could have tooth implants with cushioning but then I went crazy and wound up working menial jobs and commenting on Reddit for the rest of my life."

Why do senators and representatives rarely represent the state that they are born in?
|
[
"Americans tend to move quite a bit. This puts us in the position of being able to choose where we want to run for office from. A politician may not have views that align exactly with their \"home\" state, and make a strategic determination to move to a location where they have better odds of winning."

"In theory your Member of Congress/Senator should be protecting the rights and looking out for the welfare of all members of their constituency not just the voters. You have representation just not by a guy you voted in. In ye olden times there was no one who's job it was to consider the 13 Colonies opinions in British parliament."

Why do balloons stop floating after a while, even though they still have helium?
|
[
"Yes, the remaining helium still provides buoyancy, but there comes a tipping point where that buoyancy isn't enough any more to carry the weight of the balloon's casing."
] |
[
"Those things have holes in them for the air to escape. So they have to replace the air that is lost. Why are there holes? Think of a balloon, if you slam a balloon against the wall (analogy for kids jumping on castle) the balloon will burst. But if the balloon is not tied, when you slam it the air will escape and the balloon will be fine. Hope that makes it clear"

How was it possible for us to view the moon landing when the astronauts hadn't returned to Earth yet? (those were the days of "film at 11")
|
[
"For Apollo 11 it was sent by radio signal back to Earth which was picked up by receivers in Australia and then broadcast worldwide. A camera was attached to the lander to film it."
] |
[
"We do have pictures of the moon landing sites taken from space. _URL_0_ Why do we not have more detailed pictures? Because the moon is very faaaar away from the camera. But a part of the conspiracy theory is that it was just Apollo 11 that was didn't go to the moon, the rest did, which means that they could have planted all of the landing site stuff there for us to see now. NASA only faked A11 to beat the Russians, after they actually had to go there to plant the evidence."
