Why do we enjoy the feeling of being scared?
|
It gives you an adrenaline rush. Adrenaline can be VERY addictive. That's why adrenaline junkies are sometimes willing to put their life in danger just to get that rush.

How much do Finance, Economics, and Accountacy majors know about each other's fields?
|
One can argue that accounting records economic transactions to build financial statements that are then used in finance to establish the worth of a business which drives further economic transactions . As a result of the relationships between the fields, many undergraduate and graduate business programs encourage interdisciplinary exposure. Specifically, many business programs require students to take the basic introductory classes in each related field and facilitate multiple degrees . As a result students often become more versed in each field both to better understand their own field and to become more marketable. While an accountant may only know the basics of each field they will not be experts unless they decide to pursue it. TL;DR the fields are related and in order to produce more marketable students academia encourages interdisciplinary degrees. As a result members of each field tend to have, at a minimum, a cursory/introductory knowledge of the other fields. Source: Majored in finance, accounting and economics. Edit: source and grammar', "Finance and accounting have significant practical overlap; they're both business prep, and each is supposed to take at least the introductory classes in the other, so that financiers can make sense of accounting records, and accountants know something about the stuff they're making accounts for. Economics is effectively unrelated . An undergraduate economics project is much more likely to use a dataset provided by, for instance, the BEA or BLS than to pore over a particular company's quarterly report.

Why is the night sky different colors in different parts of the world?
|
Light pollution will be part of the issue, but it usually causes a glow. The difference of color seen in the sky is usually due to the dust in the atmosphere. In farming areas the sunset will appear different than the sunrise. This is due to the fact that working the land turns up a good deal of dust into the atmosphere. It is most visible around sunrise and sunset as the sunlight is passing through more atmosphere at this angle than at noon. I'm not particularly familiar with the areas that you mentioned and what businesses might be stirring up stuff in the atmosphere or otherwise introducing particulate/chemicals to the sky over you. After typing that first part I also thought of the fact that northern lights could be influencing the color as well. Particulate and light pollution could be reflecting colors of the Aurora. If you are unfamiliar with the idea, it is basically when the magnetic waves cause a colored light shimmer near the poles due to the higher density of magnetic waves at the poles. These waves can be imagined as loops that go through the earth from North pole to South pole and then loop out and around to the other pole. Think of these loops forming a shape like a small Donut where the line between poles is directly through the hole. I apologize for any lacking clarity as I'm still working on my first cup of coffee.

Why are male beauty pageants significantly less famous than women's such as Miss Universe?
|
Across the human species, men are more visual in their attraction to mates than women are. Staring at a bunch of female hotties is something that appeals more strongly to a bunch of males than the other way aroundThe cultural norm has been that women attract mates with their appearance, and men attract mates with they abilities. We should note that beauty pageants have been in a serious decline in recent decades. Miss America used to be a must-see event, people would talk about it like they would the Academy Awards and the media would cover her throughout the year like she was royalty. These days it barely makes the news unless there is some controversyWarning: possible bro-science. Due to testosterone, men are more attracted to visuals. Women are attracted to emotions. Pageants are primarily a visual display, and men rather prefer to see women.

Why do burps sometimes get stuck in our throats?
|
Haha it's nothing too serious. If you've got chest pains, or finding it hard to breathe sometimes It might be due to achalasia cardia. Just go to your local pharmacy and tell them your symptoms. I can't remember the name of the pill, but when I do remember, I'll tell you.Your Esophagus has 4 constrictions Maybe these constrictions have something to do with that 😂

|
How do they grow seedless oranges and such without a seed?
|
For oranges, by not pollinating the flowers. The plant is otherwise normal. This isn't always true though, different seedless fruits are seedless for different reasons. Seedless watermelons are hybrids of two other watermelon species that, when combined, cannot produce functional seeds. These plants must be rehybridized with every planting since they're sterile. Seedless bananas are all clones of a single mutant plant, grown from cuttings of other clones.

What does Adobe Air do on my mobile phone?
|
I'm a developer who uses AIR, its a runtime to run certain apps in, like Java is. These days, we don't need users to install the AIR app separately, we can package the runtime in with our apps, but some older apps might still need the separate app that you have.

What is that watery stuff on top of the sour cream when I open the jar?
|
Sour cream is related to cheese . The protein infused water that sometimes separates out from the solids is called whey. The solids are called the curd. As an aside; Little Miss Muffet was essentially eating cottage cheese.

The difference between SSRI and SNRI
|
SNRIs act upon, and increase, the levels of two neurotransmitters in the brain known to play an important part in mood: serotonin, and norepinephrine. These can be contrasted with the more widely-used selective serotonin reuptake inhibitors which act upon serotonin alone. Norepinephrine along with epinephrine, norepinephrine also underlies the fight-or-flight response, directly increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow to skeletal muscle. It increases the brain's oxygen supply.Norepinephrine can also suppress neuroinflammation

How much does internet mobile data actually cost a phone company?/Why is it so expensive compared to home internet plans?
|
It costs barely anything, on the order of fractions of a cent per MB. It costs so much because people will pay that much for it because having internet literally anywhere is really convenient. You're also covering operational costs , startup costs , and R & D required to make it all happen and get better every year.At low-usage times it's relatively inexpensive. At high-usage times, it becomes less an issue of "we paid money for this" and more an issue of "everyone wants it, so we charge the price the market will bear for a scarce commodity." It's a bit like selling lemonaid on the side of the street. The ingredients are inexpensive. But on a hot summer's day when everyone wants lemonaid, and you only have so much of it, you're going to maximize your profit. So, your real question is "why is mobile data scarcer than home internet"? Well, there's a lot of complicated science in there, but mostly it's because there actually is a maximum amount of data which can be transmitted on a given spectrum of electromagnetic radiation at a time. That limit can only be increased by better technology, whereas more data across land-lines is mostly an issue of laying new lines.Almost nothing. Like most stuff today, the markup is insane. Why? Because people still pay for it. It's the same reason why football and hockey jerseys are nearly two hundred dollars and they are still not the best quality.

Why is Carbon Tetrachloride (CCl4) not flammable? Does it have something to do with its geometry?
|
Fire is rapid oxidation. Burning gasoline takes things like C8H18 and turns it to 8 + 9 * with the help of plenty of our friend oxygen. When you get into the chemistry of it though, oxidization is not just adding oxygen to a molecule, it's actually pulling electrons away from whatever gets oxidized. The reason this happens is because certain atoms, like oxygen, really like electrons more than others like carbon. So while the carbon bonds to the oxygen by *sharing* its electrons, the oxygen is actually pretty greedy and holds the electrons closer. This in turn makes the bonds stronger. Because the oxygen pulls the electrons away from the carbon, the oxygen is more negative and the carbon is more positive, so they have that opposites-attract thing going. Thing is, chlorine and other halogens also really like electrons, too. The carbon in CCl4 is about as oxidized as it can get - you could oxidize it more, but not with something like a lighter or stove. * and other things with incomplete burning, like soot and carbon monoxide", 'The carbon is already tightly bound to four chlorines. For it to burn there would have to be an energetic advantage to breaking four chlorine bonds and making two double oxygen bonds. Someone with a better memory than me will probably be along in a bit with numbers, but IIRC the chlorine bonds are stronger.

Why my medicine costs 14k for every dose. How is it even possible for a chemical to cost that much?
|
You aren't paying for the actual chemical, you are paying for all the research that led to the creation of that medicine. It may take a company millions or billions of dollars to find, test, and build manufacturing to develop a new drug, and then it may cost nearly nothing to manufacture each dose.

Why is the locomotion of a camel so much different than that of a horse?
|
They move in a similar way to a giraffe, the gait comes from having relatively long legs compared to the length of the body of the camel. By moving both left legs then both right they reduce the chance of the back legs hitting the front legs, avoiding tripping. A horse doesn't have this problem as they have a longer body in relation to their legs.In addition to what /u/thedeicider said, when a camel runs it always has two feet on the ground at the same time while when a horse gallops it often [ends up with only one foot on the ground at a time].

Why did the cost of US college tuition skyrocket?
|
Universities realized that people were always getting approved for their federal student loans, so they kept raising tuition knowing that the students will be able to pay their crazy prices.Supply vs Demand. Education is trumpeted as the only way to make a decent living. This coupled with the near limitless access to funds through programs like student loans increases demand through the roof. Supply on the other hand has stayed the same. This causes the price to increase to an equilibrium. Unfortunately, because of the fact that the ability for people to pay isn't actually limited the price just continues to rise.
|
If I have 1000 dollars in a stock and the stock goes to zero, what happens to my money?
|
Stock represents your share in ownership of a company. When you buy stock, the company gets the money. If the value drops to 0 then that means the company is being appraised by the market as worthless. They may have your money somewhere or they may have spent it. You own a tiny sliver of the company though, and if the value of the stock goes up then you'll be able to sell your stock based on that value. People who own enough stock in a company get to make decisions about it, and even if they don't, companies often worry about "shareholders" and their interests since these people indirectly help fund the company, and through their buy/sell behavior, influence the value of company shares on the market.

How does anti dandruff shampoo work? And are the branded ones actually better than the other ones?
|
Long term dandruff sufferer here! Dandruff is caused by a [yeast infection] eating your sebum . By doing so they irritate your skin, giving you dandruff. So proper anti-dandruff shampoo contains anti-fungals. Most anti-dandruff shampoos contain zinc. For some people this is effective, but generally doesn't work for anything more serious than average. More recently, there's also shampoos containing [selenium sulfide]. This may work better. But it never "cures" you; you will have to keep using in perpeteum. A doctor may prescribe you a shampoo containing [ketoconazole]. This is a pretty strong anti-fungal, but unfortunately you can't use it for any long period of time because it is quite damaging to your skin.Some dandruff is caused by dermatitis/psoriasis and sometimes the only thing that works is a combination of cortisone liquid and avoiding the things that make you as an individual flair. In my own case, carbohydrates make it flair and I have to not eat any carbs and it sucks. In the case of dermatitis it turns out it isn't just a cosmetic and discomfort problem. When your skin is hyper revved up, over-producing new skin layers, it actually uses a lot of energy and can make you more tired than you need to be.

Why are most of the foods that taste good bad for you?

You're just viewing it from your perspective. To me, junk food is good but I'd rather eat properly prepared broccoli. Try accustoming yourself to different foods and healthier foods and you'll see that junk food does not always have the better taste.

Spotlight quote: "If it takes a village to raise a child, it takes a village to abuse them."
|
It takes a village to raise a child is a common proverb which means that a child isn't just raised by their family, they're raised by the joint efforts of their community - their family, neighbours, school, friends, etc. "It takes a village to abuse them" means that in the case of child abuse, not only the actual perpetrators are to blame, but also the entire community which turns a blind eye to the abuse and enables it to continue.

Why do fashion/clothing models always look pissed off?
|
If you notice, many catalog models are smiling and happy - they're trying to get you to buy something. The Victoria's Secret models also smile during their show. But high fashion models are often told not to smile because either it is distracting from the clothes or doesn't meet the "theme" I believe the blank looks on their faces are put there as to not to take away from the fashion they wear. They are just a blank canvas, the artist then puts the art on themI used to work in an advertising agency and I casted plenty of models for different commercials. When they come for casting, I'm supposed to take a couple photographs of each of them. Then I learnt there were a lot of model faces: Smile The "High Fashion" pose And from there there were countless permuations to how they could look. It depends on what sort of campaign and \'look\' you are going after. Someone else in this thread has answered that some models are always smiling. It depends on what suits your brandIts probably because they suck in their cheeks or clench their jaws to make their face look more defined if you do it in a mirror youll know what im talking about', "In regards to your screenshot: those are their blank looks. Some people have naturally frowny faces when they don't make an effort to smile.

What motivated individuals in the North to serve in the Union Army during the Civil War?
|
Many were drafted, some believed in the union. A great book on this is "Free Soil, Free Labor, Free Men" by Eric Foner the very basic gist is that despite what some modern people assume, Northerners and their soldiers were generally not abolitionists, they were often racist to varying degrees and weren't particularly fighting to liberate black people. Instead, there was an important idea of free labor, as contrasted against slave labor. The idea was that everyone had the right to the fruits of their labor, and that slave labor devalued free labor how could a free carpenter compete with the wages of a slave, after all? And not just monetarily devalued, it made work seem like something that was done by slaves who were forced to it wasn't honorable to work for a wage in a slave society, the only respectable thing was owning slaves, perversely. Northern working and middle class people therefor could hate slavery not because they sympathized with black people, but because they didn't want to compete with slave labor. This is why the issue of slavery in the territories/new states was such a massive deal in the pre-Civil War era, northerners felt like if a new state was open to slavery then they had few prospects there as wealthy slaveowners would move in and create a slave economy.

Why are the movement of people in spacemovies so slow, if there is no resistance? (Example: When they climb up stairs)
|
Have you ever been working in a tight space, with a low ceiling, crouched down, and then, without thinking, you stood up and banged your head? If you're not careful, that happens *every time* in space. Imagine pushing off from one end of a tube with about the same amount of force as, on earth, you'd use to get up on your tip-toes. When you reached the other end, your impact would be like walking, normal-speed, into a door. It hurts and you can break things. People in space move their bodies and their equipment slowly on purpose, because otherwise they'd go crashing into the walls and end up covered in bruises. ", 'The suits are not that flexible and are pressurized, any kind of movement with a spacesuit is difficult like trying to move your arm through treacle.Because the gravity is so low, any fast movement, can send them shooting off in a direction they don't want to go. Much like the videos of the astronauts on the Moon. Their movements are slow and deliberate, to compensate the low gravity. Most movies copy that.

How exactly do people avoid taxes using shell companies?
|
Let's say you own a pretty profitable business in the US but you're tired of paying taxes. First, you make a shell company where there are lax regulations and low taxes. Then you transfer the assets that your US company has to the shell company, in name at least. You continue to use those assets in the US to make money and do business, but all the money technically belongs to your shell company. Since your shell company is outside of the US, it doesn't pay US taxes. The tricky part is being able to use assets outside of the US to do business in the US without having to keep the money in the US. There are different ways to get around this. For example, a tech company can transfer all of its patents to its shell company and then the US company can lease them back under terms where money made from their sale belongs to the shell company.

Why can some people eat lots of food, do no exercise but remain thin whilst others struggle to lose weight by eating less and working out?
|
This is a big question. The general answer is that each person has a weight that his body considers as 'ideal'. They will eat, or not eat, enough food to maintain that weight. How that weight gets set is, at the moment, unknown. A thin person will eat enough to maintain their size. They might go and pig out at a party, but might just forget to eat lunch the day after. Another person, who is heavy set and trying to keep their weight below that annoying 'ideal' figure, will avoid eating a lot at the party, but ends up picking at the snacks and having a hearty meal the next day, because they are 'starving'. Their metabolism considers them underweight, and wants to make up the difference. This is all very annoying for those who are trying to loose weight.

How do url shorteners work?
|
You tell the shortening service a URL, it stores that URL in its database and generates a short code. When somebody tries to go to _URL_0_ it looks up the full URL from its database and redirects the browser. Depending on the service the short URL might be temporary unless the person who requested it pays to keep it up. Similarly, most services will let you pay to have a URL with text you choose instead of a random code.

Why are genetic disorders like trisomy 21 much more common than say, trisomy 19?
|
Most trisomies and other severe genetic defects are incompatible with life. The embryo never even reaches the fetus stage. It dies and is expelled in many cases even without the mother knowing she is pregnant. The reason Down syndrome is more common than many others is because Down syndrome embryos can still develop into children.Chromosome 21 is the smallest and most insignificant of the chromosomes. Trisomies do have a more-or-less equal chance of occurring on any chromosome. However, with the larger chromosomes like #1 or #3 or whatever, the issues caused by the trisomy are so severe that embryonic development cannot continue. The pregnancy ends in miscarriage. The reason trisomy 21 is so much more common in living people is that it's the one that the embryo/fetus has the best chance of surviving.

How can someone have negative karma for every comment yet still have a positive karma score?
|
Reddit employs algorithms that try to prevent vote brigading and mass downvoting. For example if you clicked on a user's page and started downvoting every comment, reddit will probably ignore those downvotes when calculating the user's total karma. In this case, the thread was linked from /r/bestof, which caused a massive influx of redditors to view this threads. Most of the downvotes probably come from there. Reddit probably has an algorithm that prevents these downvotes from being counted in the total.

The difference between nerves and neurons.
|
Neurons are the cells that can receive and transmit action potential, they can work by chemical or electrical stimulation and are mostly located in your central nervous system so brain hemisphere, brain stem, spinal chord and cerebellum . Your neurons transmit information thought their axon and basically a nerve is a bunch of axone condensed together and that can transmit information from the central nervous system to your body peripherical region such as muscleAside from expected adaptations the nomenclature is used to separete those from central nervous system from those of the peripheral
|
The difference between a programming script and "normal" programming?
|
There are two types of programming languages, compiled and interpreted. In the first case you the programmer write your code, and then you invoke a compilation step that covers these vaguely English looking statements into machine code that the computer operating system can run directly. For example, on Windows you might write in the C++ language and compile into an exe program. In the second case your code is passed to an interpreter program that runs the commands that you specify. The instructions are called a script, hence scripting language. The interpreter essentially converts your code into operating system instructions on the fly, eg "rename this file". Flame wars have been fought over which approach is better. Generally interpreters are great for rapid development and prototype work but not considered fast enough for complex programs. Compiled programs are harder to write but can do anything you can set your mind to. There is blurring here: some languages try to compile your script to make the second and subsequent runs faster, for example. And some scripting languages are insanely, ridiculously powerful. Python is a good example- When you are scripting, you are giving a series of instructions for another program to carry out.- When you are programming, you are giving a series of instructions for the hardware to carry out.

How does a vending machine know how much money you put into it?
|
i looked this up a while ago, and _URL_0_ might not be the most reliable source, but i think they just have very specific equipment. a machine and computer reads the dollar bills and is programmed to "look" for certain marks on different bills to distinguish them. for coins, it has another system that can tell what material and what thickness each coin is. There might be simpler vending machines out there. **tl;dr** the vending machine knows how to "read" the money and "feel" coins.
|
Why do bullets have curved tops rather than sharp, pointy tops?
|
Bullets with sharp points are meant for maximum speed. The power of a bullet comes from momentum, which is a product of weight and speed. A high powered rifle round doesn't weigh much, but goes *really* fast. A blunt bullet is designed for closer range. The blunt tip will have *less* ability to cut through the target, so it will impart all of the energy in its momentum into the target. More energy = more damage. Hollow points maximize that effect by mushrooming on impact and imparting all of their energy into the target.

Horoscopes, and how they're written.
|
Total BS. They're vague enough that they can apply to totally different types of people, but they're specific enough that when people read them, they think "WOW THAT\'S ABOUT ME!"', "They don't try to make it up - and I'm not arguing for the scientific validity here, but according to their own system, here is how horoscopes actually work: 1. When you are born, the stars are in a certain position at the exact moment of your birth. You can go to a site like the German website Astrodienst, and it will calculate this out for you, and tell you which planets are in which houses and whatnot. Really experienced and math-savvy astrologers can actually calculate this out using math and tables, but there's no need for this now, unless you're an astrological Martha Stewart and you want to do it yourself. 2. The stars are in a different position now, obviously. If an astrologer makes a chart for the present moment, he or she can then calculate how the planets have moved since the year you were born, and whether the position of any one of those planets, say in Ajdiv's example, the place where Jupiter is today makes an angle to Neptune, as it is placed in your chart. Squares - 90 degree angles, are usually bad, and are thought of as causing some sort of negative effect. Trines or sextiles - 30 degrees and 120 degrees I think, but don't quote me - they are more positive. 3. Since obviously it is impossible to make individual star charts and publish them in newspapers for every person in town, newspaper astrology uses a watered down version of this. They compare the position of the present planets simply to fixed sun sign positions, rather than taking entire charts into account.

When mixing liquids of different temperatures, what will the resulting temperature be?

You're right - it does end up at the exact average. Things get more complicated if there's liquids with different heat capacities involved, such as saline and plain water. Phase changes would also complicate matters - if you went from ice to liquid, for example. There's a tutorial [here].

Why is Windows Vista so hated?
|
Vista's system requirements were much higher than XP's, and it dropped compatibility for a lot of software including drivers. For some people this meant that Vista ran slowly and either didn't support their hardware/software or crashed trying. There were a lot of other changes made from XP to Vista, both in the interface and under the hood; and people don't usually like change. Vista to 7 on the other hand had relatively little change, hardware and drivers had also gotten better, and old software was generally replaced.

Why does pain around the finger tips / finger nails seem to hurt so much?
|
Your body doesn't have an even distribution of sensory nerves. Areas like your fingertips or lips have a lot. This allows you to feel temperature, and texture much better with those areas.Fingertips are used to feel our surroundings so they have a ton of nerve endings really close to the surface, as a result even small wounds in the area hurt like hell.

What is Open Source?
|
The literal entomology of the word is derived from the words "source code," which is code that is written before it is run through a program which compiles it, making it into a language the computer understands, but it is virtually impossible to edit the code without the source code. Open source is used to describe a program and means the source code is "open," or released into the public , allowing for the program to be easily customized and modified. Generally open source programs are programs protected by the GPU General Public License, meaning the program is illegal to sell and end users are allowed to use, modify, and distribute the program and source code without repercussions. There is an active community that often modifies the code to make it better. The most well known Open Source project is the Linux project, which is a massive family of open source operating systems, which are widely used, though not as widely among normal consumers, basically all servers and websites run on some sort of Linux operating system. Another example would be the popular mobile operating system, Android.Imagine you have a good waffles recipe. You could keep it in secret and just sell the waffles, without telling anyone what is the secret recipe. People will never know how you make those awesome waffles. They can only but then from you. That's closed source. But you could share your recipe with your friends and family, or post it on the Internet for anyone to see. They can use your recipe as they wish, modifying it, improving it and share them as well. That's open source. If you create some software, you can keep the source code as a secret to keep anyone from modifying it , or you can make the source code public so anyone can see it, modifying it and improving it. Hope it helps.

What is the significance of the fly in Breaking Bad?
|
On one level its about the possibility of contamination. How did the fly get in, what are the impacts of bugs on the cook? On another level its about the Walt losing control. Things that are spiralling out of control and he is desperate to reassert authority and be in control of his life againIn the cold of open of the Fly episode, you can hear Skyler singing a lullaby to Holly. Later on in the episode, Walt is discussing when he should have died, and he said before he left for diapers, the bar and for Jesse's place. In that scene , you can hear Skyler singing the lullaby we heard in that opening. for that explanation in the past ) As for the fly itself, jitterfish explains it the way I understood it, it's about contamination, losing control, etc.

Why do we hiccup? Why does holding your breath stop them?
|
When you have something gross on your hand, like a bug or some rotton food, you flick your hand to get it off. The sudden motion removes the foreign object. The same goes for your diaphragm. A hiccup is your diaphragm moving suddenly to relieve an irritation. The sudden movement moves the lungs and forces air through your vocal cords, making a noise. As for holding you breath, that's never worked for me, I think that's a myth.

Why can't fake blood in movies look more real?
|
It actually can, but it doesn't look as good. People have become used to seeing what they expect blood to look like in movies, and a more realistic version actually looks less real than than the real thing.It depends on what the directors are going for, it can be anywhere from Tarantino stylized blood to gritty realism which is indistinguishable from reality. Only the cheapest of productions are unable to use realistic blood if they want.

Why do people use 4 small tv screens hooked together instead of one big screen on computers?
|
Two reasons 1) Because each screen can display something different. Kind of cool/useful if you need to have multiple streams of information active at the same time. 2) They don't make screens that big for computers. But if you hook up a group of them you can have a bigger screen.You can manage different tasks on each screen. Bigger screens also tend to get exponentially more expensive after a certain size.

How can an AC current be superimposed on a DC current on the same physical line?
|
If you have 50 VDC to begin with, and then make it oscillate between say 43 V and 57 V, that is 10 VAC superimposed on 50 VDC. The reason the numbers don't seem to add up is that AC currents aren't measured peak to peak , but is measured in something called RMS . The peak to peak voltage is the RMS voltage times the square root of two.

I've never heard this. Do you have any source that this is even a thing? My guess is that malnourishment and/or inactivity causes poor circulation and general lethargy, which might feel like depression.
|
Why do patents and copyrights expire? Who/what decides when they do? Is it fair to the inventor/creator and is there a way around it?
|
The idea for patents is this: We, the society protect your invention from copying. In exchange, you make your invention public. So after the patent expires, everything can try to build it or improve it.You can also try to keep it secret, but then people who find out about your invention can build it without restriction.This is quite fair. For copyright, it expires decades after the author's death. So fir him/her it doesn't matter anymore. You could rather ask if it is fair to society that the children and grandchildren can still make lots of money from something they had no part in creating.They expire because things entering the public domain is vital for technological advancement and to prevent permanent monopolies. Patents last for 20 years, giving a temporary monopoly on the product for that period of time allowing the group inventing it to recover research costs and make a decent profit before allowing competition. Copyright lasts for the lifetime of the creator plus 70 years, or 120 years for works created by a corporation/group. This is for similar reason, to give a temporary monopolies on materials to guarantee that you make money off of your works. But it is vital for material to enter into the public domain eventually. For example, Disney would not have been able to make the majority of their movies which are based on fairy tales, folk tales, and cultural legends that have been told for centuries. It is the concept of public domain that allowed those movies to happen. Yes there is one way around copyrights expiring, you lobby law makers to extend the duration of this. Disney has done this at least 5 time, every time Mickey Mouse was about to exit copyright.

Why the Big XII is falling apart
|
Someone can probably provide a better answer as I tend to focus more on the Big East, but I can give you a general idea. Key factor in all of this - money. In general, the Big XII has two television deals - one with Fox Sports that is shared evenly amongst all of the schools, and one with ABC that tends to gravitate more towards the schools that appear more on ABC . The smaller schools want an equal share. Texas, who receives more money from media deals than anyone in the Big 12, is willing to share all revenue evenly, but is not willing to share the $300 million over 20-years from a deal with ESPN to create The Longhorn Network. This unwillingness to share didn't make Texas A & M happy, so they decided to bolt for the SEC. With Texas A & M moving to the SEC, suddenly the Big 12 was left with 9 teams and the schools in the conference got scared that they wouldn't have a home, so they all began to find places to go to be safe. In general, all the Big 12 schools still want to live together in one big house if they can - and maybe bring in a new roommate to live in Texas A & Ms room, and they are trying to now.

Nothing, because you are already holding the burger. Eating doesn't make weight go away or change or anything.

How would the Church of Scientology be able to sue HBO on any grounds in the first place?
|
They can sue all they want, come up with any reason they want, get it into courts and in front of a judge and cause HBO to have to respond to anything they say. They don't have to be right or valid, but if they get sued HBO still has to respond in some legal way.Many times, suing someone isn't about winning in court. It's about causing them financial pain. So, Microsoft could sue you because you have "windows" in your house saying that violates their trademark on the name. Of course that's completely ridiculous but how much can you afford to spend proving it's ridiculous??', "[Wikipedia] has a good summary of the laws that scientology uses to sue people. Basically, you can sue for whatever you want, but even if you don't win, you can still cause indirect damage like the time/money spent on defending yourself from the lawsuit.

other than snakes, why do almost all land vertebrates have 4 limbs?
|
evolution is essentially survival of the fittest not "fit" as in fitness and health so much as it is "fit" as in adapted to the environment they live in. at some point, some creature crawled out of the water and was able to survive on land. over time and generations it had mutations in its offspring that made different versions of it, some of those mutations were helpful to its survival, and those ones lived and had offspring that, even if they didn't have the beneficial mutation themselves, they had the genes for it so their own offspring would possibly have it. the ones that had the mutation were more likely to live because of the mutation, and thus were more likely to survive long enough to breed and pass it on. detrimental mutations on the other hand would make it more difficult for the animal to survive, and thus less likely to live and pass on its genes with the detrimental mutation, so those ones died off. so this newly land dwelling creature has offspring that eventually mutate fins to legs and they survive better that way and they continue mutating and spreading across the land and over millions and millions of years we now have countless variations of the same creature that emerged from the water so long ago most of them are so mutated they can barely be recognized as being related. however, like the 4 limbs, they all share common traits that helped them survive and prosper.

What will happen to the ISS once it's mission ends in 2020 (or 2024 maybe)? Will it just stay up there and continue orbiting?
|
The ISS is in a fairly low orbit at which there are still very small quantities of Earth's atmosphere. This wouldn't normally be an issue except that the ISS is massive, and has massive solar panels which act like a sail, creating measurable drag, slowing it down and causing it to spiral back towards Earth. As a result, they periodically [reboost it to it's target orbit]. If they simply abandoned it, then it would spiral back to Earth. In reality however they would de-orbit it deliberately in order to ensure that it would re-enter and break up over the Pacific or another unpopulated area. That is unlikely to happen in 2020 however as the mission will probably be extended - the current international funding agreements just run until then.

Why does feces and urine smell so bad?
|
So we instinctively avoid it, as it can harm us', "Because it's rotting, partly digested waste . and if it smelt good we'd probably re-eat it. It's actually a good thing that it smells bad.We are asking the question wrong. The question is "Why do they have a smell?" and not "Why do they have a bad smell?" All smells are nearly the same. It's just we who connect them with "good things" or "bad things", thus making it "good" or "bad". Its like a hit on your head. If it comes from a friend, you don't mind it. You might even start liking it. But if you know your mom is hitting you as punishment, you'll start hating it.It's called waste for a reason! It's not necessarily just food coming out. It's also a bunch of byproducts and even toxins that we're getting rid of.

Why do people claim milk is unhealthy when we are all taught that it is healthy?
|
An interesting series of studies on low-fat vs. full-fat dairy. A 46% less occurrence of diabetes in full-fat dairy consumers. Of course, correlation is not causation, but 46%?!!? GeezI believe what you're referring to is the "adult humans are not meant to drink milk" idea. After a quick Google [search], this appears to be true for about 60% of the world's population after they have been weaned from breast milk; the gene for processing lactose breaks down in these people. I have also heard people, usually those who are super into "nutrition tip of the moment" stuff, say that milk is actually bad for *all* adults, rather than just making *some* adults uncomfortable. Personally, I haven't heard anything to support this but maybe there has been some new research suggesting possible health consequences. Edit: a word', "The USDA’s recommendations are based on the fact that milk is a prime source for three important nutrients: calcium, potassium, and vitamin D. However, as beverages go, milk is relatively high in calories. One cup of 2% milk has 138 calories, for instance. Drinking three cups a day adds 366 calories to the diet. Consuming a cup or two of milk or equivalent dairy is fine. But it's also important for people to know that they don’t have to drink milk to be healthy. Source: _URL_1_

How does alcohol in hand sanitizer kill bacterial cells but not our own cells?
|
It absolutely does kill your own cells. If you drank hand sanitizer you would die. It can blind you if you get it in your eyes. Your skin keeps it away from the rest of your cells because that is its job, but it absolutely does kill your cellsIt *does* burn away your own cells. But the outer layer of your skin is already dead, so you don't really notice. Try pouring alcohol over an open cut, though, and you'll feel it burn like hell. That's it "sanitizing" your own cells.It *will* kill your cells. Fortunately for you, most of the cells it comes into contact to are already dead, as that's what the outer layer of your skin is.

Why do we feel inclined to sing when music is present?
|
I think the answer would depend very much on the person. Different people sing for different reasons, and you can also sing for different reasons in various contexts. For example, you said you sang "when driving in the car, for example, or doing the housework". Housework is usually mundane, and driving sometimes can be as well. Perhaps in those situations it relieves boredom. Also, "The\xa0act of singing releases endorphins, the brain's "feel good" chemicals, according to [this source] We may also feel inclined to sing if others are singing. In that situation, I would imagine it adds to the shared experience, and increases your connection to the music and the band and the people around you. According to\xa0[this study] collective singing increases the singers\' feeling of psychological wellbeing. [Certain songs we are more able to\xa0sing along to than others for various reasons.] The specific notes and pitch and tempo of a song can be more easily copied by others than copying dialogue. So I think that would explain why people don't often "talk along" to specific pieces of dialogue. Although having said that if it is a well known phrase, like [\'I drink your milkshake!\ or [\'You talkin\' to me?\ or [\'Frankly my dear, I don't give a damn\ then people will sometimes speak along. tl;dr - because it's fun. EDIT - I posted this on mobile, so I fixed the links after first posting it 😊', "That's an interesting question! I guess it may because you want to join the music you like. A kind of situation that when I heard someone played some music that I have been induced, I would also like to join to play somethings together that we want to communicate through music.Because music is haunting and it makes you sing along even if you have a non melodious voice. Music helps you feel happy from within and lifts up your mood instantly. And it shows how much you love music and your interest to sing along!

Why do commercials sometimes only appear for a split second before being replaced by another one?

You mean on TV, right? The times I've experienced this was because my TV service provider aired their own commercials instead of those the channel had been paid for/those the channel had made. There was a little delay, so some commercials were only shown for a split second.

What is a Single Payer Healthcare System?
|
It is where the is literally one payer for all healthcare bills -- the government. Instead of having dozens of different insurance providers that doctors and hospitals have to deal with, there is a single point of contact for submitting all claims. Sort of like if the government's Medicare for seniors was extended to everybody.You pay the government via taxes. Then, when you go to the hospital, the hospital bills the government instead of you, cause you already paid for your healthcare.

Why can we tell if a bill (currency) is fake or not/
|
Money is like a cake. You have slices of it, and it's delicious. But what's it made out of? Well, there's a tricky question. Eat the cake and find out? You can try. Hell, let's say you do it. You somehow know every single ingredient in the cake. More still, you somehow know the exact measurments. But if you put that all in a bowl, would it make a cake? Well no, there is stirring and preheating and the perfect cook time. Then, getting beyond the basic cooking process, you have butt loads of frosting. And the cake decorator is that guy who can make like, castles out of frosting. Happy baking

How do people perfectly colour previously black and white photos ?
|
It's basically painting a transparent picture on top of the black-and-white, and the B/W image provides much of the shading.In the days before photoshop, you had actual transparent inks with limited tints to choose from, and that's why old hand-colorized photos often look more cartoony. Now, you can pick from a vast range of colors until it more or less matches what you would expect: a white person with fair hair will probably have skin in X color range, unpainted wood furniture is going to be a shade of brown, jeans are almost certainly blue, a military uniform from that era is going to be this particular color, etc.Plus if you have experience with B/W photography you might have a sense for how some colors will translate to film; they often have a particular range of grey due to the characteristics of a given film. So accurate colorizing mostly comes down to digital painting skill and having a sense for how things would look.

The concept of judicial standing in the United States
|
In order to be party to a legal process you have to have a reason to be involved. You can't just assert a right to participate. So for example if you want to sue the NSA for listening to your cell phone you have to prove to a court that the NSA actually listened to your cell phone first. If the NSA refuses to admit that it did such listening, the court may decide you don't have "standing" to bring the suit.Standing can be fairly complicated, but the ELI5 version is that only people who have been harmed can sue the wrongdoer. For example, you can't sue a company for discrimination just because you don't like discrimination. You have to show that their discrimination actually affects you.

the origin of firm handshakes
|
Handshakes came about in the same way that salutes in the military evolved. A thousand years ago people had no means of quick communication, so they were vulnerable to being robbed or attacked on the roads. They couldn't exactly call the police, after all. A hand wave and then a handshake was a polite way to take your dominant hand away from any weapon you had in a way that showed the person you were approaching that you were willing to put yourself at a disadvantage in order to have a polite encounter. The military salute evolved the same way. Officers didn't want to worry about their soldiers stabbing them every time they walked by, so they made them salute. Of course, nobody likes to get an awkward, limp handshake. A strong grip conveys confidence and doesn't feel weird, so it makes a good impression on the person whose hand you are shaking.

How Argentinian currency devalued 15% overnight and the upcoming emerging markets financial crisis.
|
A currency, or a Promissary Note, or "Bill" is essentially a promise by a government to pay you. Currency is a much easier way to make a transaction than bartering. But the currency must have a value. It can be backed by gold , which is why many countries keep gold bricks under lock and key. Or currency can be backed by other, more stable foreign currencies - such as the US Dollar, Euro, Yen, etc. Some countries keep a mix. The key to a stable currency is trust by the public that it holds its value. But some countries print more bills than they have foreign reserves to back it up. This devalues the currency. A Government can announce what the currency trade value is and force banks to trade at that trade rate . But if the public does not believe it, then they can create their own market and trade 12 AR Pesos for 1 US Dollar. Argentine citizens can also cause panics, if they don't trust their government. Even if the government really and truly can back up 8 AR Pesos per 1 US Dollar, if the public doesn't believe it, they can panic and still create their own market trading at 12 AR Pesos for 1 US Dollar.

2 ways: 1) You lose water vapor in your breath as you breathe out during sleep. 2) you body still needs energy when you sleep, it produces this energy by burning sugar, the byproducts of sugar metabolism is CO2 and water. You then breath the CO2. All that Carbon you breath out adds up over the night.See this video: _URL_0_ TL;DW: You do sweat, it isn't dramatic like I you were running, but it's still there. There's also loss of weight that occurs when you convert oxygen to carbon dioxide.

How come when i cook an egg over a campfire it explodes unless i poke a hole in it but hardboiled eggs dont.
|
Direct heat from a campfire is going to heat the inside of the egg much quicker than boiling water . When you hardboil an egg the air inside it slowly expands and escapes through the shell as the egg heats. When you heat an egg over a fire, that air expands quicker than it can escape the shell, so without a hole to act as a vent, it will build up pressure inside and explode.

How and why does taking your pen drive off your computer without "safely removing" it cause harm to the pen drive?
|
You're waiting with your dad at the bus stop. The bus pulls up, opens its doors and lets kids on. Now, it takes a while before all of the kids get on the bus and the doors close. It also takes a while for the kids to sit down so the bus can safely move. When you copy a file and it finishes copying, that's like the kid being on the bus. When you "safely remove" a drive, that's like saying all of the kids have sat downIt can't harm the drive itself, but it can cause some of the data to become corrupt. When you copy data to the device, it doesn't get saved instantly. The OS queues it up to be written out a bit later, when it's convenient to do so. The "remove safely" feature informs the OS that you want it to flush any pending writes to the device, and let you know when it's done fully saving data.If it is modifying a file when you pull it that file could become corrupt. It'll be half-rewritten and when your computer goes over the break it won't understand what's suppose to be there.Reading from and writing to the drive is slow. In order to pretend that it's faster, your computer just stores whatever you're reading/writing in RAM instead of actually writing it to the drive. When you "safely remove", you're telling the computer to actually write. If you yank it out without giving it this chance, then files could get corrupted. You won't actually "hurt" the drive though. This is also why you 've probably gotten away with just yanking it out with no issue--if there aren't any pending writes, there's no harm, but the OS still grumps at you.If you're using Windows and haven't changed the settings, it doesn't matter, the stuff is written your your USB drive ASAP. Don't pull it out if it's flashing though, wait until it's finished what it's doing.

The difference between analog and digital
|
Everything in the world is analog. For computers, we created a digital signal. It isn't truly digital, it is still an analog signal, we just design the electronics to interpret everything to have only 2 states: 1 or 0. This allows us to turn switches on and off and manipulate information in a relatively easy manner. It's also much more versatile to do things this way. Digital is how we refer to everything processed as binary information. Everything else is analog.Analog can have nearly infinite values. Digital can have 2. Think of a lamp with a dimmer switch vs. a lamp with simply an on/off switch.

why are guitars so expensive?
|
It's all in the materials. Some wood is very expensive and some woodworking techniques take a long time to master. That is where the costs come from. The sound they produce is really just a matter of the design and density of the wood. Pine is going to sound very different than oak. I would also say this applies to all instruments. There are violins that sell for millions that sound the same as the one produced in a factory last week. [Here's a great NY Times article about this.] In the article many of the musicians praised the newer violins , but when they were told which was which many of them brought up how the old intruments were still better.sometimes you pay for the brand name sometimes its the craftmanship but mostly its to make a profitlike how two gas stations right across the street have different pricesthey want to make the most money for the same product

Why are some movies not rated?
|
MPAA is a private non governmental entity that rates movies based on their content. Their ratings are nonbinding, but pretty much all movie theaters observe them to appease public desire for decency, and to avoid govt censorship. Most movies that are released in theaters will get rated. They might avoid it if a rating would most likely result in NC-17, which is associated with being overly smutty or dirty, and just short of pornography, and would kill a lot of audience interest. Most movie theaters treat an unrated movie the same as an NC-17 movie anyway. A lot of dvd Versions are marketed as "unrated", which just means they have added content that wasn't included in the theatrical release and therefore never received a rating. For the most part, these would have retained their original rating, but it makes movies, particularly raunchy comedies, seem more extremeThe Motion Picture Association of America , the board that rates movies, is not a government agency that can force you to submit your film to them for a rating. Most theater chains still specifically have rules on the books that can prevent a film with NC-17 from being eligible for showing. In addition, "Showgirls" was the first big NC-17 film specifically designed to exploit the rating, and it failed miserably, giving a nasty stigma to the rating. Ultimately, if you think your film is not likely to score R or below, then you 've got nothing to gain by getting the rating. Meanwhile the rating process is NOT free so there are A LOT of down sides to pursuing rating, especially if your film is a cheap little indie flick.
|
How do TV and radio ratings work?
|
They sample a portion of general audiences mostly. They may use surveys or viewer/listener diaries. Sometimes they use electronic trackers. For TV, it is the Neilsen box . For radio, it is a device called a People Meter, which a listener carries with them and it registers sub-audible codes transmitted by the station.

Our eyesight is generally good enough to survive in the wild, but the demands of modern life make better eyesight desirable. Reading and driving cars is so new as to be unaffected by evolutionOur eyes are evolved to look at things at a fair distance and not a 2 or 3 feet. We also use our eyes constantly for 4-5 hours focusing at very short distances and very bright things. This is creating problems and we are having problems with the eye.

What is the difference between DNA sequencing and Genome sequencing?
|
A genome is comprised of the complete genetic material within an organism. In a human, that includes all of our DNA, both coding and noncoding. When you sequence the genome of an organism, you sequence ALL of the genetic information, and can compare organisms to each other with this genomic map that you have comprised.DNA sequencing is involved in genome sequencing, but you don't have to necessarily sequence all of the genetic information within the organism. You can sequence a particular gene or a specific noncoding region, but not every gene and noncoding region in the organism.So yes, they are different in a way. Genome sequencing IS DNA seqeuncing in organisms such as humans, while DNA sequencing isn't necessarily sequencing the entire genome.Sequencing in general is putting the nucleotides in order. This is helpful for multiple reasons, one being that you can tell the nucleotide arrangement, and therefore amino acid composition and arrangement that can come from a specific gene. Now, we can study genomes, but only if the genome is first built. Genome sequencing is sort of like writing a book. All of the letters must be on the page, and arranged in the correct order, for the book to make sense. We can later read the book, and study it, which would be similar to analyzing the genome after it has been sequenced.

What causes muscle cramps?
|
There can be a few causes of muscle cramps. Muscles rely quite heavily on salts like sodium and potassium; when you're working out and sweating heavily these salt levels can get disturbed and result in cramp. Muscles have a mechanism where they can generate the energy they need without adequate oxygen. The flipside of this is that it generates lactic acid, which can result in a cramp. Finally, things like a change in temperature, over stretching or medication side-effects can be causes of muscle cramps.

In theory what are the major risks associated with harnessing nuclear fusion power?
|
Hydrogen fusion occurs naturally only in the cores of stars. If we want to create fusion power plant, we just have to recreate those conditions. The cores of stars are really really hot and really really pressurized. This in itself is not such a hard problem, with enough engineering we can probably get around it. The reason fusion is so difficult is actually quite basic. Once we have the sun-like glob of hydrogen plasma, we have to hold it in something or it will disperse . There isn't anything on earth we could use to make a container that won't immediately melt/explode etc. So the workaround is either to find "cold fusion" that we can hold in a box of some sort, or to find a way to contain the plasma without actually touching it . Once we get the reactor going, it should be very safe in the sense that it produces no waste besides helium, an inert gas, and requires only hydrogen as an input. However, if someone were to break the reactor somehow, we 'd have to have some mechanism in place for the hydrogen plasma to give off all of its energy without exposing everything nearby to a deadly cloud of superheated gas.It could not work. Today, that's the #1 risk/obstacle. If it works, the capital equipment needed looks like it's going to cost stupendous amounts of money. It will be green, but Nuclear fission is carbon-free and we don't use it more because of how much the system as a whole costs. If it becomes possible to scale fusion up from tiny pellets to substantial chunks of fuel, you're going to have a gas much hotter than the Sun trapped in a magnetic machine. Any field failure will put that plasma in contact with ordinary metal. That will turn the metal to gas and cause a big explosion. Not an H-bomb explosion, a plain old industrial explosion. When 50 people can be hurt and 13 killed in a sugar plant explosion in Port Wentworth, we don't stop using sugar.

How to understand wattage and impedance measurements in amplifiers and speakers when setting up an audio/speaker system
|
I'm no expert, but I sold A/V equipment for quite some time, so I'll take a crack at this for you: We'll start with how a speaker works. There's a cone that vibrates to make sound. This cone is controlled by a wrapped up piece of copper called a voice-coil. The voice-coil can have a positive or negative charge, depending on the type of electricity pumped into it by the amplifier. Depending on the charge, the voice-coil moves the cone creating the right combinations of vibrations to produce sound. The amplifier needs to provide enough power to accurately create the right combination of positive/negative charges to produce sound. If the amp doesn't have enough power to fill the voice-coil, some of the instructions get lost and therefore the sound distorts and doesn't sound as clear. I'm not going to get into impedence because I REALLY don't understand it well enough to explain it properly. I will say if you're spending < 10,000 on a system it does not matter though. Looking at wattage in amplifier specs is hard because it's usually vastly overrated. Look at RMS power, as that's usually the most accurate. 100+ watts RMS/channel is a good level. A good receiver should cost more than $500, preferably more than $1,000. It's the power source of your whole system and it can make shitty speakers sound decent, but a bad amp can make decent speakers sound shitty.

Why does cold water from the sink feel warm if my hands are freezing cold from snow?
|
It's all because you are incapable of feeling temperature. You can only feel a change in temperature. Heat always flows from warmer things to colder things. If something feels hot, it's because you are getting heat from it. If something feels cold, its because you are loosing heat to it. If the skin of your hands is colder than the water, the water will feel warm, because you are receiving heat from it.

Why is gigabit internet useful? Most hard dives can’t write information that fast so why would Someone need Internet that monumentally fast?
|
Gifatbit = 125 megabytes per second, which quite a few hard drives, and nearly any solid state drive, could sustain for a sequential write. And this assumes a single device is completely the entire 1000 megabit per second link. That being said, a gigabit connection far exceeds what most residential users will need outside of small bursts.There's often more than one device in a household that can connect. PC, console, netflix/Amazon tv, phones, tablets. If you want to use two or three of these at that same time the higher bandwidth helps.

Where does the word "girder" in "I am Bender. Please insert girder" come from?
|
A girder is a metal support beam. He is asking for someone to hand him something to bend. As he is programmed to bend things, like girdersA girder is a [steel beam]. Bender was built to bend steel beams in a factory. You'll notice he has his arms out ready for work, bending steel "please insert girder "Bender is a robot that specializes in bending metal girders. He had his personality wiped in that episode, so only the software for his most basic function, which is bending girders, exists inside his cpu, so all he can do is request girders to bend while holding his arms out. It, to my knowledge, has nothing to do with floppy disks.A girder is a metal support beam. Probably the most common form is an [I-beam] named for the shape of its cross-section. It's not slang and to my knowledge is used in all dialects of English. IIRC girders are seen on Futurama as a thing that Bender commonly bends.Bender bends girders. _URL_2_ When a machine wants something from a human, it says "please insert ", normally it's printed on the machine such as "please insert coins". But Bender just says it--"please insert girder" so he can fulfill his main function of bending.Well bender is a bending unit. His main job is to bend things, mainly girders. I don't know if this is what you're asking for though.

Why is Jewish and Muslim more of an identity than Christian or Catholic.
|
It probably just seems that way in Europe and North America where Christianity is so ubiquitous. In places like the Middle East and Asia, where Christians are a minority, they constitute a very distinct identityThat statement is only true in some parts of the world. In countries with a Christian majority, being a Christian is not viewed as a particularly unique trait. In fact, in places like America, going to church on Sunday or giving up meat on Fridays during lent seems normal. Nobody would think twice about seeing someone else do that. However, if a Jew does something similar, like going to synagogue on Saturday or giving up bread for Passover, that seems like the person is engaging in strange, silly rituals. So, to answer your question, in countries with mainly Christian populations, doing Christian stuff seems normal. Doing things associated with other religions seems weird, so those practices seem more memorable and unusual.When Christianity is the dominant religion, it is presumed everyone shares it, so it don't really contribute to defining your identity, unless the way you practice it is out of the ordinary. Muslim isn't really an identity in Morocco, nor is Jewish in Israel.

Why do launched missiles often fail?
|
Try making something weighing several tons travel thousands of miles at hundreds of miles an hour and attempt to make sure it doesn't stray anymore than a dozen feet from its target. If you have little experience in physics, programming, and rocketry it's not going to be easy. Hell a large part of much of modern missile tech was from research done in Germany in WWII. If you don't have access to those resources you're already decades behind.

Why is standardized testing still the norm when a lot of studies say that it is negative for the learning system?
|
First, its hard to drop a system that appears to be doing its job just fine. We've built our educational systems around it and its not that simple to just make it go away. Universities like it because it lets them evaluate candidates much more smoothly. What will replace it? Secondly, politics.At some point you have to determine if a student/teacher/school is better, worse, or the same as the national average. That means that you need to determine the average, then test each student to see where they fall. Basing funding and salaries solely on standardized test scores is a bad idea, but we need to have some way to quantify performanceBecause people who have no background in education call the shots instead of those who work in education. Too many people think that because they were a student they know exactly what goes into teaching.There are just as many, if not more studies saying that standardized testing is a net positive or neutral effect on the learning system. The obvious reason why it's still being used is because there's tons of money put into it, so it'd be hard to get rid of it.

Why is listening to a song in my head not as satisfying as actually listening to it?
|
Humans have great potential not perfect. Mind mimics some sounds, not all. Can recall melodies maybe not harmonies not all at once. Actual recordings clearer, more precise. Can better produce fuller, more intricate, complex sounds. Pleasing to the ear, like a complex dish. Memory of food not as satisfying as eating, is it? Sensory processing preferable to limited, sometimes fallible, memoryI would say because when you actually listen to it your brain is being externally stimulated, having an auditory sensation you could say. When your just listening to it in your head it is a memory. Just like asking why when I replay my birthday party over in my head its not as fun? Or my first kiss not as exciting, or that burger not as tasty, etc. There is nothing quite as sensational as the moment your living in right now. Literally. I am no expert though, just an opinionI actually experience the opposite. I hear songs more amazing in my head than they are in actuality. I usually augment the music and change sounds around and make them sound more how I prefer. As a result, though, a lot of those songs in my head, regardless of genre, end up sounding alike.It's also worth noting that your mind cannot create the actual feeling of the song, so all the sensation from these frequencies is lost.

If there is life after death, why do we value our lives here on earth?
|
Because it's permanent. Whether there is life after death or not, whether it's better or worse, one thing we all know for sure, we can never ever come back to living this life this way. When it's over it's over. And that's something that makes us want to get the most out of it.

What does it mean when they say the Oakland Dept is now "civilian run"
|
Typically when a PD is "Civilian Run," it is administered by someone outside of the department. In Oaklands case, because they currently have no Chief, the department is being run by the City Manager, Mayor, City Council, or an appointee thereof.

Why aren't we changing the routine of human lives for the better?
|
I think we are! It's just a very long term process. Not that long ago, most people were peasants. You go out into the field, toil with backbreaking work all day, and hope you don't get catch plague. Not a very good life. Time passed, and industrialization happened. People had become more productive. A portion of the population started moving from farming to industry. Over time, these laborers started winning rights. The work week had limits , a minimum wage was created, safety laws were passed. At a superficial level, these people were still doing the same thing as farmers , but it was much better. We're still improving. It's just so slow it's hard to tell. But having a real major change, creating a world where nobody _has_ to work, would be really tough. You'd need something like a guaranteed income, where the government gives everyone enough money to survive, whether they work or not. Our society might not be productive enough to support that quite yet. However, as robots and artificial intelligence become more powerful and more common, a guaranteed income will almost certainly happen. Not only will society be a lot more productive and have the resources to support a lot of non-workers, but all the tech might create a high enough unemployment rate that we _have_ to deal with it some how. So we're moving there, it just takes time.

Why are the terms for Mom and Dad so similar across all languages?
|
Those syllables are the easiest for babies to sayIt's believed that the "m" sound is associated with "mom" because it's like an imitation of breastfeeding. Roman Jakobson's idea. With "dad", no idea. Interestingly, in Estonian, it's also "ema", dad can be "taat" . And Russian is also "mama" and "papa". So we can see unrelated languages having a trend!', "English and Spanish derive the word from the same base. You also chose a handful of languages where mom and dad sound similar. There are hundreds of language bases to deal with and not all have similar tones for these words. * Armenian: mayrik / hayrik* Japanese: kakasama / otosan* Finnish: aayiti / isa What you have listed for Korean comes from a modern-enough base to have an Arabic influence. What you have for Hebrew placed into Arabic, as they were easier/cuter to say that the traditional word, as traders worked across the Middle East. Those came into India via those traders, replacing the traditional Sanskrit words for mom and dad: mata / pita . Fun fact? If you say 'mama' in most of India, people will assume you are talking about your uncle, where that is a masculine word. 'dada' is grandfather.Besides the fact that most indoeuropean languages share a common root there are theories that the sounds are quite easy to say and thus were first words babies spoke. However, english, French, finnish, German, Russian, and many more share the same ancestral languageThese are examples of words that have existed a really long time, since before modern languages.

how do choreographers write out choreography?
|
There have been multiple choreographic notations throughout history. One of the most famous is Labanotation, but in my experience, choreographers use anything from stick figures, to shorthand, to coded words for movements. Movements stay in people's bodies for a long time, even after years of not doing it. So they repeat it in their own time to better explain it. Often you'll see a choreographer mark the dance very quickly to remember the next part. They also use their stick figures, shorthand, and coded words for remaining movements. What's nice is a lot of movement names are under a shared vocabulary that all dancers learn through years of training. In terms of preservation of dance pieces over time, video is obviously now widely used for reconstruction, but before video it was basically passing the choreography down through memorization. Every piece I've been in I've either learned through video or physical demonstration from the choreographer or an assistant .

Will the economy ever recover to the point where it was 20-30 years ago when our parents would work 40 hours a week and be able to buy a house and support a family?
|
Being able to afford a home on a single income doesn't really have anything to do with a strong economy. Our economy today is much better than 20-30 years ago. The reason it takes two incomes now is two fold. 1) Increased demand for housing. With two working incomes and very low interest rates, it's easier for the average family to buy a house. This increase in demand drives up the cost of housing, and prices single income families out of the market. In other words, because both parents can work, housing prices have risen to accommodate the extra income. 2) Modern building standards are much more strict than 20-30 years ago. Additionally, the amenities that people want in their houses have increased. Fire retardant materials, better insulation, competent electrical wiring, central heat and air, etc All these things make the houses you buy today much nicer and much more expensive than 20-30 years ago.

When someone dies, why do the headlines say "dead" instead of "has died"?
|
Headlines use active voice instead of passive voice to convey the message, mostly because it has greater economy of words. You can get the message across in fewer words, and that's important for a headline.Takes up less space, allows for bigger print, and is more abrasive. If the headline read "Muhammad Ali has died" you just think "oh, that old athlete passed away". Whereas "Muhammad Ali Dead" seems more urgent and in pores a small notion of something being amiss.It saves on the number of words used so there's more space to have either a larger headline or more text. It'll grab the attention more too.

Can the language you learn growing up affect the way you think and problem solve?
|
This is known as the [Sapir-Whorf Hypothesis]. It was pursued for a while, then fell extremely out of fashion. But now it's back and many linguists admit it is at least *partially* true, and there are a *few* linguists, such as [Lera Boroditsky], who strongly argue for it today. About 50 years ago, people started creating "constructed languages," such as [Loglan], in the hope of expanding the domain of human thought and expressionProbably not. [This article] describes an Amazon tribe whose language does not include a concept of "time" as we 'd recognise it. But members of that tribe have no trouble picking up the concept of time that exists in western languages such as Portuguese when they learn these languages. So the brain appears to have ways of handling things like time, even without having the language to express it. That suggests that, so long as we have a language in which to form thoughts, it doesn't matter what language it is, we'll be able to form similar thoughts regardless. Although there's a fair amount of speculation in that statement.This program on Radio Lab describes a school for the deaf in Latin America where a new sign language was created by the students. The first generation of students didn't have many words for the process of thinking and were unable answer certain rudimentary story problems. Later generations of students whose language was more expansive didn't have this problem. _URL_4_
