What made Nokia phones so invincible? And why can't modern phones be built to be indestructible?
|
Nokia still makes phones, and they're still extremely sturdy. Nokia phones are widely used in Africa, where smartphone penetration is fairly poor. Smartphones can't really be built as strong because they have a big glass screen, and in the Western world smartphones are the norm.

What makes some people run so much faster than others?
|
There are really 3 main factors: genetics, experience, and technique. Genetics is very important Olympic runners generally have perfect lungs and muscles for running, one interesting example is in Jamaica. Jamaicans often have several genes that cause them to be naturally more likely to run faster than average these genes are called: the ACE , and the ACTN3 genes. Also body type is quite important Next the experience portion, this bit is obvious, Working out is essential to being a great runner. The average professional sprinter trains 20 hours each week, and consumes TONS of calories in order to fuel them selves. Usain Bolt ate 5800 calories daily leading up to the olympics and in the months in which he trained which was likely around 25-30 hours each week. In addition to this Usain Bolt is Jamaican giving him a genetic advantage. This also includes respiratory and cardiovascular health Lastly technique, this may not seem important but it can easily give you the leg up you need to win. Posture how high you bring your legs slant relative to the earth arm swing. These are all essential to winning in the major sporting events. Additionally mentality while not the most important thing is still important. Although hilarious this quote from Usain Bolt is an interesting example "I just imagine all the other runners are big spiders, and then I get super scared" this causes adrenaline to course through him giving his another boost and reason to run. Also people with better reasons for doing things generally perform better.

Why is it that my 12-year old dvd player can handle the newest (encrypted) DVD's without a hitch but my 2013 Macbook is unable to duplicate my purchased dvd for a digital backup?
|
Your 12 year old dvd "Player" ? Playing a DVD and ripping a DVD are two different thingsBecause you are not using the right software. You have to use a ripper that plays the dvd while re-encoding it. If you are playing the movie then the video is being decrypted and the encoding software can then encode it. Try handbrake or MacTheRipperProBecause "ripping" a dvd is something most dvd manufactors protect against. Ripping a dvd and playing it are completely different things.

How do movie profits work? What constitutes a film that has "broken-even"?
|
I don't know *all* the finer details behind this, but the general "Hollywood Math" is that movies need to earn double their production budget to break even. One reason is that the studios don't get 100% of the profits from ticket sales, so even if those profits are about equal to the production budget the amount the studio gets is less than that. Marketing costs also tend to be separate from a movie's production budget, so that can add a significant amount of money to the amount a film needs to make to break even in terms of *overall* cost. > If "The Man From Uncle" did make a loss then why is a sequel being considered? If a movie does "good enough" and seems to have a decent-sized audience that would go see a sequel, studios can adjust the budget based on anticipated sales. If the first movie made a decent amount of money but didn't recoup its budget, they can make the next one on a lower budget . Also, some films that weren't very successful at the box office end up becoming more popular over time and make a lot of money off of DVD/streaming sales, and the studios figure these new "late-comer fans" would go to see a sequel.

Why, when a person is sentenced to death does it take decades to follow through on the execution?
|
If you're an innocent person and you get put in jail, it sucks, but at least there's a way to fix our mistake, release you, and pay back some of the damages. It happens, and the state definitely doesn't pay *enough* for that kind of mistake, but at least it's something. If you're innocent and we execute you that's it. We can't fix that if we find out later that you were innocent. And we've had plenty of cases of people who were exonerated after their executions. So as much as possible, we like to be *really sure* that you're guilty as charged before actually pulling the switch. What that means is many years of appeals - lawyers trying to find new evidence to exonerate the accused, or at least to reduce the charges or the sentence. Only once several appeals have failed do we actually set an execution date, so the idea is that we're trying as much as possible to give them a fair shot at proving their innocence, if they can.

How do "entrepreneurs" develop their potentially lucrative ideas without having them stolen by others at any point in the process?
|
Because an idea takes a lot of time and dedication to implement. If someone's stealing it, they're already late to the game and without the initial motivation that started the original idea. Also, it's very common for successful ideas to be laughed at in the beginning, instead of stolen, because we're terrible at predicting what's going to go big. A website to allow strangers to sleep at your place for a few bucks? Right, like that's ever going to work.

Why Did Martin Shkreli Plead the Fifth?
|
Because he may some day be accused of a crime, and doesn't want to incriminate himself under oath. Because, give what a douche he presents himself as, is there anything he could have said the would improve his public appearance? > and the rest is paid through health insurance companies so no one is in fact deprived of Daraprim due to his price increase. Except all the people who can afford health insurance premium because they have to pay jacked up prices. Their money isn't just coming out of thing air, it comes from you and me.

Why don't we get E. Coli from plants grown with fertilizer containing cow manure?
|
Because people usually wash process and wash the plants off, they don't eat plants covered in shit straight from the ground", '"made from" It is not fresh manure. It is composted for a while to break down the manure a bit more and give it time for the harmful bacteria to die. After that it gets mixed in soil, rained on, stirred up, processed even more by the bacteria and fungi in the soul and sits for months until the plant is harvestedIt is possible to get it from plants, but if precautions are taken it is fairly unlikely this article may help []

In military strategy, why is securing the "high ground" vital to victory?
|
The high ground still gives you better vision of the surrounding area, allows you to hide troops beyond the crest of the hill, and moving up a hill is usually slow going, which means being exposed to enemy fire for a longer period of timeThe high ground has a sight advantage. It also has a range advantage. And it has a cover advantage - you can shoot down over cover and obstacles. Imagine if I am in a tower in a city. I can look down and shoot at any of the streets around me. But a person in a street can only shoot within that street or up at the towerBetter vision, better defense, better offense. You the highest vision in the area, so you can see everywhere. It is easier to hold because running uphill has many disadvantages to fighting, as well you can shoot farther if higher. And it is easier to start an offensive because of the reasons listed above.

How does Google & Youtube backup my files, videos, pictures and not deal with hard drives failing all the time?
|
Hard drives are always failing. The drives are in arrays, your data is stored across multiple drives instead of just on one drive. Parity is used to reconstruct data when a drive in an array dies. For an example of parity we can use addition. We know that 1+ 2 = 3. Let's say you erase one of the numbers so you have ? + 2 = 3. Even though we've erased one of the numbers we can calculate what the missing number is using our old friend Algebra.
|
Why do our fingers and toes shrivel/wrinkle when in water for an extended period?
|
This is actually an evolutionary activity. This is an involuntary reaction by the autonomic nervous system. Basically, when we are submerged our skin fills with water losing elasticity and grip. This "wrinkling" allows us to better grip objects under water.

I don't know much but ill break it downYour trying to open a door but it needs a card A Cookie is like a security card for *you* to get in given by a website or more commonly saved passwords A Token however is for a service , its for *non-human* access like other websites accessing other websites that have locked doors using a token to access the door For Example : An App such as Alien Blue has a token to access Reddit Webpage for information and data . Whilst others app that use reddit cant access it without a Token

What in the world is ferrofluid, and how does it do what it does?
|
So remember when you were a kid and you played with this [magnetic hair toy]? Well, the red wand has a little magnet in the end. . The black powdery stuff is iron filings. These like to align in magnetic fields. You can visualize these fields [if you allow filings to arrange around a magnet like this]. So, now ferrofluids: let's break down the word. Ferro is Latin for iron - so it's an iron fluid. There are tiny iron filings suspended in oil or water, generally. So when you apply a magnetic field, there are lots of thing going on that all need to happen in equilibrium. The iron filings want to arrange themselves along the magnetic field lines. The fluid has surface tension and wants to minimize its surface area. . All these things combine and give you really cool patterns, like as seen [here].

Why do hackers focus on government institutions and companies? If they're as anarchist as some claim why don't they do a (modern) project mayhem on financial institutions?
|
Financial institution have too much to lose to leave their systems insecure. Most 'hackers' are just script kiddies that break into soft targets.White hat hackers do it to make the institution secure there data. Alot of the time the data they have can effect innocent people. For ex. A black hat hacker would attack a bank it get people cc numbers and steal money identities etc. The white hat forces the bank to fix the volnerability, by threating to release to the world how they did it.

Why are porn tv channels still around with free porn on the internet?
|
i think that people that are older and grew up without internet porn are just used to those channels and don't want to change to the new fancy free internet stuff", 'Same reason you still get emails from Nigerian Princes and phone calls from Microsoft engineers. People still pay for it*unzips* cuz watching porn on 65" tv is better than watching it on a 4.5" smartphone or a 13" laptop.

what happens if you're doing payments on your car and someone totals your car?
|
If the car is deemed a write off , the insurance will pay you said market value. This has no impact on your obligation to the whoever you bought the car from. So if you owe your dealership 20 grand, but the insurance only paid you 15 grand because that is the value of the car, then you're gonna have to cough up an extra 5 grand! Also, it may depend on any special insurance packages you may get. For instance, there's one that if your car is totaled within the first 2 or 3 years of ownership, then they will actually get you a brand new car. But you would have had to agreed to it and paid a slight premium on top.

Why is k-12 a state issue when most citizens look to the federal government?
|
In the US if the Constitution does not specifically give the power over something to the Federal Government it belongs to the State. Education is not specifically given to the Federal Government so they are only allowed to put a few regulations on it. And what do you mean by "most citizens look to the federal government"? They look to it for what?', "[Assuming you're speaking of the US] K-12 is a local government issue, primarily funded through property tax. The federal government sets minimum standards, which the individual states tend to exceed by various amounts.

Why has the USA seen such a dramatic increase in prisoners while most other Western country have seen a decline?
|
US has jail time for a lot of crimes other Western countries just fine people for. Most of it is a result of the War on Drugs and three-strike laws.I'm not sure that your assumption is correct. The prison population of [England & Wales] ) has doubled in the last 20 years. Britain's prison population continues to increase while the United States has been on a decline for a few years. It isn't as stark in France, but their prison population [has increased] over time. Same in [Germany]. The United States has a lot more people in prison than other countries, but increases in prison populations isn't unique to the United States. Britain's seen a larger increase than the United States.Sentences in the US tend to be longer than other countries. Some countries have sentences for multiple crimes run concurrently rather than consecutively. Read reddit, a typical US response to apparent wrong doing is jail.Many reasons. The Us prison system almost exclusively focus on punishment and not rehabilitation, which leads to higher rates of re offence. US prison are privatized, ie the companies make money on have many prisoners, so they have an incentive to get more prisoners. Which in turn leads them to lobby for harsher sentences. The war on drugs puts a lot of non-violent offenders in prison when it doesn't really benefit society to do so.

Why might equality be a better idea than equity, and not vice versa?
|
It's all to do with the concept of fairness. * **Equality = equal status** is interpreted to mean that everyone has the same 'opportunity' to achieve things and so it is fair. Of course by virtue of hard-work; capability; determination or just pure good luck some will succeed and others will not. In that instance whilst the outcomes for everyone are not equal, it would generally be considered 'fair' because the success of failure of someone is dependent on their actions not their status/background/gender/race/or whatever else. * **Equity = enforce equality** is interpreted to mean that everyone get the same outcome regardless of individual actions and is regarded as unfair. This is for the same reason as above - if I put in more work; or if I have more capability or work to develop myself further it would feel unfair if others get the same outcome in the name of fairness. In that case, what would be my incentive to work harder or try harder or put their skills to good use?

the meaning of " ! " in mathematics?
|
It means factorial. Simply multiply the number by every smaller integer down to zero. for instance, 5!=5x4x3x2x1. 8!=8x7x6x5x4x3x2x1Also the symbol \'!\' can be used for factorial. But in other branches of mathematics it can be used as follows: In logic you can use it to say "There is unique" with the following combination - ∃! In computers it can often be used to signify not equal != or even !a for not a. Quite a versatile symbol!', "'!' means factorial in mathematics, and is recursively defined as: n! = n*!, with a trivial case n = 1 If you're unsure what *recursion* is in mathematics , you plug the numbers into the function until you reach a trivial/base case. 5! = 5 * 4! 4! = 4 * 3! 3! = 3 * 2! 2! = 2 * 1! 1! = 1 Combine all these equations together, and you get: 5! = 5 * 4 * 3 * 2 * 1 The non-recursive definition is just: n! = n * n-1 * n-2 * * 3 * 2 * 1 Keep in mind 1! is always 1, but 0! is also always 1. There are no non-positive, non-integer factorials, or *there are*, but it's excruciatingly difficult to explain. There is an almost certainty you'll never come across factorials outside of Z^+.a better explanation for factorial is that n! represents the total number of methods you can arrange n number of discrete elements. lets say 3 elements name a b and c abcacbbacbcacabcba = 3! = 6 methods of arrangement. but the way to calculate it is of course multiplying the natural numbers together up to n.

What happens to adrenaline once its in your system?
|
Adrenaline is released by the adrenal gland in your body. Almost everything is your body can use adrenaline . The effects you feel under stress are caused by the release of adrenaline, so once you feel it, your body's already used it. Once your body decides there is no need to be stressed, adrenaline no longer gets released. I say "under normal conditions" because people who suffer from anxiety have a release adrenaline, which then causes even more anxiety, releasing more adrenalineAdrenaline is a hormone that at is consumed rapidly and directly into the cells of the blood vessels themselves. The release of adrenaline is very quick and not generally sustained because it has such a short half-life in the body which is around 2 minutes. It allows your body to increase blood flow and the amount of oxygen that goes into the muscles; so your body isn't using the adrenaline as fuel, it is using the increased oxygen levels that are provided by the physiological effects of the epinephrine/nor-epinephrine. This allows you to lift things with relative ease, sprint faster, and even process information at a higher rate In short:-Your body uses it all up in it's 2 minute half-life-The physical exertion is a result of the epinephrine causing physiological changes-Your body does not pump out continuous amounts of the hormone because it is so potent and the adrenal gland is not very largeAs to your "will the body keep releasing adrenaline" - I am not any sort of medical practitioner, just a panic attack sufferer, so I may be wrong, but we are often told that this is not possible. There is some kind of self-limiting aspect to panic attacks, after a while, even if you stay "anxious" the biological effects will just stop on their own, because your body can't keep it up forever. Most people tend to want a nap at this point.

How does the 3D on the Nintendo 3DS work?
|
What you are actually looking at is two separate screens in one unit . well, technically three as there is the non-3D screen too, but lets ignore that The 3D screen of the 3DS is actaully two screens in one. One screene points towards your left eye, the other towards your right eye. It will play even frames on the left screen, odd frames on the right screen. This tricks your brain into percieving depth, as it happens so quickly that you cannot see it flicking from one to the other, your brain therefore sees the two images in stero and boom 3D. However, its also that switching which makes you feel ill. The frame-rate is not high enough to totally fool your brain, it kinda works, but if you use it for a long time your brain is still processing left, right, left, right, left, right, left, right over and over and this makes you feel a bit odd. It effects some people more than others. When you are looking at a real object in 3D, you are not doing this quick left, right, left, right switch over as what you are looking at really is three dimensional.

why is Volkswagens false emissions test hurting the company's reputation more than other more serious recalls that have killed people?
|
It is not that emissions are more important than a human life. It is the fact that in this case, it was a very purposeful lie. And it makes people wonder if they are lying about this, what other things might they be lying about that might directly affect their safety. To some degree, people accept that production errors can happen, but it is the way the company responds to them that makes the difference. If they cover it up, it'll have more of an effect on their reputation than if they immediately set in order a recall once they have spotted there is a systematic failure.

What does North Korea's attack on South Korea mean for me?
|
What it means right now: North Korea and South Korea are having another dispute with North Korea puffing itself up like it usually does. What it could mean in the future: A war between both sides that could potentially ruin both Koreas, and possibly American intervention. If America does intervene in the possible war, it probably won't directly affect you, but would affect you the same way the war in Afghanistan does.

What "Real Hacking" Is
|
Exploiting a computer system requires you to first identify a vulnerability. To be able to find a vulnerability in a program that you don't have the source for requires a person to know about all different kinds of vulnerabilities and be able to spot them by testing or by examining the program using special tools like debuggers and decompilers. Once you have found a vulnerability, you have to figure out what you can do with it. Maybe there's a way to make the program crash. Maybe you can get access to parts of the computer that are supposed to be protected. It takes a great deal of patience, knowledge, and skill to do this. Sometimes a vulnerability becomes very well known and information on how to exploit it becomes public. Using that public information, a person with much less knowledge and skill could exploit the vulnerable software just like if they'd figured it all out for themselves.

In cases of mass shootings with one perpetrator, why do witnesses often report seeing multiple attackers?
|
Gunshots are very loud. That means that they echo in situations where other sounds wouldn't have audible echos. They hear shots from several directions, and tell that to the police, who decide to play it safe and act as though there are multiple attackers.It is not easy to identify who is on what side. People run around, sometimes in the wrong directions. Echos can make it sound like there are gunfire coming from multiple directions. It is hard to get an accurate description of the people you run away from, even if they are not shooting at you. So you often do get reports that indicates multiple attackers in addition to the reports saying a single attacker. The safe bet is to assume there are attackers that you do not know about. This way you do not get another mass shooting just as police say everyone is free to return from their hiding spots.

How are "knots" formed in trees?
|
Woodworker here. /u/cnash is right about knots caused by branches: the branch wood is flowing at more or less right-angles to the rest of the trunk; the grain in the main trunk has to flow around the intrusion that is the branch, creating the characteristic "eye" pattern of a knot. Woodworkers tend to dislike knots because the knot wood is both unstable and more difficult to work . /u/cdb03b is right about burls: they are areas of "disorganized grain" caused by a variety of factors. Infection and infestation are two, but there are probably others as well. As far as I know, the actual etiology of burls is not fully--or even all that well--understood. Woodworkers tend to love burls because the disorganized grain induces a lot of "chatoyancy" in the wood, in which light appears to dance and play within the wood, and looks super-cool when the wood is properly smoothed and finishedMost often they are the point of an infection or infestation and the trees version of an immune system seals off that area from the rest of the tree to protect it.

Why is censoring a vehicle's license plate important for privacy? It's not like we can't see everyone's license plate already.
|
The chances of a person jotting a license plate down while in traffic is a lot lower than if you have a static image you could reference.
|
Why and how do Lumbricus terrestris (rain worms) simply appear during rain?
|
They sense the vibrations, and they crawl up to the surface. Worms need to be wet in order to breathe, so they can't survive on dry land. If it's wet, they come up because they "know" they can move around freely on the surface without dying. A lot of birds exploit this fact by hopping around on the ground and tricking worms into thinking that it's raining.
|
When we drink the juice of a fruit, what are we drinking? What does the juice do for the plant?
|
Fruits are usually bait. The plant puts sugar and water in it to tempt some animal to come along and eat the fruit. In exchange for this food, the animal then distributes the seeds from that fruit elsewhere allowing the plant to spreadThe fruit tastes good so you eat it. The plant is trying to get you to eat the fruit with its promised goodness. Good fruit gets eaten often and the seeds survive the digestive process and are ready to grow into more fruit trees when you poo.

Would using a local anesthetic like lidocaine help with the burning from hot peppers like habaneros?
|
Interesting idea. I'm not sure if it would or wouldn't help. I will note that milk doesn't counteract the pain or heat, at least that's not its primary function. The hot substance in peppers is an oil which doesn't mix with water. Milk contains fats that will mix with it and wash it away. Normal soap is also somewhat helpful, but milk is one of the only things you'd want to put in your *mouth* if the burning issue was caused by *eating* a hot pepper. Lidocaine might help on skin, but might not be safe to use in your mouth .It is a terrible idea to coat your throat or tongue with lidocaine. You can very easily loose the ability to swallow and then choke to death.

Why do online newspaper use a paragraph for each sentence?
|
This is what they teach in journalism schools. A paragraph should only contain one idea as readers would get bored with a wall of ink.

Can someone explain how drug control rooms help drug addicts?
|
How do they help addicts? They provide a safe environment, usually with clean needles, in which to use. There's medical attention nearby in case of OD. Most importantly, it's an environment where users can be exposed to *help,* where they can ask for help, where they won't be arrested or judged.

what does it mean when payments shall be made by the company in arrears at the end of each month of services?
|
> Does this mean I will be pay on Jan 5 Yes. "In arrears" means they pay after the work is done, not before. They have 30 days after you submit the invoice, which comes after the work is done. > What do I do if they pass overdue and when will should I start inform them that they're overdue, in advance or later? You inform them they're overdue once they're actually overdue. If you invoice them on December 6, you shouldn't say anything until January 7.

How come artificial sweetener can be used in diet soda to reduce caloric intake but cannot be used in chocolate?
|
You could use artificial sweetener to reduce the calories in chocolate but a large number of calories from chocolate comes from all the fat that's necessary to give it a proper texture. This is a problem you have with most solid foods - there's few things you can use to give them volume & body that can pass through your body without problems. Drinks are easy because they're pretty much just water + flavoring.It has to do with the function of the sugar. In soda the main function of sugar is to make it taste sweet. In chocolate sugar also gives structure and texture.

Why do MLB games start at random times like 7:05, 7:10, 7:40 etc., instead of just starting at 7,8,9,etc.?

Why do Snowflakes have a 6-based symmetry, and why is each one unique?
|
Caltech has an excellent primer [here] but basically, the molecular structure of water itself leads to the 6-fold symmetry, and the fact that no two are exactly a like is a result of tiny imperfections in the crystals as they grow, combined with the staggeringly [huge] number or possible shapes.

When/How did peanut allergies become so prevalent?
|
Pediatricians in America advised against nuts since they represent a choking hazard. An indirect effect was that children's immune systems were not exposed to nuts during its development. Once developed, their immune systems reacted, violently at times. The American Academy of Pediatrics just recently realized that in other countries, nut allergies are very low, so they reversed their position on nuts and recommended introducing nuts in an easily digestable form as early as 6 months.

How does prizes like "Win Pespi 4 LIFE!" work?
|
It all varies on the prize. Sometimes they give you a huge upfront amount that they call a lifetime supply, sometimes they dole it out every so often in instalments, sometimes they get you to ring up and ask for more when you run out. It's not going to be an unlimited supply though. It's rarely bad to win a life time supply of something, regardless of how they're getting it to you or how much a life time supply turns out to be.Just enter their pepsi-cola diabetes4life sweepstakes If you win they will come hook you up to an iv so you can wheel it around with you intravenouslyWow. For me that would be, 7 Pepsi.

Why does it hurt our eyes to look at something that is bright?
|
Human eyesight evolved in a specific environment to serve a specific purpose, so eyes are attuned to the needs of that environment. Eyesight is merely a light collection device, so any light spectrum greater than the normal range can damage these sensitive tissues. A pain reaction serves to avoid damage and is therefore a necessary biological function to protect eyesight. This is also why filters are needed to photograph bright light such as the sun. A normal camera lens functions within specific ranges attuned to human eyesight since being viewed by humans is the purpose of a camera.
|
Why did we come up with Magenta, Cyan and Yellow for printers instead of Red, Green and Blue?
|
It's the difference between additive coloring and subtractive coloring . The paper is white so by using Magenta, Cyan, or Yellow you are using the ink to "hide" portions of the white coloring thus allowing the unhidden portions through. If you used all 3 the result would be black, but black ink is simply used for this instead. Using magenta and yellow for example obscures everything but the red light so the result appears red when you put Magenta+Yellow ink on a spot. In RBG coloring there is no white paper so you are simply adding red, blue, and green together in mixtures to get any color you want. If you use them all you get white, if you use none you get blackone is subtractive colour and one is additive subtractive = add colours to take away from white to make black additive = add colours to take from black to white for printing you use subtractive as the more ink you add the darker colour will get until it reaches black if we used RGB then it would be impossible to print the colour cyan as it is a lighter colour than blue and as i just stated a printer can only print things darker than starting colours never lighter for computer screens it is diffrent as you start with black and add lights until the colours become brighter the more light you add the closer to white you get so thats why it uses RGB as they are the darkest to start with

Why would estrogen and progestogen in birth controll pills decrease fertility for women instead of increase fertility?
|
The important thing to know is that the menstrual cycle is just that, a cycle. A series of things happen in the right order, repeatedly, and that allows for ovulation and fertility. Hormones are particularly weird in that different levels, or a pulse vs. a constant amount, can have very different effects. Disrupting the cycle with constantly elevated progesterone and estrogen can prevent ovulation. At low constant levels, estrogen and progesterone provide negative feedback that decreases production of follicle-stimulating hormone and luteinizing hormone, which are required to stimulate development and release of an egg. The best way to show the influence of hormones on the menstrual cycle is, pun intended, a flow chart: _URL_0_ You'll notice that this chart has estrogen stimulating LH. Oddly, while a small amount inhibits, a large amount triggers the surge in LH that triggers ovulation. Hormones are weird.

Why isn't mouthwash a good enough substitute for toothpaste?
|
Toothpaste is a mild abrasive.This means that it is better at scraping, specifically scraping plaque from the teeth.

Movie Volume - Action scenes VS dialogue
|
It's more of a side effect when converting from surround sound to stereo. Because surround has 7 speakers around you, each one requires less volume to make a large total sound. When you compress these 7 speakers into 2 for stereo, the action sequences that use all 7 speakers normally, get compressed into two speakers and are made very loud. While the dialogue scenes with only 2 speakers being used initially, are not compressed so they are at their initial volume which is very quiet compared to the action scenes.

Why do optometrists and opticians refuse to tell me my pupil distance?
|
If they give you the PD value, then you can go on-line and buy glasses for a tiny fraction of the price which they would like to sell them for. Without the PD value you may have the right prescription on the lens, but the lens will not be in their ideal position on your face which causes distortion. You might be able to get a close number by using a friend with steady hands and mm ruler. I saved about 90% on my second set of glasses by going on-line .

How can a video have more likes than views?
|
Videos are stuck at 301 because YouTube starts to change the way they count views and they check the video starting after 300, so videos will often get stuck at 301 because it's the first number after 300, then youtube had to process it on their end before they start to count those views

Why do schools still insist on standardized tests even though all the teachers and students find them to be dumb?
|
Pretty simple. Because they are easy to grade and organize students based on a score. There are much better ways to gauge learning, but they require a lot more time and effort than filling in bubbles and running them through a machine.So yes there are better ways to measure success in school, but if you are trying to come up with a way to measure success and the people complaining about them are already rating 'low' on that scale are they really the people that should be designing how successful they show up on a scale?", 'You want state funding? You get scores the state funding committee can easily rate. It's not about educating the children, it's programming them to give up the biggest part of their day for something they "have" to do.As much as I appreciate dedicated, creative teachers and what they've done for me and my kids, school is ultimately about learning things. Standardized tests are a good way for students to show what they have learned.

How does rolling something between your hands produce an almost perfect sphere?
|
Imagine starting with a cube-shaped chunk of play-doh and rolling it in your hands. The corners get smushed, because they stick out. There are still some edges that stick out though. If you roll carefully, you'll eventually smush down all the corners and edges without making new ones. A shape that doesn't have ANY corners or edges is a sphere!", 'The key is that you progressively redistribute the bits that stick out the most to other places. If you compress too much you will get a cilindroid because you are redistributing more than just the outermost bits. An object where all the bits are at the same distance from the center is a perfect sphere.

How can people die from skin cancer? Why can't the cancerous part simply be cut away?
|
Cancer is cancer because it spreads. If its a benign tumor or you catch it early enough then you can easily cut away the affected area and everything is fine If the tumor metastasizes then your melanoma can go from tumors on your skin to tumors in your liver or kidneys or lymphnodes. These tumors will also grow and spread throughout your body. Now you've gone from cancer on your skin to cancer throughout your body which can't just easily be cut out, this is where Chemotherapy and full body radiation come in as they attempt to kill all the pesky cancers that have spawned around your body.

What is the reason for car alarms going off due to vibration?
|
10+ years selling/installing alarms here. It's not a vibration sensor, it's a "shock" sensor. 504D is a common part number. It alerts the owner to an impact. For instance, your ex taking a Louisville Slugger to both headlights, or a thief smashing a window. Things that wouldn't trigger the alarm if it just went off for an opened door/hood/trunk. It's also a deterrent, thieves know to tap a car and see if it chirps. No one wants to stand there while an alarm goes off. The fact that it goes off for a severe vibration is a side-effect of a poorly adjusted sensor. They do have a sensitivity dial, and most pro's set it at a point where you need a *real* impact to set it off. Out of the box, it's often way too sensitive.

How exactly did ISIS form and why does Reddit say their formation is because of the United States?
|
ISIS formed due to the power vacuum caused by the Syrian Civil War. They were one of the more competent groups, and as such, more and more people joined their ranks. The more people they gained, the bigger their ambitions got. Eventually, their ambitions outgrew the organization they were originally part of; Al Qaeda. Reddit says ISIS was formed as a result of the power vacuum caused by the US' invasion and occupation of Iraq. While a large number of ISIS' fighters **are** former members of Saddam's military, the reason they were able to gain so much territory so fast, was because Iraq's former PM, Maliki. The US saw the risks posed to Iraq from ISIS long before the US left, which is why the US asked to stay longer, but Maliki refused. He stated his military was strong enough to handle any threat, and that the US was fabricating threats in order to continue to occupy Iraq. Once we left, Maliki began to considate power, and began persecution of the Iraqi Sunni population . He even blamed the Iraqi VP, Tariq al-Hashemi , of organizing a suicide attack, further dividing the Sunni-Shiite population. Once ISIS invaded Iraq, Maliki's government failed to act appropriately, because they were more concerned with possibility of the Kurds expanding their territory/declaring independence, than they were ISIS which only allowed ISIS to expand to the gates of Baghdad itself. If it wasn't for Maliki's incompetence, greed, and corruption ISIS wouldn't have ranks flooded with Iraqi Sunnis, it wouldn't be at the gates of Baghdad, and it would simply be another small player in the Syrian Civil War. So while the US invention eventually led to the environment that allowed ISIS to grow, the US also attempted to take the appropriate steps needed in order to prevent ISIS from expanding, but Iraqi politicans continuously took steps that only added fuel to the fire.

fluoride ingestion vs fluoride topically on teeth
|
> Will fluoride ingested orally react with HCl in the stomach? No. Fluoride is F- and it will remain F- when it's in your stomach. It doesn't react with anything there, especially at the very very low concentrations you'd find it in water and other drinks. > Every time someone say fluoride is safe, I wonder how it travels in the body until it gets to teeth. Please eli5 :) It actually goes straight from your mouth to your teeth. This is why Fluoride toothpaste and mouthwash work even though you don't swallow them. For the purposes of tooth health, there's no reason to swallow it. However, there's not really any risk to swallowing it as long as you don't swallow A LOT of Fluoride every day for a long time.Firstly no reputable published study has ever found Fluoride to cause damage to the body at appropriate levels. Fluoride toothpastes perfectly safe for daily use, however it is recommended that you do not swallow toothpaste and instead spit it out. Fluoride is a very helpful chemical in toothpaste as it kills bacteria and becomes directed incorporated into the tooth enamel. Enamel is a crystalline substance made almost entirely of hydroxyapatite 62). The fluoride from toothpaste acts directly on the teeth without travelling through the body. When you consume acidic foodstuffs , the dissociated hydrogen atoms attack the hydroxyl ions in the hydroxyapatite and removes them from the crystalline matrix. When you brush with a flouride toothpaste the fluoride substitutes into the hydroxyl depleted hydroxyapatite to form fluoroapatite. Fluoroapatite a harder material, more resistant to the acids caused by bacteria in your mouth. Therefore by using fluoride toothpastes you can partly counteract* the effects of a sugary diet damaging your teeth by remineralisng acid damaged enamel. So in summary, proper dental fluoride use helps teeth by entering the tooth structure to improve and heal it without travelling through the body and without side-effects. Hope this helps :D

What would it look like if we could see radio waves?
|
Phones and wireless access points would all glow, and their light would stream through walls like light through a lampshade. Radio towers would do the same, like distant lighthouses through a fog. All phones would be the exact same color, but the wireless access points would all be slightly different shades of the same color. The radio towers would each have it's own color. Radio also bends around objects well, so corners would light up just a little bit, like the corners of a glass fish tank with a light inside.

How come I can drink milk just fine during the day, but if I do it at night I wake up with horrible stomach pains?
|
Maybe you're somewhat lactose intolerant. Since digestion slows down at night, it could be that your body doesn't produce enough lactase to digest the lactose sugar in milk. Perhaps your body has JUST enough lactase when your digestive system is most active during the day.

Why do so many stores require a minimum amount of purchase for you to use your credit/debit card? (Usually a $10 minimum or so).
|
The fees to operate the machine can usually seem exorbitant. Especially in smaller towns, you'll see some credit card reader companies charge a base fee per swipe and then a percent of total cost. Basically, if you spend less than $5, some places could technically lose money when all costs are accounted for.It costs stores money to process a credit card. If your purchase is below a certain level that fee is often the entirety of their profit margin on the products you are buying and sometimes more for some products. As such they set minimum purchases to ensure they do not lose money on the sale to you.Credit card companies make money off vendors by charging a percentage of the commission. Therefore, some stores want to avoid credit card payments for low amounts so that they don't lose a large percentage of the revenue to the card company. Source: Am a small business owner.

Does the human brain have a "refresh rate"?
|
We haven't seen any significant evidence thus far to conclude that it does. Part of the issue is the brain just isn't organized enough for any kind of cohesive, system-wide refresh rate. That said, individual nerves have a resting period in between signals in which they are unable to fire , so there could be an argument for such a phenomena when looking at small nerve systems.

How Priceline can have a name your own price option while other hotel sites dont
|
They set up an agreement with properties to offer different levels of pricing for the same room types. They can list the same room inventory as costing $50, $75, or $100 and when you name your price they pull from the closest inventory and pay the difference. There are only a limited number at each price level however.Often, Priceline is lower than competitors because they have dramatically reduced their commission rates. Other sites may have the exact same price available but have higher overhead costs and require a greater commission. Certain properties do have exclusivity agreements with OTAs , but OTAs can also include parity in the contracts which prevents the property from giving a lower rate to a competitor.

If the economy is getting better, why is it so difficult to get a job?
|
To my knowledge we only solved the unemployment issue by creating low paying jobs, like technical and blue collar. But we didn't help the middle class which is the heart and soul of a countries economy. [Edit] to add-on this was what the last administration did. We have yet to see how the new administration will and what to do.

How come Doctors don't get sick more often?
|
First, I think it depends on the sort of medicine that you practice. If you're a specialist, like a cardiologist, you probably don't see so many cold and flu cases. If you're an ER or family medicine doc, that may be a different story . There are protocols that medical staff like doctors and nurses have to follow to protect you and themselves from illness. For instance, they're supposed to wash/sanitize their hands when they come into the room to take a look at you. That's as much to protect themselves as to limit spreading patients' germs. Medical professionals are also required to get vaccines like the flu shot and Hep B - no exceptions. Having a disproportionate number of physicians and nurses in my family, I have to say medical professionals **do** get sick more often than us regulars. Just a recent example: My brother got some sort of weird-ass viral infection he's been fighting for about 4 months now. He's not contagious, but it's something he picked-up from a patient. It's affecting the nerves in his ear, so he's having a terrible time with vertigo and his balance. He told me it affects about 100 people a year. Forget what it's called. Not life threatening. Just very uncommon. The local virologist figured it out.

How the Affordable Care Act will actually increase my insurance premiums by 56%?
|
The specifics of any particular premium change are going to be complicated, but the biggest factor that the ACA would have to increase your premiums is by requiring a different standard of coverage. The ACA sets minimum standards for a plan to qualify and your plan may not have met those standards previously. Your plan may have excluded many types of care which must now be provided, it may have had very high deductables which you would have had to pay in case of illness which now have to be lower, or the plan may have had relatively low caps on yearly or lifetime coverage which must be lifted. These changes can be particularly expensive if your insurance pool is particularly small and/or risky. If some of your coworkers have expensive chronic conditions which now must be covered, your premium--combined with your other coworkers--is paying for their health care, but somebody in a pool with less cost and risk is not. One of the goals of the ACA is to normalize the payment of health care and reduce the risk of financial disaster for people who utilize services. Many people in need of health care, but who lack insurance, end up utilizing services in very inefficient ways, such as going to emergency rooms for simple or manageable ailments. Costs associated with medical conditions are a leading cause of credit default and bankruptcy. The thinking is that no insurance, or inadequate insurance is a major problem in controlling medical costs because it leads to situations where nobody has an incentive to reduce risk or cost.

The difference between global warming and climate change if there's one?
|
The terminology changed to be more broad. Global warming was what we figured out first, then someone went "oh wait, because the planet is getting *overall* hotter, that makes the weather do weird things. It's now rainier over here than usual, drier over there than usual and a couple spots are even snowier than usual, even though overall it's too hot! We need to change the word."', "Global warming is what it says. Average warming on a global scale. Climate change is what it says. Any change in climate trends. Currently climate change is in a warning trend. Aka globally it's warming. Today when people speak about climate change, they are usually referring to global warming.

How does a software company offering a "free student subscription" know you're a real student?
|
The answers here are correct, but I want to add: Autodesk doesn't actually care a whole lot whether you're a student or not. Autodesk makes all its money selling software to businesses. These businesses can get in serious trouble for violating the EULA of their software . It's also very hard to get away with; all software made in student software is flagged as such, so it'll quickly become apparent to those you do business with that you're effectively stealing. If you're not actually a student but just some random shmuck who wants to learn CAD, Autodesk is actually happy to help; if you manage to get a job with it, that will just encourage the employer to then buy the software that you're familiar with.I know for Amazon prime they ask for a "student email" but that is a pretty shallow form of conformation.They simply don't care. To do any real business you need to buy a business license. In addition, it get's their software a userbase.Typically you need a .edu email address at an academic organization partnered with the software provider.Most of the time they just ask for a .edu email address, which of course doesn't always prove you're a student . It's not foolproof but it's easy. Another way I've seen, which was for student membership rather than software, was to require you to send in a copy of your ID, transcript, enrollment record, or some other evidence. This is more accurate, but takes more time to verify.

Why do we still use propeller planes in the Air Force?
|
Turboprop engines are far more fuel efficient than jet engines, and more reliable in unimproved areas with lots of dust, sand, grass, and rocks. So they are the engine of choice in applications where speed is not valued, but reliability and cost per mile is highly valuedthey use less fuel and can fly slower making them good for maintaining a presence above the battlefield. they are good for trips where speed is not that important or going slow is helpful like p-3 sub hunters[Useful chart showing the relationship] TSFC - Thrust specific fuel consumption. Lower number indicates greater efficiency. Bipass - Ratio of air accelerated by the prop/fan : air used for combustionMany reasons - fuel efficiency, ease of maintenance, ruggedness, Short Take-off and Landing , cost is a big one, and the propeller on a turboprop aircraft is far more likely to dispense with a bird or a stone than the fragile blades in a turbofan engine. Props will not be phased out in the forseable future as they play a fundamental role in aviation. *spelling_URL_1_Some german pilots came to the aviation academy I work, on this one ! Bigger than it appearsThose type of aircraft are used more or less exclusively in the north. I am not an expert. But, from watching documentaries and such. Especially the C-130s can fly in hurricanes, or just about any type of weather you can throw at them. Taking off and landing in difficult situations. A true marvel of engineeringFrom my understanding, a big part of the reasoning is to avoid damage to the engine when planes are landing in rocky/dusty areasIn addition to reasons already given they are cheaper to buy and operate than jets, making them ideal for training.

Why can't the UN intervine in whats happening between Palestine and Israel?
|
The UN doesn't have the kind of military force necessary to invade Israel - even if they managed to pass such a vote . Moreover, what would that accomplish? The Palestinians do not have a functional economy or government. They're almost entirely dependent on Israel for all of their infrastructure. I suspect Israel's desire to continue providing that support would be diminished by an invasion. You also have to consider the fact that what you're suggesting is that foreign powers expel the people living on those lands - who have been living on those lands for generations - in favor of what is essentially an invading force. It would be akin to the UN invading the U.S. to hand California over to Mexico.

Why is a broken leg a death sentence for a horse?
|
Horses must be able to have even pressure on all 4 legs. They have very poor circulation in their legs and need their feet to be on the ground to keep the blood flowing properly. When you have poor circulation or none at all, tissue starts to die off. This is why horses must be able to stand on all 4 legs. If they put more weight on another leg to compensate for a hurt leg that can cause laminitis which is extremely painful/deadly', "Because a horse really doesn't have an option of not being on its leg. A human can put an arm or a leg in a cast and avoid putting weight on it with a walker. A pet can be carried around and kept from putting weight on the leg. A horse, however, cannot go about its most basic tasks without putting weight on the leg, so the leg will not be able to heal.

Why/How can gas stations place a $125 hold on my account when I buy significantly less than that amount of gas?
|
Credit card pre-authoritization-- it is how credit cards work. Gas is a metered sale. Most times when you shop at a merchant, you pay with your credit card and it is approved/declined on the spot. "Pay first." Gas stations, by habit allow you to fill up first then you pay-- the problem with this is if you do not have enough money to cover the transaction then the gas station loses money, the product could be contaminated or not resell-able and they will not be able to "force" you to pay. So, they pre-authorize your credit card for a preset amount-- $125 was set by that individual gas station location, so if you were to continue to get gas until the price was $125, the pump would shut off before it became $125.01 forcing you to reswipe your card for safety measure. So now theres pre-authorization, the merchant set on your account $125.00, but you only bought $50 worth of gasoline-- there is usually 24-72 hour limit until the business does "settlement" which tells the credit card processor that you only bought $50. The transaction gets revised from $125 to $50 and your bank will then release the funds instantly back to your account. This is also how deposits work at hotels too. Picture of how this works:_URL_0_

If blueberries are blue and blackberrys are black, why are strawberries not called redberries
|
There are more berries that aren't named after colors than that are. So maybe your question is "why did we give a couple of berries names that are as bland as their color?" Strawberries are frequently covered with straw during their overwinter process to keep them warm enough to not die, protected from the elements.1) Blackberries aren't black. As black is the absence of colour, they're actually a very dark shade of blue. 2) Strawberries aren't called redberries as historians believe they grew by straw in the woodlands - but this isn't entirely accurate.

Why hackers can access database from big companies but can't access Google's search algorithm?
|
Are you so certain that people have not hacked or have access to these materials? I'm not so certain. Hackers don't announce their hacks 999/1000 times. They don't make it public. Why would they? That just means people will know they got hacked, fix the problem, and try to find the hacker. Or the hacker could just shut up and continue doing whatever they are doing.Google is probably better at keeping their servers secure than a lot of other companies. Being a big company is not the same as being a competent company.

Why does each piece of a broken mirror have its own reflection
|
When you break a mirror, you multiple smaller mirrors. Unless those mirrors are oriented in exactly the same way, the light will bounce off of them at a different angle and give you a different mirrored image. If they *are* oriented the the same way, they will still reflect the same angle back at you.> [ ] even though light and everything is still hitting the same spots at the same angle It's not the same angle though, only nearly the same angle, if you mirror coat a subtly faceted surface you get the same basic effect, without the cracks. Whichever angle you look at a broken mirror from it's still cohesive in the sense that with the same light you'll always get the same reflection from the same angle, only now it's gathering light into a discontiguous reflection. The illusion of every piece containing an entire world is just because you're moving around and seeing reflections from different angles. You have to think more carefully about what exactly you mean by 'cut'. If you cut a mirror from top to bottom with perfectly matching edges and both halves remain on exactly the same plane, you won't even notice the difference.

why do people get so passionate about their sport's team when they are technically not affiliated with them?
|
from what I've seen, a lot of people think of their sports team as direct representation of the region they live in/are from, and are trained to see it that way since childhood . you see this a lot with teams based in smaller cities, like the Green Bay packers, because as a smaller community it really brings them together as a community and also kind of puts them in a national spotlight where they wouldn't be without the team. it's just like a pride thing I think, kind of like people who really identify with their country of origin.We are a tribal people and like to identify with groups. Sports is an easy, shared tribal experience where me and those around me get to prove we are better than your tribe, in a very constrained way with clear winning and losing. It is a tiny war without death.

Why can't we attach a 100X microscope to the eye piece of a 100X telescope and get a 10000X zoom?
|
It's really hard to answer this in an ELI5 manner, there's a lot of complex optical physics in play. What is important in optical systems, particularly when you are talking about 'zoom' is resolution. By resolution, I don't mean how many pixels are on your screen, or how many megapixels the camera has. It is, the smallest details which can be resolved. The classic example used to illustrate resolution is car headlights. When the car is moving towards you from a great distance, at what point do you stop seeing a single point of light, and start seeing two distinct points of light? Without getting into the complexities, the resolution of an optical system is determined based on the size of your objective. This is why telescopes used to look at deep space objects are so large. In your example, while you may very well be able to obtain 10000x zoom, you will have extremely poor resolution so will not actually be able to see anything at all.

Why is it when i'm in a completely silent room somehow I can hear some buzzing?
|
What's going on here is tied up in the function of your brain. The human brain is an immense pattern-matcher, taking in external sensation and giving it meaning, matching it to other things it knows. It's not used to getting *nothing* from its environment. The human brain gets so starved for sensory input that it will make up its own, similar to how you can start to see color if you close your eyes for a long period of time.

Why do all the planets in our Solar System orbit the sun in a latitudinal path/on the same plane?
|
A nebula ie a cloud of gas starts to collapse. The conservation of angular momentum result in that is spins. If you have a spinning cloud with particles that travel in random direction they start to collide. A spinning direction will be dominant and a disc start to form Particles that have a another orbit then the disc will pass trough it and collide with it. so the only way to orbit and not collide is to be in the disc. Planets are formed in the disk so they will all be in the same plane.think of it like this. gravity causes the planets to fall *towards* the sun. momentum causes them to fall *past* the point at which they'd fall *into* the sun. that's how an orbit works. thing is, that also works in three dimensions, not just two. if they planet is above the ecliptic plane, gravity is going to cause it to fall towards the ecliptic plane.. slowly, and surely, and only when there's a planet or two in the ecliptic plane when they're in the right area, but there IS a force pulling them into the plane, and there's nothing resisting that force ._URL_0_ as it shows in this video the sun is moving through space dragging us along so if the planets orbited longitudinally they would need to reach some pretty ridiculous velocities to over come the suns already ridiculous velocity at 500k mph. Longitudinal movement makes sense in a stationary model but one you add the suns movement it becomes impossible

How do those bladeless fans work?
|
The pedestal of the fan contains a brushless electric motor that takes in air and feeds it into the circular tube. Air flows along the inside of the device until it reaches a slit inside the tube. This provides the basic airflow that creates the breeze you'd feel if you stood in front of the fan. Dyson claims that the Air Multiplier generates a breeze with 15 times more air than what the device actually takes in. There **are** blades in the fan -- you just can't see them. The pedestal hides the blades. A motor rotates nine asymmetrically aligned blades to pull air into the device. According to Dyson, these blades can pull in up to 5.28 gallons of air per second.

Why is it that my PC can run high-end games easily, but is unable to emulate Nintendo DS games smoothly?
|
You can think of the emulator as a live translator. The DS game tells the emulator what to do, and because it's supposed to run on Nintendo hardware, the language it speaks is Nintendo specific. The emulator then has to put the instruction into terms that the PC can understand. This works fine if two languages are reasonably similar, but if you're trying to translate 'Schadenfreude' from German to English for example, there's no direct equivalent, so what you have to use instead is a rather long-winded desciption of what the word means. That way, one German word may turn into 50 English words. The same thing happens with emulators for dissimilar hardware. If there's no direct equivalent for a certain instruction, you have to use a workaround that yields the same basic result, but that workaround may take 50 or 500 different instructions. That's why emulation tends to be slow. The computer running the emulator may very well be 20 times faster than the original machine, but that doesn't mean much if it has to perform 200 steps to do the same thing that the original hardware can do in one step.

Why does fusion release energy?
|
Ummm, the energy released during fission is not, like, stored inside the nucleus of the atom, but it's actually the nuclear mass, which gets transformed into energy. This is called as "mass defect", and the same is the cause of release of energy during fusion .i. e. When two nuclei fuse under pressure some of the mass gets transformed into energyFusion releases energy when you fuse certain elements, and consumes energy when you fuse others. Every nucleus has a quantity called it's "binding energy", which is generally speaking the quantity of energy that would be released were you to bring all of the individual protons and neutrons together from infinite distance to build the nucleus. You can also assign a binding energy per nucleon. For light particles, like hydrogen or helium, with few nuclear interactions, this binding energy per nucleon is fairly low. Therefore, if you fused two deuterium nuclei together to make He, the product would have a greater binding energy per nucleon, and a net output of energy result. However, were you to do this with heavy elements , the binding energy per nucleon **drops** as you go higher, meaning you have to add additional energy to fuse the nuclei. The reverse process, fission, will release energy for these heavy nuclei. As to why this is, keep in mind that nuclei are held together by the strong force, a very short range interaction between particles with color charge. Small nuclei with very few nucleons don't have many opportunities for interaction, so they have a relatively low binding energy. Similarly, large nuclei can become so large that particles on opposite sides of the nuclei interact much more weakly with one another.

A very long time ago automotive electrical systems were in fact 6 Volts. Someone figured out that if the voltage was doubled the current would be halved and thus allowing smaller Gage wire to be used and a significant cost savings to be realized. Wait for it it won't be too much longer and we will be seeing 24 Volt systems to become the next standard.

Why are a bunch of boards closed to the public like /r gaming?
|
Reddit fired Victoria, the wonderful lady who coordinated a lot of the celebrity AMAs in /r/iama. iama and a few other subs are going down because this actually really fucks the way they operate. The others are going down in a show of solidarity.

How do we know that all snowflakes are different?
|
We really don't know. We base it on simple math and probability. It's so unlikely that we can say with high probability that every one of them is different.this is a similar question to asking, "how do we know every human ever has different fingerprints?" it is impossible to know for sure, but based on the random way water crystallizes when it freezes and the seemingly infinite ways that it can spread in three dimensions , we can assume that no two snowflakes are exactly the same.I remember watching a short documentary about this in school when I was very young. Some guy took a bunch of snowflakes, put them under a microscope, and took pictures of them. He did end up finding a few that were pretty much ecactly the same. I guess my teacher made us watch that to remind us that we aren't special

Why do grocery stores let you do self-checkout when that makes it so easy to steal?
|
Grocery stores keep track of the estimated cost of theft. They have almost certainly determined that the cost savings associated with self-checkout are greater than any incremental increase in the cost of theft.* they usually have someone there monitoring against theft* they usually only allow a smaller amount of items in self checkout, you aren't going to be able to steal a cartful* the amount you can get away with stealing is small compared with the punishment you are risking* the money they lose to increased theft is smaller than cost of the extra checkers

I understand why someone wouldn't want the government to ban gun sales, but what reasons do they have to be against stronger background checks prior to a purchase of a gun?
|
If the government tracks gun sales, they would by extension track gun ownership . People are uncomfortable with the government knowing what guns they ownIts more complicated than that. If I want to let my good friend or family member borrow my hunting rifle why should we both have to go to a gun store, pay $50 and wait a week before doing so? Not to mention repeating the process when he wants to give the rifle back to me.Because some people don't trust the government to make better decisions than themselves.

Why are we not harnessing solar energy from unpopulated areas?
|
Cost. Plus the further away the power generation is, the more is lost in transferring that power over long distances . Plus, solar panels can't run 100% of the time, so require a ton of batteries, and both the solar panels and the batteries require a lot of maintenance. There are actually many areas of the world where investments in solar energy are being done, but it isn't really a solution everywhere. Many places are cloudy often enough to make solar power only a mediocre long-term solution over other sources of power, with a larger upfront cost.Cost deffinatly has to be the biggest reason, solar energy is more expensive than traditional coal or fossil feuls. Mostly dues to the cost of constru ting and maintaining the panels

What exactly was FDR's New Deal, and what did it do for the US?
|
The New Deal was a response to the problems created by the Great Depression. To put it simply, a lot of government agencies and programs were created. Some of the more controversial programs allowed for labor unions, regulations on child labor, maximum hour laws, and minimum wage laws. At the time, these were controversial - there was a very different conception then of the relation between employer and employee and the role of the federal government and the state governments. The Supreme Court struck a lot of these laws down until they eventually started upholding them . Many credit the huge growth of Federal Government to FDR and his New Deal, to some this is good, and to some this is bad. It is often praised for an example of the government passing legislation to help the country. Many think that the Great Depression would have been way worse without the New Deal.

Why is the Wilhelm scream still used?
|
It's an inside joke among the audio mixing people in the business. They put it in every movie, tv show, cartoon, and commercial where it's even remotely appropriate just for laughs.

Why is it a problem that Cuba is communist?
|
The issue is not that they were communist, it is that they were allies with the USSR and are allies with Russia. Russia is still our biggest enemy and we are still having proxy wars against them. The Cold War officially ended when the USSR collapsed, but in most practical purposes it is still goingBack then or now? Back then, assuming you mean problem as in problem for the US, the answer was less that they were communist and more that they were allied with the Soviet Union, which as you know was a big rival of the US.

Why do people hold their hands "palm up" when it is raining?
|
The palm of your hand is more sensative than the backSo we are just reaching to see what it feels like, how hard is it? what temperature is it? we do the same thing when testing the water in our shower, or in a sink.

can the body repair a rupture of a spinal disk?
|
So I ruptured the disk in my neck. The doctor explained it like this: The disk is like a krispy Kreme doughnut. When it ruptures the jam inside spills out. It could split on the inside or on the outside. On the outside is not such a problem. However on the inside it can directly apply pressure to the nerves it surrounds. After a while this jam can 'dry' out and can retract back inside. This is painful for obvious reasons. Now the non ELI5 bit. See a doctor if you can. If you loose feeling or get pins and needles in a limb see one immediately. This is, according to my doctor 'really bad'. Now I just had extreme pain, we are talking screaming and being taken away in an ambulance high on ketamine bad. The 'jam' was only 2.6mm according to the scans. It has healed but is weaker and occasionally happens again to a less serious degree each time.

How does your computer removes files when you empty your *local trash* ?
|
Computer files aren't really ever "Removed" or "deleted", they are just marked to be overwritten on your hdd. When you first delete something it is moved into the recycle or trash bin. Its kinda like purgatory for files; they're not marked to be overwritten, yet also cant be used unless restored. Once you empty your trash bin your computer officially marks the space the file is occupying as usable; the next time you install or download something it will be written on top of the deleted files, effectively destroying them. Its worth noting that just because you deleted a file doent mean its gone, if it hasn't been overwritten its still there and can be restored using the right programYour operating system doesn't really delete the files. It just tells the operating system that you can overwrite the area the files were previously. This information about "free space" is stored in an allocation table that is created when you format your hard drive. You can only truly delete files by overwriting the data with 0000s or something else sanitary.A regular *empty trash* command doesn't remove the files. It just erases their locations from the directory, and marks the space they are in as available to be written over. If you need them *really gone*, you have to do the secure delete that writes ones and zeros over the space where the files are on the disc.

Why does standing in one place for twenty minutes make my feet hurt more than walking for an hour?
|
Standing up straight still requires your muscles to do work. But it's "static\' work which means it's the exact same muscles doing the exact same thing over and over again *without being given a chance to relax and recover* When you are walking around you are using a series of difference muscles. Even though there may only be a short gap between when each muscle gets used it's still enough to spread the load and give your muscles time to recoverWhen you stand still, you keep constant pressure on certain spots of your feet with no relief. When you walk, even if you put pressure on the same points, it still gets some relief from the pressure, blood is able to flow to that spot, etc. Plus, the act of moving also encourages your blood to flow back to your heart, and standing still allows gravity to work on it more, so it pools a little, leading to some swellingSorry, super late to this post. From a more medical point of view, when you stand still, gravity causes blood to pool in your legs in the venous system . This pooling causes metabolites to accumulate such as lactic acid and substance P and this accumulation leads to pain. Now for walking. When you walk, you essentially have to utilize your leg muscles, especially the calf muscles. The calf muscles contract and this applies pressure on the veins which counteracts blood stasis by helping pump blood back to the heart. Hope my answer was useful.

why are some banks able to give different rates on things, ie. a higher yield percentage on savings accounts, as opposed to others?
|
Like any business, it's competition. There are certainly costs involved with running 1000's of branches that online banks don't have to deal with, so they do have some efficiencies they can pass along. But there are also concerns about online-only banks many consumers have, and higher rates are a way to entice more people to consider using them. Even if the expenses were equal, the online banks might be willing to forego profits today to grow their customer base, effectively using the higher rates as a marketing expense for customer acquisition.
