What happens when a ski lift breaks down? How does everyone get off safely?
Well when it happened to me, we just sat there annoyed until it was fixed. But a ski lift is essentially a giant conveyor belt, so there's probably a way to rotate it mechanically without power.
If all our cells renew themselves every 7 years, why do we appear to age over time?
Because the regrowth is not perfect, the body also needs to grow until its twenties, and because wrinkles are not affected by replacement. A wrinkle is like if you squished a cloth a bunch of times, it would have wrinkles and replacing all the individual threads of the cloth would NOT make the wrinkle go away, because everything had already been bent into shapeThere's a couple of reasons. One is that our bodies aren't entirely made up of cells. There's also extracellular material which is made from collagen and other proteins, it's job is essentially to hold everything together. Past the age of 20-ish our bodies begin to decrease the amount of extra-cellular protein they produce by approximately 1% every year. Over time this results in our skin becoming less elastic and more wrinkly. The other reason is that our cells only have a limited life span. There are "caps" on the end of our DNA called telomere's. Every time a cell replicates this telomere gets shorter. When the telomere has all but disappeared, the DNA begins to lose it's structure and the cell can no longer replicate accurately. Over our life time telomere's are constantly getting shorter and some cells are losing the ability to replicate.
Why do Dogs have a much shorter life expectancy than humans?
Why Humans Live Longer Than Dogs Being a veterinarian, I had been called to examine a ten-year-old Irish Wolfhound named Belker. The dog's owners, Ron, his wife, Lisa, and their little boy, Shane, were all very attached to Belker and they were hoping for a miracle. I examined Belker and found he was dying of cancer. I told the family there were no miracles left for Belker, and offered to perform the euthanasia procedure for the old dog in their home. As we made arrangements, Ron and Lisa told me they thought it would be good for the four-year-old Shane to observe the procedure. They felt as though Shane might learn something from the experience. The next day, I felt the familiar catch in my throat as Belker's family surrounded him. Shane seemed so calm, petting the old dog for the last time, that I wondered if he understood what was going on. Within a few minutes, Belker slipped peacefully away. The little boy seemed to accept Belker's transition without any difficulty or confusion. We sat together for a while after Belker's death, wondering aloud about the sad fact that animal lives are shorter than human lives. Shane, who had been listening quietly, piped up, "I know why." Startled, we all turned to him. What came out of his mouth next stunned me. I 'd never heard a more comforting explanation. He said, "People are born so that they can learn how to live a good life -- like loving everybody all the time and being nice, right?" The four-year-old continued, "Well, dogs already know how to do that, so they don't have to stay as long."Heart rate. You will see that the slower the heart rate of an animal is, the longer it live on average. Elephants, giant turtles, whales have long life. Dogs, birds, ants have short life.

It is your task to design a life of your choice and complete it to the best of your ability.
How is Judaism a religion and at the same time being a Jew, a race?
Judaism isn’t big on converting non-Jewish people, so the religion never really branched out beyond the ethnic group that started it. For the most part the only people who are Jewish are so because their parents were Jewish and so on and so forth, leaving most Jews being of one common ethnicity. Additionally, inter religious marriage was seen as pretty taboo for most of history, so you didn’t have a ton of Jews marrying outside of their religious group.
Can windfarms strategically placed in the middle of the USA stop tornadoes?
That is like asking if we put enough pennies on a railway track, could we stop a runaway train or if man had a harry enough chest, could it stop a bullet. There is so much energy in the weather system that anything we have or currently can do would barley be measurable if at all. Short answer, No. Long answer, Noooooooooooooooooooooooooooooooooooo.
Being fluent in more than one language, why sometimes you can't remember a word in your native language, but know it in the other(s)?
Imagine a bunch of boxes. Each box is a concept, not the thing itself or the word, but the idea of the thing. When you learn words, you put them into the corresponding boxes. The word "tree" goes into the box for the concept of a plant with a stem and leaves, the word "mother" goes into the box for the cincept of the being that gave birth to you and so on. When you then learn a second language, you put more words in the same boxes, so you then have both "tree" and "Baum" in the same box and "mother" and "Mutter" in the same box. Ideally, each word is "tagged" with the language it belongs to and when you want to express a concept in a language, you go to the box and look for the word tagged with that language. Depending on how tired/distracted/rushed you are, you look less carefully for the correct tag. Also, especially in people who speak more than one language daily, tags can get jumbled. This causes you to grab the wrong word and you have to make a conscious effort to look for the correct one.
Why do companies say "no purchase necessary" when they run contests?
So, in some parts of the United States, contests that require you to purchase something are considered a lottery, and lotteries are legally only allowed to be handled by the state. As such, they need to make it not a lottery, by allowing people to enter by sending a letter to the company instead of buying something. Now, most people don't write letters, but the option exists and thus they are legally covered.
What happens when both litigants in a lawsuit generally use the same lawyer or firm?
A single firm can't agree to represent both litigants in a lawsuit. When the second person tries to hire them, they have to say "sorry, there's a conflict of interests, you need to find another firm".As NOT a lawyer, that's conflict of interest and they wouldn't be able to handle both cases. There was an episode of the Sopranos where Tony's wife wanted to file for divorce. Tony paid all the law firms in the area a retainer, which forfeit them from taking on his wife as a client.
How is comet Oumuamua (C/2017 U1) able to come closer to the sun than most of the planets in our solar system, and escape without going into solar orbit?
It's going fast enough -- higher than *escape velocity* -- for its momentum to overpower gravity's pull.
Why does sleeping help you get better when you are sick?
When you are sleeping your body is able to put all it's energy into repairing you and healing in any manner. Including fighting stuff off.
How come when power resetting electronic devices such as a cable box or router, you are instructed to unplug the power and wait about fifteen seconds? why is the wait necessary?
Inside electronic devices there are things caused "capacitors." These devices take in the electricity and help make sure that it is released to the device at a steady stream. Fluctuating power is bad for sensitive electronics. When you pull the plug, or turn the device off, you are giving the capacitor time to empty the remaining power it stored insideThere may be capacitors in the device that hold a partial charge for a bit before the charge naturally dissipates. It is also to force people to actually unplug the thing and wait not just rapidly pop the plug in and out of the socket which could cause all sorts of problems.
The Beatles (John, Paul, George) began by playing guitar and bass. Later songs have John and Paul on piano. Who taught them?
Pauls dad played piano while he was growing up so he picked up some stuff from him. He also took piano lessons in the early 60's. John probably just picked it up over the years, once you know one instrument its a lot easier to learn another especially piano. You can make it sound good without mastering it
Why is cell phone service non-existent in basements or certain buildings?
Concrete can block cellphone signals. It is thick/dense enough to stop cell phone frequency waves from passing through it.
How is Zionism antithetical to Judaism?
Some Jews believe that the Jews are not allowed to have a homeland in Israel until the Messiah comes. This is the reason Jews don't believe Christ was the Messiah. The Messiah was supposed to establish a kingdom for the Jews to live in peace and prosperity. But Jesus didn't do that, so they're like "he couldn't have been the Messiah then."', "If I understand the question correctly, it boils down to the idea that God himself will return the Jewish people to their homeland. Effectively, God will one day intervene and create a Jewish homeland. As such, there are some who feel that humans pushing for Israel is against God's Will; they don't see the connection to human action as god's will, so they see it has being against Jewish teaching. At least, I think that was what you were asking.
ELI 5: How does reddit's voting algorithm work?
To explain it like you're actually 5. The posts on the frontpage is shown in order of newest to oldest, however each upvote makes it so a post is treated as newer by a certain amount, which is less and less for each upvote. A downvote is pretty much exactly the opposite of an upvote.
why are urinals not shaped to prevent splashback?
There are lots of options available that were designed to prevent splash back, they naturally cost more than those that weren't. Because the guy that pays to construct the building doesn't give a crap about your shoes, he buys the cheap ones and places them uncomfortably close to one another. This toilet has a fly sticker located at the best place for an average person to reduce splash back. _URL_0_
Why can't we send radioactive waste into space?
It is really expensive, and the risk of failure a bit too high. Rocket blows up in our atmosphere, radioactive waste everywhere!My guest would be either ethics or the cost to accelerate things out of orbit.
How do graveyards make money or sustain themselves after they are full?
It's pretty complicated and gross. Graves are turned over in some countries. After around 100 years, grave sites lower caskets and bury new bodies over them. In some countries rights are perpetual. _URL_0_
How do websites use images or trailers of movies in their articles and reviews if it infringes on copywrite laws?
[Fair use] allows for using copywritten material for "transformative" use. The extent of transformative is debated but generally includes things like parody and criticism without having to ask permission from whomever holds the copyright. It doesn't allow you to use the entire work, just parts that are relevant to whatever you're trying to communicate.
is hearing the last sense a human has before dying?
We don't have clear data on this since it's impossible to interview dead people. For example they may or may not keep a sense of touch, or of internal body sensations, slightly longer.
Why was Richard Nixon pardoned?
To put it very simply, president Ford said he wanted to put "this long national nightmare behind us" by pardoning Nixon. Basically he didn't want the country to get bogged down in all the trials and endless continuing investigations into Nixon and staff post-WH. However, many Americans wanted to see Nixon and his co-conspirators publically brought to justice for so betraying the trust of the American people. They believed the pardon to be a cop-out, especially since many of Nixon's staff had had to face the music.As a result, Ford handily lost the next election for this very reasonThere's a story that goes around that Ford carried with him a copy of the judgement from the court case [Burdick v. United States] for the rest of his life. The judge stated that a pardon is an "affirmative defence" - meaning the defendant basically says "Yes, I did it. But for whatever reason I shouldn't go to jail"
Why is the spine arched (in the lumbar area) instead of just being straight?
Rigid things crack and break under repeated impact. Flexible things bend, absorb, and stay intact. The bends in your spine work the same way as rubber tires on a car or the shock absorbers on bumps in the road when you're driving. If you had solid wheels and no shock absorbers then your car would absorb all the shocks of driving into its sold tires and solid metal parts and it would shatter into pieces very quickly. The same goes for your spine. It turns the energy of the repeated shocks of moving around in daily life into flex and movement in the spine instead of just rigidly taking the shocks and quickly cracking and breaking.
Why is being a lawyer drastically different from other professions?
It's not really unique -- doctors of all sorts have to go through a similar process. Basically what it comes down to is that they are jobs that require a great amount of trust from the customers -- doctors and lawyers are both in a position to *really* fuck over their customers without them realizing it. They go to school and are taught in a very intense manner, both because there is a lot to know, and also because it is very important that they understand it well, because it's their role to understand it so everyone doesn't have to.I think you need to specify what you mean further. In what way is it drastically different?
What is the importance of the 'Closed Circuit' part of Closed Circuit TV?
It means that the data/stream is kept internally in the system. If the internet goes down, you don't lose your connection, it doesn't require a wireless system that could be interfered with, and hacking requires physically wiring into the system or direct access to the controlling computer.
Cable TV speed vs. internet video
TV channels are like giving a speech to everyone. You talk once, and everyone hears the same thing. This is **broadcast**. The system is designed to send the same channels to everyone, at the same time, all the time. Your cable box just has to "listen." Internet videos today are like you talking to each person individually. The more people that want to hear your presentation, the busier you get. Broadcast is a one-way system, you can't reply, participate, or upload. The Internet was designed to allow individual connections. This is great since not everyone reads the same websites, or downloads the same files, and certainly not at the same time. There are some other reasons why Internet video is not as dependable. Cable systems have hundreds of physical channels, only a few are used for Internet access. Almost all are used to broadcast TV channels. So there's just less bandwidth available . Internet video companies have found solutions though. Traditional TV is compressed with MPEG-2, which became popular with DVDs. Current codecs such H.264/AVC and VC-1, are twice as efficient. An even newer standard, H.265/HEVC, will be double the efficiency again. Internet video companies use content delivery networks to have copies of videos closer to where they are watched, to reduce the redundancy effect of the same stuff being moved multiple times over the Internet. IPv6 will bring multicasting support to the Internet, which means the network itself will be able to broadcast information instead of everyone having a unique stream even if they are all watching the same videos at the same time . It has been estimated that Netflix is one-third of all consumer broadband downstream traffic. Of course, money is big factor. Most of the money is made through the traditional system. As movie/TV spending shifts to the Internet, more money will be spent to upgrade networks to improve capacity, fix technical issues, and generally make sure mainstream paid video service doesn't buffer.
Why was James Holmes, the 'Dark Night' movie shooter, declared 'mentally ill' and not 'legally insane' in court ?
Insanity is a legal term, not a psychological term. Insanity is simply an inability to distinguish between right and wrong and an inability to function within our society as a result of mental complications. If a killer knows they shouldn't kill but do it anyway, they understand this difference between right and wrong and can't be called insane. They still may be mentally ill. Mental illness is simply any pattern of neurological behavior causes distress/harm to the self or others. This is not to be confused with abnormal behavior, which is simply statistically deviant. For an example compare the behavior of collecting with the behavior of hoarding. Both behaviors are very similar, however a collection usually yields a positive impact on a persons life while hoarding yields a negative.
Why does everyone use danish cookie containers as sewing containers?
Yeah man, it starts with old ladies being the least wasteful people you will meet. So, they get these old lady cookies from other little old ladies in their social group- then reuse it for sewing stuff since the lid is just the perfect height for the thread spools. The small ones stand upright and the big spools lay on the side! When she gets too old to sew, she asks her daughter or another female, "do you want my sewing tin? My eyesight is too bad to thread a needle anymore". That's how the family keeps the habit going unconsciously, since they 've always seen the sewing stuff in a tin, and the buttons are always in a big button jar. I am the proud owner of a few passed down button jars and sewing tins from granny, mom, and aunts!', "It's hard to get through a year without being given at least one tin of those cookies, and they are too useful to just discard. Gotta use 'em for something, and they are a good size for a sewing box.BRB let me go ask my mom. Or my Grandma. Or my aunt. Just . hang on.
Why do imgur gif's have to slowly load the entire gif while playing, when sites like gfycat can load before playing?
The GIF format was originally designed for looping animation. It's not very good for videos; the normal video compression excludes a lot of information that is redundant between frames, but the GIF format can't do this. So GIF files used to show a video are excessively large and take a long time to load. Gyfcat does not display GIFs, but converts the uploaded GIFs to a proper video format and just plays that.
Watts, volts, and amps.
Sorry, but this one is one of the more frequently asked questions here. I highly recommend using the search bar to answer this one. It is being removed for that reason.
Why does reddit some times hide the scores of comments?
It prevents groupthink. We have a natural tendency to agree with our peers and are impressed by early success. If you see three comments all at +1 and then one comment at +3, you may subconsciously think "the one at +3 must have more merit since it's higher", so you're more likely to upvote it yourself. Hiding scores for the first hour or so dramatically reduces this form of groupthink and promotes comment success more based on merit than whatever the first person to read it thoughThis is to prevent the usual "hivemind" of reddit. For example, if you see a comment with +10 karma, you are probably going to upvote it.If you see a downvoted comment, you will probably downvote. If you don't see the score, you will give a neutral vote.It's something that can set by the mods To use Deimorz wording > The goal of this feature is to try to reduce the initial bandwagon/snowball voting, where if a comment gets a few initial downvotes it often continues going negative, or vice versa. By hiding the score for a while after posting, the bias of seeing how other people voted on the comment should be greatly reduced. [Link to announcement of this feature].
Why/how do actors choose their "stage names"?
Many reasons! Some pick their own, some are given one. * Avoiding confusion with someone else, sometimes per Screen Actors Guild rules. There was already a Diane Hall, so Diane Hall became Diane Keaton. * Hiding national/ethnic background, especially in the past. Margarita Cansino didn't want to be stuck with "exotic" roles, so she became Rita Hayworth. * Hiding family background. Francis Ford Coppola's nephew Nicolas didn't want people thinking he 'd only made it on his uncle's coattails, so he became Nicolas Cage. * Some names are odd or difficult to spell, or don't seem marketable. Archibald Leach was given the name Cary Grant, Marion Morrison was given the name John Wayne, Maurice Micklewhite chose Michael Caine. ', "In a few instances it's because the Screen Actors Guild requires its members to have unique working names. E.g. Michael Keaton's birth name is Michael Douglas but that name was already taken.Jamie Foxx actually chose his stage name because he noticed that female comics usually perform first so he chose an ambiguous name to perform earlier.In the old days it would be done by actors with foreign sounding names who didn't want to be thought of as foreign. Today it's usually just someone with a hard to pronounce or complex name
How is the price for commodities such as oil/gold determined?
Supply and demand is what is comes down to. During summer time, when travel is more common, people use more gas/oil. Since the supply is controlled and kept constant, and the demand increases, there is less extra supply to go around. Prices go up, because people are willing to pay more for the access to oil, since they want to travel. Gold works the same way. Limited supply; when stocks are wild and people just want a stable place to put their money, they buy gold, cause gold won't ever lose it's value. However, when tons of people start buying gold, there isn't very much extra gold to go around, so, for the sake of stability, people are willing to pay a little more for access to the gold. When stocks are doing really well, people take their money out of gold and buy stocks. While the amount of gold stays the same, there is now extra gold to go around, so the price drops.
Youtube's copyright policy on music.
If a video of your contains obvious music that belongs to someone else, it *might* get caught by Youtube's filters. Otherwise, Youtube doesn't care, until the intellectual property holder contacts them about your video. At that point the rights owner can choose to put ads on your video, the revenue from which will go to them, put one of those little ads with a link to the amazon or itunes music stores on your video, or have your video taken down completely. Music that you can put in your videos: unlicensed music, public domain music, music that you have bought the licenses to, and short enough samples that it's obvious you're referencing the music, not distributing it. You can find lots of free to use music online, just search for "royalty free music". Public Domain music is anything that had a copyright, but that copyright expired. In the United States , copyright lasts the life of the creator, plus 70 years, which is [absurdly long and destroying creativity so that big companies can make a buck]. So basically, if something was made by your great, great, great grandparents\' contemporaries, it's okay to use.
Taurine Manufacturing in energy drinks
You already answered your own question, testicles basically do what we do in the lab, they provide the right temperature, substrate, enzymes required to chemically alter a molecule. From animal sources would be time consuming , and you'd have to add some steps to isolate taurine from the rest of the biological material. The only difference is that the thing that caused the taurine to be formed is natural rather than because of us . To be fair, the amount of taurine required to actually have an effect is way higher than what's in energy drinks so the point is basically moot anyway, some preliminary studies suggest caffeine is the only cause . **TLDR: Taurine from bulls is in solution and means you need to isolate it , in the lab you just put in the reagents and form taurine. They use synthetic taurine in energy drinks.**
Why are car model years not displayed on the car itself?
Because people don't want to advertise how old their car is. It would therefore be detrimental to sales. I can tell you that I've seen examples where the model year was incorporated as part of the license plate. People absolutely *hated* it, and complained vehemently until that law was repealed.
Why is the flow on the discharge side of the fan much faster than on the suction side of a fan.
Its only because the air is concentrated at the discharge. You're pulling in the same volume as discharging.
What Twitter does with the extra 20 characters
On Twitter, you can have other people's tweets sent to your phone through text message. If the max was 160, you wouldn't be able to tell who sent the tweet because the tweet took up all the characters allowed in a text message. So basically, 20 characters for usernames, 140 for content.
if I check myself into a mental hospital, who takes care of the things like my job, my property, my bills, etc?
It's correct that you would need to make arrangements on your own or arrange for them to be arranged -- which really sucks because that's pretty freaking difficult to do when you're experiencing that kind of crisis. A few notes: - Your employer may offer something that in the states is called an Employee Assistance Program . They are typically programs paid for by your employer with employees who can walk you through most kind of crises and direct you to resources. - Also check whether you have a short-term or long-term disability plan through work. If so, it is usually treated like like a leave with your work. - Finally, maybe you're just asking hypothetically, but there are a lot of resources if you need someone to talk to right away, its not necessary to try and get through it alone. The national suicide & crisis hotline is 1-800-273-8255 and [here is a list of others], although I'm not sure how up to date it is.Normally, it does not. You could try to arrange a leave of absence with your employer. Sometimes states/countries have laws about medically necessary long term leave. Some do not. You should also pre arrange with your family to take care of your affairs. Normally you would sign some kind of document allowing them to do this. That or you just prepay all your bills. Basically you have to make your own arrangements before going in. Or your care givers need to make those arrangements.
. What is a quantum computer and what are the applications.
A quantum computer is like a normal computer, but instead of using 'bit's that can be either 0 or 1/on or off, they use a quantum mechanical object that can be both at the same time in a process called superposition. The object is called a quantum bit, or qubit. The effect of this is to be able to, in essence, run multiple computations on the same qubit using specially written algorithms. Quantum computers are no better for most things, but they are much faster at certain types of activities, like oracle operations, or perhaps most importantly, factorising large numbers . This last one is important because the best encryption strategy we have, the RSA key, is based entirely on the fact that computers take too long to find the prime factors of very large numbers. If a quantum computer can do this faster, then it can break the RSA and our encryption is no good anymore.
Why are street lights clear and bright white when they turn on, but then turn into that orange color we are all so familiar with?
Orange streetlamps are low-pressure [sodium-vapor lamps]. The clearer, pinker/whiter glow when it first turns on is the lamp heating the solid sodium inside. As the lamp heats up, the sodium vaporizes. The sodium vapor is what gives off the orange-ish light. Sodium vapor lamps are extremely energy-efficient, and they don't decrease in light output as they age. That's why they're frequently used as streetlights. You don't see them elsewhere because that orange color is really ugly.
Since nose hairs act as a filter for germs and bacteria, when you trim your nose hairs are you more susceptible to illnesses?
The relatively large hairs in the nose don't do much for bacteria and viruses. The large ones might be helpful for dust etc. but I'm not 100% on that. The 'hairs' that are important for protection against bacteria and viruses are the microscopic hairs , which line the rest of the respiratory tract. Smoking and other conditions that destroy the microscopic cilia certainly do contribute to a susceptibility to colds, bronchitis, etc.
Why do Sport drinks like Gatorade hydrate you with that much sodium in it?
The purpose of Gatorade is not to rehydrate you . It's main purpose is restore electrolyte balances . Professional atheletes sweat excessively, and when they do they lose both water and salt. Drinking just water doesn't replace the salts, Gatorade does.
Why do I sometimes get the feeling of a splash of water dripping on me when really there's nothing there?
There is something there. Me. Flicking water. At you. And you'll never catch me.
How are those scary clown pranks not illegal?
I didn't watch the entire video. I just scanned it. We're they dressed as clowns when they "impersonate policemen"? If so that's not a crime. Since no police officer would wear clown make up on the job. So it's clearly not a police officer. However if not then it's a crime. It's not illegal to dress as a clown and scare people. But they do risk being punched or even shot. Which has happened. It's childish and stupid but legal. At least in the US. Also someone could sue them if the scare was bad enoughIANAL: But I am not aware of any laws that prohibit one from dressing as a clown and going to a gas station.
Why are there still so many electronics devices like printers that give cryptic error codes instead of just a plain English explanation of what's wrong?
Two things, the first is complexity, devices with a tiny 16 character display really don't have much of an option to display a full error message and might not have the capability to store that text internally , error codes are a simple way to give the user a very condensed description, where they can look it up. Second, it's sometimes just the work and effort in displaying the error isn't worth the effort for the quantity of errors the developer wants. A good example of this is the way the C programming language works, there is one variable, errno which contains a single number, there is a large list of predefined errors, and a library can state that error simply by writing one number to one variable. This is extremely simple, ensures that almost anything can issue an error , and an error handler can simply check this periodically and display the easy to read error code. Sometimes you get numbers because developers don't really track their codes, and just put numbers in, it's enough for them to track it down, and while not really helpful to you, it's likely the real description of the problem wouldn't be helpful to you too.
why do browsers have to put from where did you acces to that website: (utm_source=chrome-ntp-icon)?
It's google analytics tracking code. The site you are visiting wants to track the source of the traffic. either that or you clicked on a link that uses this code - more common in newsletters tho.
Why do we wake up if we are falling in our dream?
The jolt of adrenaline that rushes through our body wakes us up. Falling or dying feels very real, and our brains and emotions work overtime. *It's that feeling of falling you get that jolts you awake. It snaps you out of a dream.* The "Kick". Most times, it feels like Inception. That feeling of falling or near death experiences always seems to occur when someone's trying to wake me up by calling my name or tugging my arm :)I actually don't always wake up after falling in a dream. During one dream I fell from the Eifel Tower and just sort of .laid there. A few others I 'd fall from buildings but, in the words of Jessica Jones, it was more like "graceful falling."
Does someone with stronger, bigger muscles have a greater resistance to pain than a skinny, scrawny person?
The 220 would be vastly more prone to injury and pain in this example due to weight. Imagine if at 110 he landed feet first with just an ankle sprain. Now add another 110 pounds and maybe that's a fractured tibia. In some examples, like when people take cannon balls to the gut, sure strong muscles are why they can do that. However there is no general rule for this. Nor does the additional muscles some how numb up your pain receptors.Pain is a result of the firing of nociceptors, which are neural receptors specifically made to respond to pain . Pain tolerance is a mixture of psychological factors and biological factors. Psychological factors include mantras such as "mind of over matter" which many athletes tell themselves to endure the lactic acid burn that occurs during extreme aerobic exercises. Biological factors would include less responsive nociceptors, less opioid release, and things of that nature ). So would muscle mass/weight have anything to do with pain tolerance? Overall, I would not make that generalization. There are too many other factors to consider when examining an individual's ability to withstand pain.
Why do political parties try to be opposites of each other instead of working together to solve problems?
It's much harder to get elected that way. If I'm running for office and you're not sure if you should vote for me, which sounds more convincing: "Hey, vote for me or the other guy, we'll each tackle these problems in our own way and arrive at a reasonable solution." "That other guy stands for everything you oppose and the only way to keep that maniac out of office is to pick me. Also, I believe in exactly what you want."', "Your question is based on all kinds of assumptions. First, political parties often do work together. Even in the US, levels of partisanship that we see today are a recent occurrence. Democrats and Republicans have worked together for centuries, and in countries where coalition government is the norm, parties work together constantly to achieve common goals. Second, no political party in a democratic political system can rightly be called the 'opposite' of the other. Parties have huge areas of agreement. Of course, they rarely talk about them, because they agree, but they're still there. However, there are some disagreements that parties just can't overcome. What responsibility do we have to our society? How important is collective security compared to personal liberty? I don't know if any amount of arguing can ever bring us to a conclusion on these questions, so naturally parties are going to take different stances.
How speeding was enforced before radar guns
Two lines were painted on the road at a measured distance and police would check the amount of time it took to pass both lines. Using that information they could figure out your speed. They would also get behind cars and pace them with their own speedometersIn South Africa, the police listen to the time in between the "thumps" as you cross the railway lines. They'll tell you that you were speeding because they heard a "thump!!. thump!!" and not a "thump thump.." ..although usually this argument will just go on and on until you slide out a sneaky \'20.
After a few deep breaths of cold air, why are my lungs so sensitive?
The purpose of your upper respiratory tract is to warm and moisturize air before it gets to your lungs because the cells lining the inside of the lungs are very sensitive to these conditions. If you're breathing really cold air then there isn't time for it to reach ideal temperatures, and it can irritate or damage the cells in your lungs, which may cause them to produce mucous or become inflamed, as in an asthmatic reaction.
How come 100% humidity doesn't mean that water takes up all of the air and we arent walking in swimming pools.
100% humidity doesn't mean the air is entirely water. It means that there is as much water vapor dissolved into the air as it will hold. Basically, it's the point where if you left a glass of water out no more of it would evaporate.100% humidity means the air is saturated with as much water as it can hold in vapor form, not that the air is 100% composed of water.
how do telescope cameras take long-exposure photos of extremely far away things? Wouldn't the rotation of the earth/ earth' orbit screw up the focus of the picture?
The aim of the telescopes is adjusted in real time to match the rotation of the planet, using electric motorsMost telescopes have a computer and motor for this purpose. You need to align the telescope first based position of the telescope and time and when that is complete you can basically tell the computer the coordinates of the sky you want to watch/photograph. Then the computer makes sure that the telescope is tracking the coordinates based on calculations of earth rotations, coordinates or even objects. Its pretty cool actually. You can tell it to track the moon and it will keep the moon completely center of your viewer.
Does Earth's core really keep on rotating? Why?
Earth's core rotates for the same reason the rest of Earth rotates, which is because of retained rotational momentum from its original formation. Also, if you heard about it from the movie The Core you should probably just forget it. That movie is horrendous from a scientific standpoint.
String Theory, why people like and don't agree with it
I won't get into trying to explain String Theory in five-year-old terms. That's probably better suited for someone else. But I can probably help with the second part of your question - Why some people like it - String theory aims to solve one of the biggest problems facing particle physics - how to reconcile quantum gravity and general relativity. If you 've ever heard the term "grand unified theory of everything" tossed around, string theory is one of the more famous contenders for this title. From a standpoint of physics, this is potentially a pretty big deal. An "understanding the secrets of the universe" kind of big deal. Why some people don't like it - A common theme among most criticisms is that string theory doesn't have much of a practical use in terms of making solid, testable new predictions with current technology, which is expected of any decent scientific theory. It's unlikely that any rigorous testing will be achievable any time within the near future. Many scientists also think that string theory also offers no real elegant solution for including quantum gravity within it's framework, which is a significant problem for a theory purporting to be a potential "theory of everything." Some people within the physics community also dislike the mathematical framework behind string theory, alleging that it is incoherent and unnecessarily complex.
How can the tone knobs on a guitar amp change the way a single frequency sounds
No. When you play a note on a guitar you are playing SO much more than one frequency. You are playing a FUNDAMENTAL frequency plus lots of quieter frequencies called "harmonics" or "overtones." The amplitudes of these frequencies are one of the main factors in determining that your guitar *actually sounds like a guitar*. When you change the bass, middle, and treble knobs on your amp, you're actually revaluing the amplitudes of these harmonics and your fundamental. This is an incredibly complex area of study that we actually don't fully understand yet. Sorry. Like you're five: When you play your guitar, you're actually playing more than one note at a time, even when you only hit one string! It's just that there's one main note that's a lot louder and a bunch of little notes that you have to train yourself to hear! Those little notes are one of the factors that determine why a clarinet sounds different from, say, a car horn! Every sound you hear has all those little notes, but the volume levels of WHICH little notes let us distinguish instruments! On a much less drastic level, every time you turn one of your tone knobs on the amp, you're adjusting the volume of some of those little notes. When you turn the treble knob up, you're making the higher pitched little notes louder! And when you turn the bass knob down, you're making the lower little notes quieter! That's why you have those knobs! And that's how they work. Remember, you're NOT just working with one frequency!
The difference between The Patriot Act and the Prism program.
The Patriot act is a bill that grants additional rights to congress and the president. The Prism program is a bunch of things the NSA seems to be able to do under that bill. Maybe. Some people think they have done illegal things, but plenty of people think it's a natural outcome of the patriot act.Prism is simply the NSA name for an operation. The Patriot Act authorizes it. The NSA has not broken the law. The Law could very well be unconstitutional.
Why would the Cleveland kidnapper plead not guilty when their is so much evidence against him?
Sometimes people plead not guilty by reasons of insanity. By that I mean he may attempt to argue he shouldn't be punished because he didn't have control of his actions. That seems pretty unlikely due to how normal he seemed most of the times, but it is an option that's used in situations like this. He also doesn't really have much to lose. Any plea deal will probably leave him in prison his whole life. The only thing he'd probably be guaranteed to avoid with a plea deal is a death sentence, but I'm not even sure that's possible if he goes to trial.If your only chance is one in a billion, you still take it. The odds that he can avoid life in prison are, to put it rather mildly, minuscule. That said, his chances are zero if he pleads guilty.

- What did the Glass-Steagall act do exactly, and why did its repeal contribute to the recession?
I think that "The Newsroom" did a really good EL5 year old job. [Olivia Munn]Basically it allowed for 2 different kind of banks to become one kind of bank. That one kind of bank had the ability to make riskier investments with money that is supposed to be relatively secure.
The strange jolt euphoria you occasionally get when certain things happen (Friday afternoon, driving through nice weather, etc.)
When things happen, i.e. Friday afternoon after work, this is perceived as a reward due to culture . So, this perceived good activates the brain to release dopamine. Dopamine is a compound, a neurotransmitter, that acts as a messenger. This messenger activates the reward system, which reinforces the connection between Friday and good or seeing friend and good. Release of dopamine plays a role in drug addiction, which is a reason why certain drugs make you feel good.Sorry i don't have an explanation for you but sometimes i have the same feeling and also wonder why i get this feeling just now
Why are there no hooved predators?
Soft padded paws are a feature of most mammalian predators because it provides for stealth when hunting. Hoves do not offer the advantage of this adaptation. But do not think that hooved creatures are not dangerous-they will fuck you up. A bison will clean your clock and trample you to death. A wild boar will chase you down, root you and tear you to piecesHooves are absolutely shithouse for grabbing onto things, they are geared towards speed.
How do internet providers make the internet they sell?
They don't. ISPs give you **access** to the internet by running wiring between your house/apartment to a CO . The CO serves as a hub for traffic, allowing lots of small connections to be joined and sent through larger connections . All these connections allow you to contact different people or servers . To get to servers on another continent, there are undersea cables as well as satellites that can send information around the world quickly and efficiently.
How can bugs fly in through the smallest crack in a window, but can't leave through an open door? (Or choose not to?)
Well, it's the one bug out of thousands that made it into your house by accident, but only one out of one that you want to get out as quick as possible. ;-)", 'They follow smells coming out from your house through the cracks. Once inside, there are no strong enough outside smells that can lead them outBugs that make it into your house through a small crack usually do so accidentally during their daily activities , or they enter deliberately to escape temperature extremes. Once they're inside your home, they simply are not smart enough to realize that there the environment on the other side of the open door is any more or less suitable than the one inside your house. Insects that wander in at night through a small crack are attracted to the lights on inside your home. This behavior is called "phototropism", and is a very powerful influence on their behavior. The only way to attract them back outside would be to turn all the lights in your house off, and turn on a very bright light outside your homeFlies are attracted to light. If you you want a fly to leave a room, just turn off the light in that room and open the door. Make sure the light is on in the hallway of the room door you are opening. The fly will leave the dark room to go to the light', "It would be a combination of confirmation bias and the fact that outside during the day is usually hotter than inside so the pressure out there is higher than inside Also it has no reason to leave
In the United States you can serve in the military at age 18, but you need to be 21 to consume alcohol. Why is that?
The more we learn about brain development the more we understand that a young person's mental development isn't finished until at least their early 20's . It is fair to say that we probably cannot assess risks clearly when we are 18 - so you are right to raise the point - we should probably raise the enlistment age to more closely align with what we now know about brain development.
Why do a lot of government entities and other companies insist on using Internet Explorer over other browsers such as Chrome or Firefox saying that IE is more secure? Is there any truth to this?
Usually requiring IE isn't by choice. in my experience it is typically because the business have spent a ton of money on an IT system that depends on some IE specific feature, like ActiveX for example. In many cases the business might even have two browsers installed on all their systems, one for their expensive legacy system they can't afford to replace and one for regular internet.
Why can't you scream loud enough to hurt your own ears?
Generally, nobody can scream loud enough to hurt your ears. There simply isn't enough power generated by your lungs in a single scream to do it. Sound is merely a type of pressure wave that your ear is able to sense, decode and turn it into something you understand. Sound is measured through a scale measured in something called Decibels. The decibel scale is logarithmic. This means that unlike a linear scale, 10 decibels is actually much more loud than 5 decibels rather than just being twice as loud. Because sound is a pressure wave, the stronger the sound, the stronger the pressure wave and vice versa. At some point the pressure wave becomes strong enough you feel it as an actual physical force in other parts of your body. Humans scream at about 80 decibels, the loudest scream recorded was 129 decibels. Whoever did that scream would have to be screaming for a good long time in your ear before gradual ear damage occurred through prolonged exposure. Anything over 140 decibels will cause immediate damage to your ears, particularly if sustained. It's also considered painful. The limit of true soundwaves is regarded to be around 200 decibels. Anything else above this would be actual physical force acting on you rather than a sound you could hear. It would likely also kill you as the pressure wave ripped you apart. To give you an idea of what 140 decibels is like, standing next to a jet turbine running at full speed would be about comparable. It would hurt greatly and permanently. At 155 decibels, your eyeballs would be vibrating. The nuclear bombs dropped on Japan had a force of around 245 decibels. Because the decibel scale is logarithmic, the increase in power as you rise through the decibel scale is incredible. To the extent that while 140 decibels is enough to damage your hearing permanently, 700 decibels is enough to wipe out earth, and 1000 decibels will rip apart the observable universe.
why can i be tired all day long, only to get home and into bed but then suddenly be wide awake when i lay down?

Why can't/wouldn't a medical dispensary be able to switch freely to become a recreational one?
Supply and demand and you need to put together a whole board of regulators and you need to grow a shit ton of weed. Also why would you want to take away the cannabis that the medical people need when you just wanna smoke a jay for recreational purposes.The same reason a pharmacy can't just become a bar. The laws, once they are finalized, involve a bunch of different regulators and tax offices. It's not clear that the pharmacy+bar has economic advantages to two separate businesses.
How does the popcorn button on the microwave work?
I recently protested the popcorn button against my girlfriend and my mother's wishes. I set the timer to the recommended time on the bag and burnt the shit out of the last bag.
What is happening during the time a beverage is being aged?
It really depends on the beverage. There are actually multiple different methods. For the most part, that means keeping it in a wood cask/barrel in a cool, dark, dry place for a long time. However, sometimes it is just kept in it's own bottle instead and aged that way. For example, some types of beer are brewed to get better with age or actually have active yeast in them which helps to further ferment the beer. In those specific instance, you just want to shield them from light in order to keep the photosensitive yeast from dying before the aging process can complete. In the case of yeast additives, the yeast continues to eat certain sugars to produce a different taste. With whiskey and scotch, they typically are aged in oak barrels, though one can use charred oak in a mason jar at home to do kind of the same thing. The whiskey/scotch will then "mellow out" and take on the oak flavor of the barrel as well as change chemically. Finally, certain kinds of wine are aged by essentially placing them in a cool, dark cellar. Only some wine will tolerate this and in these instances, the length of time to age properly is hotly contested and often very difficult. Even insofar as that some wines actually undergo a period often likened to adolescence in teens in which the wine gets stuck in an aging "rut." Younger wine has more tannins and the longer you age the wine out, the more the tannins change their chemical structure.
How can vision decrease unequally in our eyes?
What you are referring to is termed [Anisometropia]. The reasons for it are poorly understood, but there is some [evidence that one's dominant eye is often the one which needs more "correction," or has more refractive errors] than the non-dominant eye. [The Miles Test] is a simple, easy test to self-administer to determine eye dominance. It was true for me that I am left-eye dominant and my astigmatism and myopia were more severe in my dominant eye. A small percentage of the population is neither right- or left-eye dominant. Myopia , hyperopia and astigmatism ) [are genetically linked and research also indicates that how we use our eyes can be factors as well.]. [Presbyopia] is almost universal and is a direct result of aging and the loss of the lens\' ability to adjust for near-vision.

What is the definition of a lack of empathy?
The inability to understand someone else’s emotions and feelings from their perspective. Eg, if you were obese and I called you fat and it hurt your feelings. If I lacked empathy I genuinely wouldn’t understand why it upset you. Which is different from me understanding why it would upset you and calling you fat anyway.
Why was NASA based in Houston, Texas rather than any other of the 49 states of America?
The site required access to water transportation by large barges, a moderate climate, availability of all-weather commercial jet service, a well established industrial complex with supporting technical facilities and labor, close proximity to a culturally attractive community in the vicinity of an institution of higher education, a strong electric utility and water supply, at least 1000 acres of land, and certain specified cost parameters. Note that MSC was not just Mission Control. It was also to be NASA's manned spacecraft engineering center, so proximity to a large metro area and higher education facilities was considered essential to attracting staff. The Cape simply could not compete on that level back then. Remember that Disney World wasn't opened until 1971 and back in 1961 Orlando was a sleepy orange-farm community. The closest real cities to the Cape back then were Miami and Tampa. The decision by Humble Oil to donate the future MSC site to Rice University, which then made it available to NASA for free, also helped put Houston in the lead.
Why is horse racing such a tossup?
They are set up that way. Track stewards assign weights to horses to even out the odds. A very good horse must carry more weight. The less weight the faster the horse runs. More weight also means more injuries. The horse's trainer weighs all of these factors when choosing what races to enter. The goal is to win every race. So showing off how fast a horse is at the beginning of the season will result in more weight being added early and reduce the chance of winning later. It will also increase the chance of injury. Even a strain will slow a horse.
What's the difference between .com, .net, etc?
These .com, .net etc are top-level domains. In the beginning, the different top-level domains were used for different groups of people: COMmercial entities. US-based EDUcation. NETwork prodivders. US-base GOVernment. Not for profit ORGanistaion. US-based MILitary machines. INTernational organisations. And that was enough. However, the Internet grew and more and more countries got connected. Country-level domains were invented and you got .NL for The Netherlands, .AU for Australia, .US for the USA and .JP for Japan. Some of them used a similar system, for example ._URL_2_, ._URL_3_, . _URL_1_, _URL_0_. And some didn't and put everything came under their country-level domain. Even more, the Internet grew and more and more different groups of people came online: Individuals. General communities. Email providers. There weren't enough different top-level domains to accommodate everybody and the nearly everything globally got put under .com at the end. These days, there are some new top-level domains which can be used by various groups of people, for example .mobi for mobile phone operators, .aero for aviation related companies. Unlike the .net, .org and .com mess where everybody and their dog can register whatever they want, some of these new top-level domains have restrictions on who can register there, giving it a little bit more credibility.
how is it that waterfalls freeze while falling?
It's not the entire waterfall that freezes. It's a little at a time. The rocks below it, where water sits for a few moments, get cold enough and the water freezes. The water dripping from the top gets cold enough as well, and a little bit of water freezes there. Anywhere along the entire length where water sits for a moment, it will freeze. It's a drop here and a drop there. But then a drop falls on a bit that's already frozen, and freezes. And slowly it builds up until you have a column of ice. This typically happens while the river above and below is slowly freezing, but the river, being a body of water, takes longer to freeze and thus allows the frozen waterfall to build up before the supply of water to it stops.
What is the difference between a brownout and a blackout?
In a brownout, there's not enough power to maintain normal usage levels, but it's not completely off. You generally see things like flickering / dimming lights, reduced power to buildings, surge protectors going nuts, that sort of thing. In a blackout, the power goes completely dead. E: Wow, that was unexpected, but very much appreciated!
How did no one notice that tens of millions of cars were not meeting their emissions standards until now?
They were meeting their emission standards. That's the whole scam. I assume you're asking about the VW situation going on now. The software that runs in the computer that controls the engine and emission control systems was written to detect when the emission tests were being performed and *only while the tests were being performed*, to reduce the car's emissions. During the periods of emissions testing, when the computer put the car into low emissions mode, the performance of the vehicle, mileage, acceleration, etc., went way down. When the software did not detect that an emissions test was being performed the computer boosted performance and emissions went through the roof. This meant that when they were doing emissions testing they got great emissions results and when they were separately doing performance testing they got great performance results. They advertised both the emissions and performance results and people expected, reasonably, that the configuration of the vehicle was the same in both tests which it was not.
Why do we say 'Boo!' when trying to scare someone?
The B is [plosive], which is a sudden sound - and that suddenness is potentially more surprising. And compared to a few other plosives , it's easy to say loudly - and that sudden and unexpected loudness will more likely shock and scare someone, in the same way that a sudden, unexpected, and loud bang or crashing sound might.
I am constantly hearing about how adrenaline allows people to complete incredible physical feats. So why is it that I've never heard of adrenaline being abused in sports?
If you give someone a straight shot of adrenaline, you would immediately notice it. They would not be able to sit still. Adrenaline is typically used only in serious medical conditions, often emergencies, like heart stoppage. These factors make it difficult to abuse for sports, and it can put a dangerous strain on your heart if you are constantly shooting up with it.Performance enhancing drugs generally build your body up in the months before competition, not give you a boost the day before, because that's a less obvious change. It's like slowly replacing parts in a car as opposed to putting megafuel in it.
how my phone captured this picture right as it was dying and made it look like this
The interesting thing about that image is that it's two versions of the same photo -- were you taking an HDR photo? You have two different exposure settings, one slightly underexposed and one slightly overexposed. The software then combines the two images for a large dynamic range: the slightly overexposed version ensures you have some detail in the shadows, while the slightly underexposed version ensures you don't get large areas of bright white. That gives you a much more even, detailed image. Clearly, the camera's software crashed while it was processing the image. The two different versions haven't been combined yet; also, the blue channel is missing. The colour in digital photographs comes in three channels: red, green and blue, corresponding to the familiar three additive primary colours. It looks as if your image has all the reds and greens, but none of the blues: all the parts of the image that are white or light blue -- the sky, for example -- appear magenta, but the dark green of some of the vegetation is showing up well. I'd guess, then, that the software crashed before the blue channel was processed.
At what point did organisms become gendered?
The 'when' question was already answered, do I'll answer the one about the benefits. It allows for greater genetic diversity. When you reproduce asexually, the offspring only receives your DNA making it more likely to get sick . When you reproduce sexually, the chance of a genetic defect is much lower. I have no idea why there are two genders though.Are you asking about when sexual reproduction first occurred? Sex and gender are two different things. Anyways, sexual reproduction is thought to have first occurred around 1.2 billion years ago. The first organism thought to have developed sexual reproduction was a eukaryote. As to the benefits and purposes I will leave that to someone more knowledgeableNo idea. In the thread so I get the answer. Thanks in advance.
If everyone I know hates pop music, how does it get so popular?
You tend to hang out with people who share views similar to your own so your sample is skewed. Either that or you don't know enough people. ;)", 'Well,everyone I know voted for John Kerry in 2004 and look what happened. Everyone you know does not equal the majority of the buying publicEveryone you know != everyone in the world', "Most people like pop music. Some people think it makes them cool or badass to say they don't like it, whether they really don't or not. Kind of like how Bud Light sells like a champion but people either won't admit to drinking it or act like they are too special to drink such a plain beer.
What determines the power of an engine?
HP is unsurprisingly a unit of power which is the amount of energy delivered over a time. So when comparing two different engines you would pick one time period that is the same for both engines and measure how much energy over the time period the engine produces. |hey, let's make an engine with EXACTLY 218HP" or do they just design a -more or less- powerful engine and then checked the HP it can provide? You can more or less design an engine to produce x power. But there is more to the performance than just the power. You can get a huge amount of power but if the engine is poorly designed it won't be translated into motion or electricity or whatever the engine is for as well as it could beThe engineers are given a goal, e.g. "At least *x* HP with *y* MPG at *z* RPM" constrained by what the vehicle it's going into will be used for and how much it will potentially cost to mass-produce. Using existing knowledge of metallurgy, mechanics, chemistry, electrical distribution, etc, they can start with a baseline for the number of cylinders, size of the cylinders , computer-control of the fuel injectors, and even the materials used to make the engine. So, that 215HP engine design may end up being 218HP when they get the prototype on the dynoIn the engine, fuel is burnt in cylinders to cause explosions that drive pistons. The volume of those cylinders, how many cylinders there are, and how often they are fired determines the power output of the engine.
what (specifically) would happen to a house-sized treehouse as the tree grew? Would it be possible to live safely for many years (20+) in a large treehouse?
Trees can grow quite big. A few species ) are big enough to support a house. There are more risks than structure tho. You would have to take great care of the tree so it stays healthy If you started with a small tree, it would likely split whatever bindings you used to keep your house in place as it grew to its mature size. However, if you started with a mature tree of the right species you might find it surprisingly livable. There is a [hotel in Kenya] which was for about twenty years actually in a 300 year old fig tree, and it was considered safe and secure enough to house guests and hunt from, until some vandals with an axe to grind set fire to it.
If flushing the toilet wastes a lot of water, why don't we pee in the sink?
My brother-in-law is a builder. A few months after one of his jobs he was accused of installing a faulty sink. It was not draining properly. On investigation it turned out that the husband had been habitually pissing in the bathroom sink and had blocked the pipe with crusty pissy mineral build up. Don't habitually pee in the sink unless you have urinal cakes in there. The minerals in your piss will eventually block the u-bend.You'll have some uncomfortable questions to answer when the plumber comes and sees the depost crusted round the inside of the pipes.Another solution. In Japan, I think, I saw recently they had invented a wash sink that drains to a urinal basin. Also someone invented a way to harness electricity from the spiraling in the toilet flush. Every little bit helps.Peeing when you are having a shower is always a good idea if you're trying to cut down on that water usage.
Why are most circuit boards green?
It's the natural color of the epoxy. No other reason, really, and since no one spends a lot of time looking at them, they don't dye them unless requested by the buyer.
Why are VR games so much more difficult to make and why do they require so much more processing power?
> Is having those two corresponding viewpoints active simultaneously much different than split-screen on a FPS where each player has a different view? Not hugely different in principle but significantly in execution. First, your average console peasant is used to their game being presented at about 30 fps and somewhat distant on a television which takes up a relatively narrow field of view. Even 1080p televisions then cut that in half for a split screen. PC players prefer a 60 fps standard and also they tend to sit closer to their monitors which means they take up more of their field of view. This means games designed for PC will have wider fields of view to avoid nausea which results in more things on screen to render. The result is significantly more than twice the required rendering horsepower. VR is even more of a challenge. As the view for each eye takes up the entire field of view it needs to be a reasonable resolution in its own right, not half of 1080p, and of course the field of view for that camera needs to be extremely wide. In addition to avoid nausea you want to shoot for at least 90 fps which means even greater demand on hardware. Now do it twice over from slightly different viewpoints without stutter or delay!
Why does the IRS send tax return checks to people when there is so much fraud? Isn't there a more secure way?
You have it backwards. The IRS does allow direct deposit of refunds. And most of the return fraud that happens is through direct deposit, not through physical paper checks. Now if they sent it to the employer, that could help cut down on fraud somewhat, but the fraudsters would just claim to be self employed and so not have an employer , and the employers would probably not like doing the extra work, nor the taxpayer the extra time it would take. Nor would I care for my employer to know what my tax refund is if that is not necessary.
Why does every material tell me its origins (ex: Made in China) and why do I give a shit?
The easy answer is that it's US Law to name where the product is from. We don't trade with certain countries so if a product says it's from some country we don't trade with, it could be a counterfeit/illegal. Also from the countries perspective, they obviously want people to know where it came from for obvious reasons. And lastly, you give a shit if well if you actually care where it came from. Some people like to support the US economy and by items made in USA. Some people want to buy products as cheap as they can, so they are drawn to China.
Why do all men and women in old radio/tv recordings have "that" voice?
The neutral radio voice was a requirement in Hollywood for along time in order to not alienate some audiences. I speak neutral English and can get a job on any radio station in the US. I have friends from the south, the north east and along the Canadian border who can only speak there with out getting laughed at. For example: They drive a cah while I drive a car.I'm about 6 feet tall not aboot 6 feet tah.
Why do pens not work on certain surfaces, but after scribbling on another surface and getting the pen to write, it works on the original surface?
The ball at the tip of most pens is self lubricating with the ink. If left uncapped long enough, the ink will dry out and the ball is effectively glued in place. If the ball can't rotate, fresh new ink can't get by. On a thin paper on a hard surface, or a smooth surface aka "flat" only a small part of the surface is making contact with the ball. To get a stuck ball moving again we need more friction. A few sheets in your notebook has enough spring in them to deform around, and touch the sides of the ball, imparting more friction thereby breaking the stuck ink, fresh ink comes out, lubricates the ball and everything writes off into the sunset.
How is a population of 30 animals not automatically extinct from inbreeding?
Inbreeding does not always impact fertility. While it is bad for the genetics of a species careful husbandry of the breeding process can keep the genetics diverse enough to return to a functional population. Remember that genetically speaking all of the members of a species are related *a little bit*, including humans. Inbreeding creates increased risks, but it takes generations of dedicated inbreeding to really badly affect a species. With humans guiding the process and keeping family lineage records we can mitigate some of that and save the speciesThere is no magic number, below which a population is no longer viable. It is about what degree of intervention will be required to sustain it. In the harsh wild where survival is a struggle and you breed with whomever you can find, any drop in genetic quality can lead to extinction, so larger numbers are required. In a captive breed situation, where survival is easy and breeding partners can be specifically selected and screened, you can get away with much smaller numbers.
How Country A arrests a person residing in Country B
Alright, like you're 5. You've got a next door neighbor called Billy. You play together all the time, but like all kids, if left for too long you start annoying each other. Anyway one day you kick Billy in the balls. He cries, and you get scared and run home quick smart. A short while later Billy's mum knocks on the door. Your dad answers. Your dad likes Billy's family. Maybe he borrows their lawn mower occasionally, maybe he went to school with Billy's dad, or maybe he's shagging Billy's mum and doesn't want anyone to know. So your dad tells you that you have to go over and say you're sorry. And give Billy your favourite toy. He sells you out. But what if your mum answered the door? Your mum fucking hates Billy's parents. Maybe the lawn mower does more harm than good, maybe Billy's mum picked on her in school, or maybe she doesn't get laid enough and has an idea why. SHE tells Billy's mum to fuck off, and slams the door. Hooray, you're saved! Your parents represent different countries; Billy's family represents a single country. You are a citizen of either of your parents' countries, depending on who answers the door. Edit: improvements.there are extradition treaties in place that say if a person commits a crime in Country A and flees to Country B, then Country B will send him back to Country A for a trial. but not all countries do this, which is why if you kill someone one the US, you should get yourself to Venezuela as fast as you can.
...why are "mobile links" a problem on Reddit?
mobile links are links which refer to sites that have a layout optimized for mobile devices. One example would be _URL_0_. This layout often looks very bad on desktop computers and often has a simplified layout and therefore is not appreciated.Because if you post a mobile link, desktop users get sent to the mobile version, which doesn't look good on a desktop. If you post the normal link, mobile users will normally be redirected to the mobile version automatically.
Tesla's Dynamic Theory of Gravity
No one has a damn clue what Tesla was talking about. He died before publishing anything, and his notes were never made public after the US government confiscated his belongings after his death. Not much more to it than that. We do know that he thought Einstein was fundamentally wrong, his statements on the subject show that he may have misunderstood what Einstein's theories were, and there's a century of research affirming those theories he discounted.
New York City rent control
I can't speak to NYC, but Rent control in general is to prevent spiking of rental rates in a given area. So take a popular city like NYC or maybe San Francisco. As cities get massively popular, people want to move to them. However, that would also generally translate to land lords being able to charge rent prices well above other place because the demand is so high. However, that would also mean that folks who've lived in the city for a long time, working folks -- not richer folks, would be forced out if the land lord could charge whatever they wanted to fit the demand. Enter rent control. This puts a limit on how much the land lord can raise the rent. They can still raise it a bit, but it won't go from like $1000/month to like $2000 a month just cause the lease is up. This is good in some ways because it keeps housing a bit more affordable, but it's not so good in other ways because it can effectively trap people -- that is, if rent is spiking up around the city in general, the people may not be able to move out if their current place is all they can afford.
