The US is known as the "No Vacation Nation", the only developed nation without mandatory PTO.

It's not about what makes sense or not. It's about culture. Every person here is a decendant of an immigrant. It takes grit, determination and a strong work ethic to just up and leave everything you know and work your butt of in some new place hoping for a better life. Take the fact that we have self selected for people who generally embrace the the narrative of 'hard work above all else leads to prosperity', throw in our Puritan roots and our general distaste for the government intervening in our lives which dates back to the revolution. You end up with a culture that lends itself to this policy being viewed differently here than elsewhere in the world.

Why is that in the same room, same temperature, my boyfriend can be sweating while I am shivering?
|
There's a region in the brain responsible for temperature regulation, and it seeks to set your body temperature to whatever it deems best. That may vary slightly among people. When it sets your body temperature above what it currently is, you shiver - this rapidly burns metabolic fuel which releases energy as heat. If your set point is below your current temp, you sweat, as the evaporation off the skin will cool you down. Along with normal variation between people, even in yourself you vary about half a degree centigrade throughout the day. This can cause a fair bit of difference in how our body reacts to a temperature relative to someone next to us.

Why Microsoft is being fined more than half a billion euros for not giving a choice of browser in windows 7 installation and Apple is not.
|
Microsoft has 95% of the market. Apple does not. There is a much greater responsibility associated with having a monopoly. You don't expect the same thing from the king that you do from a pauper, nor should you. I also believe that Safari doesn't have the majority share on OSX.

Is there potentially an unlimited number of elements that can be discovered?
|
When you discover an element, the basic procedure is to take a heavy atom and a lighter atom, strip all the electrons off the lighter atom, and then shoot it at the heavy one. If you're lucky, the nucleus of the lighter atom will stick to the heavy one. Then you have several seconds to measure the atom you just created before it decays - the elements we're talking about are ludicrously radioactive and some isotopes have half-lives shorter than a second. There may potentially be stable elements with much higher atomic numbers, but we haven't managed to make any yet. It's called discovery because everybody knows there's an element with, say, 121 protons in the nucleus, but nobody's ever seen it. If you can make it, you're the first person to see it, so you discovered it.I don't think there is theoretical limit as how big an element can be. However as atom getting bigger, they are highly unstable. Practically falling apart in split second. a lot of them are barely long enough for confirmation measurement that they exist. nevermind collecting enough of them and do experiment. There is also this so called "island of stability" where certain nuclei size and combination can produce relatively stable atom. _URL_2_ . They are discovered, since they could naturally exist in condition beyond earth. . nifty video on some element discovery. _URL_2_

since https is secure why don't all sites use it? Why isn't it the default? Why even have http?
|
Encryption is very valuable for some things, but a waste for others. It limits the ability to use things like load balancers, and makes it harder to detect some types of network problems. It's probably a good thing for sites to at least offer it to users who want it, but using it by default does have some limitations.

Why are rising house prices considered 'good'? If anything else rose in price, it's usually not considered good.
|
Because most houses are owned by normal people not businesses - the higher price means that those people will get more money when they sell. The money they may owe on their house gets smaller by comparison. If you buy a 100k house and owe 100k on it then wait 2 years and house prices go up and it's now worth 200k your 100k owed is now 50% instead of 100%. If you sold it you would have 100k cash. Just because house prices went up. When gas prices go up it's not like people own lots of gas that they are waiting to sell - so it's a bad thing.

. Why do I go from being obsessed with a song to hating it after multiple listenings?
|
You probably just grew away from it. There are bands I used to just DIE over but now I'm embarrassed to have ever listened them", 'But conversely, when forced to listen to shit mainstream songs on the radio at work, does the opposite happen? 1st listen "Lady Gaga? *groan* This is so shit" 3rd listen "Actually, its got a good hook" 8th listen "This song is amazing, I'ma going to download it when I get home" 15th listen.."Dammit!"', "When you hear a new song, your brain thinks it's still very complex, therefore, interesting. After you start to understand the song, know how it goes, your brain just lose interest.

Is there something wrong with being honest with children about life, from a child psychology standpoint?
|
My nephews father, my brother died. Everyone told him that to see dad you have to die to become an angel. He was 6 years old at the time. 6 months later I found a comic strip he drew, as he was a kid who liked to sketch a lot. The comic strip showed him killing himself, then going up to meet dad. It took me about a week to figure out the best way to approach him about it. Eventually the best way I spoke to him about it was to ask him to show me his drawings. Then I pulled out the comic and said that I accidentally found this one the other day. I thought it was cool. But I wanted him to explain how he made a great comic. At first when I pulled out the paper, I could see how he was freaking out. He thought he was in trouble. I didn't want him to think so. To hide his talent to draw. To not trust me. So we spoke about his dad. I told him that his dad was my brother, like how he has a sister. And I felt bad that he was gone too. I told him that to me death doesn't mean we become angels, no one knows what happens. I mentioned that we all have a lifetime in front of us to live, learn and grow up, and keep drawing. He just finished high school and is planning to go to uni to study architecture.

How can people who make documentaries set up meetings with dangerous people? How do they convince criminals to get recorded?
|
How does Louis Theroux do it? By people trusting him. Why do they trust him? Because they've seen him with other people. He doesn't take in an agenda, he really listens, he probes but does so gently, he introduces topics to allow the interviewee to expand upon. If you feel you're going to get listened to and not exploited, it's easier to open up than a sensationalist.

How come technology has evolved SO MUCH in the past 30 years, but was basically non-existent for, like... the rest of human's history?
|
You're ignoring everything that isn't electronic. Technology has been super-rapidly advancing for about 200 years, and was advancing sorta fast for maybe about 100-200 years before that. The reasons? The scientific method, and industrialization. Industrialization lets us look at what science has discovered, and use it to make production more systematic. One of the most important inventions was the sewing machine in the middle of the 19th century. Before the, clothes were REALLY FUCKING EXPENSIVE. By making society richer, meanwhile, industrialization frees up more resources for research and science, so it *keeps going.*

How do people enjoy spicy food? Why eat for punishment?

Endorphins. When you eat spicy food your brain releases endorphins in response to the pain sensations. It's also delicious.

Why is there so much variation in the appearance of humans and relatively so little among animals?
|
Humans actually have very little genetic variation: Consider these facts: - Humans are global and just as in other animals we adapted to the environment. The same goes for dogs but they look a lot more different don't they ? - Wild animals are much more actively selected upon their immediate environment. For instance, a cat with a white coat will never work in a forest, while a tabby cat has a lot of advantages. The white coated cats die of quickly and we see a population of only tabby cats, thinking there is no diversity. But the genetic diversity generally is still contained within the genes of that cat. For humans, even for instance albinos can survive in modern society . - Looking at bird populations, we often don't see diversity outright. When we look at the bird calls/beaks and such we see however that there are often entire species subdivided in groups we considered to be homogenous at first. What I want to say with this point is that we often don't think as diversity in such terms.Not true. All Dogs are the same species and can make puppies but a black guy and asian look much more similar than a doberman and a jack russel. Edit: WordSecondary sexual characteristics -- > Socially constructed brains -- > Diversity of personalities + Lengthy gestation period = Greater variety of sexual characteristics selected, mutated, and spread. And then, Elevated intellectual capacity -- > High adaptibility -- > Wide proliferation of species across varied geography -- > Geographical adaptations + Continued proliferation of varied phenotypes and sexual characteristics = Fucking tons of human appearances.Your brain didn't ever need to be able to tell tigers apart, so you brain never evolved that ability. Telling humans apart, however, is very useful so our brains evolved to be very good at doing that.

Why do pregnant women crave to eat inedible things? My wife wants to eat bath bubbles and keeps a cup with her that has the smell of my body wash.
|
During my pregnancies I craved rocks/dirt. I also craved salt so badly I'd occasionally eat a pinch of large grain salt. Turned out I was extremely anemic and needed iron but my doc was insistent that those cravings were very common and that I shouldn't eat the rocks or dirt.

If stars have a spherical shape, why do we draw them with 5 points?
|
The points on a star is due to edge scattering on imperfections on your iris. So each star has the same pattern of points and each one unique to who's looking at it. No one else see stars with the same point pattern as you do. Add on top of that how they twinkle: starlight has to pass through the atmosphere, and changing density pattern affect the index of refraction, which cases what would a single point of light into a dancing light show unique to your position on Earth. The affect is then a twinkling sensation when you look at it.Stars might be spherical, but they are too far away to see that with the naked eye. To the eye, stars are a single point of light. Diffraction, refraction, and imperfections in your lenses often cause them to appear to have pointy rays emerging from them. The five pointed star is a way to represent those rays.Everyone's already answered the question pretty well. I always figured it to be an interpretative drawing style, much like how the way we draw hearts really doesn't look like a heart at all

why is the pinky more important for gripping things then the index finger?

"Speed monitored by aircraft" signs on the highway
|
Back before radar guns were cheap and readily available, catching speeders was hard. A patrol car had to covertly follow a speeder and try to measure their speed with their speedometer. Even then, the results were subjective, and didn't always stand up in court. As an alternative, some jurisdictions used aircraft. They'd paint lines along the side of the road a known distance apart, and an observer in an airplane would time how long it would take a car to travel between the lines, compute the speed, and radio to patrol cars waiting ahead. But with radar guns, monitory speed by air is very rare. Planes are expensive a 40 year old Cessna 172 will run you $50K, and cost $100 an hour to operate, apart from paying your crew. Radar guns and patrol cars are far less expensive.Both fixed-wind planes and helicopters have been used to check for speeding. In the past, they would use markings on the road and measure the time it takes a vehicle to travel between them. Today, they may be able to do the same with specialized radar equipment as well.

Why does Target have to pay a settlement to 47 states related to the 2013 data breach? Why not pay affected customers?
|
A few reasons: They failed to implement a rule or law that has a penalty. The State had to commit time to help people and 'clean up the mess'. Sometimes its just simply hush money agree to pay the State so they don't look to hard at the inner workings of how the breach occurred. I work at a Fortune 50 retailer and while on paper we are PCI compliant, I know that we do things that the processors say were not supposed to.. like keep CC numbers and CVS codes. While there are some gray areas CC numbers can be stored but must be encrypted. Well, if every CC en encrypted with the same key or hash its significantly less secure than a unique key for each card. So while we follow the letter of the rules we really don't do it the right or best way.

Why can apps like dominoes/UBER find your cell's location precicely but police/fire/ambulance cant?
|
[e911] has been mandated for years on the device & carrier side but Americans have become downright negligent about funding any government-funded infrastructure so very few emergency dispatch systems have been upgraded to support it. and Uber gets your location wrong all the fucking time. It might not be a big deal if your ride's a block away on the wrong side of the street but it's a *huge* deal if you're having a heart attack. Even when they get GPS information, it'd be stupid to *not* ask the address to verify it.GPS permissions versus cell tower triangulation perhaps. Although police absolutely can and do use phone gps to accurately track people as well. They may need a warrant to obtain your location data but still. They can. If police had access to your and everyone else’s phone gps coordinates it would be seen as an invasion of privacy. Violation of rights. Among other things.

If I dropped a pillow from 14,000 feet, what would the impact be like?
|
It wouldn't hit the ground very fast. Because a pillow have high air resistance compared to it's weight. So it's terminal velocity would be quite low. This is exactly the same reason you can skydive. You would fall really fast and die if you hit the ground. As your body doesn't provide much air resistance, so your terminal velocity would be high. But when you deploy the parachute you are increasing your air resistance, slowing your fall to a much lower terminal velocity.Terminal velocity makes things like this boring. If you want something dramatic, drop a hydrogen bomb.FOLLOW UP QUESTION: If I fell from 14,000 feet into a giant vat of pillows, would I be okay? I've asked this questions many times and never got an answer so this seems like the place to try again. Please finally settle this for me!

Why can't I feel treble like I can feel bass?
|
Our natural frequency is very low. In fact, if humans could hear lower than 20Hz we would be able to hear our muscles. If you apply a force to an object with the same frequency as it's natural frequency it will oscillate more and more. Think about [bridges swaying] and breaking in the wind; it's because the wind is at the same frequency as the bridge, not necessarily because there is more wind. Because bass has a lower frequency it is more true to our muscles' natural frequency, so we can actually feel our body vibrate when bass is low. At a really really low frequency unheard by the human ear our muscles would resonate and we would [lose control of our bowels.] You may have seen it on an episode of South Park.

Why are most screws either flathead or Phillips? Why not just one or the other? Are there advantages to different head types on screws?
|
First off, the driver type is called slotted, flat head refers to the profile of the screw. Slotted is clearly the simplest design to produce, less detail needs to be cast or cut into it. Philips and other conical designs add an improvement in that pressure will keep your driver centered. The driver styles like hex, Robertson, torx etc that go straight in offer the most torque, they also have another effect where the screw / bit is retained without pressure. That's preferable in some cases and not in others. A handyman wants to pull his drill out without hassle, but when you are assembling a phone you would welcome the stickiness.

How is it still profitable to make porn when there is virtually endless, high-quality porn online for free?
|
It's very difficult. Many studios are banking on niche genres, established and recognizable names and franchises and pursuing alternate revenue streams in order to keep a profit. There are still enough people willing to pay for porn to keep the studios running, but profits are not what they were in the days before tube sites. The truth behind many of the major tube sites is that they are actually run by the companies that hold the licenses for many of the porn sites you watch. MindGeek, formerly Manwin, which owns RK, Brazzers etc, is actually behind the operation of many sites including Pornhub, Youporn, Tube8, xtube and others. Ad revenue from these sites is hugely profitable for MindGeek, but still negatively impacts the bottom lines of the talent and the crew who produce the content. They are also not doing enough to stop the proliferation of piracy, nor are they compelled to meaningfully by the constraints of IP law. As a result, many porn A-listers resort to camming, escorting and featured spots as dancers. They are using their film appearances as promotion for these alternate revenue streams. This is all very interesting because it mirrors the changes in media as a whole as digital streaming rises to be the dominant paradigm in distribution. Musicians, new and emerging artists in particular, are being forced to pursue alternate revenue streams including commercial licensing, direct underwriting of content creation via patreon/gofundme/etc and an increased focus on touring and merch sales as opposed to album sales revenue in order to make a living. Streaming, while cheap and convenient for consumers of media, has hollowed out and fundamentally altered the distribution model to the point where a performance contract is no longer a guaranteed living for an artist.

Why do public transit busses have no seat belts but in cars and school busses, seat belts are required to be built in and worn?

it's because in public transit, people are constantly moving on and off trains and buses and because seat belts are expensive.You had seat belts on your school buses?

If muskets were so inaccurate, why did armies stop using bows and shift to firearms?
|
Building on what others have said in this thread, the musket was an improvement upon the crossbow, which was an improvement of the regular bow. The musket's range was slightly superior and had roughly the same firing speed as the crossbow. Musket balls were easier and faster to make in bulk through the use of molds than the tiresome and time-consuming process of making arrows by hand.Bows take years if not decades of dedicated training and an incredible level of fitness to use as a war weapon. You can make a soldier good enough for a musket volley with a few weeks trainingThe musket also had the ability to pierce thou armour better than a bow. Also since armies fought in large formations on both sides, volley shots were very effictiveMuskets are inferior to rifles but far superior to bows in most cases. You could carry way more ammo, have a much better range, roughly equal or improved accuracy, and it takes far less training to use one. Addionally you can add a bayonet and use it as two weapons in oneBows were also inaccurate in the way that they were commonly used during large battles. Archers would just fire towards the enemy and hope to hit someone.

Do different species perceive time as being faster or slower? How about different people?
|
We know that pigeons for example, process visual information something like 3x as fast as we do. I can't say for sure, but I postulate that means the world as they see it is significantly slowed down visually by comparison to us. In fact, they process visual information so quickly, they can actually be trained to guide missiles.I would think they certainly do, based solely on the fact that reaction times for many animals is much faster or slower than ours. Even for an individual, our perception of time changes. I write music, and when I listen back after getting off the treadmill , it almost always sounds slow My perception of the tempo of music changes drastically based on my own heart rate.My Neuroscience professor gave a lecture on how time is different for children compared to adults. I'll see if I can find something for you, if that's similar to what you mean?Beware, it's trippy af

Why am I compelled to pick scabs, even though I know it hurts / is unsanitary / etc?
|
This is speculation but my scabs itch the most when they're *just* about to come off, and it generally feels good to reveal the new and mostly healed layer of skin. Could exposing this skin earlier help it to strengthen faster?", 'As an RN, I dislike taking care of "pickers". Picking scabs may give you some pleasure, but it can grow into an obsession. Ive taken care of people with such infected wounds from picking it caused sepsis from MRSA she picked up. It is extremely frustrating to care for someone's sores from head to toe then come in an hour later to find their fingernails covered in scabs and blood crying, "sorry, I can't help it." Extreme cases are called dermatillomania. Just google it. Also remember our skin deflects millions of microorganisms a day. Its our first defense against infection. Not only are you tearing down that wall, you pick at it with your nails and fingers, the biggest germ spreader in history. So please stop, because your future nurse will thank you.For me, it's because I don't like bumpy things on my skin. My first instinct is to clean them off.

do viruses get nourishment for attacking our bodies? And if they do then are viruses that don't kill us more successful than ones that do?
|
Viruses don't really need nourishment, they aren't alive like bacteria. Viruses are kind of like turned off robots, they don't really do anything that requires energy until a certain trigger occurs, like having a button pressed on a robot. In a virus, the trigger is usually an incoming cell, which the virus will sense, activate itself which dumps DNA or RNA into a cell, and its function is basically done. The DNA or RNA contains instructions which is carried out by the cell to make more of the virus , which goes on to infect more cells. So in a sense, yes, the viron comes from our body's nourishment but no it does not need sustained nourishment. A successful virus is one that can reproduce more and spread from host organism to host organism without being wiped out. Also, yes, infections of any kind of microbe are more successful for spreading from person to person if the person is not killed. That is why most lethal infections come from diseases that do not kill other animals, but somehow are transmitted to us and happen to have lethal effects. Examples include HIV from primates , yellow fever from mosquitos, influenza from birds and pigs, ect.

Why do parents keep pressuring their children to go to college and take out school loans when there are all of these statistics about then national loan debt.

College is the lesser of two evils. You have to go deeply into debt to get a college degree, but it's the only way to even have a chance of staying in or making it to the middle class.

Why do people stare off into space when in deep thought? Is there a scientific reason behind it?
|
Try leaving your eyes open and not really looking at anything. What are you doing? You're thinking. Humans put a lot of emphasis on eyesight. If you're looking at something, you tend to be focusing your attention on it. When you're focusing your attention elsewhere, particularly on thoughts inside your head, you tend to stop paying attention to what you're seeing. So your eyes turn and focus at a comfortable angle - which is to say, probably at nothing specific.This may take some practice, luck, or just watching someone else do it, but if you catch yourself drifting off in thought, note exactly what your eyes do. They kind of "reset", typically looking straight forward 0,0 on the x/y axis. Your eye movement requires muscles to move them. When you aren't actively looking at something, those muscles stop and the eyes reset. It's also why your hands sort of hang awkwardly while you're multitasking sometimes; your brain knows why you wanted to move your hand and keeps it on standby whenever not being used. Otherwise every time you set down a can of beans, your hand would fall limp at your sideWhen you are "spacing out" your Dorsomedial Network becomes more activated. This is the part of your brain that reflects inwards and is correlated with mind-wandering.The Pre-frontal cortex on the other hand is in charge of executive functions such as sustained attention. Your ocular function are controlled by the PFC. When you are mind wandering, there is a reduction if PFC activation and more activation in this mind-wandering area called the PFC. Perhaps this is why our eyes look vacant when we are lost in thought.

Why do passenger car tires have speed ratings up to 186 mph?
|
For the same reason aircraft are not designed to barely produce enough lift with just enough thrust and a structure that couldn't withstand a single unpredicted loading/unloading or an extra lbf. Products are designed with factors of safety to keep the end user safe. Someone will push that airplane/tire/whatever past what it was designed for at some point, and it would be irresponsible to not provide some buffer to keep people safe.

Why do science labs always so often use composition notebooks and not, for example, a spiral notebook?
|
They're easier to store in a box and never look at again. But really I'm surprised the top answers are all missing how much easier it is to store your standard lab notebook than a spiral.A teacher once told me that spiral notebooks create the risk of getting tangled together if one of them has a loose wire, while composition books stack and unstack neatlyBound notebooks are required so that pages cannot be inserted at a later time. Tightly bound notebooks are required so that pages are not easily ripped out during normal handling. Numbered pages are required so that any pages that have been removed or inserted are obvious and easy to detect. This is all to help ensure that whatever is currently written in the book is the same as what was originally written in the book. This helps prevent fraud during investigations whenever the books are examined. Engineering and lab notebooks are often used as evidence in patent disputes, disaster investigations , lawsuits, and other official proceedings. Schools and colleges will require students to use engineering and lab notebooks mainly to simulate the real world. However, a lot of research conducted at colleges needs to be properly documented for the above reasonsIn addition, if you do any work with acids or metals, spirals are terrible. Acids corrode the spiral binding, and the spirals will contaminate any trace metal samples you are analyzingMy teacher had a bullshit excuse about how with spiral notebooks it is a fire hazard with it being open all the time since the pages are open and exposed.I work in labs and only use spiral notebooks. For me it's inconvenient for books to keep closing. It's also dangerous if your keep handling them in the lab and if you're faffing to keep them open. Great question!

If jellyfish do not have brains what drives them to stay alive as a species such as eating or reproducing?
|
They don't have brains, but they do have a network of nerves in their skin that can be thought of as a basic central nervous system. They have basic sensory organs that detect light vs dark as well as odor, orientation, and vibration. Sensory input will trigger movement towards the input and that can lead to food. Or it doesn't lead to food and they eventually die. Most of their behavior is just input=output reaction. There's no processing or storing information, planning, or thinking. A vibration sensing cell gets input and the output is a contraction of the dome to facilitate movement in that direction. If their tentacle senses touch then the barbs fire and toxin is delivered. There's no thought or choice in the matter. An organ fills up with enough of a specific hormone or reaches a specific temperature at a certain time of the year and sperm are released. They don't put on Jelly suits and go to jelly prom to dance with their jelly crush in the hopes of awkward jelly sex. They just ejaculate into the area and what happens happens. Then they die. The actual floaty balloon with tentacles phase is their mating phase and the only time when they have male and female organs. Most of the time they're boring little polyps on the sea floor just grabbing whatever floats by.

If a British Citizen committed a minor crime in the US, what could happen?
|
> My question is, if I, as a British citizen, carried a can of Bud Light down a street and we're caught what would happen? Deportation? Fine? Let off because I'm foreign and it's a sorta obscure law? The normal outcome would be, the cop gives you a ticket, tells you to pour out the beer and find a trash can for the bottle, and sends you on your way. At his discretion, he can choose not to write the ticket, and just have you get rid of the beer. Also at his discretion, he can arrest you and take you down to the police station to be booked and charged. That would usually be seen as an overreaction and a waste of time, but the consequences to him would be for his boss to tell him, *hey, lighten up, would you?* If he writes you a ticket, it will basically say, *You're being accused of having an open container of alcohol in public, in violation of State Code 101.974. Your trial date has been set for [four to six weeks from now]. If you want to just plead guilty, you have until [a few days before your court date] to just pay the $200 fine by phone or online or in person, and not bother coming to court.*", 'You would be arrested and punished just like anyone else. Ignorance is not an excuse for violating the law. Being a foreign citizen you could also face your visa being revoked and you being deported. Any criminal violation can technically trigger this, though most minor things will be ignored.

Why can my Mexican grandmother and father eat extremely spicy food, yet I, a Non-Mexican Canadian, can not? Shouldn't the gene of being able to handle spice pass on to me?

It's not a trait one inherits. It's something one gradually gains the more you eat of it. Growing up in a Mexican household, we were eating something spicy at breakfast and dinner 75% of the time.

Why is there an FDA ban on accepting blood donations from gay men?
|
The ban is on men who have ever had sex with other men which overlaps mostly with gay men . The reason given is largely due to the relatively high incidence and prevalence of HIV in men who have sex with men. Although all blood is screened for HIV, the tests have a small false negative rate so certain groups of people that the FDA believes are at higher risk are prohibited from donating. But it's partly also due to bureaucratic resistance. ]Other countries have relaxed their bans] to 12 months in the UK and 5 years in Canada instead of the current lifetime deferral in the US. Screening based on other risk factors can still keep the blood supply safe, but the FDA doesn't believe it has enough evidence to safely change its policy. It [says] that it's conducting research into changing the policy, but it doesn't seem to be progressing on it very quickly.

why it doesn't matter how much you spend on a HDMI cable, and then how some retailers end up charging so much?
|
One thing that hasn't been mentioned yet is that people are generally willing to spend more money on an accessory for a product that they already paid a lot of money for. Keep in mind the people buying expensive, over-priced Monster cables probably just bought an expensive TV. Shelling out an extra $100, for what in their mind is the ultimate experience, is a pretty easy thing to rationalize. It's like when you buy a new computer/laptop. Perhaps you might easily spend $20 here, $50 there, even $80 here for a fancy case - easier to justify since you just spend hundreds if not $1,000 on your new machine.Many people are dumb. The smart people try to figure out how to take as much money away from the dumb peopleThere are two different kinds of cables; analogue and digital. Digital cables are used to transmit digital signals; HDMI, DVI, etc.Analogue cables transmit analogue signals; Composite , Coax, etc. Digital signals can be thought of as lights on or lights off.Analogue is more of a dimmer switch. Digital cables are basically all the same, the signal is the same as long as the cable works. Analogue cables can be different depending on the quality of the wire, shielding, resistance and interference. Basically cheap Digital cables are ok, but cheap analogue can some times suck depending on usage.It's about price sensitivity. Most people are very price sensitive about their TV. So they look at ads for the cheapest place to buy. This drives down margins on TVs. Then they get to the store, and oh, I need a cable and just grab one. Stores know this and jack up the margins on the cables. As an educated consumer you can be price sensitive on both, and place your order at _URL_0_ for your cables.

How can Donald Trump, with most of the Republican party damning him, still lead in the straw polls?
|
Because Trumps candidacy is either taking advantage of or designed to expose a massive cultural difference between the rank and file membership and senior leadership of the Republican party. Both parties are very broad coalitions of groups that sometimes have pretty different interests, but agree on a few key topics . The wing of the party that Trump's statements are designed to appeal, is made up of people who mostly don't feel like they've gotten many benefits from the coalition recently.

; Are parents legally obligated to name a child? If not, does the state appoint one? Can I name my kid nothing like "_________". Are numbers/punctuation allowed?
|
Here in Germany, the state considers the needs of the child to avoid being abused by others because of their name to be more important than the creative needs of the parents. There are some restrictions. Boys names may be selected for boys only and girls names for girls, respectively. The only exception is the female name “Maria”, which may also be used as a second name for boys which was common in Catholic parts of the country. The name must not be absurd or degrading in any way. Last names, product names or names of objects are not permitted as first names in Germany. So you can't name them after nouns, i.e. apple, or places, i.e. Berlin. They cannot have more than 5 first names. The name must ultimately be approved by the Standesamtbeamter that processes the birth certificate. There is some leeway given to foreign parents. For instance, if the name you choose isn't in the list of normally approved names, then you will recieve a chance to prove the name you want is in use in your own country. Every child deserves a name. If you do not name them the state will warn you and then issue them a name. Nothing archaic, or ridiculous, just one of the top ten names from the year previous. Edit: Foreign.[Falsehoods Programmers Believe About Names] is great fun. The #40 falsehood is "people have names", so I guess some people just don't.So you can't name your baby: Princess Consuela bananahummock? Darn..

What is the point of the Riemann sum if the integral renders it obsolete?
|
The Riemann integral is *defined* as a limit of Riemann sums - you need them to prove properties of the Riemann integral, such as linearity and the fundamental theorem of calculus. There are other ways to define an integral, such as the Lebesque integral, which is defined for a larger class of functions than the Riemann integral . The Riemann integral is usually introduced first since it doesn't require measure theory.

Why do children, teens, and young adults seem to share a common anxiety towards talking on the phone?
|
I think some of it is how you're brought up by your parents. In my house before mobile phones, the telephone was something only adults used and me and my brothers were told never to touch it. Also as a young kid I remember my parents having to make various important calls and each time everyone had to leave the room so it was quiet and they could concentrate. It just made everything about the phone really weird and scary. I remember getting a job when I turned 17 and suddenly I'd have to start using the phone and it scared the crap out of me. Maybe today's children who grow up with mobile phones won't experience this - or maybe they will because they'd prefer texting/online chat etc. Weirdly enough I still get really nervous and put of phone calls I make while outside of work, even though when in work-mode I spend ages on the phone.Im the opposite, I would much rather have a 1 minute conversation that gets all the needed information across instead of 15mins of texting back and forthBecause non verbal communication is just as important as verbal communication and on the phone that just goes out the window.

Why is voting turnout in US Elections so low?
|
Political influence of the Republican and Democratic Parties keeps most people from turning up. Politics is really black and white in America, at least what you see in the media. It's like have to pick between the lesser of two evils. It is near impossible for anyone with a different political party than the ones mentioned to be able to represented. Its the reason why Democratic Nominee, Bernie Sanders, had to run as a Democratic Socialist. He wouldn't be a runner in the Presidential election if he hadn't added democrat to his political views. The reason why turnout is poor is because people rather abstain than take part of a fixed political system. Your choices are made by electoral colleges, not by the American people. Popular vote does not equal Presidency.

Why can't I burn fat and build muscle at the same time?
|
Well, It's a bit misleading. The main thing to understand is to build muscle you need the calories to do so. If you are using more calories than you intake you lose weight. That said if you have reserve energy, in the form of fat, that will be converted and used to process protein into muscle. What to take away from this, is unless you already work out a lot, you can", 'If you are a normal person, you can. Strength training, cardio, and diet, and you will lose weight and gain muscle. If you are a bodybuilder, and already have big muscles and low body fat, then you have to make some choices. Your body thinks it has enough muscle, but really wants more fat. If it has excess calories, it is going to try hard to turn them into fat first.

How does the fifth amendment work?
|
That's why you invoke your 5th amendment rights and don't say anything. You are not lying, and you and not self-incriminating yourself if you state that you are invoking your 5th amendment rights. That's not considered to be withholding information, because the rights are in the Constitution.

If the body burns excess fat for energy, why can't obese people go weeks/months without eating?
|
Imagine a car that's also capable of repairing itself. A car that can rebuild its own oil filter, replace its own oil and brake fluid, rebuild pistons and gears as they wear down. All you have to do is put gasoline, raw iron, oil, water, and other chemicals into the tank. Gasoline is analogous to fat and carbohydrates in your body: it's just there to provide energy. The iron and oil and water are analogous to the vitamins and minerals and salt and all the other nutrients in your food: they are building materials your body uses to maintain your organs.There are a few nutrients that your body cannot make for itself. Even though obese people have a lot of stored energy they still need essential amino acids and various vitamins and minerals to survive.Fasting with only water and vitamins is bad business. You can do it if your body has enough fat, but your muscle tissue degrades, resulting in your metabolism degrading.PMSF is safe, and is the lowest calorie I'd suggest (prolly 600-900 calories of ~all protein for most. This is clinically proven to be effective with minimal muscle loss._URL_2_

Why do wine glasses hum when rubbed.
|
When you move your hand across something, , you also make a noise. That noise/sound energy travels through the glass through sound waves. If the sound wave is of the correct length , you will hear a 'resonant frequency'. A resonant frequency is when the sound wave rebounds off something, and doubles up onto itself should give a visual representation of constructive interference , where the bottom waves represent the initial sound wave and the one being rebound.

The causes of WWI.
|
The basic version of it was that it was simply too much effort not to have a war. In order to prevent a war in Europe, two super blocs developed: the British, the French and the Russians on one side; and the Germans and Austro-Hungary on the other. The idea was to have two vast, opposing armies, each acting as the other's deterrent. That way, there could never be a war. Unfortunately for all involved, this plan was utter Bollocks. And the poor old Osterreich died for nothing ", 'I am not demeaning your question but I think you 've answered it yourself. With all the different treaties and alliances in play, when a spark, the assassination occurred. all of those came into play. X said to Y, how dare you? A said to B, I need you. H said to I, "you promised" Obviously one could expand on this for thousands of pages but it is, after all, ELI5. And you can't always blame everything in that part of the world on the BalkansIf you're interested in an Explain Like I'm 14+, Dan Carlin has an amazing ongoing podcast about the cause and context. The episode is called "Blueprint for Armageddon." _URL_0_

Why do so many species enjoy being rubbed or scratched?
|
Most of the species that we like to rub or scratch can't reach specific parts of their bodies any other way, which similar to humans triggers a certain sense of pleasure. Who wouldn't enjoy a good back scratch right now :).
|
If cold symptoms are signs of your body fighting off a virus, why aren't medicines that suppress these symptoms bad for you?
|
Most of the time those symptoms are an *overreaction* from your body. It's a similar reason why your body might show flu symptoms after getting a flu shot. The body goes into full fight mode even when the virus isn't going to do much. Fun fact This overreaction happens more in Caucasians as comes from the same genes that give European descendants a better resistance to the black death. So maybe don't suppress those symptoms if you catch the plague.
|
Why doesn't our body activate self-preservation mechanism when people have suicidal thoughts?
|
An evolutionary benefit is for a species as a whole, not necessarily for each and every individual. The normal sense of self-preservation does work for the majority of humans, which is why humans continue to exist. Bottom line: Evolution is not a conscious entity that cares one way or the other. Whatever features of a species as a whole that work to keep the species procreating *is* natural selection. Individuals are irrelevant on that scale .

How do fans collect so much dust even though some are spinning almost all the time?
|
In non turbolent phenomena the fluid has zero speed with respect to the surface it is sliding on. The same way, the air flowing through the fan should present non turbolent state and can't blow away the dust.So the dust is collected mainly when the motor is off, but also because the blades attract dust from neighbour layers of air that are moving.Fans move air. They are in contact with more air with dust in it because the fan moves air through it. They act like a really ineffective air filter by sometimes hitting dust in the air that then gets stuck to the blade for different reasons because the fan blade has a blunt edge after all. More dust collects on the blade and dust itself is sticky to other dust and create a a bonding surface for yet more dust. A more efficient inefficient filter is born!You hit more rain water when you are running than if you just stood in the rain. Dust particles in the air are like rain, and the fan blades are running through the air hitting and collecting more dust than if they just stood still.

If telomeres shorten with every cell division how is it that we are able to keep having successful offspring after many generations?
|
This is tied to stem cells and telomeres, as others have said. Cells can either differentiate and lose their replicitive capacity or remain undifferentiated and keep their replicative capacity. But don't see this as only two states; it is more like a spectrum. Stem cells are on the undifferentiated side of the spectrum, and it is their daughter cells that tend to differentiate. Remember that when a cell replicates, it makes two copies of itself. In the case of stem cells, one of these will go on to become a more specialized cell, and the other will remain a stem cell. Therefore, a stem cell could be defined as a poorly differentiated cell that tends to maintain its own population. But there remains the problem of telomeres. Whenever these stem cells divide , their telomeres will shorten. This is countered by the enzyme telomerase, which binds to the shortened telomere and adds base pairs . The stem cell in the gamete population is either the spermatogonia or the oogonia , and their products are differentiated cells which should lose telomerase activity. If differentiated cells keep telomerase activity, or if they somehow recover it, they could cause problems such as cancer. It seems even stem cells lose their telomerase activity the more they divide, and this is thought to be one of the causes of senescence in a cell and in an organism as a whole.

Why Aren't Supreme Court Cases Always Filmed?
|
The reason Congress is filmed is largely so that politicians can grandstand. The actual work of Congress takes place almost entirely off-camera - what you're seeing is just the theatre of Congress. The Supreme Court has no particular need for this sort of positive publicity and they understand that filming the proceedings will leave them open to all sorts of irrational criticisms because people tend to view video as 'reality' without realizing their perception is highly manipulated by the framing.

How do mining companies know where to make mines? How do they say: "Hey, there's a lot of gold/silver/platinum/iron underground" without making a mine?
|
I am a geology student and I know about this a little. Actually before mining at lot of surveys are done, such as seismic survey, gravity and magnetic survey, just to know what is the subsurface geology and makeup. Mining gets most benefit from the gravity survey. Using a gravimeter, they take a note of minute changes in the gravity at different places, with respect to some standard reference point. The changes in the gravitational acceleration can be attributed to the change in the subsurface. For example, if there are only sedimentary rocks over the basement rocks, then the gravimeter would show a specific value of difference in gravity, but if there's a salt dome, within the surface, the gravity would decrease as density of salt domes are relatively lesser, and hence we get a negative difference of gravity. Similarly, based on the sign and magnitude of difference in gravity obtained from gravimeter, we can know whether the place is worth mining for minerals or not. However these surveya are reconnaissance surveys and.. Are generally used alongside some other techniques. Results from one technique or method, is never taken as correct in geological surveys, other tests are always run, to check the validity of previously obtained results.

Why do our bodies think that when we're nervous or scared it's a great time to urinate?
|
I have complex post traumatic stress disorder. One of the symptoms of it is something known as hypervigilance. I have fairly severe hypervigilance. My body is essentially in fight or flight mode 80-90% of the time I'm awake. The fight or flight response is handled by the autonomic nervous system. This nervous system is responsible for a wide variety of things, on top of fight or flight it is also responsible for *urination*! The amount of times I have to go pee in a day was actually one of the reasons I suspected I had CPTSD. Another thing the autonomic nervous system is responsible for is swallowing. It's why when we get scared or nervous we compulsively swallow. If the nervous system gets active it seems to activate all of the parts. So when you are scared or nervous your body goes into fight or flight mode. This activates the autonomic nervous system. The system is responsible for urination and so when it becomes over active it causes those things it's responsible for to activate.

What happened to Occupy Wall St.?
|
There were simply too many issues with the movement. 1) They claim to represent the 99% but clearly only represented a small portion of them. Successful movements represent the people they claim to represent. When a drum circle starts yelling they are the 99% it's pretty easy for the 90% of the 99% to laugh them off as kooks. 2) They decided in some cities to become anti-police and anti-government. Portland, Oregon is such a great example. City hall bent over backward to accomodate them. Then eventually the city had to say no to a request and suddenly the city leaders were the enemy. 3) They were rude neighbors. They took over parks so others couldn't use them. They started moving into residential areas and be loud all night. They have the right to assemble but people also have the right to peace and quiet in their own homes. 4) They never had real action steps. There was never any what next. 5) They protested the wrong people. Democrats were in charge of government and government is where to enact change for what they want. Instead of protesting the Democrats controlling Congress and the White House they protested Wall Street and financial areas. They had no real influence over those areas so it was easy for them to be ignored. If they had gone to DC or state houses they could have prompted legislative change which is what they claimed to want. Occupy DC I think would have had some impact. But that would have meant protesting the same people most of the participants voted for. 6) They thought they were the liberal version of the Tea Party. The Tea Party was also full of kooks but they focused on things they could actually influence: Politicians. Occupy Wall Street focused on the wrong things to protest. 7) Hipsters and Hippies misunderstood how little people think of them.

When, and when don't, antibiotics work?
|
Antibiotics work by targeting processes bacteria cells do, but non-bacteria cells don't do. This is how they kill bacteria causing infections. They don't work on viruses because viruses don't really have any biological processes of their own, so using antibiotics for non-bacterial illnesses doesn't help. Taking antibiotics for less time than you should may end up leaving a few stragglers alive, who could reproduce and start the infection all over again. Taking antibiotics for too long isn't quite as bad, but there will be side effects, so it is not recommended. One major concern is killing all the helpful bacteria that live in your intestines.

Why do most businesses have a 1-800- number?
|
Back before cell phones, you had to pay for long distance calls, and it wasn't cheap. An 800 number allowed you to call long distance for free, with the recipient picking up the tab. These days it is less important, all though there are still people who use landlines and pay extra for long distance. Mostly everyone is so used to 800 numbers and they are easier to remember, so business keep using them.

How are Political Action Committees (PACs) legal in a democratic state like the USA?
|
How does the existence of PACs affect your right to vote? The constitution says Congress shall make no law that infringes the freedom of speech, and the Supreme Court has ruled that -- in a democratic state like the USA -- where sovereignty is derived from the people, that political speech *especially* deserves that protection. If a labor union thinks a certain candidate's policies are better than the other's, why shouldn't it be allowed to accept donations from its members and use them to inform the country on how these policies might affect jobs? Consider the extreme alternative. Congress actually has quite the incentive to make extremely strict rules restricting political advertising. Imagine they make it illegal for anyone to broadcast any electioneering message. How would anyone ever hear about any politicians other than the ones already in office?

Does repeatedly hitting the snooze button in the morning provide any sleep benefit, or does it just prolong the agony of having to get up?
|
During sleep your body produces melatonin that makes you feel super relaxed. When you wake up, melatonin production stops but there's still enough in your system to keep you drowsy. Waking up by alarm and hitting the snooze may allow you to stop producing melatonin and work out the remaining melatonin and feel less sleepy once you actually get up and moving.

Why time travel cannot exist
|
you cannot travel backwards in time because you cannot travel faster than thespeed of light. traveling back in time would also be a logistics nightmare because time and space are linked. If you travel back 60 seconds you'd probably be sitting in the middle of space because the earth wouldve moved a few thousand kilometres away.If it would exist, we would know about it since someone from the future would have done it alreadyIt has to exist, how else are we going to send Kyle back to defend/fuck Sarah?', "Okay, as we're explaining it like you're five, and I'm not remotely a scientist or particularly scientifically minded so wouldn't be able to do a proper job of it anyway: Because we don't *really* understand how time works. I mean, at *all*. We've got a sense of *how* gravity functions, if not how it *works*, but time really is a bit up in the air. Except it isn't up in the air. Probably. Can't work out ways to mess with a thing when we're not even sure in what ways it exists.Well technically, we are already traveling through time.

Why can't computers store data without fragmenting it?
|
Imagine your hard drive is a notebook. The first few pages are an index telling you what page every file starts on . FAT32 identifies a file by the first page it's written on and ext2 identifies each file by a number called the inode number. A directory is just a special file that says what the name of the file is and what file number it is. A file system like FAT32 is not all that smart. It writes the first file on pages 6-10 and the next file on pages 11-15. Later, you need to write more to the first file. You can't write on page 11 because that has file 2 on it already so you start writing on page 16 and go to page 18. You delete file 2 now and write file 4. You start at page 10 and write until page 16. You still have a few more pages you need to write and so you continue on page 19. You now have 2 fragmented files. Imagine what would happen if you did this every few minutes for a few years. A more advanced file system like ext2 will start the first file at page 10, the second file at page 20, and the third file at page 40. After a while, there are no pages with empty space around them and the file system does end up fragmented, but this only generally happens when the file system is quite full. As long as there's a fair amount of free space, the file system does a fairly good job of keeping the files defragmented. The notebook analogy also shows why fragmentation is bad. It takes a lot more time to go from page 10 to page 16 than it does to go from page 9 to page 10.

What's the hold up with the ability for residents to text 911 for emergencies? Is it a technology-related problem? Jurisdictional?
|
Some regions do allow you to text your national emergency number. In the US, some regions do allow it. As for why others do not, it's simply because it costs extra money to implement, both for the carriers and the call centers, which don't have a huge budget.It's technology limited. Texting "help me" to 911 doesn't do anyone any good when it literally could come from anywhere in the world. Meta data about location needs to be sent as well and systems designed to accept and forward that information are required.

Why does the human body continue to store fat to the point that it causes serious and life-threatening health problems instead of excreting it as waste?
|
Hmmm this is a great question. I'm going to give my educated opinion. I would say that it has to do with generations of our ancestors living as nomadic tribes opposed to the relatively small time we have been sedentary. Evolution hasn't caught up, so our bodies and hormones still think there could be a bad time of no food at any point.

How do space agencies keep up with new technologies in their projects/missions?
|
For most space missions, upgrading to stay up to date is a danger rather than function. For example, New Horizons, the spacecraft that launched to Pluto in 2007, launched with a 2GB flash drive. Why 2GB when commercially available 8gb drives were readily available and used? Well. Safety was a concern. No one had tested the reliability of an 8GB drive. So, to ensure that a critical part of the mission wouldn't fail, they used their originally designated 2GB drive.

Why is Australian Internet so bad and why is just accepted?

It's not accepted. Our old left wing government started to build new fiber optic internet capable of 1gig connections. The conservative government came in and gave all the money put aside for it to our biggest telecom company to buy all the old, worn out copper wiring and spend a decade upgrading it to around 25mbs. tl;dr: We had super fast internet coming, right wing government gave it all to a big company instead.

I'm currently passively watching a mod of a private sub that I want. He is just sitting on it and not doing anything with it. Its been over 10 months and he is still the only member.Its simple. A friend of mine and I made a sub /r/legoblackmarket reason being cause he and I are both tired of doing one for one trades with lego. Its pointless once you get quadruple digit set count. So we invited the people that we knew had about the same high amount that would like to trade. We also find craigslist ads in our respective areas It helps us to further our collection much faster. Before we were limited by distance but now we are not. Reason its private is cause we have a few people we dont want knowing our secrets to finding cheap lego in retail as well as it keeps the bots out.Could someone tell me what's hiding in /r/vikings

How can we know for sure elections aren't rigged/paid to win?
|
Statistics can be used for this. Mathematically, large groups of people behave in fairly consistent ways, and we can measure that and use it to double check election results. The results from statistics come in the form of intervals, so some voter fraud can take place, but if it's pushed beyond the interval we have a red flag to double check those results. Or at least that's the assumption, voting is inherently political, and anything with politics can get messy fast.

What would happen if I soaked my body in a tub of vodka?
|
You would kill all the natural flora on your skin. And as a result you may get some weird opportunist topical infection. Also it would dry out your skin, and prolly make it unhappy in general like a rash, irritability. It would be fine after a few days though I think. All the people saying you would get drunk from absorption through the anus, there is this thing called sphincter that keeps stuff like that from happening. Unless he injects the alcohol into his anus this wouldn't happen.

Why do Americans have to pay for an ambulance if someone else called it for them?
|
I think I need to step in and clarify a few things here. First, as others have mentioned, if you're in a state of mind to refuse an ambulance, you can go ahead and do that. Now, I don't care what country you live in, if you get taken somewhere by ambulance, *someone* is paying for it. If you're in a country with socialised healthcare, it's the government. The US is thought by most people not to have socialised healthcare, but this is only partially true. There are many government programs that pay for healthcare. More now than a decade ago, imperfect as the new ones are and hobbled as they re becoming. So there's a decent chance that if you are an American and someone called you an ambulance, the government is paying for it. Barring that, you probably have private insurance, and *they* are the ones who will pay for it. Now, many private insurance programs will have various fees and copays for services, including ambulance service, **but this is not uncommon in countries with socialised medicine**, either. Your insurance might be charged a few thousand dollars, and you'll have to pay $100 out of that . Only if you have *no* insurance will you be billed directly yourself. And when that happens, that's when it makes a huge noise and people outside the US hear about how someone in the US is now $100,000 in debt because of medical costs.

why does it feel so strange when you step onto and off an escalator that is not working, it's like even though you know it's not moving your body still anticipates it's moving
|
My 18 month old son loves escalators. He saw one the other day, ran over to it, and very cautiously stepped on, anticipating the movement. what he didn't realize is that it was out of order. When the magic stairs didn't move he jumped up and down a couple times, then plodded off looking mildly disappointed.This is sometimes known as the "Walker effect", though I prefer the term "escalator wobble". Normally you have to take a faster step onto an escalator than you would on stairs. Muscle memory means that you are still prone to do this, even on a stationary escalator. There is a wiki article on the phenomenon here _URL_0_', "One thing the others left out: unlike a regular set of stairs, the steps of the escalator *ARE* moving a little bit even when it's broken, because they aren't firmly affixed in place. There actually IS a little bit of movement that you can feel.

Why has it taken 9 months for Dzhokhar Tsarnaev (one of the Boston bombers) to go to trial even though he was identified and captured just 4 days after the bombings?
|
There are pre-trial hearings that they have to go through. For instance, the defense team moved to suppress the evidence that Tsarnaev gave by responding to questioning while in the hospital. According to [the exclusionary rule], if that interrogation is deemed illegal, the prosecution couldn't present any evidence from it to the jury. ================================== Folk interested in the rules regarding criminal procedure should read more of [The Illustrated Guide to the Law] a webcomic drawn by a practicing defense attorney from NYC. It also has sections on: * [traffic stops, searches, and consent] * [self-defense] * [entrapment] * [memory and eyewitness identification] * [the history of interrogation in Common Law] And flowcharts for [the 4th amendment] and [the 5th amendment]

The AK-47 was invented in 1946. More than 70 years later, in 2016, in what ways are modern guns better than it?
|
The Chinese made a very good and arguably better version of the ak47, the norinco mak90. I own one and added a red dot sight to it. I would rather bring it into battle over an ar15 because it's simpler and shoots just as well at normal shooting distances of ~100 yards. It shoots cheap surplus steel case ammo no problem. . Ab AK 47 is still a great weapon. Ar15=more complicated, therefore more can go wrong. I own both, I must say for home defense I would use a short barreled suppressed ar15. Imagine an ak47 as a reliable early 90s Honda civic. It's going to be old but reliable and cheap. It will do the job but there are prettier cars that would be able to do more. Edit: more words

Why is Smoking still a thing despite apparent massive health risks and warnings?
|
Alcohol brings out the love for tobacco in many people. I know lot's of people who don't smoke, but after some heavy drinking they are lighting up. This goes double for Las Vegas, you can smoke almost anywhere in that town.

Why is Final Fantasy VII so highly regarded?
|
The Completionist made quite a well-rounded [series] that explains in detail on quite a few things involving the FF7 series. There are spoilers and he talks about more than just the Final Fantasy 7 game, but there is a lot of good information there if you're looking to spend a while analyzing these kinds of things. He also brings in guests who talk about what FF7 meant to them at the time and all that stuff.Are we forgetting that the soundtrack also was just superb. composed by Nobuo Uematsu on a MIDI system with just default computer generated sounds. but at the time of playing it felt like an entire orchestra and symphony that fitted perfectly into every battle / story sequence. I mean come on, the boss soundtrack just made you feel pumped up. [link]', "I still think the Materia system is fantastic. It allowed for so much customization. It created a grind if you wanted it, but it wasn't really necessary to grind either.I bet you cant see why kids love cinnamon toast crunch either.. philistine ', "Let's be honest the story's so relative it's a sudo religion.

Why is 10 degrees celsius not exactly twice as warm as 5 degrees celsius?
|
It all has to do with the type of scale something is. The Celsius scale is an interval scale because it has a clear order and the difference between units is equal, thus allowing for addition and subtraction of units, but it's not a ratio scale because their is no true zero As others have mentioned the Kelvin scale is a ratio one so you can then do multiplication and division with the data. [A source on the matter].

If "Classic" cars are so desirable/good looking, why don't they make more just like them?
|
I disagree with most of the explanations given which rely on technical differences. I think the main reason is buyer psychology. No one cares about or desires a 'fake' antique. It's not that classic cars actually look better or perform better; they are sought after *because* they are classic.

Why aren't white people in the United States referred to as "European Americans" like how blacks are referred to as "African Americans?"
|
You might get a much better answer from /r/asksocialscience - they're actually required to cite sources and have some sort of prior knowledge about the field. Here you're just going to get defensive or aggressive political poppycock.it's because whiteness and white culture are considered the default american state. just like white hair care supplies are the default and black hair supplies are sold in "ethnic" sections.

Why is everyone freaking out about the Deadpool trailer? I've never even heard about Deadpool until today.
|
I never thought there would be a legitimate upside to not knowing who Deadpool is, but if you don't know who he is then you probably never saw X-Men Origins: Wolverine. Which is a definite upside.

Why is it that so many of us humans have this fascination for violence (at least to some extent) even when we may deem it unethical?
|
If it weren't attractive, we wouldn't need to consider it immoral. Violence, aggression and dominance are all wired into the human psyche; we're primates after all. And fantasizing about committing acts of violence is always going to hold a certain fascination. The fact that we suppress or sublime those impulses for the sake of a better big-picture outcome doesn't contradict that, any more than enjoying the sight of rich food despite being on a diet.

If i were to use a random number generator, and then go back in time to just before i used it, would i then get the same number, or a different one?
|
If it's a truly random number generator , then no, there are no factors in generating a number. If it's like almost every number generator, then it should produce the same number.

How sharp is paper?
|
It's not paper that's sharp, it's your skin that's soft. Seriously, feel that shit. It's very stretchy and mushy. Flexible, strong if you pull it, like elastic. But like a rubber band, easy to cut. This is just my guess, and it feels right, so I'm hoping I'm right.

When someone sues for a large sum of money, how does the losing party pay for it?
|
Insurance, savings/investments, or sale of assets are the common ways. If they can't pay, the winner can usually get a judgement which will allow sheriff to seize some of the loser's assets or garnish wages .

How is the federal budget $3.9 trillion when only $1.25 trillion is in circulation?
|
_URL_3_ < - 2.8 trillion is in circulation, but of course there's private business also spending M1 money as well. _URL_3_ < - Velocity of money.Velocity of money basically means this: 1 schmuck buys a widget at a store for $10. The store owner pays his employees and suppliers $7.50, and pockets a few dollars for his retirement.Those employees and suppliers pay their employees and buy goods for $5.63 and pocket the rest for a rainy day or retirement. This continues on and on.Thus it follows a geometric sum: _URL_3_1/, or in this case 1/= 4 or a velocity of money of four. This is just simply an example, reality is a bit more complex. In fact it is so complex that no economist can sufficiently predict the future of the economy to any accuracy.

Why does cracking knuckle and other joints only become necessary after a person has started doing it regularly?
|
Specifically referring to your spine: You shouldn't do this without learning how to also protect your muscles from damage. _URL_0_ _URL_2_ _URL_1_", 'Here is a question, and a little TMI. Why does the neck crack so well during an orgasm? Like during sex or even two minutes afterward, it does not crack. But during an orgasm, simple movement causes like six cracks.Been in the same boat as you for a while. It started with just cracking my first set of knuckles, but then it got to where I'd start cracking every joint in my fingers and eventually even started trying to crack both joints in my thumbs when I could . Then one day I distinctly remember leaning on my wrist and it cracked loudly, and I started cracking my wrists. Then I started pressing my toes against the floor and pulling them to crack toe joints. Then I started leaning on one knee a certain way to crack my knees. Then I started quickly extending my elbow to crack it. Then I progressed to cracking my back while sitting in seats by holding my legs in place and turning my torso, and finally turned to cracking my neck either with my hands or by turning my head side to side rapidly. Nowadays sometimes when I raise up or sit down I feel my hips crack, can't do it manually though. I get the feeling life is really gonna be miserable for me once I get into my 40s or so.Ill add that the general consensus is that popping knuckles doesnt actually cause arthritis. Arthritis like many ailments is mostly hereditary.

How is it determined how many calories (including fat/protein/carbohydrates) are in an item of food?
|
Didn't see the second part of the question at first. Fat, protein, and carbohydrates aren't measured the same way as calories. They're measured individually using chemicals that react with the individual part. So there's a specific test that reacts with sugar, but not protein or complex carbohydrates. And another that reacts with protein, but not sugar or carbohydrates. Etc.

So we are seeing the Sun as yellow but why are we seeing it's reflection from Moon as white?
|
> ELI5:So we are seeing the Sun as yellow What sun are you looking at? [The sun is white.] Maybe kids draw the sun as yellow, because they don't like to stare straight at it at noon, but instead want to look at it during sunset/sunrise when atmospheric scattering makes it appear more yellow/red. Interestingly, most Western kids draw the sun as yellow, whereas Japanese kids draw the sun as red . So the sun is white and the moon is white.

In laboratory experiments that test illegal drugs, like the effects of cocaine on rats, how do scientists legally acquire and store the drugs?
|
Cocaine is used legally by doctors, particularly in the sinus surgery field, because it's an unsurpassed anesthetic and vasoconstrictor. Doctors, after doing loads of paperwork, can get it through legal channels. One would presume lab scientists would do the same.I work with a client at a toxicology lab doing post-mortem examinations. They have a safe, inside a fridge, full of all the "standards" they need to calibrate their instruments with. They make "spikes" of these compounds in solution, at known, concentrations and compare samples to them. Some of the latest "street drugs" like fentanyl and carfentanyl do not have a manufacturer source to order pure samples from, so the lab uses confiscated drugs from the police as a standard. They simply compare levels they see in blood samples to the highest purity samples of these drugs they have ever found.Neat-o!The government sanctions one or more companies to produce the drug for research purposes, and any scientist wanting to research with a drug has to buy it from that one company. For instance, the University of Mississippi is the only federally sanctioned source of Marijuana in the US for research purposes, and CocaCola corporation is the only source of Cocaine for medical and research purposes

Why did the first 20 years of my life seem to take an eternity while the next ones seem to pass in the blink of an eye?
|
As your brain recognizes patterns it starts to automate the processes of going through those motions and relegates that experience to the subconscious unless something new pops up. So the older you get, the more you're very accustomed to your life and the less you're aware of. On the one hand it makes it seem like your life is speeding up faster and faster, on the other hand it gives your conscious mind more space to look for the grander things in life instead of being caught up in the minutiae. Personally, I practice meditation every day, in part to help train my brain to pay closer attention to the details instead of glossing them over, since I've come to the realization that it's exactly the details that is the heart of my life passing me by.

Why are coins historically round? Seems like square coins would be more efficient/easier to cut from a sheet of metal.
|
coins are stamped not cut, a circle was easier to stamp. Later it's all about make counterfeit coins harder to make by adding dots, lips and etching. Each thing ups the price of the initial equipment required reducing forgers", 'Historically coins were made by getting some metal and putting it between two die with the reverse of the design that was wanted. This was then struck so as to imprint the coin. The naturally pushes the metal out a little. Having a round coin keeps this even where as a square coin would warp it unevenly. A round coin also has the advantage of slowly rubbing down evenly around the outside where as a square coin would be prone to wearing away at the cornersThey were not originally cut from sheet metal. They were stamped. If you watch GoT or medieval era films you will see people deal envelopes with a pool of wax and a stamp. Coins were made in a similar way.
