Why did our mother cat start hating her kittens after they grew up?
|
It might be because they don't appreciate the hard work and career sacrifices she's put into raising them. She could have been sleeping like 90% of that time but instead she was only sleeping 89% of it! You know what?!, they can just go live on their own for all she cares! Maybe when they grow up and have kittens of their own, they'll know what it's like to only sleep 89% of the time!

If Water is just H2O, how come we can't just create a bunch of water in a lab from the abundant elements of Hydrogen and Oxygen?
|
If you have a lot of hydrogen laying around, sure you can create water by just burning it. But where are you gonna get hydrogen in that amount?

Why was Nixon forced to resign after spying on his political opponents, but Obama has faced no repercussions for spying on the American public?
|
I can't believe it hasn't been brought up here yet: What Nixon did was illegal. He ordered people to break into a locked building and steal documents, then he lied about it under oath. Obama's spying program is totally legal under the PATRIOT act and several other laws and ruling produced in secret courts and congressional sessions.Nixon resigned because of mounting political and public pressure. Not because he was forced.

Why is it that when pressing on my belly button in a particular way I'll feel a tingling sensation in my urethra?
|
To your second question, I'm pretty sure about half the readers just poked their belly button.I feel it in my taint and anus when I get poked in the belly button. It feels like a low level electrical current shooting uncomfortable little shocks all over my insides.Great question. I've wondered this for years. The top comment is good, but I want more information, like WHY?

How are companies able to lower the costs of items on Black Friday?
|
The ads for stuff like steeply discounted TVs, PlayStations, etc etc are loss leaders. The store will take the loss but is hoping you will come in for the promotional purchase and stay to buy their overpriced holiday decorations, clothing, appliances, food, fragrance sets and other items not marked down .

Is there a reason why it's so hard to run in dreams?
|
dreams? What's that? I just close my eyes, two seconds later it's morning. Sounds like a hippie thing.I thought it had something to do with the spinal cord handling a chunk of walking, almost "autonomously" from the brain. That is, the brain "directs" in broad terms , but the spinal cords handles the nitty-gritty details of gait and related things. So when you're asleep, that part isn't responding to the brain at all, and your brain doesn't *really* know how to make the legs go correctly Note: I am not an expert in this area by any means **Edit**: _URL_2_', "I have very vivid dreams and most of the time I have a lot of control, it's pretty much like being Neo in the matrix, I've sort of trained my thoughts so that I can run faster, but in my dreams it's a completely different way of running, it's hard to explain. It was tough when I was first dreaming, but since I constantly dream I know what I can do and how to go about doing certain things, I'm basically breaking my dream rules. It's not all the time but I do feel like I have a lot more control over my dreams when I do have them.

- Why do women, generally, grow their hair long and men keep their's short?
|
It's been a while since I read about it, but I'm pretty sure the reason that men kept their hair short due to military restrictions during the roman empire. It was a standard procedure for them to cut all enlisted soldiers hair so it couldn't be grabbed in combat and used against them. I think because of this, the opposite became associated with women and that is why women are thought of as having long hair and Men are thought of as having short.

Why do we constantly complain about water running out, doesn't water just cycle?
|
The cycle have a rate. There is a certain amount of water per year of water that evaporate, condense and rain back down. In addition, not all the water that rain down is consumable. Some rain on the ocean where is become salty. Some drop on the ground, where it can reach a lake, but some also go in the ground and it could take a lot of times before that water reach an aquifer from where we could take it back to the surface to drink it. As long as we consume water at a lesser rate than the cycle, we are good. But currently we are consuming it faster, meaning the total amount of water available for consumption is dropping. See picture of the colorado river or the Lake Chard. Of course, we are not running of water. What we are running out if drinkable water in lake and river. We could always use water from the ocean, but that cost a lot more to remove the salt out of it and it wouldn't help population far from the Ocean, who would have to pay even more to transport water to them. Most cities were built where the water was.

Why do we make cars that go way faster than the top speed limit?
|
Because people buy them. This thread contains responses mentioning towing, and different speed limits, and all sorts of things that auto makers don't really care about. They're a business. They sell cars. The only reason they do anything is because someone will pay them to do it. They don't really care about how fast a car goes - they only make a car go fast because it makes them money. That racing team? Yeah, that's just marketing and research they do in order to sell more cars. They make trucks that are good at towing because they want to sell cars to people who need to tow things. They make cars with good fuel economy because they want to sell cars to people who care about fuel economy. Businesses aren't driven by some inherit desire to make a particular product or make it in a certain manner or with certain features. They're driven to make money, and car companies have found that be specializing at making cars, they can do that. If everybody stopped buying blue cars, no manufacturer would make blue cars. If everybody stopped buying fast cars, no manufacturer would make fast cars. If everybody stopped buying Ferraris, Ferrari would stop making cars.

Why are chemical weapons considered particularly heinous?
|
in addition to what others have said keep in mind it is REALLY hard to make nuclear weapons and even then they are hard to transport/use plus hey most of the nations who have them are strong enough that you can't really punish them this is in comparison to anyone/any nation who can throw together chemical weapons. It isn't hard to make a crude mustard gas and then they are pretty easy to transport. Now mustard gas is actually quite 'low' on the harm caused if dispersed over an area but it ends up causing mass long term harm while the less 'tame' ones are far worse, along with biological weapons. Well pretty much if it wasn't for the CDC there would be little/nothing you could do to stop it before massive harm. Nuclear weapons you can leave the area and assuming you haven't become so irradiated that you are essentially a Chernobyl diver you can be treated. Chemical weapons often do immediate irreparable harm and biological weapons actually punish the population if people run away

why do people have to pay for bee removal when bees are worth a lot of money?

how a shark like the Greenland shark posted to r/science can survive at over 9000 feet below the ocean surface, but things made of steel could get crushed.
|
[Link for the lazy.] For animals that live at that depth, every cell in their body evolved to survive at that depth. Basically, they're born there and they're used to it. Not everything that was made on land will collapse when diving to a great depth. Submarines and other devices can be engineered to withstand the pressure to a certain depth, which is how the video came about.So what happens when you bring this shark up to the surface? Will it fall apart from the lower pressure?
|
Does an elevated heart rate from playing intense video games count as cardio?
|
Cardio is conditioning your body to have more endurance when performing physical activities - your lungs improve, allowing more oxygen into the bloodstream, your heart improves, getting that oxygen to from your lungs to your muscles, and your muscles use that additional oxygen to more easily so the work. Your heart rate increasing due to excitement is the fight-or-flight reflex priming your muscles in anticipation of doing work, by making the existing oxygen more available. But you're missing the lungs bringing in more oxygen, and your muscles having a need for it.

why do so many people enjoy modern ultra-realistic computer games simulating horrible things like war and murder?
|
The same reason we have ultra-realistic simulations of car racing or flying space ships. People want to feel like they're doing exciting things they can't do in real life .Your question was actually "why do people like things that I don't like?" Do you actually need an answer to that question?', "The same reason that people have watched and read about similar acts throughout human history. Movies, books, plays, even sacred holy texts have all had depictions of violence. Video games are no different. If it doesn't appeal to you, great! It doesn't have to. Same way pickles do not appeal to me.

Why do we continue using the existing credit card technology over all these years despite them being so prone to digital theft and insecure?
|
I install pos systems and develop payment gateways. Two giant issues .merchant processing companies decide what equipment they sell to clients . either the company or the client has to foot the bill for upgrades to the new standard . so any implementation is slow . other countries have NFC, chip based cards for decades now. Apple pay is giving the final kick in the ads for major overhauls. Second, better standards and pin pads passwords exist and are being rolled out now. Mobile pay fits your criteria . installs of new units are occurring everyday. Third, credit cards will revoke fraud charges or call you up for suspicious transactions . if you dump $1080 in a day, you'll get a call. You can have text notifications for every purchase made .maes it really easy to identify fraud.

How does entropy prove why time only goes forwards?
|
Entropy is the gradual decline of the universe from order into disorder. It's irreversible, too; any energy we spend to create order in one area will inevitably create disorder in another area. The only way it would be possible to reverse the effects of entropy would be to reverse the flow of time.

What exactly is a time share, and why is it so bad?
|
A time share can be good, and I've known a couple of people who are happy with their decision. However, it seems most people are not. First: the sales pitches are legendary. These guys put used car salesmen to shame. Read some accounts online and you'll be amazed at the tactics. Second: these days, most people like to go different places on vacation. The time share location may become boring after the third year. Most networks will have a transfer policy, where you can trade in your week for someone else's somewhere else, however, there are usually additional costs associated with this. If you know for sure you'll want to return to the same place year after year , then this may be ok. Third: They're difficult to get rid of. Ownership is legit and it is considered an asset. There are costs associated with owning the asset. If you no longer want it, you have to sell it, but it's almost impossible to sell a timeshare as a private individual. Search around and you'll see people literally giving away their timeshares for free because they don't want them anymore. Fourth: the costs can make timeshares a very poor investment. When you add in taxes, maintenance, fees, transfer costs, and everything else, you could end up paying more annually than you would to stay in a hotel for a week. And that's on top of the initial investment. Bottom line: stay away!

The Taliban just killed 130 people in a school, mostly children. Why is that somehow part of a rational strategy for them? How do they justify that to themselves?
|
Terrorists have their own strategies, which are hard for most people to comprehend but nonetheless contain a coherent logic. Terrorism is an asymmetric tactic used by small groups towards two complementary goals. First it instills fear in those who support the government and/or a certain political ideology. Second it erodes the corner stone of a state's sovereignty, which is its monopoly of violence. If a government is unable to guarantee the security of its own people, then the populace begins to loose trust in it and the fabric of the state will begin to unravel. Terrorist groups can then take advantage of the resulting chaos to make territorial gains or even take over a country outright. According to their own calculus the legitimacy of the targets they choose is irrelevant. The more deplorable and indiscriminate the violence, the more publicity their actions gain and the more people begin to turn against the state. You have to remember that the majority of terrorism occurs in weak or failing states where large segments of the population are generally disenfranchised and already predisposed to viewing their ruling institutions as illegitimate. The Taliban chose their target because it conformed to these basic goals of terrorism. They killed a large number of children of Pakistan's military personnel adjacent to a major army installation. It is an act that strikes fear into the supporters of Pakistan's government and casts serious doubt on its ability to control its own territory and defend its citizens.

If I hypothetically built a fully functioning rocket and were able to fund the trip myself, would it be legal for me to leave earth?
|
I imagine you'd need FAA approval if launching in the US and other approvals that the likes of SpaceX and Virgin Galactic have or are in the process of obtaining relating to manned flight.A lot of it would be in relation to public safety that you aren't going to accidentally hit a plane and so forth.So yeah if you have enough money you can build your rocket and get govt approval. But you need amounts of money that generally only large corporations and governments have access to.
|
why do Diesel engines last longer or have the reputation of lasting longer than gas engines?
|
Diesel engines generally have high compression ratios and so are built to be stronger. That combined with diesel itself, as a fuel, being 'dirtier' in that when burning it you are effectively lubricating the valves etc as it runs.
|
why did the football commissioner got booed while holding the super bowl cup?
|
He's not very popular right about now, especially in New England. Tougher sanctions for allegedly deflating footballs than for players guilty of domestic violence, or simply trying to cripple opposing players on the field.
|
How are tattoos permanent if every cell in your body is replaced every 7 - 10 years?
|
You have to also realise that your body is not just directly made up of cells. You also have an extracellular matrix or ECM which is spaces between cells, connective tissues and fluids. This will mostly be where the ink sits. Tattoo inks are large molecules which your body can't get rid off on its own. In tattoo removal, lasers will break up the ink molecule allowing your immune system to remove it.Other users have correctly pointed out that the ink does not sit inside the actual cells. Your innate immune system cells do respond to the ink and "comsume" ink particles. As the ink cannot be destroyed, the cells die and the ink stays where it is *mostly*. The continual attempted degradation of the foreign material results in the ink particles drifting slightly over time; that is why tattoos fade and blur over the years.

How do Jeopardy contestants seem to know such a wide array of miscellaneous topics?
|
They study and learn memory tricks. The correct response on most Jeopardy questions is usually something that the average person has heard of or knows something about. The difficulty is that the clue is given using hints that aren't as common knowledge and don't mention the fact that everyone knows.
|
Why are there so many talented musicians on YouTube who can sing amazing acoustic song covers that never get picked up?
|
Because singing isn't hard. American Idol would have ran out of contestants by now if singing was actually a talent. So, since countless people can sing, it comes down to marketing. Who's going to get marketed? The person with the best connected parents or the person who can suck cock the best. Pretty simple.

in the world of adblockers how are websites still earning money by ads.
|
I cant explain all the technicalities. I run adblockers on everything though and still get a lot of ads. Depending on the website, i'd say the adblocker only catches about 1/3 to 1/2 the ads. The great thing about the adblocker is it seems to catch the annoying popup/overlay ads. I dont really mind small sidebar ads. There are also clickbait sites where the ad is basically part of the webpage and the site owner gets paid per click. The ones that have things like top ten lists and you have to click ten times to see the ten items.

How America can sustain copeous amounts of debt. But Greece went on the verge of economic collapse due to a small fraction of that debt?
|
For the same reason a credit card debt of 1000 dollars is a huge debt for someone who only makes 100 dollars a year, and it is nothing to someone who makes 10,000 dollars a year. The USA has a much bigger economy than Greece and earns much more. Additionally, the USA also has the advantage of being in control of their own monetary policy and coin. Greece, however, is part of the European Union and doesn't have that level of control. That limits the amount of things Greece can do to improve its own economy, while the USA has more options should things ever go south.

Am I legally allowed to build a spaceship and launch into space?
|
Space isn't owned by anyone, and once you're there you'd be free to do or go whatever or wherever you wanted. However, depending on where you're launching from, you have to go through some country's airspace to get there, and that airspace is likely heavily regulated. This means you'd have to get clearance from that country's government in order to launch.You need FAA approval for commercial and high altitude airspace. But spacecraft can be just a weather balloon. If you mean a fueled rocket, you would need permits for building a rocked sized bomb and the fuel for that rocket sized bomb. Hazardous material permits for that quantity are very much red taped

Before toilet paper was invented, what was the main source of cleaning oneself and how bad was hygiene?
|
Washing yourself clean after a bowel movement makes sense to me if you use soap and water. But water, unless it is high pressure which I'm assuming won't be the case, doesn't feel like enough to make you clean. I agree that soap and water will be cleaner than toilet paper. But just water feels totally inadequate to me. Can anyone explain.Water? In my country, for generations, we use flexible hose and attach it to pipe head / faucetHave you heard of water? People wash down there too. Long before toilet paper.Indians still don't use toilet paper usually. They have a cup/container filled with water and they drip feed it via the crack between your balls and your thigh which leads to your ass crack. Then with other hand they clean while feeding water. After they're done, the hand and ass crack is most times visibly shit free but obviously you gotta wash/scrub the shit out of it afterwards with soap.

Why do rich or famous people often get more lenient sentences? Shouldn't they be sentenced to the letter of the law, no matter how good their lawyer is?
|
Some good answers but you shouldn't look at it like rich people are not sentenced to the letter of the law, but that poor people get too harsh of sentences. The same law/reason that a rich person faces a lessor sentence exists for poor people, but their attorneys don't find it or argue it successfully. So when the prosecution or police officer makes a mistake, infringes a right, obtains evidence illegally, makes a bad argument, the good lawyer that the rich person has catches it, calls them on it and obtains justice for their client. The attorney that a poor person has doesn't do this. So poor people get screwed, but it's not because of the law but rather that the prosecutor and law enforcement got away with something that a better attorney would've caught and not let happen. As has been pointed out, better could be better for any number of reasons, some of which is obviously time to prepare and number of people defending.

If any of us would be teleported to the past, say circa 1500, would we cause a major technological or scientifical breakthrough?
|
If you sent me back that far i'd probably be very, very useful for knowing military strategy and such. Even things that seem common sense nowadays would be revolutionary to some medieval militaries. However i guess this is assuming that they even listen to me since i'd literally be some random pleb talking about what would sound like utter nonsense. Medicine would obviously be a big deal too, but considering i don't think you said we could research stuff before we went, sadly i have no idea how to make anti-bacterial soap or anything.

What would happen if you remove all the other planets from our Solar System and kept only Earth, Moon and Sun in it? Will Earth survive?
|
Now that the paths have been cleared, it's somewhat likely that gravitational tugs on Kuiper Belt objects by the gas giants could destabilize KBO orbits and send them in toward Earth. It could be better going forward without them there, but Earth may have turned out differently if not for the presence of the gas giants. [This article] alludes to a study that showed that Jupiter offers no protection at all, and answers at least part of your question: What would happen if Jupiter wasn't there?

How did a Boeing 787 travel faster than Mach 1 this week?
|
It didn't. There are 2 things to remember. The first is that the speed of sound is not constant, but changes with altitude and humidity. The higher you fly, the lower the speed of sound is. The second is that there's a difference between ground speed and air speed. Ground speed, which is the speed the article listed, is exactly what it sounds like; the speed of the aircraft over the ground, but that doesn't tell the whole story. There's also airspeed, which is the speed of the aircraft moving through the air. A plane flying due East at 500mph airspeed with a 100mph tailwind has a ground speed of 600mph. If it has a 100mph headwind, it has a groundspeed of 400mph. Airspeed is what determines mach number, not ground speed. The flight in question, NAX7014, spend most of it's cruise at 39,000 or 40,000 feet, where mach 1 is around 660 mph *ground speed*. Unfortunately I can't find flight data for the particular flight's recorded air speed or what the wind conditions were, but I can tell you for absolutely certainty that it's airspeed was below mach 1. The 787-9 has a standard cruise speed of mach 0.85 and a maximum cruise speed of mach 0.90.

why have humans evolved to only be required to consume such a small percentage of their body weight daily relative to some other animals on earth?
|
The same reason you LOVE the taste of sugary and fatty foods. Humans have evolved to eat a small amount of very high energy food - like others have said, we even go to great lengths to cook it first so it takes less energy to digest. Fats and sugars are very dense in terms of energy, as are most of the other carbohydrates we eat - think about your favourite foods and you'll probably admit they're sugary and/or fatty. Modern humans eat even less because we don't have to go out and catch the pig or grow the sugar cane ourselves. We generally don't really do a lot so we don't need to eat a lot.Some animals , at 10%) that consume "x percentage of their body weight" in food are eating foods that aren't nutritionally dense. Others , at over 100%) are consuming nutritionally dense/available foods, but have an extremely high metabolic rate and output. Most humans consume nutritionally dense foods and have relatively low metabolic rate/output, thus food consumed as a percentage of body weight is low.
|
Why do people get so worked up about things that don't affect them?
|
To echo a point below , people without much going on place a lot of emphasis on things that most of us consider trivial. I think that everyone has to care about something, and if you don't have a traditional answer other things seem more important. My mom would always freak out when the house wasn't perfectly clean because that's the only thing she did all day. The rest of us didn't really care because we spent 10-12 hours on sports, school and work. Go ahead an disagree, but I would say the same thing about politics for a lot of people. They are uninvolved with other activities and interests, so they place a lot of stock in political belief and ideology. Take a step back and think about how frivolous, and quite frankly, pathetic, it is to get into a heated argument about politics when each person is no more involved in shaping policy than one vote. You are arguing about abstract ideals that often boil down to fundamental disagreements about the nature of society or people. I find politics interesting, but I respect those who disagree with me. In fact, I am moderately on the right and one of my best friends is a socialist and gay on the far left.Part of our sense of self, is that we are part of a group/tribe that shares the same values and beliefs that I do. People that are from a different group who do not think like me are the "enemy". Now whether or not we just ignore them, attempt to understand them, defend against them, or attack them depends on what we believe is at stake and how threatened we feel. If we feel our status or sense of self is being challenged, we may react more aggressively.

Why is it cheaper to buy in bulk?
|
There are two different fundamental reasons. One is that there are 'economies of scale' in packaging, logistics, paper-work, etc. The other is that buying in bulk means you have more bargaining power.
|
Why are we attracted to only certain people ? Why are some people considered ugly while some are considered attractive when basically everyone is just skin and hair?
|
I normally dislike anyone who doesn't look like they are in shape, mostly because I'm an active person and I want a partner who will be on the front line with me without complaining.When it comes to modern society at least, a basic way to judge beauty in almost every culture is symmetry. The more symmetrical a person is, the more "beautiful" they may be considered.Welcome to /r/nihilism Edit: Also, I've heard a lot of it has to do with symmetry.
|
Why is there a focus to raise min wage instead of creating more working class jobs?
|
Because creating or cutting jobs is the biggest steaming pile in politics. It's used to leverage huge amounts of wasted money and votes. The fact of the matter is that the economy makes jobs. If you focus legislation on prosperity and opportunity and keeping the economy healthy, jobs will come naturally. If more people have more buying power the economy will grow. So it's a much more effective boost to the economy to increase the opportunity and buying power of the people by large then to employ a limited number of individuals doing something that the market doesn't necessarily demand.Because minimum wages are determined by the government and most jobs are provided by private companies. While the government does have a lot of employees , they cannot force companies to hire more people.

How do old countries outside of the U.S. study their own history?
|
In England schools pick a selection of topics and teach those instead of trying to give everyone a broad overview. So the exact topics each person learns is different depending on the school, although there will definitely be something about the two world wars. We quite often get Americans asking what British children are taught about the American revolution, and the answer is they usually aren't taught about it at all. Out of all the things that could be taught, it usually doesn't make the cut. There are other things that are more significant to British history, and we can't teach it all. I didn't even learn about how the UK was formed, let alone the USA.In Australia, being a very young country, we study some of the highlights of Australian history in younger grades, then move onto World history in high schoolIn Poland history is a very important subject being taught at almost every level of education: In primary school we learn quickly about whole history, from the ancient Egyptian, Sumerian and Chinese civilizations to the end of Cold War with a focus on Poland ofc, its early stages, golden age, partitions, getting independce, WW2, being under communist rule etc. In middle school its basically the same, but we go through history much more thoroughly and stop at WW1. If you go to a typical high school you will repeat that process AGAIN, this time also focusing on issues in history, political systems, reasons of what and why happened etc. But I went to some kind of technical-specialist IT school where we get only continnuation of history in midlle school: WW1 to present time, also with a lot discussions about some issues and reasons why something happened ', "In the Netherlands there is more of a focus towards European history with some more focus on specific national topics . This process does take several years , depending on the country, school system and curriculum.

Can you please explain how a subpoena works in regards to being ordered to testify verses pleading the fifth amendment?
|
A subpoena forces someone to testify at a criminal or civil trial. The 5th amendment says that you don't have to testify or incriminate against yourself. Hypothetically say you witnessed a murder across the street while you were coincidentally buying illegal drugs. You could be forced to testify at the murder trial but then plead the 5th because just admitting you were at the drug house would be incriminating yourself of a crime. What the prosecutor would probably do is then give you immunity of the drug crime which would mean that you would have to testify as to what you saw regarding the murder.The fifth amendment protects you from incriminating yourself while testifying under oath. It does not provide you an out in regards to complying with a subpoena. If you do not respond to the subpoena, you may be held in contempt of court, with fines and possible jail time as a result.

in Hawaii, how did Spam become one of the staple foods to that island state?

Spam was shipped overseas with the US soldiers during WW2, you'll find most islands with a big US presence developed a taste for spam. It was just abundant and taste good because it's incredibly bad for you.

How can Pandas survive on a diet of 99% Bamboo while humans have to eat a diverse range of food?.
|
My understanding is that pandas hardly *thrive.* They've evolved into a kind of over-specialized dead-end. They are a dying species, and it isn't just because of humans destroying their habitat. Their caloric and nutritional demands are difficult to supply via the one thing they've evolved to eat. Birth rates for pandas are low, and infant mortality is high. Pandas are going the way of the dinosaurs. Humans are massively difersified. We can get our nutrients from a great many things that can be found almost anywhwere. As much as humans have threatened the food supply of the panda, we are also going to be the only hope for the species' long-term survival.
|
Why do we throw random medications at depression to see which will work?
|
Because medications aren't 'one size fits all'; depression specifically can be caused by different things and people react differently to different medications, so it's necessary to try a few before finding what will work in some cases.
|
Why a developing country like India have cheaper health care then developed country like America?
|
The economics of health care are complicated, especially when it comes to the United States, which has a rather unique position. Indians have less money, so demand is lower--prices must drop to accommodate this. On the other hand, the quality of care in India is also poorer, and fewer people have access to good care than in the U.S. Americans subsidize much of the world's drugs, because Americans pay a high price and collective schemes in Europe purchase them below cost. Besides care being more expense, Americans use more care than others, so that total expenditures get quite high. These trends are not iron rules, and aren't necessarily sustainable. For example, if reforms in the U.S. cause drug prices to lower, drug prices across Europe will go up.
|
When a corporation makes a profit, where does that money go?
|
Profit is not cash by the way. A corporation could make a ton of profit but be incredibly broke, it's how accounting works. So where does profit go? Nowhere. It's an accounting concept.In many of the larger corporations that profit goes to the shareholders who each get a very small amount per share. This may be the CEO/founder/some rich person who owns a bunch of shares, or it could be your grandpa who bought a few shares of coca-cola as part of his retirement plan.

|
Why do humans, for the most part, tend to find unhealthy foods more satisfying than food which is good for you?
|
Some food is common and some is hard to find. To motivate you to find the hard stuff that you need at least a little of, you are evolved to really like its taste But at the same time, you are evolved to mostly deal with a diet of the stuff that is easy to find. That way you survive on the easy stuff, but put in the energy to get the rare stuff that you also need. So you body runs best with a little bit of the rare stuff and mostly the common stuff. But you like mostly the rare stuff. So you like sweets and fat and protein, which are good for you in smaller amounts. Your body is designed to function best with a little of that but mostly vegetables. Now, all of a sudden, none if it is hard to get. You you really chow down on the stuff that used to be rare. You don't even have to eat the whole fruit. You can eat concentrated sugar. That is essentially a drug. While your body needs a small amount of it. What it mostly needs is the Kale and similar vegetables that were common and easier to get years ago.

Why is there a limit on how big animals/insects with exoskeletons can grow?
|
Insects breathe through their skin, allowing for only relatively small pores through which to obtain oxygen, meaning that there is a limit to how large, and therefore how much of a surface area/mass ratio the creature can support with the oxygen in the atmosphere. Since the Earth's atmosphere used to have more oxygen, arthropods could grow much larger, leading dragonflies over three feet long and the like. Like this: _URL_1_ I would cite sources, but I'm lazy. I'll find some if you really want them.

Why do some people deny that the holocaust ever happened, when there is proof that concentration camps existed ?
|
There's a very good and readable book by Michael Shermer, *Why People Believe Weird Things*. It deals not only with Holocaust Denial, but also conspiracy theories, UFO believers, creationism, and weird cults. Shermer, a former creationist, is partially writing from experience. The TL;DR is that weird beliefs result from a number of logical fallacies, the most pronounced of which is thinking in double negatives. It's not about proving *their own* argument to be correct, so much as finding fallacies in the opposing side. So errors in Darwin's account are chalked up as proof that evolution is wrong. A revision of the Auschwitz death count is evidence that the Holocaust didn't happen. Et cetera.It's fairly easy to deny evidence for something that you haven't directly witnessed. A great example of this is the [Bielefeld conspiracy], a fake conspiracy theory that states that the German town of Bielefeld doesn't exist. After all, have you been to Bielefeld? Have you met someone who has? For most people, the answer is no. Then how do you know Bielefeld actually exists? All the maps and pictures could be faked. Anyone who says "yes, I have been" is part of the conspiracy. This is the basic "logic" behind these things. Deny anything that opposes your personal conspiracy theory and put all contradictory evidence in the "part of the conspiracy" box.One conspiracy theory I've seen floating around here on Reddit and the rest of the Internet is that the Jews cooked up the whole Holocaust thing to garner worldwide sympathy so they could establish Israel as a country, and point to their suffering in the Holocaust as a rebuttal to any criticism. Most Holocaust deniers don't believe the *whole thing* was faked, just that the numbers and scale were exaggerated. but there are still people out there who say it didn't happen at all. The whole thing is just a straight up lie, they say, like Turkey denying the Armenian genocide.

Why can women have an abortion but the father be forced to play child support
|
I've seen this question before. It all boils down to which personal right the courts have decided is more important. In this case its the woman's right to autonomy of her own body. The guy has no say in what the lady chooses to do after copulation.Anything else would mean A: Women would be dragged kicking and screaming into abortion clinics, or B: Men can father as many children as they like without any consequencesThe father also has options . like giving up his parental rights. If that were to happen, he would no longer be financially responsible.

How is it that games like LoL and Dota are still basically hacker-free, while CoD games have hackers within hours after launch?
|
They are not hack free, the problem is that there is a big investment by the companies developing DotA and LoL to keep the problem mitigated. I'm not familiar with LoL but the way it works for Valve is simple, if you get caught running a hack they shut down your entire account, you lose all your purchased games. They also utilize a reporting system in-game, if a player gets reported enough they get put into a the low priority queue with other hackers and generally mean spirited players with long wait times to find matches. The only way to get out of the low priority queue is to stop being a douche.

the cleaning process of a surgery room
|
As spotless as they can. They actually don't really change all that much any differently than cleaning other rooms of the hospital: everything should be wiped down. There's no vacuums, at least not that I've seen in so far, but they do mop the floors and often times only have about 15 minutes between surgeries to clean the OR. One thing that can assist germs is the air systems that can be adjusted. The biggest thing is going to be the tool cleaning, which is a huge process in and of itself and has multiple stages. Unfortunately, hospital infections are more common than people think. No one likes to talk about them, but they do happen because sometimes the best isn't good enough when germs are everywhere. Not to say you should expect to get an infection if you go to the hospital, just that it does happen.Operating rooms are specifically designed to be as clean as possible by default. For example the air system would have decent filtration to limit outside contaminants and most of the surfaces will be non porous. Prior to surgery the OR would be cleaned to sub-sterile with damp mops or wet vacs and then essentially flooded with disinfectants to kill anything still remaining. During the procedure, traffic is minimized in and out of the room in addition to all the body substance isolation measures . And that's really it to my knowledge. The "final clean" wouldn't be any different than the regular cleaning.

What the hell symphony conductors actually do.
|
They are mainly there to ensure everyone stays coordinated. When you have dozens of musicians, even skilled ones, they can drift off time a bit. In addition they can emphasize certain instruments at different times to have them play louder/softer. In the sense of an interview show, Colbert can't really shake the hands of all those people so the conductor acts as the focal point.

why do games need a screen that say "press start"??
|
In the Olden Days, you'd go right form the Start to playing the game, and you needed a pause to make sure people are actually ready to play. You also wanted that pause between GAME OVER and the next game. In modern games it's probably a holdover from that. Game designers want some kind of loading screen with some kind of cool video and exciting music going on before you hit START and get to the menu that can take up large portions of the screen. You are also less likely to accidentally start/load/EXTRAS a game when you have to hit Start first.

What would happen if a person somehow slipped into a blue whale's blowhole?
|
Okay, let's throw in a hypothetical here, since the consensus is that the blowhole is too small to fit even a toddler. I am an anorexic dwarf midget with narrow bone disease, and I can in fact slide through a whale's blowhole. What happens?", 'I read the title as "butthole." Does that change the answer?', "Let's say you are on Ms. Frizzles Magic School bus and today the class is going into a whales blowhole. Well the good news is that you won't be digested because a whales respiratory system is not connected to their digestive system; they can't breath through their mouths like we can. The bad news is that you will likely die anyways. Basically you would end up in a naval cavity closer to the bottom of his head if you didn't get stuck in the tube from the blowhole. You would normally choke the whale by going down its airways but I guess through magic the school bus is tiny enough to not disturb the whales breathing. Here you would asphyxiate once the whale went underwater and closed off your access to oxygen.

With most countries so far in debt, how does China have all this money to loan other countries like the U.S. and U.K.
|
China doesn't actually own some huge quantity, relatively speaking, of US Treasuries. Last I checked it was something like 4% of the total. Our biggest creditor is ourselves, basically. Like $5.3T is owned by Social Security, another $5.1T owned by normal American individuals and corporations, and maybe $2.5T owned by the Federal Reserve. If China suddenly dumped every UST security on the market it would hurt us, but it would *devastate* them.That's because the money itself is loaned into existence. It's mathematically impossible to pay off the US national debt, there aren't enough dollars in the entire world. I encourage you to look up how the federal reserve creates money on YouTube, it's quite jarring. Why is this post controversial? It's factual and answers the guys question in a good "5 year old" answer.> ELI5: With most countries so far in debt, how does China have all this money to loan other countries like the U.S. and U.K. Well, every time there's a debt, there has to be a corresponding creditor. Having many countries with large debts would make it easier to maintain [a sovereign wealth fund for others].

Why do cookie dough packages say 'DO NOT EAT RAW COOKIE DOUGH', but everyone does anyways with no consequences?
|
Ok so I just did the math. According to the [CDC] The death rate of non-typhoidal Salmonella in the U.S. is 0.0375%. According to the [people that have the most to benefit from Salmonella infected eggs] one in 10,000 eggs has Salmonella, which is 0.01%. Combine those and your chances of dying from Salmonella from a single raw egg is 0.000375%. To put that in perspective 0.010345% of the population dies in auto accidents every year. So you're Almost 30x as likely to die in a car crash than to die by eating a raw egg. So go ahead, eat all the cookie dough you want, you're more likely to die by getting hit by a bus on the way back from the market.All packaged cookie dough is made with pasteurized eggs and is safe to eat raw unless you have a weakened immune system + hit the bad cookie dough lottery. Ice cream cookie dough is usually not made with eggs, as eggs are just there for baking and to add a little moisture to the dough. If not baking, the egg can be substituted with water, vegetable oil or milk. Home-made cookie dough is the most dangerous to eat, because the eggs you buy at the store are not pasteurized. Still very uncommon but more likely to get you sick than frozen cookie dough. Also the yolk of an egg is safe from salmonella, only the egg white needs to be cooked, which is why you can eat a sunny-side-up egg with raw yolk but cooked egg white. The salmonella is from the shell of the egg, which only the white touches and a barrier is formed between the white and the yolk. But even raw eggs are pretty damned safe. Higher chance of getting injured on the way driving to the grocery store to buy eggs, then by eating the eggs raw.

Why do religions use stories and analogies to explain values and teachings, instead of stating stating them directly, which leads to misinterpretation?
|
It's basic manipulation, You are far more likely to believe/follow something if you believe you reached the conclusion yourself.Well, the point of ELI5 is to use simple terms that a child can understand to explain an idea. Sometimes, ELI5s use stories or real life examples to illustrate an idea. I would imagine that the writers of the Bible are doing the same thing.When religions were young lots of people simply were not literate. You couldn't just go to a store, buy a notebook and jot everything down. Because of this some religions don't have any scriptures that date to their beginning. Cultures used to use poetry and stories to pass history down to one another. Of course simple stories could be exaggerated and some things just simply weren't explainable with the knowledge of the day, without explaining a higher being is influencing it, or using an analogy . This isn't the best explanation but hopefully it gives you some ideas of why religious books aren't written like a book of laws.

Adenosine is produced which leads to increased feeling of tiredness / need for sleep. Do sufferers of Insomnia struggle to produce this chemical or is there something else at work?
|
Insomnia more times then not is a symptom of anxiety. Insomniacs feel tiredness constantly. They just can't sleep.One additional factor at work can be the length of the internal circadian rhythm. This is sort of like your body reading out a very long complicated instruction manual which ideally takes 24 hours to read, and then restarting as soon as its read it. This is part of why you tend to get tired at roughly the same local time , and why you can feel a bit better in the day even if you didn't sleep at night. In some people with insomnia, this circadian rhythm can take a slightly different period of time , and this means you slowly get out of sync with society in general. I probably have an example of this - left to my own devices I tend to "drift" later and later into the day, often until I don't go to bed until sunriseMaybe off topic. One day I had an extra shot of coffee at starbucks..well, that might right before bed my heart went "thump!" Like a huge lump in my throat. Then it started to race, I went to the ER after about 15 minutes of that. They checked my heart rate at 224 bpm.I was immediately taken back to A room and given adenosine..it felt like my heart stopped for 3 seconds after that injection Then my heart went back to A normal rhythm. It was diagnosed as SVT. Anyway, that's my experience with adenosine

what's the purpose of having 87, 89, 91 type of gasoline?
|
Ok so theres already a few post of people explaining why but I'm gonna take another shot at it for your reading pleasure. Inside the engine are pistons and cylinders. ) If you were designing a car and you wanted it to go faster one of the things you could do was design it for *higher compression*. Higher compression is this: When the piston comes up in the cylinder it squeezes the fuel/air mixture tighter and puts it under more pressure. Why? Because a tighter squeeze means a bigger bang! Which = more power. The downside to this is when compression gets too high the fuel/air mixture can automatically ignite itself without the spark plug; this is bad because the timing of the explosion will be off and can cause damage and less performance. Higher octane fuel is based on fuels resistance to [preignite]. The higher the number the better that fuel is at resisting igniting itself under higher pressure Extra credit: Compression is normally rated in a X:1 ratio. Or, taking X units of volume and compressing them into 1 For example a 9:1 Compression ratio is taking 9 units of space and putting it into 1. Comparitively a 10:1 ratio would mean higher compression because you're trying to pack more in. Does that make sense? Picture it like this. You have a box and that you're trying to pack with springs. If you try to put 9 springs in a box the lid will try to push open on you. Now if you try to put 10 or 11 springs in a box the little with push harder! And thats where it all makes sense to you OP

Why is there such an embarrassment regarding sex and nudity among the majority of people?
|
I think it's largely because sexuality has always had pretty important implications, namely children. There have always been some forms of birth control, even in ancient times, but nothing like today. Oftentimes, the only real means of birth control was preventing sex altogether. If you did look back a couple of centuries or more, there were no truly effective means of treating STDs or testing for paternity or attaining child support. Even then, raising a family was much harder and more expensive than it is today. A woman who did get pregnant outside of marriage was in for a very difficult life, and not just from the stigma. There were no real social services to help her and she was at a huge disadvantage in the physical labor intensive economy. I think the society and people of those times had good reasons to develop a culture that restricted sex to marriage, with some negative consequences. We are very fortunate to live in a time where we can enjoy sexuality without nearly as many negative consequences.

How do people who live up north get through the cold?
|
1. Its cold for us too, we just have grown accustomed to it so know that certain times of the year require thicker clothes, jackets, boots etc.. 2. Our municipal systems are designed to take winter weather into account salt trucks, snow plows etc are all part of city planning budgets. This year has been ridiculously cold and some areas have been shut down by excessive snow/ice/winds knocking out power, making roads inaccessible. However, this isn't the year over year norm and a few inches of snow now and then and really cold temperatures aren't terrible city closing events

How come water will break your phone, and how do companies make the phone completely water proof?
|
Your phone contains a printed circuit board. Basically a piece of silicon with wires embedded in it. When water gets on this board electrical connections can be created between two of those wires that were never meant to touch. This can wreak all sorts of havoc on your phone. That's why they tell you to remove the battery and keep it off until it dries out. Edit -fixed typo

Why isn't bread soggy when frozen and then thawed out?
|
There's no water in the bread when you freeze it. Thus it's not accumulating ice. Your just cooling the bread itself down really cold them worming it back up. Thus there is not water involved.Unless it is soggy when you freeze it, why would it become soggy when thawing it? The water content is the same. The thawing process is rather slow if you just leave it out, any excess moisture gained by for instance ripe from the air will evaporate before it can do much soggy-ing.

It is an useful measure to determine how much a person or enterprise is worth. People with high net worth are called high net worth individuals and often employ wealth managers and investment counsellors to help them manage and grow their wealth by recommending the best investments, acquisitions etc.

Why don't some museums or fancy churches allow flash photography?
|
It's disruptive to the people enjoying the space", 'I was a tour guide at various museums and basically you are allowed to take pictures, just not with the flash as the other redditor pointed out, it can damage some of the paintings also oil paints will naturally fade over time and the flash accelerates this as almost everything but raw umber is known as a "fugitive" colour, and that's why most oil paintings have that brown tone to it, as that's the only colour that will keep its vibrancy over the years. When our gallery would let fellow students take pictures, its because we were the only ones let in and no one else was around to see us doing it :p I think if that was widely known there 'd be a lot more accidental flashes occurring and the museum doesn't want to risk it. I just wanted to post my comment because I thought that was mind blowing the myth prevailed of no pictures at all in museums of art or history, and take pictures wherever I go anyway :Pi just write down the names of what i like and google later. museums are already annoying with people enough. quiet reverence is important as nobody is really there to see each other. my least favourite is when there are headphone audio tours and the majority of people are shuffling like crabs along the wall in a queue when you are just going about as you pleasePretty much all the reasons have been stated but there could be health and safety concerns. I have a friend who has epilepsy and she prefers going to cirtain museums and galleries because flash photography is not allowed.

If the people that went over to treat Ebola victims were wearing air tight suits to prevent them from getting the virus, how did they get Ebola?

The suits are helpful to keep away infection. But, they can't be worn 24/7 so all it takes is contamination when they eat, go to the restroom, or anytime not in the suit. Because Ebola takes several days to show symptoms, people can get it before they know anyone near them is sick.

What exactly is the Large Hadron Collider and what does it do?
|
The LHC is a storage ring with two counter-rotating beams of particles. The LHC is capable of developing beams of protons and lead-208 nuclei, so they can collide protons with protons, protons with lead-208, and lead-208 with lead-208. The proton-proton collisions are used for things like producing Higgs bosons. The proton-lead and lead-lead collisions are used to study nuclear matter under extreme conditions, quark-gluon plasmas, etc. The ring itself consists of a [repetitive pattern of magnets] that steer the beam in its circular path, and keep it focused so that particles aren't lost by running into the walls of the vacuum chamber. The magnetic fields are produced by running electrical currents through coils made of superconductor.

Why is it bad to end a story with, "And it was all just a dream"?
|
It's lazy. Think of any book or movie you've ever seen, and add a person walking up at the end. If the story was any good it would've had a strong enough end to finish without it. That said, it can be useful. Alice in Wonderland is one example, where waking from the dream links Alice back to the real world after standing up to the Queen. Some would say an example of bad use of the dream ending is The Wizard of Oz. The key is that the dream world is assumed to no longer exist when the character wakes up; the character needs to take something out of the dream like Alice, as opposed to doing things for the non-existent people within the dream like Dorothy.Because it is done too many times and it will not have the desired effect. At least if you do it straight up. Inception manage to do almost the same thing and be awesome at the same time. I 've noticed that an art work is as good as its balance between "being something new that you didn't know/have seen" and "be understandable enough to not lose you".

Why did it take so long for anyone to figure out how to draw in perspective? Why was that so difficult?
|
This is a complex question! And it has several indirect answers. First, I work as a designer, painter hobbyist, studied art history at university, traveled extensively and have visited almost all named galleries in Europe except for Russia. First, early Japanese and Indian artists did draw in perspective before European early renaissance artists developed rules of perspective. But, certainly Japanese perspective used a ~30° isometric for reasons I don't know as I never studied Japanese art, it seems they were painting isometric scenes centuries before western artists. Same with Indian artists. Second is the subject. Indian and Japanese artists were painting battle scenes, household domestic scenes and landscapes. Indian Hindu artists had many God figures with direct interaction with human figures so could naturally develop scenes somewhat unique to different artists telling whatever story. Indian Mughal emperors were notoriously lackadaisical about some aspects of Islam so their artists painted the same battle, domestic and landscape scenes. There's also the fascinating history of Japanese temple geometry [Sangaku!]: it's too long to describe, but they basically solved most geometry problems visually centuries before Pythagoras came along, so that affected the artists capabilities. Third, European artists came out of the manuscript illustration by monks: small biblical scenes, isolated, sprayed across a page. No real need to develop a perspective based scene. They also painted the alter saints iconography, same scenario. When scene based art started biblical scenes dictated Jesus, Mary or the cross were the central icon and slowly 1 point perspective developed. Then, to compact several centuries, 1 point naturally flowed into 2, 3 and false point perspective as just more artists got better by practice and the apprenticeship system. Also, a few artists in the early renaissance like Ucello did extreme studies of perspective drawing CAD image wire frame perspectives of objects.

I've had several scars from surgery and accidents, but every time I get injured, it results in a scar.I think the scar is determined by the depth of the cut. Not by how well the scab forms/heals.

Arrests of FIFA officials in Zurich

Why is salt water so difficult to make drinkable/usable?
|
It isn't difficult so much as impractical. Extracting salt from water take a lot of energy. The simplest way it to distill the water, while the more complicated but less energy intensive reverse osmosis is becoming more common. But both are quite expensive. The more serious obstacle is distributing the water. Most of the world's water distribution network is driven by gravity. Water from uphill flows downhill and is diverted to where it is needed. Desalination gets you a bunch of water at sea level, which is about as downhill as you can get, and leaves you with the expensive problem of how to get the water to where it is needed.

Why do some organs come in pairs, like Kidneys and Lungs, but others are singular, such as the Liver or Heart?
|
I think part of it might be the ratio of volume:surface area. If a system is too large it becomes inefficient in terms of diffusion. Having two smaller kidneys is likely more efficient than one big kidney. My other thought is that two small organs are easier to fit in the limited space our torso provides. It's the difference between trying to fill a glass with sand versus filling a glass with alphabet blocks. Sand obviously uses the space more efficiently.Increasing surface area has a larger impact on the kidneys and lungs than other organs because they work largely through diffusion. Having pairs of these organs probably yields a substantially higher benefit than having a pair of, say, livers or hearts which would not benefit AS MUCH but would "cost" substantially more in terms of resources. I'm about to finish my BS in biology and this is my best guess.Two organs with stuff filtered through them equally are easy to make. This also provides a backup whatever in case one of the organs is messed up.Two hearts, however, would be bad for an organism, because one heart wouldn't be able to work as well by itself after after working its life at 1/2 the power of the heart we have today. The heart is also less likely to fail than other organs- blood clots and stuff make up most heart problems. So if you were an evolved man with two hearts, they wouldn't help very much against heart attacks or other similar problems, and you'd be dead anyways if something happened to puncture or rip your heart , which is one reason why double organs work in the first place. Tl;dr: One kidney filtering for another would work fine, but one heqrt failing and leaving the other at 1/2 power wouldn't work at all. Heart attacks and heart disease would still be as common. Doublehearts just wouldn't work.

What are the anti-EU parties across Europe actually objecting to?
|
It is mostly to 'Regain control of individual countries' For example, UKIP want out of the EU due to several things such as immigration, millions spent bailing the EU, EU superstate, single currency etc There are a number of reasons why leaving the EU *would* benefit the country, especially one as developed as the UK or France. However it also eliminates the trade markets, freedom of movement and many of the EU laws we actually benefit from. It would make the cost of living skyrocket and make travel a lot harder than it should be. In all, it isnt a good thing to want out of the EU, as it leaves us in the open ready to be swallowed by the likes of china, russia or america.Anti-EU party hopes and believes that EU will become worse in the future. If we ask anti-EU parties: "what is bothering you about the EU", they will just list every bad thing about EU that they can come up with. If the list is long, then the anti-EU party is happy. A political party is supposed to have some opinions and plans, and EU says it has some opinions and plans, if the opinions and plans are different, then the party and the EU are supposed to be enemies, right?

Why do many archaeological finds in ancient cities/countries such as Rome or Egypt appear to have been "frozen in time"?
|
Civilizations aren't typically abandoned. Many world cities are built on the same land where ancient people decided to gather together. Some archaeological sites reflect a catastrophic event that resulted in the abandonment of a community These places may not have cleaned up afterward because there was no one left.

Why did contact with the Vikings not have the same effect on Native American population that contact with Europeans at a later date did?
|
Europeans don't innately carry diseases - the Columbian Era Europeans were leaving crowed & unclean cities, crammed into crowed boats with livestock for 3 months. All it takes is one sick person to get on board and everyone else is at risk. Escaped pigs from Spanish explorers probably spread diseases quicker than humans. The vikings were traveling comparatively short distances from Greenland, probably with no livestock. Trade routes may have been more connected further South compared to Newfoundland, so disease spreads quicker with sustained contact.

Why do we have to go to such great lengths to take care of oral hygiene in ways our evolutionary ancestors never did?
|
I'm pretty sure your premise is false. Ancient Egyptians, for example, did pretty remarkable dental and oral surgery.
