How does sharing a facebook post help the person who posted it?
|
Er people like to think that others care about the stuff that they post. The fact that people like/share it shows that I guess? It's validation from others and adds to their self-esteem. Very toxic in nature though, when people rely on it to fuel their self confidence. IMO I find it really really pointless and sometimes annoying. I mean sure, there are posts that are really worth sharing, but most of the times people share redundant things. Look, I get that Facebook is a social media platform, but it feels more like a site for people to garner attention for themselves.

how do companies like Amazon buy consumer products to resell and still make profit?
|
They most likely make a deal with say Sony to sell a TV. We'll say the TV only really costs Sony $500/unit to produce. Sony will say that they will sell that TV to Best Buy for $800/unit. Best Buy retails that TV for $1,200/unit. Best Buy gets that price from Sony because they will tell Sony that each quarter they are going to buy 10,000 units to sell in its stores and online. Amazon comes in and says we're going to buy that same exact model of TV as Best Buy, except at a rate of 25,000 units/quarter. So they are going to get a price from Sony for say $600/unit. And here's the best part, Amazon isn't even going to stick that item, they are going to have it drop shipped from Sony directly to you. So because Amazon has no real overhead on that TV they are going to sell it for $800/unit. They'll make $200/unit for just being the middle man to process your order. Best Buy on the other hand has a ton of overhead for selling products. Yes they both have warehouse space and pickers at those warehouses, but Amazon doesn't have brick and mortar stores. So that's an additional 25,000 less employees it has to pay, an additional overhead for 2,000 retail stores that has to be baked into the price of every single item. Let me know if I am totally off base of not.

why can't I donate blood if I had hepatitis B
|
While this happened a long time ago, and in all likelihood, you are now free of Hepatitis B, blood banks don't want to take the risk that they may infect someone else with hepatitis B. The nature of viruses is that they are very hardy. Just because you don't have symptoms doesn't mean that you aren't still infected. If you are still infected, the reason you don't have symptoms is because your immune system is controlling the spread of the virus and preventing symptoms. However, consider this example: If you were to donate blood, and that blood sample happened to be contaminated with Hep B, and that contaminated sample went to an anemic cancer patient . That patient would have liver failure in no time because that patient would not be able to fight off the Hepatitis B infection. The overall point of this example is to emphasize that it isn't worth the risk for the blood banks.

What's the difference between regular gas and premium gas?
|
The difference is the octane ratings. Premium gas has a higher octane rating. The higher the octane rating the less likely the fuel is to ignite under heat and pressure. When your engine is running very hot and hard sometimes the fuel ignites before the spark lights, this is very bad because the fuel is burning when the piston is moving upwards. Premium fuel does not last longer because your car's computer will inject the same amount of fuel.Regular gas has a lower octane level than premium gas. Engines that have higher compression ratios in the cylinder bore need higher octane to run smooth and prevent damage to the reciprocating parts.

How does what we eat and drink eventually become so much different stuff like skin, brain cells, hormones etc.? Are our fingernails really just remnants of dinners gone by?
|
What we eat is essentially building blocks for our body. When we digest the food, our body breaks the pieces apart into individual blocks. Our body then reassembles the building blocks in a different order to create the parts it needs. Some of the food is used as energy for this reassembly to occur. But yes, you are essentially made out of the food that you eatBasically all the food we eat consists of the raw materials the body needs to form new cells and tissues. These raw materials, however, are packaged up into things like proteins and complex carbohydrates. Our bodies digestive system breaks down these materials into compounds small enough for it to use in numerous functions. The mouth physically breaks apart food and saliva begins digestion of carbohydrates. The stomach physically and chemically breaks down food yet again. The small intestine digests proteins into smaller proteins or amino acids. Further down the small intestine and in the large intestine, all the food has been broken down into small enough compounds to be absorbed into the blood stream. The compounds then travel in the blood stream to numerous locations in the body to either be used immediately or stored for future use.

What is the no true scotsman theory?
|
It's where you make a statement, and someone finds an exception to what you just said, and so you come up with a non-reason why the exception doesn't count. [Wikipedia] gives this example: Person A: "No Scotsman puts sugar on his porridge." Person B: "But my uncle Angus likes sugar with his porridge." Person A: "Ah yes, but no *true* Scotsman puts sugar on his porridge." It's a kind of circular reasoning. The example of Uncle Angus disproves the first statement, so person A decides that Uncle Angus isn't really a Scottsman and he doesn't count. I say "All X are Y" but then I go on to *define* X as something that's Y, discarding the generally-accepted definition of XIt's a fallacy in making arguments. For example, you say that "no Scotsman believes in free market economics." When someone shows that that statement is false, e.g. by reference to Scottish economist Adam Smith, you change your statement to "no *true* Scotsman believes in free market economics." The problem is that in this scenario you can define "*true* Scotsman" to mean anything you want and prove yourself right. Your argument becomes circular.Relevant: A list of each type of logical fallacy. I believe it's one of the most important things you can memorize._URL_1_

Why doesn't the ocean's water leak out the bottom and into the earth's crust/mantle? The ocean bottom can't be completely free of fissures, can it?
|
* the water doesn't have anywhere to go. There aren't gaping holes for stuff to fall into. Any holes there are has stuff coming out , not stuff going in.* any water that does actually make it to a hole gets turned to steam pretty quickly , and starts going right back up.* rock is more dense than water. That doesn't just mean that rocks sink in water, that means that water _floats_ on rocks. The natural place that water wants to be in relation to a rock is above it, in the same way a beach ball wants to be above water.

Why are my USA made Craftsman tools better than my neighbors China made Craftsman tools?
|
Because of higher quality standards and price. But if you are willing to pay same price for the Chinese counterparts, they'll be better.But the first thing we think about Chinese stuff is that it got to be less expensive and that is where the problem stands.we go so cheap that the thing aren't really worth buying.

Why can diesel engines not rev as highly as petrol engines?
|
In a petrol engine, the fuel is designed to ignite smoothly and burn in a controlled manner. This causes even, smooth heating in the combustion chamber, and produces a smooth force on the piston. In a diesel engine, the fuel ignites spontaneously and explodes as soon as it is injected. This explosion causes a shock wave in the combustion chamber which slams into the piston. The reason diesel engines have that characteristic rattling sound, is this. Each "tick" sound, is the sound of shockwave bouncing off the combustion chamber. Because diesel engines have to withstand these shockwaves, the pistons have to be heavier, so that they don't get smashed. The problem is that the piston has to move up and down the cylinder every time the engine turns. This means that the entire weight of the piston has to be accelerated and decelerated and reversed direction. The faster the engine revs the faster the acceleration. The heavier the piston, the greater the force needed to do this. This force puts more stress on the bearings and the crankshaft. So, to prevent the crankshaft, bearings and connecting rods getting bent by the moving heavy pistons up and down , the engine has to have a lower maximum speedThe faster the revs on the engine the less time each piston has for a full travel of its stroke. Diesel fuel combusts slower than petrol and therefore cannot complete strokes much faster.Diesel engines tend to have longer strokes, i.e., a stroke length that's greater than the bore diameter. Engines with long strokes don't rev as easily. _URL_0_

How is it that rich kids in can get into the best and presumably most exclusive (e.g. Ivy League) colleges, despite having average or poor grades in high school?
|
Give an example of a rich kid getting into an Ivy League with poor High School grades I think you will be hard pressed to find one. Sounds like you are trying to say that rich people don't have to have good grades to get into college, which is a not true generalization. That being said, many private schools take a few Legacy students each year. These might be the people you are talking about. Where they are accepted to keep big family donations coming. I don't think it's as big of a fraction as you think though. Those kids still don't get poor grades in most case. They may be average though . Ivy Leagues like any other school want the smartest kids. Taking dumb rich kids doesn't help them advertise that they are the best school in the world.

how do two brown haired people create a blonde baby?
|
Could be that you carry the gene, as does the father. Genes can be determined using Punnett squares, specific gene combinations are given letters, either capital or lowercase. Capital letters denote a dominant trait that will mask a recessive trait, marked with a lowercase letter. In this example I’ll say that hair colours brown and blonde are given the letter B. BB = brown hairBb = brown hair but carries the blonde genebb = blonde hair It’s likely that you and your husband both have Bb hair genes: Bb x Bb This is worked out in a grid format x B b B BB Bb b Bb bb The letters of the parents genes are ‘crossed’ over each other, capital letters always go first because they are the dominant gene. So this means you’d produce:25 % BB 50 % Bb 25 % bb = 75 % chance of brown haired kid, 25 % chance of blonde. The probability resets with each child, so it’s possible for you to have more blonde haired kids than brown if the blonde gene happens to strike. I’m sure other people can explain it better, I’m only using my year 12 biology knowledge but I tried, hope it helps!In addition to the previous replies, some people are born with very blond hair that darkens over time. They have genes for darker hair but they have not switched on yet.The genetics of hair color haven't fully been teased out yet, but it seems that the genes for blonde hair are recessive compared to the genes for brown hair. So if both genes are present, the person will have brown hair. Only when - by chance - a child only gets the blonde genes from its parents will the hair be blonde. What this could mean is that both you and your husband have recessive blonde genes that aren't apparent because you also have the dominant brown genes but your child, by pure randomness, only got those blonde hair genes.

How come you can put your finger in a bubble if your finger is wet, but not if it is dry?
|
Water is made up of many tiny molecules.These molecules are too small to be seen with our unaided eyes. One drop of water is made up of thousands of water molecules. These molecules are attracted to each other and they stick together creating a force called surface tension. Surface tension is one of water’s most important and salient properties. It is the reason why water collects in drops instead of falling apart. Surface tension also causes the water to have a dome shape when you fill a glass up to the rim. Soap weakens the surface tension of water. It also forms a very thin skin that is more flexible than water’s surface. When air is blown into the soap solution, air gets trapped under the surface of the more flexible skin, stretching it into a sphere shape and making a bubble. A bubble pops when the water trapped between layers of soap drys up . Therefore, when your finger is wet, the bubble does not burst.

How do you just lose a Boeing 777?
|
Satellites and radar are notoriously poor at seeing under the surface of the ocean. Which is where that jet undoubtably is, unless a James Bond villain has it in his secret volcano lair. Plus there's a pretty large area to cover. There are special radars that can be deployed by ship , but they still have to pass near the correct location to have a chance to spot anything.

In chess, why do players resign when it seems like there is alot more of the game to play? Why not play to the end in case the opponent makes a mistake?
|
Either you're in a situation where it would be an insult to imagine your opponent making the kind of mistake that would result in a draw, or you're in a situation where you can salvage a little bit of grace by recognizing an inescapable trap before it's completely obvious. It's saying, *I wasn't good enough to avoid it, but at least I'm good enough to recognize it when it happens.* You don't resign like that unless you're sure: it's extra embarrassing to resign, and then have it pointed out that you could have escaped by doing this, this, and this. And, in a whole other category, sometimes you just want to stop playing chess, and don't care about winning or losing any more.They resign because the chances of the really good players "making a mistake" is quite low under those circumstances. They both pretty much see the way to the end and don't need to play it out.two reasons: No path to victory remains, or frustration. I see these all the time in pokemon battles. I use a Ditto with Imposter, which lets it transform immediately into a copy of their pokemon when sent out, rather than making me lose a turn. Since I have a choice scarf, I almost always go first. People often resign soon, as i start sweeping their team with their own pokemon. However, because of the Choice Scarf, my ditto will be locked into a single move. And sometimes, there's nothing I can do. I might get locked into Earthquake, and they have a Flying pokemon. After five turns I'd start damaging myself and the outcome is inevitable. Almost. I have won using my Ditto like this. When the Struggle that I used that ends up taking me out, also takes them out. But that rarely ever happens. So aside from that 1/1,000 scenario, I just give up because I can't win. Its like that in Chess, but with less Dragons shooting meteors at each other.

Why do voters have to register their party affiliation, and what does that mean?
|
IIRC: you only have to register your party affiliation if you want to vote in the primary. If you want to vote in the actual presidential election, you are not required to do this. The primary itself wants only their own people to vote in the primary, so people from across the political aisle won't be involved in putting forth who they are front-running candidate is going to be. But ultimately, the primary doesn't have any sort of political office to run for, it's just sort of an election to see who should be in an election.

If there is a past image of our world being projected through space, could we use technology to intercept those images and see what our world looked like millions of years ago?
|
The only way we could see an image of the past earth would be if it were reflected back to us. If there was some gigantic mirror out in space then we could look at it to see what the Earth looked like in the distant past. But, for many reasons, this isn't practical. But, we can't directly catch up with the image of our world because it would be travelling at the speed of light. In order to catch up with it we would have to travel faster than the speed of light which is impossible.

Why do far Eastern people generally have thin eyes? As in the genetic reason if there is one.

I have read it is thoughts be an adaptation to extreme cold. Eskimo use snow goggles that have no lenses but have thin slits to prevent snow blindness similar to squinting all the time. Also, Asians have the epicanthic fold, which is like an extra eyelid over to top one, possibly adding some insulation from cold or making it easier to sleep under a minight sun.Their eyes aren't thinner. They just have an extra layer of skin under their eyes that make them looking thinner.

Can someone explain the Story of Classic Doctor Who and the history of the Great Time War?
|
The time war is not explained during the classic series. It was something that happened between the classic series and the new one, and has only been elaborated on in brief mentions and a flashback or two. There's been a lot of speculation that this will be the subject of this year's Christmas special, which is rumoured to be 120 minutes in length.It happened between the previous series and the new one so, for the most part, everything that there is to know about it is included in the 2005-present show.

Why do people upload torrents?
|
On private trackers it's important to seed as much as, or more than, you download, both for the community contribution and to simply be allowed to continue using that tracker. On public trackers it's probably either a sense of community, or people just don't realize that they're also seeding when they finish a download.

Why do electronics get ruined by water?
|
Non purified water is a wonderful conductor of electricity. electricity will follow the path of least resistance. In devices electricity is only supposed to go where it is designed to go. the water lets the electricity go places it shouldnt and the magic smoke escapesThe water basically creates circuits around the circuits. This leads to excess current in places that cannot handle the current. This is known as a short circuit. When things receive more current than they can handle, they tend to catch fire or explode.

Why can't recovering drug addicts have alcohol?
|
Some recovering drug addicts do drink alcohol without abusing it. Though, the statistics seem to say that most recovering addicts cannot drink alcohol without also abusing it. Most recovery programs teach that if you are an addict to once substance, you have the increased likelihood to abuse other addictive substances. As such, their advice is to avoid those substances in general. The deal with nicotine is this while it is definitely addictive, its effects are not socially destructive, as the effects of alcohol, or cocaine, or heroin . Nicotine definitely is hazardous to one's health , but its effects are mostly personal and take a relatively long time to show up. It is unlikely that no matter how many tobacco cigarettes one smokes, you are not going to be so intoxicated that while driving you will cause an accident resulting in the injury or deaths of other people.

How/Why does the NBA's poison pill contract, like the one offered by Houston to Asik and by Toronto to Fields, work?
|
Some teams cannot go over the cap or wish not to hurt themselves in the long run with a contract that is "poisoned". Using Asik's example, his contract I believe is made to go 5m/5m/15m in \'13, \'14, and \'15. But when an opposing team offers this kind of contract to a restricted free agent, it is counted evenly across all three years like 8.3m/8.3m/8.3m, which gives it some cap flexibility across all three years. If the Bulls choose to match that offer sheet , it will count against their team the same way Asik's contract is structure. So during 2013 and 2014 years, it will have a 5 million dollar penalty against their cap, but in 2015, Asik will be counted as 15 million in their salary budget and teams don't like to commit so much money to a player like him, because it severely hampers your ability to sign free agents. Therefore, Chicago is less inclined to match Asik and let him go, even though he might be considered a valuable asset to them. Toronto is doing the same thing to the Knicks, since there are rumors of Nash going to the Knicks, so Toronto is sort of bullying the Knicks in order to choose between Fields or Nash.

why there is so much "US Only" content on the internet
|
You mean TV shows, like how we can't get on the Daily Show YouTube channel in the UK? It's largely because once you 've made your programme in your native country, you can then sell the broadcast rights to channels in other countries. When you 've got a show to sell, the price will be much higher if you can go to the negotiating table and say: "This is a very popular show, and nobody in your country will have seen these episodes. They are exclusive to you. People will tune in to your channel just to see it first." than if you say: "Our show is really good but your audience has already seen the best bits on YouTube."Mostly because of copyright and broadcasting rights. Say you are in the UK and want to watch an HBO show. HBO's agreement with, say BBC, might require that they not allow UK viewers to stream their show because BBC wants to get more paying viewers. HBO is then forced to forward these terms to Hulu, Netflix, YouTube, etc as part of those sites being able to show that HBO show. In rare cases , there may be an actual embargo in place that legally limits what can be "exported". Downloads are actually considered a type of export in those cases.I'll trade you hulu for internet poker, deal?

Where does the energy for the rotation of the earth come from?
|
Gravity and conservation of angular momentum. The planets and the solar system all started out as a big ball of gas/dust. As this ball collapsed inwards due to gravity, it gained rotation. The more it collapses in, the more the rotation increases to conserve angular momentum. The energy for this increased rotation comes from gravitational potential. The more spread out the ball is, the more gravitational potential energy it has. So as it collapses, the gravitational potential gets turned into kinetic energy which is seen as an increase in the rotation rateThe Earth was rotating before, so it continues to rotate. Nothing is stopping it, so it continues, as is one of the 3 laws of motion.
|
How the hell does gravity pull things through a vacuum?
|
It doesn't pull, exactly. It may be easier to think of space as tablecloth pulled taut; if you put something on it, it makes a dent. The "dent" is the deformation of space by the mass of the object. This deformation literally bends space and results in the object still going in a straight line that has been deformed by gravity. tl;dr: you are a human tractor beamIt's "attracted" to the Earth because of it's much larger size. It's like opposite polarity magnets, they would still be attracted to each other even in a vacuum environment, right?

Why do my joints crack and click during random movements?

Your joints or ligaments are filled with fluid and when you move it can create a partial vacuum. It expands and then rapidly collapses, creating a popping sound. Reduce the amount? Don't crack your knuckles. But there's no evidence that this can lead to arthritis or any other harm.

Why are 'geniuses' always good at math?
|
It honestly depends how you view geniuses. If like a lot of people you think geniuses dont simply have to be very smart and have a high IQ. For example if you think people can be lyrical geniuses or comedic geniuses etc. Than they likely wont be good at math. If you are only talking about smart people they are likely good at math because its just numbers and formulaes etc. You can learn the basics from a young age and perfect it while your brain is still very fresh and open this is why high IQ is usually born instead of made. As well as this its a fundamental part of life, you will always need math in life but other school stuff is less important

What would happen if the United States stopped paying toward the national debt?
|
The US defaults on its debt. Several nations with abysmal financial systems have done this in recent years. If the US government defaulted and needed to borrow money in the future it would have to pay a significantly higher interest rate, since creditors would no longer see the debt as highly secure. The US pays a really low interest rate on a lot of its debt since it has a stellar record. Nations like Greece and Argentina have to pay staggering double digit interest rates due to their past financial woes.

Why is Russia attacking ISIS a bad thing? Why are not more countries fighting it?
|
One of the biggest issues is its approach. IS is one of three issues in Syria currently. On one side you have Assad's regime, which Russia supports. On the other, you have the rebels fighting to overthrow Assad's regime, which America supports. This is the main issue between Russia and America. America sees the Assad regime as oppressive and wrong, and wish it to be overthrown. They're training rebels and supplying weapons for this cause. Russia supports Assad, and is against the resistance to him. America and Russia are aligned in wanting the IS destroyed, but not in terms of how. Russia doesn't mind if the rebels are killed alongside IS fighters, and are less worried with how they achieve their goals. They see Assad as the lesser of two evils, and don't wish to destabilize the area by removing him. On that note, a destabilized Syria would likely become a stronghold for IS. America sees Assad as oppressive, and wishes to see him removed, much like Saddam Hussein. This is obviously a conflict of interest between the two, and the media is selling it as Russia blatantly going against the US.Russia has captured the moral high ground in framing their activities as "attacking ISIS," but its real interests are stabilizing Syria with Assad remaining in power. Likewise, the US and its allies in the region are more interested in toppling removing Assad than eliminating ISIS. There are a number of militant groups that are being funded and used in this proxy war. ISIS is simply one that got out of hand.A major concern is that Russia is not specifically targeting ISIS, but any target Bashar Al-Assad gives them. This would include ISIS, but also independent organizations fighting him in civil war, even parties which the United States works with. As far as 'why not more countries' there are quite a few countries involved in this conflict.

Why is the standard for songs 3.5-4 minutes?
|
Because of vinyl. When records were the standard for recorded music, the standard size for a record of a single was just large enough for, at most, four minutes of audio. To make the records much larger would have made them more costly and thus the music industry would not have been able to sell as many due to increased costs to the purchaser. A lot of space was needed to mark the complex sounds of music on records, after all. So in the interests of music being affordable and thus ensure that records became widespread, they were kept to a maximum size that didn't allow for much more than 4 minutes of sound. At this point though, when recorded music can be downloaded easily and with relatively small file sizes. It's more tradition than anything now, though, since for so many decades 3.5-4 minutes have been the norm, nobody wants to change what works and what sells.

Why is self-plagiarism a concept (outside of academia)?
|
The author might not own their own work. If King had written those words in an essay and sold or given publication rights to a magazine, it would be self-plagiarization. Also, the audience generally has the right to know whether they are hearing an original work. A lot depends on what a reasonable expectation of originality would be. No one goes to an Elton John concert to hear his new stuff, but if you hired someone to be a keynote speaker, you'd expect they will write a new speech tailored to your event. Self-plagiarism in this sense is a more hazy concept and is usually in the real of ethics rather than law.

Why does a lower value currency have an advantage in international trade?
|
When you export goods, you usually make the people buying your goods pay you in your domestic currency. If I'm an American company, I want U.S. dollars for my wares; I don't want you to pay me in a foreign currency. This means that if the value of the U.S. dollar goes up, it becomes more expensive for people abroad to buy my goods--the price might've staid the same in U.S. dollars, but that now converts to more Euros or Yen. Conversely, if the exchange rate goes down, you can cheaply buy my goods, even though I'm getting the same amount of dollars as before--business will be booming. The benefit happens when the currency exchange rate goes down, but there is not inflation in domestic prices to match. If prices in America stay the same, but the exchange rate makes the dollar cheaper, then all of the people abroad are getting a discount, and I still get paid the same amount of money! For this reason, countries that want to have lots of exports try to artificially drive down the international value of the currency, while also attempting to combat inflation.

How animals seems to have the sense from birth that fire is bad but humans often have to get burned before realising?
|
Humans have made a sort of evolutionary tradeoff: we are born with our brains much less-thoroughly developed compared to their adult state than other animals, with the result that we are more adaptable, but must learn all sorts of things that most animals are born knowing, such as how to walkRegrettably, my cat tried to "smell" a burning candle once. He had no idea what fire is. Smoke on the other hand, makes my cats want to head for low ground.I just want to say that not all animals realize fire is bad. When I go outside to have a fire my chickens are right there I have to chase them away. In the winter we have a huge fire of all the fallen trees - and stuff.. and my livestock critters are not scared. They don't go into it or any thing like that but they don't exactly stay away either.

Quantum Computing and Quantum Mechanics
|
"Quantum" just refers to the idea that you can break up any quantity into small bits, but no smaller. So a "quantum" of light is called a photon - you can't have half a photon. Quantum mechanics is just the study of physics when you're dealing with individual quantities like this. As for quantum computing, it deals with a particular idea of QM called "quantum superposition" - the idea that an atom can actually be in any number of states simultaneously, and that it doesn't "choose" what state to be in until you look at it. This is useful in quantum computing because currently, classical bits can only hold either a "0" or a "1", which is only two states. If you want to represent 4 states, you 'd need two bits. Eight states would require the use of 3 bits and so on, as powers of two. With quantum bits or "qubits", you're dealing with a quantized state to represent your information anything from the polarization of a photon to the spin of an electron. However with QM, the system is allowed to be in a "superposition" of any possible states. So instead of a 1 or a 0, it could be a little bit of 1 and a little bit of 0. This means you're able to hold a lot more information than is generally possible with classical bits. The tricky parts of Quantum computing are the actually reading/writing of data, as well as being able to encode the data for storage - many of these quantized states don't have long "coherence times" which basically means they decay very quickly. Often you're able to keep them long enough to compute with them, but not to actually store them for reference later on.

EL5 What exactly is meditation, how does it work, and what are the benefits of it?
|
Meditation, as a broad topic, simply refers to any kind of focused thought. This can be anything from thinking deeply and critically about something you have learned or experienced to religious reflection to striving for complete absence of conscious thought. As for the benefits of such practices, in many ways you can think of it the same way you think of physical exercise and it also shares many of the same benefits. When you make a regular habit of focusing your attention you will, over time, become better at focusing on one train of thought for longer and longer periods. This has many side benefits such as reducing anxiety and stress since you are not focusing on the patterns of thought that cause your body to react in such negative ways. You also learn to calmly approach problems whether they are academic, practical or emotional because you have trained yourself to take a methodical and determined approach to accomplishing such tasks. To try out a simple exercise, the next time you read something interesting or learn about a controversial topic take some time to put down what you're doing, turn off any distractions such as the TV or computer and sit quietly and think about what you have just experienced. What was your emotional reaction? What other positions are there on that topic? Can you think of a time when you have encountered something similar before? How does this information impact your life? How does it impact others? Where did this information come from? etc. Do this for at least ten minutes before you even google the topic or seek any other information or discussion of it . Keeping a written record of your thoughts is also extremely helpful.

Why do we say "cold doesnt exist - its the absence of heat"? Can I say it backwards? "Heat is the absence of cold"
|
Heat is a form of energy. Cold is nothing, a lack of energy. You can supply energy to something, but you can't supply a lack of energy--you can only draw energy away to another place. The concepts aren't arbitrary; energy is something measurable that follows physical rules, just like matter.It's linked to movement. Heat is essentially the level of movement of the atoms and molecules in something. The more they are agitated and move around, the greater their heat level. So let's try talking about them with the word 'movement\'. * "Cold is the absence of movement". Sounds okay. * "Heat is the presence of movement". Yeah, that's ok too. But, change it around to stillness. * "Cold is the presence of stillness." Meh. Bleh. Could be worse. * "Heat is the absence of stillness". No. Yeck. Really doesn't sound right. So we go with the first reference because heat - essentially atomic-level movement - sounds better when said in that way, possibly because it's associated with an action rather than the lack of one.Heat is a form of energy. If something is warm, it has more energy in it. If it is cold, it has less energy. It doesn't really make sense to say heat is the absence of cold because you are effectively saying that having energy is the lack of the lack of heat. Cold isn't actually something you can measure, we use the units for heat .

Why do we get "sand" in the corners of our eyes when we sleep? And why do we not get it during the day when we're awake?
|
The "sand" is actually dried tears. That is, tears are similar to salt water -- liquid with salts in them. Overnight, when the tears at the edges of your eyes dry, the salt is left behind as "sand"To expand on what above said, the reason it doesn't happen we are awake is because we blink which spreads the "tears" around on our eyes, when we sleep they tend to build up in the corners of our eyes. But yes they're dried up salt water If we didn't blink for a whole day would you get "sand" all in or random parts of your eyes?

Does my breastmilk have healthier properties if I eat healthier food?
|
Regarding healthy and unhealthy fats:generally speaking: the membranes of your cells always feflect the stuff you eat. Of course the body has its own fattyacid metabolism and can contribute here. but regarding the fats the general rule applies: you are what you eat.On the other hand: the milk you produce contains still certain healthy components eitherway. like omega3 fats that are important for the brain of the baby. Thats a propriety of breastmilk that should not be influenced by diet.

What is a superdelegate?
|
A superdelegate is a high-ranking official of either the Democratic or the Republican party who is automatically seated to their respective conventions without having to be elected to participate. Usually, these are current or former holders of high-office or high-ranking party officials. In the context of the presidential primary election, these individuals are automatically seated and get a vote in determining which candidate the party will formally nominate for the general election under that party's banner. Unlike "regular" pledged delegates that are chosen in primary elections and are largely bound to support the candidate they represent, superdelegates are free to vote in their conscience, or for whom they personally believe would be in the best interest of the party as a whole. Because of this, there are many who believe that this gives undue influence to the establishment, and limits the will of the people as a whole to determine which candidate should be nominated - it is possible for one candidate to get a majority of pledged delegates from primary elections, yet lose the nomination if a sufficient number of superdelegates back a different candidate.

If you jumped in a giant hole in the earth that was deep enough to reach the other side of the planet, what would happen to you?
|
Let's say the earth is cold and there is no wind resistance that can heat you up. Also the earth is not spinning, this would result in you ricocheting of the walls. You would accellerate all the way to the center of the earth, there you will be traveling at your fastest speed. When you are past the center you will slow down until you would peek up from the hole on the other side. Then you would do the same thing again but the other way. [This video will explain.]

what is "Tilt table test"
|
When people stand up, their blood pressure often goes down . When this happens, in most people your body senses the drop in pressure and compensates by increasing your heart rate and constricting your blood vessels using whats called your autonomic nervous system. If people have trouble with this system, or can't compensate, they can often have a big drop in blood pressure when they stand up, which can lead to fainting . The tilt table simulates standing up by gradually tilting upwards from flat to straight. In this way the patient can be safely observed without the risk of them fainting, and under controlled conditions. Does that answer your question?", 'You get put on a table and tilted so that your head is down and legs are up, and vice versa. Its used most commonly to diagnose cardiovascular problems

When a woman gets pregnant, the present "physiological status" of the parents affect the baby? [read the text]
|
If the damage doesn't affect either parent's DNA or the baby in the womb damage to the parents won't affect the baby. For example if your left leg is blown off in an explosion your genes still have the code to grow a left leg - it's just not there anymore. When you have a child, they will grow a left leg like normal even though you don't have one because the genes you passed down to them still have those instructions. There are some experiences parents and even grandparents have that can change how their genes are expressed, but don't actually change their DNA code. This change happens through epigenetics, which is basically how your body chooses to turn a gene on or off. For example, if your grandparents lived through a famine their experience with hunger may have turned some genes on or off through epigenetics. This change was passed down to your parents, and ultimately you.

Why do bubbles appear at the heated area of a boiling kettle?
|
All matter can have three states: solid, liquid, and gas. Normally we see water as a liquid. When water is heated above 100 degrees C , it becomes a gas. This requires a lot of energy to turn the liquid into a gas . Energy comes in many different forms. The one that we care about is thermal energy, which in layman's terms is 'heat'. The bubbles you see are actually little pockets of steam rising from the interface between the metal and the water. The heated area has the most bubbles because that's where the energy is being added.

What is the evolutionary benefit or reason for the Tyrannosaurus' small arms? How did it succeed as a predator with this shortcoming?
|
It's very unusual for a body part to evolve away completely. All land vertebrates are tetrapods - this means they have four limbs and a head. The only vertebrate I'm aware of to have completely broken that is the snake - other than that, everything has four limbs . So in all likelihood, the evolutionary benefit for the small arms was merely that the tyrannosaurus didn't have to waste so much energy and food growing them in the first place. It's the equivalent of cave mice being blind but still having eye sockets - it's a vestigial remnant of a more-or-less unneeded body part.

Why Operating Systems are architecture specific (ex. X86 , ARM) but applications are not.
|
Applications are architecture specific. It's just that you mostly use AMD64 CPUs with fitting OS and then run x86 applications. Like the name suggests, x86_64 is just an extension of x86 and x86_64 is backwards compatible. You just can't mix both in one application. That's why your Windows has a System32 directory and SysWOW64 directory. The 32bit stuff is in the latter, the 64bit stuff in the former. An ARM application simply wouldn't run on the x86 architecture. At least not a native applications which is why Java or .Net applications run on everything that has Java or .Net. The Application itself is not compiled for Windows or AMD64 but for the Java Virtual Machine which is a virtual machine that then runs your application with code for your platform .Applications are, unless they are compiled at runtime in which case they are universal because they are turned into machine code for that processor as they are run. This is why the SysWOW64 directory exists in Windows.

How did we discover math?
|
Math is so pure and simple, facts are facts and concrete rules define all the relationships. Only Barbie thinks "Math is Hard", but her head is full of hair. Counting started before written history, systematic numbers were defined by the Sumerians, number place was invented by the Babylonians. More kinds of math were invented when the math we had couldn't do the problems we were studying. One of the last huge steps was Calculus. Isaac Newton and Gottfried Leibniz independently invented calculus in the mid-17th century. Even today we're looking for new ways to explain and teach math. A lot of discussion recently has examined the Common Core Math approach in comparison to the previous technique .

Why is tap dancing so ubiquitous in old musicals?
|
Movies were still close to their live theater roots at that time, a genre where microphones could not be used. To entertain a large theater, you spoke loudly, sang loudly, and when possible, danced loudly.They were made by people from an era where dancing was public performance. Half the actors in old musicals are Broadway stars. When you do live entertainment, you'd better know how to do pretty much everything, because there are no Cuts retakes splices and post-production.

when you hyperventilate, why do your hands and face (and other parts) go numb?
|
Well, I'm no doctor, and I didn't look it up real fast so this is just what I think: Hyperventilating makes you breathe faster, making oxygen travel quicker out, right? So maybe the 'numbness' is less oxygen in your body? Just how I see it, not actually what it may be.

Why is deafness and blindness fairly common, yet we never hear of people with impaired smelling or taste?
|
Impaired taste and smell is also fairly common. It however does not prevent you from doing most jobs, and does not hinder your social interactions so it being known publicly is not very important.Because they get along in society just fine. Your co-worker or neighbour or cousin might have it, but he doesn't bring it up because he doesn't have to. If he were blind, however, you would immediately notice.

Why is green poo bad?
|
Like a lot of medical symptoms, it can be concerning, but isn't necessarily bad. In brief, though, sometimes green colored stool is just the result of eating a lot of dyed food . However, the green color can also indicate the presence of bile in the stool. Bile is a fluid made by your liver and used by your small intestine; it helps you digest fats in food. It's supposed to have been reabsorbed by the time the stool makes it through your large intestine and out of your body. If there's still a lot of bile in your stool, it can indicate that something is irritating your gut, and making stool pass through much quicker than normal. If it's a one-off thing, you're probably fine . If you have more than one, it's probably worth talking to a doctor about.

How come so many people believe that "the _URL_0_" is real?
|
My guess is that its the same way telemarketers work, they ring heaps of people and maybe only 1% of people will buy, but that 1% is enough to become rich. Since this website is a $100 subscription, all you need is 100 gullible people to scam and you're already $10,000 richer.I don't know if its a scam or not but XPRS has a promotion offering free premium license for all the waiting founders. Its a working system, way smarter than the so called "AI" the thegrid are promising. _URL_0_', "I don't understand how this is supposed to make you a millionaire. The website talks about self-generating layouts; from my point of view, it seems an useful tool for webmasters. Am I missing something?

Gene therapy and how it works in this article about my disease
|
So your body's "blueprint" is kept in a giant molecule called DNA, and a small section of that DNA is flawed causing your disease. It's like a lengthy instruction manual with a page ripped out or smeared. So that part of your instruction book is now telling your body through a series of indirect steps to produce a certain protein that is also defective, and that defective structural element is what's causing your condition. So the first problem is providing correct instructions via inserting a printout of the corrected pages. They know what the pages are, but how to get them to the sites where they can be used instead of the flawed ones in your DNA? This is the second part of the problem, and they solve it with tiny virii. The process of telling your body to create the protein is buried behind a massive firewall in your body called the blood/brain barrier, and sending in better instructions to fix the issue requires a VERY tiny messenger that can pass through this barrier. Normal virii reproduce by passing through cell membranes and inserting their own instructions to tell the cell to "make more virii, not more cells". What these sciency guys have done is to take a virus that's tiny enough to pass through the blood-brain barrier, and then fill it instead with replacement instructions THEY WROTE into the cells involved in the process that creates the bad protein. "Here's the bad bit of instructions, snip that out and replace it with this good bit of instructions." Massively. Cool. Stuff. So your body uses these replacement instructions , generates the good proteins now, and the issue is fixed.

Does weed being in your system have any mental effect on you when sober?
|
THC has a half-life of 2 to 56 hr. It takes 5 half-lives to clear the drug from your system. So if you are a "slow metabolizer" , you may be "high" for a lot longer than you think .There are two effects. First, marijuana does cause mild withdrawal symptoms if you're a regular smoker. The second is that there is still some THC in your body. THC is absorbed by fat, and then released into your body when that fat is burned. Since your body burns some fat constantly, you have some THC that is constantly being rereleased into your system. This is also why marijuana is detectable in drug tests for so much longer than other drugs.

don't drivers' weights mess with the overall stability / weight distribution of those expensive, high performance cars? how is this solved?
|
The Mazda Mx5, as far as I'm aware is designed to be "perfectly balanced" on half tank of fuel, and a driver of a specific mass . No passengers either. I have no idea how this is achieved, but the design does take into account that the driver sits to one side.They do. And people who care enough go to the trouble of dealing with it. To most of us it doesn't matter, but think of an F1 car. The driver sits dead center. No lean. On the other hand, those cars go at about 3 times the speed most of us will ever drive at, and they care about fractions of a second on a lap time while we lose a few minutes if we get bad luck with red lights. The same kind of performance isn't really something we need.

What is Glencore and why is it a threat to the control of mankind's resources?
|
It is a mining company. It controls 60% of the World market for zinc, 50% of copper, 9% of grain, and 3% of the oil market. This would be all well and good if they were a nice friendly little outfit committed to sustainable development. However their history "reads like a spy novel", and they have been involved in a host of incredibly dodgy business dealings, corruption, environmental destruction and general misery. They're a nasty huge multinational and behave like the evil companies conspiracy theorists in movies tell you exist, but you didn't believe actually existed for real.

The circumstances surrounding Army Sgt. Bowe Bergdahl?
|
The people we released were dangerous, the conditions of his desertion are cloudy. This biggest question is what takes precedence: No man left behind or we don't negotiate with terrorists? Both are mantras we live by. It is also important to note that he was on the brink of death and his health was very poor. We also don't know whether or not he was implicated in some top secret intel gathering mission and his desertion was a ploy. Since we will be out of Afghanistan soon we want to make sure we have all are POW before we leave, he was the last to my knowledge still in captivity. What we also don't know, and is plausible, is whether or not these Taliban leaders are working for us, and if they have gps implants. We could be sending them back to lead us right into their base, then a drone comes along. There are so many possibilities here, I have to have faith in our military and I believe they know what they are doing, even if we never find out the true motives. This has become an issue, but I think there is more to this than we know right now.

Why are bidets and other water integrated toilet seats common in Europe and other countries but almost non-existent in the US?

I come from a country in Europe where bidets are normal. The main use is to ~~earth~~ wash your feet and to place the dirty clothes while you shower. Babies use them as washbasin.Adam ruins everything did a piece on it in his flushable wipes video Pretty much they became synonymous with hookers and brothels. because of this people didn't want them in their homes. Imagine inviting a guest over and they think you're a hooker because of a piece or porcelain in your bathroom.

the physiology of that "butterflies in your stomach" feeling.
|
From what I've heard before, that feeling comes from our Fight or Flight instinct. Your body senses that you're nervous for something coming up, and as a natural response from the fear, your body begins preparing itself for the potential of fighting/flight. It sends more blood to the more important areas of your body so that if you have to fight/flee, you can in a better way. The butterfly feeling is what happens when blood is rushed away from your stomach area, simply put.I'm no physiologist, but I am a medical student, so I could be wrong but: The induction of stress will lead to a shunting of blood away from your gastrointestinal tract and other non-essential organs during fight-or-flight to essential organs like the skeletal muscles et al, resulting in decreased GI peristalsis, and decreased secretions in the stomach and intestines. The "butterflies" might be fluids remaining in the intestines along with the stuff being digested, giving off a slight noxious feeling. The fluids and digestive remnants are probably moving from the momentum of the peristaltic movements and are settling while the rest of your body reacts to the attack. **Now, like your five?** Hey, there, little buddy! Is your stomach feeling like butterflies are flying around? Don't worry, little guy! That's just the food you ate. Your brain told your stomach "don't be afraid, i'll take care of the bad guy you just sit right here!" And told the stomach to sit down until he gets back. But the food in the stomach was still sliding down, so all those butterflies in your stomach is really just the food still moving while your stomach is sitting still. But don't worry! Your stomach will start moving again and your brain won't be scared or excited for too much longer. And pretty soon, you'll be pooping in no time!

How the hell does a 3D printer work?
|
It works like a plotter, only it is oriented with the "pen" facing downward instead of parallel to the ground like on a traditional plotter. The robotics are controlled by computer software, and typical 3d printers use a plasticy resin. The resin is melted and pushed thru the "pen" to go down onto the base, dries and turns hard. The pen is on an arm that will move according to the computer's directions, leaving a trail of the resin behind it. Once one layer is printed, it will start on the next layer by "printing" directly on top of the prior layer. A 3d printed object is printed layer by layer in this fashion until it is finished. There are all sorts of cool things you can make with these things, and you can even print most of the parts that you need to build one of your own!', "> It's like frosting a cake. Except instead of frosting it's melted plastic. There's a robotic positioning system, RPS, that is able to be very precise with where it's putting the frosting, I mean plastic. The plastic hardens quickly enough that it can be layered on top of itself. So, instead of just drawing on a cake, you can layer it and make actual things. This is why we use plastic instead of frosting. Frosting is too soft. _URL_0_

why do modern rockets blast off with zero initial velocity (standing straight up)?
|
The biggest difficulty in getting enough speed to get to orbital velocity is how the earth's atmosphere slows you down. It is most effective to blast straight up until the atnosphere becomes thinner and the drag caused by the air becomes very low, then level out and accelerate sideways towards an orbital speed. Also turning while in atmosphere is very difficult to do, again due to drag wanted to slow down any surfaces that aren't aerodynamic to the direction of travel.Every second spent moving through the atmosphere or crawling on the ground/tracks/ramp adds friction and steals a little bit from the energy of the craft. Going straight up completely eliminates ground friction and gets you out of the atmosphere as quickly as possible, making all motion after that easier. Additionally, rockets are basically a big engine with stuff on top. To work on tracks or roll along a ramp or even clamp onto a plane, it all requires additional parts- wheels or skates or clamps- and every bit of weight countsthere are various concepts of ramps and slings and sleds that have been theorized, but none are currently viable. It would be a huge departure from what we know, adding a new phase to the launch rather than just *more* of the same. the track would need to be huge, complexity, investment, ect. It will probably get superceded by a space elevator, or so we hope.

how does thought work without language? When I think, I formulate ideas in words. How did this work either prior to language or for people who have no concept of language?
|
Most thought does not use language. When you see a scary spider you don't feel the scariness because of the word "spider." When you are hungry and know you want to eat, that didn't come from language. When you see a beautiful nature scene, it's not beautiful to you because of language. When you decide to put on your socks before your shoes, you didn't need language to take that actionLanguage is not just spoken. Thought is a nonverbal language and the act of expressing it is called communication. Thus, you can communicate without language. By gestures, or even just a look.

Why does the letter H exist in Spanish if its silent?
|
For historical reasons. Languages change and evolve over time, and the way sounds are pronounced change according to some definite rules. One of those is called Grimm's Law, after the person who first discovered it, Jacob Grimm of Brothers Grimm fame , and one of the consequences of this is that the "h" sound can fall silent. You can see Grimm's Law in effect if you go back five or six thousand years, to a language linguists call Proto-Indo-European, the ancestor of languages spoken all over Europe and parts of Asia today. Start with PIE *nókʷts . In modern German, it's "Nacht" -- the "kʷ" has, thanks to Grimm's Law, changed and become a German "ch", which here is pronounced with that back-of-the-throat raspy sound that English doesn't have. In modern English it's "night" -- the "gh" represents a much gentler version of the German "ch", which is also thanks to Grimm's Law, but then -- also thanks to Grimm's Law -- it changed again and became silent, so now English has a silent "gh" in words like "night". But we still write the "gh" because we have never bothered to have a proper reform of English spelling. Well, that's the same reason Spanish has a letter "h" which isn't pronounced. It *was* pronounced at one time, but thanks to Grimm's Law it has become silent, but it's still written. Of course, it *is* useful as a letter to put after "c" to change the sound it makes , so it's not completely redundant.

how does dust settle on vertical surfaces like glass panes? Shouldn't it just fall off?
|
It may be due to the irregularities in the surface, but it is more likely caused because the dust particle is statically charged, and it attracted to the vertical surface. Glass panes can be charged relatively easilyThings only look flat to us because of our size. Zoom in on your tabletop enough and it would be as filled with valleys and ridges as any mountain range here on earth. Dust is very small and light and will grab these ridges and such as they make contact. I guess it works in a similar fashion as our fingerprints. The ridges on our fingertips give us grip. Same deal with your "flat" surfaces. Other things that would contribute would be moisture and static charge but it is usually a combination of the three that does it.

How do towing companies tow away cars when the car has its parking brake engaged?
|
On most cars the parking break only locks the back tires. The towing company lifts the car by the rear end, because the front tires turn freely. Some models of cars only lock the front tires though, and they'll just reverse the procedure. When those aren't viable options the towing company will place a set of tires, connected by a brace, under the tires of the side of the car which is making contact with the ground. [Here is an example].

So I wanted to understand how do authorities verify when a mountaineer has actually reached the peak of a mountain.
|
They don't and there are no authorities. Historically there were so few people climbing mountains for fun that they all pretty much knew each other and climbing a major mountain usually involved a large team of climbers and an even larger team of support staff that you really couldn't lie about it. TL;DR, Honor system.

Car related terms such as...
|
Liter is a unit of volume, like a gallon. The more liters an engine has the bigger it is, which means it has more power, but uses more gas. Torque is a unit of force. You can think of it as like the strength of car. A high torque vehicle, like a strong person, can carry a lot of weight without straining. Horsepower is just what it's sounds like. 1 horsepower is the power of one horse. Basically it's torque over time, which means it has more to do with speed so sports car has less torque than a truck, but more horsepower because what it can carry it carries faster. Another term is RPMs which is a measure of how fast the engine is spinning your transmission handles how directly the engine is connected to the wheels, so if your engine is working to hard , you want to get it into a higher gear. Acceleration measures how quickly a car can increase it's speed. Top speed measures how quickly a car can move once it get's going as fast as it can go. So a little Italian sports car can accelerate quickly to it's top speed, and then stay there While a big american muscle car might take longer to speed up, eventually it'll get going faster. But honestly dude? This is your first car? there are two numbers I would be watching for MPG and Price. You don't need to be winning any drag races in this thing, you need a car that runs, and keeps running without breaking down too much or costing you a fortune in gas.

why does the American Military measure distance in meters? But the rest of America uses feet and yards?
|
The last thing you want in the middle of a firefight where multiple countries might be involved is to have two different measurement systems being used. Example being Brits come under contact and U.S. is in the area to provide assistance and everyone is giving different measurements to pass information on enemy positions. Especially if requesting indirect fire support The military operates frequently with international partners, and the last thing you want to do when planning a joint military operation is to screw up a calculation somewhere and people wind up at the wrong landing zone or hit the wrong building

What are the differences between ego and self respect?
|
Well, they are both related to how we view ourselves but I would say the difference is self-respect is healthy, and ego isn't. Ego leads to thinking someone is superior to others, prevents one from admitting mistakes, or leads to not taking the experiences and feelings of others into account and only considering one's own feelings and experiences. Self-respect is more about one's relationship with themselves. It leads to treating one's self well, not accepting poor treatment from other people, and having confidence. It's also worth mentioning that ego is a term used in many different contexts in psychology and philosophy and doesn't always mean something bad. In general it's just describing someone's sense of self or individualism. That might be causing you some confusion as well. For example, the Egocentric Predicament is a concept in philosophy that states one can only.ever experience the world from.their own point of view. In that sense, we are all egocentric, but that's not necessarily a failing.
|
Why exactly is it that when siblings (or closely related people) reproduce, there are problems?
|
It's because lots of defective alleles are recessive and rare. So they almost never cause problems because it's very unlikely that both parents have the same defective allele. Even if you have a defective allele and pass it to your child, your mate will provide a functioning allele that can compensate. But now say that your mate is also your sister. There is a 50% chance that she has the same defective allele as you, and now there is a 25% chance that your child will have two defective copies and therefore have the defect. That's the basic principle. When your mate is closely related, there is a much higher chance of the children receiving two copies of any defective recessive allele.

It can even show ST elevation on an ECG indicating a STeMI . For emergency medical personnel we treat it as a \'heart attack.\' The largest hypothesis is the myocardium typically metabolizes fat and during these events the myocardium instead tries to use glucose . Since this is an emotionally stressful event heart rate increase meaning the heart works harder using more glucose instead of fat . The issue is we see that the heart is not getting the necessary components for metabolism which is glucose + oxygen → carbon dioxide + water + energy In a typical MI a thrombus prevents oxygen reaching the myocardium creating strain and an acidic environment due to the lack of oxygen. This is similar since the heart does not have enough sugar to continue doing work. It is similar to a hypoglycemic patient but the low blood sugar is localized to one spot rather than systematically. The heart usually resolves this issue with out medical intervention, but there have been cases that I'm which they were suspicious of death due to Takotsubo Cardiomyopathy. Source Medscape AppStress is always stressful. Having a severe emotional event will put a strain on a system. They are in the age group of heart attacks. It is not so much chemistry as the extra strain in a vulnerable population. Without the death the heart attack could have occurred anyway and be less noticed, double events are always noted. It might have occurred a few years later but was precipitated by the strainTakotsubo is what you are asking for. An MI is a clot in an arterery supplying blood to the heart. Takotsubo mimics an MI but is really just the sides of the heart closing in on itself. Takotsubo =broken heart syndrome and is not true ischemia I believe.

That feeling when your on a Roller Coaster and you go over a hill.

you're* The feeling is you feeling lighter because some of forced caused by your momentum is still going in the upwards direction for a short period, cancelling some of the force caused by your weight.

the difference between Ethnicity and Race (i.e. hispanic)
|
Because Hispanic isn't a race. There are Asian Hispanics, there are South American Hispanics, there are black Hispanics, and there are Spanish Hispanics. If you/your ancestors spoke Spanish, you put down Hispanic. For race, you put down what your race is. This could be white, black, southeast Asian, or any other type of human under on the planet.

How do pinhole cameras work?
|
If you can imagine the camera in the shape of an hourglass, with the pinhole being the center of the hourglass, it's a lot easier to visualize. You can think of light rays traveling in a straight line, and every light ray that passes through the pinhole gets projected onto a surface, only it's in the opposite position with respect to the pinhole. Since all of the light rays do this, an image appears on the surface, but flipped upside down.

How did Russia breach international laws?
|
Article 2 of the U.N. Charter prohibits states from engaging in any threats or uses of force against other states, of which Russia and Ukraine have signed and are members of. _URL_0_ The problem with international law is that it is nearly impossible to enforce or pass judgement on. It is purely a basis for argument and peace.

When a surface is sticking to another surface (like tape) what is actually happening?
|
So there are a lot of [intermolecular forces] adhesives like those found on tape are very good at forming interactions with themselves and other surfaces. They are technically highly viscous liquids just like sugary things like syrup you might spill on your table.I would go with yes that they're both the same process. It's all about affinity. You ever heard of chrometography? It's the separation of solutes in a solution by some sort of qualitative process. So, if I have a really polar substance, I can put on a really polar filter and the substance I want will stick to the filter. It's all about like molecules attracting like molecules. The stronger that attraction the harder it is to separate certain things. That's why grease will stick to a plate or pan, it's attracted to soap but it's also attracted to the plate and the soap might not be strong enough to rip the oil molecules off the plate thus they stick. I hope I'm helping lol

Why does selling college handwritten notes qualify as copyright infringement? (Why or why not)
|
This [University of Maryland] site does a good job of explaining why. On a related note, back in the late 1990s, my university was pressuring professors to convert their courses into web-based versions. Many professors were against this saying, "If I do that, then the university can get rid of me and just pay any numbnut off the street a pittance to oversee it." This fear was not unfounded, especially for those who put a lot of time and effort to create good course materials. I stopped following that issue after I graduated, but clearly the universities recognized what they 'd lose in the long run if they did this.

Why does whipping cream make it fluffy?
|
The whipping action forces air into the cream, where it gets trapped. The trapped air is what makes the cream light and fluffyThe protein molecules in cream have formed formed a gel matrix, or foam, by being repeatedly beaten and whipped, which allows it to denature slightly. This denaturation allows tiny pockets of gas or liquid to become trapped in the matrix, which gives it a fluffy, light texture. Source: Food Science Major

Why do planes crash into each other when they have so much open sky and space to fly in? When I look up at the sky, it seems almost entirely clear of planes.
|
Almost all air accidents happen near takeoff/landing where all those planes are in a tight area. There is a very narrow path to use a runway. That said, air accidents are EXTREMELY UNCOMMON. You're safer on a plane than you are in your own car, by a huge margin.

Why do people have different voices?
|
Vocal chords vary in shape and size which vibrate with air to produce sound. Think of these like a guitar string. Changing the string changes the sound. Head and facial shapes are different. The cavities in the head affect the way sound reverberates. Imagine taking the same strings from an instrument and attaching them to a different one. The way the string vibrates and the pitch don't change but the tone does. People have different mouth shapes so the physical ways they move their mouth are different when forming shapes to make sounds. Socially, people sound different. Geographically, like with accents, but also some languages are tonal, which means the pitch affects the meaning. Have you ever noticed that women tend to speak in a higher pitch on the phone than in person but men are less likely to? Social differences. Because there are multiple factors affecting speech, it's uncommon for people to sound the same, but identical twins often do because they have similar heads, faces, body sizes, and upbringing.Physical differences in the bits of your body used to make noise with your mouth. In particular, longer and thicker vocal cords give you a deeper voice, which is why men have deeper voices than women and children.

Black holes. Ive watched lots of videos but still cant rap my head around them. Explain like I am dumb 5 year old.
|
The traditional method of black hole creation is in supernovae. A supernova is when a massive star dies. When a massive, well, massive star goes supernova the forces acting upon its core crushes it until it becomes really small. This means there's a lot of matter in a really small volume. Now, gravity is caused by mass. The force of gravity you feel depends on your distance from the centre of mass. In a massive object that's really small its gravity is concentrated in a really small volume and so you can get really close to the centre of mass before reaching the object. In black holes this means there's a distance at which the gravitational pull is so strong that even light can't escape. They're called black holes because no light is admitted from them. And holes because once you fall in you're not coming back. If you could crush the Earth down to about the size of a marble it would turn into a black hole. However, the Moon wouldn't get pulled in because it's still the same distance from the centre of mass as it always was and thus doesn't feel any increase in gravity. You would have to travel past where the Earth's surface used to be to feel an increase.

Why isn't Russia considered a part of Europe. Geographically, most of their citizens, and even their capital, are on the European side of the country.
|
Russia is a part of Europe. It's also a part of Asia. Or are you asking why Russia isn't in the EU? That's a whole separate question.Russia is obviously Europe. FFS it was part of the holy alliance _URL_0_. Anglophone countries seem to know nothing about Europe. The Slavic ethnic group is European. The Russian Language group is European. There are more blonds in Russia than there are in France, Spain, or Italy. _URL_1_ This notion that Russians are some how not "ethnically" European or that Russians are mixed, is ridiculous, and blatantly not true. Having said all that. If you mean "Western" when you say European, than no, they are not. Western would entail having undergone the cultural phenomena of the ren and the enlightenment. Russia did neither. Russia has never really entered modernity, or at least not in the way the West did. It is truly culturally unique. But, it is most certainly not Asian.I thought that most people do think of Russia as being a European country. Although I can't say I've asked many people whether they think of it as European or not though. I'd say it's primarily European for the reasons stated in the question. I'd say it's also historically European. Their expansion into Asia really happened around the same time other European powers were starting their empires. Russia just decided to just go straight east to start expanding their empire rather than going overseas like other European powers did.

Can someone ELI5 why this water simulation works very well in a web browser, but is hardly used in video games?
|
Although this water simulation works awesome you have to be careful when using it on a larger project. The first thing to notice is the number of polygons or shapes used in this project. This whole project is simply a cube and ball. This makes the program use so little cpu because there are less polygon to render Marcus from Gears of War was around 15,000 Polygons and with enemies there could be lot more. This would increase the processing power needed and make the game run slow.

What is the deal with Dubai?
|
Oil money. Then they leveraged that oil money for credit to build up Dubai, initiating a huge slew of construction projects . Some of these building projects are so ostentatious and excessive that people took notice. They have been building a Las Vegas in the Middle East . However, with the recession that hit in 2007, they lost a ton of money and have been unable to sell a lot of what they built. They've had to take a huge loan from their neighboring Emirate cities.Dubai won the oil lottery. Then they were like "fuck it, lets buy all the things." Now they're running out of money.This may not be relevant to your question, but I visited Dubai about 5 years ago and I thought it was a really strange place. There was construction everywhere. And I really mean EVERYWHERE! There were several trucks carrying sand to and from the construction sites for the man made islands. My friends went on about the crazy rich sheiks who dunno what to do with their money, the crazy laws and gender inequality. The place seemed really conservative and modern at once. A tour guide told me that the crime rate was really low. I dunno if that's true though. If it is, I'm not sure if that's cos they have shit tons of money or if it's cos they have such crazy laws that you're screwed for all eternity if you get caught doing something illegal. There's a really good article about the dark story behind Dubai. It's shocking! I can find it if you really want it. PM or respond to me if you do.

why units of time are universal across modern cultures and languages
|
Probably because once the first working system was developed it was adopted and spread all over .. Most cultures will probably have time units that are derived from periodic events, like the rising and setting of the sun, the phases of the moon, and the movement of the planets. However counting these particular cycles are not uniform or standardized across any particular culture, for example the whole 2012 bullshit craze deals with an ancient calendar that uses different time units than ours. Also things like the Ke are different than seconds. The main reason why we dont see really small time units is probably because of the difficulty of counting really small units of time with out modern technology, they could construct water clocks that are accurate to the minute, but not to the second, so they probably wont have a word for second, as they cant really express the error involved in counting a minute

How were photographs edited prior to advances in editing software? i.e. those old photographs of Stalin where people were phased out
|
For that kind of thing, they literally used an actual airbrush -- which is why photo editing software has "airbrush" tools, and why we use the word "airbrushing" to mean both retouching of photos and the practice of excluding people or events from the history books. A skilled artist using a small airbrush would paint over the object that needed to be removed or manipulated. Usually it was small things like unsightly objects or skin blemishes : the removal of entire human beings from photographs was rare and extreme, but as you say there are some famous examples of this during and after the Stalin eraThere are multiple techniques you can use for manual/"analog" retouching, pre-exposure , during exposure , and on the print , to name a few. As for the disappeared persons in Soviet photos: they were airbrushed away.

Why are realistic CGI movies so expensive to produce?
|
As with most things expensive; it's difficult, it takes time and it requires a lot of resources. For one scene of CGI it might be months of work behind it, with everything from motion capture actors , scrubbing of the motion capture data, creating all the 3D models, painting or creating textures and mattes, staging it over and over again until it's to everybody's liking, hours of rendering and then painstakingly handcrafted finishing polish to create the last touches.

Why Germany decided to go Nuclear-free
|
Well, although Germany is not as seismically active as say Japan, there is seismic activity there which can be a cause for concern. Overall, I would say Germany made the decision because there is a strong environmental movement in Germany. Germany has already started building wind farms and is big on solar technology both because they are a technological and industrial powerhouse. Germany already had a law on the books to phase out nuclear energy until the lifespans of the nuclear reactors were lengthened by the current government. The lengthening of reactor lifespans was highly controversial here with a huge segment of the population being unhappy about it. When Fukushima happened, the government made an about-face on their plans. Since the reactor life extension was already unpopular the government figured it could try to save face. As to why the anti-nuclear movement in Germany is so large, there's a simple answer. Chernobyl. When Chernobyl exploded the radioactive cloud went right over Germany and Europe triggering the movement.

Why is there muscle strength loss after surgery?
|
Fun fact muscles are always in decline. Muscle cells are always dying off, body is always consuming mcules for energy. But the body replaces that if you use them, if not, body doesn't have a need to replace "damaged" muscles. Hence the loss of strength. As soon as you start using them, the strenght returnsThe body slowly eats away muscle tissue for energy and muscle cells die and are removed. Because you aren't using the muscles there is nothing to trigger the growth of new muscle tissue so it "wastes away "
