Why can other animals eat raw meat from a corpse but humans cannot?
|
We can! The danger comes form they way the meat is prepared before it is given to us. America is notorious for poor regulation of sanitation standards for butchers and farmers. In America it is just safer to assume your meat was poorly handled and contaminated, because it most likely was/is.

Relativity (also difference between general and special) as well as string theory
|
Special relativity: The speed of light is the same in all reference frames. You can't accelerate to the speed of light. You can't travel at the speed of light unless you're massless, in which case you must travel at the speed of light. Time passes differently in different rest frames. General relativity: As above, plus gravity is the effect of curvature of spacetime around massive objects. This is why it affects massless things like light. String theory: Trying to describe reality in terms of tiny vibrating strings. If successful, would overcome existing problems in relativity and quantum mechanics where these two fields are not compatible. Would be a leap ahead in our understanding of reality. But currently makes no testable predictions. If you want to know more, search. These things are asked all the time. If you want a more helpful response than that, ask a specific question; we have no way to know what your problem with the existing explanations is.

If weight gain/loss is as simple as energy in versus energy out, how do some competitive eaters remain slender?
|
They are not eating contest level calorie numbers as part of their normal diet. When they train they eat lots of low calorie high volume foods like cabbage and lettuce and drink a lot of water to stretch their stomachs and only eat the contest meals a few times in training for the competition. The occasional massive intake of calories will not make you massively fat, the consistent intake of them does. What they do is not much different than a Thanksgiving or Christmas feast.In addition to eating low-calorie foods when preparing, there are also no rules against them puking up all that food after competitions. And I've read that a lot of them do vomit that crap up once finished.

Why is there sometimes a slightly enjoyable "shiver" after urinating?
|
Well, I don't know if I'm doing this right, but since I've wondered myself, here's what I found so far: > According to Sheth, our parasympathetic nervous system lowers the body’s blood pressure “to initiate urination.” One leading theory behind the shudder is that peeing can unleash a reactive response from the body’s sympathetic nervous system . > On the cellular level, the body is theoretically flushed with catecholamines . Those are dispatched to help restore or maintain blood pressure, Sheth says. But the microscopic energy bullets “may also trigger the shiver reflect.” I know this isn't the 5y-old explanation, but it's the best I can find. Maybe someone else can put this into laymen's terms :) Source is [NBC News], I have no idea how reliable they are.

How does motion interpolation work?
|
There's a million approaches to interpolation. One is: have a good algorithm to find consistent "control points" on the image. Corners on places of high contrast, etc. Notice how those control points move between frame 0 and frame 2. Calculate a new intermediate frame by taking the average of and . Another is : Train a neural network to try and predict frame 1 given frames 0 and 2 on real 60FPS sources.

what does an equalizer do? Why do I need it on my computer?
|
Sound is made of pressure waves. The sound that comes out of your speakers is a combination of waves of all sorts of frequencies. The higher the frequency, the higher pitch, and lower frequency is lower pitch. The equalizer is kind of like a volume control for little bits of the spectrum of frequency that the human ear can here, so you might turn up the low end if your speaker has poor bass response and normally requires you to turn the total volume up in order to hear the bass well. edit: Also, regarding Boom, Windows has a system-wide equalizer, so you can make changes that will get affected whether you're playing music through your web browser or itunes or vlc or whatever, rather than just the itunes equalizer which only affects itunes. OS X doesn't have one built in for the whole system though, it's up to individual apps to provide you with specific EQs, so this would alleviate that by giving you a system EQ

Why do we know very little about sleep/dreams?
|
Dreams are entirely subjective, usually with no outward signs to gather info from. We've only recently started creating machines that can read our brains to help us learn more about mental processes. To contrast, we've had thousands of years to study the rest of our bodies.

Why is it that certain toys are hard to find? Why don't they just make enough?
|
They don't always anticipate the demand and are afraid of making too many. Nobody wants to be stuck with merchandise they can't move. This is why they'd rather err on the side of caution and not make enough than to make too many and lose money that way.

Why are metals with low melting points (eg mercury and lead) more poisons or harmful?
|
They're unrelated. Gallium, indium, bismuth, sodium, potassium, rubidium and caesium are all metals with low melting points that aren't particularly toxic. Gallium melts slightly above room temperature. You could have it melt into a puddle in your hand and suffer no ill effects. Indium is a soft metal that melts below 200 C. It's not particularly toxic. Bismuth has a melting point below that of lead. It's non-toxic to the point that pepto bismol's active ingredient contains bismuth. Sodium and potassium have melting points below that of boiling water and both are essential to life. Rubidium and caesium are not very toxic. The toxicity of their compounds is comparable to table salt.

In purely practical terms, what is life like for illegal immigrants in developed western countries? Can they drive? Get married? Have children legally? Get healthcare? Get a job?
|
I've worked in construction in Toronto for 12 years alongside illegal immigrants from all over the world. Typically there will be an ambitious worker that will take the lead and find a way to get a driver license, SIN or a business number, and start to get work contacts and hire other workers. Those people tend to get by very well, but the hired workers are often given just enough to get by and treated unfairly. It varies from crew to crew so that may be an unfair assesment, but it's the most common situation that I've seen. When it comes to renting an apartment, getting married, and living life in general, almost all of the people I've known have had no problem, but have told me they're always looking over their shoulder and are terrified any time a cop car drives by. I knew a guy that stitched himself up cause he was scared of going to the hospital. It's much better to immigrate legally, sometimes countries will ban you for life if you're caught.

Why are sites such as Netflix and Youtube able to stream high definition video on relatively slow internet, while other sites struggle to stream that same quality of video on even the best internet?
|
Compression is a wonderful thing. When you go to Netflix or YouTube, you aren't actually streaming 1080p or 720p. The feed you're getting is highly compressed, and your computer then renders and upscales it once you've received it.* Netflix partners with ISPs and locates their content servers *inside* ISP facilities. This means your Netflix video doesn't always travel across the internet to get to you, it only goes from your ISP to you which is a dedicated hi-speed connection. * Netflix uses video compression to reduce the amount of data being sent to you. You don't really notice it because it's very good and also because most video you watch is compressed and you're used to it. Both cable and Sat TV providers use video compression even on their "HD" channels1) Netflix and Youtube have some of the fastest internet connections on their end with extremely high traffic capacity. 2) Netflix and Youtube have good compression algorithms that lets their streams take up less data mid transit and are decompressed on the watchers end. 3) They both have tiers of quality and do not actually allow their HD video to transmit to people who have too low of a connection.

Why, when most people orgasm, they instinctively want to vocalize their excitement/expressions?
|
No scientific answer here, but I can only assume it is like any other "unexpected" rush of emotions or feeling. When you step on a nail, you shriek. When you burn your hand, you shriek. Just like anonoman925 said, it is probably an involuntary reaction to too much stimulus. TL;DR: Too much stimulus = Involuntary reaction.

Why do we attribute some quotes to characters, while others to the author?
|
The difference lies in whether or not the quote is representative of the ideals and opinions of the author. Is it something the character just says, or something the character believes , or is it something the character said because the author was deliberately using them as a vehicle for expressing that idea? Also, it could just simply be an incorrect citation.It probably has something to do with how memorable the character is. When you have a fantasy story with deep character background and which is also quite memorable — as is the case with Gandalf — it feels much more natural to think of the character as a real person rather than as pen on paper written by the author, especially when you also have film adaptation with said characters. On the other side, when you have less character depth and focus, you tend to think of the text you read as coming from the author rather than the character itself.Usually, at least for me, if it's a character's dialogue, I'll attribute it to the character . If it's in narration, I'll say the author. I can sort of agree with your choice to quote the author rather than Calvin in that instance, but I think that's slightly different than quoting from a large novel. Calvin can be seen as a stand-in character for Watterson to express his philosophical and playful thoughts. Gandalf was a character in an epic tale, so anything he said would be his voice, not necessarily the author's.

What are the concepts of intrinsic value and instrumental value in philosophy?
|
Intrinsic value is when I value something for itself. Instrumental value is the "I can use this!" sort of value. This is a tool that lets me better get what I want, so it's valuable to me. I value the well-being of those I care about, for instance. Is this so I can get something else? No, I just want them healthy. I might admire an art and want it around because I like it, and not because I can use it to get or do something else. I value having shoes because they help me get to work -- shoes are a tool that gets me to work better. I value work because it's a tool that gets me money that's a tool that I can use to get shelter and food and healthcare and stuff. It gets a bit fuzzy between "I want this because it will have a mental effect on me" and "I want this for itself". I tend to be a bit generous here -- for instance, I have a cute hair clip, and I value it because it helps me look cute. That's pretty close to the outside world / internal mind divide, so I 'd say that I intrinsically value that hair clip. But another person might say that my intrinsic value is on being cute, or feeling like I'm cute, and the hair clip is a tool that helps me achieve that goal. Except it was also a gift from my spouse, so I value it for that reason too. Things are complicated.Say the only thing want in the world right now is some chocolate. That has intrinsic value, it's all you currently value. But there's a second class of things you value, things that allow you to get chocolate. So in this situation money would have instrumental value, because it allows you to buy chocolate. So you want money, _but_ you only want money to get chocolate. That's the difference.

What are the advantages of using a Bullpup-Style rifle over a conventional one?
|
Bullpup rifles provide barrel length of longer rifles, but overall length closer to carbines . The barrel length helps increase bullet energy and long range accuracy, while the shorter overall length makes it more manageable, especially in close-quarter fighting.

How does our nervous system work in regards to how we feel through the use of neurotransmitters and medication?
|
Please note that a lot of our information about neurotransmitters is correlative, not causative. We know certain neurotransmitters correspond with certain conditions. We know that the lack of them, or an excess of them can be correlated with certain disorders. For example, dopamine is linked to movement, learning and motivation. Too little dopamine has correlations with jittery movement . Too *much* dopamine has correlations with schizophrenia. A lot of medications for mental disorders try to help by either reducing or increasing the amounts, rates or absorption of neurotransmitters. The thing is, a lot of times this is guesswork, and a lot of times you have to really trial-and-error it. Say, for example, we have someone diagnosed with schizophrenia, and we want to treat it by reducing dopamine levels. Reduce it *too* much and the person's movement can be affected. Not enough, and you're not helping the patient. And possibly dopamine levels weren't at fault to begin with, so you have to try other things. As for the withdrawal thing - that's pretty anecdotal, but imagine living with depression , and then *not* living with it for a while, perhaps an extended period. Feeling that all come back that can be incredibly harsh.

Does "nothing" exist?
|
It depends on what you mean by "something." Considering physical reality, there is a minimum size a 'thing\' has to be in order to be considered 'real\'. We can talk about Planck lengths, quarks, and leptons all day, and we can even toss around numbers like 10^-35 metres until we're blue in the face, and it misses the spirit of your question. There's an amazing discussion about the nature of "nothing" and whether we can consider it to be "real" in one of the Isaac Asimov memorial debates. Take a look when you have some time, because I think this at least touches on what you're asking. And even if not, it's a truly breathtaking and fascinating discussion. Pay close attention to Lawrence Krauss\' answers, because of all the physicists I 've heard discuss this question, he seems to make the most sense to me, a hobbyist/layperson like yourself. _URL_0_ edit - I 've heard cosmologist Sean Carroll say that the default or 'typical\' state IS nothingness; that, in fact, existence itself is a mathematical improbability. Now, I'm fairly certain he's equating \'nothing\' with a thermal equilibrium state and his definition is sort of limited to the idea that in the absence of events , we can consider such a state to be "nothingness." But this is more of a 'mathematician's answer,\' if you will. It's technically correct but again misses the philosophical spirit of your question.

How does the finding of 2 new subatomic particles affect our understanding of the universe?
|
I'm assuming you are referring to this _URL_1_ Particle physicists make their predictions from the Standard Model _URL_0_ It's really the best theory we have to explain the particles and forces we see in the universe. And like any good scientific theory, we can make predictions. These particles were predicted to exist and their properties could be calculated. So we found these particles and their properties were in line with the predictions. So we really haven't found out anything new and unexpected about the structure of the universe. That sounds like a good thing, but really scientists are looking for times when they find something they don't understand. Right now we know dark matter must exist, but the properties of the particles are known from the Standard Model, so we know it must be incomplete. They are looking for anomalies which might give hints of "new" physics beyond the Standard Model. And it is believed that more massive particles will couple more strongly with the dark matter giving a detectible signal.

Musical forms, codas, del signo, Middle 8's (MUSICIANS OF REDDIT)
|
Let's start by saying that a coda is an ending to a piece or movement of music which doesn't follow linearly. By that I mean you don't play the music measure 1, measure 2 . measure 64, CODA! Instead, the sheet music tells you to repeat a section of the song, and then instructs you to jump to the coda. There are 2 common ways for this instruction to happen. Da capo al coda, or DC al Coda, is Italian for "from the head to the tail." When this instruction shows up in music, you move to the beginning of the piece, play until you see the Coda symbol and then jump to the coda. Dal segno al coda means "from the sign to the end" and just means that instead of jumping to the beginning, you just jump to the segno symbol. Then you play until the coda bullseye, then play the coda. Both instructions are the composer saying "I want people to hear the best part of my song again, then hear this cool ending I wrote." Whether DC or DS is used depends on whether that best part is the beginning or somewhere in the middle. A middle 8 can absolutely be 16 bars long. Middle 8 just refers to a bridge in ballad form songs and later songs that developed from it. If you have a section in the middle of a song, in a very different key, different dynamic or otherwise very distinct from what comes before and what follows, middle 8 is most often a valid way to describe it.

Why is the movie Frozen seen as a metaphor for homosexuality?
|
Elsa has a condition that is shameful, and that her parents want her to hide and never let anyone else see. If they could cure it, they would, but they can't. Elsa suppresses her feelings and lives a sad, unfulfilled life hoping that no one figures out the truth about her. When people do find out, they react poorly, and she runs away. But then Elsa decides that she's not going to hide who she is anymore, and lie to herself. She's going to Let It Go and be free, changing her style. At the end, Elsa finds happiness and realizes that people will still love her even if she is different. So yeah. It's a metaphor for being different and alienated, and being gay is an example of that.

why did animals grow larger in the past? Is this because of human development? It seems like sharks, birds, turtles, snakes, etc. used to be a lot bigger
|
We are a short period since the last mass extinction event. Small animals flourished because of the conditions and have been evolving since. Some of the largest animals you see now are survivors of that mass extinction. There just hasn't been enough time passed to let evolution take it's course and allow for much larger animals to grow. In theory, there is no reason that in a few million years there couldn't be animals the size of dinosaurs again.

Why do companies put so much value into the price of their stock on the secondary market?
|
A few reasons. 1. They have a legal duty to do their best to deliver a positive return for investors. 2. Issuing more stock to the market is a good way to raise capital. For that to work, you have to have a high stock price at the point at which you sell your stock. 3. Many companies' executives are paid, in part or in the majority, in stock options or directly in stock. > I guess they could issue more stock but wouldn't that be bad for current stock holders if their shares become diluted? Yes, but that depends on what your goal is. If you want to just increase shareholder value forever, then you're right, it's a goal with no real reason behind it . But companies know that funding important expansion is more important than keeping a stock price high. It'd be like stocking up on canned food for the Apocalypse, and then refusing to break into it because you are afraid of running out.

Why do some memories get stronger with repeated thinking and some weaker?
|
Typically, accessing a memory will strengthen it. But there's a catch. Research has shown that accessing a memory causes it to be re-written back into our long-term memory. This helps to preserve it. Memories which are rarely accessed tend to slowly "fade" over time, and accessing a memory combats this characteristic. But it is possible for us to actually *change* memories during this process. If for some reason we think that some detail of the memory is wrong, we can re-write the memory with that detail changed. We essentially corrupt our own memory. This is actually good in some cases. For example, there's work being done to help victims of PTSD actively forget or change some memories to help them. Of course, it is not so good when we recall something like an argument we had but change the details to make ourselves come off better. When it comes to speech vs. sunset, I 'd speculate that the difference is that a speech is a distinct thing, whereas a sunset is a rather nebulous image with few details for us to latch onto. But I'm really just guessing at this.I'd say state of mind. Why else would dreams be so vivid and 20 minutes later no recollection of what the hell happened.

Why aren't leaves the same color as solar panels?
|
Of course chlorophyll is the obvious answer, because it reflects green light rather than absorbing it. But the next question is "why isn't chlorophyll black?" Some say it's because the plants would absorb too much heat that way, but that might not be true for all or even most plants. The answer may be because plants evolved from a single algae ancestor, and chlorophyll was present in that and met the needs of the plant descendantsSeeing as plants are biological and use the sun to change light in to starches and oxygen. And. Solar panels use photovoltaic cells to change light in to electricity. I would venture a guess that its the material they made from and not the color thats important.

Why are the URL Addresses for Reddituploads so long?
|
it guarantees that it's a unique URL. the first section is most likely the asset key. that info identifies the content that needs to be fetched. when you're dealing with hundreds of millions of different files, each one needs to be uniquely identified so it can be fetched. second reason is that it hides the original filename that the user used. some people might forget and leave personally identifiable information in the filename.

Why would anyone pay money to subscribe to someones stream on Twitch when it's already streaming for free?
|
Because Viewers know that Twitch Streams are not free. Someone, somewhere, is creating the content and spending time doing so. If they never have any payment for doing so then they will stop doing it. This could be because they are annoyed at not getting paid or because they simply cannot carry on doing whatever it is that makes the stream watchable. Much like the collapse of Social Networks such as MySpace: there is a limit to the amount of free content that people will provide.They don't pay to follow, they pay to support. It gives the streamer an incentive to keep going. And if you're willing to pay $10 for a film you're willing to pay $10 for hours and hours and hours of interactive streaming", 'The phrase you are looking for is human decency.If you find somebody entertaining, then giving them a little bit of money each month is way to increase the chances that they can afford to carry on doing it. This is particularly true for the professional streamers. People like JP McDaniel, Towelliee, and Trump stream as a job. They couldn't do that if it weren't for their subscribers giving them money. You might not find streamers entertaining enough to subscribe, or to watch for more than 10 minutes at a time, and that's absolutely fine. Nobody says you have to love streaming or contribute financially to it. My personal favourite pro streamer often makes the point that subscribing is a bonus, and that nobody should ever feel pressured to do it. But there are plenty of other people who find watching a streamer to be more enjoyable than watching TV or a movie. To them, it's worth dropping a few dollars a month if it means that their favourite entertainment continues to exist, or even improves because of the extra funding.

How would China devaluing its currency affect dollar denominated debt?
|
China devaluing their currency would have the benefit of reducing the world market prices for their exports, boosting economic growth, but will make foreign currency denominated debt more expensive to service, since firms will need to spend more RMB to buy the same amount of dollars to service their debt. For an individual firm, if the increased cost of debt isn't mitigated by increased export sales, this policy can drive reduced profitability at best or insolvency at worst.

Why can Google search the Internet faster than my computer can search itself?
|
While many of the answers that include a statement like "They have lots of computers doing parallel computation" are correct to some degree, there are other factors. When your computer searches itself it must visit every file in the computer. However when google gets a search query it generates a search vector. This vector tells their algorithm to only search in a certain direction. Think of all the data google has as a tree. If you send the query "Why is the sky blue?" the search vector generation algorithm will recognize that the information you are looking for is stored in a few of the roots of the tree, therefore they will only search through the few roots that the search vector tells us to and then return the results. Then the amount of available computation they have relative to the amount of information that needs to be searched is a much higher ratio than your computer. Where-as you have 1 processor searching 1000's of folders on your computer google has 1000's of processors searching 1000's of folders.You'd be surprised how many searches on Google are pre-indexed. So not only does Google have a metric shit ton of computers, those computers have a metric shit ton of previously and often searched terms queued up and waiting for the next person to ask. These terms are re-searched and re-indexed often to make sure you get the latest info possible,

Why console gamers and pc gamers cant play together in matchmaking?
|
Simply, the console players would get crushed. The amount of finite control a mouse+keyboard offers over a controller is pretty apparenti agree with everyone when it comes to FPS but many other games have no excuse for not being cross platform. racing games and fighters come to mind.Everyone that has posted in this discussion is correct. I'll just add this as a question to counter your question: If xbox/ps3 players can play as well as PC players, why do they have autoaim on public games? Obviously, the answer is that they can't play as well. The control surfaces are simply too shitty and imprecise. As a long-time PC FPS player, I could never make the leap to console FPS. It feels like someone cut off my fingers and told me to play using my stumps. I HAVE tried to play both ps3 and 360 , and while my K/D was decent, the game simply was not enjoyable. Once you learn to play FPS on PC, you'll understand why.

Why do viruses kill living things, if they need a living host to continue to exist?
|
Accidentally. Often, it doesn't actually end up killing enough hosts as to prevent the spread of the disease, which is what makes them continue to exist. For example, if it made a person explode violently into billions of tiny airborne particles which would then be easily inhaled by other people, and it lay dormant in a person long enough for them to have a baby or two and raise them before it "went off", then it would work just fine at continuing to exist. What you're asking is basically similar to asking "If carnivores need to eat other animals to continue to exist, why do they kill those animals?"', "Evolution is blind. If they can spread even if the host died, it can evolve that way just fine. If killing the host stops it from spreading then it'd die out.
|
Why do I function less when I get more hours of sleep than usual?
|
There are two main factors at play here: 1) Your body likes consistency. If it's used to getting 6 hours of sleep, it expects to get 6 hours of sleep that night, and will regulate its daily hormonal cycle accordingly. Messing with that in any way, even if it provides more rest, will make your body confused and stressed. 2) Humans have cycles of sleep that last ~90 minutes. Waking up close to the end/beginning of a cycle leaves you feeling refreshed and alert, while waking up in the middle makes you grouchy and tired. 6 hours is 4 full average cycles; sleeping exactly 8 hours is 30 minutes into a new cycle, and therefore undesirable. If you want to get extra rest, try for 7 hours 30 minutes or 9 hours.

How can congress sneak CISA into the NASA bill?
|
Congress makes its own rules. There are very few rules for Congress in the Constitution. The rest they write themselves. They can even ignore rules they write if no one in Congress objects.It's called a rider, and it's actually a fairly standard operation that happens all the time. It's just that it only makes the news when it's controversial bills that are getting stuck together. When a bill is in the House, any amendments to it have to be germane to the content of the bill. After it makes it to the senate, it's a lot less stringent. A couple examples: The majority party in the senate wants to pass Bill A. Bill A is controversial in the party, and there are enough senators in the majority party that do not support it that it won't pass if it comes to a vote. The Minority party has Bill B , which they unanimously want to see pass, but the majority party isn't in favor, so it also won't pass. If enough members of the majority think that getting Bill A passed is worth having Bill B passed, and vice versa from the minority party, then they will amend Bill A with Bill B as a rider and vote to pass it. Another example which might be the case here is a power play by the majority senate party against an opposition president. Take a bill that is widely regarded as necessary, like an appropriations bill, and attach a controversial rider. After the bill passes the senate, it goes to the president's desk to either be veto'd, or signed into law. The President doesn't have the power to veto only a portion of a bill, so his choices are to either sign the bill and allow the rider he doesn't like, or veto the bill and send it back to congress while taking criticism for blocking the original appropriations.

Why do different countries drive on different sides of the street and choose to have the wheel on a different side of the car?
|
The side of the road people drive on is due to most people being right handed and the most common form of transportation at the time the rules were decided upon. A horse drawn cart would have the owner walking on the left side of the horse holding the reins with their dominant right hand. When passing another cart, you would keep to the right to keep your body between the passing horses for control and to see clearance. In other areas if you were riding a horse drawn carriage, you would sit on the carriage with the reins in your left hand and the whip in your right dominate hand as that requires more control. If you sat in the middle or left side of the carriage, you would whip anyone sitting behind you so you sat on the right side of the carriage. When passing another carriage you would pass on the left so again you could see clearance as you passed. When the rules were decided, it was based on what most people were doing at the time. Over time some countries have changed to be more compatible with their neighbors and to reduce accidents. Most of the countries that still drive on the left are island nations that have little incentive to switch. Driving on one side of the road is not better than another but regardless what side you drive, you will always be on the inside to watch for clearance as you pass another vehicle.The driver's position switches because it gives him longer sight lines and better overview of the most relevant traffic around him - it's easier to see and yield to traffic from the right if you're on the left side of your car, and easier to see traffic from the left side if you're on the right side of your car. The choice of left- or right-handed driving is arbitrary and is mainly decided by tradition and law. Continental Europe is mainly right-handed thanks in part to Napoleonic France imposing that law on their conquests, much of the former British Empire is left-handed, and so on.

Why do conspiracy theorists often claim that there is significance to words/phrases being spelled/played in reverse?
|
Conspiracy theorists, almost by definition, find patterns in things that are not patterns, or logic in things that are not logical.It stems from a belief that was popularized by Christian fundamentalists during the Satanic Panic in the 80s, that if you say something backwards it will subliminally implant itself in their mind and brainwash them without realizing it. There's no real science behind it.Because they take the fundamentally fallacious approach of determining the outcome first, and then looking for the supporting evidence afterwards. This is compounded by a relatively low standard for admitting something into evidenceJackKevorkianJackianianiilluminatinice try, illuminati

Why do you feel full faster if you eat slower?
|
It takes some time for the chemicals responsible for fullness to be released and move from the stomach to the brain. When you eat slowly, these chemicals are released gradually and so your brain's levels of them rise gently. When you eat quickly, you suddenly shift from no fullness to tons of fullness, but it's delayed.

Why is tomato a fruit but not a chili?
|
It depends if you are talking about cooking or if you're looking at it from the scientific perspective. Here's the scientific view: A fruit in general is the vehicle that angiosperms use to distribute their seeds. That applies for tomatoes as well as for chili. Apart from the "obvious" fruits like apples and bananas, all kinds of "beans" , cucumbers and pumpkins, even wheat grains are fruits. In botany, fruits get classified mostly according to their morphology and their development. Usually, a fruit contains the seed which is often surrounded by an outer layer - the pericarp. The pericarp is sometimes fleshy and edible - thats what most people outside of botany refer to as "fruit". There are many different kinds of fruit morphologies and compositions. For example, some fruits contain a seed surrounded by a hard shell - those are called nuts. Peanuts, Chestnuts and Acorns are botanically nuts, while coconuts are not.Things like strawberries are composed of many tiny nuts embedded in a fleshy tissue - in fact, all those tiny nuts developed from different ovaries, the fleshy parts however did not develop from an ovary. Things like that are called aggregate accessory fruits. Botanically, those are NOT berries. Berries, in the view of botany, contain a pericarp , that developed from the outer layer of a single ovary. Per definition, bananas, cucumbers, grapes, pumpkins, melons are berries - as well as tomatoes and chilies. So, in summary, tomatoes and chilies are both fruits. In fact, they are even the same kind of fruits, which is a berry. Disclaimer: I am a biologist, but not a botanist. There may be mistakes in my explanations and if a botanist wants to correct or confirm my statements I 'd be grateful.

Why is it colder inside a plastic bin than the surrounding room?
|
I assume the bin has a lid to keep the pretzels fresh? So 1) you have air trapped inside there that doesn’t circulate. It would pick up the ambient temperature very slowly —warming up slower than the office all day and cooling down slower than the office all night. So inside the bin it would be the same as the average of the past few hours in the office. But also it *might* be 2) inside a big bin of pretzels the humidity is going to be lower. You have salt and you have starch in there. Both will suck moisture out of the air as your pretzels become sad and stale. When you put your hot, sweaty hand in there for a treat, you might actually get your sweat evaporating faster into the dry air. This would cool off your hand more rapidly than more humid air in the rest of the office. I am honestly not sure this effect would be big enough to matter, so maybe save the bin when the pretzels are gone, put some water in there overnight and then try it. If it’s still colder then this crazy idea is not a thing.Where the heck do you work that you have a communal bucket of chilled pretzels? This whole thing intrigues me. It's likely do to working with a bunch of mouth breathers who warm the office air but not the pretzel bucket. This is good, it means said mouth breathers aren't breathing into the bucket. ", 'I’m no expert but the room itself has lights, bodies and sun warming the room. Inside the bin there isn’t any source of hear. The exterior of the bin shield the interior: hence a cooler temperatureHave you demonstrated this with objective measuring equipment? Sounds like some psychological effect to me rather than the temperature actually being lower.

Why does tapping on the top of a shaken up can stop it from fizzing when you open it?
|
This is actually a myth. The only things that affect the level of "fizziness" when you open a soda is temperature and pressure. Since you can't really alter the pressure in a can, the only thing you can do is change the temperature. Gasses dissolve more readily in colder temperature, so your best bet if you don't want a can to foam over is to put it in the fridge for a few minutes to let the CO2 re-dissolve into the liquid. You can read more about why on the Snopes article that debunked it. [Link to article]

If you pour water in front of a light, how does it have a shadow if it's clear?
|
It's not completely clear, if it were you wouldn't be able to see it. So the part that is deflecting light and hitting your eye allowing you to see it also blocks/absorbs the light and creates a shadow", 'The water still does absorb some of the light, which creates a shadow. Most glass does the same.Water being poured isn't perfectly cylindrical , and the small angles in on the water's surface scatters the light in different directions, reducing what makes it through the stream to whatever surface is casting the shadow.Also, try lighting a lighter or match, and watch the shadow. You will be able to see far more of the heat waves in the shadow and see just how far they actually go.Water has a different index of refraction than air does. Due to this, the light will bend from it's 'normal' path when it hits the curved surface of the poured water. Some of the light that was on its way to the table is now experiencing a detour, if you will. So there is a regional lack of photons in the areas where those detours occurred. A lack of photons is equivalent to a shadow. This also explains why some parts of the 'shadow' are brighter than they should be, as the poured water is basically a lens moving light from its normal path to other areas. And yes, as others have pointed out, some of the shadow effect is due to particulate debris in the water. The dirtier the water, the darker the shadow, but the shadowing effect as I explained would still occur even if the water was perfectly distilled .

Muscle contraction is the only way to squeeze blood back up from the lower legs. When sitting still, contracting the calf muscles allows the blood to be squeezed up and avoids pooling.

Why is a production possibility frontier displayed as a curve, rather than a straight line?

Because usually the marginal product cost increases as your output for that product goes up. In other words going from catching 5 rabbits to 6 rabbits is harder than going from catching 0 rabbits to 1 rabbit.

Why don't "large", sluggish animals like Crane Flies and naked snails have more enemies?
|
Slugs, at least, are eaten by a wide varity of species of all types and classes. However, like many prey species, slugs have evolved to produce huge numbers of offspring--and for slugs in particular, being hermaphrodites means both halves of a mating pair can and will bear young. I believe the average litter is around 30, so two slugs can produce 60 more slugs between them. It's also possible that human activities have disrupted and killed off some of the natural predators of these animals, which is why you're seeing a higher number than what might be considered normal.

How can game programming be so amazing?
|
> it can't be a bunch of "if" and "elses", Actually, yes kind of is. Modern languages have ways to allow you to write a lot of machine code in fewer hand-written lines of code, but essentially it all gets converted back into a set of instructions which all basically get and set register values, test comparisons, and change which instructions to do next. To make the task easier, developers tend to write libraries for other developers to use. You don't need to know the instructions to take to the graphics card because the people making the card wrote them for you and bundled them up into nice libraries for you to call. Likewise, the operating system allows ways so you can receive input and send output in relatively few lines while the complier links to libraries with many more lines of code to do those functions.There isn't really that much to explain here. It really is just lots of ifs and else's and for loops and so on. Computers are really fast, they can do trillions of individual operations a second. Games do rely on doing a lot of stuff in parallel though. So there are multiple CPU cores running code at the same time, and GPUs work by operating on lots of different pieces of data at the same time.

How does a computer trash can work ?
|
The Trash Can/Recycle Bin works like another folder until you empty it. When emptied, the computer will make the space on the hard drive taken up by the file be able to be overwritten. The file will stay there until the computer writes something over it. You can secure delete the trash on Mac, which means the computer will randomly write numbers over where the file was. For more explanation, check out [this link].If you're talking about the 'Recycle Bin' used on Windows computers then it works like a real life trash can being emptied on regular intervals files are stored there temporarily until something overwrites them or they are just cleaned away however if you put something there and lose certain programs such as 'Recuva' can help bring back your oh so precious data.

What is really going on with North Korea? Should I be worried?
|
There are many theories about what is really going on with North Korea currently and I can't come up with a definitive answer to what is going on. However, you should not be worried because North Korea and The United States and their allies know that if North Korea strikes another country with their nuclear weapons then that would mean the end of their regime. Even if they were just to target South Korea, there would be a large amount of United States military personnel there and they would suffer casualties as well, meaning an open declaration of war with the United States and ultimately their allies. North Korea does not have the military capacity to withhold a war with China, the USA, and the members of NATO. North Korea knows this as well and in most likely hood, these are false threats. Also, the range of North Korean missiles would reportedly only reach about the western United States and the USA has anti-missile defenses all around the Korean peninsula so if a missile would actually be fired, then they could be destroyed in air before being a real threat. Source: I go to a quasi-military/naval academy and one of my classes focuses on the International Relations of countries and in particular what is unfolding in the Korean Peninsula.

cars like VW Beetle proved that a motor can be refrigerated by air. Why this kind of design never succeeded to be the most popular and water/liquid refrigerated won?
|
Just because somethings possible doesn't mean it's a good idea. Liquid coolants have a *much* higher heat capacity, and so can absorb much higher amounts of heat from the engine. This is good, because the engine generally runs more efficiently as it's operating temperature increases, but this necessitates a better coolant system to get rid of the waste heat from the engine block, which allows you to get all of the positives of a hot engine, with none of the negatives.

Why is pink considered a 'girly' color?
|
It actually used to be seen as a very masculine colour, before the 20th century. The idea was that it was a shade of red, and red is a strong colour, representing passion, blood, and other such thingsFun fact: Technically, pink is not a real color because there is no such thing as pink light: [NPR: They Did It To Pluto, But Not To Pink! Please Not Pink!]It is cultural and does not apply to all countries in the same way and depending on the country colors are often associated with different things. In Thailand for example pink is a popular color, worn both by man and woman. While in Europe at a wedding the bride wears white, in china the bride wears red because red stands for love and white is associated with death/ghosts. Yellow in Asia is often associated with royalty, you will also see a lot of gold and a combination of gold/yellow and red. Often it also is purely fashion, it only takes some celebrity to stand out wearing a certain color and many will follow.

How the women's only screening of Wonder Women is affected by antidiscrimination laws
|
Title VII of the Civil Rights Act of 1964 prohibits discrimination by employers "on the basis of race, color, religion, sex, or national origin." However, Title II of the same act prohibits discrimination "based on race, color, religion, or national origin in hotels, motels, restaurants, **theaters,** and all other public accommodations engaged in interstate commerce." Congress made no attempt to enforce gender equity on the Boy Scouts, men's clubs, women's groups, restrooms, or half-way homes for "troubled" women. Gender discrimination is completely legal in the United States in many sectors. Employment isn't one of them, but theaters are.

How can there be any HD videos of WW2, when there wasn't any HD cameras back then?
|
"HD", today refers to a digital image that is 1920 pixel wide x 1080 pixels high - this is about a 2MP image. Video from WWII is shot on real analog film - silver halide crystals on film. Analog film does have a "theoretical max resolution" that it can be scanned at, and compared to today's HD picture it's very high. 35mm film is estimated to contain about the equivalent of 25MP of information - or about 6000x4000 pixels. So, a 1080 HD scan of a good 35mm analog film print is still losing about 12x the resolution of the original image .OP's next question: How did they take photographs in WWII if old rotary phones didn't have cameras?

How does a Frisbee fly?
|
Bernoulli's principle - Lower air pressure above the Frisbee gives it lift and allows it to stay up. The angle at which its thrown, spin and wind all ad to its direction.If you look at the frisbee, it looks sort of like a wing right? And it functions exactly like a wing - [air will move faster on the frisbee's top and create lift.] This is what makes frisbees fly. Moreover, the method of throwing the frisbee - spinning - will give the frisbee a lot of *stability* - this forces the frisbee to "stay upright" the same reason why gyroscopes stay upright. "Stability" is also what determines if the frisbee turns or goes straight. Depending on the angle you throw the frisbee and how much rotation you put into it, the frisbee will curve different directions. The spinning of the frisbee will bend the air and give a particular side of the frisbee more "lifting force" - [namely, the side that spins the incoming air faster.] However, you can't forget the frisbee's **[roll angle]**. The roll angle determines the direction of lift generated from the top of the frisbee's airfoil. This too will contribute greatly to where the frisbee turns. In fact, this component may counter the lift generated from the spinning. Thus, you the thrower have a lot of control over how the frisbee turns. You can even throw the frisbee in a manner where it first turns left, then starts to turn right because, say, pitch-generated lift begins to slowly dominate and overtake spin-generated lift. **TLDR**: The frisbee is an airfoil, that's why it can fly. The frisbee can turn because of its spin and its pitch angle.

Why do dogs drink out of the toilet, even though you give them fresh water?
|
As far as the dog's concerned, a source of water is a source of water. All he'll care about is that there's always water there, it's clean and at a convenient head height for drinking. Dogs are also creatures of habit and will keep going back to the same places for food and water just because that's what they're used to doing. If a dog's drinking out of the toilet, encourage him to drink from his own bowl by making sure that his bowl is always kept full of fresh water, that it contains enough water for him, that the bowl is always accessible and that it is always in the same place . Also, reinforce good behaviour by giving him treats for drinking from his own bowl.

What's preventing us from completely abandoning paper money going 100% cards or credits like in Science fiction?
|
Because not everyone is on a card and we would need a system that gives away free banking for everyone to be on a card and then we would need a free system to allowing people to trade between each other. Other wise there would be a lot of people and children who would have no way of having money and would make life harder to force people to have a bank.Because it doesn't make sense to make every transaction rely on both power and internet access. If the power goes out, no one can buy anything short of reverting back to the barter system. People don't want a record of every transaction they make. Any number of legal and illegal reasons apply here. Forces everyone to be part of a bank, anyone not literally cant buy anything. Some people just prefer buying things with cash. My card is purely a way to buy things online and pull money out of an ATM. When I am shopping I prefer to pay with cash as I know tangibly how much I am spending, not abstractly that a number with my name on it is being reduced in a bank. Makes it easier to not make impulse buys.

There are, for example, 50 clouds with rain in them at the sky. What makes them all release the rain exactly at the same time?
|
Clouds are so large that generally one cloud covers the immediate vicinity around you. So it appears that rain starts and stops simultaneously in all directions from the perspective of a person on the ground. But if you look at a rainstorm from an airplane, you can often see pockets of rain and non-rain across a fairly small area. It just isn't apparent from ground level. [This picture] is a good example. A person in the center of this storm won't notice significant differences in their immediate surroundings but from an external vantage point the rate of rain varies considerably.

On the back of my dove deodorant, it says to ask a doctor before use if I have kidney disease. How is deodorant correlated with kidney disease??
|
Deoderants and Antiperspirants contain aluminium. Aluminium is abosrbed by the skin and enters the blood, in healthy people, the level of aluminium found in Antiperspirants is safe as it is rapidly removed from your body via the kidneys in urine. But in people who have kidney problems, aluminium can accumulate in the blood and cause toxic effects .IIRC, it's a concern in antiperspirants, not as much deodorants.

Currently it's at about half a percent of the population, which is not exactly hugely common. What you might be seeing is higher public awareness in N America, but it's also possible that you're simply a victim of confirmation bias.

How does HD Radio work, and what makes it clearer than non-HD FM radio?
|
HD radio uses the same type of radio waves as normal radio but the information is digital instead of analog. Analog audio can get warped and distorted as it travels over the air due to interference. Digital audio doesn't have the same problems. A digital receiver only has to tell if the signal is a 1 or a 0 at any moment. Even if there is some radio noise it's still easy for the receiver to tell the difference between a 1 or a 0. With analog, some radio noise can make it hard for the receiver to re-create the audio signal.Instead of radio stations broadcasting an analog signal, they broadcast a digital one. There are some benefits and some drawbacks. One benefit is no more static, it's a "clean" signal. Another benefit is more radio stations, every station can now have 2-3 sub-stations, that can play even totally different genres. Now, onto the main thing, quality. The quality difference is dependent on the station. I believe a single HD Radio station can only broadcast a max of 150Kbps per main/sub-station. Also, there are power usage demands, which usually means that a station with sub-stations will likely be of lower quality, likely 120Kbps. However, that's because they still carry the normal FM signal, if a station drops the FM, than the pure digital signal is 300Kbps per main/sub-station. In regards to comparison with FM quality, 96Kbps-150Kbps is around what most FM stations sound like, so actual quality won't be wildly improved in terms of compression. However, FM does have the capability of producing sound better than 320Kbps MP3, but that is very rarely the case nowadays, some stations did sound very good > 10 years ago. So, as traditional FM becomes ~~fazed~~ phased out , HD Radio will defintetly sound better than FM.

Why are planets spherical, is it possible for planets to be Halo or flat edged?
|
The reason planets appear spherical is because gravity compresses the planet into a shape that most evenly distributes the gravitational force among the planet's mass.Planets are too big to be too far away from spherical - something sticking out too far will get pulled down by gravity over time. A Halo with the mass of a planet would collapse immediately; no known material is strong enough to support such an object.Planets are usually ellipsoids because it's much more stable than other shapes, but it is possible to form a toroidal planet. [This article] has a very nice analysis.

If you arrive in a country with some sort of incorrect visa, do they just send you back home?
|
Well, they will detain you in some holding area in the checkpoint, while they try to ascertain your identity - whether it's a genuine mix-up or error, or if you are someone more sinister - like a drug mule, terrorist, or a refugee who has no actual business in this country you are in. The immigration officials may ask you some questions, and maybe run some checks with your embassy and make some calls. If it's a harmless error, your visa gets corrected and approved, and then you get to pass on. If it requires more time, you might just have to be sleeping in the airport or train station for a few days while the things clear up. If ultimately they are dissatisfied and refuse to grant you the visa, well, you are plainly treated as an illegal immigrant and arranged for deportation/jail etc. . It sounds harsh, but well, you gotta understand that legally on paper you are no different from the other "wetbacks" and "boat people" and "border crossers" and what-not they are getting. Moral of the story: Don't fuck up your visa. It's as bad as crossing borders without getting your passports checked and so on. Basically, you are seen as just going into another country illegally. Period.The trick here is that it's the carrier's responsibility to remove you in these circumstances. If an airline allows you to fly in to some country and you are refused entry for lack of correct paperwork, the airline is required to take you away again. This is why they will be keen to check your documents at departure. The immigration officials don't have to worry about this cost.

Why do your ears and nose slowly and continuously grow throughout your life?
|
Because while bone growth stops in early adulthood, cartilage growth doesn't. Your ears and nose are mostly cartilaginous, so they continue to grow as you age. In addition, aging skin loses elasticity and underlying fat pads, making it sag more and the cartilage more prominent.

Why does medical research need so much of donated money when pharmaceutical companies are super rich and can afford to do the research themselves?
|
Pharmaceutical companies make drugs. They do not invent new surgical techniques, new equipment or new courses of treatment. Even in situations where the solution turns out to be different drugs, the reason pharmaceutical companies are super-rich in the first place is that they spend their money on those avenues best suited for a high return. Erectile dysfunction drugs are high return. Curing obscure forms of cancer is notBecause "big pharma" isn't one monolithic block, and even if it were, priorities are a thing. Companies exist to make money, so they're going to go for the easiest, biggest payback they can find. Medical research looking for donations is investigating things that don't fall in that "easy and will make us rich" bracketBecause academic and industrial research are looking at very different things. A lot of academic research is "basic science." It's focused on figuring out how life works and what is going wrong in diseases. It's absolutely critical to modern drug development, but in and of itself, unlikely to generate new treatments or valuable patents. Thus, academic research needs to seek funding from the government or private donors, in exchange for doing research for the benefit of humanity. Industry research is focused more on "translational science." Industry takes the basic science done by academia and translates it into treatments. This process, including FDA trials, can be enormously expensive, and is not something academia can to do. In exchange for taking these risks, industry can make substantial amounts of money.

the evolutionary reasoning/theory behind menopause
|
If we look at life as a game, we 'win' when we manage to pass on our genes to the next generation. The more we manage to do this, the higher our top score becomes. But, there is no use in passing on your genes if your children will die before they can reproduce. Especially for a species like humanity, where we have taken a quality over quantity approach to reproducing . So maybe it is better to say that you 'win' life when you have kids that have kids. Now as a woman gets older, her body deteriorates, including her eggs, meaning that kids that you have at an older age are less likely to survive to adulthood and be able to pass on their genes than kids you have at a young age. It still takes a lot of resources to create those children though. In a way you could see it as dumping resources into a bottomless pit that you get nothing out of. Lot of effort, but it doesn't work towards winning the game of life anymore. So what a woman's body does, it shuts down the factory. It says, we are not going to put our effort into shovelling resources down a bottomless pit anymore without any pay off. Instead, we are going to put out efforts in making sure the kids we already have are more likely to have children so our genes can continue on. That is what the grandmother theory is: it is the idea that at some point in a woman's life, there is more evolutionary pay off to supporting her already existing kids over creating new kids that won't live long enough to have kids of their own.

How were the transatlantic network cables put in place?
|
With a really big cable laying ship. There's no need for weighing them down. The cables are quite heavy by themselves. If a cable breaks a specialty cable laying an maintenance ship goes out, finds the break, brings up the cable, and repairs it or splices in a new cable section.[Modern Marvels] had a really good episode about this!They lay them down by gradually unspooling them from the back of a specially designed ship. They sink to the ocean floor and stay there forever, unless a ship comes by dragging a hook to pull the cable back up for repair and then puts it down again. In shallower water, rather than just dropping the cable, they drag a plow behind the ship that makes a trench and drops the cable into it, for protection.

I am blind in one eye. Can you explain what 3D movies look like?
|
In a person with normal sight, your brain can work out how far away something is because your two eyes see a different picture due to being a few inches apart. If you are blind in one eye, I 'd imagine that if you move your head from side to side, you 'd get a similar idea of how far away something is, because your brain works it out from how the picture changes as your head moves. When you watch a normal movie, you don't get this sense of distance, because both eyes see the same. Even if you move your head, both eyes see the same as each other. In a 3D movie, each eye sees a different picture, so your brain can see distance - but only if you have sight in both eyes. But if you move your head, the picture doesn't change - your left eye sees the same picture, and your right eye sees the same picture. So, if you're blind in one eye, you *won't* get a sense of distance by moving your head. But what a person with normal sight will see is similar to what you see when you move your head around outside the movie theatre. As for wearing 3D glasses outside the movie theatre, they're like not-very-dark sunglasses. They work by filtering light depending on its polarisation, which is perhaps a subject for another thread - but the short version is that light waves normally "wave" in all directions. The glasses filter out all the waves except those in a certain direction - but what you end up seeing is exactly the same as normal only a bit dimmer.

Last night I had a deep logical conversation with a character in my dream. How is this possible?
|
Why would you presume it to be not possible? You are, presumably, capable of logic, and the 'you' and 'character' in your dream are manifested by you, so they are presumably capable of logic as well. The only means to measure the grasp of the logic is your own experience, so even if you have a poor grasp of logic, your poor grasp of logic doesn't necessarily permit you to evaluate the logic from the dream as being poor. And if you have a good grasp of logic, then there doesn't seem to be any particular reason why characters made up by you wouldn't also.

|
You can, but generally you are breaking a law. Or at least an ordinance. Plus, your patch *sucks* and will form another pothole shortly. DIY asphalt patching simply isn't capable of standing up to the sort of abuse that road get -- unless the person doing it themselves is a professional with professional-grade equipment. The fastest way of getting it patched is to call the city/county and let them know there's a pothole there. If it's not reported, they'll never know it needs to be fixed.Sure .But you will be accepting responsibility for any damage it causes in the future.

Why is it when counting numbers teen comes after the number but every other number after that the number comes at the end ?
|
The suffix [-teen] originally meant "ten more than". So thirteen is 'ten more than three\', fourteen is 'ten more than four\', and so onGermans have it easiest. 15 fünfzehn means literally five-ten 25 fünf und zwanzig five-and-twenty. fünf und neunten is five and nine tens or 95 etc but from 30 to 90 is literally 3 tens, 4 tens etc dreiten, fierten, funften, sexten

Why do so many African Americans have Welsh surnames?
|
That former slaves took on their previous owners\' surnames is a widespread myth: the one thing they didn't often do was to assume the names of their former oppressors. They usually named themselves after other famous Americans, especially those they regarded as heroes of the anti-slavery movement: thus African Americans called "Brown" are named not after the slave-owner Jerrett Brown, but the abolitionist John Brown. I don't know that Welsh surnames are particularly prevalent among black Americans. It's very difficult to judge, though, because the Welsh didn't have surnames until they were forced to adopt them by the English. As a result, the most common Welsh surname, Jones, is actually English in origin, and picked by many families simply because it was already a common surname in England. Looking at [a list of the most common surnames among black Americans], the first one that is undoubtedly Welsh in origin is Davis . That's an interesting one because the one Davis most closely connected with slavery is Jefferson Davis, who was a fierce advocate of slavery, so unless I'm missing something that does break the usual pattern. You have to go all the way down to the 38th most common, Evans, to find the next unambiguously Welsh name. Names like "Williams" and "Thomas" are *common* in Wales, but in origin they are English -- and in any case mean nothing more than "son of William" and "son of Thomas", so could simply have been chosen for that reason . "Davis", of course, can also mean simply "son of David".

Net Vertical Impulse with a drop jump AND a counter movement jump
|
When the athlete drops 0.3m, he will land with a velocity. When the athlete jumps 0.45m, he has an initial velocity. We seek the change in velocity first. We know that position = velocity × time. We know that position = acceleration × time × time An athlete falling 0.3m will fall for: 0.3 = 1/2 × 9.8 × time × time 0.6 = 9.8 × time × time 0.6/g = time × time Sqrt = time During which time, your athlete will accelerate: 9.8 × time or 9.8 × Sqrt That is how fast the athlete hits the ground. When the athlete jumps, he will leave the ground with a velocity sufficient to hit 0.45m. That is to say: Upward velocity - gravity's acceleration maxes at 0.45m Gravity's acceleration will again be 1/2 × a × t × t Solving for t gives us sqrt for the duration of the upward part of the jump, at which point, the athlete will have accelerated 9.8 × , giving you your starting velocity for the jump. So, the total change in velocity from down to up is: gravity × sqrt + gravity × sqrt Or gravity × +sqrt) Reduce as you see fit. Figure out the mass of your athlete, and solve your momentum.

The economics of C.H. Douglas' theory of Social Credit
|
I 've always struggled to understand social credit theory as well. Here in Alberta, Canada the social credit party formed the government for 34 years straight. They were a highly socially conservative christian party which left much of the social credit reforms unaddressed. For a time they issued "prosperity credits". These were essentially currency that decreased in value each week. They were designed to keep people from hoarding money during the great depression. They were extremely impractical at the time though and were barely used. The Socreds also tried to reform banking in the province, but I 've never read how. It ultimately failed because a province doesn't have enough authority over banking practices to enact these changes. Ultimately, from my interpretation, think of socialism as government programs funded by taxes, and social credit as laws that see workers paid a a minimum wage that they can live and grow with. It's goal wasn't financial equality so much as it was a guaranteed minimum standard from which people can flourish. I could be wrong though, my understanding is limited to the historical sentiments of one case study. Probably not the best perpective. Hope it lends a bit of insight at least, I'm probably going to look up more now.

how does free shipping and handling work?
|
There's still shipping and handling costs that are part of getting the product to your doorstop, but the company that's selling them pays for them and buries their costs in your product price. Here's the four cases for a $10-price product that costs the company $7 to make, with an extra $2 of cost for paying the delivery service and packaging up your product for delivery: * You pay a separate shipping and handling charge. The bill shows one $10 line for product cost, and a separate $2 line for shipping and handling fees. Profit = $3. * You pay no shipping and handling charges ever. The company's bill simply shows $12 on one line because they set the price at a level that covers shipping and handling as part of their normal practice. Profit = $3. * They have a "buy enough and you get free shipping and handling". So you buy $100 worth of stuff to get the free shipping, which is more than you intended. The profit off the extra stuff you bought but otherwise wouldn't have bought covers the $2 cost to deliver that one item, and more. Profit = $1, but they sell a LOT more stuff. * They have a "free shipping" week. Again, a lot more sales are going to come in that week from people taking advantage, so the $2 of extra cost is just absorbed into all of the extra revenue that the sale creates. Profit = $1, but they sell a LOT more stuff.

Why doesn't AAA kill all their useless perks and just make membership cheaper?
|
Those discount deals don't cost AAA anything. In fact, they probably get paid by the partner companies: it's marketing for the companies. AAA is essentially selling their customer list, and advertising directly to them. And of course, AAA gets a benefit as well, since their members feel they are getting something more for their membership fee.

When astronauts are in space and they use trusters what are they trusting against to move forward?
|
Thrusters don't work by thrusting "against" anything. They work based on the conservation of momentum. When you throw something in one direction, what remains has to move in the opposite direction for the momentum of the entire system to remain the same. Imagine standing on a skating rink wearing ice skates and holding a bowling ball. Now throw the ball forward. That will cause you to slide backwards. That's not caused by the bowling ball pushing against anything; it's cause by the fact that, when you push against the bowling ball, you're pushing yourself backward just as much as you're pushing the bowling ball forward . Rockets do the same thing, expect instead of one massive bowling ball being pushed slowly, it's trillions of low-mass molecules of burned fuel being pushed quicklyThey are not thrusting against anything to move forward. The force of the gases shooting out moves the vehicle in the opposite direction.

why does an analog clock's second hand continue to move, but stay in the same position, when the batteries are low?
|
It's not a feature, it's that the second hand requires a certain amount of force to be moved. If the motor running the clockwork doesn't have enough power to move the second hand all the way, it just keeps chugging ticking half seconds and falling back to its initial spot. The reason it doesn't stop entirely is because it would cost more money to put in a device that figures out when the second hand isn't moving enough and stop the mechanism. It's not that they have enough juice to move the second hand, they don't. Just because you can lift 50lbs ten times doesn't mean you can lift 500lbs once.

Why is there a lot of ruckus over how America is moving from an industrial economy to a service economy?
|
Industrial jobs, due to their more skilled nature, are more likely to have higher wages and worker's rights, where as in a service oriented economy, workers are unskilled and easily replaced, allowing them to be paid as little as possible with fewer rights. Since workers in an industrial economy have more money and rights, they tend to have a better standard of living.

Why are so many video/computer games not available in Australia?
|
Cost. Not just physical costs like shipping, which can be mitigated with digital distribution, but international trade/licensing agreements come into play. For many non AAA titles, it may just not be financially viable to distribute there.

What is the difference between a nightmare, a night terror and sleep paralysis?
|
Nightmare = a scary dream you have while asleep. Night terror = a scary feeling you have that remains equally terrifying even after you wake up. Sleep paralysis = a side effect of being asleep , in which your body doesn't respond to signals from your brain telling it to move.

Why is the human tongue so strong? Evolutionarily, how did it develop that way?
|
The tongue is something that often gets taken for granted. When you think about it, it is incredibly important for eating. It's main job is to move food around in your mouth to the optimal teeth for chewing. Moving a piece of food from one side of your mouth to the other is not in itself very difficult, but when you are eating, your tongue is constantly doing this over and over. It takes a good amount of muscle to be able to do this constantly for long periods of time, so your tongue needs to be strong. In terms of evolution, it can be put pretty simply: Ability to get food is a very strong evolutionary force. They stronger your tongue, the more, different types of food you can eat, which leads to more caloric intake, which gives you a small edge over others with weaker tongues. Over millions of years, evolution will select for individuals with stronger tongues.

Where did the idea of people becoming angels when we die come from, considering that bibically angels are another species altogether?
|
Its just misunderstanding. Because the origins of the angels is rarely discussed. Honestly most people never talk about those early parts of the bible that explain the angels place in things because its kind of embarrassing.. Like how angels would rape human women because seeing their hair made them super horny. It led to a hybrid race of giants! Yeah That's where the whole women covering the hair thing comes from I think this causes some discomfort in discussing them in any detail so people just make up their own shit about them. Basically angels exist to serve. They are tools for God like a screwdriver would be for a person. They rank lower in the heavenly hierarchy than humans so becoming an angel would actually be a step down for a human.

Why does hot water set stains in cloth? Why does cold water help get them out?
|
When cloth fibers get hot they expand, thus allowing the contents of the stain to get deeper into the cloth. The the cloth fibers are cold they constrict, thus pushing the stain out of the fibers.

How is all of our poop disposed of when it is flushed down the toilet?
|
When I was about 16 I worked on a private school campus where they had their own little waste treatment place. There was a swimming pool sized pool that had three or four sections. The first section had the raw sewage water in it and was constantly churning. There were plastic things that separated the sections and were just high enough to let some of the water over into the next section. Each section was progressively cleaner than the previous one. We would spray water on the sides to prevent buildup and my boss would measure out chemicals like lime to break down the sewage. They also had screens on poles that we would use to pull out bits that didn't break up. By the time it was in the last section, the water would be clear. I realize this isn't a definitive answer but it should give you a general idea of how it works on a small scale. On a side note, One of my friends had just started working on the maintenance team with me and we were going to go help out at the sewer place. I convinced him that he would have to put a suit on and actually get into the pools to help clean them.
