Why did video game developers stop using footage of real actors? Wouldn't that be the most realistic option for say, a FPS?
It'd be uncanny valley. [Beowulf] in 2007 was pretty much one-of-a-kind because it looked so close to realistic, but it was just that much off. Your brain is really good at picking up on the subtle failures of lighting and colouration that CGI can make, so you either spend way, way too much time and energy on CGIing everything perfectly - and even then many people will still get a sense of it being fake - or you just roll with a less realistic art style. When it's [obviously fake ]people don't generally find it [off-putting]. LA Noire did a pretty good job on getting real actors to not be too uncanny valley, but some people still found it really odd and even if everyone thought it was perfect it was a really difficult process to get the full human face in the game properly.Search YouTube for gameplay of "Mad Dog McCree" and ask yourself if it looks realistic. Also, using rendering gives great amount of flexibility. You can edit and change your scenes in every way, while footage taken with actors is more or less set in stone - unless you are willing to redo it and throw existing footage away. Not to mention that jumping between movie cut scenes and 3d missions would be tiring for viewer and provide uncanny valley effect. Visual consistency is much more important than "realism".
The "Paris Agreement" on climate change
> What is this? A agreement to collectively take action against human-caused climate change and reduce the negative impacts of global warming and climate change in future years. > What countries participated? Nearly every country, 196 to be exact. The largest agreement ever of its kind. > What agreements were made? A commitment to limit global temperature rise well below 2°C , with countries also agreeing to try and limit the rise to 1.5°C. For reference, it is thought that any rise in temperature beyond 2°C may have catastrophic climate effects and very serious consequences for many countries down the road. The agreement also involves helping poorer / less developed nations combat climate change by providing these countries 100 Billion dollars of funding each year to help with the development of sustainable and renewable energy and greener industrial practices in these regions. As part of the agreement, countries will also have to be more transparent with their greenhouse gas reduction targets and their performance . The ideal is to be carbon-neutral by 2050 but unless we dramatically reduce our reliance on fossil fuels, this may be a tough target to reach. > How will this effect Climate Change? Hopefully it will prevent catastrophic climate disasters in the future , and perhaps even have a modest impact on reducing extreme climate/weather phenomena in the short-term as well.The Paris agreement was a unanimous agreement that countries would limit world temperature increases to less than 2C above per-industrial levels. The agreement stats that all countries must contribute to this reduction not just already development countries. Nothing has actually been establish as to *how* this will occur. Countries have until 2018 to submit their plan for carbon reduction. While this is a good first step, the reality is that most of these countries "agreed" to the treaties, but they will still have to get them approved in their own country. For example in the US the Senate will actually have to take a vote to officially agree to anything.A bunch of countries agreed to try to keep temperature rises under 2C. However, there's absolutely nothing binding other than setting a voluntary target and then reporting on it.
How does currency work in the world markets in terms of inflation, exchange rates, stocks, etc.?
If a bunch of people in foreign countries suddenly want to buy American goods, they're going to need dollars to do that. Same thing works with stocks. Ford doesn't take the Japanese guy's yen to pay for the stock, they only take dollars. So, you have a bunch of people who want to get dollars. Just like anything else in economics, currency exchange rates rely on the principle of supply and demand. If the demand for American dollars rises, then the 'price' of those dollars also increases and the dollar becomes *more* valuable relative to other currencies. Hope this helps!
How google maps work?
Not quite sure what it is you are after. If you are wondering though how it gets stuff like traffic info, then look into the app called Waze.
Why were dinosaurs so much bigger then pretty much every animal around today
The truth is we don't really know, some of the more common theories are. 1. The world was different then, compared to today. Oxygen content of the air back then was much higher. 2. The planet was warmer, with lots of plants for them to eat, and less competition for the food. 3. A large cold blooded creature has sufficient mass to maintain heat, even when the weather is cooler. 4. Being large was a type of self-defense, too big to kill and eat.
When there is a breaking news story (or important event) how does a news channel get away with having no commercial break? Do they loose revenue?
Doing lots of coverage on an important event will make viewers like that news show more, resulting in more returning viewers when there is less exciting news on and ads run normally.
How do currencies have different values/worth?
When you exchange currency from one country's to another's, the ones making that transaction, usually banks, are left with that currency you exchanged. For example if you went to Germany from the U.S. and exchanged your US dollars for Euros, that German bank now has some US dollars. For that to be a worthwhile transaction for them, they would need to be able to exchange those US dollars for goods or services that are at least equal in worth to the amount of Euros they gave you in exchange. Now let's pretend there's only one product in existence: Nutella. But there are no cocoa or hazelnut trees anywhere in the U.S., they're all in Germany. That means if you were to buy Nutella in the U.S., it's either been manufactured in Germany and imported to the U.S., or the raw materials were imported and it was manufactured in the U.S. Either way, the costs of getting that Nutella onto shelves in the U.S. was higher than in Germany, so Nutella is going to cost more in the U.S. Now going back to that bank you exchanged money with, they're not going to exchange those US Dollars for an equal value of Euros, because they only exchange those US Dollars for Nutella from US vendors, which are more expensive. Of course, in reality it's a much more complex web of resources, raw materials, factories, and countries, but that's the general idea.
Since silverback gorillas have such humongous guts, how come they don't get diabetes, heart disease, and other obesity related health problems?
A thing to consider is time. A gorilla's lifespan is normally between 35 and 40 years. And health problem with obesity in humans develops over time but gorillas develops faster and humans usually don get obese at a young age. The diet of a gorilla is low in sugar and fats and is likely similar to what would be recommended for diabetics. And you cant necessary draw conclusions form humans to animals. Bowhead whale have more fat content then a human but can live for over 200 years. And then there is the problem in the question. How do you know that those are not the common causes of death in gorillas? The final question that should have been the first one I looked at. Do gorillas have fat belly?It looks like the answer is NO. The belly is large because the have larger intestines since they eat more plant fibrer then we do and can ferment it. Compare the stomach of a cow and and a dog to notice that plant eaters need larger stomach. _URL_0_", 'The food they eat does not contain the bad fats and sugars that we eat. It might look like a "fat gut" it is pure muscle to support there upper body.
Why is my internet connection speed much faster on my laptop than on my iPad from the same place in my house?
Because your laptop is probably euipped with an better wireless card, that will give you further range and faster speeds than a simple Ipad.It's just because your laptop itself is faster. The internet is like you and a professional chef cooking. It takes the same amount of time to drive to the store to get the ingredients but when home putting it all together he can chop slice dice and mix faster than you.
How do some noises make your teeth feel weird?
The only thing I can think of is [resonance frequencies]. Mythbusters did an episode on the myth that it was possible to break glass with the human voice, in which they studied how each object has a specific resonance frequency. Any time an object is affected by a sound or force at that frequency, it oscillates with the sound/force. You may notice that if you sing in your shower the shower starts vibrating. Same thing happens with water bottles. My theory on this is that when teeth are exposed to their resonance frequency, it causes them to feel weird. Please feel free to refute this.I can't stand the thought of my teeth scraping a Popsicle stick..
Why do Modern Art exhibitions showcase pieces that lack technical skill?
Technical skill is not the sole criterion for judging the value of a piece of art. Look at the music world, bands like the Sex Pistols and the Ramones are considered greats, and you could play their songs with minimal training.
I've seen this more and more, but why do people put their cell phones on speaker and then hold the phone an inch from their mouth?
I don't know about men that do this, but women do it so you don't end up with a phone covered in make-up and hair products. Also, depending of your earrings, you can get a clanking sound when your earrings hit the phone. Source: my wife.
Why do many businesses, especially those with long term aspirations lease vs buy their buildings?
Lease payments are deductible business expenses. Leasing property or equipment reduces a company's taxable income dollar-for-dollar. A building owned by the company is an asset. Depreciation reduces taxable income, as well as does interest on loans taken to acquire business assets, but in general leasing is the better option for tax purposes. Of course, there is less risk involved with leasing than with ownership. Ask anyone who has moved to a new house while being unable to sell the old one.
How astronauts digest food in space
Astronauts eat three meals a day , just as they do on Earth. Meals are organized by the order in which astronauts are going to eat them, and stored in locker trays held by a net so they won't float away. When mealtime rolls around, astronauts go into the galley area in the shuttle's middeck. There they add water to freeze-dried foods and dehydrated drinks from a rehydration station that dispenses both hot and cold water. They heat foods in a forced-air convection oven that's kept between 160 and 170 degrees Fahrenheit. It takes about 20 to 30 minutes to rehydrate and heat an average meal. Each shuttle packs enough food to last the length of the mission, and then some. A Safe Haven food system provides every astronaut with an extra three weeks' worth of food -- 2,000 extra calories a day -- just in case the crew encounters an emergency. These foods are typically dehydrated for a longer shelf life.Astronauts may have plenty of food to eat, but being in space can put a damper on their appetites. Without gravity, food aromas waft away before they make it to the nose. When you can't smell food very well, you can't really taste it, either. And because fluids tend to rise to the top half of astronauts' bodies, the crew members usually have perpetually stuffy noses. Salt, pepper, ketchup, mustard and mayonnaise are available to enhance the flavor of the food, but even then, the condiments are different from their terrestrial counterparts -- salt and pepper have to be suspended in liquid so the particles don't float away.Food digestion and movement of food and waste through the digestive tract does not require or rely on gravity. Instead, the muscles of your digestive tract contract and squeeze the food through your digestive tract through what is called peristaltic action.
Why do Men Go bald on the top and sides of their heads but not in the "beard/mustache" areas?
It has to do with the follicles on that part of the head. Men with male pattern baldness have follicles on the tops of their heads which react to a specific hormone that causes them to recede and eventually stop growing hair .
Photo analysis/Face detection algorithms (snapchat face filters)
I don't really have much experience in this field. But as far as I know it goes something like this: First of all the algorithm is trained on low-resolution images of faces from different angles. Several filters are applied to the training images to enhance facial features . Here's an example: _URL_1_ Now for the image you want to detect faces on: 1. Apply the same filters and make the image low resolution to save computational power. You just need the features to be enhanced. 2. Compare pixel data to training data. 3. If the training-data has facial regions defined you can extract and pinpoint them. 4. You should now have a box of where the head region is, making it easy to add a mask. For more look at OpenCV.
How was Thomas Young's light wave theory proven?
What was Young's experiment to prove the wave nature of light? The double slit experiment. If you don't already know what it is, two slits were made that were kept a very tiny distance from eachother, and using a single source, or two sources in phase, light was shone through both these slits . The observation was that you'd get bright and dark fringes. What did this mean? & nbsp; This meant that light can interact with eachother. There are two types of interactions, known as constructive interference and destructive interference. Constructive interference is basically the bright spot, where the light from both the slits add up and you get a bright fringe. Destructive interference is basically the dark fringe you get, where both the light waves from the slits cancel each other out. This proved the wave nature of light .
Why do rocket engines look so complicated if they're just an opening for a controlled explosion?
Because it's a massive explosion and everything massive is complicated to control. You need to be able to keep watch on and influence massive ammounts of fuel flow. You have to be able to control the direction somewhat . You have to take care of a massive cooling system too. And probably a lot of other things I can't think of from the top of my head.
How do chocolates (during the late 1800s) survive in temperate climates like in the Philippines without refrigeration?
[Ice box] It’s like a cabinet that has a huge area for one massive fucking ice block and then the other side has the storage area and below was water collection', "Now, for something that needs middling storage temperatures, like a modern chocolate bar, a cellar will likely keep it intact for some time. Chocolate of that nature will keep for some time at 30c, thought it isnt as firm. In the 19th century however, 'chocolate', was normally used to refer to what we would today call 'Hot Chocolate', a drink from processed Cocoa powder, which doesn't melt, not having read the book though, I can't say if that is what was meant.
Why does the government provide “stimulus” to banks rather than just larger returns to low to middle income earners?
they did do that. _URL_0_*almost* everyone got $600 cold hard cash. Unfortunately this money was quickly blown, often on imported goods that did nothing to support the US economy. Quantitative easing was a more direct route to not just subsidize spending, but to facilitate liquidity for the market to operate naturally. There was also cash for clunkers, which IMO was a fairly ingenious plan to support the auto industry while reducing pollution. Unfortunately it turned out to be insufficient.The most recent Freakonomics podcast was an interview with Ben Bernanke which explains this from his view and makes fun of him, just a little bit. I'd link but I'm on mobile.
Why can I adore the smell of a certain food, but dislike the taste? Is there no connection between how a meal smells and tastes?
Aromas are much more complex than taste. But what we perceive as flavor is the combination of the two. Our brain smells coffee and appreciates the complex hydrocarbons from the roasted beans. Our brain tastes hot water.
How were Double Role movies shot back in the day when their was no CGI
This is my first time posting here, and I don't know if you can post links, but I just saw a great video by "Crash Course" explaining how early cameras created illusions. It should answer your question. _URL_0_
How do we inherently know what notes to whistle?
There's isn't any "real" notes. Even the idea that everyone "should whistle the same notes" is only around 200 years old. Before that, every place had different notes they played on. The frequency "C" of today is absolutely arbitrary. Which means we don't need any prior information to whistle, everyone knows to just go up-down-up-down-up-up in frequency . It also means the Mozart you hear today, isn't the way Mozart wrote it Essentially there aren't any notes , there's just an up-down-up-down sequence. People with perfect pitch just happen to do their "up and downs" at the already arbitrarily agreed upon frequencies we have today . *this doesn't necessarily make them a good singer --just better at singing alongMusical pitches all have a specific *interval* between it and the next pitch in any given melody. Those intervals are called steps and in western music you have whole and half steps. So if you are whistling a "C" then you can blow an "F" by adding three steps. Or an E-Flat with 2.5 steps. You may not know the pitch but you can judge the interval well enough from memory. Same if you were just picking out the melody with an instrumentIt is not any different from humming notes. You dont inherently know how tight you have to squeeze your vocal folds to sing or hum notes.You learn it just like whistling. Same as any other instrument.We don't initially know; this is something we learn from years of practice making sounds with our mouths.
Why don't we put solar panels on wind turbines?
Some panels are placed on the supporting structures but placing them on curved surfaces isn't that easy. Placing them on the blades isn't practical for a whole host of reasons.
Why are cats so fascinated by boxes?
The safest place in nature is a hole or cave where you're protected on 5 sides and only exposed on one. Evolution favors safe behavior like this, so it has become instinct. An open box is the modern equivalent-only open on one side, danger can only come from one direction, so they feel safe. It's also the reason cats will "knead" the ground and walk in circles before laying down-they're checking for anything pointy that might hurt them. Not so important for a box in the living room, but a good thing to do when laying in a hole that might have a thorn or pointy rock at the bottom out in the wild.From what I've read, they feel safer. I'm sure there is more to it but that is the basic reason", 'They are, essentially, den animals. Feral cats will live in dens.
Why do fly’s rub their hands together?
The fly's mouth ) extends straight down, so as a result flies usually stand ON the food they eat. And they like various liquids , which they suck up . So they rub their legs to clean them.
Why do some languages adopt new words for recently invented items?
Quite often a word will be used that literally describes the object, or what the object does, this could be for convenience as sometimes the inventing country's word might be difficult to pronounce. In a few countries it is common to adopt the inventing country's word though. In fact inventing a new word might be for different reasons: Interestingly South Korea will use the English word for Western inventions, while North Korea refuse to and will invent their own word.
Why is the Linux OS so popular to use in science and research equipment?
It's really flexible, so it can be used more efficiently for highly specialized tasks. Also, a lot of research software is written for it.
Why my pubic hair grows so much faster than my facial hair.
speak for yourself, its neck and neck over herePubic hair is the same kind of hair you have in your armpits and to a lesser degree your eye brow/lash hair, your facial hair is the same kind as your normal head hair, so they grow in different ways and to different lengths.
how do we “forget” things? And where do those memories go?
Memories are formed by connections between cells called neurons in your brain. Each memory is a unique *wiring* up of neurons. When electrical nerve signals pass through the wiring structure you remember the memory. Your brain has an amazing capacity but it is still finite in size and has to prioritise the information it chooses to store. As a result, it is constantly rewiring and changing connections between neurons as you learn new information and make new memories. This means that old memories or lesser-used knowledge gets vaguer as the wiring associated with these is restructured by the brain to accommodate new information. It will probably never be completely gone but will become much more difficult to recall or will possibly change as the wiring in your brain changes.
What is the difference between a Loner, an Introvert, and an Antisocial person?
I think you might be confusing the terms asocial and antisocial. If you are antisocial you are being unkind or abusive towards other people. If you are shy you are being asocial.I'm would say a loner is happy in there own company but can handle groups fine.An introvert does not necessarily want to be alone but does not cope well in unfamiliar or large group situations.An antisocial person does not handle social situations well and acts out accordingly. Not an expert, just my opinion
Would a modern version of Spartan way be more effective, in theory, than traditional military effectiveness?
> easily the most effective fighting force in Greece Per unit, yes. As a whole, I highly doubt it. Spartans *were* badass as fuck. But there weren't very many of them. They only won the battle at Thermopylae because they had a terrain advantage. There's a reason they mass produce modern soldiers the way they do. A single badass never trumps 10 'good enough' men, because it only takes on bullet to stop him. The best fighting force is easy to train, equipped by the lowest bidder and utterly replaceable. Sad truth is that is how the military works. Because it's the most *efficient* way for it to work.
If conjoined twins share a stomach, do they both feel full or hungry at the same time?
It's hard to make general statement about conjoined twins because literally every case is different, but the feeling of hunger is regulated by hormones, most importantly Leptin and Ghrelin, which circulate in the blood. So if the conjoined twins share their circulatory system , then these hormones will always affect them at the same time. However, there might still be a different reaction in the brain to the hormones.
Why are there so many different species of animals, yet we as humans are all one species?
There have been many different species of "humans" that did coexist at times. This site has a list of some of our relatives that died out along the way, with approximate times of extinction so you can compare and see which ones lived alongside each other, if you like. _URL_0_ Exactly why our line is the only one left is up in the air, but most likely includes the same list of reasons other species die out - someone better comes along and wipes you out, you don't adapt to changing environmental conditions, etc. There's evidence that Neandethals didn't necessarily die off, but merged with homo sapiens at some point as their DNA can be found in modern Europeans and Asians .I don't understand the question. If you single out a specific species, there's only going to be one of it as well.
If the primary colors are Red, Yellow, and Blue, then why are pixels made to only show Red, Blue, and Green?
RYB are the subtractive color primaries, which works with paints and reflective surfaces where adding more tends to make things darker. RGB are the additive color primaries, used on screens and projections, working with light sources where adding more tends to make things brighterPrimary colors as RYB is mostly just for art, the scheme was created based on the way paint mixes. Unlike RGB which is the basic or primary color scheme as defined for physics and chemistry texts and is used for electronics. RGB is also known as "additive colors" adding RGB together will produce a white light which is the basic principal behind TVs and other monitors. To get more into it RYB is for paint mixing and the like and RGB is for light. Because when you mix RGB light, mixing darker colors will produce lighter colors . Where mixing paint darker colors give dark results . So when it comes to colors the medium you're working with will decide what base color scheme is usedThe difference is pigments are subtractive colors. Light is additive. Imagine this: mix together the primary colors of paint. You get a muddy brown. Mix together Red, Green, and Blue light bad boys.) You get white light. Pigment primary colors are actually Cyan, Magenta, and Yellow Since the pigment is absorbing many frequencies of light and only reflecting a certain few, we call it subtractive. White light is made of many colors, and this can be seen in a rainbow or a [prism]. Imagine you had a white sheet of paper with red text on it, and you only had a red light source. What would happen? The text would be invisible. Since the only color of light you have is red, only red can be reflected. If you add another color, then you will be able to see the red text, since the white paper will reflect both colors, while the red text will only reflect red.
Beveridge Model vs Single Payer system
The answer to your question is written in black and white in the links you provided. From the Beveridge Model section: > The term 'Scandinavian model' of health care systems has a few common features: largely public providers, limited private health coverage, and regionally-run, devolved systems with limited involvement from the central government.. Due to this third characteristic, they can also be argued to be single-payer only on a regional level, or to be multi-payer systems, as opposed to the nationally run health coverage found in Canada, Taiwan and South Korea.
Why do we have fiction stories (books, movies, games)?
Stories help us learn about the world and the values of our culture. Consider the movie *Twelve Years A Slave*. You could learn the details of slavery through a textbook and learn about the morality of slavery through moral treatises, but it won't have the same effect as watching a movie telling the story of a man who is enslaved. Stories can help us communicate things that we have trouble putting into words. It's a lot easier to tell stories about good people and bad people or people doing good and people doing bad than it is to work out a systematic morality that can guide how we should live.
Why does the barometric pressure drop when a storm is overhead?
From what I understand, the pressure is not low because the storm is overhead. The storm is overhead because the pressure is low. Take a ziplock bag and fill it a quarter of the way up, the lay it on its side. If you apply pressure, the water moves out of the way to where there is less pressure. When pressure is low, the moisture gets forced higher in the atmosphere. The higher it gets, the more condenses and starts falling back to earth. The swirling from the air and moisture moving up cause static electricity. Mix that all together and you've got a storm.
How can we sense someone behind us even if the person is dead quiet?
You sensed it either through smell, sight, touch, or hearing. You may not have been consciously aware of it, but that's what happened. There's also a good deal of confirmation bias because you remember all the times you turned around and someone was there, but don't remember the times you turned and nobody was around. Anyway, this gets asked a lot, so please search first.
Why are peanut allergies so often really serious?
Peanut allergens, since they are a food product, can come in direct contact with the internals of the body. The swelling they cause can cut off the ability to breathe. And let me tell you, suffocation is a very serious problem that can kill you quickly.Sampling bias. You don't hear about the people with mild nut allergies, since they don't make a big deal about them. I'm allergic to nuts, but if I eat them, all that happens is I throw up and feel like crap for a while. I can sit next to people eating nuts, and probably kiss someone who had just been eating nuts and not have any issues.
Why is Belgium a really powerful and influential country given the size as they are home of the EU headquarters?
It isn't it fact quite the opposite. It is such an irrelevant little country that it was *perfect* as the place for EU HQ. Putting it in Germany would have annoyed France and having it in Paris would have pissed off Germany and of course the UK would be pissed regardless . But Belgium well nobody can be offended by that choice.
Why do all deaf people speak with that specific tone in their voice?
They can't hear, so they can't hear the voice inflections that we all have. This means they have never learned how to properly use voice inflection. Instead they have just been instructed on how to properly form letters and words. This is difficult enough to teach someone who can't hear, and voice inflections aren't totally necessary, so they get dropped in favor of spending more time on the pronunciations.
; why is it that people snore when they are asleep, but don't have the same breathing pattern when awake?
When people lie on their back the soft tissue hangs farther toward the back of the throat because of gravity, partially or completely closing off the airway. When people breathe in, the negative pressure flaps this tissue and causes noise, which is snoring. When people are awake gravity doesn't pull the tissue in this direction so no noise is created.
What is the receipt of retired pay? "Would you be entitled to receive VA disability benefits but for the receipt of retired pay?"
> "Would you be entitled to receive VA disability benefits but for the receipt of retired pay?" In other words, would you be entitled to VA disability *if* you weren't receiving retirement benefits from a different source?
Want to check if your answer is appropriate for a 5 year old audience? Use this simple tool to measure grade level of your writing.
Thanks! Alternatively, you can calculate an actual grade level of readibility by using the [Flesch-Kincaid Grade Level formula]. I don't know any good calculators for this online, but I do know you can calculate it instantly by pasting the text into Microsoft Office, and then spellchecking. You will have to change your spellcheck settings and check the box that says something like "display readability information". I 've found that systems like Flesch-Kincaid have worked very accurately with papers I wrote in Jr. HighI put the word "elephant" in 56 times and received a SMOG level of 43.99 - in other words, more than twice as difficult as the IRS Code that requires a post-graduate degree to understandThis is definitely useful for determining when someone is using too many big words, but we should be careful to distinguish between *reading* ease and *understanding* ease. Five year olds can barely *read* at all, yet that's what this index is measuring. It's also [based] entirely on the number of 3+ syllable words per sentence—meaning that "elephant" would count as an advanced word, while "quark" would not. So, potentially helpful as a guideline, but far from infallible.
What happens in the engine if you put diesel in a petrol car?
If you have some petrol in your car and put diesel in it, it will start but smoke heavily through the exhaust. Damage will not be great to the engine though. However, if you fill in an empty tank of a petrol car with diesel fuel it will never start. If you've ever compared gasoline to diesel fuel, you know that they smell different. They also feel different -- diesel fuel is oily. Like oil, diesel fuel doesn't evaporate like gasoline does. Plus, diesel fuel is heavier. A gallon of diesel is about a pound heavier than a gallon of gasoline. There is the requested summary of what's happening in the engine: The fuel injectors in your engine would inject the diesel fuel into the engine's cylinders. The spark plugs would fire, but nothing would happen after that. Because the diesel fuel doesn't evaporate very well, the spark plugs would have nothing to ignite, and the engine would never start.Also, you would likely hydrolock the engine and have to wait for the diesel fuel to seep past your piston rings and into the oil sump before you could try again. Do this enough times and you can cause damage to the oil pump. Hydro lock enough times and I believe you can damage the crank and cams.
How is it possible that I copied a file without copy all of its content?
I would make another copy, and get the user to try to put more data into the file as they had done before - see if it shows up. My brain goes to PICNIC error first here. If your system said the file copied successfully, then it most likely did . It's extremely unlikely for a copy operation to keep a file in a readable format, but leave out some data.
Why does it hurt getting water up your nose when swimming, yet having a runny nose isn't the least bit uncomfortable.
First of all, if you think a runny nose "isn't the least bit uncomfortable," you 've not had a real runny nose! It can be *extremely* uncomfortable. Now, your nose is designed to let liquids drop out, not to take them back in. When you get water up your nose, it goes into all the nooks and crannies that nothing's supposed to go into, and where if something's flowing *out*, it'll just glide overClean water irritates the lining of the airways. It's not supposed to be there and that "skin" is not used to that kind of staff. There is not enough salt in it, and the acidity is wrong, and if it's a bath there is probably soap, right? Salty water, for example, fits the bill better and doesn't cause so much trouble.It's just the force that the water enters your nose. If you use a netti pot to clear your runny nose, it doesn't hurt to put water up your nose. It's uncomfortable sure, but not painful.
Why do dark-skinned or black people have their palms and soles paler than the rest of their body?
A layer of skin called the stratum lucidum is found in frequently used areas of the body, like your palms and the soles of your feet. The added protection of this extra layer means you don't need extra melanin in your palms or feet, so the skin is lighter. EDIT: To clarify. Melanin is what makes skin dark, and it protects the body from many things. Perhaps its most important job is to protect the body from harmful UV rays emitted by the sun. That is why people with darker skin typically have ancestral origins in places where the sun's rays have more power . Even though melanin is good for protecting against the sun, it does have its downsides, too. For example, melanin obstructs the body's absorption of vitamin D from sunlight. This can have a negative impact on health. So, if certain factors dictate that the body doesn't particularly need melanin , then evolution will weed it out. EDIT 2: A word
How does taste work? Why does a person A like spinach, but person B does not?
There could be a million reasons why someone doesn't like a food; maybe they ate it while feeling sick one time, and learned to associate the sickness with the taste. Perhaps they were made to eat something all the time as a kid so they're just totally opposed to eating it as an adult. The reasons could be either mental or physical affect a person's ability to smell, and therefore taste, and cigarette smoking has a similar but much less severe effect), and there are too many potential options to explain them all in detail. One relevant issue here, however, is that several aspects of taste are actually determined genetically. Some [bitter foods], such as grapefruit, only taste bitter to people who have the correct genes to taste such a flavour. So what you like, or don't, might have been determined for you at birth. A relevant side-note: there is a fruit, known as [miracle fruit], which temporarily blocks the sour receptors on the tongue, which basically completely changes the way you taste food. Lemons are sweet, beer tastes like chocolate milk, and so on. You should try to acquire some, and see how it affects you; it essentially allows you to taste things as if you were a different person and it wears off after a short time.
How are ancient structures buried?
In dry, dusty areas the wind blows in sand and sediment. Once someone stops living there to clean up it will build up. People also like to build on river banks and river deltas, very fertile for crops and easy access to water, but the river brings sediments and floods. In some places a populated site persists for hundreds or thousands of years, building on top of old stuff in layers. Without heavy machinery it's easier to leave stuff behind and build on top of existing foundations or layers.
Taxi Medallions, what is this system?
There are large areas of NYC where only a taxi with a medallion can operate and they limit the number of medallions that they allow to operate in a given year. This registration system generates income for the city and ensures that there are not too many taxis on the roads of the overly congested city. Uber bypasses this system. This means that they are not only competing in areas that are reserved for the medallion taxis, but they are not paying the proper fees and taxes to the city for operating a taxis service. They also do not have the background checks to protect passenger safety that taxis do.
If English is a Germanic language, why is it so difficult to read texts/understand speech in other Germanic languages?
English is the dirty bastard of Germanic languages. It is not German, it is rooted in the same early language group that gave us modern German/Dutch/Icelandic and the rest. English was heavily influenced by the Romance language group, particularly through old French, when the invading Normans brought it along. Toss in some Gaelic influence, more Latin for the 'scholarly' types, and you end up with a language that bears only a passing resemblance to its Germanic cousins.
What would happen if the Earth suddenly started spinning the wrong way?
If the earth stopped suddenly and started to spin the other way it would not matter because we would all be dead anyways.Suddenly? Everything would be killed/destroyed/flattened/thrown around from massive lateral G forces, Even if it takes a full second to reverse, going from 1670 km/h to -1670km/h at the planet's surface is ~340,000 G-forces. 49.2 is the highest recorded horizontal g force survived. Anything not anchored down to something that could survive that force would be flung across the surface of the earth at around 3000 km/h Depending on the type of force that would cause this to happen. The earth rips apart.

Why is it that big semi trucks last for hundreds of thousands of miles, but some cars start breaking at just about 100,000?
I myself work in the mining industry in australia. Recently was at a site near coober pedy in the middle of nowhere. Maintenance is a big part of it. The road trains we had are tri-drive kenworth 908s or something but would do 6 trips a day so close to 600kms a day from site to rail siding and back a few times but every time they pulled into the yard they were checked over. Fluids, belts, tires, filters and signs of new or increasing damage/wear. One thing I noticed was different was service intervals. Regular light vehicle gets serviced ever 5000kms or 10000kms the trucks all get serviced based on hours worked like 250hrs they get fluid samples taken, 500hrs tires rotated and belts inspected or changed, 1000hrs hrs they have the oils and filters changed etc etc so each time certain hours roll around its due for something. A fair bit would come down to driver abilities/abuse I would imagibe aswell', "There's a distinct difference in how diesel and regular gasoline engines work, that's part of it. Another part is semis aren't exactly meant for short errand travelling, they're built for long distance running. Lots less starting and stopping means less wear.Cars have the body as part of the structure. If something bad happens to that, it is a write-off quite often. That they are made for the cost does not help. Semis are built onto a steel channel frame. Their value makes mechanical repairs/overhaul prospective. Their operators often have a better technical understanding of their vehicle, more than the typical small vehicle motorist. The end result being it gets cared for. Plus there are mandatory inspectionsThe big trucks get lots of frequent, expensive maintenance. I used to drive busses with anywhere from 100-250,000 miles on them and they worked, but it took a full time mechanic to keep them running.
How can child-actors play in gruesome movies like Beasts of no Nation?
There are two routes. Danny from The Shining did not know it was a horror movie. His scenes were edited so that he did not have an idea that he was supposed to be in a scary movie. In Beasts of No Nation they went the opposite way. They were clear with the actors and explained what was happening. They made sure to have the support structure in place to make sure the actors knew what was happening and why certain things had to be done for the story. Remember that Abraham Attah was 13 when filming took place. The actors were able to tell what was real and what was fake and were able to distinguish between something bad and something acceptable.Child actors see the preparations for the seen. They see the greenscreens, the Camera team, the director. They see the same scary scene shot a couple of times. They speak and joke with the other actors and the prop and mask team. Even in Horror movies, scenes have to be filmed over and over because the actors just burst out laughing. Also they see the prop and mask prepration, so for them a scene that has for example, somebody loosing an arm, the don't see that isolated. , they see the actor getting a prop arm, fake blood packets attached, etc.The really scary parts like atmosphere, sound and lightning are only including afterwards. So the child actors have a very good grasp on what is reality and what is fiction. If they watch the movie later they usually also don't see the movie isolated. They are reminded of how they shot that scene, and how they attached the blood packs for example. I remember reading about one child actor who burst out laughing during a rather intense horror scene because she remembered how in one take the monster actor started laughing so badly that he fell down, which looked very strange in his costume.
Why do people in poverty stricken countries continue to reproduce even though they know their children are likely to starve to death?
Because if you keep reproducing, maybe you will get lucky and some of your kids will grow up to adulthood, get a wife, and farm the scrap of land you own and provide for you when you are old and can't work anymore. You know, like how people did for pretty much all of recorded history.
What happened to all of the sweepstakes?
They were replaced by online contests through web forms and social media, which are faster, easier, and cheaper to both organize and participate in.Don't know about the US, but in the UK, this generally stopped after it was discovered that the TV shows where rigging the contests. _URL_0_", 'They ran out of money because fucking Ed gave it all away to anyone who would open the damn door.
Why do people not get electrocuted when touching a charger?
There are two ways in which chargers prevent electrocution. The first one is that everything that can be covered in plastic or rubber is covered in plastic or rubber. Electricity can't flow through plastic or rubber. If something on the outside of the charger or device is metal, the charger will have a third metal strip which allows electricity to be "grounded". Electricity flows on the path with the least resistance to the ground, so if is a choice between flowing through you or flowing through the metal wire to the ground, or will choose the wire and you won't be electrocuted.Do you mean a phone charger? If so - one reason is the voltage is too low. Your skin is not a great conductor of electricity, and it takes a pretty good amount of voltage before you can get any real power flowing through you. Think of voltage like water pressure. If you want it to go through a path that is not a good conductor - then the pressure has to be high too if you want to get a reasonable amount of water to go through. A small amount of current may flow through your skin if you touch the connector the right way, but it is such a tiny amount of power it is basically harmless . And as u/_Awkward_Llama mentioned, they make sure everything is covered up - there *are* dangerous voltages inside the charger, but they protect that from the outside world. Does that help to answer your question? Edit: Something to add - if you get a cheap charger with no safety approval, you could get shocked. They could potentially be dangerous .
Why is the word "'nother" so typically said after "whole"?
This is an infix, a word inside a word to add emphasis . It is placing "whole" inside of "another," a-whole-nother. The only other common infix in English is "fucking," e.g. abso-fucking-lutely and god-fucking-dammitit is an English colloquialism typically the proper way would be either a whole other --as someone has mentioned another whole problem and yes, as someone else stated, "fucking" is another common American English infixI think we just forget that "another" is a compound word of "an" + "other". When we say it aloud, I think our brain breaks the syllables after the "a" and we think of it as "a" + "nother", creating the notion in our brain that "nother" is a word.
Why is deforestation such a large problem if it only affects the country where it takes place?
First, it doesn't only affect that country; the entire earth benefits from having a healthy ecosystem. Second, the health of countries is intertwined; a desolate country that is economically desperate is going to affect adjacent countries.
how and why animals age differently to humans, and how we are able to calculate their age equivalence?
If by "Age equivalence" you mean something like "dog years" that's simply a rough approximation. If a human lives 10 times longer than a dog, on average, then 1 \'human year\' is 10 'dog years.\' It really has no particular accuracy beyond a rough demonstration of lifespan, and tends to be wildly off on things like 'maturity\' or what notGenerally speaking longevity in animals is determined by proteins that are found in long-living animals . These proteins help with repairing the body and controlling things like metabolism . As far as calculating age equivalence it is very easy, find the average life of two animals and divide one by the other. So if a human lives for an average of 80 years and a cat lives for an average of 12 years than a cat year Is roughly seven human years.
Why don't invisible rays like wifi and satellite hurt humans or animals?
Does shining a flashlight at you give you cancer? Because visible light is actually on the "more dangerous" side of radio waves. Radio waves, like Wi-Fi, are the same thing as beams of light. The only difference is that we have special chemicals in our eyes that react with the electromagnetic waves we call "visible light". On the "less power" side of visible light on the electromagnetic spectrum we have infrared and radio waves. These are harmless. On the "more power" side of visible light, we have ultraviolet radiation , X-Rays, and Gamma Rays We are all bombarded by "invisible waves" all the time. Sound waves, light waves, etc. Basically, just because something has to do with electricity doesn't mean it's bad.First you have to know why some invisible rays do hurt humans and animals and give us cancer. They knock electrons off of atoms, causing random chemical reactions. If these atoms happen to be DNA molecules, it can damage the DNA, and has a small chance of leading to cancer. In order for this to happen, the rays have to have enough energy to knock an electron off. If they don't, pretty much all they do is heat stuff up. Radiation that's high enough energy to do that is called ionizing radiation. The lowest energy it can be is ultraviolet light. So you can get cancer from ultraviolet light, X-rays, and gamma rays, but radio waves, microwaves, infrared light, visible light, and everything in between don't give you cancer.
RobinHood: SolarCity and Tesla merged. My SCTY shares vanished.
Your SCTY shares will be replaced by Tesla shares at a rate determined by the conditions of the deal. IIRC it's 0.11 TSLA for every SCTY but I might be wrong.
Why do sitcoms have laughter tracks?
People tend to laugh more when they hear other people laughing. Laughter is a pretty social phenomenon. Most people are more likely to laugh at a show if it has a laugh track. I don't know how that equates to viewership, but it obviously has some effect or they wouldn't do it.
Why does this appear to move?
It's an illusion that happens because we're constantly moving. Our eyes are jumping around the page while our body is twitching. If you stop all the movement and just stare at the picture, you'll notice it stops moving, too. Pretty sure it's a myth that the picture will move faster if you're stressed though. They probably say this because people sometimes make more rapid movements when they are stressed.
Why do we have that uncomfortable feeling when sleeping with limbs uncovered or hanging out of the bed?
Evolution. People who didn't get that weird feeling when dangling their limbs from the trees they were sleeping on were killed by cheetahs.
why are most of the animals born with good enough insticts to survive at birth while humans are so helpless?
Humans are building a biological supercomputer, that takes time. Our great ape cousins are also pretty useless at birth, as are a lot of other mammals and birds. They're developing complex brains and behavior systems that can't be completed as quickly as basic body development.Part of the reason is that humans have to be born premature, so to speak, while that massive head can still fit through the birth canal.

How do police catch cars using false licence plates?
if you get pulled over, they run your plate and its not listed/different than what your car is you get in a shitton of trouble. you have to be really smart about it, because getting caught with a fake licence plate is often worse than whatever crime you were hiding from', "They see a car and are suspicious for some reason, so they run it through the database. The license doesn't show up. Or, a car is caught on red light cameras and doesn't show up in the database. They note the make, model and color of the car and the location, and look around in the area for a match.
How does a (particular) flock of migratory birds decide *exactly* when its time to go?
I'm not an ornothologist but I'm a human, and all ornithologists are also human, so that's gotta count for something, right? I'm guessing all birds have a number of "thresholds", with some variation from one member of the flock to the next. A: the temperature/conditions at which the bird would rather stay, but will start migrating if most others do B: the temperature/conditions at which the bird would like to migrate, but doesn't want to be the first C: the temperature/conditions at which the bird says "fuck it, I'm going" As migrating season begins, some birds will start reaching their A threshold, and nobody does anything. A little later, nearly all members of the flock will have reached A, and a few will be at B and getting a little antsy. Then, one will reach C, start flying, but only a few were at B and will follow, whereas the majority was still at A, and so the impatient ones will say "fine, whatever" and come back, seeing that nobody followed them. This might repeat a couple times, with a little more followers, until critical mass is reached and everyone just goes. Disclaimer: there is a very high probability the above is absolute hogwash.
Can someone please explain the general ideas behind Healthcare Reform and why it is so controversial?
Some people think every citizen in a rich country ought to get health care, even if other citizens must help pay for it. That would require the government to collect money and then spend it on health care. Other people think it isn't fair to make one person pay another person's health insurance bill, or that the government will do a bad job and waste the money. Government health insurance is already happening, in programs called Medicare and Medicaid. Healthcare Reform would make *more* of it happen. But people who think government is wasteful would like *less* of it to happen.
What does a volume knob physically do inside a speaker to increase/decrease the volume when you turn it?
You're actually controlling a variable resistor, a.k.a. a potentiometer -- which can control the amount current in a circuit. Lower current = weaker sound, higher current = louder sound. Basically, when you turn up the volume, you're allowing more electricity to flow through the circuit that leads to the amplifier.The knob is connected to a shaft that spins a \'wiper\' over a little strip of carbon. The wiper is basically a tiny wire that turns. On either end of the carbon is another wire, usually connected to source or ground . Because resistance varies with length, moving the wiper varies the length. Changing the resistance let's you control how much signal is passed through the resistor and how much is burnt off as heat. Turn it all the way one direction and all the signal goes through, turn it the other way and all the signal is dissipated across the resistor. Now that's really inefficient. You're amplifying the signal a bunch, then either sending it forward or wasting the energy as heat. A solution is to use feedback. The way it works is the input to the amplifier circuit is "differential" meaning it amplifies the difference between two signals. The resistor controls that difference. It brings the efficiency way up.
Why do people live in Places like Barrow, AK
Some of them might be Native or just have grown up there. For the most part, people live up there to harvest natural resources. Alaska produces a shitload of oil & has lots of mining. It's a rough place to live, so they make a lot of money. Many people that live in Alaska working those industries will work a few months at a time & then come down to the West Coast for a few months to enjoy their money before going back to work.
Why do processed food comes with tag saying "xKcal". How would a bottle of 500ml of fruit juice have 43,0 00 calories(43,12 kcal ).
Humans need 2400 Kcal per dayThis Food probably has 43 Kcal per 100ml Humans are lazy and tend to say "Calorie" when they mean "KiloCalorie"Because there are [two "calorie" units of measurement]. The calorie is the energy that goes into one gram of water, and the gram is technically the base unit of measurement in the Metric system. But for day-to-day purposes we use kilograms, so because the kilogram sees more use than the gram, the Calorie = 1 kc is actually what gets put on the packaging of most foods. Technically, 100 Calories is enough energy to bring a kilo of water to boiling. Quote from [here]:Humans do not generate much power. Think about a person who consumes 2000 Calories in a day. Every Calorie from food is equal to 4200 joules of energy. Used over the course of a day , this person uses an average of 97.2 joules a second, meaning they have an average power of 97.2 watts. Certainly a person could juggle quite a few hamburgers, but in the end humans only average the power of a bright lightbulbAmusing how it says “mango pulp & sugar” instead of “sugar, mango pulp” which is a more likely situation. Most of the energy is from the sugarA kilocalorie is what we refer to as a Calorie. If a nutrition label says 100 calories, it actually means 100 kcals.
Why does my voice sound weird when I talk through the fan?
Your voice is made of sound waves and the fan is chopping them up as you talk through it.
What's the difference between Linear Synchronous Motors (LSM) and Linear Introduction Motors (LIM) on launched roller coasters?
"Induction" not introduction. The synchronous motors generally know where the cars being accelerated are. The LIMs generally don't. LIMs are more grunty at the start, but can't generally get the cars going as fast by the end of the track. LSMs aren't as quick off the line, but can sustain higher speeds in the long run.
Why NetFlix's "Recently Added" column has all the newest releases, while it's "New Releases" contains mostly movies that have been on NetFlix for months-years.
It's based off of your recommended shows/movies so if you have a specific taste, the newest movie in that category might be a year old.
How does Eye color play into attraction?
Looking into someone's eyes can reveal a lot of information about how that person thinks of you. For example, if you look into your date's eyes and they dialate, you are *much* more likely to think they have pretty eyes. This is because eye dilation is a sign of arrousal in this context. Similarly, pupil dilation shows interest in other contexts as well.

Why are AK47s and other Kalashnikov weapons so renowned? How do you make your weapons simpler and hardier than the other guy?
The simplicity mostly comes in the form of HUGE tolerances between parts inside the receiver. If you open an AK up, there's a ton of empty space inside the receiver, and very few moving parts in the trigger group. That allows you to put all kinds of dirt, gunk, snow, sand, pebbles, dust, etc. inside the thing without gumming up the works. They're also incredibly easy to maintain because of these loose tolerances and the relatively few parts. If you can open the receiver, dump out any crud that's accumulated in there, and slather some motor oil over the moving parts, you're good to go. As to how they became so ubiquitous, that's partly because of the easy manufacturing process , and the fact that the USSR absolutely *loved* to stick its nose into other countries' business; even moreso than the USA did. They had a habit of mass producing AKs and arming little pissant rebel groups all across the globe, and the gun worked quite well for that purpose because it's so easy to maintain, and so resistant to damage and jamming. A barely-trained nobody could be turned from peasant to warrior with the addition of an AK. So basically, it comes down to the fact that the AK was easy to make, easy to maintain, and tough as hell because that's what it was designed to be. The USSR war ethic at the time was all about mass production of overwhelming force, and the AK was designed to fit in that niche.
Where do emergency counselors come from?
[This page] from FEMA's website helps to answer your question. Crisis counselors are funded by FEMA but organized and implemented by the state. [Here], for example, is New Jersey's Division of Mental Health Services page. Although most counselors have a counseling background, it isn't required. You apply for the certification, complete your training, and are then called upon as needed. It is not a full-time job.
What is the difference between oil drilling and hydraulic fracturing (fracking) as well as the difference between the methods used?
**Fracking:** imagine that the oil you want is soaked in a sponge. But this sponge isn't squishy , but it's also easy to break, like glass. If you drilled a hole through this "sponge" you will only be able to reach the oil in the pockets really close to the hole you're drilling. But imagine drilling a hole through the glass sponge sideways, and then blowing into the hole *really* hard. This will make the glass sponge crack. Oil will now leak down through those cracks and you can collect it from the hole you have drilled. Drillers are trying to get the oil by using liquid chemicals to crack the sponge, and these chemicals could leak through the cracks. The people living nearby are worried that the chemicals will hurt the land and water, and in turn hurt the animals and humans as well.
how did the very first life forms develop?
Well we have some idea. Infact, you could create life in you own kitchen! its very simple: take a tank, fill it halfway with purified water then, get a canister of pressurized carbon-dioxide. spray some into the tank, then quickly cover and seal the tank. Now, all organic life is composed of four main elements: Carbon, Nitrogen, Hydrogen, and Oxygen.^^^and trace other elementsYou have these elements already in your tank: water has hydrogen and Oxygen, and the air contains Nitrogen, Oxygen and Carbon. Now all you have to do is wait. The molecules will bump into each other, transfer valence energy and electrons to each other. This will break and create bonds between the atoms. eventually, all four elements will bump into each other and form carbo-hydrates and amino acids. Now wait a bit more. These amino acids, carbohydrates, etc etc will keep bumping into each other, exchanging bonds, and eventually a molecule of Neuclic Acid will form. And guess what that Acid is? Yes! It's ALIVE. This is basically how it all started. I could go into more detail if you want. Keep in mind, I'm no astrophysicist. This is shit I've learned from watching Bill Nye the Science Guy. You can probably get way more accurate info on google.
Does FLAC compression have different bitrates?
FLAC has different levels of compression but they relate to how much CPU/RAM is used in the compression rather than the target bitrate. Since FLAC is lossless, it's not really possible to target a bitrate. As far as file quality goes, FLAC is limited by the quality of the input. If you have a CD, the quality will always be 16-bit, 44.1kHz stereo - if you start with higher or lower quality audio, you can compress them.
Why did people think Beanie Babies would be so valuable?
Collector items tend to be valuable as they become rare. These where made almost solely to have this kind of economy where they can be traded and collected. Unfortunately for them though the economy wasn't handled correctly and they quickly became over populated and/or people moved on from them.Things have value because people want them. Many collector things have had value years after they were made, because, for one reason or another, people wanted them. Examples include early Star Wars merchandise, Baseball cards of famous players, etc. People thought Beanie Babies would be the same thing, and so they were willing to pay a lot of money for them; because of the expectation that they would be worth more later. This was fueled by the company that made them, which created "limited edition
Why does gas mileage take a nose dive during cold temperature? Is there an agreed upon temp where warming up the car is required?
There are a few things. 1) the above 2) The engine has an optimal temperature below that temperature it runs rich to warm up faster.3) cold air has a higher oxygen content so you need more fuel to create a good burn. More fuel means worse mileage. This only really translate to 5-10 percent difference but it all adds up.Due to the oil and other fluids getting goopy in the cold. Yer not alone in askin', and kind strangers have explained: 1. [ELI5: Why do cars have significantly worse gas mileage when it's cold? ] ^1. [ELI5: How does the changing temperature outside affect my car's gas mileage? ] ^
Why are many manholes placed right in the path of a car's tire on roads?
I don't know for sure but I'd guess it's because the tunnel is under the road and the ladder down is on the side of the tunnel. Which more or less places the ladder under your tire, apparently.Why is the worst possible location or even a bad position. Have you notice a lot of manhole coverts that breaks or get damages by cars? There is a good reson that they are spread out over the road. There are often multiple types of pipes in the road that follow the path of the road especially in cities. So the man hole covers has to be there because the pipe is directly belowAt one point, the covers may have been in the middle of the lanes. The road could have been expanded and lane lines moves, making the covers in path of the tire. It could also be that it was the best/most cost effective way they could work it into the sewer.
Do caterpillars know that they are going to become a butterfly? If so, how?
It's a common mistake that people sometimes make to try to apply human levels of intelligence to insects. Insects are not self-aware. A caterpillar does not even know that it is a caterpillar. It is aware of the general shape of the surface it's on, and it feels hungry around things it can eat. That's really the extent of it's cognitive powers - it doesn't know things like how much it's eaten recently, or if there are usually predators in an area. And it certainly doesn't know what's going to happen to it after it's done with it's metamorphosis.
What's the difference between a street, Avenue, way, run, road etc. When used with street names?
Avenues are often major roadways, courts circles closes and lanes are almost always dead ends, boulevards and parkways are multiple lanes roads.
Why is Africa the least developed continent if humanity started there?
Well, you can contrast Northern Africa from Southern Africa. For most of history, Northern Africa wasn't any less developed than the most developed parts of Europe or the Near East . In fact, Carthage and Egypt were among the wealthiest, most advanced civilizations in multiple eras right up through early modern times. The difference between North Africa and the rest of the continent? The Sahara Desert is a giant, awful sinkhole that killed 99% of cultural exchange or trade relations between most of sub-Saharan Africa and the outside world, except for some contact in and around the ports - which more often resulted in slave trading than productive cultural exchanges. Isolated cultures pretty much never do well on the scale of human development.
"State Police Aircraft Used in Speed Enforcement"
A few ways, the easiest is, sometimes you'll see white horizontal stripes on the side of the highway. Each one of those stripes are a mile apart. If you cross 2 white stripes in 1 minute, you are going 60 miles an hour. Under 1 minute, and you might be speeding. Some other aircraft are fairly slow, and can fly at 50-60 mph, so they match the car's speed, and from that they can measure the car's speed since it equals the plane's speed.
When you're drinking from a bottle, what stops more water from flowing down through your throat until you swallow?
It's the back of the tongue. If you are taking consecutive swallows it is the base of your tongue. See this swallow study link. The liquid shows up black, and the person drinking holds the liquid in their oral cavity with the back of the tongue. _URL_0_ It's not the epiglottis or anything else. The epiglottis helps close the airway and direct the food down where it's supposed to go. And chugging is a different kind of swallow where the person consciously closes their airway, opens up their upper esophageal sphincter, and lets the liquid slide down. People who chug are just pouring it down.

Why do we add salt at various stages of the cooking process. Why not just add the seasoning all at once at the end? Does this have an affect on overall taste?
It can have an effect on moisture and toughness of meats, salting too early can draw out moisture from the meat.
How are mAh (and amps in general) and voltage related in terms of batteries?
You can think of voltage as a measure of electrical "pressure". Amperes are a measure of the number of electrons, and voltage is the concentration or "pressure" of electrons. Imagine water in a pipe. if you increase the size of the pipe, the "voltage" drops and the "amperage" stays the same. if you decrease the size of the pipe, the "voltage" increasesA milli-amp hour is how many milli-amps are drawn down in one hour. If a battery is rated at 2400 mAh and the device it is connected to draws a steady 100 milli-amps per hour, the battery will drain in 24 hours under ideal conditions. The rated voltage of the battery is based on engineering specs and isn't really related to mAh for the purposes of this discussion. But, since a "battery" is technically several cells that are soldered together, you could add a cell, which would raise the voltage and the mAh rating, but it wouldn't work in the device, so it's a moot point. Edit- It occurs to me that the question of batteries with different mAh ratings for the same device, like a high capacity battery for your cell phone, may come up. Less internal resistance due to better manufacturing materials and/or processes. Ohm's law. Voltage = Current x Resistance. If voltage stays the same, but current goes up, it must be because resistance came downCurrent is a measure of the amount of charge is being transmitted every second. Essentially a battery can only store so much charge. Essentially a 5000 mAh battery , can transmit at 5 Amperes for 1 hour or 0.5 Amperes for 10 hours. Voltage is a measure of potential energy in each electron per Coulombe . If something has a higher voltage, that a single unit of charge has more energy associated with it.
What are the differences between a 12MP DSLR camera and a 12MP point and shoot camera in terms of quality of shots?
Alright so there are a few things going on here. First, megapixels is no what determines the quality of a photo, but rather the clarity it will up to a certain size. For example, if you find a picture online you want to use as your computer wallpaper that is 800x600, but your resolution is 1440x900, the image will not look good. It will be stretched out and weird. Also, the reverse is true. If you take a large picture and crunch it into a small area, clarity is lost. Second, you cannot attach a lens to point and shoot camera. DSLR's generally come with a stock lens, and then you change the lens depending on how far away the target is. Next, shutter speed is generally higher on a DSLR than a P & S, so you can take pictures in quicker succession. Some P & S have a burst mode that takes 10 to 30 pictures or so but an DSLR will generally take the pictures in quicker succession and most of the ones I use to sell didn't have a limit of photos. ISO, exposure, and aperture are relative to the specific situation you are taking the picture, so if both cameras have the optimal settings for a specific setting, that won't be an issue. Last, DSLR's have larger image sensors, which is what determines the actual image quality. I take it you are thinking about buying a DSLR but are not sure?
why are mattresses so expensive?
Middlemen. Let's say I make a pillow, and I want to sell it, but I don't know who I would get it to. So I tell my friend, Mr. Middleman, "Hey, find someone to sell this to. I require that **I** get $8 out of it. Okay?" He says "Okay." But he thinks to himself, "If *I'm* gonna be the one to find someone to sell this to, **I** better make some money too!" So he ends up selling it to Bed Bath & Beyond. He sells it to them for $20. So BB & B wants to sell it to you, and they want to make a profit. So they sell it to you for $30.If I sold it to you, It 'd be $8.If Mr. Middleman sold it to you, it 'd be $20.If you got it from BB & B, it was $30.Now Imagine that I made a mattress.And imagine that there's a zero on the end of ALL those numbersyou spent 1/3rd of your life on them, they should be of reasonable quality.
Why did Microsoft stop supporting/updating Internet Explorer for awhile, but then later decided to resume updates?
Microsoft never stopped supporting Internet Explorer. There was a period from 2001-2006 where Microsoft didn't release a new version of Internet Explorer but that was because they were doing a security audit of all of their software after things like the Blaster worm caused a lot of damage, not because they stopped working on them.
