Why is a photocopying machine so huge compared to a normal colour printer?
|
There are very small photocopiers too. On the large ones, most of the extra size is for complex paper handling: several large supplies of different sizes of paper; a collator that can make 10-20 separate copies of a whole document; sometimes an auto-stapler; a high-speed jam-resistant paper feeding and duplexing mechanismIt is not necessarily bigger. You can get photocopier that fits in your bag and you can get printers that take up the room. But even the big photocopier have a modest sized printer and a modest sized scanner. Most of the space is taken up by rollers and shelves for moving and manipulating the paper. And this part is optional. But there is a tendency that on smaller printers you omit the scanner part to make it more compact but for bigger printers you have the scanner module as it does not matter that much and is quite useful. So it is not so much that photocopiers tend to be bigger then printers but more the fact that big printers tend to be photocopiers.You see photocopiers in office environments. They are required to handle a larger load of workflow so require more storage, and other functionalities like scanning. Your average home printer is small because it needs to take up less room to fit in your computer room at home and it doesn't get used for 10 hours every day.

How do we know that two identical snowflakes have never existed and never will?
|
The reason we can say no two snowflakes are identical with such high confidence is due to the absolutely disgusting number of possible differences that can occur in the formation of a snowflake. To put it into perspective, take a deck of cards and shuffle it. Statistically speaking, the order in which the cards end up has never existed in the history of mankind. This is because a deck of 52 cards can have 52! different ways to end up after being shuffled. Thats 8,065,817,520,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 different combinations, and thats just with 52 variables , this number is so big that our monkey brains actually don't understand just how big it is. Assuming "identical" here means down to a molecular level, then the formation of a snowflake would have millions, or billions or trillions of variables, i.e a number so big thatwe can just about say "yea that's not happening, wrap it up and go home"We don’t in the sense you are thinking of. They mean statistically negligent. Like if I told you that you would never get struck by lightning while winning the lottery. Technically speaking there is a chance, but the odds are so low we are comfortable verbally using a definitive statementThe statement is trivial if you think about it. No two objects of that size are ever going to be ‘identical’ without some qualifiers, at what size-scale do you stop comparing them atom by atom?

What is up with the child entertainers of North Korea?
|
Yes, completely true. These kids are placed into these programs starting at a very early age and usually are "performers" for a while. People disguised it as a job of high honor and privilege but these kids go through a hard reality. For example, if you have ever seen the "mass games" in NK, there are thousands of child performers. These kids aren't given much food or water. They aren't given sufficient bathroom breaks either. This causes the children to have developing cystitis or other urinary tract ailments. If the kids do not perform as they could, the most common consequence is physical abuse with a stick.

Which is a better, more practical healthcare option?
|
At 630 a month?You should probably be looking into Medicaid. The Obamacare marketplace is for people that make too much for Medicaid. Part of this rollout was also a boost to how much you could make and not still qualify for medicaid--however, many states chose to not take this option. The federal government was even going to cover this increase in Medicaid costs for the first 2 years, but cannot force the states to change. If you are in one of those states, this is very difficult for you, and I wish I had a better answer than talk to your congressmen.

How do birds fly from standing still?
|
It certainly is not effortless, their wings are part of their body and flapping hard enough to shoot off the ground takes a lot of effort. Their bodies are very light and their wings very large comparatively so a big strong flap pushes enough air to propel themselves.The available lift of a foil vs. airspeed flowing over the foil is not linear, it goes up geometrically with the airspeed. The powerful first down-flap of the birds wing is done at a perfect angle of attack and a higher than normal flapping speed and power and it creates a lot of lift, then the bird will line up the wing's angle of attack into the flow of the air during the up-flap so the wing develops no lift at all because that would push the bird back down. The wing is again twisted to develop maximum lift from airflow and flapped down hard again, twisted to a no-lift up-flap, down to max lift down-flap, etc. These first few down-flaps are a very power-intensive undertaking and require an unusual wing configuration but it only needs to be done for a few flaps, forward airspeed begins to become more available to the bird and the flapping soon requires less intensity, and ultimately, with some good soaring birds, very little flapping at all. TL/DR; birds instantly change their wing's angle of attack like wizards.

Besides bragging rights, for what reasons are countries still "racing" in space exploration?
|
imagine being in 2nd grade and everyone had home packed sandwiches and juice boxes and you were the first kid to have that baller ass pizza lunchable and caprisun combo. not only are you the coolest kid in the lunchroom, but you could trade that caprisun for way above its value---a juice box and a bag of oreos---because you're the only person who has it, thus increasing its rarity and value.

how does the taliban manipulate people into thinking that there going to be accepted in heaven if they remove education or commit suicide bombings
|
People from "1st world" countries often don't realize how much more education and knowledge they have access to than people from 3rd world countries. Knowledge is truely power in most circumstances. Groups like the Taliban take advantage of the fact that certain peoples only education comes from their parents or elders, and this education can be easily manipulated to support their agenda. It is not that hard to threaten the elders of a community that has no TV, radio, internet, or other access to the outside world in order to force them to support the agenda of the Taliban . As the young get older and come of age, all they know are these teachings, so to them they are the true way of the world. For groups where this will not work, they just threaten and deliver death to any who disagree. After you watch a few of your friends or family executed, you learn to act a certain way in public, which can eventually lead to brainwashing yourself into actually believe it Removing education is a tool to manipulate people. They don't believe that having a good education is stopping one from getting into heaven but instead they remove education to stop their recruits from developing critical thinking skills. An uneducated person is much more easily convinced to don a suicide vest and believe he's doing it for 72 virgins. An educated person will probably pass on that "honorable" "opportunity".

How/why did China's population grow so large so fast?
|
Holy crap, something I can actually answer! From what I remember in my Chinese history class, Leader Mao wanted a strong army and felt a large population was necessary. Lots of campaigns were led to convince people to have as many kids as possible. It didn't take long before the country had a massive population. The only problem was lack of food. A massive famine came and wiped out a large amount of people, but not enough to even out the population. To this day, they've never really recovered, and even have laws in place to stop you from having too many kids. Edit:_URL_0_ I found a source!

What is in magnets that make them magnets, as oppose to a piece of iron or other metal.
|
Permanent magnetism is caused when most of the electrons in an object have their spins aligned in the same direction. There isn't really a way to ELI5 it.A magnet is any object that has a magnetic field. The space surrounding a magnet, in which magnetic force is exerted, is called a magnetic field. If a bar magnet is placed in such a field, it will experience magnetic forces. However, the field will continue to exist even if the magnet is removed. The direction of magnetic field at a point is the direction of the resultant force acting on a hypothetical North Pole placed at that point.When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrical charges. A magnetic field of a bar magnet thus results from the motion of negatively charged electrons in the magnetA piece of iron is broken up into microscopic *domains*, little bits that act like magnets, but point is every direction and cancel each other out. When a piece of iron is magnetized, the domains are aligned so they all point in the same direction. Once they are no longer cancelling each other out, the magnetic properties are apparent on a larger scale.

Where do "smells" go after they have dissipated?
|
Think of a glass of water being the gaseous area around you The smelling zone You now drop on drop of liquid food colouring into the glass, the dark heavy first impact area of that droplet represents, let's say a fart. After the initial impact of the fart it begins to dissipate into the rest of the water, trailing off, getting fainter and fainter. Fast forward 5 minutes and you can only barely see a hint of a slight mention of colour left in all of the glass because it's spread so far out that it's like it's not there, but it's just not discernable any more.

How come we don't get burns (or worse) on water slides?
|
The water acts as a thin barrier between you and the slide, so that reduces the friction to the point where you wont be burned. As long as you're wet, you should be ok with a brush against the side , but sliding down when everything is dry would result in some serious friction burns.

How is it possible for pasta to stick together in water when it is being boiled?
|
You are boiling the pasta in too little water, you really need at least a gallon of water at a rolling boil. What's happening is you are saturating the water with excess starch, it gelantizes and turns into glue. literally, it's library paste.

Why do humans need a variety of sustenance in order to stave off malnutrition, but many animals can live on only a single food?
|
We eat a variety of foods to live *optimally*. In theory, you can survive off a singular diet, and as long as you get enough calories, you will live. However for optimal brain development in children, for the longevity of our bodies and living many years without disease/illness, we eat lots of different foods. For example, if you get very low amounts of calcium, you get weaker bones which will affect you as you start to age, however for most animals that is not a concern because a predator is likely to eat you by that time anyways.Theoretically, humans can live on a very simple diet . But we *like* having a more complex diet and it is better for us. The bare minimum diet that we need would be a certain number of calories and the occassional protein source, like meat or beans or nuts. There are also trace vitamins and minerals that you should have but it'll take you a while to die from it if you don't have it.

If climate change is such a massive problem, why can't the government create laws to begin to limit the usage of items that increase greenhouse gases, until they can gradually completely ban it?
|
In economics, it's called an "externality" when the impact or cost of some action will affect a person *other* than the person who's performing that action. Air pollution is a famous example of an externality. Factories and trucks produce large amounts of smog that can affect plenty of people who had nothing to do with those factories and trucks. Companies who sell these products will generally resist efforts to limit that, because in their mind it's "not their problem". Climate change is similar. There's an overwhelming scientific consensus that climate change will become an enormous problem for us, but there's no economic incentive for companies and countries to change that *right now* -- the harms and benefits won't be felt for many years, and when you're asking companies to spend billions of dollars on something they're going to want a more direct benefit. It's one of those circumstances where short-term individual interests are at odds with the long-term common good. Elected officials are hesitant to act because they would risk losing lobbyist support and because voters aren't convinced this an important issue.You wanna tell Americans they can't do something? Good luck with that.

How can a fired ex-employee sue their boss for discrimination? Couldn't the boss just make up a reason for firing them (attitude, wardrobe, etc)?
|
The person suing would take all the evidence they have that it was disfrimination, the person being sued would take all the evidence they have that it was another reason, and a judge would decide whose story is more likely. If someone believes they were fired for discrimination, the boss most of done some discriminatory things. That likely means there's evidence. It's possible, but very unlikely, there would be no evidence-- until we perfect telepathy, we'll never have a perfect system that can decide court cases with no evidence either way.

I'm from the UK and only heard about Comcast recently; what is so bad about it?
|
Cable company and ISP. People get mad at their admittedly poor customer service and their state reinforced local monopolies . Then a bunch of people whose mothers pay their cable bill come to Reddit to complain that they aren't getting free gigabit to their house.They are a movie/tv company [NBC, Universal , Fandango, Hulu, Focus Entertainment, Syfy, G4, E!, Bravo, USA, and more] that also is a television/Internet/phone provider in the US. They are known for shitty customer service and screwing over customers . Many Americans have no choice but to use their service because in many places, they are the only option_URL_0_ Still the best explanation for comcast that there is

How do the battery meters in phones/laptops/other electronics 'adapt' to changing battery life as a device ages?
|
Short answer - badly. longer answer - they monitor the amount of energy that they are using and cross reference it with the measured battery voltage. If the battery voltage gets low enough that it's a good assumption that it's nearly dead, then the device re-calibrates its own estimate of what the capacity is.

Bodybuilding, power lifting, strongman, crossfit training, calisthenics, etc. What's the difference?
|
Largely it's the goal of the training. Power lifting is strictly about developing strength for specific types of lifting. Body building is about developing muscle tone and size, but not necessarily strength. Calisthenics tends to use lighter or just body weight, with a goal toward overall aerobic fitness. Crossfit, at it's best, is a mix of weight lifting for overall strength and calisthenics for aerobic fitness. Different sports and goals require different training methods.

If an overweight person goes several days without eating to lose weight, what are the unhealthy side effects this has on the body?
|
Fasting is fine, short term fasting with good liquid intake is not going to be detrimental for a healthy individual. Good luck keeping it up though, the will power required is astronomical.Fasted for two weeks once, the mental clarity after a few days was so intoxicating and the most alluring part of it. After three days weight just melts off. If you can get to sleep you don't wake up hungry.Nothing really. However if they didn't eat for a month or so, they could become deficient in necessary vitamins and electrolytes. However, "Starvation Mode" is a myth perpetuated by weak-willed, spineless fat activists.The nutrients. They aren't stored in your body. you can go maybe a few days without one with anything longer would lead to related issues with deficiencies. If say you didnt take enough enough vit C, you get scurvy. Thats why a balanced diet with fewer calories is always recomended instead of not eating for a few days.

Why is my belly button lint always navy blue, regardless of my t-shirt color?
|
Overwhelming the clothes you wear are of darker colours, blue, grey, black etc. The lint is build up over time. Dr Karl actually studied this. He recently did an AMA too, but I cant find it for you now. Interestingly, if you shave or generally have no stomach hair you dont get belly button lint. Think 'Sarlacc Pit', as the fabric rubs againt the stomach it's motioned toward the centre.

How can London Heathrow get by on just TWO runways!?
|
I would assume those are just the primary take-off/landing runways. There is surely a series of smaller runways used for moving "into position" and taxiing around the airport. *Theoretically*, you could have a plane starting take-off while another is just leaving the ground on the other end. I'm sure they are also quite efficient, but that doesn't mean other airports are redundant in their designs.Well we also have London Gatwick, London City, Luton, and Stanstead airports. Southend and Oxford airports are also pretty close compared to some other international airports I've been to over the years.

Pain tolerance fluctuations (NSFW)
|
When you're doing the act, your adrenaline is flowing, your endorphins are up your body is basically focusing itself on the act and tuning out other stimuli as much as possible. It's the same reason a punch hurts less if you're sweating and warmed up than if you get sucker punched. Your body's in fight mode, and it's tuning out distractions like pain wherever it can.

The battle of Stalingrad (lack of Russian armor)
|
Most of the fighting in the battle of Stalingrad happened inside the city itself where armor is not all that useful. Tanks are powerful in open country because they can bust a hole in the enemy's lines and then move into their rear areas and wreck their command and supply units. Inside a city a tank is basically reduced to being a mobile pillbox, and one that's fairly vulnerable at that. [Operation Uranus], the follow on operation that lead to the encirclement and destruction of the German 6th Army made extensive use of armor. In this case Soviet tanks broke a hole in the flanks on both sides and then raced to meet in the middle, forming a pocket that trapped the bulk of the German forces inside. This kind of high speed high impact fighting was what tanks were meant for, so it's how the Soviets used them in this case.Armor in general NEVER does well in urban areas. Armor is most effective when large formations can use their speed to maneuver around strong points and concentrate where they are most useful. A city allows none of that to happen. And gives all the advantages to the defender.

How do (did some) hunting tribes survive living of an all-meat-diet (like some Inuit tribes)?
|
They eat a lot of things like organs, fat, and bone marrow that contain more nutrients than the normal cuts of meat you 'd find at the grocery store. It's entirely possible to meet your nutritional requirements on a totally carnivorous diet if you're willing to eat the "gross" parts of animals.Did you ever eat a seal's eyeball? Inuit do. How about a big bowl of blubber? Carnivorous animals do not just eat a steak, they'll eat pretty much everything including organs, nerves, skin, eyeballs, etc which provides all the essential nutrients.

What would happen if you put sunscreen (or some form of spf) on plants/trees?
|
Plants have a waxy coating, cuticle, on their leaves which protect against the environment. The underside of the leaf opens at night and allows the leaf to respire. The plant also produces flavonols that protect against uv rays. Basically nothing will happen to the plant of you applied Sun block unless you applied it to the underside of the leaf, blocking the stroma that are required for release of O2 and intake of CO2Sunscreen is designed to block UV light specifically. It does not block visible light too well because you can still see yourself through it!', "I'm kinda curious, so I'm going to try this on my banana plants. Here's my best educated guess, though: Chlorophyll readily absorbs blue and red light. If sunscreen is transparent to these frequencies, then we won't see the leaves lose their green pigmentation. If sunscreen is opaque to red and blue light, though, you could possibly draw patterns on the leaf using the sunscreen, then see those patterns appear as yellow designs over the course of several days.

What do the dilation drops actually do to your eyes and why does it make your eyes sensitive to light?
|
Dilation drops open up your pupils, much like they would naturally do in the dark, to allow more light in. Helps the doctor see better when he's examining your eyes. Going outside while your pupils are dilated hurts because your pupils are already open and they can't retract like they would normally, so the light is POURING into your eyes. Tried to explain that as best as possible.

Seriously, what is the deal with airline food?
|
Airline food has to be prepared many hours in advance, then kept warm until it's needed. Hundreds of meals have to be kept in a very tiny space. It needs to be cooked on an industrial scale. It's not an easy task. Of course it could be done if they wanted to. But: > Why doesn't competition between airlines .. Airlines don't compete on the quality of food. When have you ever had a choice between two airlines, and chosen the one with the best food? Airlines compete on routes, on the times of their flights, and most importantly, on price.

What is the royal family’s job?
|
The Queen is the official head of the government and the ultimate authority by which it is operated. What good does any monarch provide for their country? In a practical sense she doesn't make many decisions but she can fire the Prime Minister if she wants and install someone else.CGP Grey has ~~two~~ three excellent videos on this. I suggest watching them. How much the Royal Family costs each year: _URL_0_ Brief history of the Royal Family: _URL_2_ EDIT: A third that may help clear some stuff up How to become the British Monarch: _URL_1_', "Well, for one, the monarch is still the head of state of the British government. Technically speaking the government's authority still comes from them the monarch and the monarch still speaks for the government. Second, the royal family owns a lot of land that they basically just let the government use. The value of this land far exceeds the value of the stipend they receive.The Sitting Monarch has a number of powers but they are rarely used independent of request of the Prime Minister. For a Law to actually be made by Parliament it must have the assent of the Monarch and denying assent is the equivalent of a Presidential veto. The Monarch is the technical Commander-In-Chief of all of the military though they have generals that functionally command things. It is under the authority of the Monarch that the Government forms and disbands. Etc. All the Royal family also function as high level diplomats and ambassadors for the country and receive training for this from childhood. And they own a lot of land, providing the homes and livelihood for thousands if not hundreds of thousands of people. Edit: Also their stipend is limited to 15% of the money generated by the Crown Estates, which is their property. They are not being paid by the British Taxpayer, they are being taxed at 85% for the money that is earned from those propertiesTechnically speaking, the Queen can disband the government at any time. In reality, if she tried that, the royal family will be disbanded and the UK will become a full democratic republic.

Why are livers prone to failure, when they can regrow themselves?
|
Livers aren't prone to fail over time due to alcohol, that is the wrong way to look at it. Livers valiantly extend the lives of people dead set on drinking themselves to death, holding out for as long as they can.It takes a relative fuckton of alcohol abuse to cause liver failure. You pretty much have to be drunk for most of your waking hours for years. Your liver will repair itself if you stop trying to kill itIn a situation like that, your liver is being damaged faster then it is regenerating, leading to a buildup of scar tissue eventually leading to liver failure.Probably a stupid question Are alcoholics less likely to get liver cancer? I'm not trying to justify anything, I swear. Just curious.

If phone numbers are public record why can't they be reverse searched?

> why do they charge to find out who's actually calling you? Because they *aren't* public record, so those companies need to buy the data from somewhere. Granted, most land lines will appear in the white pages/directories, but those you obviously do not need to pay to get info . _URL_0_ literally has a section that says "reverse phone lookup".

Periods.. Other than humans very few animals have them. What are the other mammals doing differently?
|
Basically humans aren't like most other species. In many other species the mother controls the bloodflow and nutrients to the embryo. That's why several animals can miscarry their pregnancy on demand to evade a predator. Human females do not control this nutrient exchange. Basically once an embryo attaches itself to a womb it's there to stay. The female prevents the unsuccessful embryos/unhealthy embryos from attaching themselves by discarding the womb monthly and starting over. [A fantastic TED video explaining]

How come car companies use glass that shatters into a million peices as a windshield and not something like plastic?
|
Windshields behave the way they do for safety. It's a feature, not a problem. In the case of an accident, you get either a large cracked bendy piece of windshield, or you get lots of little round fragments that can't cut you and kill you as you experience the crash. Large shards would be super dangerous. Plastic is softer than glass, so it would scratch and wear easily, as well as fading and yellowing over time, and broken plastic edges are nearly as sharp as normal glass edges, so it would be worse for safety and longevity.

Why use fans on heat sinks rather than a small thermoelectric generator feeding into the PSU?
|
Electricity is cheap and the amount you would get from most products that could utilize this is negligible. Small generators typically produce small voltages that would have to be converted, and large generators require large amounts of heat. No reason to bother when you can pay $0.10 for more electricity than the generator would produce in 6 months. Pros of having thermoelectric generator* Efficiency* Long term energy savings Cons* Production cost* Cost for consumer* Size* Higher potential for it to break* Added complexity

Why is the brain considered such a complex machine?
|
You are currently processing crystal clear images of your surroundings, focusing on this post, reading squiggles and translating them into sounds, connecting those sounds into words forming sentences with meaning while simultaneously feeling your hand on your mouse, smelling the air, hearing and interpreting sounds around you and doing about a million other things that are all controlled and fed back into your brain. And this is what you do absolutely effortlessly all the time, without even noticing. edit: grammarWe can build quantum computers because we built it bit by bit. We can invent these complex systems because we understand the fundamental basics and thus able to build huge systems. The brain is a complex machine as we do not know the basic principles of the system. Fundamentally all computers are simply calculators that interpret data differently. For example we do not see the world in the form of a wave , but we can teach the computer to interpret pictures as just RGB. The brain does not function as a calculator, it functions in a system of neurons that is far different from how a computer works. We tried to replicate the brain is something called a [neural network], but even that is not exactly how the brain works. We are slowing breaking down the parts of the brain responsible for certain tasks. However, the brain is like a concurrent system, thus it is hard to fit all the pieces together.Because it is the most complex thing we know of in the universe and have to know so much more to know than we do now before we can understand it. It's also living and not a machine really.

Why does my computer act 'groggy' when I start it up?
|
You might have a lot of background stuff like Steam, Skype, Spotify set to turn on when the computer goes up, you might wanna get CCleaner and check to see what starts up when you open your computerwindows does "disk caching" or something similar. it basically keeps track of which files you opened. and keeps some parts in the ram. and sometiems it will auto load things from the hard drive thinking hey he usuallt opens ie, so it loads ie before you double click the icon. so when you open a program and close it. the computer will save some info in ram to make the program open faster the second time. not that this is a huge difference but it can be noticaable. you could use hybernate instead of shut down to avoid some of the slowness of starting up, win 8 has hybrid shutdown. which is half hybernate half shutdown. my computer has problems with it so i do not use it.Everything you run needs to be loaded from disk into memory. This is slow since it needs to scan the hard drive for the data. Once a program is in memory, it doesnt need to do this when you run it again since its already there, except in the case you've used too much memory and it needed to get rid of something to make space.

Why does a small splash of vinegar result in perfect poached eggs, where the absence of vinegar results in stringy nonsense
|
The acid coagulates the proteins or whatever. Use fresh eggs, at least three or preferably four weeks from the use-by date. They hold together just fine and are a billion times nicer than something artificially held together with vinegar. I don't get poached eggs when I go out any more because they often reek of the stuff and have a tough skin on the white. Maybe they are using far more than they need, but it's awful.

You couldn't kill bacteria with 102° water, so why does your body heat up while you're sick?
|
The higher temperature boosts your body's immune system. It's more effective at higher temperatures. Of course, it's a fine balance, because above 105°, the heat starts causing serious brain damage.
|
Why don't things burn instantly?
|
It needs to heat up to the point where it has enough energy to combust. Also not everything is very flammableFor the instance you mention, it is because of an issue of needing to heat up. In the case of a log on a bonfire, it is because oxygen is being used too fast for the amount that is able to enter the area.

How are pranks where people dress up like police officers legal? Is this not covered by laws against "impersonating an officer"?
|
Impersonating an officer only applies when you attempt to use the power an officer has such as pulling over another car, detaining a person or trying to acquire goods or information. With a prank, no harm is done. It's revealed that is it a prank shortly after and good times are had by all.

How did the ancient civilizations map out coastlines?
|
They just estimated them, by sailing around and eyeballing distances. Take enough data and distances, and you can construct a decently accurate map of the coastline. Enough for navigation purposes, at leastHow ancient are we talking? Using a sextant and a compass you can get reasonably accurate positioning and you could slowly map out a series of precise points of the shoreline. Rough in the rest of it and you have a useful map. The more points you measure, the better the map.

How to implement the pentatonic scale (or any type of scale for that matter) over a simple I-IV-V progression.
|
A pentatonic scale fits nicely with all of those chords, so really you have the world at your fingertips when it comes to improvising over those chords using the pentatonic scale. When you want to hit a long note, try to chose one that is a note in the chord you are on at the moment, or maybe a 7th or a 9th . Otherwise just experiment, with that combination it will be hard for you to play something "wrong"', "There's not really an ELI5 for soloing. Just focus on tuneful bends, because they allow you to create notes that are out of key. These notes if you use them properly can help you create tension, and falling back to notes that are in key will cause resolution, which is all music is. Tension and resolution.

Why I can hear my dreams before I'm completely asleep?
|
Don't worry about your sanity, you're experiencing hypnagogia, a very common part of the transitional state between waking and sleep. People experience a wide range of sensory phenomena, such as: random noises ranging from buzzing to random speech to explosions; visual effects like bright flashes, colorful speckles, geometric shapes, or even fleeting vivid images; and some others like feelings of floating, bobbing, being misshapen, or a falling feeling followed by a sudden jerk. There are even more experiences that have been documented, but these are just a few of the more common ones.

Why does more electronic storage cost more?
|
In some cases, the manufacturing process is a lot more complex to make the item that has more storage, even if it isn't physically any bigger. In other cases, they make many storage devices, all with the higher amount of storage. Some of them are faulty, and can't store as much as they're supposed to, so they get re-configured as lower storage devices and sold off cheaper. In the case of the iPhone , the amount you pay for a bit of extra storage is far more than the cost of that extra storage. They charge this much purely because they know that some people will pay for it. At the end of the day, remember if you're asking "why does something cost X", the reason is usually because that's what people will pay for it, far more than because that's what it costs to make. But this is especially true in high-end devices like iPhones.You're partially paying for the research that went into making something that much data into something that is physically so small.

If a ninth planet exists and easily fits our readings and models, why haven't we found it yet?
|
How do we notice most of the planets in our solar system? We observe them because light hits them and bounces back for us to see. The further away they are the harder they are to see, you get to Saturn and you can't see anything with the naked eye. Further out you need binoculars or a telescope to see them. In fact Neptune was only discovered because we noticed Uranus wobbled a bit when it shouldn't. This wobble in fact lead us to think that there was a planet between Mercury and the Sun as Mercury also wobbled a bit funny. As it turned out there is no planet and this movement was explained by general relativity. Pluto isn't visible from Earth at all. Interesting fact, Pluto is so far away from the Sun that it hasn't completed a full orbit since its discovery in 1930.Now look at this proposed planet, it's orbit is MASSIVE compared to Neptune's. It's going to spend most of its time in darkness and without many objects for us to observe nearby we can't easily infer its presence.Planet X as predicted by the models is about as noticeable as a black cat, in a dark room, full of coal, at midnight. We rely entirely on reflected sunlight to *definitely* detect/"discover" planets, and there is *very* little of that at a distance where Planet X is expected to be found - it's dark and it's cold. Therefore, it's a ninja.

Why do our noses run when we are cold
|
You have small hairs inside your nose that are constantly doing the wave and pushing the snot back up your nose where it drains down your throat. These are cilia. When it's cold they say fuck this and quit working allowing gravity to do it's thing and make snot come out of your nose. Bonus fact: your body produces a cup of snot per day. _URL_0_", 'If your nose runs and your feet smell, you are built upside down.Two reasons: 1. When it's very cold, the cold air is also very dry. Your nose and sinus needs to constantly be moist. When you're breathing in dry cold air, the nose decides that it needs to be be more wet to counter act the dryness. Sometimes, it goes overboard and releases too much snot which leaks out. 2. Lower temperatures causes condensation which is why water droplets form on the side of a cold glass of water on a hot day. When you breathe in cold air, it's causing condensation of the warm moist air inside your nose and sinus, turning the water vapor into liquid water which runs out of your nose. Source: _URL_1_

Why is the standard format for a rock band a 4 piece drums/bass/guitar/vocal? How and why did that happen?
|
That comes from jazz music, where that combination of instruments is known as [the rhythm section]. In early New Orleans and Dixieland jazz , trumpet/clarinet/trombone would playing the melody and countermelodies, the guitar/piano/banjo would play chords, the tuba/bass would play the bassline, and the drum set would keep time. Jazz becomes very popular and 1935-1945 is known as the swing era or the "Big Band era." A [big band] typically has 12 to 25 musicians. Eventually the big band went out of style and some famous jazz soloists began playing with MUCH smaller groups that only consisted of the soloist and the rhythm section. Some Miles Davis albums only have 5 musicians trumpet, sax, piano, bass, and drums. Country music follows this same trend. In the 1930s, Gene Autry and Roy Rogers are singing cowboy songs with a huge big band behind them. By the late 1940s, folks like Hank Williams are playing with much smaller bands vocals, fiddle, rhythm guitar, slide guitar, bass, and drums. In the early 1950s, this style of country music evolves into rockabilly . *Edited to fix spelling mistake> This format is popular with new bands, as there are only two instruments that need tuning, the line-and-counterpoint formula prevalent with their material is easy to learn, four members are commonplace to work with, the roles are clearly defined and generally are: melody line, rhythm section with counterpoint melody, and vocals on top This sums it up perfectly, that configuration works incredibly well, along with being low maintenance. Those particular musical instruments are among the most commonly played making it much simpler to set up a band with this configuration.

Why hot drinks can be consumed comfortably, yet if any is split on the skin it can cause pain.

ever got a blowjob? if not, put a finger in your mouth. your mouth is much warmer / hotter than your finger. so of course, your mouth wont suffer as much as your finger from touching a hot drink. it's the other way around too: try to put an ice cube in your mouth and keep it there for more than 5 -10 seconds . you prob cant. and then try to put your finger on it. you probably can keep it there til it melts.

Why do so many countries view ex-president George W Bush as a war criminal?
|
Because he invaded a country the UN had not given permission to invade, based upon "intelligence" which wound up being entirely bogus. He then had hundreds of innocents "detained on suspicion" without trial, and many of them wound up being tortured, which is a war crime.A number of legal scholars have made arguments that various activities conducted by the US during its prosecution of the War on Terror may constitute war crimes and that a number of high-ranking officials including the ex-president himself could be held liable for those crimes. [The relevant wiki article details more.] However I would imagine that the majority of folk are unaware of these legal arguments and hold this view because they believe the invasion of Iraq to be unjust and the generally hawkish foreign policy of the Bush administration in general.There are a variety of crimes that were unambiguously comitted by the U.S. in the context of the war on terrorism: Under the ICC, the U.S. signed on to allow prosecution of war crimes that include "unlawful containment". Guantanamo imprisonment clearly is contrary to these laws. The ICC could elect to prosecute someone for these and GWB would be a good candidate. Additionally, this could extend to unlawful deportation and transfer. There are other more complex areas the ICC covers around "crimes against humanity" that might also apply, but those are more challenging.

What's up with the CERN drama, What are they trying to do?
|
What CERN drama? I can find nothing significant about CERN in the news. Are you sure you didn't find a five year old fear-mongering website about how "oh the LHC will destroy the wooooorrrrlldddd!!!!1!"', "It's business as usual. With the LHC, specifically, collisions are continuing at 13 TeV with 25 ns bunch spacing. This has been the case for the last few weeks. The [schedule] is public, the [morning meetings] are public, and the [online monitoring plots] are public. That doesn't stop certain people from completely making stuff up, presumably in order to draw views to their nutty YouTube videos.

Pensacola, FL has white sand and clear water. Corpus Christi, TX has brown sand and murky brown water. How is there such a huge difference on the same body of water?
|
Other posters are right in that the continental shelf of the western portion of the GOM is mostly mud/clay, meaning that most of the rivers dump muddy silt into the gulf, including the Mississippi River. The Gulf of Mexico churns counter clockwise bringing the muddy water down along the Texas coast. If you think Corpus Christi is brown, go to Galveston. Fun fact: depending on the wind, if you go a couple of miles offshore even in Galveston, you'll hit crystal blue water.The Texas coast is on a backwater eddy current from the Gulf Stream. That means our river silts get washed back in to shore. Further East, the lighter silts get picked up and washed away with the Gulf Stream, leaving only the heavier sand. _URL_0URL_1_Well, the rivers that run through Georgia and Florida have sandy bottoms and this keeps it clear. The Rivers that run through Texas as well as Alabama, Mississippi and Lousiana are mud or clay bottomed. This makes the water murky and dark.If you want clear water in TX, South Padre is your best bet. It's a killer drive, but is consistently nice every time I've been there.

why does it take so long (years even) to get a citizenship in a foreign country?
|
Because those countries want to limit the number of people who get the benefits of full citizenship. Making it take longer means taht fewer people will go through the process and the ones who do will really want it, or possibly be better in some way ', "Because that country has established a lot of paperwork to get in, has a huge backlog of applicants, only wants people that are very dedicated and willing to wait, or any of many many other things. It's all up to the government of the country, and they can decide many different things. Often though it's just paperwork getting done, or rather not getting done due to a huge umber of applications to deal with and quotas they can't exceed.

Why are bad words "bad"?
|
Detailed discussion of taboo topics like sex and dispelling of feces requires a specialized vocabulary. People are traditionally and unfortunately uncomfortable taboo topics , so people used this specialized vocabulary to shock and surprise people in normal conversation. That's where it starts and from whence the "badness" comes. People then take the "bad" words and transform them to something totally different, using them only for their "badness." "Fuck" or "fucking" can be a noun, verb, adjective, adverb, whatever you want it to be. It's kind of ridiculous. An interesting question is why do you reserve "bad" words for when you drop a bowling ball on your toe rather than just say "raccoon!"? Because it's cathartic. You need something to let that energy out, and socially acceptable words don't meet the bill for that for some reason. Asking an ELI5 about that would be a more difficult question for people to answerThere is a great video on this topic by VSauce: _URL_0_

How are free withdrawal ATM machines profitable?
|
ATMs are actually less costly for banks than withdrawals from human tellers. Remember when all ATMs were free Pepperidge Farm Remembers. EditPrior to 1988, there was no surcharging of cardholders by ATM owners in the U.S. In 1988 Valley Bank of Nevada began surcharging "foreign cardholders" for withdrawals at Valley Bank ATMs located in/near Las Vegas casinos.[29] Eventually, various regional ATM Networks, and ultimately the national networks, Plus and Cirrus, permitted ATM surcharging. Before 1996, foreign ATM fees averaged $1.01 USD nationally, according to a 2001 report from the US-based State Public Interest Research Group.[30] As banks and third parties realized the profit potential, they raised the fees.When an ATM has free withdrawals, it's for one of two reasons: The ATM is owned by the bank, and they offer free withdrawals to their customers at that ATM, orThe ATM is located in a retail location, and the fee is covered by the retailer in the hopes that some of the cash the machine has just dispensed will find its way into their cash register.The location pays for it, thus keeping you in the location and giving you a reason to go there in the first place.

Why can't I just hit the "Off" button on my computer rather than "Shut Down"

+ Pressing shut down Will terminate all system and user processes normally. Exiting processes have time to write logs and results in the primary memory. Some of it can be important, but 95% of the time you won't notice a difference, if you are a casual home user and not involved in servers or programing projects etc. It will also do what I describe in the next section + Pressing down the power button Gives enough time for the mechanical parts of your computer to power down safely. + Just pulling the plug Will cause the mechanical parts of your PC to lose power while still working, possibly damaging them or wearing them down (if they power down at an active position.An oversimplified but ELI5-quality analogy would be the difference between passing out and falling asleep in humans.

What causes the Reddit phenomenon of [deleted] and subsequent chain of deleted comments?
|
Typically when you see a ton of comments deleted it's because of a combination of user-removal and mod-removal. If two people get in an argument that either has nothing to do with the thread topic or becomes particularly nasty/abusive the mods will often delete the whole thing. Sometimes they'll just delete one party's comments if only that person was abusive or otherwise broke the rules of the sub. In other cases one user just decides they no longer want those comments as part of their "permanent record" and the other person decides that they don't need to leave their comments when the ones they were replying to are gone. As for karma, all of the karma received while the comments were active remains on the person's profile. Obviously, once the comments are removed/deleted voting is no longer possible on them.Yes, it's the mods. Some subreddits have very strict rules, and a comment thread might be in violation of these rules, so the mods delete it in its entirety.

How do modern aircraft "lose contact" with flight control?
|
"Lose contact" is a very vague phrase that could mean just about anything, but it means one thing for sure: lots of page views for advertising. Air France AF447 "lost contact" - flight was out of radar coverage as is totally normal for that part if the world. In between check-ins with air traffic, poor decisions allowed them to go from a minor instrument failure, to a full blown stall and then a crash in just 2 minutes. At no point during the sequence did the pilots attempt to contact air traffic, they were too busy or too confused. All the while, Air France did have a diagnostic system that reported maintenance issues and it also include location data. This is ultimately what was used to find it, but remember this wasn't in real time, there is no CSI/Jack Bauer type reviewing maintenance logs that are 99.999999% of the time totally routine. Do we have the technology to monitor the location of every plane in real time? Yes Is it actually installed and in use on planes? No In the long run, yes, I expect this is what will be common, but in the short run, satellite communication is just too expensive and the need is so rare, that it's not something that will happen overnightCommunication and location are different systems. The way we currently locate via radar has a fixed range of coverage per radar station. And communication is radio, also fixed com range, it is possible to lose one and not the other.

How are the marines 240 years old when America is only 239 years old?
|
The Revolutionary War started a year before the states formally declared independence. Originally the colonists\' view was that they were loyal subjects of the King of Britain , but Parliament had no special power over them because, among other things, they had no votes in Parliament. Most of the Founding Fathers originally believed the British would back down and there would be a peaceful renegotiation of the colonies\' role in the British Empire. So the "Continental Congress" had an Army, Marines, and a Navy in 1775 even though it wouldn't declare independence for another year.

Do All the Planets in our Solar System Spin and/or Orbit in the Same Direction? Why?
|
All planets in our solar system orbit in the same direction . This is becuase the planets formed from one big disk of dust and debris that was spinning counter clockwise. Once the matter in the cloud clumped up to form planets and moons, the planets all kept going in the same direction. It is also the direction that the sun spins in. Not all planets spin in the same direction. Venus and Uranus spin in a clockwise fashion, whereas the other 6 planets spin counter clockwise. Venus and Uranus probably do this because they were hit at very specific angles by big asteroids that spun them around. Another special thing about Uranus is that the tilt of the planet is 98 degrees (earth's tilt is about 23 degrees. This means that Uranus is actually laying on it's side compared to all the other planets.

If keeping your heart rate up is good for you during exercise, is the same true of watching scary movies, playing video games, or other passive heart rate boosters?
|
Heart rate increases due to exercise are healthier than heart rate increases due to terror . Terror-based heart rate increases are accompanied by a spike in adrenaline, which can be damaging to your heart over timeWhen you are afraid, anxious, or stressed, the main causes of passive heart rate increase, your body releases cortisol. [It has a lot of negative effects] including decreased immune function, weight gain, muscle break-down, and decreased thyroid activity. Source provided is one of many you can findExercise for your heart is good for maintaining health overall because it is participating in a physical activity, but any thing that causes a "passive" boost to your heart is caused by stress, which is a mental activity. There is many different forms of stress that are both positive and negative towards your health, and there are many reasons that causes it. It certainly depends on your initial reaction to certain events, e.g. falling in love, watching scary movies, looking at a pair of breasts for 10 minutes, playing multiplayer FPS video games , throwing a surprise party, or popping the question. Your reactions to these events, based on stress, good or bad, causes you to release a chemical called cortisol. Cortisol has both negative and positive values to what it does to your heart, and overall health. It depends on the events you are experiencing that causes such values to have either a good or bad impact on your heart rate . E.g. a cardiac arrest can develop from the release of cortisol in a stressful situation, like your friends scaring the living bejeebers out of you, or a frail old man.

What causes loose skin on some people after losing weight?
|
when you get fat, your skin stretches, there's almost no limit on how much the skin can stretch and you will get stretch marks if it stretches too fast. when you lose fat, it's hard for your skin to unstretch. so they are left with loose skin. of course the more weight they lose the more significant an issue this will be.

when baking, why can you not simply 2x, 3x, etc the recipe to increase the batch?
|
Baking is a very specific form of cooking that requires two things; humidity and temperature. When you're making your dough, you need it to raise and set. The size of your rolled/patted dough alters how it raises and sets. If you multiply a baking recipe, it could possibly affect the size of your rolled/patted dough, which affects the time, temperature, and humidity that it needs to raise and set.

Why do my veins look blue when my blood is red?
|
Oxygenated blood is the bright red you are familiar with, blood without oxygen is a darker red. Due to the way that light is absorbed by the skin and muscle between your veins and the surface, the dark red blood appears blue. Edit: any of the other answers stating that human blood is blue without oxygen are just incorrect. This is also one of those times that the search function should have been used, here is one result of search 'blood blue': _URL_0_ Googling 'why is my blood blue' yields these top results in case you want to read them: _URL_1_ _URL_3_ _URL_2_", 'Your veins are actually translucent. They appear blue because the fat under your skin has some unique light absorbing properties, as light penetrates your skin, most of the color spectrum is absorbed by the fat, leaving it a grayish blue appearence.

How does an insect's mind function relative to our own in terms of "thoughts," motivation, and instinct?
|
As far as brain development is concerned, humans have a shared heritage with other mammals, birds, reptiles, amphibians and even fish. There are structural similarities between the human brain and the brains of these species, and through various states of altered consciousness we can make an educated guess about the consciousness of these species. For example, the basal ganglia plays an important role when humans dream, and a reptile's brain by comparison consists of a structure similar to the basal ganglia, so we can make an educated guess about reptilian consciousness. Obviously the human basal ganglia has evolved some unique features, but the "driven" and "self-absorbed" sense of awareness experienced by humans when dreaming is likely similar to reptilian consciousness overall. Insects however do not have a common heritage with humans, at least not as far as brain development is concerned. Insects evolved from crustaceans, which in turn evolved from annelid worms . We can look at the amount of neurons contained in the insect brain, but we haven't really a good understanding or reference for the structures of the insect brain. As such, we can't really make educated guesses about insect consciousness, only speculation.Just because something has a complicated system build into it doesnt mean it must think. My computer can simulate an entire tropical island with multiple animals, but doesn't think. Thought only evolved because it is beneficial to have independent thought. Insects only need to follow, follow basic instructions and give basic signals to their fellow insects. With big numbers of stupid things doing work in group-form, you end up with something. Computers are again a good example. They are nothing more than gates that can go from on to off, 1 or 0, but put in large enough numbers and given proper connections , they can make amazing stuff. What made you think that ants must think? Trees do much more amazing things, they don't think and bacteria also perform a wide range of things, but that doesn't mean they think.

How do our toes, such a small part of our bodies, withstand our body weight with full stability without breaking?
|
They've evolved to be strong enough to. Bones are pretty darn strong compared to their size/weight. That, along with your muscles helping support them, can generally withstand a good bit of weight, assuming you're relatively healthy. And if you trained those muscles, you could do even more. Ballet dancers can jump around on their tippy toes, although their feet do tend to be kind of a mess as a result.

Why do we call bigotry towards homosexuals homophobia?
|
Homophobia is not a recognized clinical disorder the same way acrophobia is. It's first recorded use was in a NY Times article in the 80's. The wiki page on homophobia has a section mentioning the same semantic criticism that you do, with LGBT scholars suggesting terms such as homonegativity or sexual prejudice to replace the pseudo-scientific "phobia" suffix. Personally, I believe homophobia is a dated term that ties back to a time when it was believed that homosexuality and other non-heteronormative behavior was a mental disorderHomophobia IS the fear of homosexuals, and that fear can manifest itself as being hatred. Have you ever met an arachnophobe who screamed upon seeing a spider, shivered, and then said "Sorry, I hate spiders."Perhaps acrophobia is just bigotry and intolerance towards heights.You're confusing the suffix phobia with clinical phobias. They're not the same thing. The suffix phobia can also mean aversion, repulsion or hatred. For instance xenophobia, francophobia, hydrophobia, photophobia.

Why do scam websites that claim to sell "a revolutionary product" all look the same?
|
Because they work. Scam artists and lazy people see an idea that brings money for little work, and they emulate that idea. Why fix something that isnt broken, right? Similar idea to why there are a million different versions of Minecraft and Bejewelled. The people peddling these things aren't innovators. They don't desire to expand on previous formulas and improve the world. They just want quick cash, and the easiest way to do that is to do the exact same thing other people have done.

If women have a right to their own bodies, why is abortion legal, but prostitution illegal?
|
The straightforward answer to the legal question---at least in the U.S.---is that the government has a lot more power to regulate commercial activities done for entertainment than it has to regulate private medical decisions. The slightly less straightforward answer has to do with how courts look at the interests of the individual and of the state in these circumstances. At least when discussing the first trimester, the Supreme Court has said that the state doesn't really have an interest that overcomes the woman's control over her body, because of issues like privacy and the ambiguities of defining the start of life as a philosophical matter . This is not the case with prostitution, where the states interests are the same all the time, and where courts have said these interests can survive a challenge. Philosophically, of course, people debate this all the time. Plenty of people think both should be illegal. And many people believe both should be legal, or at the least that laws against prostitution should be restructured to punish those that use it to harm/dominate rather than those forced into or choosing that life. And, of course some people are divided. But that philosophical debate is only loosely related to why the law is presently the way it is.

Why, when looking at the reflection of my monitor in a glass of orange juice, do I see rainbows across the reflection?

Because your glass is curved. So it's going to curve the light passing through it and reflecting off of it ever so slightly. Bending light in such a manner produces a rainbow effect because the medium does not bend all the frequencies of light the by same amount.

how do people (Tom Petty Gaye family) win copyright battles over songs with loosely similar melodies? Haven't all the basic pop melodies been used a thousand times already?
|
Songs can be stylistically similar in a number of different ways, and it's when these add up that infringement becomes a problem. In other words, yes, it is inevitable that occasionally two songs will share a similar melody here and there. However, songs consist of more than just melodies: - Lyrical content - Beat/rhythm - Chord sequence - Choice of instrumentation/composition - Structure - Other stylistic decisions To name but a few. If two songs are similar in just one of these respects, then there probably isn't a problem. For example, most songs in the house music genre adopt a broadly similar structure . No-one is going to argue that this is plagiarism; it's just a stylistic feature of the genre. However, if I write a song that has similar lyrical content, chords and melodies to an existing track then suddenly it's going to raise some eyebrows. This was the crux of the Blurred Lines case. The main similarities are in the choice of instrumentation , the rhythm , and other stylistic decisions . Had Blurred Lines just used one of these elements, there probably wouldn't have been a case.

Why are warm showers very sedative and cold showers very stimulating?
|
The heat from a hot shower helps tightened or inflamed muscles relax and also promotes better blood flow and circulation. This, naturally, has a relaxing affect on the body. Cold water can stimulate oxygen intake via the physical shock from the temperature and can also increase heart rate, circulating blood flow. Cold water might also help relieve some muscle soreness.

why some game updates introduce more bugs
|
Think of computer code like a spider web - if you tug on one end of the web, the entire web moves slightly because it's all connected. Now, ideally, code should be modular, such that if you change this one piece over here, that other piece over there is completely unaffected. However, in the real world, it's quite common for code to get more interconnected than it really should be, to the point where if you make a change to this module over here, that other module over there, which should have *nothing* to do with your change, suddenly breaks or changes its behaviour in a subtle way. It's like trying to take scissors to a spider web and cut out just one part of it without causing the rest of the web to move - it's very, very delicate work.

Why do we forget dreams so fast?
|
They're not stored in long term memory. The reason for this is probably because there's no advantage to remembering them and remembering them would clog your memory up with crap.

How does 'dual-citizenship' work if one of the countries concerned doesn't have the provision of 'dual-citizenship'?
|
It doesn't. If you are a citizen of a country that doesn't allow you to hold multiple citizenships, when push comes to shove you may have to decide to give one of them up. Or you may lose your original citizenship automatically as soon as you acquire your new one. But it's not like, for example, the U.S. government won't let an Austrian citizen apply for U.S. citizenship because Austria doesn't allow them.You 'd be surprised at how disorganized this whole thing can be. It isn't like one country calls another and says "AngaragSandilya is ours now, so hands off." I know people who have gotten citizenship but just kept their documents from their homeland, and use that when they travel back there.It doesn't. In order to hold multiple citizenships all countries involved must accept and grant you the citizenships. If one country does not do this then you cannot hold multiple with that country as one of them, because the moment you get another you lose citizenship with them.

Why don't blood vessels sort of kink when we fold our knees/elbows?
|
1. The outside of each blood vessel is made of a material that has the right blend of firmness and flexibility. 2. Most blood vessels are surrounded by soft tissue that will yield first, or hard things that will protect them from some of the pressure. 3. The interior of blood vessels is pressurized by the action of the heart.They actually can get kinked off from bending but you probably wouldn't notice it that's to collateral circulation. Your body is designed in such a way that major vessels are in areas that don't bend enough to get kinked off and at the places they could get kinked off there are alternative paths that most likely would not be kind at the same time.They do actually. Every time you sit/kneel/lie in a bad position and an extremity "goes to sleep", it's because you 've kinked a few too many veins/arteries.

What is a Banana Republic? How is it related to Bananas?
|
Banana republic can either be: A fake republic, like the Nicaraguan republic in the late twentieth century. In this sense, banana is a connection to a centralized republic, like, int he hands of the few, in the case of Nicaragua, the hands of the banana business family. See the paradox? Or you can be referring to the nation and not to the system. In this case, we can use the southern central American countries, or the northern south American countries to explain. Historically, the government of these countries was controlled by the owners of the banana farms, these families were friends with the United States. So it was like "we give you bananas, and you give us other stuff so we can control the masses". And there you have it, a fake republic, dominated by the banana families. And, of course, there were several other banana companies that wanted to be the most powerful ones, but let's not complicate it. Here is an awesome video to explain it better and more organized: _URL_0_', "A banana republic is a politically unstable country whose economy depends on the export of one product in limited supply, such as bananas or minerals. A banana republic has social classes that are divided by wealth. These include a large, poor working class and a small ruling class made up of the businessmen, politicians, and the military. The ruling class controls and exploits the country's economy. [source]", 'Small politically unstable country economically dependent on the export of a single crop or mineral. Used to describe Honduras when it was highly dependent on the export of Bananas. These places are characterized by there being a small ruling class who are getting all the profits from the export, and a vast underclass who is used as labor/u/formerguest gives a good definition of the precise meaning. The term is often used more loosely, as a way to insult or dismiss a country. It means that country is small, backward, irrelevant, and has questionable or illegitimate leadership, particularly if it is Latin America.

How do tattoos stay in our skin even though we shed and peel away skin after sunburns?
|
Because we only shed and peel the upper layer of skin. The tattoo is a few layers deeper in and fairly well protected from peeling and shedding and loss of skin.

Why is Alcohol aged in Barrels?
|
As far as Bourbon The whiskey expands and contracts into the wood as it ages and with seasonal changes. This mellows the whiskey and imparts the oak flavor. The longer it ages the more mellow the flavor. This process creates longer molecular chains which aid in a better flavor. I drank some 23 year old bourbon yesterday that was so incredibly smooth as opposed to a 5 year whiskey that is very rough.

How is it that we've managed to make so many diverse variations of dogs, and would we be able to do this with any other animal on the same scale?
|
Dogs have a really weird and seemingly unique thing called a Slippery genome. We haven't discovered any other animals that have this yet, but it really helps in dog breeding. Dogs basically have backup genes that allow them to survive mutation much better than most animals. For example, if we bred lots of dogs with stubby legs together, we can produce some relatively healthy, stubby legged dogs. However, if we breed lots of stubby legged cats together, they get real unhealthy real fast. We need to breed in normal cats or else there are just too many birth defects and the breed becomes a dead end. But then the cats lose the stubby legs we want. We can come up with plenty of guesses as to why dogs have this "slippery genome" and other animals don't, but we haven't found any solid answers yet.

What does the parental advisory label do and does it prevent a child from buying CDs with that logo?
|
The advisory label is voluntary. There is no law or regulation that requires a retailer to not sell to a minor. It was created as a response to gangster rap from the 90s entering the mainstream. In contemporary times, I'm sure high school kids know more bad words than I do. And they probably know how to download whatever they want from sites I've never heard of. _URL_0_", 'I think it works like: * Little Timmy wants to buy CD with the label* Mom sees the label* "no son you can't have this" Or: * Little Timmy tries to buy CD with label* Clerk sees the label* "sorry little boy you can't have this"

Why do hear an echo like sound when we place a glass on our ear even though the room is quiet ?
|
Seashell resonance. The rushing sound that one hears is in fact the noise of the surrounding environment, resonating within the cavity of the shell. The same effect can be produced with any resonant cavity, such as an empty cup or even by simply cupping one's hand over one's ear. The similarity of the noise produced by the resonator to that of the oceans is due to the resemblance between ocean movements and airflow.The resonator is simply attenuating some frequencies of the ambient noise in the environment, including air flowing within the resonator and sound originating within the human body itself, more than others.The human ear picks up sounds made by the human body as well, including the sounds of blood flowing and muscles acting. These sounds are normally discarded by the brain; however, they become more obvious when louder external sounds are filtered out. This occlusion effect occurs with seashells, cups, or hands held over one's ears, and also with circumaural headphones, whose cups form a seal around the ear, raising the acoustic impedance to external sounds.]

Why do moths and other bugs like to crowd around light sources so much?
|
We think that moths use the moon/Sun for navigation. If you stand outside so that the moon is to your left, and walk keeping the moon to your left, you can keep a general heading. Moths developed this ability long, long before ANYTHING at night shined brightly other than the moon. So it gets confused when it sees a light. If you stand outside and keep a street light to your left, and then walk keeping it to your left, what happens is that you walk in circles around the light! That trick only works with the moon because it doesn't move as you walk around. PLUS, bright light makes a moth think it's daytime, and daytime for a moth is a time to sit still and hide. So the end result is that the moth thinks he's flying straight, but instead spirals around the light source. Once he gets close to it, he thinks it's daytime and tends to settle down until it's dark again. Hence moths circling lights and sticking around them for no good reason.

Why don't copyright laws affect China?
|
US copyright laws only really apply in the US. International copyright laws apply worldwide, but only to the extent to which countries wish to enforce them within their borders. China isn't making it a priority, and there isn't much the rest of the world can do to force them.

why does my Apple IPhone require that I have at least 4.5 GB of storage available in order to update?
|
The files you download in the update must be decompressed before being permanently installed. A 500 MB download could easily decompress into a couple of gigabytes or more.

Why is there such a small amount of steam games for mac?
|
It takes effort to build the game for the mac. Not as much effort as building it from scratch, but it does take a significant investment. It can also be different enough that you may want a specific team just for the mac work. For many companies that extra effort isn't worth the cost given the relatively small amount of mac gamers. Mac gamers are also often willing to either buy a gaming pc on top of their mac, or run windows on their mac via bootcamp. As such there is even less people who won't buy your game unless it has a mac version.
