Why do people bother keeping savings in banks/currencies which are potentially unstable?
|
[
"I see two reasons: 1. In most European countries you need a residence permit to open a bank account. In other words, you must live in the country where you want the bank account. Some countries, like Switzerland, allow foreigners to open bank accounts without a permit. However, the banking fees are high for such customers ( > 800$ per year). Unless people have substantial amounts of money ( > 100,000$) the fees will erase their savings. As it happens, many people in Ukraine are not very wealthy. 2. It is difficult. You need to go abroad, speak a foreign language, spend significant amount of time and money. Most don't bother."

Why does water freeze from top to bottom? Deep in the ocean it’s below freezing, why doesn’t it freeze?
|
[
"There are several reasons. The salt in the ocean lowers the temperature needed to make it freeze. Currents stop the ice from bonding, and if Ice did freeze, it is less dense and floats. But the main reason is the pressure, especially in deep water. To freeze, water needs to expand. Deep in the ocean, the pressure from the water stops it from being able to expand."
] |
[
"It depends on the shape of the blob of water, its temperature, and the time of day. Mars is very cold, the melting point of water is about as hot as it gets. Under most conditions the water will immediately start to freeze. However, the pressure is very low, about .6 kPa or 1/168^th of the pressure at sea level. At that pressure the boiling point is -40˚C so the surface will start to vaporize. If a solid crust forms around your blob, that will vaporize much more slowly that the liquid surface. Eventually it will all evaporate."

I've been reading up on nukes. Did the Nevada nuclear tests have nuclear winter? Why or why not?
|
[
"Nuclear Winter is not a local effect resulting from an atomic blast, but rather a hypothetical effect from lots of nukes going off. The theory is that the nukes would kick a lot of soot and dust up in to the air, blocking out the sun. The blocking out of the sun would result in lower temperatures since the sun can't heat up as much of the Earth anymore. Some of the effects are based on similar effects felt when a large volcano goes off. Mt. Pinatubo in the Philippines went off in the early 90's and we only saw a slight drop in temperature (1 degree F)."
] |
[
"Well, I know this is going to get buried but I'll answer as best I am able. One of the side effects is actually forest fires. I read a paper a while back that if Pakistan launched all their nukes and India launched just an equal number than the resulting forest fires would create enough Ash to create winter for four years. This is equal to the time period of what wiped out the dinosaurs. It's way more than 10, but hopefully helps you to understand some of the side effects of such a catastrophe."

How come cars are able to go up to 220 km/h but highways only allow speeds of up to 110 km/h. Wouldn't it be wiser to have cars max out at 110 km/h-ish and reduce the engine capabilities?
|
[
"How long do you want to take to accelerate? Merging onto the highway in a reasonable time takes far more power than maintaining a constant speed. There are plenty of 1.0 l cars for sale in Europe. They take about 17 +/- seconds to reach 100 kph, but they are very fuel efficient. No one would buy them here in the US because it would be frankly frightening to try to merge onto our freeways in a car that slow."

How does a two headed reptile/siamese twins work? How do they move their bodies assuming there are two brains?
|
[
"Typically each twin controls a different part of the body. Like the twin girls Brittany and Abigail Hensel. They give the appearance of being one body with two heads, though they have two of each organ above the waist. They have two arms, each controlling one. And from the waist down, they have one body, with each controlling one half. So each controls a leg, for example. There doesn't appear to be any part that both of their brains controls. So they coordinate with each other so that they can walk, but they each have their own body parts they use. In some cases of animals with two heads, only one head \"works\". The other head doesn't seem to have any reactions to stimuli so it's vestigial."

why aren't AK47's an "accurate" rifle
|
[
"1. AK-47's distance between the sight and post is very short which makes it so that for longer ranges, it is extremely difficult to line up an accurate shot as you are more likely to be misaligned with your eye to the sights. 2. It uses a relatively low velocity round, meaning it arcs more and spends more time to get to the target, making it deviate more from environmental conditions 3. Its feeding mechanism uses very large and heavy moving parts which reduces accuracy dramatically from recoil. 4. It has a more significant recoil upon firing due to its type of ammunition, making subsequent rounds less accurate. 5. It operates on a lot looser tolerances, while making it more reliable, also reduces its overall accuracy. 6. [Its gun barrel flexes more than other guns during recoil.](_URL_1_) Compare that with [this](_URL_2_), Or [this](_URL_0_) 7. The barrel isn't inline with the stock, making recoils want to push the gun upwards."

Why can I not remember what happens when I'm drunk?
|
[
"Memories enter the brain first as short term memory, that is then transformed into a long-term memory. This is evident because the majority of short-term memories that we experience are lost before they ever make it into what we will call \"long-term\" storage. When alcohol is consumed it affects your ability to take short-term memories and transform them into long-term memories. This is why you only may remember small bits and pieces of the night, these are the select short-term memories that were allowed to settle into long-term ones without the interruption of alcohol. As the level of alcohol drops, the number of memories that make it into \"long-term' storage increases."

Isn't the freshwater we have to work with just going in a cycle? How are we losing fresh water?
|
[
"When the water ends up in the oceans, it slows down the cycling a lot. Water in aquifers (the stores under the ground that we access when we use wells) and water on Earth's surface are the cheapest to use. We have been either polluting these (surface) or using them too fast for new water to filter in. We have also allowed a lot of water to go to the ocean(storm water runoff from developed areas) , rather than slowly go into the aquifers through the ground. So the result is we are using aquifer water faster than they are getting refilled. When that water is depleted, all water will become more expensive. We will still have it, but it will either be salty, polluted, or far from where it needs to be, and all of the fixes for this cost money. Sorry if this isn't too coherent, I haven't finished my first cup of coffee for the day."

Why metal at room temperature feels cold while, say, fabric at room temperature doesn't
|

Please correct me if I am wrong or missing some details."

Why are swearing words related to genitals and/or sexuality?
|
[
"Swear words come from things we consider taboo or distasteful. In English-speaking society, we have a lot of taboos surrounding sex, even in this day and age. We also put a very high level of importance on hygiene, so words relating to waste and where they come from are also taboo. Certain words automatically make your brain think of a subject in a more intense way than others. A colloquial term vs a scientific one. This is true for pretty much anything, even if it isn't a swearword -- sweat vs perspiration, for example. When it's a topic that's taboo, that word becomes a swear. When it isn't, it moves back into innocuous territory."
] |
[
"Most of the 4-letter taboo words in English come from Germanic languages and were considered crude to the Romance language (French, Latin) used by the aristocracy, as the last poster explained. In some languages the harshest swears are phrases that invoke religious figures like Jesus and Mary. Nearly every society has words that are considered taboo and used to emphasize, ridicule, or express disbelief. I read once in a book about language that if we allow 'swear words' to become acceptable we will invariably invent new ones."

So use your dominant hand for entry and place the other hand palm down thumb towards you, gently but firmly across the lower pelvis.

Why do we hear static from radios and TV's when there's nothing being broadcast? Shouldn't we just hear silence?
|
[
"Because there isn't nothing there. Every spectrum is full of random noise from stars, radioactive decay, all sorts of things like that. It's just terrestrial broadcasts are so much stronger that it overwhelms the random noise. This is why when you start reaching the edge of the coverage area for the station you're listening to, it starts getting more and more static-ey and doesn't just go from \"fine\" to \"nothing.\""
] |
[
"It depends on whose signal is stronger. If you put a radio right next to your broadcasting antenna, it'd probably pick up only your broadcast because it'd be a lot stronger. If you put a radio far away from your antenna, such that your broadcast was comparatively weak, then they'd pick up the \"main\" radio station at that frequency. If the two were somewhat balanced - i.e. someone was positioned such that the signal from your broadcast and the signal from the main radio station are about equally strong, then they'd definitely get a lot of interference. It wouldn't be static, they'd actually hear both radio signals mixed together. They'd be able to pick out bits of both sometimes, and other times they'd indeed collide to produce noise."

Also, the situation of getting soaked to the skin is unusual for the dog, perhaps stressful, because their undercoat is an important protection to them. To get this undercoat wet \"against their will\" so to speak, while being restrained, can make them stress. These things can combine to overexcite the dog. To discharge this overexcitement, the dog may go apeshit - running, shaking water off, frenzied actions. In short, blowing off steam."

What was the warsaw uprising
|
[
"Warsaw was under Nazi rule. People didn't like that, especially the Jews living in the ghetto. People were purposely starved, killed in the streets. The Polish Underground State was formed - a resistance paramilitary which was made of several groups that wanted to liberate Poland (and save Jews). Some folks with radios learned that the Red Army was coming. And the Reds hate the Nazis. And the Polish Resistance thought \"Hey! If we fight the Nazis from within - and the Reds help out - we'll totally fuck the Nazi shit up!\" The Resistance started fighting - but the Red Army never came to help them. Those dudes camped outside the city. The Poles fought the Nazis for two months, much of the city was in ashes, and Churchill was all like \"HEY STALIN, COME HELP OUR POLISH ALLIES!\" and Stalin was kinda like, \"I don't want to risk my dudes quite yet..\" That's the Warsaw Uprising."

And as a business it's pretty profitable. The overhead's low enough that theoretically anyone with a few thousand dollars can get started. To see how it works, watch the doc *Hot Girls Wanted* on Netflix. A majority of the porn you see online is just a few entrepreneurs with a bit of investment money, some basic camera equipment and film editing skills and a house/hotel room to film in. The ad revenue and paid subscriptions quickly give a return on investment."

Why do DVDs in widescreen format play with black bars on top and bottom on my widescreen TV
|
[
"Just because it's \"widescreen\" doesn't mean that it's the same exact aspect ratio as your TV. A movie with black bars on the top and bottom was filmed in an aspect ration that's even wider than your widescreen TV. Look [here](_URL_1_). Most widescreen TV's are 16:9 (the third from the bottom on that page), and many movies are filmed in 2.39:1 (the one on the very bottom). Clearly, you cannot shrink the bottom one to fit on a 16:9 screen without having bars at the top and bottom with no picture. Well, you can if you can tolerate a distorted, squished picture. Another option is to use [Pan and Scan](_URL_0_), which gets rid of the black bars at the expense of cutting off the sides of the picture."

How do spammers spoof a cell phone number to make scam calls?
|
[
"When you make an outbound call, the calling system gives the phone system the caller ID information. The reason this can be (legitimately) different from the actual call is for example a business that has both direct lines to each extension and a main line. An employee calling out would show up with the main line as their caller ID so that if the person calls back they get the main number (this way you’re not giving out the direct number unless you needed to). The spammers take advantage of this system to spoof a number in the caller ID. The phone company could counter this by comparing the caller ID info with a number you legitimately own, but they get a lot of money for all these spam calls and they’re not incentivized enough to change how they do things."
] |
[
"Often times, the account that appears to be sending the message did not actually send it. The “from” address is basically being forged. In internet parlance this is called “email spoofing.” There is phone spoofing too (fake caller ID information) which is a freaking epidemic in the U.S. these days. The person whose email/number is being spoofed can’t do anything to stop it."

How have wolves impacted Yellowstone?
|
[
"This is just one example. More grazing animals means less vegetation for other animals to use as a home or shelter from prey. They also took vegetation away from the river banks causing more erosion. (The roots held the soil in place) The reintroduction of wolves stopped that and kept the grazing animal population in check, allowing the vegetation to grow back."
] |
[
"The former ranges refers to native elk. The native elk population of Pennsylvania was eradicated in the 1870's. The current elk population in Pennsylvania is descended from Yellowstone Elk that were brought to PA by the state Game Commission in 1913 and 1915. This was done to provide game to hunt, replenish an Elk population in PA for wildlife benefits, and to create a population of Yellowstone Elk outside of the dangers of the west (where disease and overhunting were a problem). Because they were transplanted and not from an original wild population native to the region, they are not counted on that map."

What is the difference between a CEO and the President of a company?
|
[
"\"President\" is a term that is often based on the law of the place where the company is created. For example in the United States, most states require that a corporation have a person with the title President. That title carries with it some legal obligations that tie the individual to the actions of the company. Most jurisdictions don't define or require anyone to hold the title \"Chief Executive Officer\". Depending on the size of the entity, the President and the CEO may be the same person. Large entities may be comprised of several smaller companies, each with a legally required \"President\", who may report to the CEO at the top of the organizational structure. Some companies may separate the two titles for internal organizational reasons, for historical reasons, or because someone thinks it's clever. It is rare for a company to have a CEO who reports to a President. CEO has become the de facto title for \"the highest level of the executive ladder\", but that's arbitrary and fashion could change."

How do American football have bruised lungs without also having broken ribs? Isn't that the point of ribs?

"This is actually one of the major issues with American football. The padding protects from the blunt hit and spreads out the impact so you aren't taking a lot of force to a particular place on your body, but your body is still being shoved really hard as a whole. This means the force is spread out and absorbed a bit so your skeleton isn't taking such a direct impact, but since a body at rest tends to stay at rest, when you get hit, your organs like to stay where they are as your skeleton is forced to move and they bang around inside their cage."

To really prevent plaque, brush your teeth after meals if you can.

"The real numbers are all the numbers you grew up working with - 1,2,3,4, 4.5, 1/3, 1.2345, -27, 3.1415... and so on. When you limit yourself to the real numbers, the square root of -1 is undefined - there's just no possible number it can be. To get around this, mathematicians defined **i** as the square root of -1. Giving you `i * i = -1`. Imaginary numbers are any real number multiplied by **i** : i, 2i, 3i, 4i, 4.5i, i/3, 1.2345\\*i, -27i, 3.1415...\\*i and so on. Then you also have the *complex numbers* which are made up of *both* real & imaginary parts - things like `(2.5 + 3i)`. Really, anything of the form `(a + bi)` where a & b are real numbers."

How odds work if everything is random?
|
[
"Odds basically tell you that if the exact same situation were to occur an infinite number of times, what portion of those times would lead to that specific result. e.g. If you have the Ace of Hearts, King of Hearts, Queen of Hearts and Jack of Hearts in your hand and 48 shuffled cards in front of you, there is a 1 in 48 chance you will end up with a 10 of hearts for a Royal Flush. There is no way of guessing which card will come up next, but if you shuffled that deck drew a card (made note of which card it was, replaced it and repeat) millions of times, you would get the Royal Flush 1/48 of the time. A pro would make that bet if it pays better than 48 times their money. They will only win 1/48 of the time, but if they get the chance to make that bet many many times in their lives, the rare win will make up for the cost of the losses."

How my wife and kids would go about inheriting things that are only in my name like bank accounts, house, ect..
|
[
"By default, after you die, everything will go to your legal next of kin. That person (or persons) is defined in this order, and if you don't have a living member of each group, it passes to the next one down: Spouse Children Parents Siblings I believe that next comes grandkids, then grandparents, but don't quote me on that. So if you don't have a spouse, but you have 3 kids and 2 parents living, your property would be split between your kids by default. And they'd inherit debts and things as well. A will exists to change these defaults. Say you have a spouse, but you still want to make sure that certain things go to your kids, your will would enumerate \"Hey, my kids get this, this and this, and my spouse gets whatever I didn't list.\""
] |
[
"There is an order of precedence for this. I believe it goes: Children -- > Parents -- > Siblings -- > Extended Family -- > The State. They inherit the money/possessions minus any debts you have. So if you have $10,000 in a bank account and a $5,000 dollar loan, they would get $5,000. No living relatives - The Government gets your stuff Debts Wiped? - Debts die with you What happens to your stuff? - Its sold or disposed off depending on what it is Money in the bank? - It goes to whoever is getting your stuff, and yes it would be used to pay off any debts. Absolutely nothing would stop you from doing that. They would lay claims on whatever you left behind but if you aren't leaving much behind anyway you just bilked them."

Are calories just calories? Is it the same if you get a calorie from a fizzy drink or a piece of fruit or a slice of potato or a bit of cheese?

"A calorie is a physical measure of energy - specifically, the amount of energy needed to heat one metric mililitre of water by one degree Celsius. Energy in food intake is also measured in this way, though the terms kilocalorie and calorie are often used interchangably, which can cause confusion. But yes, no matter where it comes from, one calorie always represents the exact same amount of energy. However, a difference you *can* make is that some foods will allow the energy that is within them to be absorbed more efficiently or more quickly, which can lead to varying results. (Edit courtesy of Neo6874: One calorie heats one millilitre by one degree Celsius. One kilocalorie heats one litre by one degree Celsius.)"

Why is it that lakes/ponds around the world have fairly similar fish, instead of them each having their own unique species of fish like land ecosystems do for animals?

"The water in the lake came from somewhere. Most lakes are fed by rivers and streams, or were originally parts of a river network as is the case with [oxbow lakes.](_URL_0_) A lake that was completely isolated from any other sources of water would eventually see evolutionary divergence if it had unique stressors, but there aren't many, if any, lakes like that, at least aboveground. Also a lot of lake and river fisheries are stocked by humans. Like, you'll find largemouth bass in a lot of fisheries around the world, it's especially popular in Japan, but largemouth bass are only native to North America. They were artificially introduced to fisheries elsewhere."

"South America and Australia simply have more species of animals. More species means a wide variety and so you're more likely to find dangerous ones. There's also plenty of completely harmless animals in these places but they just don't make the news as much. As to why these regions have more species there are many reasons but most people agree that the ice ages played a part. Europe and North America were cold and inhospitable for thousands of years, whereas the areas around the equator were fine, giving life a much better environment to evolve into the plethora of species we see today."

Instead of seeing one continuous picture, you'll see a lot of dots of each color. That's basically how Mantis Shrimp see."

how does your brain produce a coloured image through staring at a negative?
|
[
"Your eye sensors tire after a short while viewing a static image. In this example they're giving you a fixed point to focus on so that the image stays positioned in the same place on your retina. Notice how her lips are green in the negative. Staring at that wears our your green sensor there. Then, when you switch to look at white (which contains red, green and blue) your eye's red sensors work but the green, temporarily, do not. So you see red lips."

Why are most passwords hidden on-screen by default when you type them, but WIFI passwords are not?
|
[
"Most on screen passwords are hidden in-case you have any shoulder surfers(people watching you type over your shoulder). WiFi passwords give you the option to either hide or show, in my opinion as WiFi passwords are normally longer than other account passwords they can be hard to make sure your typing correctly without seeing it"
] |
[
"It's a security feature to make sure that you're typing your password into the real login screen, and the last person to use the machine didn't leave it running a fake login screen to collect people's passwords. For historical reasons, the Ctrl-Alt-Del combination can only be read by Windows, it will never pass that keypress to any other program (in the days of DOS, it was used to reboot the computer). Therefore, if you press Ctrl-Alt-Del and something happens, you know you're dealing with the real Windows screen. Actually it's not quite a guarantee now, since it's possible to give Windows some custom code to handle the login process so that things like fingerprint authentication can work. Installing a malicious version of that code to steal passwords would be much harder than just faking the whole login screen, though."

Why does time use the number 60?

"60 is easy to divide cleanly in multiple ways, and a number based on 60, such as the number of degrees in a circle, can be divided yet more ways. 60 can be divided by 1,2,3,4,5,6,10,12,15,20,30 and itself. This provides many easy-to-reckon, useful fractions. In the days before pocket calculators, slide rules, Napier's Bones, etc. this made life simpler."

Why does water taste bitter after eating pineapples?

"When the water hits your taste buds, they are stimulated a little. The problem is they have been overloaded with sugar and acid, thus they are temporarily unable to *report* sugar and acid at that moment.

How do cars calculate speed and preview it on the speedometer?
|
[
"**NOT ELI5** The car's driveshaft also powers a *speedometer cable*, which spins a magnet around at the same speed inside the *speed cup*. This magnet rotates continually in an equal direction. This spinning creates a fluctuating magnetic field. The laws of electromagnetism dictate that a current must therefore flow inside this cup. This current causes the speed cup to also rotate. It attempts to catch up with the speed of the magnet. a *hairspring* stops this, so it only rotates a little. This small motion moves the dial on the speedometer a little. The stronger the current, the faster the cup rotates, the further the speedometer's dial moves. & nbsp; **ELI5** The driveshaft powers a speedometer cable, which leads to a magnet rotating inside a cup. A current is generated, and the cup tries to rotate also. A spring limits this, moving the dial. More current = more speed = dial moves further."
] |
[
"Speedometers measure the speed of a vehicle by using a magnet attached to the vehicle's transmission through a series of gears. As this magnet spins it interacts with the speedometer needle and pulls it a certain amount depending on the speed of rotation of the transmission. speedometers must be calibrated so that the amount the needle is pulled accurately reflects the speed of the vehicle and the difference in speed you describe is most likely due to either your's or your girlfriend's speedometer being calibrated incorrectly. Tire diameter can affect the speed of your vehicle without changing the measure speed on the speedometer, so if you have much larger tires and in particular if these were not the original size of tires of the vehicle this could cause the reading on the speedometer to be incorrect For completeness: Electronic speedometers work in a similar way, just the reading is transmitted to the speedometer by wiring from the transmission instead of mechanical gears"

What prevents DNA from getting tangled?

"Proteins! There are *many, many* proteins in your body that have a specific job of keeping your DNA tangled/condensed the perfect amount. There are topoisomerases, a family of proteins, that specifically twist/untwist your DNA to introduce/remove \"supercoils\" (like what would happn when you twist an elastic band) to condense it or expand it. There are some proteins like histones to which the DNA will almost always be attached. The histones kind of serve as a backbone for the DNA; a place for the DNA to organize itself. Of course, this is just the very basic level of proteins. There are many more proteins and ways to organize DNA. It's always proteins!"

why child support is based on income rather than what a child would need monthly.

It is also partially based on the number of children and their age, the cost of basic living expenses and school in that general area, and whether or not any special needs are present.

That doesn't mean those expenses don't occur though."

[
"Nothing is a perfect mirror. The material still ends up absorbing some of the light. Eventually it would all get absorbed."

[
"The difference is this: For you to see light, the light has to be strong enough to reach your eye and produce a reaction there. For it to illuminate you, it would have to reach you, scatter off you, reach someone else's eye, and produce a reaction there. During the scattering, the light is spread out more, so it becomes fainter. Let's look at the case of a laser pointer. Point the laser at the wall, and the scattered light is comfortably visible. Point it at your eye, and you're looking at serious eye damage."

Why is Reddit valued at "only" ~$1.8 billion, when less popular sites (e.g. Twitter) are worth many times more?

"Reddit isn't publicly traded (there hasn't been an IPO yet), so speculation can't inflate the value of the company like Twitter or Tesla. A company is basically worth how much people are willing to pay for shares of it, but you can't buy shares in Reddit yet. It's also not profitable, yet, which doesn't help."
] |
[
"On an actuarial basis, companies are typically valued at 1.5-5x revenue. A billion dollar company likely makes a quarter to a half billion in revenues. Keep in mind, even small startups need $1-10million to get off the ground these days, and it's not uncommon for a connected entrepreneur to dump $50-100 million of venture capital in. These values get very big, very quickly. Every startup isn't worth billions, VERY FAR from it. Most fail, and the rest are barely worth their startup cost. The few that make the news are the cream-of-the-crop success stories, the big acquisitions. Amazon buys Twitch, Facebook buys Oculus, Google buys Youtube, etc. There are dozens every day that you would never see. Twitter acquired Mitro this month, Apple acquired BookLamp a month ago, Yahoo acquired ClarityRay 10 days ago, Square acquired Caviar 3 weeks ago.

How can electric motors for cars be small enough to fit into a car and relatively cheap while industrial electric motors with similar power and torque are the size of a kitchen and cost more than an electric car?
|
[
"Industrial electric motors are meant to be run nearly 24/7 at higher loads and don't have to be portable, so size isn't usually a factor as much as keeping them cool, so they're built to shed excess heat better, and more surface are = more heat that can be transferred away. on the other hand for cars, weight and size are bigger factors, and the motors in them will never be run full power all the time, so more effort is put into them to keep them smaller. Heat dissipation isn't as much of a problem either in a car as you can use the cars air flow to help keep things cool, whereas industrial motors don't usually sit in well ventilated areas."
] |
[
"Because electrically, one huge single cell battery would be extremely inefficient. Spreading the load over multiple cells is how we make batteries work for more cycles, especially longer cycles that electric cars need. If we used a giant single cell battery in something like a car, it would run very hot, be enormously heavy, probably have a range of 10 miles, and the battery would probably need to be replaced after 100 cycles. Electric vehicles demand a specific, high voltage, with the longest deep cycle possible. Multiple small batteries is the safest and most efficient way we can do that with the technology we have. 18650s currently are the cheapest and most reliable way we can do that on a mass scale. tl;dr it's much more efficient to run multiple cells in series than less batteries in parallel (or one single cell)."

"people use their eyes to communicate their level of comfort/aggression/submission with one another. shades will remove this information and allow others to fill in the blanks. for example, you might be avoiding eye contact, but because of your sunglasses this does not register with people and you seem undeservingly \"cool\""

What is the difference between quality sushi and regular sushi?
|
[
"Fresh vs. Frozen - was it alive this morning? The Chef's reputation and experience - you're buying his car! The ambience isn't free, if you're having sushi at a Chinese buffet, it's mostly fake crab and Thai illegal immigrants doing the work. The exact kind of fish! You're not going to find supermarket fish at the Sushi-is-us hole in the wall. If you want the whole range of selection, you need the real Sushi Bar."
] |
[
"It's not that hard to cook sushi. But have you tried good sushi and regular sushi? It's still a big difference in flavor. The way the rice is cooked requires a lot of experience to \"hit the perfect spot\". The same applies to some fried parts, sauce / wasabi. etc. It's required a lot of practice. Also it's still has some purist traces that sushi chefs want to pass on, raising the standards up."

Why do American cities often have to take large public transport projects such as light rail and metro system to the voters but don't have to do the same for massive highway and road construction?
|
[
"Large road projects usually exist to keep the existing road network running, or to improve its relation to the rest of the city. Bridges need to be retrofitted, underpasses capped, tarmac replaced. They may be big projects, but they're really necessary to keep the system functioning like it is. A major public transportation network is an entirely new investment. If you don't do it, you don't it--there's no downside other than that you don't have the network. A comparable project would be the construction of an entirely new highway link (or in some cities, the removal of major highways), which is rare and nowadays often put to voters as well. Of note is that many major highway projects were initiated in a time when referendums for transportation were not as common."
] |
[
"In the Northeast, for instance, many decades old bridges/overpasses could now be far too small because cars/standards have gotten bigger/higher, while redoing the hundreds of thousands of overpasses/bridges would cost trillions of dollars, while the transportation infrastructure already needs billions to stay where it is right now. That and standards vary state to state, even county to county or city to city. New York City bridges and overpasses are many different styles, and it isn't likely to change for sheer effort and cost."

How come bluetooth is so much slower than Wi-Fi?
|
[
"Bluetooth is designed to be short-range very low-power for small portable equipment. Part of the power-savings of Bluetooth come from diminished bandwidth (just as much as the weaker signal). One could speed up Bluetooth to Wi-Fi speeds, but then it would defeat the purpose of BT's major design feature. If you're looking for something that works like plunging a cable between devices but has Wi-Fi speeds, you might like wireless USB: _URL_0_"

[
"They can, My in-laws don't have internet in their house, they just have a hotspot device that they turn on and off when they need internet. But generally, wi-fi is faster and more reliable than cellular data. Even 4G LTE is not as fast as AC internet speeds."

How does the ISS avoid damage from solar wind's if it is always in constant orbit?
|
[
"The ISS orbits beneath the protective shield created by the earth's magnetism. The bulk of the solar wind is deflected away from earth by the earth's magnetic field."
] |
[
"It's a magnetic cloud that prevents most charged particles of the solar wind from hitting Earth. Apollo flights went through it at one of it's thinner spots, while going pretty fast. Of course the spaceship was large, much larger than the particles of solar wind."

Why do we tear up when we yawn
|
[
"Not 100% sure if this is the correct answer, but the act of yawning presses against the glands which produce tears. These glands are like a sac, so pressing against these sacs make the tear flow regardless of if you need it or not"

With the Separation of Pangea, how come we didn't evolve into several different species?
|
[
"We weren't around back then. The continents were already in their present form when humans evolved (in Africa, almost certainly)."

[
"The same reason why Kangaroos only exist naturally in Australia. they evolved on the American Continents after they separated from the other landmasses."
