How do all of these companies that claim to "consolidate your debt" work?
|
[
"It's a loan. They make interest. Since pretty much every debt has interest, they can charge a little more interest (since they tend to be scammy), and sometimes even cut the amount owed. Even with a high but not completely unreasonable interest rate, can still be lower than credit card interest rates, or old loans issued in times of historically higher rates. If most of the debt is high interest, you come out owing less. But, as you say, the selling point often isn't *lower* payments, rather *easier* payments. You owe one company a bunch of money, rather than many companies some money, and you pay for the privilege of having to buy less envelopes and checks (and/or being a sucker, or to postpone financial distress)."

"Bad credit can be very real indication you did not manage your finances and debt well. If i'm hiring someone to manage my company's money, and you can't handle your own finances, why should I trust you to handle mine?"

how do the bacteria in probiotic yogurt survive stomach acid and populate the intestines?
|
[
"Most of them don't but a few will get through and once they are within the gut they will start multiplying if they can find a niche there. The intestine already has a huge bacterial population and they have a habit of killing their neighbours which is why probiotic* yoghurt etc needs to be taken repeatedly to establish a viable population. * probiotic really refers to certain nutrients that specifically help bacterial growth rather than the bacteria themselves but the term has been co-opted to mean both."
] |
[
"Antibiotics and probiotics will actually cancel each other out that's why all probiotics have a warning on them to take them 2-3 hours after you've taken antibiotics. If you are asking why they can be taken in the same day if you give the antibiotics enough time to make it out of your stomach and into your blood stream they are no longer present in the stomach or small intestine to affect the pro biotics."

The chemical reactions that go on in my cell phone battery and how to make it last longer
|
[
"It's like a really big game of red rover. When the battery is brand new all the kids line up on one side of a football field. This is the + team (Li). When you use the battery kids run across the field to the other side to join the - team (ion). Some kids can't keep running from team to team so they stop in the middle, and play with the grass, or do whatever. Each time more kids can't run the whole way. Till eventually only the fast kids are left. Thus - team fills up faster, and so does your + team. Meaning the battery life is much shorter. Now heres some crayons. I don't like the phrase, \"lost it's elements.\" More like the elements don't play the battery game anymore."

"Lemons are acidic, and by poking them with electrodes of the right material, you can make a battery. You can charge your phone from a battery.

It's hard, but science project hard, not rocket to the Moon hard. It's not a useful way to charge your phone, but nothing on Facebook is necessarily useful."

Why couldn't T-Rex have been both predatory AND scavenging?

[
"Language like this is usually used for disambiguation. It *can* lead to confusion in the process, but mostly it's to try and *avoid* it. There's often some overlap between behaviour. In fact, *most* carnivores will scavenge when given the chance. There just wasn't much hard evidence of this specifically existing for T-Rex, and it's easier to classify animals in 'either / or' groups, than catering to blurry, movable lines. Bear in mind, this find **doesn't** constitute proof, either (and the blogspot article seems a bit biased). There could be numerous explanations for it, not all of which imply active hunting."

The purpose of the "indefinite detention" aspect of the National Defense Authorization Act?
|
[
"The biggest reason that I hear cited is that terrorism is very difficult to fight. A lot of times, the government has to act based on hearsay in order to prevent terrorism, and it's difficult because all the cards are stacked on the terrorists' side; Before NDAA the government couldn't detain potential terrorists, it couldn't legally search their property or (until after 911) wiretap them... someone could be getting all of the materials together for a roadside bomb or something, and we'd be powerless to do anything about it until after a lengthy court case, which requires a ton of evidence and time to get a conviction for, and still leaves the person out in society and free if they can afford bail. As a result, the government seeks new ways to fight what they see as a more difficult battle than one outside our borders. I don't agree with the NDAA at all, but that's the argument that i've heard, and i don't think it's necessarily a stupid argument either."

The time travel paradox (or the hitler's death paradox)
|
[
"You cannot time travel, it causes a paradox. In particular it would violate causality as in if you killed Hitler then he would never rise to the point where you need to go back and kill him, which means since you do not go back and kill him, he rises to the point you need to go back and kill him."
] |
[
"Well, as time travel into the past is (as far as we know) not possible and thus entirely fictional, what happens depends on the whims of the person writing the story. There are loads of solutions to your question, depending on whether you want to use the many-worlds theorem (in which case you probably travelled to a different alternate universe each time, thus no paradox) or a single universe with a contiguous timeline, in which case you have to determine whether time \"heals\" paradox (paradox is impossible) or if causality can be violated. There are stories based around all of these fantastical theories."

How floating-point numbers work
|
[
"Floating point numbers are essentially scientific notation. Like when you have a number written as 5.972 * 10^24 . Written in this way, the number consists of several parts. In this example, 5.927 is called the significand, 10 is the base, and 24 is the exponent. Floating point numbers use a set number of digits to represent the significand and the exponent. Since they work in binary, the base is always 2, so it doesn't need to store that. A 32 bit floating point number uses 8 bits for the exponent, 23 bits for the significand and the final bit is used to tell if it is positive or negative. One point about using binary in this way is that there's actually no need to store the number that comes before the \"point\". It can only be 1, because if it was 0 you would have shifted the point across a digit."
] |
[
"The simple answer is that a double sacrifices precision for a larger range, and a long sacrifices range in favor of exact precision. To put it more clearly, a long has a full 64 bits of precision and can *precisely* represent any number in its range. A double, due to the way it is represented, has only 53 bits of precision, and therefore can be \"lossy\". This leads to a lot of confusion among programmers about floating point numbers. As a simple example, using a double, there exist doubles 'x' where x+1 == x. That's not true for longs. If you want to learn more, read \"What Every Computer Scientist Should Know About Floating Point\", it's a fantastic article."

What exactly makes seawater salty?
|
[
"There is salt naturally in the environment. Salt dissolves easily in water so any rain falling will wash it into the oceans via rivers. (Rivers are slightly salty.) The sun evaporates water from the ocean but salt does not evaporate and so it's left behind. In other words, the water cycle of evaporation and rain acts to concentrate salt in the oceans."

What would be the effects of consuming equal anoumts of caffeine and alcohol at the same time?
|
[
"Your senses would be deprived like you are drunk, but you would also have a lot of energy. Until you drink enough alcohol to pass out or both to vomit your guts out. They won't cancel each other out since it's depressing/upping different things. A chemical which counteracts alcohol/caffeine would cancel them. You would also urinate a huge amount."
] |
[
"You will get 5 hours of half strength. *Most of the time* (certain chemicals are the exception) including this case, dosage does not affect metabolic rate. In layman's terms; your body will \"burn\" different amounts of caffeine at the same rate. The only variable is how much is present at any given time. Caffeine has a half-life of 5 hours (on average; people can and do metabolize various chemicals at different rates), which means that every 5 hours, the level of caffeine circulating in your blood will be half of what it was before. So 50 mg of circulating caffeine becomes 25 mg of circulating caffeine in 5 hours. With another 5 hours it becomes 12.5 mg circulating, etc, etc."

How do animals hibernate for so long?
|
[
"I can answer the poop part of your question. Bears eat tons of grass prior to hibernation to form a butt plug. This keeps them from defecating. I'm sure other animals have a similar mechanism."
] |
[
"Because we don't need to. Hibernation is something that animals do to survive conditions that they couldn't survive normally. This largely only happens for mammals that live near the poles. In the winter, there isn't enough food to eat, so they hibernate to conserve energy until there is food. Humans evolved near to the equator. Where there isn't a harsh winter. We could find food all year round in that climate. So, humans had no need to, nor benefit from hibernating. So we never evolved to have that ability."

What is up with american TV shedules? Why is there huge mid season gaps and in some cases just random breaks of 1-4 weeks that can occur at any given point?
|
[
"The purpose of television is not to entertain...it is to sell ads. The TV schedule is a big chess game where you try to place the right show in the right time slot to make as much money as possible. You only have so many episodes, so you have to spend them wisely. Some weeks historically have fewer viewers than others. Sometimes non-regular events, like sports change the game. And sometimes they use an older, established show's time slot to try to break in a new show. And sometimes an actor is in rehab. It's a big chess game, and a lot of time why the players make the moves they do won't be readily apparent."
] |
[
"Our shows are more likely to go for 6 episodes per series really, especially on the BBC. It's sort of the standard length for anything that isn't a quiz show or reality TV show. The answer's pretty simple: We never started making \"seasonal\" TV like America did, hence why we use the word series instead of season, too. Your seasons are a set length at a set time of year, we just put shows on when they're ready and slot things into the schedule like a game of TV Tetris. The US and Canada are really the only nations that do that to any extent, with a \"fall season\" lineup and such. In other countries we pretty much just make it the length it needs to be (often between 5 and 10 episodes, though as said before, 6 tends to be the norm), instead of stretching it to the length of the season's schedule. On top of that, if it's a BBC series, no advertising means it'll be a full 30 minutes or 60 minutes, rather than 22 minutes or 44 minutes. That all adds up."

Why aren't countries referred to by the native word for them by the other countries?
|
[
"Many languages have sounds that other languages don't. It's why many people with the same first language have similar accents in a second language (ex: asians and 'L' sound). If the sound or technique used for pronunciation of a particular word is foreign, it'd be difficult for outsiders to say. On top of that, other languages can have different alphabets, or even different symbols altogether. Ex: 日本 is \"Japan\" in japanese, but do you, as a native english speaker, recognize that? How is it pronounced? (protip: Nihon) It's just easier to give everything a name in a way that is easy for you to say/write."

How do chess players guesses how many turns are left to a match ?
|
[
"Usually they aren't guessing -- they are actually playing out the best possible moves in their head, and seeing that in a certain number of moves someone will win."
] |
[
"There are several ways to draw in chess: * Threefold repetition. The same position, with the same side to move, appears three times. It doesn't have to be three times in a row. * 50 move rule. 50 moves are made without a pawn being moved or a capture being made. * Stalemate. The player to move has no legal moves. Their King is not in check but any possible move would put it in check. * Insufficient material. It's absolutely impossible for either player to checkmate the other. * Draw by agreement. The players may agree a draw. Now, if both players can see that the game is going to end up as a draw by one of the other reasons, if knowing the skill level of their opponent neither feels they will be able to win, then it's common to agree a draw. It saves the hassle. If draw by agreement was removed, players could simply deliberately repeat a position three times and claim the draw that way."

Why it's possible to stop breathing voluntary but not your heart beat?

how can movie trailers show clips of the movie, which I assume is finished, but not be shown for another year?

Someone steals one of these or uploads it themselves online. They try to combat this by making random parts of the movie black and white, so they know who it was that uploaded it/ who it was stolen from. for example, if the movie is black and white at 1hour 38min, that one went to Sam Smith.

Why are some house flies loud and some silent?
|
[
"This is a simple case of their genetics. Different sized flies, having different weights, require different amounts of lift to remain airborne. Depending on wingspan, and their strength, an insect will beat its wings at different rates. A butterfly, with large wings, will displace more air per beat, thus generating more lift. This demands more force, but must be done less often. Since the period of their wings' motion is below 20hz, and beyond the human hearing threshold, we cannot hear them fly. A housefly, on the other hand, displaces very little air per beat due to small wing surface areas. This, while not require a lot of force, must be done very often. Since they must beat their wings roughly 200 times a second, they produce an audible tone at a frequency of up to 1000hz. This changes depending on their flight, whether they are ascending, descending, or traveling laterally, as well as through the Doppler Effect, as they change position relative to the observer in significant time intervals."

How weather prediction works and why it requires massive computing power

Why are salt and pepper such ubiquitous ingredients in cooking?
|
[
"The human sense of taste has evolved to enjoy salt, because salt is important for your body to keep functioning. But that's not the only cool thing it does, it also seems to suppress our perception of bitter tastes, which lets other tastes like sweet or sour stand out more. Salt not only tastes pretty good on its own, it also makes other things taste better. Black pepper adds some flavor and a little bit of spiciness, but usually doesn't overpower dishes unless you add too much. Many other spices tend to be strong and distinct in flavor, and as such can \"take over\" a dish, instead of just enhancing it."

Why does 76 F/24 C with the heat running feel different from the same temperature with air conditioning?

"There are lots of things going on with how you think a temperature feels but the basic idea is that we don't really sense the absolute temperature. We sense differences in temperature. The simplest way to see that is being outside on a hot day vs. coming inside from a cold day. When you come in from a hot day you sense a large drop in temperature so it feels cold. If you come in from a hot day you sense a large increase in temperature so it feels hot. If that doesn't cover a case you are thinking of let me know and I can add more complications."

Why do some companies have different names for different countries? Like Lynx/Axe or Asda/Walmart

"In the case of Asda/Walmart, Asda was already an established chain of stores - Walmart buys it to a) gain presence in the UK where it has none... and quickly b) instantly gain Asda's customer loyalty and logistics (instead of establishing its own stores, its own infrastructure and THEN trying to win customers over. Once you've bought it, you don't want to immediately change the name, because that might confuse existing customers. Or indeed, if you're making money, why bother changing it? (in Europe, the Walmart brand might even have negative \"cheap American schlock\" connotations) In the case of Lynx/Axe, those are brand/tradmark issues. Essentially Unilever (the company) couldn't register Axe as a trademark in the UK so they had to call it something else. Brand trademarks are a regional thing.

How did we get from the "Golden Age" of Air Travel to the current state of air travel?
|
[
"The golden age of air travel was also the golden age of family road trip vacations. The services were caused by minimum price regulations that placed a very high minimum price for a flight (a low priced flight across the country cost the equivalent of about $1500 today). Because it costs far less than $1500 to fly across the country, airlines competed for travellers by offering services. When the regulations requiring very high minimum prices were removed, airlines began removing services and lowering prices to find that most people prefer lower prices to bundled services, so they deliver the services for which the most people will pay. Edit: Corporate greed means selling the most profitable services for the most money. It's foolish and not greedy to cut services people want at prices higher than the cost of providing them."

How does sleep debt/build up work?
|
[
"The first question to answer is, what is the point of sleep? Among some other functions, the primary purpose of sleep is for the brain to enter into a maintenance mode. Think of it as that 2am hard drive defragging that runs when you wouldn't otherwise be on your computer. Instead of space reallocation, however, the brain's process is biochemical and serves to \"wash and replenish\" the brain's cellular machinery, something that can't happen when the individual is in a waking state. This process is both reactive (meaning it doesn't do any good to do it before there's a mess to clean) and rate limited (which means that it takes X amount of time to achieve Y results). As such, the normal waking/sleeping cycle maintains an equilibrium of building up a mess and cleaning it up. You can't bank sleep. That would be similar to cleaning an already clean house for the sake of cleaning it and expecting any mess that you make in the future to come out of the extra work you did. It just doesn't work like that."

Why are states on the east coast so much smaller than the states on the west coast?
|
[
"The states on the east coast were populated first (European population that is...). State lines (colony lines initially) were devised in various ways, but all dependent on much of the east coast being populated very early. In other words, there were lots of people clumped up into various areas on the east coast and they divided themselves into colonies and then states. It took longer for Euro-Americans to go further west, and when they did the populations were very small at first. So the western territories were much larger areas, with very low populations, and many of those whole territories later became states. That's actually the way it remains to this day. If you rank the states by population density, California is the only western state in the top half, and it's only #11. Little Rhode Island has almost four times the population density as California."

How can gorillas and other herbavores get so big and muscular from a diet of essentially leaves and plants, while vegan humans tend to loose muscle mass on plant based diets?
|
[
"Nobody here has addressed the genetic basis and control of muscle mass and buildup in response to testosterone levels. One reason for example that a male gorilla simply builds muscle easily is because their muscles do not atrophy as easily and \"build\" with much less limitation for little exercise."
] |
[
"You don't need an extremely varied diet to become muscley. You need calories and protein. We don't synthesize all the proteins we need in our body from grass so we need to get them from different sources (animal meat, combinations of different vegetable sources, etc). Bison get the protein and calories they need from the grass they eat because their digestive system is equipped to get more of the calories locked into the cellulose of the plant matter and they synthesize the proteins that they need out of the grass they eat. The reason you need a varied diet is so you don't die from malnutrition because you lack B12 or vitamin K or something. Those things aren't necessarily required to become extremely muscular, but they are required to not die/suffer diseases from malnutrition. Edit: I also forgot the fairly obvious point the bison spend the majority of their waking time eating. Even with the better equipped digestive system you need to eat large volumes of grass to get substantial calories out of it."

How come when we look at something bright, we can see the image burned into our eyelids when we close our eyes?
|
[
"The way we see is that photons (light particles) from objects stimulate cells in the back of our eyes. This stimulation takes the form of light-sensitive molecules changing their shape as a photon hits them. When they are in this changed shape, they send a message to the brain saying \"I'm activated\", which the brain interprets as us seeing something. Now, the fact that something is really bright means that it gives off a lot of photons, and thus it activates a lot of your cells. Now, it takes some time for the light-receiving molecules to fold back to their deactivated state; so if you look at a bright object and close your eyes, there is a time period where the molecules are still activated and sending messages to your brain, so your brain thinks you're still seeing the thing until all of the molecules deactivate."

There is no scenario where guns will be banned, it's just not going to happen."

I suppose baby boomers look to him as a symbol of the future we were *supposed* to have and see his assassination as the moment when we went \"wrong\"."

how does drinking water coming into NYC not get dirty from the pipes?

"Licensed water operator here. No on in the US uses waste water for drinking water. Your shower uses drinking/potable water. The water goes down the drain to the waste water plant. They treat the water and send it to ponds, stream, rivers or to the ocean. Some drinking water sources could be a river. When I lived in VA the drinking water came from the new river. Its source was a bad design and was down stream of the next counties waste water plant. They usually try to keep drinking water sources up stream of waste water plants. They say it will be diluted or cleaned up by nature in 7 miles. Both drinking water and waste water plants spend a lot of money treating the water"

Why does my 21 inch LED monitor support 1080p but my 32 inch LED tv only does 720p?
|
[
"You are meant to sit closer to your monitor than you are to your TV, therefore resolution matters more on a monitor than it does on a TV. That being said, there are several models of 32\" TVs that support 1080p perfectly fine. One that only goes up to 720p is a cheaper model, or several years old."

[
"The laptop screen might be limited to 768P, but that doesn't mean that the video card on your laptop is limited to that. The video card probably supports a very wide variety of resolutions - its ability to drive a 1080p monitor will depend on the quality of the video card. e.g. some entry level graphics cards or the integrated Intel HD series cards can probably do 1080P graphics, just not that well. Technically you can have a video card with multiple outputs - eg. my GTX560 has an HDMI and two DVI outs - I could have that connected to a 1280 x 720 , a 1680 x 1050, and a 1920 x 1080 monitors for each output."

How does a woman's body know to sync menstrual cycles with other women that are frequently around?
|
[
"This doesn't actually happen, though it is a commonly cited myth. Multiples studies have shown that there isn't much truth to the \"menstrual sync\" hypothesis, though it can *seem* that way. In any group of adult women, chances are that 1/4 of them will be bleeding at any given time. If they're living in close proximity enough to notice each other's cycles, it's easy to notice overlap with each other and it can easily seem like you are moving in some sort of synchronized fashion. But you don't ever get a case where all the women have moved to be on the same cycle, like they're jumping rope together. That just doesn't happen."
] |
[
"Other mammals have a estrous cycle, meaning that they have a certain season in which they are most fertile during the year. Human women do not have a menstrual cycle, meaning they are most fertile at certain times of the (approximate) month each month. The evolutionary explanations for why this came to be are complex, so this could become a big question, but theorized reasons why we may have changed over the long-term course of history relate to the fact that we also evolved apart from other mammals in terms of the fact that we do not hibernate. For mammals that hibernate, it would be a waste of their body's energy for them to release eggs and then reabsorb them when they weren't fertilized while they were hibernating, as would happen if they had a menstrual cycle."

Why are knives and swords curved?
|
[
"There are a number of reasons. Take the Berber Arabs, they used curved swords because they often rode into battle on horseback and the curvature helped to stabilize attacks and balance weight so that they can be more easily used. In a more generic sense, curvature also assists in damage since it forces more of a point and the business end of the weapon, making attacks easier and more effective. Rather than having to run a straight knife along an object, swinging a curved sword will kill two birds with one stone, it will chop _and_ slice."

How do planes avoid collisions above the Atlantic where there is no radar?

[
"There are airplane “highways” usually separated by 10 000 ft. East you fly odd (ie 30 000ft) and west you fly even(ie 40 000ft)"
] |
[
"Air Traffic control maintains the flight corridors to ensure that airplanes are kept at a safe distance. ATC tries to keep aircraft flying in the same direction and speed at the same altitude. So the guy in front and behind you can't catch up. Aircraft flying in opposite directions are kept at different altitudes. That way if a plane is coming at you from the other direction it will pass **at least** 1000 ft above or below you. In the case of possible collisions aircraft are equipped with safety devices like TCAS (Traffic Collision and Avoidance System). TCAS units talk to each other and warn the respective pilots to pull up or down based on an algorithm to avoid a crash. > Too close for comfort at 30k+ ft and 600mph. From your perspective perhaps, but it's perfectly safe. You are 2000 times more likely to die in the cab on the way to the airport than in a plane crash."

"I have animals.. not cattle, but I have a donkey, llama, and sheep. Mostly what I see them do when flies start to annoy them is shake their heads, but I have seen them blink too. They stomp their feet or swish a tail when they are annoying them as well. Mostly though, livestock are not bothered by the flies until they start to get tickled by them, or are aware that it is a biting fly. Mind you I see some horses so irritated by flies that their owners have to keep fly masks on them or the horses are really annoyed. Livestock, and wild animals, eventually come to realize they waste a lot of energy dealing with flies so unless it is a biting fly, why bother? You will note that when you see pictures of people in poor areas of Africa they are sometimes seen with flies crawling on them and they don't seem to mind. I suppose it's because they don't care and have gotten use to the flies where as we get irritated easier."

Why does healthcare in the USA cost so much more than elsewhere, is it better than treatment elsewhere?
|
[
"In the UK everyone contributes to healthcare via taxes. More people contributing to a communal pool means lower overall costs for everyone. In the US everyone has to buy their own insurance and many people don't/can't. Smaller amount of people contributing to a communal pool means higher overall prices for everyone. Added to that people with insurance are technically covering those without because it's illegal for a hospital to turn down patients. If someone comes in with a broken leg or gunshot wound or whatever, the hospital is required to care for them. If they don't have insurance the hospital has to write it off as a loss and the prices for everyone else's care goes up as a result."
] |
[
"Without getting political, the strongest arguments against a single payer health insurance system in the US are: 1) The US is huge compared to other countries with universal healthcare -- 10x larger than Canada, 5x larger than the UK -- and the system might not be effective when it scales up like that. 2) Cost -- See #1 3) The US government is a bloated ineffective bureaucracy, which wastes money on inefficient programs and is slow to react to changes in the economic and social environment. If the lines at the DMV are 3 hours long, how will they do with hospitals? 4) Potential rationing of health services, leading to people who want or need care not receiving it because they're deemed \"less important to society\" either because of their age, health, or perceived utility to society."

Why do we feel sleepy in warm temperature rather than cold temperature ?
|
[
"I learned at least one of the reasons for this from a professor last semester. He's a kineticist (that's a field of chemistry) and very into endurance running -- and he told us just exactly why the perfect running temperature (high 60s to low 70s) is what it is: Pyruvate kinase Essentially, the heat outside actually interferes with the body's ability to make ATP, the energy molecule, out of the food we digest. This happens because pyruvate kinase, a crucial enzyme in ATP synthesis, is concerted mostly into a biologically inactive conformer at around 85 degrees F. This conformer is present in some portion at 70 degrees, but it's mostly the active form that dominates. After about 85 or so, you have a 60/40 ratio of the inactive to active forms. TL;DR heat slows down your metabolism and you run out of energy."

If the House always wins, how come most casinos go broke?
|
[
"Assuming that most casinos eventually go broke, lets look at a few things. First, its absolutely possible to be making money hand over fist and still go broke. The thing about having a lot of money coming in is that it makes you feel invincible. You can take stupid risks that get you sued or fined into the ground. You can neglect to fire staff that's losing you money day after day by half assing their jobs. You can agree to projects or plans that are too stupid to ever work. On the other hand, its not unusual for the owners of a business, like a casino, to decide its time to wrap things up. Maybe the design and theme of the casino is decades out of date, or the crowds just aren't coming in like they used to. When the time comes, its easy to stop reinvesting money in the casino, and to let it die of old age while the owners plan their next brand new casino. Maybe the new project will even buy the building from the old casino during bankruptcy."

They took power in Afghanistan back in the early 1990s, and were removed from power during the US war on Afghanistan. They're still around, and they're constantly trying to take back the power in Afghanistan. Al Qaeda is an international alliance of various groups that wish to impose similar conservative views all over the Islamic world. These days, their strongholds are Yemen (south of Saudi Arabia), parts of Pakistan (just east of Afghanistan), southern Algeria and, most recently, northern Mali (in West Africa). Back in the 1990s the Taliban helped Al Qaeda allowing them to live in Afghanistan and set up terrorist training camps. This is the reason why the USA attacked Afghanistan after 9/11. It doesn't seem like the Taliban today want much to do with Al Qaeda, however."

Why is a recent (less than a year) prescription required to order replacement contact lenses or glasses when it's OK to wear existing lenses or glasses for over a year?
|
[
"I get my eyes checked every year and because of my health insurance, I only pay a small copay for new glasses/contacts. You should be wearing the best corrective lenses for your eyes so if you have not gone to see your ophthalmologist in over a year, you should. Its not really OK to wear existing ones if your eyes have changed in that time as they can lead to headaches and damaging your eyesight even more. Which is why you should make it a point to get your eyes checked at least once a year."
] |
[
"If they give you the PD value, then you can go on-line and buy glasses for a tiny fraction of the price which they would like to sell them for. Without the PD value you may have the right prescription on the lens, but the lens will not be in their ideal position on your face which causes distortion. You might be able to get a close number by using a friend with steady hands and mm ruler. I saved about 90% on my second set of glasses by going on-line ($50 instead of $500)."

if a human embryo isn't viable, by what mechanism does the body decide to terminate? What is it that goes "this isn't working, scrap it"?
|
[
"A precise answer probably wouldn't be really eli5 but basically there will be some chemical signal if the embryo isn't viable on a cellular level. When cells die they release a lot of different chemicals that signal for other cells to recover and destroy the remnants. Also, when the embryo dies it stops secreting hormones that make the uterine wall grow into the placenta which will then start to die and detach like during a regular cycle. On the other hand, if there is some major genetic defect the blastocyst won't even implant into the uterine wall from the start and after a certain point if the fetus dies in utero the body won't necessarily terminate the pregnancy which can be very dangerous for the mother."

But at that stage several eggs are fertilized and most of these will spontaneously abort rather than go on to form a fetus. So is it the beginning of human life?

"Radio waves from phones could theoretically alter the readings of devices in the cockpit, causing the plane to go off course or interfere with the pilots' ability to communicate with air traffic control. There has never been a case of this actually causing a crash. Also, electronics can distract people during the safety presentations before takeoff, and become projectiles if the plane crashes, which is most likely during takeoff and landing."

Why do servers crash during a big launch? Wouldn't the company have countermeasures to prevent that before the launch?

"Imagine you are preparing for a party in which everyone is invited, but you don't know how popular you are. How do you prepare for it? Would it be better to have leftover food or to order more food when more people come? Would it piss off your friends if you don't have enough food? Answer these questions and you will have answers to your question."

"The maintenance window allows them to take servers completely offline for patches, reboots, hardware checks and any needed repairs/replacements. Some of the time is allotted for 'just in case' purposes, so that servers can be brought up a few at a time to make sure there are no catastrophic errors on startup. The reason they take servers completely offline for this is so that it can all be done in the fastest and most efficient manner without having to tiptoe around causing lag, disconnects, etc by doing it while players are still online. Today's particular maintenance, if I had to hazard a guess, has to do with the mass wave of bans of bots/cheaters that happened Wednesday - probably some server-side changes related to that, and to the authentication (login) servers being effectively DDOS'ed for a few hours by thousands of banned players repeatedly trying to log in at once."

Why don't American coins have numbers?
|
[
"So back in the day a dollar was a silver certificate that you could exchange for a dollar worth of silver. Coins used to be made mostly of silver, so a quarter had 25¢ worth of silver and a dime 10¢. There used to be a half dime, but it was deemed to impractical because of how small it was, so the nickel came out in a larger size made with cheaper metal."

Why does hot water feel significantly hotter on my face than on other parts of my body?
|
[
"A more sensitive and dense pattern of nerves and minute vascularisation in your face. Your back/thigh/arm doesn't have the same amount or type of nerves as your face. Your head is highly vascular as well, and is the warmest appendage from the core. You regulate your skull temperature quicker to keep your brain in its happy stasis. Feeling hotter heat on your face is a sensory warning to protect your noggin."

If illicit substances such as drugs were legalised, what would become of the black market? Would there be demand for something else?
|
[
"If there is way to make a profit the black market will find it. Take cigarettes, they are legal but because of the high taxes placed upon them it is possible to buy them in places that have low or no taxes and then sell them to retailers in areas with high taxes making profit for the black marketeer and a little more profit for the retailer. Legalized drugs would likely fall into a similar situation. If there is a way to make a profit there are always people willing to skirt the law or openly break it to take that profit."

"what would you consider success? The war on drugs is never going to lower the amount of drugs to 0. Unfortunately the war on drugs is fighting against itself so that the more that is taken off the streets, the more valuable the remaining drugs become. An increase in the value of drugs increases the incentive to sell them. There is a significantly more negative stigma on drugs compared to alcohol, and there was even back before prohibition. As for Tobacco, I assume it escaped the war because big Tobacco had/has a ton of influence politically, and the government makes a ton of money off of taxing it."

In theory, could an object with the mass of a grain of sand hitting the earth cause the same damage as a huge asteroid, if it were traveling at a fast enough velocity?
|
[
"First of all, > Energy = Mass times Acceleration This is wrong. Force=mass\\*acceleration. Energy = 1/2 mass\\*velocity^2 . To answer the question, if you were to ignore the atmosphere, *maybe*. In real life, earth is surrounded by an oxygen rich atmosphere. As soon as that grain of sand hits the atmosphere, it would compress the air a lot, immediately start burning, and then be gone. Super-high velocity very small meteoroids hit the atmosphere like this all the time. If they're bigger than a baseball, you see a neat little flash and call it a meteor. Smaller things just flash and gone. If the earth didn't have an atmosphere, then the answer is maybe, probably not. When the difference in size between two objects colliding gets to a certain point, you stop getting a collision and start getting a penetration. The result would be similar to shooting a bullet into the ground, there's no big \"smash\", it just drills a grain-of-sand-sized hole at the point of impact."

"Not moving relative to what? The Earth? The Sun? It's all relative. If you're not moving relative to the sun, the Earth will move by at about 30km/sec; fast enough for you to go from in space to on the ground in 4 seconds flat, but not really that fast in a astronomical sense, or if you were looking from far away (it takes the Earth 7 minutes to move one Earth diameter). You wouldn't hit the ground, of course; some of your constituent atoms might, after your body evaporates and unleashes about 7000 kg TNT equivalent; ~2.5 tons, or the energy of a small nuclear warhead. To go more in depth, as the planet smacks into you, you will vaporize very quickly upon entering the atmosphere, but your body's remains will not be slowed too much. It will impact the ground at probably a few km/sec under 30, and could possibly destroy a city sized chunk of Earth."

why can company's like U.S. Cellular claim to have 4G coverage everywhere but in reality, only have it in very few places?
|
[
"They absolutely never claimed that. That would be a complete lie. They always publish maps showing where they have 4G coverage."
] |
[
"As big as they seem they are not covering majority of the population. Their are entire states were they dont have service in. Like most cable companies they are one of 2 choices in most areas. Dont forget you can get satellite in 98% of places which is a choice.. not the best choice but a choice."

"Because believe it or not it affects what goes on around you. The amount of tax you pay, the amount of social assistance, whether or not wars both foreign and domestic occur. Look at what just happened with net neutrality. Had that not passed your Internet could be slowed down considerably while giving corporations the fast lanes of the Internet. So the better question is, why DON'T so many people care about politics."
