Why are cruise missiles used if ballistic missiles can reach targets faster? | Because nobody wants to anyone to think they're launching a nuclear first strike. There is no way to tell what sort of warhead a Ballistic missile carries. Launch one of these and you set off all kinds of armageddon. |
Phone speakers are so incredibly tiny, but have an incredibly loud sound, and is usually pretty clear too. How? | It doesn't? I often have to use headphones over my phone speaker to get any decent audio quality, and forget about showing friends songs my band recorded on my phone without headphones, my bass is almost left completely out of the speaker frequency. For the record, I have a Samsung Galaxy S5, but had the same problems ... |
Why does a new car lose so much of it's value as soon as it's driven once? | A dealer would have to explain to the next buyer why a car was returned so quickly after being purchased and driven away. I don't know about you, but I would be wary that such a car was a lemon or had hidden problems. Plus the dealer spent money selling the vehicle to you in the first place, completing paperwork, title... |
how do breeders ensure diversity among their animals' offspring? Wouldn't they have to constantly buy new breeding pairs? | To be blunt, they don't. Of course breeders take care to breed healthy offsprings, however on the small scale , inbreeding exists. Not between close relatives of course, but through many generations, which definitely can cause inbreeding-related-health issues. I doesn't get to bad obviously, because that would mean leg... |
Why do we have different battery sizes if they all do the same thing in the same way? | Many items have an optimal size and weight. You want a battery able to deliver the needed power and to stay charged for an appropriate amount of time and cost no more than a certain amount Your TV remote can't be the size of a brick or require an expensive new battery every day. |
Why do our brains have trouble visualizing more than 3 dimensions? | It does not. It's only if you try to imagine more than 3 spatial dimensions that you begin struggling, because the concept of space is a three-dimensional concept. Take an example graph like this: _URL_7_ What you see is: x-axis position, y-axis position, color, bubble size - so 4 dimensions. No trouble with that. |
Why do anti-depressants sometimes make teens and young adults suicidal? | This is interesting, I never knew that the increase in suicidal tendencies was more prominent in younger adults/teens. I was on SSRIs for about 6 months after a breakdown when I was 23-24 and I remember reading about the increase in depressive thoughts and actions as a side-effect. I found that where as previously I wa... |
What has Family Video done differently than Blockbuster that has kept them in business? | I asked this same question when i was interviewing for a job with the company. i was told the reasons are as follows: All new releases are one night only. Meaning they have a real high turnover and can make bank off of late fees.They also occasionally call customers who haven't rented anything in awhile, and offer them... |
How do you tell that a news source is credible? | There's really no objective answer to this. There isn't some kind of catch-all formula you can apply to ascertain the credibility of a source. The only solid tool you have at your disposal is cross-referencing coverage of the same issue between different sources and sieving out the commonalities.A Blog is not neccesari... |
Why did some cultures develop written language and others didn't? | Consider the metropolitan cultures vs hunter gatherer cultures why would a sub Saharan culture need to keep records? It's mighty hard to get there, and it's not en route for shipping or trading.Also probably other reasons |
What started the hatred of Homosexuality? | The core of that question does go back to homosexuality being a sin in the eyes of religion. In the west that religion is predominantly christianity and so it follows that the hatred of homosexuality can be traced back to it being against God's teachings.What advantage was to be gained by encouraging it? There is no ev... |
- Monsanto. Please. Thanks. | Assuming you mean about the whole terminator seed thing here goes: Imagine that everyone is trying to grow strawberries but despite all their efforts the strawberries will only grow so fast and they die whenever it gets cold. You spend ages working on a super-strawberry and eventually you make one, it grows really fast... |
why haven't the large and heavy lead batteries in cars been replaced with newer lithium or nickel battery technology? | CURRENT, not voltage. And since the cold cranking load can hit 800 amps this is pretty important for starting internal combustion engines. That aside they're very old and mature technology that's unlikely to cause any unexpected problems . |
When an animal looks into a mirror, does it actually know it's looking at itself? | Some do, some don't. Dolphins, whales, elephants are arguably self aware. Some animals can learn that it's themselves. A couple of the kittens I've had would attach the mirror like it's a strange cat, but after a while they would realize it's not another cat. |
What exactly is MS. | > he described it was basically he could no longer function in society or have a job and the rest of his life would basically just be him collecting a disability check People have described the process of MS pretty, so I'll just touch on this part. MS is a highly variable disease, with highly variable progressions. Som... |
Why is rail travel in the U.S. so terrible? Amtrak costs more, takes longer, and is less safe than air travel. Why? | In 1950, in anticipation of a crippling strike by railroad workers, President Harry S. Truman issues an executive order putting America’s railroads under the control of the U.S. Army, as of August 27, at 4:00 pm He had just ordered American troops into a war against North Korean communist forces in June.

My skin is dry. Why dosn't putting my hand in water simply re-hydrate my skin? | Water strip's the natural oils of the skin away just like it strips dirt and germs away. Lotions are synthetic oils that do the same thing as our natural oils. |
Why do old ladies cut their hair short? | Hair tends to get thinner with age, so long hair often doesn't look as good on older people. Also long hair is a serious pain to take care of, and if they aren't trying to attract a man, they'd rather be comfortable. |
Why is Western Europe so socially liberal? | It isn't *that* left wing it just seems it compared to the prevailing self centred right wing culture in America. We look on and wonder why such a heavily self certified Christian country can be so far from anything Jesus ever stood for. |
Why do jet cars blast fire out their asses, Where-as a plane will "wind up" and shoot down the runway and take off | As others have already noted, what you're seeing is most likely afterburners. Passenger jets and their engines are designed for fuel efficiency. Afterburners can burn hundreds of pounds of fuel in a short time. Military fighter jets use afterburners in certain situations, as seen in this training video _URL_0_ |
If we aimed a mirror at the night sky, would the light from the stars bounce back and travel for another trillion or so miles? | Just for fun. If you could use a large enough prism to capture and concentrate enough light maybe. But, like, it'd have to be a big Goddamn prism though. Otherwise you won't be reflecting enough light to travel trillions of miles; the photons will have dispersed too much after a short distance to even be visible to som... |
Why do people hate Jar Jar Binks? | Personally, I see 'ol JarJar as a collection of the most annoying behaviours of several poor and/or immigrant subcultures. That makes him both politically incorrect and annoying. I think annoying wins. On top of that, JarJar is a subtle chastisement that we should leave politics to the professionals, you know, cause *t... |
Why do some neighborhoods/housing communities have odd speed limits ex. 13 mph | Like everyone said, it's to gain the driver's attention. Drivers typically see a speed limit of 5 and push 10. They see 30 and push 35. An awkward, less common speed limit tends to eliminate this problem. In Disneyland the parking lot speed limit is 14 mph. Having kids running around, Disney feels this can help prevent... |
why does reddit work perfectly when I'm using mobile data but not when I'm using WiFi? | It sounds like the WiFi you're using isn't working great. But as mentioned before, more information is needed. Do you experience the same issues on all WiFis you're using or just a few? Do other sites have the same issue. Are you using a reddit app or a browser?", 'I have had the same issue with whatsapp In mycase, wif... |
Why are there so few execution drugs? | There are very good drugs for painless euthanasia. The developers of those drugs will not sell them to US prisons. Compounding pharmacies are not as tightly regulated by the FDA and for some reason are able to source certain drugs that wouldn't otherwise be used for euthanasia to prisons. Most prescription drugs in the... |
Sleep talk. How and why does it happen? | As a sleep talker, I'd like to know this too, and how to control it. It drives my girlfriend bonkers |
How do dying people "wait to go" so they can see their loved ones one last time? | As /u/rrssh already mentioned: Your state of mind partly controls your body functions, like adrenaline level. To add to this: Many terminal diseases are painful. You can stop or at least lower the pain with drugs, but they have side effects: It's harder if not impossible to keep a clear mind - and they may accelerate t... |
Why is cocaine ingested through the nose? Like, isn't there a better way to get it into the body? | There are 3 common ways of doing drugs.. Injection, Inhalation, Ingestion. Injection gives an immediate high that lasts a short time Inhalation gives an almost immediate high that lasts a bit longer than Injection Ingestion is the slowest, and is when you eat something and it travels through the digestive tract. The dr... |
Do fish in schools communicate to stay together or is it pure instinct? Do fish communicate at all? | We don't know much yet, but some fish use farting : _URL_2_ Alternatively, many fish have what is known as a lateral line, a series of nerve channels on their body that is very sensitive to pressure changes nearby. This allows them to sense what's happening around them without visuals and change course as needed. I'm o... |
What exactly prevents an American from establishing an all-volunteer army to fight ISIS in a manner similar to the situation in the Spanish Civil War? | I'm actually rather surprised that Erik Prince and his merry band of mercs haven't been contracted by one or multiple foreign nations to engage ISIS. He already has a large core of well-trained and highly motivated operators who could take the fight directly to the enemy . Too bad its a regional cultural problem that w... |
Why does it feel like we only sleep for like 5 minutes when in reality it's more like 8 hours? | I think the main factor in this is that you don't remember sleeping. Your brain doesn't regard experiences while asleep as useful memories, so it doesn't record them. That would be why you have difficulty recalling dreams unless you woke up during/right after having the dream, and even then it will fade quickly unless ... |
Why do governments have secrets? | You don't want enemy countries to use your own technology/tactics/strategies/whatever against you, so you take steps to hide that information from them.For military and police: + do you agree that identities of undercover agents must be secret? + their meeting locations and passwords? + other ways of communications? + ... |
Why do hotels use two flat sheets instead of a flat and a fitted sheet when making the beds? | Partly what not_falling_down said, partly because flats are much more convenient to store because they're easier to fold. I've known housekeepers who can fold a fitted like nobody's business, but it's still much more difficult than folding a flat. When you're storing a couple thousand sheets, this makes a big differenc... |
Tumblr. I've only seen it through Reddit's eyes. Is it really a place for pansexual, wizard, reverse-rape feminist, eagle gendered, proudsexuals? | I use Tumblr exclusively to look at porn myself. Because I really don't care what anyone thinks about anything. So I haven't seen a single thing about Social Justice or made up genders or anything like that. I like it because I don't really have to look up porn, it's just beamed directly directly into my eyeballs with ... |
Why is it that the deeper you go down in an ocean, the colder it gets, yet the deeper down you go underground the hotter it gets? | The ocean is liquid. Liquids undergo convection, meaning the liquid at a denser temperature settles to the bottom. Water is at its densest just above it freezing point . So the surface waters of the Arctic Ocean and around Antarctica cool off until they are right temperature so sink down to the lower layers, and then t... |
Other than efficiency, what does pumping premium gas instead of regular do? | Depends on a few things, if you have a very high end engine, its made to run higher octane fuel. If you have an older car, and the premium gasoline is ethanol free, that could explain it. For smaller engines and car engines not designed for it ethanol runs poorly compared to gasoline. Whether your premium has any ethan... |
how do apps such as snapchat make money, even though they have no cost and are ad free? | Another way to monetize a free app is to sell user data. Most of us blindly click on accept without actually reading what we're agreeing to when we install the app", 'Snapchat is not the product they are selling. You are. The user is. Data is a commodity, and snapchat is merely the interface that the company uses to co... |
Before feminism, how did women being the lesser sex become status quo? | One reason might be because of child rearing. Before modern medicine people lived far shorter lives and, more importantly, far less children survived to become adults. Because of this, women would be expected to effectively spend most of their adult lives being pregnant. This being a time before formula milk also means... |
Why does the Westboro Baptist Church pickets funerals? | The short awnser, because they're assholes. The longer awnser they think that a lot of bad stuff that's been happening. are punishment from God because the world isn't following the shitty worldview that they believe in. And they're protesting to carry out this message. |
Why don't job listings show hourly wages or salary? | Because if they're willing to pay $12 / hour and mention it, then they will have a 100% chance that the successful applicant will be hired at $12 / hour. OTOH if they're willing to pay $12 / hour and don't mention it, they may have a 75% chance that the successful applicant will turn down the job if they can't negotiat... |
How is it that we have an installation at Guantanamo Bay, Cuba when we have poor relations with that country? | We've had it since before Castro took power. We actually keep sending them rent but they don't cash the checks.bigger gun diplomacy. by some clearly BS loophole it's been begrudgingly agreed it can still exist. in reality, the US wants a base there and there's F*** all cuba can do to "convince" it to leave. |
The story of the Kingdom Hearts series | If you want a rapid summary of the entire series using only pictures and no names that may bog it all down I highly recommend this google doc. It's basically one guy who arranged the story like a picture book. _URL_4_", 'I only played KH1. Do future games include Disney characters, or is it mainly stories about the Org... |
Why do most professional sports(US) require 4-7 games to determine the winner in the Finals(or equivalent), but football needs only one? | All games, sports or otherwise, started as competitions of skill and chance. To eliminate chance they made the games a series of events - best of 5 for example. First one to win 3 games is declared the winner and chance takes a back seat. The World Series was best of 7 and best of 9 a few times for increased sales , bu... |
How does starting a sentence with a short filler phrase like "yeah, so" give you time to think of an answer as opposed to just being silent for that second? | It depends on the situation. Use of filler words can come across as more friendly and informal they are often used in both social and less formal work situations. Eliminating these words comes across as more confident but also more aloof. It's ideal for both public speaking and the majority of business presentations. I... |
Why does the electricity in some cars get cut off when starting the engine? | The battery is being used to forcibly crank the engine over. This isn't a trivial thing to do, as the air in the cylinders is resisting the starting motor, so it takes more than a little electrical oomph to do it. More going towards turning the engine over means less available for other electronics in the engine. |
What would happen to a deep sea fish that is used to thousands of pounds of pressure that was brought to the surface. | Here's a picture of an angler fish that was brought to the surface: [here] if you notice its brain can be seen in its mouth. If I remember correctly, the internal pressure of the fish is greater to stand the external pressure at depth. **tl;dr** look at this crazy fish with its brains in its mouth", 'Not 100% sure but ... |
Why is Greek life such a big deal in America compared to Canada, and what exactly is so special about it/what does it entail? | Going Greek allows you to be part of an exclusive group of people. Some people do it to party, some do it for friendship, while others do it for the networking opportunities after college. For some it's just 4 years of their life and that's it. For others, it's part of them for their lives and they continue to give bac... |
Why do late night shows use hand-written cue cards when they could easily afford a teleprompter? | They're more often used as talking points. They try to make the conversations/ jokes as natural as possible. They just use the cards to hit some points |
Why do the people of Detroit don't want Nickleback to play at the lion's thanksgivings game? | One person's trash is another person's music. Some people like Nickelback, but the majority view them as talentless and awful. A LOT of people just straight up don't like Nickelback .Questions like this should not be in ELI5I thought it was kinda obvious. No one wants them there. |
The sensation of "too quiet" | Seen this on vsauce's youtube red series mindfield there was some experiment, that they replicate here _URL_0_ that shows people basically crave stimulation. Left alone to themselves in a quiet room people prefer to zap themselves with electricity, causing pain, rather than sitting in silence. Lack of stimulation, as e... |
Why is the UAE so amazing and secular when it comes to technology and engineering but poor when it comes to social justice? | They throw money at european/North American companies to build expensive shit They're xenophobic against people of a lower class than them . |

It seems like you enjoy it. You have a real talent. I liked reading these a lotWow, flabbergasted1 FTW. . . that was awesome. You should to... |
Why is Gender identity disorder regarded with validation and respect but Body integrity identity disorder is not? | But they're not really the same, that's the thing. The ways we identify them, the ways they present themselves, the effects on the person they're all very different. Just because they're both considered identity disorders doesn't automatically mean they've got a lot in common. Also, GID is no longer a valid diagnosis i... |
What makes your stomach hurt when you are hungry and what causes your stomach to growl? | I was just wondering this yesterday. I always have immense pain and nausea when I'm hungry in the morning and I was wondering too. |
How detailed are reflections in mirrors? | Green light is 550 nanometers, or about 20 millionths of an inch: so you couldn't see much finer detail than that. But that would be true for looking at the real object as well: so if you could make your mirror perfect enough, the visible reflection wouldn't necessarily be any worse than the real thing. If you want to ... |
How are tablets so much cheaper than smartphones? I get that it's harder to fit all of the technology into a smaller device, but once they figure that out it's less materials overall | It's because they can charge more for a cell phone. With carrier subsidization and now installment plans, it is much easier to sell a $650 phone behind a $200 contract or $25 a month than sell a tablet with the same or better specifications for $650. For example, the iPhone 6 costs [$247] in parts and labor, while the ... |
Why do you puke when you work out too hard? | No idea why it happens but I joined a gym for the first time in my life last month. Am underweight and weak, had a PT give me a full-body sessions.

Why is the US so slow to implement credit card chip technology? | Australian here - are tap payments very common in America? I mean the method where you just tap your card against a reader and the payment comes out. It's called PayPass here but I imagine that's just a brand name: _URL_0_ It seemed silly to me at first, but now I couldn't live without it.Has there been any evidence th... |
How is it legal for the Homeowner's Association to dictate what I can/cannot do on property I've purchased? | The property owner signed a contract that they would abide by the HOA's rules when they bought the place. And there's a binding clause in there that say you can't sell it to someone who doesn't also agree to the rules. |
why does the inside of the ship, tank and train have so many knobs a and analogue equipment where as the u/traviss22 tractor is the "most up to date". | Not just fail safes, tanks/ships run on older technology and it would cost too much too update. Even newer tanks being built are under old contracts so the manufacture doesn't have to update and won't because it is cheaper. New aircraft like the F35 and F22 so have a lot more digital controls, but flight critical contr... |
What truth is there behind the stereotype that southerners are dumb, and how did it happen? | I mean just looking at statistics the South isn't always looking too good. With the exception of cities and occasional wealthy areas the rural South is pretty destitute and rife in poverty, obesity, and drug use. Also city livers have often had a distance for people living out in the middle of no where for as long as p... |
How does the blue Stick at the dentist work, so that the material gets hard. What's happening there? | It's called a dental curing light. The filling material contains molecules that are sort of on their own, but when exposed to a certain type of light they will absorb the energy from that light and it causes a chemical reaction where the molecules all join together very strongly. This is what hardens up the filling. |
Reddit, how the fuck does a mortgage work? | 1) find a house for $100K 2) save up $20K for a down payment 3) borrow $80K from bank, put house up for collateral on that loan 4a) make monthly payments for 30 years, and pay off loan 4b) don't make monthly payments, bank takes your house, sells it for $80K to cover what you owe on it |
Why does the American presidential race cost millions of dollars? | Ads cost [a lot] of money if you want to reach millions of people And having offices and staff all across the country isn't cheap either.It is a very large country with a large population, making it expensive to run a nation-wide campaign. Compare the size of the US to the UK, for example. Of course, Citizens United ru... |
Why is gas under $2.00? | Crude oil is refined to create gasoline and other petroleum products. 1 barrel of crude creates about half gasoline, quarter diesel, quarter other products.

When a TV remote is running low on batteries, why does pressing the buttons harder make it more responsive? | Here's another tip for when your remote batteries are getting low. Open the battery cover and spin the batteries around, or just take them out and put them back in again. |
We know the body “burns” fat when losing weight, but how does it get rid of all the extra nerves, blood vessels, and skin cells it creates when gaining weight? | Everybody's talking about fat cells and not really answering your question. Short answer: it doesn't. As a plastic surgeon, we work with massive weight loss patients a lot especially when removing excess skin. Skin has a certain elasticity and ability to contact back to a certain point, but above that you get stretch m... |
How do those 99c-and-free-shipping items make any profit for the seller? | My immediate thought is an economy of scale. You increase production to reduce the price per unit produced. Now, it's likely that many of these sellers are separate from the production process, so they can buy in bulk to cheapen the price. It's like those deals in stores where if you buy a 6 pack of beer, it's cheaper ... |
The so called United States fiscal cliff in 2013, from a neutral point of view. | Imagine a couple having their house painted, but they can't agree what color to do the bedroom in. They tell the painter to do the bedroom last, and pick a color they both hate, in the hopes it will motivate them to come to a compromise of some sort. Well, the painter is just finishing up the living room, and they stil... |
Why is a tunnel ever preferable to a bridge when crossing water? | In addition to the answers given, another reason is that a bridge might interfere with a significant natural, cultural or tourist site. e.g. when Sydney wanted to build a second major harbour crossing, they didn't build a second bridge, they built a tunnel. Why? Because a second above-ground crossing would have cut a s... |
Why do they have pills for animals that prevent insect bites (frontline, comfortis) safely, but humans do not? | It is my understanding the drops for cats and dogs are neurotoxins and some also have insect growth regulators. They don't stop the insect from biting they just kill them if they do. If the insect doesn't die it generally can't reproduce anymore. I know of a case where a lady could not find drops for her daughters cats... |
Why do we die/age? | Some parts of aging proved more useful for survival, ironically enough. Aging specifically helps keep a shorter-term reproductive cycle, which when the main improvements in a species come from reproduction, you want to reproduce as fast as reasonable to improve as quickly as possible. Death also generally happened much... |
why do colleges and even high schools emphasize plagiarism so much | First, whenever you write, you should write as if it were being published. Even if you are only giving it to your instructor, you never know if he/she will ask you to submit it to a student review or a conference. Second, your instructor knows that you did research. They know that a lot of the ideas are not your own. T... |
What was the purpose of the Death Star? | It's the ultimate deterrent, the nuclear option a millionfold. A planet's government might be willing to risk invasion or blockade, but not utter annihilation. The thinking was that you'd only need to actually fire the death star once or twice to terrify anyone on the fence into joining your side. The station itself wa... |
what are the palace guards in England trained to do? | They're like any other military or law enforcement professional. They're trained to protect whatever it is they're guarding. Edit: Grammar |
Why are you so horny when you have a hangover? | Being that I'm horny most mornings anyway, and drink most evenings to excess, I always thought it was just coincidence. |
why is travel, or being "well-travelled" so admired? | Because you need a lot of cash to do it. Poor people can't travel. Nobody wants to be poor. That's why in nearly every female's personal ad, they mention love of travel. HOWEVER, if you are able to travel on the cheap, you can get exposed to other cultures and get to see firsthand how big this world is. So there's that... |
Why does a the most well-funded and powerful military on earth outsource to companies like Blackwater? Why don't they just...do it themselves? | It's because it's more efficient for jobs the military isn't as good at or doesn't have the flexibility to do so. Contractors like Blackwater aren't there to do the fighting a company of Marines might do, but they might be doing jobs from driving supply trucks to setting up kitchens on base to even providing janitorial... |
Why does eating simple carbs (such as sugar or white bread) make people fat? | You are asking two different questions: 1) how does the body turn sugar molecules into fat cells? This is very tricky. Except in very rare conditions, you body just stores the fat that you eat. It doesn't matter though. If you body saves the fat that you eat or converts carbs to fat and then stores it, the only thing t... |
Why are so many Americans hooked on opiate pain pills? | We are a pharma loving people. There is a newer prescription pill epidemic and I think it partially reflects that. People tend to think that because someone gets a prescription for these pills that they are safe and sanctioned. And in ways it is better than heroin in that it is regulated. However, many people are going... |
How do insurance companies afford to pay out such large sums of money when individuals buyers of plans do not pay as much as they receive? Where does this money all come from? | I'm not sure if anyone has mentioned it, but when an insurer takes a premium from you, they only have to keep a certain amount in reserve to pay out claims. The rest they can invest, this leads to a larger pool to pay out to shareholders etc. In lloyds of london, before solvency laws were tightened up, some underwriter... |
Why do people donate hundreds to thousands of dollars to streamers on twitch? | As someone who has some experience in this kind of twitch communities / organizing events, let me tell you a few things. - You don't know the financial situation of the people who donate money. To many $500 on a stream they enjoy is not a big deal. Just like you would pay $10 to go see a movie. - There is not that many... |
If trees need carbon dioxide to survive, how did they exist before land animals spawned | Carbon dioxide exists and occurs naturally in the environment. Animals aren't the only source of it by far.For a very long time, all life on Earth was microbes. Microbes developed photosynthesis to convert CO2 into O2. This carried on for a long time until rocks and such because saturated with O2 and it began accumulat... |
If Antarctica still has an average temperature that is below freezing, how does a couple decimal point change in temperature cause such severe melting? | It not that a few tenths of degree will cause melting, they won't, it's that the temperature has changed so much that the mathematical average has actually risen a few tenths of a degree. Changing the long term average takes a lot of periods of time with warmer temperatures. It is now significantly warmer significantly... |
The north Carolina gay rights laws. | The state passed a law that invalidated all of the city/county protections for LGBT people , so they effectively don't have any . |
Why do people have trouble comprehending large numbers? | Because humans don't deal with scales that big it's easiest to describe it with time. It's easy to think back a year or a decade because we experience that length of time we can understand it. But tell someone to think about 10 billion years ago. It's hard we have nothing to base that on making it hard to grasp. |
Why can't my computer just sacrifice and transfer a part of it's own battery to my phone to charge it in seconds? | For the same reason you can't plug your phone in and have it charge in seconds. Your battery just can't charge that fast. You can definitely plug your phone into your computer to charge it. But charging really fast is a completely different issue. The faster you charge, the hotter the battery gets. And getting when tho... |
How bad for you is it to have one or two beers a night? What does it actually do to your brain/body? | One to two isn't bad, actually some benefits to beer if you keep it at no more than 2. One thing I learned in a class is that it's better to drink 2 beers a day every day of the week compared to drinking all of them in one sitting. Only thing I would worry about is if you turn in to someone like me and start drinking 6... |
What is that horrible feeling you get on your fingers when you feel a microfiber blanket/cloth? Feels like its going to rip your skin off or something... | Maybe I don't know what microfiber you are talking about. I'm thinking of those super soft ones that are irresistable to me when I see them in the store. I can't imagine being horrified by them.

Why are pain management doctors required to obtain periodic drug screens but medical insurance companies not required to pay for those drug screens? | Pain management clinics order as many drug screens as possible because they get to charge for them. Insurance companies won't pay because they aren't necessary. Patients still pay it because they are often dependent on the pain medicine, and have no other choice. Source: I am a doctor, with colleagues in pain medicine ... |
Why can't you go as fast on land as in the air? | Air resistance is a major issue in how fast you can go. The higher up you go, the thinner the air, and the less resistance there is. The less resistance, the faster you can go. That's why planes fly at about 35,000 feet. |
What would happen if millions of people took to the streets and tried to overthrow the government? | well it sort of depends. In the US? They might gain some amount of success, but you'd have to have a pretty extensive number of people across a very wide amount of area. The US is too big for the entire population of one state to really influence anything. On the other hand, if you pick a smaller country perhaps one w... |
How did a fly survive being microwaved? | Short answer: the distribution of microwave energy in your microwave is very much uneven.

why do so many numbers involve repeating decimals | Not entirely sure what exactly you're asking, but I'll do my best. Our number system is in base 10, and 10's prime factors are 2 and 5. Because of this, dividing by any number that can't be factored into some number of 2s and 5s will give repeating decimals. If we look at dividing by the numbers 2-20, we see that we ha... |

Why are most of the herbivores mammals like elephants, rhinos, hippos, giraffe, etc. so big in size? Even in the jurassic era the largest dinosaur was a herbivore. | Plant leaves, not counting the ones we've altered via selective breeding are generally poor quality food. Plants have cell walls that make it difficult to extract the nutrients from it. Unlike animal cells which are surrounded by a membrane. So to compensate, herbivores have to either eat a lot and race it through the ... |

Intelligence Quotient / IQ, what exactly is it and what are its criticisms? Why is it potentially wrong? | I can't tell you why it's considered inaccurate, but I can give you a few famous cases of incredibly smart individuals with a comparatively low IQ. [Dr. Richard Feynman], Nobel Prize winner in physics, had a reported IQ of 125, yet he is widely regarded as one of the smartest minds of his generation, and is known as th... |
