How do people and animals not impale themselves on tranquilizer darts when they fall?	[ "Nobody uses tranquilizer darts on people. Unlike in movies, in real life a darted animal doesn't just fall over. It slowly gets sleepier and more lethargic, and usually lays down." ]	[ "I read a great article on that a while back. I'm trying to find it again... Basically, during the night you wake up (or semi conscious) for seconds - minutes between cycles, but you have no memory of it in the morning. As the night passes, those moments come more often. So in the morning, say you start one of thos...
Why is a flight to London more expensive than a flight to Edinburgh, Scotland when I have to connect in London?	[ "Never confuse the price of something with the cost of something. The price of something is a reflection of how much people are willing to pay. The airline made a profit flying the two of you to Edinburgh via London. They're making $800 more profit from the ones getting off at London." ]	[ "It's all about relativity. If the Hulk ran for a quarter mile, he'd only appear to be moving a few dozen widths of his body size. If a dragonfly then traveled the same distance and speed, it'd appear to be moving thousands of widths of its body size. So they cover the same distance but relative to their body size ...
Why are uranium and thorium so (relatively) stable despite all of their neighboring elements decaying hundreds of times faster?	[ "I would look at the nuclear shell model on page 5 _URL_0_ It has there the number of nucleons a nucleus needs to fill a shell (analogous to the noble gases in chemistry). The last magic number before uranium is 82 which is lead. But if you look above there, the next filled level would be 10 higher which is 92 for ...	[ "It depends on how close the explosion was to ground level, and how big it was, how much protective gear you are wearing, and how long you would be staying (are you coming out of hiding just to leave the area, or are you planning to live there?) TLDR: Bigger warheads, and detonations that are closer to the ground ...
Why do some places have power lines underground and others above them above ground?	[ "In addition to cost vs safety, some times in the country you'll see an aerial line come down a pole and go buried for a short period of time and go back up the pole, this is usually because some farm equipment is too high to make it under the lines without damage so they bury them in this area. Other times you'll ...	[ "Usually it's from old season or when they have a surplus of a product that they thought was going to be a big hit but didn't sell.

What's so special about pickled cucumbers that they beat out all other pickled foods for the name "pickle"?	[ "Well, at first I said \"they were the first\" but obviously the automatic moderator doesn't like that so please enjoy my long comment explaining why i cannot simply post the answer, they were the first ones" ]	[ "The biggest difference is that your 401(k) is what's referred to as a tax deferred account. The money you deposit is not taxed until it is withdrawn. This may seem like a trivial distinction since you're taxed on the money either way but the reasoning is based on the assumption that the 401(k) is a retirement acco...
If you made a sheet of material that was only 1 atom thick would you be able to see it?	[ "Yep, you'd just about be able to make it out. For example, a graphene monolayer absorbs about 2.3% of light incident on it, so you'd be able to see that it'd be very slightly darker than the surrounding air (if freestanding.)" ]	[ "This has actually already been done, [here is a video](_URL_0_). The problem is that the image coming from the eye is full of gaps and errors which our brain has evolved to cover up. We think we see a perfectly clear image but in reality it's distorted and constantly waving back and forth." ]
Does the Time Warner Cable/Charter merger violate anti-trust laws?	[ "Anti-trust laws give the Department of Justice the authority to make that call. It is decided case-by-case by the courts. The Antitrust Division of the Department of Justice did indeed file a lawsuit arguing against the merger. In court, \"New Charter\" agreed to a list of concessions and regulations in order to c...

How is it that copying a 1Gb file takes less than a minute, but copying 22,000 lines and 20 columns in MS Excel takes forever and potentially crashes the software?	[ "You can compare it to trying to move a 10 kg box filled with marbles, and 5 kg of marbles without a box. For some reason moving the marbles are easier when they are in a box, even though you are moving more." ]	[ "Simple analogy: think of a core like a lane on a highway, and think of the clock speed as the speed limit. Two cores would mean there are two lanes on the highway. Now, let's define a couple of systems. * System A: single core, 1 GHz (30mph, one lane) * System B: dual core, 1 GHz (30 mph, two lanes) * System C: s...
Could Quantum Entanglement be used to create 'perfect' encryption?	[ "Yes, you could use quantum entanglement to create a one-time pad. This is a form of encryption where the key is as long as the plaintext, and the encrypted message is therefore completely useless to anyone without the key, since there are just as many keys as possible messages. ...but you're going to have to meet ...	[ "You should read [this](_URL_0_) from PBS/Nova. One of the interesting scenarios is the Hagedorn temperature that appears in string theory.

To what extent did the Byzantines (Eastern Roman Empire) attempt to save the Western Roman Empire from barbarians?	[ "In the early 6th century Emperor Justinian and his chief general Belisarius managed to reconquer the entire Italian peninsula as well as parts of Spain and North Africa. Unfortunately the constant campaigns against the various barbarian tribes strained the Empire's resources and as a result were unable to hold on ...

Is it true that organisms with exoskeletons can only grow to a certain size because of gravity?	[ "Physics of volume. Strength is proportional to length squared whereas mass is proportional to length cubed. At a certain point the thickness of the exoskeleton would cause the legs of the insect in question to collapse under the strain of holding up its own body weight. Combine this with the notion that every time...	[ "This won't be the most in-depth answer but it's kinda like this Plants and tree love sunlight.

I'm fascinated by ancient and "lost" civilizations/cities. Can you tell me about some I haven't heard of?	[ "At a guess you might not have heard of Ai Khanoum. The name is Uzbek and means 'Lady Moon' but the city was founded by Greeks sometime around the end of the 4th century BC. It was one of many founded by either Alexander the Great or Seleucus (we aren't sure which). Its ancient name may have been Alexandria Oxiana,...

Rock climbers, how do camming devices work?	[ "they redirect force to increase friction due to their shape. you compress one and shove it in a crack - when you try to pull it out, the pulling force cause the cams to press outward against the sides of the crack. The more weight you put on it, the harder it tries to stay put." ]	[ "In addition to /u/CoderInPhoenix's explanation another big factor is weight. Although I'm pretty sure taking only the camera portions of an iphone would be significantly lighter, ounces count. So that coupled with making it durable enough to withstand tons of sandblasting and using old technology makes it actuall...
Why do humans not grow facial hair until puberty?	[ "Thickness of body and facial hair in humans depends on levels of androgens like testosterone in the blood system. Humans experience an increase in androgen levels as part of the general change in hormone levels during puberty. As a result, those hairs grow in thicker." ]	[ "We don't NEED those things just as other animals don't as well. It is just a luxury we enjoy." ]
Why did American culture change around 1964?	[ "Not trying to be a hater but this sounds awfully like a highschool/college essay question which aren't really allowed in this subreddit.

Why do some ants smell like bananas when you smush them?	[ "Counter question: why are you going around smushing and sniffing ants? Like, different types of ants on different occasions." ]	[ "I took a primatology class in college and was told that there are two types of male orangs. The flanged males are big dominate guys and they will fight over females with other males to gain dominance and the right to mate. The unflanged males are sneaky bastards. They chose not to waste energy fighting other males...
At what point in evolution did animals start using blood?	[ "Blood evolved with circulatory systems in invertebrates originally. It was one of the earliest adaptations of multicellular organisms and probably started in the Cambrian.

why is there a visible stream of air coming from either a jet engine or airplane wing tip when flying? also what do the wings and tip on the back of a plane actually do?	[ "Jet engines produce water vapor as one of their byproducts, so that's why you sometimes see it coming from the engine. As for the wingtips, depending on the aerodynamics of the wingtip, as it travels through the air it can leave vortexes of swirling air behind it. One of the property of these vortexes is that the...

Why are gambling odds for things like boxing matches considered to be accurate?	[ "The bookmaker doesn't care that they have accurate odds, they care that they make money no matter who wins the fight.

They have technical schools if you just want to specifically learn a craft or trade and not worry about genera...	[ "The airlines want to be able to fill every seat.
