Pangea was what ... |
How can insects fall from proportionally insane heights and suffer no damage? | Put simply, if you make something twice as big, it weighs EIGHT TIMES as much.

How are interest rates for savings accounts determined? Why mine seems like it's the lowest in history ? | I believe it has to do with the rate which the Fed lends to the banks, and the rate the Fed sets for banks to lend to each other.

How come you get tired of eating the same dinner more than two days in a row but you can eat the same breakfast for years on end? | Back when the U.S. military was developing MREs, they were trying to figure out how to get troops to eat the same handful of meals over several weeks.

But that's just an average. Th... |
Why are vision problems so common in humans? | humans need glasses to see fine detail, like letters. in a hunter gatherer sense, 99% of peoples vision is probably sufficient. i suspect there are plenty of animals that would want glasses if they were intelligent enough to know they were missing out on something. but since most land animals have a highly developed se... |
If all of the cells in our bodies are replaced within a matter of years, how are tattoos permanent? | Imagine a bucket filled with ping pong balls. That's your skin.

Why we don’t generate electricity from sound waves while electricity is needed to produce a sound wave ? | We do generate electricity from sound waves. That's how a microphone works. The problem is that sound isn't powerful enough to create a enough electricity to be useful for anything other than capturing an audio signal. Even with sophisticated microphones we need to amplify the signal a lot to make it useful again.A lou... |
How does basic stock exchange work and how would one get started? | You buy a stock that's priced at $1.50 a unit, you buy 10 shares for $15 The next day it goes up to $4 a unit because there was a successful merger, they released a new product that everyone likes, etc. and you sell your 10 stocks for $40 giving you a $25 profit which you then use to buy other stocks priced low.

How did we figure out that burning rocks would make metal? | Metal working is *way* past caveman times. We figured out fire, and we figured out how to make *hot* fire . A lot of this is, necessarily, speculative, but the likely scenario is someone put some metal in a hot fire and noticed it melted. Possibly people found free-lying metal deposits, or someone had rocks with a high... |
With modern technology, why don't people get paid and billed electronically by the second or minute instead of monthly? | The technology isn't really there, or at least hasn't been developed. If you've ever worked in IT, you'd understand how hard it is to integrate different systems and make them talk to each other. Such a system would have to built from the ground up and would include real time capturing of hours worked, real time transf... |
If the computer runs on electricity, why isn't the hard-drive wiped when you turn it off? | Magnets. Basically, hard drives sorta look like a record player inside. There's a disk that spins, and a head that can move to various tracks on the disk, reading or writing.

How do we know the world is round and not flat? | If you're in the northern hemisphere, and you point your camera at the northern night sky with a long exposure, you can capture stars "spinning" around the north pole.

How come sometimes I'm able to sit down and work for hours on end, and other times I can barely look at work at all? | It's due to levels of neurotransmitters in your brain changing due to large variety of physiological, environmental, and emotional factors.

Why are many manual laborers who spend 8 hours or more a day lifting, pushing, and pulling heavy objects not in incredible shape from doing so after many months or years? | I'd say diet is the biggest factor here. A lot of those labourers/construction workers are strong as fuck but eat like shit. They'd look a lot more jacked with a healthier diet.A lot of them are. However, the balanced workout you get from doing manual labor often doesn't show as strongly as a very focused training of p... |
Why does VLC for iOS have to remove codecs like AC-3, but the desktop version doesn't have to? | Because of software patents. They can host the desktop version somewhere that doesn't recognise them , whereas due to the closed nature of the iOS ecosystem, they can't do that for that release. |
Why does unplugging plugging back in a router solve most problems? | 1. As you use a router errors slowly accumulate.

Why do we feel embarrassed when we're the only one in a group of people who laughs at something? | I suppose for the same reason doing anything out of the ordinary is naturally embarrassing, even if it's being recognized for a great honor.

Why do you see the red/green/blue lines when you move your eyes back and forth while looking at a video from a projector? | Those different color lines make the picture.

Are we lighter during the night due to centripetal force from orbit? | It would be the opposite if there is any fluctuations as at night the gravitational pull of the sun is also pulling you toward the earth while during the day the sun would be pulling you away from the earth ever so slightly.

Why do cast iron skillets make food taste better? | IMHO it has nothing to do with the oil in the pan. I have my grandmother's skillet [probably 50+ years old.] I clean it with sea salt.

How does increasing the interest rate to 17% in Russia and selling of their foreign-exchange help the Russian Ruble exchange rate ? | Selling their Euros, etc. to buy rubles means that rubles will become scarcer and the price should rise.

The first one apparently is working better than ... |

Of course, a 1" nail could just... |
How come upon walking into a room with a bad smell, at first it smells really bad, but after a few minutes, you can’t smell it anymore? | Our brains are hard wired to really only pay attention to new information. We are bombarded with a ton of stimulus at any given moment, but most of it isn't all that useful. For example, you probably didn't feel the chair you were sitting on or the shirt you were wearing until I mentioned it just now, right? That is be... |
Why in the U.S. are we not told the upfront cost of medical care so that we can shop around like we can when making any other purchase. | In a word: greed. The U.S. Health care system is a for-profit business. One tactic for maximizing profits is to obscure the true costs so as to stifle competition. Another tactic is to use fear to make a sale. What's more important than your health? To be fair, though, it's becoming more and more common, especially wit... |

How come indigenous people have historically been affected by invaders diseases but the invaders weren't affected by some random disease that the natives had? | It's not always one way.

...If aliens put a satellite into earth orbit to observe us, would we even notice with all the other satellites up there? | Yes. Astronomers carefully track all sattelites - as do some world governments. Even space junk is tracked.

NASA and other space agency's... |
