If approx. 80% of dust is dead human skin cells, how does dust collect in a long-empty house? | According to QI the 80% thing is just a myth. *This is one of those “Eww!

But, most would argue he shouldn't serve the same... |

The Austrian School of Economics. | Haha that stuff is well beyond ELI5. Honestly I doubt a lot of people with tertiary degrees in commerce would understand all the concepts used in those paras.

Why haven't we come up with an easier way to get to the top of Mount Everest? | The reason they want to go there is *because* it is dangerous and difficult and life threatening.

Making it easier would ... |
Why don't computers drive trains, instead of people? | There are a number of train systems around the world which are completely computer-driven, one well-known one is the [Docklands Light Railway] system in London.

Why does sports tape help get rid of pain? | First my physiotherapist told me there IS actually something in the tape but it isn't a painkiller, it is a substance that penetrates the skin and helps contracted muscles relax.

If I don't digest a seed (flax, chia, sesame) do I get any nutritional benefit out of it? | The gastrointestinal tract essentially makes the human body an elongated doughnut.

How Mathematicians can figure out when an extremely large number is prime or not? (E.G. 2^[57885161]-1) | For a very large number, such as your example, there isn't enough computing power in the world to divide by every single prime number that's smaller than it . We resort to other primality tests to test very large numbers for primality. The primality test that has been used to find the largest known primes so far is cal... |
If I drink half of a 5 Hour Energy, will I only get 2.5 hours of energy out of the deal. Or will I get 5 hours of 1/2 energy strength? | You will get 5 hours of half strength. *Most of the time* including this case, dosage does not affect metabolic rate.

Those are two different types of receptors that bind very different chemicals. If the spice doesn't b... |
What do capacitors do? | Capacitors store charge. It's basically two plates so close together separated by a insulator. Electrons can build up on one side and come off the other plate without any actually moving through the insulator. This happens because they build up on one plate and move off the other plate. The plates are so close the extr... |
If sodium is so unhealthy, why is salt an appealing flavor? | Sodium is not inherently unhealthy. In fact, it's *necessary* for us to survive. The problem is *too much* sodium. So the reason that we like it is the same reason that fat and sugar taste appealing: We evolved in an environment of scarcity, where, if we came across one of these things, we *really* needed to consume th... |
Why can't DirecTV deliver internet access but flawless streams of HD video? | There are three major issues you face with satellite internet connectivity that you don't face with other types of connections . 1) Standard satellite dish installations are designed for receive-only communications. You typically need special hardware installed at the customer's home in order to facilitate two-way sate... |
Why are truly random numbers significantly advantageous to pseudorandom numbers? | That part about selling random numbers online was a joke. Hardware RNGs are cheap, and having someone else generate your random numbers and send them over the internet would defeat the purpose of having secure RNG in the first place. Good pseudo random generators produce a sequence of numbers that is not in practice di... |
How do competitors receive seemingly specific scores in judged sports such as figure skating? | I think many sports start out with the perfect score of 10, and then deduct small points for any mistakes they see. For ice skating for example maybe they landed there tripleaxel jump but only went around 2.8 times instead of the full 3, or there spin was wobbly , or they almost fell . Or they did fall . And routines n... |

My Suitemate is blasting bass on his subwoofer to ungodly levels. I tried recording it from my room on my iPhone but it didn't record anything. Why? | Because those frequencies are either too low for the microphone on your phone to pick up, OR it DID record, but the tiny speaker in your phone is too small to play frequencies that low.Are you trying to play back the noise made by, say, a 10 inch diameter subwoofer on a phone with a speaker that's not even 10 *millimet... |

From where do we get our helium (from the atmosphere / from mining), and through which industral process? | Commercial Helium is extracted from Natural gas Helium collects underground, possibly as the result of the radioactive decay of Thorium and Uranium.

Having the fans be tied into the lights so that the fans are always running when the lights are on means that the hotel owners have a reasonable expectation that i... |
How a CPU can bottleneck a GPU, and how to tell if this is happening | A GPU is only useful for rendering graphics. The CPU is responsible for handling AI, the state of the game world, physics and all that jazz.

how does South Park get to say "any likenesses or similarities to real people or events are purely coincidental" when their entire model is making fun of current (real) events and people? | It's a joke, not a legal disclaimer. Parody and satire are protected by law, so they're allowed to make fun of whoever they want. It's confusing because libel is illegal. You're not legally allowed to try to defame someone by lying about them. For example, if I wrote a news article that claims that Rush Limbaugh eats b... |
the relationship between magnetism and electricity | The electric and magnetic forces are actually two manifestations of the same thing. For simplicity's sake, let's just say that magnetic fields are caused by moving charges . Electric fields are caused by charges regardless of whether or not they're moving. So let's imagine a situation where I'm holding a charged object... |
Why does the body vomit when spatially disoriented? What benefit is there from losing your lunch when the floor is moving? | The sensation of "motion sickness" is really just your brain getting conflicting information from your sense of sight and your sense of balance.

What reps f''(x) represent? | A practical example for this is the location, speed and acceleration of an object. If you have an object that can move along x then it's position is f .

Why is it necessary for batteries to be inserted with the ends opposite each other? | It takes less wiring that way. The batteries are being used in 'series' - like in a flashlight where the top of the second one goes in up against the bottom of the first one.

Also, higher resolution means higher processor usage. |
Why do some people (especially online) get abusive/insulting when they get rejected? | It's a defense mechanism.

Why do planes, when starting to takeoff, seem to throttle up slightly for a few seconds then go full power? | During the few seconds at partial power, the pilots will be confirming that the engines are operating normally - and, most importantly, they've had enough time to stabilise so they are both/all generating the same power - and ensuring that the aircraft is rolling in a straight line down the runway. Then they will apply... |

Why Exxon is not punished for choosing to keep a secret like climate change, which has an impact for everyone on the planet. | Because making destroying the earth atmosphere isn't illegal. There's no universal law that says you have to be good to mother nature.For them to be punished, they would have to be charged with a crime and/or sued in civil court. The charge/suit would then have to be proven. This is a long, drawn-out process, so it can... |
Why do people in shows slip on banana peels? | Originally, it was supposed to be a reference to slipping on animal crap From there, it kind of became a thing of its own.This doesn't need to be verbally explained.
