The title says it all, one time my friend got really high and he couldn't sleep because he couldn't find a definite answer to this question.

If the moon causes high and low tide due its gravitational forces, does the sun also cause its own variation of high and low tide as well?

Why is iodine used as a disinfectant? I've looked for information online but several articles say its "unknown." Why is iodine a good disinfectant?

Could you actually fall into a black hole ?

Posted: 09 Feb 2020 12:13 PM PST

As I understand it, time goes faster and faster (in your reference frame) as you approach the speed of light (in the black hole's reference frame) when falling into a black hole, until it eventually gets infinitely fast. But thanks to Hawkins radiation black holes have finite lifespans, so woudn't the black hole die before you reach its event horizon ?

Do neurons push or pull signals?

Posted: 09 Feb 2020 07:33 PM PST

When computers talk they either push or pull. Pushing is when a computer sends a message to the other (notifications) and pulling is when a computer asks another computer for the message (refreshing your inbox or checking the weather).

Do neurons push messages to each other, pull messages, or both?

Are modern day lenses for glasses (the kind you wear) still made of actual glass, or are they plastic now? If they’re made of plastic, how can they correct vision as effectively as actual glass lenses?

What is Martian soil like? Is there more than one kind, like on Earth?

I saw today's SMBC comic, and it got me wondering--could you actually make clay on Mars? I know clay is a specific type of soil--is earth of that kind found on places other than, well... Earth?

Why does light slow down in medium?

Posted: 09 Feb 2020 04:42 PM PST

The usual explanation I heard is "light bounces back and forth between atoms of the medium, effectively slowing down". But that cannot be the correct explanation, because it is purely corpuscular. Slowing down in a medium must have a wave explanation, because it causes refraction on boundaries between different media, and refraction is purely wave phenomenon.

How are cluster/massively parallel computers applied to solve problems in pure mathematics?

Posted: 09 Feb 2020 07:33 AM PST

All the work I have done on clusters has been related to informatics. For example, I might get a huge dataset and process it in parallel to get the job done faster. It makes sense to me why clusters are used for hyperparameter searching neural networks or doing molecular dynamics. Are clusters commonly used to do mathematics research, perhaps in the form of computer aided proofs?

What determines the power of a radio transmitter? What is it in big commercial transmitters that makes them radiate more power than tiny DIY transmitters? Is it the antenna size? The operating voltage? What would you need to change in a transmitter circuit to make it radiate more power?
