Hello! I've been researching hygroscopic materials and evaporation rate a bit lately, and a question has struck me which I haven't found an answer to yet: What material factors affect the rate of evaporation? Is it possible to engineer a material which is hygroscopic (absorbs water) in humid...

Thanks a lot for the answers, they made it a lot clearer.

Hello! I have recently been looking into the phenomenon of gyroscopic precession in my free time, and there is a scenario which I am not sure I have fully understood. Here it is: Imagine a bicycle wheel with a shaft running through it's center. The shaft is attached to a rope at one of it's...

Thank you for the informative answer, it helped me a lot in understanding this issue. You explained very well how the anti-proton acquires its negative charge, but my question still remains if you take it one step further to why the anti-up quarks has their negative charge, but I guess this...

I don't mean to offend either of you, but all of this sounds to me that we just haven't found out why yet, and the only explanation that we have so far is that "It just is that way, don't ask about it". You say that the electron has the negative charge, and that it's a basic part of nature. My...

Hello I am aware of what generates the electric charge of each particle, the virtual fotons around it that the particle generates, and that when two particle interact with each other a foton is exchanged and so forth. My question is though, what generates the positive and negative charge, and...

Thanks for the reply! What are all the quantum numbers? Is position and momentum part of those? And if so, is that why the K-shell only has two electrons, because it is so tight that they have the same position value (or quantum number) and therefore only can have two "ways to be different", and...

Hello! From what I have understood, there are two different states that an electron can have (Spin up and spin down), and if two electrons are in the same state their wavefunction collapse. So far so good. In a video I saw, they claimed that because of this, only two electrons can exist in the...

What about spacetime? Isn't that "space itself"? Space can bend, so it has to be something?

Wow, thanks for all the replies, it really helped me understand relativity better! I have another question. Let's imagine you could remove all matter and all things in the universe, so that only space itself would have been left. If only I, my body, existed in the universe, would speed exist...

Oh then I get it. Thank you!

But if nothing can have a speed without comparing it with something else, how does the effects of approaching c affect the object? For example, the room is contracted a lot when moving fast, but if you need something to move relative to, I could perhaps say that I am moving at 0.99 of c relative...

Hello. I have been studying a lot of physics on my own through the internet (I am 16 years old, I intend to keep studying physics when I get older), and I get the most of Einstein's theories and quite a lot of the quantum mechanics, but there is something I don't understand about special...
