comment How are fundamental forces transmitted?
Thanks. There are sort of similar questions, but my specific question how localization and distance come into play I couldn't find (it only mentions "quantum field" without further explanation which would help me). Maybe someone can elaborate on locality in particular?

comment How do you prove $S=-\sum p\ln p$?
@Ron: I'm not saying you are wrong. I'm saying you just haven't given an answer related to the question. And I made the experience that generally people who start their answer with either "It's very easy and well known" or "I know where you are wrong" usually haven't understood the question. Feel free to check my posts word by word.

This is pretty interesting! Yet, it misses the question :( It does not answer why I should apply entropy to a system which is already completely determined by other laws. Why would I assume that a system is the max entropy distribution? One has to proof that. And it shouldn't be a hand-wavy argument either. Also the 2nd and 3rd paragraph of my question is left out. Many people claim that just everything follows entropy (black holes, life, ...). OK, so I have a particle circling another. What are p_i? What is the entropy?

The common Carnot argument wouldn't help. The question how it is supposed to be connected with all microscopic processes in general would still be as open as before. Someone must have tried that before? I know common literature but it's not in there :(; S is whatever people use for showing irreversibility.

Shannon entropy exists, but it's still no answer why it is used in physics. Shannon entropy probably has some presuppositions. So why does physics satisfy these presuppositions?
