The answer by @Nugatory is incorrect. As suggested by @anuttarasammyak, experiments with muonic atoms show that bound particles do...

This would happen whenever your stability condition (acyclicity?) forces the transitive closure of your general binary relation ##R\,##...

Are you sure you are in the right frame of mind to learn relativity?

@jack action Look for simulated annealing (SA) algorithms and search for their applications if you are not familiar, it may give you...

@Amazed, could please stop telling me, and other physicists, how to do, understand and think about physics? You don't go to surgeons and...

Really? In post #1, @Vincf obtained: $$E_y(r_1, r_2) =- \frac{\sigma}{2\pi\varepsilon_0}\ln\left(\frac{r_2}{r_1}\right)$$ where ##r_1...

I interpret the standard result for the uniformly charged infinite plane as follows. If we have a large uniformly charged plate, then...

I’m not asking whether partial orders can model spacetime (as in causal sets), but whether they can emerge from non-order relations ?

So, can you specify by what you mean by "something more primitive" than Szekeres' signal relation S which "is reflexive, but not...

It's a good idea to work this out for yourself. Take two particles of different masses at rest relative to each other. Release them and...

Potential energy is generally a function of the position of all particles in the system.

This is why in the development of the Riemann integral, you need an sequence of upper bounds and a sequence of lower bounds that...

I think it similar to the proof that pi=4 in the video below at 1:39. The explanation at 15:09 points out the fallacy @PeroK mentions above.

The idea is that you have a right triangle with two unit sides. Shape n has n equal horizontal steps and n equal vertical steps instead...

Even better would be to first study physics and then to realize that thinking about philosophical categories such as matter is...
