It's crazy that we don't have a physics general.
I'm noticing by looking at the catalogue that there's quite a few meaningful threads, I remember things being much worse, so I suggest we keep this momentum going.
Let's keep this thread alive, it's gonna pay off.
Cause when educated people have no threads here to post in, they just leave and then we all lose.
I'll start with a question. It says in a QM textbook (as an illustration of how much information you need to know about classical systems vs quantum ones) that for a classical system you'll need 6*K digits (3 momentum and 3 position coordinates and K digits for each), while for a quantum you'll need L^3*2K (K digits for real and imaginary part of the wave function), where L^3 is the quantity of knots (this may be an incorrect term since I'm translating from Russian but hopefully you know what I mean) in the lattice LxLxL. So the question is: what is this lattice they are talking about?
