comment How to deal with the notation of a function $f$ vs its value $f(x)$ in Physics?
Are you familiar with the implicit function theorem? Many of the "functions" you describe are probably better understood by mathematicians as relations, which can be converted locally into functions via this if you need to do so.

comment How deep can my knowledge of particle physics go without the maths?
"Physics, by definition, is the subset of Mathematics which pertains to our universe." I disagree with this. There's plenty more to physics than just pure math. I tend to agree more with Vladimir Arnold that the containment is in the other direction: "Mathematics is a part of physics. Physics is an experimental science, a part of natural science. Mathematics is the part of physics where experiments are cheap."

comment What are the physical dimensions (units) of the elements in a Hilbert space of a QM system?
@REX Thanks for catching that. I've now corrected it. I make silly typos like that all the time.

comment What are the justifying foundations of statistical mechanics without appealing to the ergodic hypothesis?
@josephf.johnson As for your answer, I haven't yet had a chance to read it, unfortunately. This question has not had any activity for the better part of a year, and the answers do a pretty good job at least at the level I was looking for, so to be honest I had totally forgotten about it. Your answer seems to be at a more advanced level and does explain things in more detail. I appreciate it, even if I don't get a chance to look at it any time soon.
