I see a lot of talk about QM, relativity, particle physics, classical mechanics, electrodynamics, etc. But I hardly see statistical mechanics (or pure thermodynamics, for that matter) related matters, beyond the pure basics, that is. What's the reason for this? Is it perceived to be less interesting? Less relevant? Or is it simply a very specific niche, in the sense that it is not regarded as 'large'? Or is there something else? The most rare of all seems to be non-equilibrium statistical mechanics. Given, there's not an encompassing theory yet, but a lot of interesting yet accessible work has been done on it, certainly at the level of a PF post. My own guess: statistical mechanics doesn't seem to be an important part of the curriculum and hence nearly all physicists know no more than its basics, hence there's little to talk about, or if there's a post about it, it doesn't get a lot of attention since not a lot of people would know the answer. This post is not as much as an attempt at propaganda as me just being curious for what the reason is (or is my perception wrong?).
