I'm in grad school for systems/control engineering. I'm much more interested in the theoretical aspects of the subject as opposed to building physical systems. Maybe that makes me less employable, but regardless, a lot of my ideas now require the mathematics developed mainly in thermo/stat mech, but my EE undergrad degree doesn't really prepare me from the thermal physics/stat mech material very well, And I doubt I could be permitted to take a thermal physics undergraduate course even if for the sake of research. I have statistical mechanics textbooks, both of which appear to be written Well, but I do not seem to have the thermal physics prerequisite material. In addition, most of the "schaums teach yourself thermodyanamics" are more geared towards engineering, which means steam tables and physical systems, as opposed to the mathematical methods and content which is useful to me. So the question is, how do I study thermal physics (and ultimately stat. mech) on my own? I'm very comfortable with self-study, but I'm also aware that without the right resources, it can be nearly impossible. I'm looking for recommendations on video lectures (if you know any that exist), practice problems with answers (so i can check my work), readable textbooks, etc. That go into the deep mathematics of the subject as opposed to preparing me for the trade. Thanks for reading!
