Electricity & Magnetism, Thermo + Quantum Mechanics? Hi! I've recently completed my first semester of college and it's offered me some insights. For example.... the world is three-dimensional and, as such, multidimensional calculus exists! I managed to somehow survive Honors Mechanics but it made me realize something: I don't know jack about Physics or Math. Anywho, right now I really want to tackle on EM (Purcell), Thermo (Giancoli or Resnick-Halliday-Krane) & QM (Griffiths). From the looks of it, it seems like EM requires Multi, Lin Alg & Diff EQs. If anyone would like to add onto the list, please do. As for QM & Thermo, I have the following questions: What Physics/Math background should I build up before learning QM? For Thermo? Is it appropriate to do EM & QM simultaneously? Can the Oxtoby's Principle of Modern Chemistry enrich the study of QM and/or Thermo, or would it simply be redundant? My background: Honors Mechanics + Waves. (Kleppner & Kolenkow + AP French) We didn't get to covering Non-Inertial Frames, Relativity or Fluid Dynamics and the treatment of Waves was really poor. Multivariable Calculus (Stewart). It was a mellow introduction (which isn't bad given how difficult it was for me to grapple with Physics that semester...) but certainly not rigorous. My professor recommended Spivak. Some basic Lin. Algebra (computational, not theoretical) but I don't have much basis in Diff EQs beyond a really hazy recollection of high school AP Calc curriculum. Next semester, I'll be taking Diff EQs (Nagle-Snaff-Snider) & Lin Alg (Lay). I'll probably supplement Lin Alg with Axler's Linear Algebra, Done Right. Any critiques or suggestions?
