Hello all! So, I'll be taking first-semester quantum mechanics and partial differential equations this fall, and would like to get a little bit of a head start by reading/working some problems on my own this summer. After some initial browsing, I've heard mixed-to-poor reviews concerning Griffiths for quantum, but I'm really not sure where to start; I'm looking for a nice accessible textbook that would be quite readable and not unnecessarily rigorous after one semester each of E&M and modern physics. And I have no idea which PDE texts would be good for self-study, so... (I took ODEs about a year ago, as well, but nothing more since then.) The topology aspect is more independent interest, as I won't be able to take any sort of class on it until next spring or so at the earliest. However, having real analysis and abstract algebra courses under my belt, I think I would like to scope topology out a bit too. Any book recommendations for any of the three subjects would be greatly appreciated! :) P.S. Has anyone read Griffiths on Elementary Particle Physics? If so, what did you think? That's a book I've been wanting to check out for a while too.
