I finished the two semester calculus based physics sequence (using Halliday, Resnick, and Walker) at my school last semester as well as the three semester calculus sequence (although we didn't cover line and surface integrals or the theorems of Green and Stokes so I had to learn that on my own). I am currently working through An Introduction to Mechanics by Kleppner and Kolenkow, Electricity and Magnetism by Purcell and Morin, and Mathematical Methods in the Physical Sciences by Boas. I'd like to study classical mechanics but I don't know what book(s) would be suitable. Perhaps Taylor, Morin, or Goldstein? For electrodynamics what would be the next step up? Is Jackson too big of a jump from Purcell and Morin? Is Griffiths more appropriate? When I'm ready for Jackson, are there any alternatives to think about or is it the only choice for its level? What's a good book for learning quantum mechanics after classical mechanics? Should I start with a book like Shankar's then move on to Sakurai or Merzbacher? Sorry if this is too many questions. Maybe I'm getting ahead of myself, I've just been doing a lot of reading to try to figure which books to buy and I'm having a hard time figuring out what kind of progression is reasonable.
