Hi, I'm trying to learn physics and math on my own (I'm 16, bored with what I'm taught in school, and on vacation right now, so I have some free time). Over the past 4 months or so I've started more seriously learning, and I think I've been doing fairly well. To learn mechanics, I've been using An Introduction to Mechanics by Kleppner and Kolenkow (which is amazing, even though the end-of-the-chapter problems are sometimes extremely hard) and I've consulted the Feynman Lectures on Physics for extra insight or if I am confused. I've also been watching Walter Lewin's lectures on MIT Opencourseware, and they're pretty good. To learn calculus, I read Calculus Made Easy by Thompson, I watched a lot of Khan Academy, and I recently started studying from Differential and Integral Calculus by Courant (which is the most in-depth look at math I have ever seen, and I've loved it. It is a completely different world from how math is taught in high school, and it took some getting used to, but I think the hard work has been worth it). I was wondering if anyone could recommend a (or some) textbooks or resources to learn electrodynamics from. Also, I sort of know multivariable calculus, but I want to get into it more deeply, particularly vector analysis (which I have to do if I'm gonna start learning about electrodynamics). I'm thinking of getting the second volume of Differential and Integral Calculus, but if anyone could recommend more things that would be great. Thanks very much for your help. PS. I feel like I'm understanding everything I'm learning and I'm pretty confident that I'm learning everything correctly and from pretty good sources. However, I'm not completely sure, and if anybody has any ideas on anything I could be doing better, that would be greatly appreciated.
