I'm basically through with the AP Calculus BC curriculum, and I think I have a good grasp on calculus as a set of tools. However, I don't think I've got a great grasp on calculus as a concept [we haven't done any proofs this year and I know very very little about Delta-Epsilon proofs.] I was looking at this book to work on over the summer; opinions? https://www.amazon.com/Elementary-A...=sr_1_1?ie=UTF8&s=books&qid=1272683362&sr=1-1 Actually, while I'm at it, I may as well ask for a recommendation for a book for someone who's finished the AP Physics B curriculum. I'm more interested in particle physics and quantum mechanics than kinematics, but I understand that those fields require some things I probably don't know. That said, any book recommendations to start me off?
