I'm looking for some good book recomendations for the basics of quantum mechanics. I have a decent amount of calculus, and have even taken a course on QM, though that was like 16 years ago. This is not for a course, just for my own interest. I have a good basic understanding of physics in general, but am rusty on actually working through problems, and have forgotten some of the more complex terminology. I read QED by Feynman with no problems, and then started reading Quantum Field Theory in a Nutshell by A. Zee and realized my background was too vague to follow it as much as I'd like ... the problems were mostly with the notations, some of the terminology, and formulaes the reader was assumed to be overly familiar with. So I want to read something that will give me the base I need to read the Zee book. Any recomendations would be appreciated.
