I am taking a course on modern physics, and I want to get a textbook to help me out because nothing my teacher has given my class to work with has problems. They're all explanations that aren't even all that helpful (not many graphs/pictures, just words). I'm sick of it because I have nothing to test myself with, and I'm just sick of reading like I would for a history class or something. Any suggestions for a book that has good (i.e. thought provoking) problems and visual explanations? Edit: Also, I am looking for a book on exclusively modern physics, not a textbook "with modern physics".
