Can anyone recommend an introductory general Astrophysics text for a senior physics undergrad? I'm looking for something that has at least a moderate amount of mathematical examples, and is heavy on exposition (even ad nauseum). I like textbooks that include some history of the subject, for example, a book that explains where equations come from, as opposed to just spewing them out at the reader. I also tend to prefer the writing style that can be found in books written by the OG scientists (i.e. Maxwell, Planck, etc.). Thanks a lot.
