Thorough, extremely useful treatment of classical mechanics, electromagnetic theory, and relativity, includes full explanations of function theory, vectors, matrices, dyadics, tensors, partial differential equations, and other advanced mathematical techniques. Nearly 200 problems with answers from many different fields of physics and varying widely in difficulty.
Excellent reference/supplement to nearly all of my classes from undergrad. I came upon it by accident - the physics library was tossing out "old" books and I grabbed this before it went in the trash. Glad I did!
