Good physics books

I recently acquired some good physics books. Best among them:

Mathematical Methods for Physicists, Arfken and Weber

An outstanding text for undergraduate and early graduate physics math. Particularly useful are the problem sets and the emphasis on physics applications.

A Modern Introduction to Particle Physics, Fayyazuddin and Riazuddin

Putting the use of articles aside (Pakistani English isn't exactly the same as American), the writing is direct, very clear and to the point. This is a great text to read through and research interesting points on the side as you go along.

I really enjoy summer reading.
