*Mathematical Physics*, Dover press, ISBN 0-486-60056-4. This reference has a very nice discussion of dyads and how to express classical mechanics in tensor form, which is actually quite lovely. - Fabulous complex variable/contour integration reference by Mark

This online lecture note/book actually works through the Euler-Lagrange equation as well, but stops unfortunately short of doing EVERYTHING that we need in this course. It is only 70 pages, though - probably unfinished. - Introduction to tensors by Joseph C. Kolecki at NASA:

http://www.wikipedia.org Wikipedia now contains some*excellent*articles on real graduate-level electrodynamics, relativity theory, and more. The math and science community are determined to make it a one stop shop for supporting all sorts of coursework. - Mathworld:

http://mathworld.wolfram.com This site, too, is very good although some of the articles tend to be either then or overly technical at the expense of clarity. - GIYF
