a good math physics book might be a good idea too. Boas is the one I used as an undergrad. I liked it well enough. It does a decent job introducing the calculus of variations, and introduces tensor forms and a bit of differential geometry and has some good application problems.

ok so I understand the general idea of Emmy Noether's theorems, for every differentiable continuous symmetry there is a correlated conservation. The classical formulation seems simple enough, but the field theory formulation seems nasty. I have been through electrodynamics and quantum...
