A fine introduction to classical mechanics. Don't be downhearted, the Lagrangian and Hamiltonian views of mechanics in fact serve to simplify and systematize the subject. They provide general methods for expressing and solving mechanics problems, where the usual freshman physics methods require you to figure out a new approach for every problem. Also, they are the only way to approach quantum mechanics so that you'll understand it. Another, shorter book with an introduction to this material and other ideas on a beginning level is "The Six Core Theories of Modern Physics," by Charles Stevens. One great thing about these books is that you can leave them laying around in public places, and nobody will steal them.
