MechanicsDevoted to the foundation of mechanics, namely classical Newtonian mechanics, the subject is based mainly on Galileo's principle of relativity and Hamilton's principle of least action. The exposition is simple and leads to the most complete direct means of solving problems in mechanics. The final sections on adiabatic invariants have been revised and augmented. In addition a short biography of L D Landau has been inserted.

User Review  Joecolelife  GoodreadsThis book blew my mind when I first started to read it. Let me start by saying this may not be my first suggestion of a book to start with if you know nothing about classical mechanics. But once you ... Read full review
