This textbook takes an innovative approach to the teaching of classical mechanics, emphasizing the development of general but practical intellectual tools to support the analysis of nonlinear Hamiltonian systems. The development is organized around a progressively more sophisticated analysis of particular natural systems and weaves examples throughout the presentation. Explorations of phenomena such as transitions to chaos, nonlinear resonances, and resonance overlap to help the student to develop appropriate analytic tools for understanding. Computational algorithms communicate methods used in the analysis of dynamical phenomena. Expressing the methods of mechanics in a computer language forces them to be unambiguous and computationally effective. Once formalized as a procedure, a mathematical idea also becomes a tool that can be used directly to compute results.The student actively explores the motion of systems through computer simulation and experiment. This active exploration is extended to the mathematics. The requirement that the computer be able to interpret any expression provides strict and immediate feedback as to whether an expression is correctly formulated. The interaction with the computer uncovers and corrects many deficiencies in understanding.

Feynman et al,Thees are the lectures in physics that I gave last year and the year before to the freshman and sophomore classes at Caltech.The lectures are,of course,not verbatim-they have been edited,sometimes extensively and sometimes lessso.The lectures form only part of the complete courese.The whole group of 180students gathered in a big lecture room twice a week to hear these lectres and then they broke up into small groups of 15 to 20 students in recitation sections under the guidance of a teaching assistant.In addition,there was a laboratory session once a week. 此书为英文版。

Devoted 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.

In this edition the book has been considerably augmented and revised,with the assistance of L.P.Potaevskil throughout. New xections have been added on the magnetic properties of gases,the thermodynamics of a degenerate plasma,liquid crystals,the fluctuation theory of phase transitions of the second kind,and critical phenomena.…… 　　此书为英文版。
