He excellent critique and fairly positive response to the first edition of this book have encouraged me to prepare this second edition. I was greatly helped by suggestions from colleagues and students. Meanwhile we have profited from our experience in teaching the course. In particular I would like to mention my colleague Professor Wang Xu who has taught the course with me for years and contributed a lot to the improvement of the book and the teaching. In this edition I have tried to make improvement whatever possible. We have corrected all mistakes and typos ever discovered. Many paragraphs have been rewritten to make them more accurate, understandable and neat. Following a widespread request, I have put the answers to the odd-numbered problems at the end of the book. Appendix A, Commonly Used Physical Constants, has been renewed to ?1998 recommended values?. Throughout this edition those constants are all tuned to new values. Users may find that this is an introductory textbook for pedagogical purpose, yet it provides reliable references. Some recent progress in research of frontier topics has been mentioned. Several new references are added. Most figures are treated again to make them clearer, better, and more helpful. I would like to express my sincere appreciation to Editor Kaifei Hu who did an impossibly careful job of proofreading, making my preparation of the manuscript a pleasant task.
