Problems in dynamics have fascinated physical scientists （and mankind in general） for thousands of years. Notable among such problems are those of celestial mechanics， especially the study of the motions of the bodies in the solar system. Newton's attempts to understand and model their observed motions incorporated Kepler's laws and led to his development of the calculus. With this the study of models of dynamical problems as differential equations began.本书为英文版。

This book， a companion volume to Electronic Structure and Chemical Bonding （World Scientific， 1996）， is concerned with the teaching of optical spectroscopies of electronic absorption. It is the culmination of about ten years of experience in the teaching of the subject and the training of students to become teachers in the physical sciences.　The book covers topics of current research and includes about 30 problems with solutions， most of which are adapted from tests proposed recently at the "Aggregation" in chemistry and physics. It provides as much coverage of elementary quantum mechanics， group theory and the electronic structure of molecules as is necessary for the reader to understand the rest of the topics. Also included are numerous appendices， often presented as charts to facilitate assimilation， as well as short bibliographies， limited to basic books and review articles.　This volume will be an invaluable guide for teachers and potential teachers in the physical sciences， and more generally for students and engineers in chemical physics and physics.

混沌理论代表了当今科学家对于世界的最新看法，它再不如牛顿认为的那样明确和有序，整个世界充满着不确定性与随机性。那么，面对着这样一个模糊的世界，我们可不可以作清晰的思考呢？这本书作出了肯定的回答。作品在详细地介绍了起源于20世纪60-80年代的混沌理论的同时，也教给了我们怎样作清晰思考的基本方法，以及如何重视全盘思考等等。书中提出的这些意见都具有相当的超前性，可以认为是属于21世纪的一种认识论。

在当今这个高科技的时代，我们可以充分享受着激光光盘带来的乐趣，享受着手机、呼机带给我们的便捷。您曾想过吗？不断涌现出的这些高科技产品与大自然中令我们赏心悦目的色彩有着共同的物质基础——色素。翻开此书，您会看到，是化学阐述了它们之间千丝万的联系。

本书着重介绍在物理学中广泛遇到的非线性方程（包括非线性常微分方程、非线性偏微分方程、非线性差分方程和函数方程）的求解（解析解）和求解方法。
