介绍数学物理联系的一本好书，推荐给大家，希望对大家有所帮助

comment copied from amazon 2001: I brought this book ( volume 2 also as well ) because of its " fame ", but when I read it, it has several draw backs. First, may be the original version is in German, so even with good translation, it seem does not fit in the usual English style we get used to. Also the topics it choose is too few and also the area covered is too narrow and not well co-ordinated. For example, the whole volume I is almost dedicated to Calculus of variation only. In volume 2, the whole book is dedicated to differential equations. But that is not the greatest drawback. The most bad point is that the book just presents formulae after formulae, equations after equations, without giving examples of how to use it, and also no exercise for me to practice.

2nd edition translated by McShane, E. J. 这是柯朗原来德文原著的1937的英文版，与1989 Courant and Fritz John 版 (Introduction to Calculus and Analysis Volume One) 不同之处是这个带答案的。

Courant, Hilbert - Methods of Mathematical Physics Vol. 1 这是Courant, Hilbert 著 数学物理方法的中文第一卷。非常的好。
