Methods of Mathematical Physics Vol I 1937

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.
