　　《黎曼几何》非常值得一读。

内容简介

　　The object of this book is to familiarize the reader with the basic language of and some fundamental theorems in Riemannian Geometry. To avoid referring to previous knowledge of differentiable manifolds， we include Chapter 0， which contains those concepts and results on differentiable manifolds which are used in an essential way in the rest of the book。
　　The first four chapters of the book present the basic concepts of Riemannian Geometry (Riemannian metrics， Riemannian connections， geodesics and curvature). A good part of the study of Riemannian Geometry consists of understanding the relationship between geodesics and curvature. Jacobi fields， an essential tool for this understanding， are introduced in Chapter 5. In Chapter 6 we introduce the second fundamental form associated with an isometric immersion， and prove a generalization of the Theorem Egregium of Gauss. This allows us to relate the notion of curvature in Riemannian manifolds to the classical concept of Gaussian curvature for surfaces。

好书，值得

在这本书里我看见当年大批意气风发的文青、艺青散落在各地，青春和国家对他们而言都已成为一个空洞的字眼。再者，我读着他们写下的诗与文字，那股偏执而热浓郁的情感由于无处喷薄而变得更加炽烈，在地下奔走。这股炽烈最终指向了那个确定的靶子。

　　虽则李敖惯于吹捧，此戏剧性人格，亦这个时代读书人的生存之道，不想苛求。但大多数既称学者，又谓作家，还兼任公共知识分子的。进一步说，我对这些还是感到怀疑。

很好的一本书，就是有点老了
