　　《黎曼幾何》非常值得一讀。

內容簡介

　　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。

　　二十七歲的李敖曾在《十三年和十三月》中說過一段話：

　　中國當下的文藝界似乎都有喜談政治的傾嚮，我謂之“多重身份化的綁架”。說來這本是題中之義，但又似乎許多人已經習慣瞭這種綁架，甚至於頗為享受。理智一旦不能掌控私欲，可信力自然也就發生崩坍。“中國士流嚮來看重政治，從事文化工作者往往心不專一，覺得弄政治更為有效，逐漸的轉移過去瞭。其實文化工作者不必看輕政治，隻應把自己的事業看作與政治一樣重要，或者如有必要即認為也是一種政治的工作亦可，專精持久的做去，效果自會發生齣來。”周作人的這句話雖稍顯理想，但我最同意。
