这是一部东巴文化研究的论著。这是一部探索和解读东巴经典——英雄史诗《董埃术埃》的专著。用二十多万字的一本著作来论述、解读一部东巴经典，这在东巴文化的研究史上是一次创举，是使人耳目一新的一次开创性研究。

当今社会，对高素质人才的需求日益迫切。相应地，在学校中，注重素质教育，已成为人们的共识，在社会上，不断提高自身素质，已成为每位走向成功或更大成功人士的追求。一个人的素质有多方面，但数学素质，即智力素质，无疑是一个十分重要的方面。我们在学校里学的数学，作为一门学科，总包括两个方面：一是知识，一是能力。能力，即数学思维能力，与智力素质有着较为直接的联系。在学校里，进行数学思维训练的手段是做数学习题，这些习题以数学知识为材料，这当然是很自然合理的，因为教育的目的之一就是传授知识。但仅从训练思维的角度出发，还可以有一种以五光十色的社会生活为材料的数学趣题。这种数学趣题，并不涉及较深的数学知识，却要求有较强的思维能力，用来在课余或业余进行思维训练，是再恰当不过了。《数学思维游戏》中用于解题的数学知识一般不超出初中范围，题目的编排大致上是从易到难。当然，难易不是绝对的，况且有些题目因其中故事内容的关系，难易顺序也有颠倒。答案中有些内容比较深，可以先放一放，日后再加琢磨。一旦弄懂，必定其乐无穷，说不定还会由此把你引入数学殿堂呢！

This monograph is a comprehensive survey of the results obtained on the geometry of classical groups over finite fields mainly in the 1960s and early 1990s.For the convenience of the readers I start with the affine geometry and projective geometry over finite fields in Chapters 1 and 2， respectively. Among other things， the affine classification of quadrics is included in Chapter 1， and conics and ovals are studied in detail in Chapter 2. From Chapter 3 and onwards the geometries of symplectic， pseudo-symplectic， unitary， and orthogonal groups are studied in succession. The book ends with two appendices， on the axiomatic projective geometry， and on polar spaces and finite generalized quadrangles， respectively. Now I shall say a few words about the problems we are going to study in Chapters 3-7， and in addition give some historical remarks.

斯梅尔是1966年菲尔兹数学大奖得主，他是一位有着独特人生经历的当代数学大师。他在数学的许多领域中做出了卓越成就，例如首先证明将球体从内向外翻转在理论上是可能的，提出了混沌概念的先声——斯梅尔马蹄等等。斯梅尔首先突破了维数障碍，在高维宠加莱猜想上取得重大进展，证明一个六维的世界有可能比一个三维世界更为简单。不仅如此，斯梅尔还是一名发起了旨在终结越南战争的反战运动的狐胆骑侠，并与美国的科学管理机构进行过维护学术自由的不懈斗争。斯梅尔有丰富的业余爱好，不但被公认为顶级的矿石收藏家，而且还热衷于摄影、航海、登山。本书由一位十分熟悉他的数学家撰写，不但以极其通俗的语言，介绍了斯梅尔数学成就的迷人之处，更令我们看到了一个特立独行、勇于追求、执着探索的数学家形象。...
