内容简介

This volume covers approximately the amount of point-set topology that a student who does not intend to specialize in the field should nevertheless know.This is not a whole lot， and in condensed form would occupy perhaps only a small booklet. Our aim， however， was not economy of words， but a lively presentation of the ideas involved， an appeal to intuition in both the immediate and the higher meanings.

The book I've surveyed which includes Janich's Intro to Differential Topology, Isham's Differential Geometry for Physicists, Differential Manifold by Serge Lang, Introduction to Manifolds by Tu L.W. unfortunately all reads like books written by mathematicians for mathematicians and has a dearth of physical examples and visual aids. Tu L.W.'s Intro to Manifold is surprisingly soft handed and perhaps would be good for a first book. The book nonetheless lacks motivating examples and il

有关拓扑学的一些内容早在十八世纪就出现了。那时候发现一些孤立的问题，后来在拓扑学的形成中占着重要的地位。譬如哥尼斯堡七桥问题、多面体的欧拉定理、四色问题等都是拓扑学发展史的重要问题。 七桥问题 主条目：七桥问题 哥尼斯堡七桥问题 哥尼斯堡是东普鲁士的首都，普莱格尔河横贯其中。十八世纪在这条河上建有七座桥，将河中间的两个岛和河岸联结起来。一天有人提出：能不能每座桥都只走一遍，最后又回到原来的位置。这个看起来很简单又很有趣的问题吸引了大家，很多人在尝试各种各样的走法，但谁也没有做到。 1736年，有人带着这个问题找到了当时的大数学家欧拉，欧拉经过一番思考，很快就用一种独特的方法给出了解答。这是拓扑学的“先声”。[1] 欧拉定理 拓扑学 在拓扑学的发展历史中，还有一个著名而且重要的关于多面体的定理也和欧拉有关。
