Donald E. Knuth is known throughout the world for his pioneering work on algorithms and programming techniques, for his invention of the Tex and Metafont systems for computer typesetting, and for his prolific and influential writing. Professor Emeritus of The Art of Computer Programming at Stanford University, he currently devotes full time to the completion of these fascicles and the seven volumes to which they belong.

From the Back Cover

Nearly 30 years ago, John Horton Conway introduced a new way to construct numbers. Donald E. Knuth, in appreciation of this revolutionary system, took a week off from work on The Art of Computer Programming to write an introduction to Conway's method. Never content with the ordinary, Knuth wrote this introduction as a work of fiction--a novelette. If not a steamy romance, the book nonetheless shows how a young couple turned on to pure mathematics and found total happiness.

The book's primary aim, Knuth explains in a postscript, is not so much to teach Conway's theory as "to teach how one might go about developing such a theory." He continues: "Therefore, as the two characters in this book gradually explore and build up Conway's number system, I have recorded their false starts and frustrations as well as their good ideas. I wanted to give a reasonably faithful portrayal of the important principles, techniques, joys, passions, and philosophy of mathematics, so I wrote the story as I was actually doing the research myself."... It is an astonishing feat of legerdemain. An empty hat rests on a table made of a few axioms of standard set theory. Conway waves two simple rules in the air, then reaches into almost nothing and pulls out an infinitely rich tapestry of numbers that form a real and closed field. Every real number is surrounded by a host of new numbers that lie closer to it than any other "real" value does. The system is truly "surreal." quoted from Martin Gardner, Mathematical Magic Show, pp. 16--19

Surreal Numbers, now in its 13th printing, will appeal to anyone who might enjoy an engaging dialogue on abstract mathematical ideas, and who might wish to experience how new mathematics is created.

Winning Ways的汉译本早在2003年就由上海教育出版社出版了,名为《稳操胜券》。在后记中译者翻译成了“取胜之道”,可见译者似乎并不知道这本书有汉译。 给个链接: http://book.douban.com/subject/1082795/ (上册) http://book.douban.com/subject/1082797/ (下册) 本书...

我看这里的留言,包括书评和笔记没一个人说明白这本书到底讲了个什么,到底什么思路,整体脉络到底是什么的问题,总在扯些没用的,所以我决定留言在这里。 这本书是这样,英文名应该叫 超现实的数,其实就是说一种数论吧,原文是这样写的 他们两个发现石碑后,觉得这应该是一...

1. 译名初一看略标题党了,但看完书后觉得也算是贴切 2. 内容简介中有一句话:“本书可以看做是读懂<TAOCP>和<CMath>的钥匙" ——扯! 3. 这本书实在不能算成是一本小说,而且也不是十分有趣,所幸很短,正当我约莫有点不耐烦时,第16章就结束了,很好。 4. 翻译得挺好,几乎没...

看过英文版的,这本书从另一个新的便于常人理解的角度研究了数系的产生和发展,摆脱了以往数学的繁琐和逻辑化,而改用平常的语言,通俗的对话体作为阐述方式,让数系、极限等系统的知识贯穿于全书。并且告诉我们一些无法用语言描述的道理,很值得一看。。。

对话体形式来讨论自然数这个基础,在此基础上定义了加法和乘法,非常的严谨,不过也很抽象比较难以理解,对人的挑战很大!

虽然是大神写的。。。可是读了一半就读不下去了。不是很喜欢这种风格。。。

第一口气读完了1-3章,第二口气读完了剩余部分;不推公式也很好看。
