读起来不轻松。。。不过能和一个人擦出思想的火花一定是很美妙的一件事:) "There are infinitely many things yet to do...and only a finite amount of time..."

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.
非常不错的一本书,如果你想学习怎么让爱情保鲜,如果你想学习如何在平淡的生活中保持激情,或者你只是对学术感兴趣,对创新思维感兴趣,对数学感兴趣,或者你只是想更多地了解高德纳,这本书都值得一看 力荐 ----- 大多数人可能更多从学术方面来看。其实我觉得这本书带给读...
评分由于书中的集合论方面的东西在大学里面学过,所以我更注重本书中所描述的对知识的发现过程,或者说对问题的发现过程 工作中,难得不是去怎样解决问题,而是去定义问题,甚至是发现问题! 书中部分用词是很哲学化的,从某种程度上,这本书给我们的只是心法,只有切身体会那种...

评分确实是好东西,很值得一看,个人认为出彩的部分是译者对作者意思的精准把握,确实是传神之作。 第 25 页“如果成立的话,那我就会将 (Y, phi) (此处 phi 表示空集)称为“正”数”,之后又发现此中 Y 必须满足其中至少一个元素大于或相似于 0,只要满足了这个条件,它就成被称...
评分当我们想当然地总是assume too much还自以为经验丰富、懂得多的时候,真正的数学家们总会本能地问上一句为什么会有这样的现象,这样的现象是否就是“事实”,是否能找到证明...然后就有了公理、然后就有了简约优美或繁琐复杂的重重证明、然后就有了引理、然后就有了定理... Kn...
