几年前，“数学之美”系列文章原刊载于谷歌黑板报，获得上百万次点击，得到读者高度评价。读者说，读了“数学之美”，才发现大学时学的数学知识，比如马尔可夫链、矩阵计算，甚至余弦函数原来都如此亲切，并且栩栩如生，才发现自然语言和信息处理这么有趣。
今年，作者吴军博士几乎把所有文章都重写了一遍，为的是把高深的数学原理讲得更加通俗易懂，让非专业读者也能领略数学的魅力。读者通过具体的例子学到的是思考问题的方式 —— 如何化繁为简，如何用数学去解决工程问题，如何跳出固有思维不断去思考创新。

This is the story of Linus Torvalds, the maverick Finnish computer genius who invented the powerful LINUX operating system. As well as being free, LINUX is more powerful and stable than anything that Microsoft can offer, thus making Torvalds Bill Gates' number one enemy. Today, LINUX is exploding on to the market, and its creator is household. Linus Torvalds is already a folk hero within the technolgy world, often mobbed at trade shows and forever asked to give interviews by the media. But Torvalds is a most unlikely celebrity: a family man, he lives in a cramped house in Santa Clara with his wife, Tove, a Finnish karate champion, and their two daughters. He claims to this day that he invented LINUX "just for fun". --This text refers to an out of print or unavailable edition of this title.
