We adopt, as most mathematicians do, the naive point of view regarding set theory.
We shall assume that what is meant by a set of objects is intuitively clear, and we shall
proceed on that basis without analyzing the concept further. Such ananalysis properly
belongs to the foundations of mathematics and to mathematical logic, and it is not our
purpose to initiate the study of those fields.

最新版的《Perl程序设计<第四版>》！Perl创始人唯一相关书籍！学习Perl编程语言必备！
Programming Perl: Unmatched power for text processing and scripting By Tom Christiansen, brian d foy, Larry Wall, Jon Orwant Ph.D.
Fourth edition 2012 | 1176 Pages | ISBN: 0596004923 | PDF | 20 MB
Adopted as the undisputed Perl bible soon after the first edition appeared in 1991, Programming Perl is still the go-to guide for this highly practical language. Perl began life as a super-fueled text processing utility, but quickly evolved into a general purpose programming language that’s helped hundreds of thousands of programmers, system administrators, and enthusiasts, like you, get your job done.
In this much-anticipated update to "the Camel," three renowned Perl authors cover the language up to its current version, Perl 5.14, with a preview of features in the upcoming 5.16. In a world where Unicode is increasingly essential for text processing, Perl offers the best and least painful support of any major language, smoothly integrating Unicode everywhere—including in Perl’s most popular feature: regular expressions.
Important features covered by this update include:
New keywords and syntax
I/O layers and encodings
New backslash escapes
Unicode 6.0
Unicode grapheme clusters and properties
Named captures in regexes
Recursive and grammatical patterns
Expanded coverage of CPAN
Current best practices

ap课程， 必看。微积分 极限。
微积分：Calculus课程容易学，容易考，且容易换学分。所谓的容易学，是指微积分课程结构简单，知识框架清晰，方便学生自学，也方便学生考前冲刺。容易考，是因为微积分卷面分数108分，大概获得80分就能拿到5分，最高等级。容易换学分，是因为大多数的专业大一都是需要学微积分的，用AP Calculus肯定能换取学分。不会像某些比较偏的课程一样，不是必修，考过考不过都不能换学分。
