Volume 2: Superstring Theory and Beyond, begins with an introduction to supersymmetric string theories and goes on to a broad presentation of the important advances of recent years. The book first introduces the type I, type II, and heterotic superstring theories and their interactions. It then goes on to present important recent discoveries about strongly coupled strings, beginning with a detailed treatment of D-branes and their dynamics, and covering string duality, M-theory, and black hole entropy, and discusses many classic results in conformal field theory. The final four chapters are concerned with four-dimensional string theories, and have two goals: to show how some of the simplest string models connect with previous ideas for unifying the Standard Model; and to collect many important and beautiful general results on world-sheet and spacetime symmetries.

感觉Polchinski的弦论和Weinberg的量子场论都被鬼畜的排版和字体毁了，真不知道这公式字体是哪来的，以前还好，现在眼睛被惯坏了看到后像在吃屎实在没心情读下去..
评分好书要多读

评分首先, 当然没有AdS/CFT, 因为成书时间是1998年, 那时maldacena才刚把文章po出来呢. 卷2是讲superstring，感觉很多地方写得不尽如人意，比如S-duality(我在期待表格罗列没错), 比如fermionic d.o.f的引入(我在期待Green-Schwartz formalism没错), 和Becker的书配合着看会好一些. 补充评论:日子久了又觉得还是Polchinski讲得好...可能是情怀作祟吧. chap13的D-brane总结得挺详细——尽管非微扰objects在技术上和微扰弦很不一样. 最后要为评论区不满此书滥用vertex operator这一说法鸣不平:守住2-dim CFT层面的完备描述是弦论量子化的最后一点尊严啊.
评分got a general flavour. Good on superstring&duality discussion, but used the language of vertex operator unnecessarily too much, doesn't discuss ADS/CFT, prefer BBS
