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.

好書要多讀
评分首先, 當然沒有AdS/CFT, 因為成書時間是1998年, 那時maldacena纔剛把文章po齣來呢. 捲2是講superstring，感覺很多地方寫得不盡如人意，比如S-duality(我在期待錶格羅列沒錯), 比如fermionic d.o.f的引入(我在期待Green-Schwartz formalism沒錯), 和Becker的書配閤著看會好一些. 補充評論:日子久瞭又覺得還是Polchinski講得好...可能是情懷作祟吧. chap13的D-brane總結得挺詳細——盡管非微擾objects在技術上和微擾弦很不一樣. 最後要為評論區不滿此書濫用vertex operator這一說法鳴不平:守住2-dim CFT層麵的完備描述是弦論量子化的最後一點尊嚴啊.
评分好書要多讀
评分第十章到第十四章寫的太好瞭，可惜沒有講ADS/CFT
评分感覺Polchinski的弦論和Weinberg的量子場論都被鬼畜的排版和字體毀瞭，真不知道這公式字體是哪來的，以前還好，現在眼睛被慣壞瞭看到後像在吃屎實在沒心情讀下去..
