String Theory (Cambridge Monographs on Mathematical Physics) (Volume 1)
"...the most comprehensive text addressing the discoveries of the superstring revolutions of the early to mid 1990's, which mark the beginnings of 'modern' string theory."Donald Marolf, University of California Santa Barbara, American Journal of Physics"Physicists believe that the best hope for a fundamental theory of nature--including unification of quantum mechanics with general relativity and elementary particle theory--lies in string theory.  This elegant mathematical physics subject is expounded by Joseph Polchinski in two volumes from Cambridge University Press...Written for advanced students and researchers, this set provides thorough and up-to-date knowledge."American Scientist"...this is an impressive book.  It is notable for its consistent line of development and the clarity and insight with which topics are treated...It is hard to think of a better text in an advanced graduate area, and it is rare to have one written by a master of the subject.  It is worth pointing out that the book also contains a collection of useful problems, a glossary, and an unusually complete index."Physics Today"We would like to stress the pedagogical value of the present book.  The approach taken is modern and pleasantly systematic, and it covers a broad class of results in a unified language.  A set of exercises at the end of each chapter complements the discussions in the main text.  On the other hand, the introduction of techniques and concepts essential in the context of superstrings makes it a useful reference for researchers in the field."Mathematical Reviews"Polchinski's books are a classic textbook on string theory. And I recommend it to you if you want to start the study of string theory... the first volume is an excellent textbook and a great introduction to string theory. Presents some deep chapters, but overall a great book for any student interested in entering the world of string theory. The book is consistent with the objective set out, well written for graduate students and probably one of the best textbooks on the market about string theory and shall remain so for a long time. these two books are great and of excellent quality. The book is consistent with the goal set in the early chapters, presents clear language with few errors and with a high degree of mathematical rigor. The book contains an excellent range of problems and an excellent glossary and the educational value of this book is incalculable. Definitely these books are references for the study in string theory and it will stay with this position."Philosophy, Religion and Science Book Reviews Blog
