Title: An excellent treatment of quantum theory of fields
Review: Weinberg shows not only his mastery of the subject but also his skills as a teacher. The book is easy to understand provided one has mastered relativity and quantum mechanics. It would be an excellent complement for anyone who has read Bjorken/Drell or Peskin/Schroeder. In my opinion, a true understanding of quantum field theory can only be gained if one reads Bjorken/Drell, then Peskin/Schroeder and then finally Weinberg. In his book Weinberg is sort of recombining the best of Bjorken/Drell and Peskin/Schroeder and brings understanding to a new level. It is in a sense like with having read quantum mechanics by say Messiah and then reading Landau. Reading Landau first is not a good idea, but doing it after Messiah is. The same thing applies for Weinberg but for a different reason. His insight is more sparking that way.
