Abstract
J M Ziman London: Cambridge University Press 1969 pp xii + 269 price £2.75 The days are long since past when a knowledge of the Schrödinger equation, or perhaps even of the Dirac formalism and the algebra of Hilbert space, was sufficient equipment to enable theoretical papers on aspects of quantum theory to be read and understood. Today one is faced with the symbols and concepts (field operators, Feynman graphs, Green functions, the S matrix, and so on) of what to many must seem an inaccessible world.
