Heisenberg’s early work and its relation to wave mechanics and to experiment is described in Die physikalischen Prinzipien der Quantentheorie (Leipzig, 1930), translated by Eckart, Carl and Hoyt, Frank C. as The Physical Principles of the Quantum Theory (Chicago, 1930). The theory of the S-matrix is explained in “Die ‚beobachtbaren Größen’ in die Theorie der Elementarteilchen”, in Zeitschrift für Physik, Vol. 120 (1943), 513–538 and 673–702. For a survey of Heisenberg’s new field theory, see “Quantum Theory of Fields and Elementary Particles”, in Reviews of Modern Physics, Vol. 29 (1957), 269–278, and “Die Entwicklung der einheitlichen Feldtheorie der Elementarteilchen”, in Naturwissenschaften, Vol. 50 (1963), 3–7. Die Physik der Atomkerne (Braunschweig, 1943) explains nuclear physics and Heisenberg’s contributions to it. Wandlungen in den Grundlagen der Naturwissenschaften (Leipzig, 1935) is a survey of advances and discoveries from 1900 to 1930. Physics and Philosophy (New York, 1959), which contains the Gifford lectures given in 1955/1956, deals with the same subject on a broader historical and philosophical basis and also discusses current objections to the Copenhagen interpretation of quantum theory.Google Scholar
