First Edition. viii, 142 pp; 29 figs., 3 plates. Original linen (a little soiled). Very Good+. Contributors include: Dirac ("Zur Quantentheorie des Elektrons"); Fermi ("Ueber die Anwendung der statistischen Methode auf die Probleme des Atombaues"); Hinshelwood; Kossel; London; Eucken; and Sidgwick. Dirac’s paper "The Quantum Theory of the Electron" "probably Dirac's greatest contribution to physics, was received by Proceedings of the Royal Society on January 2, 1928. The first occasion at which Dirac himself presented his theory to the German physicists was when he delivered a lecture to the Leipziger Universitätswoche during June 18-23, 1928. This was the first in a series of annual symposia on current research in physics, and it was arranged by Debye and Heisenberg, the new professors of physics at Leipzig. Dirac gave a survey of his new theory and called attention to a further argument for the linear wave equation. Dirac’s theory of the electron had a revolutionary effect on quantum physics. It was as though the relativistic equation had a life of its own, full of surprises and subleties undreamed of by Dirac when he worked it out" (Kragh, Dirac, pp. 57 and 64). Fermi’s paper concerned "the application of his statistics to an atomic model. The Thomas-Fermi atom gives very good approximations in a great number of problems. Many of these results were summarized in a paper he read at the University of Leipzig in 1928" (D. S. B. 4: 578). …
