8vo. Pages 348-365. [Entire volume: vii, 846 pp.] 17 figs. Navy cloth, gilt spine. Blind-stamp of the Carnegie Institution of Washington, Mount Wilson Observatory. Fine. FIRST EDITION. "The period 1923-1933 marks the peak of Stern's contributions to physics. Shortly after assuming his post at Hamburg on 1 January 1923, he set out to organize a laboratory specially equipped for molecular-beam research and to devise a program for conducting this research, which was executed, to a large degree, with remarkable success. . . . [The program was concerned] with demonstrating the wave nature of particles - a revolutionary assumption introduced in 1924 by Louis de Broglie that became the foundation of modern quantum mechanics. . . . The significance of the work on the wave nature of particles is similar to that of the Stern-Gerlach experiment: each provided unambiguous, direct, and thoroughly convincing proof of revolutionary concepts introduced into the foundations of physics. These experiments were essential for the acceptance of new ideas that had previously been regarded with considerable skepticism." DSB. DSB, XIII, pp. 40-43.…

Hardcover. Condición: Very Good. FRISCH, Otto Robert (1904-1979) & Otto STERN (1888-1969). "Uber die magnetische Ablenkung von Wasserstoffmolekulen und das magetische Moment des Protons. I." With: ESTERMANN, I. & Otto STERN. "Uber die magnetische Ablenkung von Wasserstoffmolekulen und das magetische Moment des Protons. II." In: "Zeitschrift fur Physik," vol. 85, with the papers on pp 4-16; 17-24 pp in the full volume of viii, 811 pp. [++] Bound in black cloth. [++] "The last part of Stern's program had a completely different outcome. Dirac had promulgated a theory according to which the ration of the magnetic moment of the proton to that of the electron should have been the same as the inverse ration of their masses. This theory was believed so generally that when Stern, O. R. Frisch, and this writer began the very difficult experiments, they were told more than once by eminent theoreticians that they were wasting their time and effort. But Stern's perseverance paid off. Measurements showed a proton magnetic moment two or three times larger than expected. While that result has since been reproduced with greater accuracy, a really satisfactory theoretical explanation is still outstanding. It is this work that was specifically mentioned in Stern's Nobel Prize citation." - Complete DSB online.
