Otto Stern

thumb|Otto Stern (1940s) Otto Stern (17 February 1888 – 17 August 1969) was a German American physicist and 1943 Nobel laureate in physics "for his contribution to the development of the molecular ray method and his discovery of the magnetic moment of the proton." Quotes A simple calculation shows that from the classical theory follows that we should find a broadening of the beam with the maximum intensity on the place of the beam without field. However, from the quantum theory follows that we should find there no intensity at all, and deflected molecules on both sides. The beam should split up in two beams corresponding to the two orientations of the magnet. The experiment decided in favor of the quantum theory. the conclusion of the historical Stern-Gerlach experiment, in The Method of Molecular Rays, Nobel Lecture, December 12, 1946. About Otto Stern In his obituary for Stern Isidor Rabi Rabi wrote: “Some of Pauli’s great theoretical contributions came from Stern’s suggestions, or rather questions; for example, the theory of magnetism of free electrons in metals.” From Charles Enz Charly Enz and Armin Telling – Pauli’s last two assistants – I have learned that Pauli has also discussed the question of Zero-point energy zero point energies extensively with Stern during his Hamburg time, before the advent of the new quantum mechanics.
