1933réf. 180318Amsterdam: Koninklijke Akademie van Wetenschappen 1933. First edition offprint issue of the third of Einstein and Mayer's four classic papers on semi-vectors in which they aimed to incorporate the Dirac equation into the general theory of relativity. "By introducing semi-vectors Einstein wanted to arrive at a mathematically simpler and more general formulation of spinors. The semi-vector generalization of the Dirac equation was thought to give a unified description of charged elementary particles in particular of the electron and proton" Van Dongen pp. 103-5.

1914réf. 1199Braunschweig: Friedr. Vieweg & Sohn 1914. 1st Edition. FIRST EDITION FULL VOLUME OF THE FRANCK-HERTZ EXPERIMENT: THE FIRST ELECTRICAL MEASUREMENT TO CLEARLY SHOW THE QUANTUM NATURE OF ATOMS - PROOF OF THE QUANTIZED MODEL OF THE BOHR ATOM & OF PLANCK'S QUANTUM THEORY. Note that this volume includes both the first and second Franck-Hertz experiment. In the first they demonstrate that atoms can only absorb and be excited by specific amounts of energy; in the second experiment performed the same year they demonstrate that the frequency of the light emitted following the collision of electrons with mercury atoms corresponds precisely with the energy lost by the electrons in the collision. Franck and Hertz received the Nobel Prize for this work specifically "for their discovery of the laws governing the impact of an electron upon an atom" Nobel Prize Committee. Of equal import this volume also contains a paper by Einstein in which he uses the light quantum hypothesis to give new derivations of Planck's radiation law and Nernst's third law of thermodynamics. His "proofs introduced the quantum hypothesis" Calaprice The Einstein Almanac 40. In 1914 James Franck and Gustav Hertz were working together in the Physics Institute of Berlin and were "particularly interested in ionization i.e. in the process in which an electron is removed from an atom" The Harvest of a Century" p. 102-103. The experiment they devised now known commonly as the Franck-Hertz experiment is "a vivid illustration of the quantization of energy" that relied on methodology so simple "that it is now carried out regularly by undergraduates. They accelerated electrons through a low-pressure gas of mercury. When the electrons' energy reach the energy of a stationary state of mercury they gave up a quantum of energy to the mercury resulting in a stepwise shape to the curve of current through the apparatus. This demonstrated that atoms could absorb energy only in discrete amounts" Peacock The Quantum Revolution 40. "Franck and Hertz had not only shown for the first time that electrons lose their kinetic energy to mercury atoms in energy quanta but also that these energy quanta are equal to the energy of the light emitted by the same atoms if interpreted with Einstein's light-quantum hypothesis.This was the first experimental determination of Planck's constant not using blackbody radiation" Brandt 103.

In "Relation between elastic behaviour and specific heat of solid bodies with monatomic molecules" Einstein comments Sutherlands importent paper in Philosophical Magazine from 1910. Sutherland made the importent remark that the infrared eigenfrequencies of solid bodies have their origin possibly in the elastic vibrations of these bodies. Einstein impressed by this remark adds that electrically charged ions are the sources of optical vibrations whreas elastic vibrations are caused by the mutual motion of the entire molecule. Hence he prefers to test the hypothesis of Sutherland by solid bodies which are composed of monatomic molecules."Lanczos. - Weil Nos 38 39 this with an asterix denoting major work40 1-2 and 41. unknown

1915réf. 1200Braunschweig: Friedr. Vieweg & Sohn 1915. 1st Edition. FIRST EDITION FULL BOUND VOLUME OF THE EINSTEIN-DE HAAS EFFECT -- an experimental observation that illustrates the relationship between magnetism and angular momentum and in which a change in the magnetic moment causes the rotation of a free body. In this 1915 paper Albert Einstein and Wander de Haas report that changing the magnetization of a suspended iron rod by applying an external magnetic field leads to mechanical rotation of the rod - a result that still stands as a textbook illustration of the relationship between magnetism and angular momentum. Papers by Planck The Quantum Hypothesis for Molecules with Multiple Degrees of Freedom von Laue Warburg Siegbahn and Born are also present. Einstein had long contemplated Ampère's 1820 conjecture that magnetism is caused by the microscopic circular motions of electric charges. In light of this Einstein and de Haas devised an experiment to test not just Ampère's hypothesis but also "Lorentz's theory that the rotating particles are electrons. The aim of the experiment was to measure the torque generated by a reversal of the magnetization of an iron cylinder" Calaprice Einstein Almanac 52. In the experiment Einstein and de Haas designed "a magnetic material was suspended with the aid of a thin string inside a magnetic field coil. When the magnetic field was increased by the application of an electric current through the field coil the magnetic material is magnetized. In order to keep the total magnetic moment of the magnetic material constant the latter rotates. This classical Einstein-de Haas effect demonstrates that the spin angular momentum is of the same nature as the angular momentum of rotating bodies as conceived in classical mechanics" Ganzhorn Nature Communications 7 11443 2016. Einstein spoke enthusiastically of the experimental results he and de Haas has achieved stating that they had "given firm proof of the existence of Ampère's molecular currents" Pais Subtle is the Lord 245. ALSO INCLUDED: Papers by Planck "Die Quantenhypotese für Molekeln mit mehreren Freiheitsgraden" and "Bemerkung über die Entropiekonstante zweiatomiger Gase" as well as a paper by von Laue "Die Einsteinischen Energieschwankungen" CONDITION & DETAILS: Braunschweig: Friedr.
