1915ref. 432951915. Einstein Albert 1879-1955 and Wander Johann de Haas 1878-1960. Notiz zu unserer Arbeit "Experimenteller Nachweis der Ampèreschen Molekularströme." Offprint from Verhandlungen der Deutschen Physikalischen Gesellschaft 17 1915. 1 sheet p. 420. 228 x 156 mm. Original printed wrappers. Fine copy. First Edition Offprint Issue. In 1915 Einstein and Dutch physicist Wander Johannes de Haas conducted gyromagnetic experiments leading to the discovery of the Einstein-de Haas effect which corresponds to the mechanical rotation induced in a ferromagnetic cylinder suspended inside a coil when an impulse of electric current is sent through the coil. Einstein was very enthusiastic about the experimental results stating that he and de Haas had "given firm proof of the existence of Ampère's molecular currents" quoted in Pais Subtle is the Lord pp. 245-246. Einstein and de Haas published their results in a paper published earlier in 1915 see Weil 73; the present "Notiz" is a response to a communication from American physicist Samuel Jackson Barnett who had begun performing similar experiments in 1909 and obtained results complementing those of Einstein and de Haas.

Original printed wrappers a little chipped and darkened small splits in spine. Very good. First edition offprint issue. Einstein's work on semivectors "was stimulated by Ehrenfest's insistence on a better understanding of the relation between single-valued and double-valued representations of the Lorentz group . . . Einstein and Mayer went on to relate semivectors to the Dirac equation and to generalize the formalism to general relativity" Pais Subtle is the Lord pp. 451-452.

1922ref. 432871922. Einstein Albert 1879-1955 and Paul Ehrenfest 1880-1933. Quantentheoretische Bemerkungen zum Experiment von Stern und Gerlach. Offprint from Zeitschrift für Physik 11 1922. 31-34pp. 229 x 155 mm. Original printed self-wrappers. Light toning but fine otherwise. First Edition Offprint Issue. In 1922 the physicists Otto Stern and Walther Gerlach conducted a now-classic experiment in which a beam of silver atoms was streamed through an inharmonious magnetic field in order to observe the atoms' deflection patterns. Rather than a random and continuous distribution as predicted by classical theory the atoms passing through the field were deflected up or down by a specific amount demonstrating that they had intrinsically quantum properties. The Stern-Gerlach experiment corroborated the Bohr-Sommerfeld model of the atom and strongly influenced later developments in 20th century physics. However the experiment also created some serious difficulties for quantum physicists in the period before the rise of the "new" quantum mechanics. Einstein and Ehrenfest addressed one of these difficulties-connected with space quantization-in their joint paper in which "they dealt in particular with the problem of how the orbits of the atom would obtain their discrete directions which they exhibit while passing through the inhomogeneous magnetic field. Under the assumption that the mechanism causing the orientation was provided by the interaction with the radiation field Einstein and Ehrenfest estimated that for a field strength of 10000 G a change in the direction of the orbit would take place in roughly 1011 s; this long time interval would be reduced in the presence of heat radiation at room temperature . . . to about 109 s. How could they asked the experimental situation be explained which implied that the discrete orientations of the orbits in silver atoms were obtained in less than 10-4 s. In order to deal with this evident puzzle Einstein and Ehrenfest proposed two alternatives: first that the silver atoms were always in the states of spatial quantization; second the orientations of the electron orbits arose from an interaction of the atoms with the radiation field which involved much smaller reaction times . . . However they found that both alternatives created considerable difficulties in the understanding of the atomic processes . . . Thus Einstein and Ehrenfest concluded: 'The difficulties mentioned above show how unsatisfactory are both interpretations of the results found by Stern and Gerlach'" Mehra & Rechenberg The Historical Development of Quantum Theory 1 pp. 443-444.

1923ref. 432881923. Einstein Albert 1879-1955 and Paul Ehrenfest 1880-1933. Zur Quantentheorie des Strahlungsgleichgewichts. Offprint from Zeitschrift für Physik 19 1923. 301-306pp. Original printed self-wrappers. 230 x 157 mm. Light toning but very good. First Edition Offprint Issue. In 1916 after publishing his great work on general relativity Einstein returned to the question of blackbody radiation. In November 1916 he wrote to his friend Besso that "a splendid light has dawned on me about the absorption and emission of radiation" quoted in Pais p. 405 one that led him to a new derivation of Planck's radiation law and convinced him of the reality of light-quanta photons. After publishing these results in three papers culminating with the famous "Zur Quantentheorie der Strahlung" 1917 Einstein kept looking for "new ways in which the existence of photons might lead to observable derivations from the classical picture" Pais p. 413. He found none until 1923 when Arthur Compton and Peter Debye independently derived the relativistic kinematics for the scattering of a photon off an electron at rest. The work of Compton and Debye led Wolfgang Pauli to extend Einstein's work of 1917 to the case of radiation in equilibrium with free electrons see Pais p. 414n. "Pauli examined the requirements of detailed balance under Lorentz transformations and found that scattering of light by free electrons must include a term of a form which we would now call stimulated emission . . . Einstein and Ehrenfest then showed that Pauli's results could be obtained by an extension of Einstein's 1917 paper with the unnecessary specialization to discrete energy levels removed . . . The core of Einstein's argument is that the scattering process should be broken into two parts: the absorption of energy from radiation of frequency 1 and the emission of energy as radiation of frequency 2" Lewis p. 42.

"Some arguments for the assumption of molecular agitation at absolute zero." In this paper Einstein and Stern show that the quantum theory of solids to give the best agreement with experiments at normal temperatures seems to demand that at absolute zero a residual energy would remain in the solids which they term "zero-point energy." They thus introduced this important concept to physics." p. 292. Calaprice Kennefick & Shulmann. An Einstein Encyclopedia. 2015. Otto Stern was a German-American physicist and Nobel Laureate in Physics. He was the second most nominated person for a Nobel Prize with 82 nominations in the years 1925-1945 ultimately winning in 1943 "for his contribution to the development of the molecular rat method and his discovery of the magnetic moment of the proton". In 1912 Stern did his doctoral dissertation in concentrated solutions. After receiving his Ph.D. degree Stern took advantage of his economic independence to join Albert Einstein at Prague.

Einstein's first paper written jointly with a collaborator on the relativistic electrodynamics of ponderable media. "In 1908 Laub wrote works together with Einstein on the basic electromagnetic equations which was aimed to replace the four-dimensional formulation of the electrodynamics by Minkowski by a simpler classical formulation. Both Laub and Einstein discounted the spacetime formalism as too complicated. However it turned out that Minkowski's spacetime formalism was fundamental for the further development of special relativity" Wikipedia. Pais Subtle is the Lord pp. 151 154. Shields 23.

ref. 504141 First Edition journal issue. The brilliant follow-up to Einstein's landmark 1905 paper on the photoelectric effect. In the 1905 paper Einstein had explained the photoelectric effect-the emission of electrons from a metal when irradiated by light-by making the revolutionary proposal that light rather than consisting of continuous waves was instead made up of discrete particles of energy "light quanta" which transferred their entire payload of energy to an electron on impact. In the 1905 paper Einstein made use of Planck's mathematical formula for blackbody radiation which had introduced the concept of energy quanta but he was only able to derive part of the formula. In his 1906 paper Einstein "used his statistical mechanics to demonstrate that when light interacts with matter Planck's entire formula can arise only from the existence of light quanta-not from waves" Cassidy; emphasis ours. Einstein had realized as he stated in the present paper that "'Planck's theory makes implicit use of the . . . light-quantum hypothesis' . . . his acceptance of Planck's formula albeit as a hypothesis led to a major advance in his own work" Pais Subtle is the Lord p. 378.

In the present paper Einstein presented another argument in support of the proposition that a body's energy depends on its energy content. "About a year after he first introduced the inertia of energy Einstein published a paper entitled "The Principle of the Conservation of the Center of Gravity and the Inertia of Energy" in which he showed that E = mc2 is necessary and sufficient to ensure that the center-of-mass theorem holds for systems in which 'not only mechanical but also electromagnetic processes take place' . . . As Einstein acknowledges his paper is similar to Poincaré's contribution to the Lorentz Festschrift 1900. Einstein showed that in order to avoid the kind of violations of the center-of-mass theorem discussed by Poincaré one has to assume that energy has inertia" Janssen pp. 39-40.

1931ref. 1403337Potsdam Germany 1931. Two letters by Albert Einstein. The first is a single-paged autograph letter signed by Albert Einstein with one horizontal fold and one vertical fold. In Very Good condition . Measuring 22.5 x 28.5 cm. Letter accompanied with mailing envelope both with matching paper-clip rust stain. Letter with some light wear along edges small staining to lower corner. Addressed to G. W. Meyer and dated 8 Oktober 31 in Potsdam the Letter reads in full: "Sehr geehrter Herr! Indem ich Ihnen für die Uebersendung des Buches von Henry George bestens danke sende ich Ihnen anliegend die gewünschte Meinungsäusserung mit der Bitte um Weiterleitung an Mrs. Evans. Mit ausgezeichneter Hochachtung" and signed in ink "A. Einstein". He thanks Meyer for serving as an intermediary in getting a book to him and for forwarding the enclosed letter. The second letter is a typed copy of Einstein's previously enclosed letter presumably made by Meyer before he passed the original on to Evans. Addressed to R. W. Evans and dated 8.10.1931 in Potsdam the letter discusses Henry George's economic theory of poverty and land nationalization compares it to Franz Oppenheimer's work and proposes questions to be asked. Presumably he was sent a copy of Henry George's Progress and Poverty. First published in 1879 it sparked the Progressive Era discussing the paradox of increasing inequality and poverty amid economic and technological progress as well as the economic value of land. Consignment. Shelved Case 3. The Letter reads in full: "Sehr geehrte Mrs. Evans!
