First ediiton offprint issue. "Since after 1917 Einstein firmly believed that light-quanta were here to stay it is not surprising that he would look for new ways in which the existence of photons might lead to observable devations from the classical picture. In this he did not succeed. At one point in 1921 he thought he had found a new quantum criterion published in the present paper but it soon turned out to be a false lead" Pais Subtle is the Lord pp. 412-413.

In his landmark 1905 paper on special relativity Einstein used the velocity-dependent concepts of transverse and longitudinal mass for the moving electron these terms have now been replaced with the concept of relativistic mass first defined by Lewis and Tolman in 1909. In the present paper Einstein proposed an experimental method for determining the ratio of the transverse to the longitudinal mass and invited experimentalists to verify his special theory of relativity. Einstein later abandoned velocity-dependent mass concepts stating in 1948 that "it is better to introduce no other mass concept than the ‘rest mass' m" quoted in L. B.

Einstein's "Generalized Theory of Gravitation" is considered the last principal work issued by the 20th Century's premiere scientist. Schilpp-Shields. <br /><br /> Einstein: "A new presentation. . . which constitutes a certain progress in clarity as compared with previous presentations." from the Introduction. Feynman: "At first Feynman's fundamental article RMP 1948 did not arouse much interest among theoretical physicists who were not familiar with Feynman's new approach to doing quantum mechanics. As Feynman recalled: 'At the Shelter Island Conference. . . they asked me if I would explain my path-integral method for doing quantum mechanics so I did. I must have been preparing the manuscript for my paper RMP 1948 so that everything was organized and I explained it. It's hard to pay attention to some new idea and they didn't pay much attention to it.' However nowadays Feynman's RMP 1948 paper is one of the most well-known and widely cited papers; it is one of the cornerstones of modern theoretical physics." Mehra. <br /><br /> "It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. . . This paper will describe what is essentially a third formulation of non-relativistic quantum theory. This formulation was suggested by some of Paul Dirac's remarks concerning the relation of classical action to quantum mechanics. A probability amplitude is associated with an entire motion of a particle as a function of time rather than simply with a position of the particle at a particular time." from the Introduction.

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.

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.

1922432871922. <p>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. </p> <p>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. </p> <p>Einstein and Ehrenfest addressed one of these difficulties—connected with space quantization—in their joint paper in which </p> <p>"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. </p> <p>Pais Subtle is the Lord p. 328.

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.

1915432951915. <p>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.</p> <p>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.
