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.

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.

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.

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.

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.

Later orange cloth gilt-stamped spine title; spine faded. Very good. TWO PAPERS FROM THE TWO GIANTS OF 20TH CENTURY PHYSICS AS THEY WERE ORIGINALLY PUBLISHED IN ONE COLLECTED VOLUME. 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.

6866Einstein Albert. Nobel Prize winning physicist. Vintage Signed Photo. A sepia candid photo of Einstein talking to another man Signed by Einstein on the blank verso in ink "Albert Einstein". Photo is aprox 3.5 in x 5 in and verso is a blank postcard as it was fashionable in the 1930's. Einstein wears a cap and is in profile the other man has his back to us. They are both wearing winter overcoats and are having a conversation outdoor by what seems to be a boat mass. This unique candid shot seems to be taken on one of Einstein many trips aboard vessels in the 1930's. Einstein said on a boat he was oblivious to everything else in the world and once wrote "A cruise in the sea is an excellent opportunity for maximum calm and reflection on ideas from a different perspective." The signature is very clean and dark and in very good condition. unknown books

19361198491936. Rare typed letter signed by Albert Einstein. One page typescript text in German. The letter is dated 19 June 1936 and addressed to Dr. Hugo Bergman Hebrew University Jerusalem and reads: Lieber Herr Bergmann: Ueberbringer dieses Briefes ist "Seine amerikanische Heiligkeit" Rabbi Silberfeld von Newark New Jersey ein guter Bekannter von mir. Zuhause aller Wege kundig nicht aber in Palaestina. Es ware lieb von Ihnen wenn Sie ihm ein paar Winke gaben damit er sich dort zurechtfindet. Herzlich grusst Sie Ihr "A. Einstein." This translates as: Dear Mr. Bergmann: The bearer of this letter is "His American Holiness" Rabbi Silberfeld of Newark New Jersey a good friend of mine. At home he knows all the ways but not in Palestine. It would be nice of you if you gave him a few hints. yours "A. Einstein." Einstein's close personal friend Rabbi Julius Silberfeld was the rabbi of Temple B'nai Abraham in Newark New Jersey from 1902 to 1939. After it became clear that he could not return to Germany with Hitler's rise to power during his 1933 visit to the United States Einstein resided in England and Belgium for several months before returning to the U.S. where he accepted a position at the Institute for Advanced Study in Princeton New Jersey noted for having become a refuge for scientists fleeing Nazi Germany. It was here that he likely met and formed a close bond with Rabbi Silberfeld. The recipient of the letter Hugo Bergmann was the first rector of the Hebrew University of Jerusalem between 1935 and 1938 which Einstein was instrumental in establishing in 1925 and was among its first Board of Governors. The letter is in near fine condition with a small paper clip imprint. Desirable with noted provenance.
