Einstein's correction to his formula for the viscosity coefficient = 1 a key equation in his 1905 doctoral thesis in which he had presented a new theoretical method for determining molecular radii and Avogadro's number. In 1910 Jacques Bacelin a pupil of French physicist Jean-Baptiste Perrin obtained experimental results indicating a possible error in Einstein's formula. "That prompted Einstein after an unsuccessful attempt to find an error to ask his student and collaborator Ludwig Hopf to check his calculations and arguments . . . Hopf did find an error in the dissertation namely in the derivatives of some velocity components and obtained for a corrected coefficient 2.5 . . .In early 1911 Einstein submitted his correction for publication and recalculated Avogadro's number. He obtained a value of 6.56 x 1023 per mole a value that is close to those derived from kinetic theory and Planck's black-body radiation theory" Duplantier pp. 216-217.

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.

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.

"In 1907 Einstein published a paper entitled 'Theoretical Observations on the Brownian Motion' in which he considered the instantaneous velocity of a Brownian particle. Einstein showed that by measuring this quantity one could prove that 'the kinetic energy of the motion of the center of gravity of a particle is independent of the size and nature of the particle and independent of the nature of its environment.' This is one of the basic tenets of statistical mechanics known as the equipartition theorem. However Einstein concluded that due to the very rapid randomization of the motion the instantaneous velocity of a Brownian particle would be impossible to measure in practice.

1906réf. 432891906. Einstein Albert 1879-1955. Über eine Methode zur Bestimmung des Verhältnisses der transversalen und longitudinalen Masse des Elektrons. Offprint from Annalen der Physik 21 1906. 583-586pp. 223 x 145 mm. Original printed wrappers chipped spine splitting minor spotting. Light toning but very good. First Edition Rare Offprint Issue. 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 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.

1915réf. 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.
