1921rif. 1014Paris: Gauthier-Villars 1921. 1st Edition. FIRST FRENCH EDITION OF A 1921 LECTURE BY EINSTEIN ON THE "GEOMETRIZATION OF PHYSICS AND RELATIVITY AND THE RELATION OF MATHEMATICS TO THE EXTERNAL WORLD" Dictionary of Scientific Biography 4 330. WEIL 115b. French translation by Maurice Solovince. In the same year in which he won the Nobel Prize 1921 Einstein delivered this paper as a lecture at "a commemorative session of the Prussian Academy of Sciences in honor of Frederick the Great" Calaprice Einstein Almanac 65. In "Geometrie und Erfahrung" Geometry and Experience Einstein advances his theory that space conforms to non-Euclidean principles of geometry -- a corollary of the Theory of Relativity - and as stated generally sums up his views on the "geometrization of physics and relativity and the relation of mathematics to the external world" DSB. It is in this lecture that Einstein also provides his famous answer to the puzzling question of why mathematics should be so well adapted to describing the external world: "Insofar as the laws of mathematics refer to the external world they are not certain; and insofar as they are certain they do not refer to reality" ibid. Calaprice put it like this: "He questioned whether human reasoning even without direct experience could lead to an understanding of the properties of real things merely through thought" Calaprice 1921.

RARE FIRST EDITION IN ORIGINAL WRAPPERS OF THE REPORTS FROM THE HISTORIC FIRST SOLVAY CONFERENCE "THE FIRST INTERNATIONAL CONFERENCE IN PHYSICS EVER ORGANIZED" AND A CRITICAL MOMENT IN THE BIRTH OF QUANTUM PHYSICS. In the short time that followed Planck's hypothesis of the universal constant that would bear his name the greatest minds in physics were largely at a loss about how to deal with the bizarre theoretical results that followed let alone the experimental results which confirmed them!. Much of the focus at the time was on black-body radiation including work by Planck himself as well as Lorentz Rayleigh and Jeans. However shortly before the first Solvay conference a young Einstein had also started investigating the related question of materials' specific heat. Kuhn. "The purpose of the first Solvay Conference was thus two-fold: first there was the need to examine whether classical theories molecular-kinetic theory and electrodynamics could in some undiscovered ways provide an explanation of the problem of black-body radiation and of the specific heat of polyatomic substances at low temperatures; secondly to consider phenomena in which the theory of quanta could be successfully used." Mehra. Underlying these questions was the more fundamental mystery of how to interpret the existence of the Planck constant. There were two camps both of which were represented at the conference. Planck's took the constant to indicate some fundamental constraint on the radiative processes of emission and absorption. For example "Sommerfeld introduced a version of the quantum hypothesis which he considered to be compatible with classical electrodynamics. He postulated that in 'every purely molecular process' a quantized quantity of action is exchanged." Staumann. Einstein's camp on the other hand took the quantum of action to represent the physicality of a perhaps pseudo-corpuscular theory of energy exchange - his photons of light. Although the debates that followed the lectures included in the proceedings did not rise to the famous heated exchange that Einstein would have with Bohr at the 1927 Solvay conference we do see some of the young Einstein's hotheadedness as he opens the debate following Planck's plenary lecture: "What I find strange about the way Mr. Planck applies Boltzmann's equation is that he introduces a state probability W without giving this quantity a physical definition. If one proceeds in such a way then to begin with Boltzmann's equation does not have a physical meaning." As translated by Straumann. It would take another 14 years for quantum mechanics to be fully formalized but the first Solvay conference represents a pivotal point in quantum history: "During 1911 the situation changed quickly. Articles that applied the quantum to other topics then outnumbered those on blackbody radiation for the first time and some were backed by impressive experimental evidence. In part because of that evidence physicists like Planck and Lorentz who had previously taken the constant h to be characteristic only of the radiation problem began to consider additional areas in which others had earlier staked quantum claims." Kuhn. Albert Einstein and the Solvay Conference: Among the most renown scientists of the day - including Ernest Rutherford Marie Curie and Max Planck - Einstein made quite an impression. At age 32 he was the second youngest participant in the conference. The youngest was British physicist Frederick Lindemann later to become scientific adviser to Winston Churchill. Although "Einstein had already published so many masterpieces none had actually been put to the test and his theories were looked on rather as tours de force than as definitive additions to knowledge. But his pre-eminence among the twelve greatest theoretical physicists of the day was clear to any unprejudiced observer." Frederick Lindemann quoted in Brian.

1921rif. 009633Paris: Gauthier-Villars 1921 12mo 19 cm XXII 120 pp. Printed wrappers wrappers slightly stained and frayed; small portions of paper missing from the spine; paper toned inside. Early French edition of Einstein's celebrated popular exposition of the theory of relativity intended to make the fundamental ideas of both the special and the general theory accessible to non-specialists. With a preface by the renowned mathematician Émile Borel who emphasizes the scientific importance of Einstein's work and its profound implications for modern physics. Einstein's text explains the essential concepts of space time motion gravitation and the structure of space-time in clear largely non-technical language presenting the empirical and conceptual foundations of relativity to a broad readership. The French translation was prepared by Maurice Solovine one of Einstein's close early collaborators and an important mediator of his ideas to the French-speaking public. Boni-Russ-Laurence 91.B.

rif. 1061Braunschweig: Druck und Vieweg. 1st Edition. FIRST EDITION FULL VOLUME OF THE PAPER IN WHICH EINSTEIN PROVIDES THE FIRST DESCRIPTION OF THE NATURE OF THE REFRACTIVE INDEX FOR X-RAYS here clearly demonstrating that phase contrast effects are significant. "Inspired by the presence of fringes at the edges of objects in early X-ray images and by considerations of optical dispersion theory Einstein suggested in 1918 that the real part of the index of refraction for X-rays in matter is slightly less than unity. This was confirmed in 1924 by Larsson et al. in measurements of wavelength-dependent refraction of X-rays by a prism" Hornberger Quantitative Amplitude 1. "A century later most x-ray microscopy and nearly all medical imaging remains based on absorption contrast even though phase contrast offers orders of magnitude improvements in contrast and reduced radiation exposure at multi-keV x-ray energies"ResearchGate November 2015. Weil 104. Note that we offer this paper separately in its original printed wraps. ALSO INCLUDED: Einstein's reply to Gehrcke's paper "Über den Äther" also present in this volume pp. 165-169.

1954rif. 195551954. in German black ink. Signed “A. Einstein”. A poem written by Einstein to his colleague and collaborator Ernst Straus and his son Daniel. “Dear Strausse both! My best wishes and greetings in poetic form. It brings even more happiness If it has been anticipated for so long also in one’s circle of friends the event is doubly appreciated. This is what I wish: Let Daniel be like his father thoroughly intelligent and not less joyous so few humans are like that. Many - alas - are born few are chosen to bring light and joy. Let such gift be his drive. Yours A. Einstein” In German “Strauss” means bunch bouquet etc. or ostrich and “Strausse” is plural. Ernst G. Straus 1922-1983 was a mathematician who helped found the theories of Euclidean Ramsey theory and of the arithmetic properties of analytic functions. He was Einstein’s assistant and collaborator both at Princeton and afterwards when he moved to become a professor of mathematics at UCLA. His son Daniel is a professor of chemistry at Cal State San Jose. unknown
