Christie's The History of Quantum Physics and the Theory of Relativity: The Harvey Plotnick Library, 101. A scientific history for a casual reader, intended to explain the history of the evolution of famous theories in physics. Einstein and Infeld begin with the "Mechanical View" of the physical universe, the work done by Galileo and Newton, and the subsequent challenges to their work by modern physicists. The authors devote a section to the decline of the mechanical view, and proceed to explain their work on Relativity and Quanta. Einstein was famous for writing books intended to educate the public on his work and on the history of science. This volume is an example of his noble goal in making physics accessible to all readers. A Very Good+ book with a name and date of 1938 on the free front endpaper and toning to the endpapers and pastedowns; dust jacket is Good or better with notable edge wear, resulting in minor loss to the spine panel and folds.

Edition : First Canadian Edition., after the first London., Contemporary full red cloth, title on flat spine, debossed stamped title on the upper board, lacks the dust jacket. , Albert Einstein (1879 ? 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass?energy equivalence formula which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory., Size : Octavo (8vo.), Illustrated with five diagrams and numerous in text mathematical equations. A foundation work in physics and astronomy. A near fine example, text and illustrations clean and crisp.

First edition of this classic account of Born's analysis and interpretation of Einstein's theory of relativity. Octavo, original cloth, frontispiece of Einstein. Signed by Max Born on the verso of the frontispiece. Translated by Henry L. Brose. Very good in a very good dust jacket. Housed in a custom half morocco clamshell box. First editions are uncommon, signed examples rare. Einstein's Theory of Relativity is a book in which one great mind explains the work of another great mind in terms comprehensible to the layman is a significant achievement. This is such a book. Max Born was awarded the Nobel Prize in 1954 and was one of the world's great physicists: in this work he analyzes and interprets the theory of Einsteinian relativity. The result is undoubtedly the most lucid and insightful of all the books that have been written to explain the revolutionary theory that marked the end of the classical and the beginning of the modern era of physics. Born follows a quasi-historical method of presentation. The book begins with a review of the classical physics, covering such topics as origins of space and time measurements, geometric axioms, Ptolemaic and Copernican astronomy, concepts of equilibrium and force, laws of motion, inertia, mass, momentum and energy, Newtonian world system (absolute space and absolute time, gravitation, celestial mechanics, centrifugal forces and absolute space), laws of optics (the corpuscular and undulatory theories, speed of light, wave theory, Doppler effect, convection of light by matter), electrodynamics (including magnetic induction, electromagnetic theory of light, electromagnetic ether, electromagnetic laws of moving bodies, electromagnetic mass, and the contraction hypothesis). Born then takes up his exposition of Einstein's special and general theories of relativity, discussing the concept of simultaneity, kinematics, Einstein's mechanics and dynamics, relativity of arbitrary motions, the principle of equivalence, the geometry of curved surfaces, and the space-time continuum, among other topics. Born then points out some predictions of the theory of relativity and its implications for cosmology, and indicates what is being sought in the unified field theory. This work steers a middle course between vague popularizations and complex scientific presentations. This is a careful discussion of principles stated in thoroughly acceptable scientific form, yet in a manner that makes it possible for the reader who has no scientific training to understand it. Only high school algebra has been used in explaining the nature of classical physics and relativity, and simple experiments and diagrams are used to illustrate each step. The layman and the beginning student in physics will find this an immensely valuable and usable introduction to relativity.

First edition, offprint issue. Einstein and Infeld demonstrate that "field equations alone suffice as a basis for solving the problem of motion in general relativistic theory, since the Einstein equations not only determine how particles must respond to gravitational forces, but also contain the information necessary to describe those forces" (Calaprice, p. 323).

First edition in English, first impression, marking the first appearance of any of Einstein's works in English and including a new chapter written by Einstein for this edition. It was first published in German in 1916 and is here translated from the third edition of 1918. Methuen urged Lawson to make the translation "as intelligible as possible to the ordinary man. There is complete ignorance in the public mind as to what Relativity means. A good many people seem to think that the book deals with the relations between the sexes" (Buchwald, Sauer, & Kennefick, p. 326). The additional chapter (Appendix III) for this edition was written by Einstein in only a few hours, after Lawson suggested the book would be more accessible if its author could provide a proof of the general theory.

First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' (see Weil no. 21 and Dictionary of Scientific Biography, vol. 4 pp.323 for examples). However, in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' [the offered paper] which predates the former mentioned by six months, Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade, pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper, 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2, and concluded that the mass of a body is a measure of its energy content, e.g., that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity. Then finally in the 1907 paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie.' [the offered paper] Einstein makes the decisive step of assuming that all mass has energy. On page 382 Einstein considers the total energy of a moving mass point as the sum of its kinetic energy and its rest energy. In classical mechanics it is most convenient to set the second term to zero but in relativistic mechanics one obtains the simplest expression by setting the rest energy equal to mc2. Einstein then continues to show that this stipulation cannot lead to a contradiction in any relativistic argument. In a footnote on page 382 Einstein states for the first time the equation E=mc2 and mentions that this equation is the expression of the principle of the equivalence of mass and energy - see Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.The volume contains another paper by Einstein "Bemerkungen zu der Notiz von Hrn.

[1950]. 8vo. Original proof-copy (of the latest stage, presumably final proof, in the same format as the printed version and with no corrections), printed on rectos and versos. Stapled twice in left margin. A few marginal creases. A (proof-) number to upper left corner in red ink (297). Pp. 109-148 + tipped-in errata slip at p. 147. Very rare original proof-copy of the two highly important appendices for Einstein's "The Meaning of Relativity", third edition, 1950, the second appendix being one of the most important pieces Einstein ever wrote, namely the appendix "in which he described his most recent work on unification" (Pais), and the work which was hailed by The New York Times under the heading "New Einstein theory gives a master key to the universe". The first appendix, which appeared for the second edition of the work, remained unchanged throughout the history of "the Meaning of Relativity" and was written because "Since the first edition of this little book some advances have been made in the theory of relativity. [.] The first step forward is the conclusive demonstration of the existence of the red shift of the spectral lines by the (negative) gravitational potential of the place of origin" [.] A second step forward, which will be mentioned briefly, concerns the law of motion of a gravitating body." [.] A third step forward, concerning the so-called "cosmologic problem," wiil be considered here in detail." (pp. 109-10). The present 40 pages constitute the final proof-copy of the entire appendices I and II to the Generalized Theory of Gravitation, exactly as they appeared in the third edition (Princeton in 1950). Einstein's "The Meaning of Relativity" was originally published in 1922, on the basis of his "Vier Vorlesungen ueber Relativitetstheorie" given at Princeton in 1921. A second edition, with an appendix (appendix I) appeared in 1945 (several issues and editions of this appeared also), and in 1949 the third edition, with the seminal Appendix II printed for the first time, appears (also appeared in 1950, in Princeton). In 1950 a revised edition of the third edition appears, having Appendix II slightly revised, and in 1953 the heavily revised fourth edition appears. THIS IS THE PROOF-COPY OF APPENDICES I AND II FOR THE "THIRD EDITION, INCLUDING THE GENERALIZED THEORY OF GRAVITATION" (PRINCETON, 1950). The main focus of the work throughout all these editions of the work since 1949 is Appendix II, which deals with Einstein's main interest, the generalization of the Gravitation Theory, which was to unite the general theory of relativity with electromagnetism, recovering an approximation for quantum theory, and presenting us with a theory to explain the universe as a unified entity, the ultimate goal for the greatest physicist that ever lived. "This was Einstein's ultimate response to the mechanical-electromagnetic crisis in physical theory he had first talked about in the opening of his 1905 light quantum-paper." (Nandor, in D.S.B., p. 330). It was indeed Einstein's aim to provide an explanation of the universe through his unified field theory, although he was well aware that his sort of field theory might not exist. However, even the establishing of the non-existence of it could bring us closer to an explanation than we had ever been before. There is no topic of greater importance to Einstein than his theory of unification. "In 1949 Einstein wrote a new appendix for the third edition of his "The Meaning of Relativity" in which he described his most recent work on unification. It was none of his doing that a page of his manuscript appeared on the front page of "The New York Times" under the heading "New Einstein theory gives a master key to the universe". He refused to see reporters and asked Helen Dukas to relay this message to them: "Come back and see me in twenty years"." (Pais, p. 350).

Stockholm, Nordstedt & Fils, 1923. Orig. printed wrappers. Offprint from "Les Prix Nobel en 1921-1922". Pp. 1-10. Fine and clean. First edition in the scarce offprint version of Einsteins Nobel lecture. The paper presents the Nobel lecture delivered in Göteborg on July 11, 1923. Because Einstein did not deliver the lecture at the same time as he received the award, it did not concern the prize topic, which was "for his attainments in mathematical physics and especially for his discovery of the law of the photoelectrical effect."In relation to his Nobel Prize, Einstein would have preferred to speak on unified field theory, but he followed Arrhenius proposal "but it is certain that one would be most grateful for a lecture about your relativity theory." On a very hot day in July, Einstein, dressed in a black redingote, addressed an audience of about two thousand in the Jubilee Hall in Göteborg on "basic ideas and problems of the theory of relativity." King Gustav V, who was present, had a pleasant chat with Einstein afterwards. Einstein later gave a second, more technical lecture at Chalmers Technical Institute for about fifty members of the Science Society."(Pais, pp. 504-5).Weil: 135. - Boni: 136.
