Limited to 3000 Copies in the original glassine outer wrapper. 8vo. 40 pp. With black and white photographs of Albert Einstein and Frank Back. A fine copy in handmade decorative paper covered boards printed glossy paper label to the upper cover. The volume dedicated to Albert Einstein is the only book written by Dr. Frank Back "The Father of the Zoom Lens" and creator of the first widely used zoom lenses for film and television. Dr. Back a close friend of Albert Einstein was persuaded by Einstein to take the trip commemorated in this beautifully produced volume in order to capture the total eclipse of the sun which occurred on June 20 1955. Dr. Back intended to provide conclusive evidence for Einstein's theory of relativity by calculating the optical distortion if any of starlight caused by the sun's gravity. In 1919 Einstein's general relativity principles were supported by observations of a solar eclipse. The two scientists conferred on the project for over a year. Armed with a special Zoomar designed and built wide-angle solar-eclipse spectrograph Dr. Back was off to the Philippine Islands to board a military jet and chase the eclipse. Einstein however died while Back was on his way to Manila. Unable to report the excursion to his friend Dr. Back dedicated this book to his memory. <br /> In a TBCL dark green cloth slipcase.

19286594Paris: Gauthier Villars 1928. First edition. <p>First edition rare in the original printed wrappers of the proceedings of the Fifth Solvay Congress 1927-the most celebrated of the Solvay conferences and the setting in which the Bohr-Einstein debate over the consistency and completeness of quantum mechanics first took public programmatic form. Convened under the banner "Electrons and Photons" the meeting brought together nearly all the principal architects of the old and the new quantum theory; seventeen of the twenty-nine participants were or became Nobel Prize laureates.</p>. The Bohr-Einstein Debate Begins. <p>First edition rare in the original printed wrappers of the proceedings of the fifth Solvay Congress where the debate between Bohr and Einstein on the consistency and completeness of quantum mechanics began. It was at this the most famous of the Solvay conferences that Einstein disenchanted with Heisenberg's uncertainly principle made his famous remark that "God does not play dice" to which Niels Bohr replied "Einstein stop telling God what to do!" Seventeen of the twenty-nine attendees which included nearly all the principal architects of the old and the new quantum theory were or became Nobel Prize winners. "The three and a half years since the fourth Solvay Conference . were marked by enormous progress in quantum physics. Partly based on discoveries and ideas that had been available already before 1924 − such as the Compton effect and matter waves − the new atomic theory had arisen which did more than throw new light on the difficulties discussed at the 1924 conference: quantum or wave mechanics went right to the heart of the problems posed by atomic phenomena. The two subjects put programmatically into the title of the fifth Solvay Conference − electrons and photons − designated the crucial points of interest because 'electrons' also stood for the smallest massive constituents of matter and they now became associated with waves and 'photons' a name given only recently in October 1926 by the physical chemist Gilbert N. Lewis to Einstein's light-quanta characterized the quantum-theoretical aspect of electromagnetic radiation. It was the declared intention of the Scientific Committee of the Institut International dePhysique Solvay to contribute by scientific reports and discussions about them to the clarification of the scientific concepts in the physics of the day. In retrospect one may indeed attribute an important success to the 1927 Solvay Conference in marking the completion of the ideas that had first been discussed in the international physics community sixteen years previously at the first Solvay Conference of 1911" Mehra & Rechenberg pp. 233-4. Following a 'Notice nécrologique' by Lorentz the present volume contains the following reports and discussions about them by the participants all articles in French: 'The Intensity of the Reflection of X-rays' by Bragg; 'Disagreement between Experience and the Electromagnetic Theory of Radiation' by Compton; 'The New Dynamics of Quanta' by de Broglie;<br /> 'The Mechanics of Quanta' by Born and Heisenberg; 'The Mechanics of Waves' by Schrödinger;<br /> 'The Quantum Postulate and the New Development of Atomic Theory' by Bohr. No copies located in auction records.</p> <br /> <p>In 1911 the Belgian industrialist Ernest Solvay invited a group of the world's most prominent physicists including Einstein Planck Lorentz Sommerfeld Rutherford and Marie Curie to participate in a scientific conference on the difficulties of reconciling classical physics with quantum theory. The conference "set the style for a new type of scientific meetings in which a select group of the most well informed experts in a given field would meet to discuss the problems at its frontiers and would seek to define the steps for their solution" Mehra Solvay Conferences p. xv. The first Solvay Conference-widely considered a turning point in the history of modern physics-was so successful that in the following year Solvay established a foundation now known as the International Solvay Institutes for Physics and Chemistry "to encourage the researches which would extend and deepen the knowledge of natural phenomena" ibid. and to sponsor further conferences. The next two Solvay Conferences met in 1913 and 1921; subsequent conferences have been held every three years except during wartime.</p> <br /> <p>"From amongst the members of the Scientific Committee of the 1927 Congress two had already played a leading role in 1911: the Chairman Hendrik Lorentz and Albert Einstein; the latter had presented then the most revolutionary report on the light quantum. In spring 1926 in the early stage of preparing for the new conference Lorentz again requested Einstein to write a report. The latter answered promptly: 'If you wish that I take over the report on quantum statistics I shall do so with pleasure; because without being in great difficulty I shall never say "no" to you' Einstein to Lorentz 1 May 1926 . On 17 June 1927 Einstein wrote to Lorentz: 'I recall having committed myself to you to give a report on quantum statistics at the Solvay Conference. After much reflection back and forth I came to the conclusion that I am not competent for giving such a report in a way which really corresponds to the state of the thing. The reason is that I have not been able to participate as intensively in the modern development of quantum theory as would be necessary for that purpose. This is in part because I have on the whole too little receptive talent for fully following the stormy developments in part also because I do not approve of the purely statistical way of thinking on which the new theory is founded .' As a substitute speaker for the topic assigned to him he proposed either Enrico Fermi from Italy or Paul Langevin from France. Ultimately however neither of them gave the report on Einstein's subject. Instead Niels Bohr agreed to contribute a report on a different topic: namely on his latest considerations on the problem of the interpretation of quantum mechanics.</p> <br /> <p>"The rapporteurs at the fifth Solvay Conference fell into three groups: the experimentalists Bragg and Compton; the theoreticians advocating the Gottingen-Cambridge-Copenhagen versions of quantum mechanics − Bohr Born and Heisenberg; and those of the wave-mechanical camp − de Broglie and Schrodinger.</p> <br /> <p>"The selection of Arthur Holly Compton seemed to be most appropriate because the Compton effect − discovered in late 1922 − had been one of the crucial results triggering the entire development which ended with the new atomic theory by providing Einstein's light-quantum hypothesis of 1905 a firm experimental foundation. Since its discovery and even more so after the refutation of the Bohr-Kramers-Slater theory of radiation . Einstein's fundamental light-quantum conception . became a physical reality. Compton's report dwelt on the conceptual consequences rather than on experimental details. In particular he addressed the questions of the aether and of electromagnetic waves on the one hand and the phenomena contradicting the classical wave concepts such as the photoelectric effect X-ray diffraction certain electron-recoil effects observed by C. T. R. Wilson and W. Bothe in 1923 and the individual interaction between radiation-quanta and electrons i.e. the Compton effect. Compton showed also in some detail how the Bohr-Kramers-Slater theory failed to account for these observations.</p> <br /> <p>"The report of William Lawrence Bragg a regular participant in the Solvay Conferences since 1913 appeared to address on first inspection less central points. However from his presentation of the material on reflection of X-rays one easily recognizes the strategy of the Scientific Committee of the Conference: Bragg had to take over the task of stressing those radiation phenomena that could be described by the wave theory namely the diffraction of X-rays by crystal lattices. Consequently he gave the story from Laue's discovery in 1912 over the subsequent work of his father William Henry Bragg and himself to the later investigations of Paul Ewald William Duane and others. Bragg demonstrated in detail how the old and the new wave theories worked to describe the phenomena of diffraction and refraction of X-rays. In the discussion of Bragg's report Hendrik Kramers presented at some length the recent development of the dispersion theory by himself and Ralph Kronig.</p> <br /> <p>"Both experimental reports served as a firm basis for the discussion of the theoretical concepts which provided the central theme of the conference. This significance was shown by the discussions immediately following them. Compton's talk especially gave rise to a lively exchange of ideas and arguments in which besides the experimentalists e.g. Bragg Madame Curie O. W. Richardson and C. T. R. Wilson almost all of the theoretical experts present participated i.e. Bohr Born Debye Dirac Ehrenfest Lorentz Pauli and Schrödinger − with one important exception: according to the published proceedings of the fifth Solvay Conference offered here Einstein remained silent after the presentations of Compton and Bragg .</p> <br /> <p>"The presentation of the theoretical reports at the Solvay Conference proceeded by following the historical order in which the ideas had been published between 1923 and 1926: thus de Broglie's talk came first then Born and Heisenberg's followed by Schrödinger's and finally Bohr's .</p> <br /> <p>"In the course of the year 1927 the Copenhagen physicists Heisenberg among them clarified their ideas on the interpretation of atomic phenomena. Although they admitted the existence and persistence of statistical relations in quantum mechanics they searched for − and succeeded in − formulating principles that in their opinion at least provided the deeper reason for these statistical features: the uncertainty relations and the complementarity principle. In spite of this difference in attitude toward what they regarded as truly fundamental and actually derived Heisenberg felt no difficulty in preparing a joint Solvay report together with his former teacher Max Born. Their report provided a view of the work performed in Göttingen and Cambridge in establishing quantum mechanics with chapters on matrix mechanics and its transformation into wave mechanics I the physical interpretation of the theory II and the uncertainty principle III. The balance in representing the main interests of the two authors was achieved insofar as Section II dealt with Born's statistical interpretation and Section III with Heisenberg's limitation on measurements in quantum mechanics. Moreover the Born-Heisenberg report also signaled the agreement reached by Heisenberg and Niels Bohr during the summer of 1927 .</p> <br /> <p>"Louis de Broglie entitled his report 'The new dynamics of quanta'; he covered the story from his first ideas on matter waves in 1923-24 to the advent of Schrödinger's equation in 1926 and on to the new pilot-wave theory in 1927. He further applied the pilot-wave theory to the problem of the hydrogen atom and claimed that the treatment yielded an easier understanding of the actual situation; finally he spoke about the experimental verification of matter waves obtained recently in the experiments of Clinton Joseph Davisson and Lester Halbert Germer and George Paget Thomson and Alexander Reid . Erwin Schrödinger on the other hand concentrated on the mathematical aspects of his wave-mechanical scheme the time-independent as well as the time-dependent equations the formal equivalence of wave mechanics to the Born-Heisenberg-Jordan matrix scheme and the relativistic wave equation. At the end of the conference Niels Bohr presented a modified version of his Como lecture under the title 'The Quantum Postulate and the New Development of Atomic Theory' .</p> <br /> <p>"Although the Born-Heisenberg and Schrödinger reports provoked only technical questions that of de Broglie and especially the one of Bohr stimulated some conceptual discussion. Thus Lorentz asked de Broglie how the old Sommerfeld quantum conditions could be obtained from the new matter-wave ideas and Pauli provided an appropriate calculation using the conservation law for the relativistic electric current; also Leon Brillouin illustrated some 'optical' applications of matter waves. Finally Bohr's report at the end provided the proper start for a very excited 'General Discussion of the New Ideas Put Forward.'</p> <br /> <p>"Upon an opening reflection of Hendrik Lorentz − who expressed some reservation with respect to the new pictures of electrons in quantum and wave-mechanics − and a technical illustration of Max Born for dealing with many-electron systems in the probability scheme Einstein addressed an elementary problem in the physical interpretation of the theory. He suggested in particular to consider an electron passing through a slit in a screen and to discuss the diffraction phenomena obtained. He claimed that 'with respect to quantum mechanics one can take two standpoints regarding its validity' namely:</p> <br /> <p>Interpretation I: The de Broglie-Schrodinger waves do not correspond to a single electron but to an electron cloud extended in space. The theory does not give then any information about an ensemble of an infinity of elementary processes.</p> <br /> <p>Interpretation II: The theory claims to be a complete theory of individual processes. Each particle which moves towards the screen as far as one can determine from its position and velocity is described by a de Broglie-Schrödinger wave packet of small length and small aperture. This wave packet is diffracted and after diffraction arrives partly at the film where it is registered in a resolved state Einstein in the present work pp. 254-5.</p> <br /> <p>"Evidently Interpretation II went beyond I and even included the latter; it also implied that the conservation laws especially for momentum were valid for individual atomic processes thus explaining the Bothe-Geiger experiment as well as other experiments. Still Einstein also objected to this interpretation because: 'If Ψ2 where Ψ is the wave function were simply considered as the probability for a particle to be at a place at the definite instant it might happen that one and the same elementary process would cause an action at two or more places on the screen' which would imply an action-at-a-distance hence a violation of the relativity postulate. The only way out of this difficulty had to be sought with de Broglie in further attempts to localize the microscopic particle. Einstein claimed further that the multidimensional phase space assumed for many-particle systems in quantum or wave mechanics and the corresponding permutation properties contradicted the new statistical results.</p> <br /> <p>"Although Lorentz tried to illuminate the statistical argument further Wolfgang Pauli contradicted Einstein by referring to the recent work of Paul Dirac Pascual Jordan and Oskar Klein on field quantization. He also refuted another argument of Einstein's that the range of forces in quantum mechanics might create problems by pointing to the work of Walter Heitler and Fritz London on molecular binding. Dirac at first supported Pauli's plea; then he stated his 'opinion about determinism and the significance of numbers which occur in the calculus of quantum theory' notably: 'In the classical theory one starts from certain numbers which completely specify the initial state of the system and one deduces certain numbers which specify the final state. This determination applies only to an isolated system' Dirac in the present work p. 261.</p> <br /> <p>"Now according to Bohr isolated systems are by definition unobservable because any observation must disturb the system; as a result already 'the classical deterministic theory cannot be defended.' Furthermore: 'In the quantum theory one starts from certain numbers from which one deduces certain other numbers . The perturbations which an observer inflicts on a system in order to observe it are directly subject to his control and are acts of his free will. It is exclusively the numbers which describe these acts of free choice that can be taken as initial numbers for a calculation in the quantum theory. Other numbers specifying the initial state of the system are fundamentally unobservable and do not appear in the quantum-theoretical treatment' Dirac loc. cit. .</p> <br /> <p>"After Dirac had illustrated his interpretation of the quantum-mechanical process and its observation in the case of a sample collision experiment Heisenberg remarked that he did 'not agree' with Dirac saying 'that in the experiment described nature makes a choice' because: 'Even if you place yourself very far from your scattering material and if you measure after a very long time you can obtain interference by taking two mirrors. If nature were to make a choice it would be difficult to imagine how the interference can be produced. Evidently we can say that nature's choice can never be known until the decisive experiment has been done; for this reason we cannot make any real objection to this choice because the expression "nature makes a choice" does not have any physical consequences. I would say as I have done in my latest paper that the observer himself makes the choice because it is not until the moment when the observation is made that the "choice" becomes a physical reality and that the phase relation in the waves i.e. the ability to interfere is destroyed' Heisenberg in the present work pp. 264-5 .</p> <br /> <p>"The differences in interpretation among the main pioneers of quantum mechanics that showed in this exchange notably between Bohr and Heisenberg and Dirac would become more pronounced in the future .</p> <br /> <p>"In the recollections of some participants of the fifth Solvay Conference the exchange between Bohr and Einstein on fundamental questions concerning the interpretation of quantum mechanics stands out vividly. Thus Bohr after more than twenty years wrote a detailed account of his 'Discussions with Einstein on Epistemological Problems in Atomic Theory' where he introduced the important part dealing with the 1927 exchange by saying: 'At the general discussions in Como we all missed the presence of Einstein but soon after in October 1927 I had the opportunity to meet him in Brussels at the Fifth Physical Conference of the Solvay Institute . At the Solvay meetings Einstein had from their beginning been a most prominent figure and several of us came to the Conference with great anticipations to learn his reaction to the latest stage of the development which to our view went far in clarifying the problems which he had himself from the outset elicited so ingeniously. During the discussions where the whole subject was reviewed by contributions from many sides Einstein expressed however a deep concern over the extent to which causal account in space and time was abandoned in quantum mechanics.'</p> <br /> <p>"The official discussions referred to above throw light on some of the exchanges on the questions that did interest Einstein although Bohr's participation in them does not seem to have been so active. For example no answer from Bohr to Einstein's analysis of the electron's passage through a slit or screen was recorded. Bohr just made some notes which are to be found in his files and as Louis de Broglie recalled: 'Also Einstein said hardly anything beyond presenting a very simple objection to the probability interpretation. Then he fell silent'. However Heisenberg took away quite a different impression from the conference and decades later he wrote enthusiastically: 'The discussions were soon focused upon a duel between Einstein and Bohr on the question as to what extent atomic theory in its present form could be considered to be the final solution of the difficulties which had been discussed for several decades. We generally met already at breakfast in the hotel and Einstein began to describe an ideal Gedanken experiment in which he thought the inner contradictions of the Copenhagen interpretation were especially clearly visible. Einstein Bohr and I walked together from the hotel to the conference building and I listened to the lively discussion between those two people whose philosophical attitudes were so different and from time to time I added a remark on the structure of the mathematical formalism. During the meeting and particularly in the pauses we younger people mostly Pauli and I tried to analyze Einstein's experiment and at lunch time the discussions continued between Bohr and the others from Copenhagen. Bohr had usually finished the complete analysis of the ideal experiment by late afternoon and would show it to Einstein at the supper table. Einstein had no good objection to this analysis but in his heart he was not convinced. Bohr's friend Ehrenfest who was also a close friend of Einstein said to him 'I am ashamed of you Einstein! You put yourself here just in the same position as your opponents in their futile attempts to refute your relativity theory."</p> <br /> <p>"Thus by piecing together the contemporary documents of 1927 with the later recollections of the participants a fairly consistent historical picture of the great epistemological debate between Bohr and Einstein has arisen. The fifth Solvay Conference would not end this debate however. Both participants returned to the problems involved again and again especially at the sixth Solvay Conference in 1930 and a few years later in 1935. Still quantum mechanics had already scored the main points in its favour. 'The most important success of the Brussels meeting was that we could see that against any objections against any attempts to disprove the theory we could get along with it' Heisenberg summarized the result in an interview in 1963 and added: 'At that time in 1927 it was practically Bohr Pauli and myself perhaps just the three of us. That very soon spread out'" Mehra & Rechenberg The Historical Development of Quantum Theory vol. 6 pp. 232-256.</p> <br /> <p>For an English translation and detailed analysis of the conference reports see Bacciagaluppi & Valentini Quantum Theory at the Crossroads.

193160051931. First edition. <p>An important group of photographs documenting Einstein's visit to Caltech. The main purpose of the visit was to discuss Edwin Hubble's observations made in 1929 with the 100-inch telescope at the Mount Wilson Observatory which showed that light from distant nebulae galaxies was red-shifted indicating that the universe was expanding. Einstein had believed that the universe is static and had introduced his 'cosmological constant' into his equations of general relativity to allow for a static solution. When Einstein met Hubble at the Mount Wilson Observatory in January and February 1931 he was visibly moved with Hubble's discovery and reportedly said with tears in his eyes that "It was the most beautiful and satisfying interpretation of astronomical science." In light of the new evidence Einstein published a paper two months later renouncing the concept of a cosmological constant whose invention Einstein denounced as "the greatest blunder of my life."</p>. 'the greatest blunder of my life'. <p>An important group of photographs documenting Einstein's second visit to America and his first to the California Institute of Technology which began at the end of December 1930. The main purpose of the visit was to discuss Edwin Hubble's observations made in 1929 with the 100-inch telescope at the Mount Wilson Observatory then the largest telescope in the world which showed that light from distant nebulae galaxies was red-shifted indicating that the universe was expanding. Einstein had believed that the universe is static and had introduced his 'cosmological constant' into his equations of general relativity to allow for a static solution. When Einstein met Hubble at the Mount Wilson Observatory in January and February 1931 he was visibly moved with Hubble's discovery and reportedly said with tears in his eyes that "It was the most beautiful and satisfying interpretation of astronomical science." In light of the new evidence Einstein published a paper two months later renouncing the concept of a cosmological constant whose invention Einstein denounced as "the greatest blunder of my life." Einstein was accompanied on his visit by Walther Mayer 1887-1948 who had been appointed as his mathematical assistant in 1929. Mayer and Einstein worked together on several approaches towards a unified field theory. "On the way over Einstein and his mathematical calculator Walther Mayer holed up working on revisions to his unified field theory in an upper-deck suite with a sailor guarding the door" Isaacson p. 368. Two of the photographs are of Einstein at Mount Wilson one with Mayer and the observatory's director Walter Adams 1876-1956 who had confirmed Einstein's prediction of the gravitational red-shift although his observations were later shown to be faulty; the other with Mayer and solar physicist Charles St. John 1857-1935 who had assisted Hubble with his red-shift observations. Another photograph shows Einstein between fellow Nobel Laureates Albert Michelson 1852-1931 and Robert Millikan 1868-1953 Caltech's "chairman of the executive council" effectively its president. Together with Edward Morley Michelson had in 1887 carried out the famous Michelson-Morley experiment which failed to detect evidence of the existence of the luminiferous ether; this provided crucial evidence for the early acceptance of special relativity. On this trip Einstein "paid tribute to the aging Michelson carefully praising his famous experiments that detected no ether drift without explicitly saying that they were a basis for his special theory of relativity" Isaacson p. 372. </p> <br /> <p>"In the early 1930s Einstein came to California specifically to consult with scientists at the California Institute of Technology. Few members of the general public understood the nature of his visits but they idolized him all the same. From the moment his boat docked in San Diego on December 31 1930 the reception accorded him by Californians was one part show business one part hero worship and one part genuine affection. Groups of children dressed in blue and white middies serenaded him and thrust wreaths of flowers into his hands two bands struck up tunes and in Los Angeles a theatrical group the Yale Puppeteers opened a play called Mr. Noah in which the ark landed on Mt. Wilson instead of on Mt. Ararat .</p> <br /> <p>"As early as 1913 Einstein was looking for experimental verification for the correctness of his theory of general relativity and he had been in correspondence with Caltech's George Ellery Hale asking him to make an astronomical measurement. He was anxious to know if Hale could detect the influence of the sun's gravitation field upon a light ray. Hale replied that in order to try he needed a solar eclipse. The experiment was finally carried out in 1919 by two British expedition teams and again in 1922 by an American team of astronomers - and it did confirm the theory of general relativity.</p> <br /> <p>"There were cosmological implications in this theory and they attracted a lot of attention in the 1920s and 1930s - nowhere more than at Caltech. Millikan had been urging Einstein to visit the campus for some time and in the fall of 1930 he agreed to spend the winter quarter in Pasadena. Not only would he be able to discuss his theory and its interpretation with distinguished scientists; he would also be meeting old friends again - Richard Tolman the cosmologist; Paul Epstein the theoretical physicist; and Theodore von Karman the aerodynamicist .</p> <br /> <p>"The new Athenaeum at Caltech was the setting for many dinners to honor Einstein. At the first on January 15 1931 the guests included the physicist and Nobel Laureate A. A. Michelson and 200 members of the California Institute Associates. Several weeks later a second dinner was held at which all the astronomers from the Institute and the Mt. Wilson Observatory were present. Edwin Hubble was there as was Charles E. St. John who verified the third prediction of the theory of general relativity the gravitational red-shift. Colleagues came from Berkeley including Tolman's close friend and co-author G. N. Lewis who wrote to say he was coming with a friend - though not without some mildly humorous trepidation. As he put it in his letter to Tolman: 'I have just accepted an invitation from Oppenheimer to drive me down. Do you think I should take out accident insurance'</p> <br /> <p>"Einstein was not without a sense of humor himself. At a farewell luncheon in his honor on February 24 1931 which was sponsored by the Pasadena Chamber of Commerce he said: "I want to thank the extraordinary group of scholars in the fields of physics and astronomy who have afforded me glimpses of their work. They have conducted me not only into the world of atoms and crystals but also to the surface of the sun and into the outermost depths of space. There I saw worlds which are flying away from us with incomprehensible rapidity in spite of the fact that their inhabitants do not know us well enough to justify any such action'" Goodstein.</p> <br /> <p>"Millikan was a physicist who had won the Nobel Prize in 1923 for having 'verified experimentally Einstein's all-important photoelectric equation.' He likewise verified Einstein's interpretation of Brownian motion. So it was understandable that as he was building Caltech into one of the world's pre-eminent scientific institutions he worked diligently to bring Einstein there.</p> <br /> <p>"Despite al they had in common Millikan and Einstein were different enough in their personal outlooks that they were destined to have an awkward relationship. Millikan was so conservative scientifically that he resisted Einstein's interpretation of the photoelectric effect and his dismissal of the ether even after they were apparently verified by his own experiments. And he was even more conservative politically. A robust and athletic son of an Iowa preacher he had a penchant for patriotic militarism that was as pronounced as Einstein's aversion to it" Isaacson p. 373. </p> <br /> <p>"To physics posterity Viennese mathematician Walther Mayer is mostly known as 'Einstein's calculator'. He had apparently been called that at the California Institute of Technology in Pasadena which Einstein and Mayer visited together in the winter of 1930/31. It is true that in order to advance in his studies to construct a unified field theory Einstein relied on the expertise of mathematicians. With his unified field theory Einstein attempted to formally join his own theory of general relativity with Maxwell's electromagnetism.</p> <br /> <p>"When Einstein was looking for a new mathematics assistant in 1929 Mayer was hired on the recommendation of eminent mathematician Richard von Mises. Like Einstein von Mises at that time held a professorship in Berlin. Walther Mayer then served as private lecturer at the University of Vienna finishing the second volume of a very well received textbook series on differential geometry which he co-authored with fellow Viennese mathematician Adalbert Duschek. Subsequently Mayer and Einstein worked together on several approaches towards a unified field theory consisting of 1 the analysis of solutions to Einstein's so-called distant teleparallelism approach 2 the invention of a variant of the Kaluza-Klein theory in which not space-time but attached vector spaces are 5-dimensional and finally 3 the construction of a formalism they referred to as "semi-vectors" for interpreting Dirac-spinors in simpler classical field-theoretical terms and reformulating the Dirac equation accordingly. Their joint work was published in 7 papers over a period of roughly four years 1930-1934 .</p> <br /> <p>"While being humbly appreciative of the vital improvement that Einstein brought to his career Mayer was at the same time also quite unhappy about his role as Einstein's 'appendage'. Einstein however was aware of and respected this sentiment of Mayer's: When he bargained his Princeton position with Abraham Flexner a founding director of Princeton's Institute for Advanced Study he insisted on an independent professorship for Mayer as well. After some back and forth this was indeed granted at the last minute. However the question of Mayer's legitimacy as an independent professor at Princeton surfaced again after their arrival. Feeling unwelcomed and not sufficiently supported by Einstein Mayer finally ended their collaboration after just one further joint paper in 1934. He felt that his career would be advanced best if from now on he would focus entirely on his own studies in pure mathematics. In the end Mayer was able to retain his tenure at Princeton for the rest of his life but he subsequently appeared to have wished to no longer be associated with work on unified field theory. On the outside Einstein and Mayer remained in friendly contact while Einstein found new collaborators. The ones immediately succeeding Walther Mayer at Princeton were Boris Podolsky and Nathan Rosen" Lessel.</p> <br /> <p>The photographs are accompanied by a number of letters from Mayer to his brother Arthur in Austria discussing Einstein's work Hitler and the Nazis. Mayer was Jewish and it was only through Einstein's intervention that he was given the title of professor at the University of Vienna. Mayer immediately took a leave of absence from this position to continue his collaboration with Einstein when he had returned to Berlin.</p> <br /> <p>At a press conference on his arrival in New York Einstein was asked "'What do you think of Adolf Hitler' Einstein replied 'He is living on the empty stomach of Germany. As soon as economic conditions improve he will no longer be important'" Isaacson p. 369. "On the day he left New York Einstein revised slightly one of the statements he had made on his arrival. Asked again about Hitler he declared that if the Nazis were ever able to gain control he would consider leaving Germany" ibid. p. 371. In April 1933 Einstein discovered that the new German government had passed laws barring Jews from holding any official positions including teaching at universities. He left Germany in summer 1933 and took up a position at the Institute for Advanced Study in Princeton despite Millikan's efforts to lure him to Caltech. He remained at the Institute until his death in 1955.</p> <br /> <p>Goodstein 'Albert Einstein in California' Engineering and Science May-June 1979 pp. 17-19 - Isaacson Einstein.

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. <br/><br/><em>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. </em> unknown

In addition to her acting career Mellon had been involved in creative and cultural work connected to Haiti launching micro-businesses and continuing the work of her late first husband William Larimer Mellon III with Hôpital Albert Schweitzer. In very good condition. Albert Einstein developed the general theory of relativity one of the two pillars of modern physics alongside quantum mechanics. Einstein's work is also known for its influence on the philosophy of science. Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics for his "services to theoretical physics" in particular his discovery of the law of the photoelectric effect a pivotal step in the evolution of quantum theory David Bodanis. unknown

19182839London: Fleetway Press 1918. FIRST EDITION. Original wrappers. Fine. THE FIRST INTRODUCTION OF EINSTEIN'S GENERAL RELATIVITY TO THE ENGLISH-SPEAKING WORLD. The groundbreaking first edition 1918 with the second edition 1920 containing the account of Eddington's 1919 expedition proving Einstein's theory both in original wrappers. "Einstein's discovery of the General Theory of Relativity was communicated to the Berlin Academy of Sciences in 1915. Because of the First World War direct communication with physicists in Germany was not possible but the papers were forwarded to Eddington who was then Secretary of the Royal Astronomical Society by Willem de Sitter a personal friend of Eddington's in neutral Holland. The theory is of considerable mathematical complexity but as Einstein stated in the last paragraph of his paper 'scarcely anyone who has fully understood this theory can escape from its magic'. Eddington was the ideal expositor of these ideas in English and within 2 years had written his Report on the Relativity Theory of Gravitation for the Physical Society of London" Malcolm Longair "Bending Space-time". <br /> <br /> The second edition is notable for containing a new preface that discusses the results of the "eclipse expedition" led by Eddington that verified General Relativity and catapulted Einstein into world-wide fame. This preface precedes Eddington's full report in the Philosophical Transactions.<br /> <br /> Provenance: Almost certainly Nobel Prize winning physicist's Charles Glover Barkla's copy of the 1918 report with an original 1918 receipt in Barkla's name laid in.
