‎First edition, in the scarce author's presentation offprint issue, of this important paper, which contains Einstein's theories on wave-particle duality and German physicist Rupp's work on the same subject, seemingly to corroborating Einstein's theories. Rupp's experimental results later turned out to have been falsifications, and today he is mainly known as the protagonist in one of the biggest scandals in physics in the 20th century.Rupp published a number of papers on the interference properties of light emitted by canal ray sources. These articles, particularly the present that came into being in close collaboration with Albert Einstein, attracted quite a lot of attention, as they probed the wave versus particle nature of light. They also significantly propelled Rupp's career, even though they were considered highly controversial to begin with.In April 1926, Albert Einstein proposed to Emil Rupp to carry out two experiments that were to prove the wave nature of light versus the particle nature of light: the so-called 'Wire Grid Experiment' and the 'Rotated Mirror Experiment', experiments that Einstein had worked on theoretically and now would like to gain confirmation of through experiments. Rupp, at the time regarded as one of the most important and most competent experimental physicists, gladly took up the challenge. Rupp's observations - though highly controversial - confirmed Einstein's theory. Due to the surprising outcome of the experiments, Einstein was interested in exactly how it they were conducted, as Rupp's initial descriptions did not convince him that the results were feasible.""Rupp stood by his observations and suggested yet other circumstances that might explain them. Did Einstein now realize that there was something rather dubious about Rupp's work? He had seen him change his data repeatedly-and each time in better accordance with his own criticism, and on one occasion in no less than two days. He had had to accept that Rupp claimed to earlier have ""unknowingly"" or ""unconsciously"" rotated a mirror, and he will likely have seen that Rupp's work was highly controversial amongst experimentalists, leading to very public criticism in Die Naturwissenschaften. He himself was now also convinced that, in fact, Rupp's results were incomprehensible. So, did Einstein choose to suspend the publication of Rupp's piece, so that an additional round of checks and balances could take place? The answer is no: Rupp's paper was presented by Einstein to the Prussian Academy in a session on 21 October 1926, and it appeared in print in the Academy's proceedings in November of 1926-the articles by Einstein and Rupp came out back to back, and reprints circulated with both papers bound together, with a joint cover page that displayed both titles. Einstein referred in his article to Rupp's claims and he had even written the abstract of Rupp's paper"" (Dongen: ""Emil Rupp, Albert Einstein and the Canal Ray Experiments on Wave-Particle"").The first clear indication that Rupp's work was impossible to recreate came in 1930 in a paper published by Staub - nothing was wrong with Einstein's theory but Rupp's work was simply impossible: ""Rupp immediately set out to respond to Straub's publication. On 12 July 1930 he sent a first draft to Einstein, to whom he also announced his intention of redoing his canal ray experiments-Straub was dismissed as a clumsy graduate student with a lousy apparatus. Einstein suggested inviting Straub once Rupp had his experiment up and running again, but cautioned him not to engage the polemic in too sharp a tone"". Rupp managed to convince the physics society and continued to publish the new few years. In 1934 various different physicians pointed out that Rupp's work was impossible to recreate, and in 1935 the final blow to Rupp's career came about, when the German Physical Society's decided not to allow any citations of Rupp's work. This seems to have had very severe consequences, as today it is almost impossible to find any quotations - or even mentioning of Rupp in general, let alone his fraud - in any historical studies of either quantum theory or of Einstein.Despite the unquestionable fraud by Rupp, his experiments and collaboration with Einstein might have had a positive influence on the further progression to quantum mechanics. The two present papers became of seminal importance in the discussions between Bohr and Heisenberg, which eventually in 1927 resulted in Heisenberg publishing his landmark thesis on the uncertainty principle. When Max Born received the Nobel Prize in physics he stated that: ""An idea of Einstein gave me the lead [From the present paper]. He had tried to make the duality of particles-light quanta or photons-and waves comprehensible by interpreting the square of the optical wave amplitudes as probability density for the occurrence of photons.""Boni 160" Weil 153.‎

‎APPENDIX FOR THE SECOND EDITION [of The Meaning of Relativity] + APPENDIX II. GENERALIZED THEORY OF GRAVITATION. - [ORIGINAL PROOF-COPY]‎

‎[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).‎

‎First edition. In this paper ""Contributions to quantum theory"" two considerations are given which are interrelated by a common goal, inasmuch as it is attempted to derive two of the most importent achievementss of quantum theory, viz. Planck's radiation law and Nernst's third law of thermodynamics, in a new manner. The proofs do not involve Boltzmann's equation and are thus based enterely on macroscopic thermodynamics. They do introduce, however, the quantum hupothesis. (Einstein points out that the alleged 'proofs' which try to derive the theorem of Nernst from the mere fact that the heat capacity of all substances goes to zero at absolute zero temterature, are not genuine).
