‎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).‎

Besides, other generalizations were subsequently presented. The (non)-existence of such solutions in classical unified field theory was undoubtedly an important criterion leading Einstein's investigations.""(Galvagno and Giribet).""In his search for a unified field theory that could undercut quantum mechanics, Einstein considered five-dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated, and in the x5-independent theory Einstein, together with Pauli, argued it would be impossible to find these structures.""

‎First issue of the first edition in book form, being, not an offprint of the""Annalen der Physik"" journal issue as often stated, but a separate edition of the paper, completely re-set and with significant changes and additions, including for the first time in print the ""Einleitung"" and the ""Inhalt"".The first issue is distinguished from the later reprints by the printing of ""Sonderdruck aus dem ""Annalen der Physik"" Band 49, 1916"", and ""Druck von Metzger & Wittig in Leipzig. 314"" to the verso of the title-page and ""Metzger & Wittig, Leipzig"" to the foot of the back wrapper. Furthermore, ""This separate edition is printed on good, strong paper, the wrappers are of strong material too, and it is described now as 'the original edition' of this classic paper"" (Weil). Einstein's seminal ""General Theory of Relativity"" has had an immense impact on all science, philosophy, and man's view of the world in general. Few other books of the 20th century can be said to have so basically altered the way that we view the world and our place in it. Determining space and time as being interwoven into a single continuum known as ""space-time"" and determining that there is no absolute space-time coordinate system - i.e. that there are no absolute positions in time and pace - established the fact that events that occur at the same time for one observer could occur at different times for another, i.e. all positions in space and time are relative. This general theory of relativity, here presented in its full exposition for the first time, in book form, is now a basic foundation for scientific thought.""The theory of relativity has transformed astrophysics, and indeed the whole scientific outlook."" (PMM).""Whereas Special Relativity had brought under one set of laws the electromagnetic world of Maxwell and Newtonian mechanics as far as they applied to bodies in uniform relative motion, The General Theory did the same thing for bodies with the accelerated relative motion epitomized in the acceleration of gravity. But first it had been necessary for Einstein to develop the true nature of gravity from his principle of equivalence...Basically, he proposed that gravity was a function of matter itself and that its effects were transmitted between contiguous portions of space-time... Where matter exists, so does energy"" the greater the mass of matter involved, the greater the effect of the energy which can be transmitted. In addition, gravity affected light... exactly as it affected material particles. Thus the universe which Newton had seen, and for which he had constructed his apparently impeccable mechanical laws, was not the real universe... Einstein's paper gave not only a correct picture of the universe but also a fresh set of mechanical laws by which its details could be described"" (R.W. Clark). ""This paper was the first comprehensive overview of the final version of Einstein's general theory of relativity after several expositions of preliminary versions and latest revisions of the theory in November 1915. It includes a self-contained exposition of the elements of the tensor calculus that are needed for the theory. (T. Sauer in Landmark Writings in Western Mathematics).

‎Offprint of all four papers and first edition of the final essay, constituting Einstein's attempt toward creating a unified field theory: ""a new theory of space with a view to unification of all forms of activity that fall within the sphere of physics, giving them a common explanation"" (PMM416). The task of unifying nuclear, electromagnetic, and gravitational force is nowadays by many considered the holy grail of theoretical physics.Maxwell was the first to develop such a theory when he described the forces of electricity and magnetism as the single force electromagnetism. After Einstein had completed his general theory of relativity (a field theory for gravitation), he turned his attention towards generalizing his theory even further to include Maxwell's theory. Even though Einstein never succeeded in completing this task, in the way that he finished his earlier theories, he pioneered and explored many areas of this subject. ""It had been repeatedly observed that Einstein's general theory of relativity necessitated a pluralistic explanation of the universe. In 1925 he announced that he had resolved this difficulty but the announcement was premature. In 1928 he attacked the problem once more, only to find that Riemann's conception of space, on which the general theory was based, would not permit of a common explanation of electromagnetic and gravitational phenomena. In a series of papers [the present] devoted to the development of 'A Uniform Theory of Gravitation and Electricity' he outlined a new theory of space with a view to unification of all forms of activity that fall within the sphere of physics, giving them a common explanation. All that would then remain to complete a scientific unison is the correlation of the organic and inorganic"".PMM 416Barchas 586‎
