‎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). PMM: 408. Horblit 26 c.

‎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

[Entire volume: VIII, 1000 pp. + 4 plates].‎

‎First edition of the first explicit statement of Einstein's landmark 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.
