FIRST EDITION COMMERCIAL OFFPRINT ISSUE of Einstein's breakthrough work on general relativity: the famous "Entwurf" paper. "In this book Einstein and Grossman investigated curved space and curved time as they relate to a theory of gravity. They presented virtually all the elements of the general theory of relativity with the exception of one striking omission: gravitational field equations that were not generally covariant. Einstein soon reconciled himself to this lack of general covariance through the 'hole argument' which sought to establish that generally covariant gravitational field equations would be physically uninteresting. Einstein did not adopt the gravitational field equations until late in 1915 in his final formulations of the general theory. Here Einstein contributed the physics and Grossman the mathematics" Calaprice The Einstein Almanac 40. Weil 59a. Offprint from Zeitschrift für Mathematik und Physik volume 62.

EXTREMELY RARE AUTHOR'S OFFPRINT "Überreicht von den Verfassern" IN ORIGINAL WRAPPERS OF THE FIRST PRINTING OF EINSTEIN AND GROSSMANN'S FURTHER DEVELOPMENT OF THE CRITICAL "ENTWURF" THEORY OF 1913. "Einstein returned from Prague to Zurich in the summer of 1912. He had by then already formulated the fundamental physical principles of the general relativity theory of gravitation and was now searching for their mathematical structure. At the E.T.H. the Swiss Federal Institute of Technology in Zurich where he now returned as professor of theoretical physics Einstein met again his old fiend and former fellow student Marcel Grossmann who was now a professor of mathematics and his colleague. With Grossmann and under his guidance Einstein studied the mathematical literature especially the theory of invariants and the absolute differential calculus of Chirstoffel Ricci Levi-Civita and others. Einstein developed the mathematical structure of his theory jointly with Grossmann and in his celebrated paper on the general theory of relativity in 1916 he acknowledged the help which his friend had given him. It was Grossmann's help which had Einstein said 'spared me not only the study of the relevant mathematical literature but who Grossmann also assisted me in searching for the field equations of gravitation.' This study of mathematical literature and the search for the proper mathematical tools led to several joint papers with Grossmann during Einstein's all too brief stay in Zurich. These papers contained the first attempts toward a generalized theory of relativity using new mathematical tools and gave full expression to Einstein's earlier physical insights" Jagdish The Golden Age of Theoretical Physics. The first of Einstein's papers to present his collaborative work with Grossmann the famous "Entwurf" paper appeared in the summer of 1913; the present paper based on a lecture given on September 9 1913 to the 96th annual meeting of the Swiss Society for Natural Sciences in Frauenfeld provides further details on the new generalized theory of relativity. The published paper contains more mathematics than in the given lecture. Weil 57.

19191857Berlin: Königlich Akademie der Wissenschaften 1919. First Edition. Fine. FIRST EDITION IN ORIGINAL WRAPPERS of one of Einstein's major papers on the modification of general relativity and the beginning of his unified field theory. "As so often the case in relativity the story of quantum gravity begins with Einstein himself. Soon after the final formulation of general relativity he pointed out the need for a quantum modification of the theory. In "Do Gravitational Fields Play an Essential Role in the Structure of the Elementary Particles of Matter" he began to speculate whether gravitation plays a role in the atomistic structure of matter: There are reasons for thinking that the elementary formations which go to make up the atom are held together by gravitational forces. The above reflections show the possibility of a theoretical construction of matter out of the gravitational field and the electromagnetic field alone. "In order to construct such a model of an 'elementary particle' Einstein shows that it is necessary to modify the original gravitational field equations. The major interest of this paper is that his attention now shifted from possible quantum modifications of general relativity to the search for a unified theory of the electromagnetic and gravitational fields on the basis of which he hoped to explain the structure of matter. Quantum effects are to be derived from such a theory rather than postulated ad hoc. Einstein remained committed to this approach for the rest of his life: the search for a 'natural' mathematical extension of the general theory in the hope that such a theory would somehow explain the quantization of matter and energy" Iyer and Bhawal Black Holes Gravitational Radiation and the Universe.

"In his paper of 1922 Friedmann offered a complete analysis of the solutions of Einstein's cosmological field equations that went beyond the earlier solutions of Einstein and de Sitter as it also included nonstatic solutions. Friedmann did so clearly and explicitly: "The purpose of this note" he wrote "is firstly to show that the cylindrical Einsteinand spherical de Sitter worlds are special cases of more general assumptions and secondly to demonstrate the possibility of a world in which the curvature of space is independent of the three spatial coordinates but does on time".Ibid.In 'Über die Krümmung des Raumes' Friedman derived the non-stationary solutions to Einstein's field equations.

"Friedmann made a valuable contribution to Einstein's general theory of relativity. As always his interest was not limited simply to familiarizing himself with this new field of science but led to his own remarkable investigations. Friedmann's work on the theory of relativity dealt with one of its most difficult questions the cosmological problem. In his paper "Über die Krümmung des Raumes" 1922 he outlined the fundamental ideas of his cosmology: the supposition concerning the homogeneity of the distribution of matter in space and the consequent homogence of "world" time for which at any moment in time the metrics of space will be identical at all points and in all directions. This theory is especially important because it leads to a sufficiently correct explanation of the fundamental phenomenon known as the "red shift." This solution of the Einstein field equations obtained from the above propositions is the model for any homogeneous and isotropic cosmological theory. It is interesting to note that Einstein thought that the cosmological solution to the equations of a field had to be static and had to lead to a closed model of the universe. Friedmann discarded both conditions and arrived at an independent solution. Einstein welcomed Friedmann's results because they showed the dispensability of the ad hoc cosmological term Einstein had been forced to introduce into the basic field equation of general relativity".

Entire volume: VIII 1000 pp. 4 plates. <br/><br/><em>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.

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.
