First offprint in the original wrappers, of Einstein's paper on the subject of intermolecular forces. - Edition: In this work Einstein calculated the rate of chemical reactions in a gas by means of observations on the propagation of sound (see Mason, »Physical Acoustics«, p. 13), an important contribution to modern acoustics. - Condition: Very fine indeed. - Rarity: According to Weil early offprints of Einstein’s papers may also be qualified as original and also highly collectable editions, however they were printed in a certain, but still small print run for commercial use (mainly to sell them to fellow natural scientists): „No doubt, the first appearance in a periodical is the „original edition“, but I have to leave it open for collectors, librarians and others to decide whether these offprints in wrappers, mostly with a printed title on them (especially in the »Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften«) are also „original editions“. These offprints are printed from the same setting as the text, but often with new pagination.“ (p. 4). Additionally to offprints like the present, some copies bearing the imprint „Überreicht vom Verfasser“ [Presented by the Author]. ABPC (1973ff.) and APO (1988ff.) record only 1 copy of this edition at auction (2011). - Reference: Boni-Russ-L. 119; Collected Papers, vol. 7, 39; Schilpp-Shields 135; Weil 110.
First offprint in the original wrappers, of Einstein's important follow-up paper on the field equations in his General Theory of Relativity. - Contents: In present paper Einstein suggests a modification of his field equations to allow for stable elementary particles. According to Pais this text "may be considered Einstein's first attempt at a unified field theory"” (Pais, Subtle is the Lord, p. 287). - Condition: Cover at margins minimally dusty, otherwise very fine indeed, probably unread. - Rarity: According to Weil early offprints of Einstein’s papers may also be qualified as original and also highly collectable editions, however they were printed in a certain, but still small print run for commercial use (mainly to sell them to fellow natural scientists): „No doubt, the first appearance in a periodical is the „original edition“, but I have to leave it open for collectors, librarians and others to decide whether these offprints in wrappers, mostly with a printed title on them (especially in the »Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften«) are also „original editions“.

First offprint in the original wrappers, of Einstein's paper on photons. - Condition: Front cover with some very small spots, otherwise very fine. - Rarity: ABPC (1973ff.) and APO (1988ff.) record only 2 copies of this edition at auction (2009, 1994). - Reference: Schilpp-Shields 162; Weil 120.
First offprint in the original wrappers, of Einstein's paper on the important findings of German mathematician and physicist Theodor Kaluza about gravitation and electricity. - Content: Kaluza "attempted to unify Einstein's theory of gravity with Maxwell's theory of light by mixing them in a fifth dimension". Together with the Swedish theoretical physicist Oskar Klein Kaluza produced the „Kaluza-Klein field equations" (Calaprice, Einstein Almanac, 135). Their insights, however, were "neglected for many years as attention was directed towards quantum mechanics. [Their] idea that fundamental forces can be explained by additional dimensions did not re-emerge until string theory was developed" (Wikipedia). - Condition: Mint. - Reference: Boni-Russ-L. 170; Schilpp-Shields 212; Weil 156.
First offprint in the original wrappers, of this first attempt of Einstein to formulate a unified field theory. - Content: In this important paper Einstein gives his first investigation of "Affine geometries" and introduces the notion of "Distant parallelism", thus for the first time attempting to formulate a unified field theory based on the research of the German mathematician, theoretical physicist and philosopher Hermann Weyl. - Condition: Mint. - Reference: Alicke 113; Norman Library 698; Schilpp-Shields 175; Weil *132.
First offprint, in the original wrappers. - Content: In this paper Einstein accepted that his introduction of the 'cosmological constant' in 1917, in order to allow for the possibility of a static universe, may have been a mistake. - Condition: Very fine. - Rarity: ABPC (1973ff.) and APO (1988ff.) record 4 copies of this edition at auction (2012 (2x), 2011, 1994). - Reference: Boni-Russ-L. 140; Schilpp-Shields 174; Weill 131.
First offprint in the original wrappers, of this important paper by Einstein formulating groundbreaking developments towards a unified field theory. - Content: »On The Unified Field Theory« is one of Einstein's last scientific core works. According to Weil "This paper represents a new development which was immediate news. A translation by L.L.Whyte appeared in the (London) Times of Feb. 4, 1929. It was quoted in full in "Observatory", vol. 52, under the title "New Field Theory" pp.82-87 and (1930) pp.11-118." In 1928 Einstein embarked on a new approach to a unified field theory, involving what he called „distant parallelism“. By early 1929 he had solved the main problems involved in writing down field equations for his unified field theory. On the day of offical publication of the third of a formidably technical series of 9 articles on the theory, excited headlines appeared in newspapers around the world. - cf. Parkinson, Breakthroughs, p.279. - Condition, State: Mint, uncut, thus unread. - The list of academy offprints on the rear side of the cover states present offprint not in last place. All offprints listed later were printed in 1929 though. The typeset of all pages is identical to other authentified offprints of this papers. This indicates that our copy is indeed a first offprint, but presumably with a later cover. - Reference: Alicke 141; Boni-Russ-L. 183; Norman Collection I, 700; Printing and the Mind of Man 416 („Principal Work“); Schilpp-Shields 226; Weil *165.
First offprints in the original wrappers, of two of Einstein's papers about the interrelations of the General Theory of Relativity and the Law of Motion, the 2nd paper conducted with his assistant Jakob Grommer. - Condition: Mint. - Reference: Boni-Russ-L. 171; Schilpp-Shields 212; Weil 155 and 160.
First offprints in the original wrappers and new pagination, of this important two-part paper by Einstein formulating new developments towards Unified Field Theories. - Content: Einstein made several attempts at a five-dimensional unified field theory, including this two-part collaboration with Austrian mathematician Walther Mayer (nicknamed „Einstein's calculator“), "in which a new unified field theory was proposed, one based on a four-dimensional space-time continuum with a five-dimensional tangent space attached at each point" (Pais, Subtle is the Lord, p. 492). - Condition: Very well preserved. - Reference: Boni-Russ-L. 207; Printing and the Mind of Man 416 („Principal Work“); Schilpp-Shields 251 and 261; Weil *182 and *185 (quotes the paginations of the first separate printings, p. 541-557 and 130-137).
First offprint in the original wrappers and new pagination, of this rare seminal paper, at the same time Einstein's last publication before having to leave Nazi-Germany. - Content: Present paper ist the last work by Einstein, co-authored once again by Walther Mayer, that was published in Weimar Germany (Weil no. 187 was printed before). The offprint was distributed by the Prussian exactly a week before the Nazis came to power on January 30th 1933. Einstein, and also Mayer, would have to flee Germany due to their Jewish origins only a few months later. - Einstein's work on semivectors "was stimulated by Ehrenfest's insistence on a better understanding of the relation between single-valued and double-valued representations of the Lorentz group . . . [Einstein and Mayer] went on to relate semivectors to the Dirac equation and to generalize the formalism to general relativity" (Pais, Subtle is the Lord, pp. 451-452). - Condition: Mint. - Reference: Alicke 152; Boni-Russ-L. 217; Schilpp-Shields 250; Weil 186 (quotes the pagination of the first separate printing, p. 522-550).
First offprint in the original wrappers and new pagination, of this late paper by Einstein about field equations in a Riemannian Space. - Content: This work was written in collaboration with his assistant, the Austrian mathematician Walther Mayer (nicknamed „Einstein's calculator“). In 1928 Einstein already had made use of the Elliptic geometry of German mathematician Bernhard Riemann for his calculations. - Condition: Mint. - Reference: Alicke 149; Schilpp-Shields 250; Weil 180 (quotes the pagination of the first separate printing, p. 257-265).
