einheitliche feldtheorie und hamiltonsches prinzip von einstein albert, Gebraucht (7 Ergebnisse)

(27 x 18,5 cm). SS. 123-159. Original-Broschur, unbeschnitten. Erste Ausgabe. - Wohlerhalten. - Weil 166. - Der Band enthält u.a. noch: Vereinfachte Herstellung der Einsteinschen einheitlichen Feldgleichung von T. Levi-Civita. 17 S.

Zustand: Fine. First separate edition. 6 pages in printed wraps. Not exactly an "offprint," since the pages are numbered from 1, and the pamphlet is given its own title page, this is considered the first separate edition of a paper Einstein published in the periodical of the Prussian Academy. It is considered Einstein's initial effort, having established general and special relativity, to find a unified theory uniting gravity and electromagnetism, a problem he struggled with for his remaining life.

S.Ber. Akad. Wiss. Berl., 1928/10. - Berlin, Verlag der Akademie der Wissenschaften, 1929, 8°, 6 S., orig. Broschur. First Edition; the rare off-print from the "Sitzungsberichte". Weil No.166; Schilpp-Shields No. 227; Alicke No. 143.

Berlin, Gruyter & Co., 1929. 4to. Orig. printed orange wrappers. Offprint/Sonderausgabe aus Sitzungsberichten.pp. (1)-6. Fine fresh copy. First edition in the rare Offprint, now called "Sonderausgabe" instead of "Sonderabdruck", having separate printed title and separate pagination. See Weil: 166, where this is not mentioned.The early Offprints from "Sitzungsberichten." are called "Sonderabdruck" up to Weil No.165 (including this). From Weil 166 they are called "Sonderausgabe.". - Before 161 (up to 160) the Offprints do not have separate title and pagination (the pagination follows the numbering in the periodical). From 166 the Offprint has both separate printed title and pagination. - ( So Weil Nos 161-165 is still "Abdruck", but with separate title and pagination). These facts are not mentioned in the bibliographies.Weil No. 166.

Fine collection, three in offprint and one in the original printed wrappers, of the four papers that together constitute Einstein's attempt towards 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 586Weil 147, 162, 165 & 166.
