Entwurf einer verallgemeinerten Relativit?tstheorie und einer Theorie der Gravitation. [Outline of a Generalized Theory of Relativity and of a Theory of Gravitation](175 views)
Description: FIRST EDITION, OFFPRINT, of Einstein’s breakthrough work on general relativity: the famous “Entwurf” paper. From the library of physicist Walther Gerlach. ?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. Provenance: Walther Gerlach's copy, with his stamp on the front cover. Gerlach was a major figure in 20th-century physics, known primarily for his role in the Stern-Gerlach experiment, discovering spin quantization in a magnetic field. Offprint from Zeitschrift f?r Mathematik und Physik, volume 62. Leipzig and Berlin: Teubner, 1913. Octavo, original wrappers; custom box. A hint of toning around edges. An outstanding copy, very rare in such good condition.
