Einstein, Albert (1879-1955).
Zur Affinen Feldtheorie. {Relativity]
Berlin: Sitzungsberichte der Preussischen Akademie der Wissenschaften, XVIII, Berlin 1923 - Einstein, Albert (1879-1955). Zur affinen Feldtheorie. Offprint from Sitzungsberichten der Preussischen Akademie der Wissenschaften 1923. XVIII. 8vo.,4, [137-140] First edition. Orange wrappers. A fine fresh copy in the rare off-print form marked with an asterisk by Weil, denoting a major paper ("Sonderabdruck") & deemed of sufficient interest that a translation was published in Nature Magazine. "Einstein's attempts to formulate a unified field theory [the theoretical framework to account for the fundamental forces of nature.] stemmed from his dissatisfaction with the general relativity theory, which did not adequately incorporate the electromagnetic field into the geometry of space-time". Einstein's first investigation of Weyl's ideas, published in the present paper which Weyl had begun working on in 1918. Weyl was investigating the possibility of constructing a unified field theory preserving the dimensionality of space-time while formally altering its geometry, making it a special case of the class known as affine geometries*. However Einstein later rejected Weyl's theory. "Weil No. 132*; Schilpp--Shields No. 171; Alicke No.113; Norman Library 698; Boni 141. *Affine Geometry is not concerned with the notions of circle, angle and distance. It's a known dictum that in Affine Geometry all triangles are the same. In this context, the word affine was first used by Euler (affinis). In modern parlance, Affine Geometry is a study of properties of geometric objects that remain invariant un … [Click Below for Full Description]
