EINSTEIN, Albert (1879-1955) and Walter MAYER (1887-1948)
‘Einheitliche Theorie von Gravitation und Elektrizitat.’ Offprint from: Sitzungsberichte der Preussischen Akademie der Wissenschaften, physikalisch-mathematischen Klasse XXV, pp. [1]-19. Berlin: Akademie der Wissenschaften, 1931.
Author’s offprint of Einstein’s description of five dimensions. In 1921, Kaluza proposed an alternative unified field theory in direct opposition to Weyl, by supposing the dimensionality of space-time be enlarged and formal geometry preserved. In this paper, Einstein, and his assistant Mayer, reject Weyl and Eddington’s theories (see previous lot), reformulating Kaluza’s theory by constructing a five-dimensional vector space at each point of four-dimensional space-time, projectively mapping from the 5-D vector spaces to the 4-D tangent spaces (see lot 43). Though the theory succeeded in deriving the field equations for gravity and electromagnetism from this approach, it could not account for the structure of matter (the existence of charged particles and currents being incompatible with the field equations). A short second part, in which Einstein developed his thoughts on this matter, was published in the following year, and is not included in this lot. This author’s offprint can be distinguished from the normal ‘trade’ edition by the statement ‘Uberreicht vom Verfasser’ on the wrapper. Very rare as author’s offprint. Norman 701; Weil *182 (identifying this as one of Einstein's major papers).
Quarto (255 x 184mm). 10 ll., paginated [1]-19. Original printed orange wrappers (a fine copy).
