L'éther et la théorie de la relativité
1921009631Paris: Gauthier-Villars 1921 8vo 22.5 cm 16 pp. Uncut in printed wrappers wrappers slightly sunned; ownership entry on the title page. French translation by Maurice Solovine of Einstein's well-known 1920 lecture on the concept of the ether delivered at the University of Leiden. In this brief but influential text Einstein revisits the notion of the ether in light of the general theory of relativity arguing that while the classical mechanical ether must be abandoned the relativistic description of space-time still allows one to speak of a form of 'ether' understood as the physical properties of space itself. A concise and important exposition of Einstein's evolving views on the foundations of relativity.Boni-Russ-Laurence 115.B. Gauthier-Villars paperback
