15, (1) pp. 8vo. Orig. wrappers. Berlin, (E. S. Mittler for) Julius Springer, 1920. First edition. Einstein discusses the concept of the aether in relation to his theory of relativity. This lecture examines the historical role of the aether in physics and its transformation under relativity. His conclusion is that relativity does not bring back the classical aether but introduces a new understanding of space as an active, structured entity. The text of this speech delivered at Leiden University was also translated into French in 1921. The English translation appeared in Einstein's "Sidelights of Relativity", published at London in 1922. Einstein's manuscript is now kept in the Bibliotheca Bodmeriana, Geneva. - Weil 111; Boni, Russ and Laurence 115; Roller/Goodman I, 354; Seelig 131; Schilpp-Shields 131. SCIENCE: PHYSICS ;
