MAJORANA, Q. - PROVING THAT THE SPEED OF LIGHT IS INDEPENDENT OF ITS SOURCE.

Démonstration experimentale de la constance de vitesse de la lumiére réfléchie par un miroir en mouvement.

(Paris, Gauthier-Villars), 1917. 4to. No wrappers. In: "Comptes Rendus hebdomadaires des Séances de L'Academie des Sciences", tome 165, No 14. Pp. (417-) 448. (Entire issue offered). Majorana's paper: pp. 424-428. A stamp in upper right corner of the first page.

First apperance of Majorana's paper which was the first experimentally to prove the speed of light as set forth by Einstein in his special relativity theory. Majorana was critical to Einstein's relativity, and he therefore tried to prove experimentally that the postulate of the speed of light was wrong. His experiments turned out otherwise, and he hereby proved Einstein's postulate that the speed of light was independent of the velocxity of its source.
