Abstract

AT a crowded annual meeting on January 4, Prof. A. S. Eddington gave an account of relativity. Those who wish to inform themselves on this subject will naturally go to Prof. Eddington's attractive book, “Space, Time, and Gravitation.” No experiments to determine the motion or whereabouts of the aether had ever led to any but a negative result, as if one solving an equation should end up with the disappointing result 0 = 0 The view had therefore been put forward that there were certain compensating influences concealing the motion of the aether from detection. But Einstein had dared to take up the attitude of Betsey Prig in the matter of Mrs. Harris, “I don't believe there's no sich a person !” The party of Mrs. Harris, however, protested against being called upon actually to produce her.
