Experimental Relativity Hits the Big Time Available to Purchase

The turnout for the third “Cambridge” Conference on Relativity was so large that one speaker complained: “I was told that the meeting would just be a few guys standing around a blackboard. Now I see that even the physics press is here.” At the meeting, held at the Goddard Institute for Space Studies on 8 June, experimenters discussed measurements of gravity waves, bending of electromagnetic waves by the sun, relativistic time delays and the dragging of an inertial frame by the earth.
