...vibration of traffic in Manhattan, even at dead of night, is sufficient to disturb so delicate an instrument. The test of Einstein's theory will be made "somewhere in Illinois." Thereafter, Prof. Hartsough will enlarge his scales and attempt to weigh molecules and atoms; and will consider commercial offers from people eager to try his instruments (he has made three) in locating oil and minerals...
This is elementary, but what Science must argue out with Dr. Einstein is whether or. not gravity is an instantaneous thing, operating at infinite speed. He says not. One proposition of Relativity is that the pull of a body's gravity travels at the speed of light-about 180,300 mi. per sec. Specifically therefore, the moon's gravity pull is felt on earth one and a third seconds after the moon has passed its zenith; the sun's gravity, 8 seconds after high noon...
...would be to weigh small objects, observing whether variations in their weight occur exactly as, or shortly after, the sun or moon passes over them. The weight variations are infinitesimal. To detect them would require fabulously sensitive scales. But could ic be done, Science would have a check on Einstein far more clean-cut and conclusive than ether-drift experiments and eclipse observations...
...Typical research accomplished with the aid of Rockefeller Funds: Prof. A. A. Michelson's (University of Chicago) experiment with light rays in a pipe-rectangle to check the Einstein relativity theory (TIME, Aug. 11, 1924); Professor Niels Bohr's (University of Copenhagen) atomic investigations in the infra-red region of the spectrum (TIME, Feb. 4, 1924), for which he last week received the Barnard Gold Medal from Columbia University...
...nomination of Prof. Einstein, Prof. Schultze-Gavernitz of Freiburg University, Baden, was appointed Chief of the Secton of Sciences at the Institute. He thus became the first German to hold a position under the League. A number of other appointments were made...
