Much has already been learned about the properties of matter at temperatures close to the utmost cold. Lead, for example, shows superconductivity, which means that an electric current passing through it keeps on flowing after the circuit is broken. It is unlikely that another fraction of a degree will bring any startling revelation. But the remote chance that it might keeps the low- temperature men pressing indefatigably closer & closer to the inaccessible bottom...
Died. Mrs. Corra Harris, 65, author (A Circuit Rider's Wife, My Book and Heart); of a heart attack; in Atlanta. Crisp, optimistic Mrs. Harris taught a course in "Evil" at Rollins College in 1930 (TIME...
There are three main oscillating circuits in this instrument produced by ordinary vacuum tube methods. Two of the circuits, one superimposed on the other, cause oscillations of audio-frequency which can be heard through a loudspeaker. The remaining oscillatory circuit controls the volume...
...show in London during the Physical Society's annual exhibition at the Imperial College of Science & Technology last month was a delicate device of highly specialized application. Essentially it consists of two thermometers hooked into an electric circuit. In practice one thermometer is buried just under the surface of the soil, the other supported in the air just above. The upper thermometer gives the air temperature, and since the buried one cannot be seen, a dial records the temperature differential between the two. From that the warmth of the ground can be computed...
...make what the philosophers call value-judgments. Personal History is the warm, semi-rueful story of how this sea-change came about as Sheean wandered from Chicago to New York, to Paris, to Persia, to China, to the Holy Land, to dinner parties in London and around the lecture circuit...
