Towards the latter part of the war, as Major Conant, he supervised more than 100 chemists in a secret experiment on poison vapor, during which he and his staff were closely guarded and virtually held prisoner...
With whimsical and bogus tenderness, U. S. newspapers last week kissed their old favorite, the Man from Mars, goodby. Reason: Walter Sydney Adams, astute director of Mt. Wilson Observatory in California, said he had observed the Martian atmosphere for water-vapor content, found none or almost none-in any case (allowing for instrumental error) not more than 5% of the moisture in earth's air. In such dryness it seemed most unlikely that active animals could exist. In making his observations, Dr. Adams used "the most delicate spectroscope yet known...
...spectroscope splits light into patterns in which the "signatures" of various elements and compounds can be identified. Light from Mars comes through the earth's air blanket, which contains water vapor, so Dr. Adams had to separate the terrestrial vapor pattern from the Martian (if any). This he did with the help of a phenomenon called the Doppler effect: when a source of light approaches earth, its spectrum lines are shifted to the right, and when it is receding they are shifted to the left. At times when Mars is fast approaching or retreating, the Doppler effect should pull...
...quart from $50 to $5, the time from 24 hours to two hours or less. In the neighborhood of absolute zero, ordinary lubricants freeze hard as iron and Kapitza's problem was to find a lubricant for his compressor. He solved the problem by allowing a little helium vapor to squeeze through the piston clearance, so that the helium itself did the lubricating...
...loneliness. Few had sought and none had won a third election to the Presidency. Knowing U. S. history as a boy knows batting averages, Franklin Roosevelt knew that he had left the shelter of precedent, had pushed off on a course without chart or landmark. Through the vapor that is the future he could steer only by the North Star of his own purpose...
