Theoretical physics last week again proved that it has substance. The lightest element, hydrogen, has an atomic weight of 1.0078. The helium atom, next lightest in the table of elements, weighs 4.002. Are there no substances in between, with atomic weights of approximately...
...discrepancy between the spectrographic and chemical calculations of the weight of the hydrogen atom suggested that there must be a rare isotope of hydrogen mixed with the abundant common hydrogen found in water and sugar. Such an isotope would behave chemically like hydrogen, but weigh two, perhaps three times as much. Professor Raymond Thayer Birge of the University of California and Professor Donald Howard Menzel of Harvard calculated that one part of heavy hydrogen should appear in 4,500 parts of ordinary hydrogen...
Production of "heavy water," a new substance in which the hydrogen atom has a mass of two instead of one, is new possible due to recent experimental research by Arthur A. Frost, Harvard Fellow in Chemistry, and others at Princeton, New Jersey...
...Soviet Army's stratostat U.S.S.R., largest balloon ever made, was finally ready last week in Moscow for a flight to the stratosphere. A morning fog had weighted the turnip-shaped gasbag with a heavy load of moisture; a drop in temperature had caused the hydrogen to contract. Nevertheless the crew of three aeronauts and two 'chute jumpers sealed themselves in the spherical gondola for a takeoff. W^ith a dramatic flourish Air Commander Garankidze waved the ground crew to cast off. The huge bag rose groggily about 10 ft. It wobbled sideways across the airdrome...
...humans, worms, oysters, plant molds, bacteria and algae. Declared they: "It is probably safe to say that it is more widely distributed in Nature than any known physiologically potent substance." Data so far accumulated indicates that pantothenic acid's molecule is composed of long chains of carbon, hydrogen and oxygen, that it contains no sulphur or nitrogen. The stuff is potent. A speck of Professor Williams' latest pantothenic acid, extracted from liver, speeds the growth of yeast in 250 gal. of liquid...
