...Sumner's clientele is rather unique, in that it is composed of three distinct groups "the so-called common people, the professors and the Brattle Street element, and the undergraduates, not to mention the youthful audience at Saturday morning's Mickey Mouse Matinees...
...young daughter and her brilliant young son-in-law were showing themselves to be able and devoted scientists. In the Curie Laboratory of Paris' Institut du Radium Irène Curie-Joliot and Jean Frederic Joliot were shooting alpha particles (nuclei of helium atoms) at the lightweight element beryllium. Strange rays hopped out of the beryllium. Fed into paraffin, the rays knocked out protons (hydrogen nuclei) at dizzy speeds of one-tenth the velocity of light. What were the strange rays...
...Paris last year the Curie-Joliots were firing alpha particles at another light element-boron. Neutrons leaped out. But after the bombardment stopped, the boron continued to emit positive electrons as though the attack had stirred it into a sort of radioactivity. This unlooked-for discovery made necessary a new phrase: artificial radioactivity (TIME...
...There are some things only a man can do!" cried this Apotheosis of the Little Man. "I exalt women as the stablest element in our Reich because woman judges with her heart, not with her head! . . . I would not be here now had not women supported me from the very beginning. . . .We deny the Liberal-Jew-Bolshevik theory of 'women's equality' because it dishonors them! . . . A woman, if she understands her mission rightly, will say to a man. 'You preserve our people from danger and I shall give you children.' " (Cries of "Ja! Ja! Heil Hitler...
Heavy Neon. Isotopes are forms of the same element having different atomic weights. Most famed isotope is "heavy hydrogen" for which Columbia's Harold Clayton Urey won last year's Nobel Prize in Chemistry. Dr. Gustav Hertz of Berlin's Siemens Engineering Works told how he extracted 98% pure ''heavy neon" (atomic weight 22) from ordinary neon (atomic weight 20). The separation, accomplished with the help of mercury in a long series of connected flasks, was so ingenious that Dr. Hertz's description of it was heartily clapped, and when he had finished...
