...which is only .000005 as dense as water. But as red giants contract, they get hotter, as air in a pump gets hotter when it is compressed. The sun appears to be some two billion years old now, and it is hot enough to live on atomic energy, converting hydrogen into radiation...
France, like her ally, is calm and proud." As he concluded, swift Reynaud made one last plea for speed: "Immense values are at stake and time is limited."Calm and proud. Someone has said that though most human bodies are composed of oxygen (65%), carbon (18%), hydrogen (10%), nitrogen (3%), calcium (1.5%), phosphorus (1%), the body of a Frenchman is a simple compound of pepper, garlic, pate de foie gras, common bread and good red wine of the land. The French are pungent people. Little things make them gesticulate wildly and pour maledictions like a flood: a bowl of soup...
...Edward Lawrie Tatum and George Wells Beadle isolated in crystalline form one of two hormones by means of which Drosophila'?, genes control the fly's eye color. At Caltech, Dr. Arie Jan Haagen-Smit analyzed the hormone, found its molecule contained 21 atoms of carbon, 34 of hydrogen, two of nitrogen. 14 of oxygen. If the California scientists can follow up this first success by isolating and identifying the other eye-color hormone, they may cast a sudden brilliant light on how genes control heredity...
Professor Shapley emphasized the importance of the use of rays and radiation in many fields of science, such as the studying through invisible glass of the heretofore invisible storms of hydrogen, iron, and calcium on the too-visible surface of the sun. He told how scientists apply their research to practical work, using their rays in clinics, biological laboratories, agricultural experiment stations, and testing bureaus for textiles, guns, and even fake paintings...
Last year Cornell University's brilliant, Alsatian-born atomic theorist, Professor Hans Albrecht Bethe, trotted out a plausible explanation of how the sun converts hydrogen into radiant energy, and so keeps on shining (TIME, Feb. 27, 1939). At temperatures above 15,000,000° C. (the sun's internal temperature is calculated at 20,000,000° C.), Dr. Bethe found that hydrogen atoms would attack carbon. The carbon would be transmitted into other forms, but after a series of six separate atomic conversions, it would reappear, while hydrogen atoms (of which the sun has enough to last...
