...short visit here, he was also the guest of honor at an informal dinner given by Theodore Lyman '97, Hollis professor of Mathematics and Natural Philosophy, at the Faculty Club. In his speech, Professor Piccard told the story of his two ascents. "The balloon was only partially filled with hydrogen, so that, as it ascended, it slowly assumed a spherical shape. We were forced to do away with netting, owing to the dangers from the pleats of the deflated balloon. Instead, the gondola was swung from a belt, encircling the lower portion of the gas-filled balloon...
...best paper presented at the meeting went to Dr. Henry Eyring, 32, research associate at Princeton, for smart use of Nobel Laureate Max Planck's Quantum Mechanics to explain how the elements hold together in chemical combinations. By mathematics he has shown how to make light hydrogen atoms spin clockwise or counterclockwise at will, how to introduce bromine into organic compounds most easily. By mathematics he has proved that pure fluorine is the least active of the halogen group of elements (fluorine, chlorine, bromine, iodine), a fact which controverts accepted chemistry...
...John Jacob Abel, 75, assumed the A. A. A. S. presidency, succeeding Columbia's Anthropologist Franz Boas, 74. For 1934 president the Association chose Princeton's Astronomer Henry Norris Russell, 55, after he had presented his interpretation of starlight. The light might be the effect of 1) hydrogen and the lighter elements synthesizing into heavier elements, or 2) heavy star material burning to nothing. Professor Russell prefers the synthesis theory, for burning "would not happen except at temperatures of many billions of degrees," whereas "heat should be produced [by atomic synthesis] fast enough to keep the stars shining...
...great importance of radiogens in Dr. Crile's mind is that, if they really exist, they may explain how plants add oxygen & hydrogen to carbon dioxide to make sugar, how animals add oxygen to sugar to form carbon dioxide-chemical reactions which require access of considerable energy...
...Langmuir's investigation along this line led him to utilize hydrogen for welding metals together. When hydrogen is squirted through a tungsten arc light, hydrogen molecules explode into hydrogen atoms. The hot stream of atomic hydrogen can weld pieces of steel together and simultaneously drive away the oxygen and nitrogen which weaken ordinary steel welds...
