...atmosphere of hydrogen. This was magnified and projected in color on a frosted glass screen. The engineers saw the images of the electrodes three inches apart, with the broad, vivid flow of the arc two inches wide. Then Dr. Suits produced an arc in an atmosphere of nitrogen. The arc band was pale, thin. But when he stepped up the nitrogen pressure to 1,200 Ib. per sq. in., the arc thickened and brightened until it was indistinguishable from that produced in hydrogen...
...that the outpouring of injurious ultraviolet radiation may be so strong that human beings would have to carry umbrellas coated with lead before venturing under the glare of "Nova Cassiopeiae." Other highlights of the astronomers' convention: Nos- 60, 61, 62. In the sun hydrogen, helium, calcium, sodium, carbon, nitrogen, and many another terrestrial element have been identified by comparing the solar spectrum with very clear spectra of substances photographed in the laboratory...
...industrial chemist, Friedrich Bergius was born in what is now the Polish Corridor, became assistant to Fritz Haber who won a Nobel Prize for the fixation of atmospheric nitrogen. Bergius himself was awarded the Nobel Prize for Chemistry in 1931, now lives at Heidel- berg in close touch with its university...
Synthetic Atmospheres. Without oxygen animals smother; in pure oxygen they die also because of irritation and congestion in the lungs. Yet it must not be assumed that the best possible mixture for sustaining life is the natural atmospheric mixture of about 79% nitrogen, 20% oxygen and 1% other gases. After twelve years of smothering rats, monkeys and guinea pigs in various artificial atmospheres ranging from pure helium to nitrous oxide, Dr. John Willard Hershey of McPherson College reported that a mixture of 75% argon and 25% oxygen enabled the animals to get along as well as usual, that...
...Gotebo, Okla. 29 years ago, got his Ph. D. at 23 from Massachusetts Institute of Technology, and is now an assistant professor at Cornell. Of little interest to laymen, Dr. Kirkwood's work on the dielectric properties of gases under pressure and on polarization phenomena in methane, nitrogen and hydrogen provided invaluable working tools for chemists. Said the award committee: "He succeeded in instances where older and more experienced men of proved ability have failed to arrive at definite results...
