...specially designed deep-sea diving tank, doubtless on the order of Inventor Hartman's "diving bell" which has penetrated thousands of feet deeper than any live man ever went in the ocean and came back to tell about it (TIME, Aug. 24, 1925). The tank is fitted with oxygen pumps and other breathing apparatus and a glass window capable of withstanding many tons of pressure to the square inch. For illumination he planned to depend entirely, at first, upon the abysmal brilliance of deep sea creatures...
Admitted that scholasticism is inevitably associated with a gloomy atmosphere, still there is no adequate reason why students should be deprived of sufficient oxygen to maintain their health and comfort. To be cruclly specific--the air in certain parts of Widener Library, notably the upper and lower reading rooms, is a thing of wonder: it gives rise to thoughts concerning medieval dungeons, and suspicions to the effect that ventilating systems sometimes do everything but ventilate. With all the clever conceits of modern architecture one might reasonably suppose that a pure environment could be provided for those whose...
Wood Alcohol. Ages ago coal was, of course, living wood, and now, like wood, it is being converted into methyl (wood) alcohol. General Georges Patart of France makes this alcohol by heating soft coal until carbon monoxide and hydrogen result. To these gases he adds oxygen to form an organic product. Then, with this synthetic compound on hand he can create formaldehyde (essential for the synthetic resins like Bakelite) or the more complicated alcohols (as isobutyl and amyl, useful in making varnishes...
...characteristics a Martian being would have to have to live: a hide thick enough to Stand temperature ranging 150 Fahrenheit between noon and midnight; ability to migrate from 60° North Latitude to 60° South with the seasons; lungs capable of using atmosphere as poor in oxygen as that encountered by terrestrial aviators on their highest flights and as dry as the Sahara...
...upon the aluminum disc of earlier experiments. It was a sheet of nickel 1/2000 of an inch thin and three inches in diameter, supported against the 100-pound suction of the vacuum tube by skeleton struts of molybdenum. The molecular structure of nickel is such that molecules of air (oxygen, nitrogen) cannot pass through it, though it offers a minimum of resistance to those billionth parts of molecules, electrons...
