...this industry there is constant need for heating and cooling oil at both high and low temperatures--up to perhaps 1200 degrees Fahrenheit and down to 90 degrees below zero. In order that apparatus may be intelligently designed to do this work it is essential that the engineer have dependable information, so that he is often forced to substitute guesses for accurate knowledge...
This year the problem is to recapture Hawaii from a hypothetical enemy. As the zero hour approached for Admiral Richard Henry Leigh's Blue force to cross a deadline and commence hostilities, the defensive Blacks, surmising that the attack's spearhead would aim at Honolulu's Pearl Harbor naval base, sent skeleton columns of soldiers, sailors and marines to patrol the coast of Oahu and guard against a surprise landing. Actually mobilized to defend Hawaii were 20,000 men, 17 sub marines, four light mine layers, two mine sweepers and 45 aircraft under Major General Briant Harris...
...last important city not occupied by Japanese troops, fell before the fierce frost-bitten fighters of General Jiro Ta-mon. Winter was Harbin's best defender.

...series of minor clashes, and prepared to meet and crush the first serious Chinese resistance, expected at Kowpangtze, 50 mi. north of Chinchow. Japanese troops camouflaged as snow men in long white gowns crawled forward eleven miles fighting every inch of the way. The temperature was 30 below zero. Japanese scouting planes reported a force of at least 3.000 Chinese "bandits" waiting to defend Panshanhsien.

...Last week he found it. Co-discoverers were Dr George M. Murphy of Columbia and Dr. Ferdinand G. Brickwedde of the U. S. Bureau of Standards in Washington. Under low pressure Dr. Brickwedde liquefied hydrogen by reducing the temperature. Then he allowed the temperature to rise.' At 437º below zero F. the liquid began to evaporate. Ordinary hydrogen atoms, being lighter, had risen to the top, evaporated first, leaving the heavier isotope in a richer mixture. At Columbia Professor Urey examined the hydrogen with a spectroscope, found lines only faintly visible in ordinary hydrogen, concluded they were caused...
