Navy Contract Number One has gone to Professor Emory L. Chafee for research in electronics. One of Chafee's jobs is to invent new kinds of vacuum tubes--he is now working on one that spins a light wave around a beam of electrons. The two interact to strengthen an electric current...
They built three snowhouses. Each was about eight feet high, 10 ft. by 14 ft. in breadth. They used their parachutes for roofs, stripped the ailerons from their plane to hold them up. They used the C-47's plywood ventilator for a center beam (it broke), and the power plant for lighting. Air Force planes dropped them everything they could use-playing cards, whiskey, clothes, magazines, a Christmas dinner of roast turkey and pumpkin pie, a Christmas tree. Some even talked to their families in Greenland by radio...
...good deal less about Diderot than they do of Rousseau. Students who learn of Diderot in college are apt to classify him as one of the great French Encyclopedists, learn too little of his novels, plays and essays. If they remembered him at all it was as a minor beam in France's 18th Century age of enlightenment. Last week, Denis Diderot was having his innings...
...around closed circuits. One kind of human memory is believed to depend on a similar system: groups of neurons connected in rings. The memory impulses go round & round and are called upon when needed. Some calculators use "scanning" as in television. So does the brain. In place of the beam of electrons which scans a television tube, many physiologists believe, the brain has "alpha waves": electrical surges, ten per second, which question the circulating memories...
...feature of the old-style ranges is that airliners have to fly directly from station to station. This causes traffic congestion. In bad weather a long-distance plane cannot strike off cross-country to avoid the neighborhood of a busy airport. If it does, it gets off the beam and may have to go through time-wasting maneuvers to get back on again...
