Golovchenko's appointment comes in the wake of the recent promotion of Associate Professor Robert M. Westervelt to another joint tenure position in the Department of Physics and the Applied Physics Division. Westervelt also works in the field of Condensed matter and semiconductors surfaces...
Physics professors said yesterday that both Golovchenko and Westervelt will be working in an increasingly active field at Harvard...
...when a nuclear bomb explodes in a vacuum, about half of its energy goes into invisible X rays. These hit the atmosphere and make its oxygen and nitrogen fluoresce in characteristic wave lengths that can easily be distinguished from the spectrum of sunlight. When Los Alamos Physicist Donald R. Westervelt learned about this, he designed a detection system based upon it. A few dozen of his detectors spotted around the earth would be an adequate network. Some of them would always be under clear skies. In daylight they would detect a one-megaton burst 2,000,000 miles from...
...problem still remaining is to prove that no natural phenomenon will look like a space test to Westervelt's detectors. The model at Los Alamos has already passed one test: it is not fooled by lightning. Next month it will be moved to Fairbanks, Alaska to see whether it cries a false bomb scare when a strong aurora shines in the night sky. Only if it can distinguish a nuclear explosion from all natural events will the detector be recommended for international test watching...
Died. Brigadier General (ret.) William Irving Westervelt, 83, Texas-born artillery expert who recommended in the early '20s the modernization of field weapons finally undertaken at the beginning of World War II, retired in 1927 to direct research for Sears, Roebuck & Co.; in Brattleboro...
