...thermocouple, two pieces of unlike metals are joined. When the joint is heated, a feeble electric current is generated, flows through a wire connecting the cold ends. Chief obstacle to commercial use is the difficulty in finding metals that can operate efficiently at the high temperature required for large-scale power production (TIME, April...
...study of the Freshman Year may well be one of the next large-scale projects of the Committee on Educational Policy. CEP members have shown an increased interest in this problem for several weeks, although formal consideration is still pending...
...rate, it is apparent that the proposals so far advanced by both the Administration and the Democratic leadership lack imagination or a sense of urgency. It is difficult to argue that the condition of the economy necessitates large-scale public works projects, but it is clear that unemployment is a more pressing concern than anyone has so far admitted. If Secretary Mitchell's goal of "full employment"--unemployment of only three million--is to be realized, Washington needs to come up with more far-seeing responses than have yet developed...
...further wide-scale revision of the present Army ROTC program has also received Bundy's approval and is now awaiting action by the government. The plan recommends a reduction in Military Science courses to give the students more freedom in planning their schedules and "hopefully, to draw a larger number of undergraduates into the program," Col. Armstrong said...
...called a thermocouple) when the metals are held at different temperatures. Since such a system has no moving parts, the thermocouple is theoretically an ideal way to generate electricity. Catch has been that most suitable materials cannot stand the high temperatures needed to generate thermoelectric power on a large scale. By combining indium (a soft, silvery metal used in dental alloys) with arsenic and phosphorus, the Westinghouse researchers developed a new chemical compound that performed thermoelectrically at temperatures between 850° F. and 1,500° F., achieved an estimated 10% efficiency. Compared to the 40% efficiency of the biggest...
