...could be argued that Hué and Danang were abandoned not because South Vietnamese troops lacked ammunition and equipment, but because of a disastrous failure of leadership and loss of will to fight. Congressional delays in approving the latest request for supplementary aid were seen in Saigon as a demoralizing signal and in Hanoi as an encouraging one. But after a decade of direct involvement, $150 billion and 56,000 American lives, it is hard to see how a few hundred million dollars more would have been decisive...
...summer of 1967, Jocelyn Bell, a graduate student at Cambridge University's Mullard Radio Astronomy Observatory, discovered that a radio telescope she was monitoring had picked up some curious signals from space. She called the beat-like pulses to the attention of Astronomer Antony Hewish, the senior scientist. Hewish's team at first suspected them to be signals from an extraterrestrial civilization. But further inquiry proved that pulsars, as the signal sources were named, were actually long-sought neutron stars, small and incredibly dense collapsed stars. So significant was the discovery to the understanding of stellar evolution that...
...President's denunciation of Arab discrimination and the Church hearing, both of which took place on Ashland Chemical Co., Bendix Field Engineering Corp., Dresser Industries Inc. and International School Services. the same day, were clearly intended as a signal of bipartisan U.S. concern about the boycott. In Cairo, where the Arab boycott committee is currently holding its semiannual review of the blacklist, Mohammed Mahgoub, commissioner general of the boycott office, defended the list as "a legitimate means of legitimate self-defense." At the boycott committee's opening session last week, Mahgoub insisted that companies are listed only...
...list of nations modernizing their armed forces appears endless. According to a Brookings Institution study, even the Royal Brunei Navy has spent several million dollars upgrading its signal network. The international trade in nonnuclear arms now tops $18 billion annually?up from a mere $300 million in 1952, and a jump of more than 550% since 1964.* Moreover, this represents only a fraction of total military expenditures: in 1973 the nations of the world spent $240 billion to train, equip and maintain their armed forces. Until a few years ago, nations usually
...bubbles. The U.S. answer: new ECM techniques that can fool enemy radar into "seeing" a plane in the sky some distance away from where it actually is. Still largely cloaked in secrecy, the technology depends on mimicry and deception. Once a plane's instruments sense that radar signals are bouncing off it, they identify the type of pulses, memorize them and then retransmit them. But the apparent radar echo is sent back with a different interval between pulses, or with the pulse altered-or both. Ground-based radars that decipher the new signal are likely to locate their target...
