...names of the men who were attracted to Marxism in their youth during the twenties and thirties reads almost like a roster of influential thinkers in modern America: Daniel Boorstin, Sidney Hook, Daniel Bell, Ernest Hemingway, Edmund Wilson, Granville Hicks, Reinhold Niebuhr, Daniel Aaron, and Murray Kempton, to name a few. Most of them ended up as respectable liberals. But even more intriguing than these liberals are those ex-Marxists who made a complete about-face, ending up as right-wingers. Smaller in number, they have been at least as important to conservatives as the others have been to liberal...
That command-shouted in 1876 by Alexander Graham Bell and heard in another room by his assistant, Thomas Watson, over Bell's first working telephone, was repeated in Boston last week. The occasion: an American Telephone and Telegraph banquet commemorating the 100th anniversary of the telephone. To demonstrate a century of progress, the teen-age descendants of Bell and Watson who re-enacted the historic moment then placed a call that was transmitted between two modern telephones not by electrical current or radio waves but by a beam of light passing through a hair-thin glass fiber. Proclaimed
...diverge. Miniaturized lasers make it possible to couple powerful light beams accurately with hair-fine glass fibers. Another was the perfection, by Corning Glass Works, of a fiber of glass so pure that it could transmit light long distances. The third accomplishment was the devising, by engineers at Bell Labs and elsewhere, of methods of integrating fiber optics into modern telephone systems...
Field Test. Bell Labs is currently field-testing an experimental fiber-optics communications system in Atlanta. But much work must still be done before glass replaces copper in regular systems. Engineers are still trying to find efficient ways of joining the threadlike fibers together. Researchers are working to increase the lifetime of the lasers used to generate the fine beams upon which optical communication depends; the lasers now in use have a projected lifetime of 100,000 hours; researchers would like to increase this to 1 million hours. Scientists are also developing integrated optical circuits, the optical equivalent...
...response is unique to each individual. One person can live through years of bombing with no effect. In another case, something as trivial as the ringing of a bell provoked a fatal attack in a healthy young woman," Lown said...
