With a double heat shield on an ICBM warhead, for example, the outer shield can be made to take the brunt of X-ray damage, leaving the inner shield to protect the warhead as it descends through the atmosphere. A neutron-blocking layer of paraffin or liquid hydrogen can prevent the uranium trigger from fissioning prematurely. Installation of more rugged electrical components and addition of bypass circuits reduce the possibility of damage from the surge of current caused by an electromagnetic pulse...
...lead the Los Alamos scientists in their race to give the U.S. the world's first nuclear weapon. It was a task he discharged brilliantly, and then in peacetime, as chief adviser to the A.E.G., turned around to argue bitterly against carrying on with the vastly more powerful hydrogen bomb. His stand, along with disclosure of his past left-wing association, stirred a nationwide controversy that culminated in 1954 with the revocation of his security clearance, after which he returned to academe as director of Princeton's Institute for Advanced Study, seeking, as he recently said, "an understanding...
...without cracking. The increasing complexity of astronavigation has fostered the development of swifter and smaller computers that find no end of applications on earth. The fuel cell used to supply electric power for Gemini spacecraft is being developed for commercial use, and its production of electricity from oxygen and hydrogen without burning hydrocarbons may be one answer to the smog problem that is increasing all over the world. Some scientists are already speculating about giant orbiting mirrors to light up a battlefield in Viet Nam or melt icebergs, free ice-locked harbors and shift storms from their natural courses. Weather...
...news, gasped Madrid's daily Pueblo, "has come like the explosion of a hydrogen bomb, like the alighting of 100,000 fiery angels." Or so it seemed to Spain's aficionados. The man who dropped the bomb, Bullfighter Manuel Benitez, 29, better known as El Cordobés, seemed unshakable in his decision. The night before, he explained, "I fell asleep, but suddenly at 3:20 in the morning I leaped out of bed ready to break the news. Providence told me to do this." So, after seven professional years that earned him some $7,000,000 plus...
...Martian surface, the spectrograms were of such high quality that they revealed unexpected absorption lines which had been indistinguishable in spectrograms recorded by less sensitive instruments. After careful analysis, Kaplan concluded that many of the absorption lines could have been caused only by reflected sunlight passing through hydrogen compounds in the Martian atmosphere...
