...gigaton" bomb-a nuclear weapon packing the power of a billion tons of TNT that could be detonated 100 miles off the U.S.'s coastline and still set off a 50-ft. tidal wave that would sweep across much of the entire North American continent? Was it a cobalt bomb that would send a deadly cloud sweeping forever about the earth? A "death ray" or a germ bomb? Or even an empty boast? Two days later Nikita Khrushchev said it wasn't nuclear, and, besides, he had been misinterpreted. For public consumption, his weapon had been cooled...
...statement suggesting that the U.S. could sow a sanitized zone of radioactive material across the Korean neck. Says he today: "It was thoroughly panned by scientific editorial writers." In any event, explains University of California Physicist Luis Alvarez, MacArthur was in error, since the half-life of radioactive cobalt is only 5.25 years, and the material could not be distributed from trucks. Says Alvarez: "You would have to have air dropped it, like leaflets, from a plane...
...works of art always stirs fears-vivid thoughts of a plane's crashing and burning with a considerable part of the work of Van Gogh, or the Pietà gently cracking in two along some unknown flaw line (although technicians, having bombarded the sculpture with X rays and cobalt 60 gamma rays, have discovered it to be the perfect piece of marble that Michelangelo said it was). Beyond fears for the safety of the art, its sponsors are given to worry over whether the likes of World...
...Peter's 17-year-old keeper to give him a brush and oil paints. Peter took to daubing like a duck to water. He painted all over the floor; he painted all over his keeper; he even painted all over a few canvases. He ate whole tubes of cobalt blue, leading to the speculation that its tart flavor was what inspired him to use it in his work...
...macroscopic level and has been verified on an atomic level. Physicists tacitly assumed that parity conservation also held on the subatomic level. In 1957 an experiment was performed which showed that parity was not conserved on the subatomic level. (The electrons emerging from the radioactive decay of cobalt were spinning more in one direction than in the other.) Physicists had assumed a law to be true in a situation where they had no right to. This was the second such faulty assumption which has been corrected in the twentieth century. Until 1926 physicists assumed that Newtonian mechanics (applicable to gloves...
