...Using gamma radiation of an extraordinarly precise wave-length, the scientists have attempted to send the radiation through a distance sufficient to induce a gravitational change of wave length which Einstein's theory predicts. Until the experiment was suggested, the theory's only verification came from astronomical observations whose accuracy was not great enough to establish the principle beyond doubt...
...Citroen family. With new capital, the company plunged into research, soon turned out a tabulator capable of writing 150 lines a minute when other tabulators were only half as fast. During the war its engineers designed a postwar line of advanced electronic computers, the first of which, the Gamma 3, appeared...
Using germanium diodes instead of tubes," the Gamma 3 proved a versatile workhorse computer, led Machines Bull engineers to design the new Gamma 60 line. The Gamma 60s, coming out in January, are the last word in "simultaneous" computer design, are as far ahead of the Gamma 35, says Callies, as a pipe organ is ahead of a flute. Costing $1,000,000 to $3,000,000 each, depending on the number of components used, the 60s can make 10,000 additions, 3,333 multiplications, 1,666 divisions and 10,000 mathematical decisions each second. One part of the computer...
