...Tomiyasu and his colleagues have also learned how to make laser light carry information. Modulated in much the same manner as radio waves, its high frequencies can handle far more intelligence than any microwave beam. Each five-thousandth-of-a-second burst of light can theoretically be made to transmit coded information that would be the equivalent of 200,000 words...
...other obstructions with out building repeater stations on top. They set up a weak, 15-watt transmitter 45 miles south of San Jose, Calif., on the other side of Loma Prieta, a 3,798-ft. peak in the Santa Cruz mountains. Then they pointed their transmitter's beam of 1,855-megacycle waves in the general direction of San Jose. When the beam was aimed too high, its waves shot off into space; when the beam was too low, its waves were lost in the mountainside. But when the beam was angled just right, its waves hit the upper...
Begun at Harvard's biological laboratories last September, Porter's current research uses a new $40,000 electron microscope. The shadow picture produced by introducing the cell specimen into a beam of electrons has a resolution of one fifty-millionth of an inch. Porter in 1945 made the first electron microscope photograph of a cell...
Since radiation is a potential hazard in space flights, Kjellberg indicated that, "The possible role of biological studies with the proton beam is already of interest to the National Aeronautics and Space Administration...
...recurring hepatitis, worked 60 hours a week for two years under such rigid security that outsiders still do not know the boat's full specifications. But her 30-ton weight matches that of such U.S. 12-meters as Vim and Columbia; so do her 11-ft. 10-in. beam and her 70 ft. of overall length. The yacht's decks are of Canadian cedar, overlaid with waterproof blue fiber glass. Her hull is of Honduras mahogany, covered with six coats of white paint, decorated with a thin gold stripe and the five stars of the Southern Cross...
