Since laser light can be concentrated into a thin beam that barely spreads out at all, Professor Louis Smullin and Dr. Giorgio Fiocco, the M.I.T. engineers who performed the experiment, estimate that the laser's light diverged only about two-thirds of an inch for each mile of its quarter-million-mile journey to the moon. When it reached the moon's mountains, the laser beam lighted faintly a circular area only two miles in diameter...
Starting quickly the Crimson first stringers piled up a 5-0 first period lead. The attacking trio of Lon Williams, Grady Watts, and Woody Spruance, so effectively sniffed by Princeton Saturday, was back on the beam...
...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...
