...Motz's "millimeter-wave generator" is made up, first, of a linear accelerator that produces a pulsed beam of electrons about ? inch in diameter. The electrons, whose energy is 2,000,000 electron volts, pass into an "undulator," a silver wave guide that is held between 16 pointed steel teeth. The teeth set up separate and alternating magnetic fields, and as the electrons pass from field to field, they are made to oscillate, forming the desired waves less than one millimeter long...
Visible Radio. Dr. Motz can make them even smaller by increasing the speed of the electrons and therefore increasing the Lorentz contraction. Once he hitched his undulator to a large linear accelerator that sent out electrons at 100 million electron volts. From the business end came a beam of blue light. He had actually generated "radio waves" that were short enough to qualify as visible light. This stunt proved that the stubborn gap in the spectrum has been closed, but it is hardly practical. There are better ways of generating the waves of light and heat...
...Yale and the University of California announced a simultaneous windfall: $1,200,000 apiece from the Atomic Energy Commission, to build the first two linear accelerators ever designed for the acceleration of heavy atomic ions. For Yale, which has long been disturbed by the decline in the number of its science majors (down from 14.2% in 1940 to 10.3% in 1952, as compared with around 25% on comparable campuses), the AEC decision will provide a long-awaited shot in the arm: the great machine will undoubtedly place Yale "in the forefront of nuclear research in the nation...
Ever since 1900, when Archaeologist Sir Arthur Evans first discovered the hundreds of clay tablets in the ruins of King Minos' great palace at Knossos, Crete, scholars have been puzzling over a mystery. Some of the tablets bear a type of script that Evans named Linear A. Others bear symbols that indicate another language, which Evans called Linear B. What sort of language is it, and what do the tablets say? For half a century, scholars have been guessing...
...University of Cincinnati, who had come across 600 tablets while excavating the site of what is believed to have been the palace of King Nestor of Pylos, one of the great, Greek-speaking Achaean heroes of the Iliad. Since the Evans and Blegen tablets were in the same Linear B script, it was obvious that Knossos on the island of Crete and Pylos on the mainland of Greece had some close connection. But scholars have long assumed that the Achaeans were illiterate, for Homer gives little real indication that his heroes could write. The tablets, concluded the scholars, were therefore...
