...light-television apparatus, developed by Dr. Ernst Frederik Werner Alexanderson, derives its carrier wave from a high-intensity arc light. The carrier wave is modulated by the Alexanderson scanning device which translates a picture or scene into electricity (TIME, Jan. 23, 1928). As with the Taylor system, anyone who has the proper receiving apparatus and can see the Alexanderson beam, can also see what the television apparatus is seeing...

...Alexanderson arc, however, can modify as well as modulate the carrier light waves. Hence receivers could tune in on properly differentiated sending lights...

Both systems are still playthings. Yet some day, Dr. Alexanderson imagined last week, "we may see television broadcast from a powerful arc light, mounted atop a single tower high above the city. . . . These light waves can be received at relatively short distances only, perhaps ten miles; each community could then have its light broadcasting system. Light broadcasting may have the same relation to radio broadcasting as the local newspaper has to the national newspapers...

...three-dimensional geometry the ratio of an arc to its chord is one. (i. e., the arc can become so small as to coincide with its chord.) Professor Edward Kasner of Columbia University projected a four-dimensional geometry, found the ratio could be less than one. More important, he found that the ratio does not diminish steadily as the length of the arc is diminished, but in sudden jumps-from 1 to 0.94 to 0.86 to 0.80. . . . The changes in subatomic energy occur in lumps, and these changes he found to correspond to the diminishing jumps of Ratio of Arc...
