...human eye were tuned to longer wave lengths of radiation, it would be able to see radio waves. The ethereal wiggles that gird the globe with speech and music are part of the same electromagnetic spectrum which includes visible light, ultraviolet and infra-red radiation, x-rays, gamma rays from radium. Hence under ideal conditions radio waves travel at the velocity of light - about 186,270 mi. per sec. - and for many a year radiomen assumed that wireless signals always traveled at that pace in their journeys around Earth. Last week Dr. Harlan True Stet son of Harvard informed...
...Durham, N. C.'s Duke Hospital, Surgeon-in-Chief Julian Deryl Hart last week braced himself to answer a barrage of questions excited by a report in Modern Hospital concerning novel use of ultraviolet light as an antiseptic agent in operating rooms. Over his operating table Dr. Hart had rigged a grid of light tubes which project an invisible light which within five minutes effectively kills almost all germs within a radius of five feet...
...speaks Loring B. Andrews '25, instructor in Astronomy, in the May 1 Alumni Bulletin. His thesis is that ultraviolet radiation may affect not only plants, trees, and over a period of years the earth, but also that it has a direct effect on the bodies and minds of humans...
...astonishing new factory: one five-acre room without windows. Executives and machines were to work side by side, their noises deadened by sound-absorbing ceilings; machines were to be bright orange against black floors to prevent accidents by making everything conspicuous; walls and ceilings, part blue to reflect ultraviolet rays, part green to energize workmen, part white for light and cleanliness. Two hours before closing time, flagging workmen were to be daily revived by a burst of stirring music. But the five-acre room, finished in 1932, still stands empty and idle...
...Dellinger now believes that high-frequency daytime reception improves with sunspot activity, possibly because increased ultraviolet radiation from the sun at such times makes more ions in the ionosphere. The magnetic shifts resulting from the ultraviolet bombardment, however, may cause delayed interferences with low-frequency reception and night reception in general...
