...australis, perform beautifully, magnetic compasses oscillate to and fro over a small amplitude centered at their normal position, and long distance radio reception is either improved or hampered. In connection with the last of these it should be said that whether reception is improved or hampered depends upon the wavelength of the signals and other factors related to radio transmission. The assumed validity of a correlation of electrical phenomena on the earth and sunspot activity is thus established in a straight-forward manner...

Perfection of the instrument which transmits its signals on the ultra-short wavelength of 5 meters, was made possible by a study of high frequency radio transmission and receiving between the weather station on top of Mount Washington and Blue Hill...

...Lick Observatory, who produced photographs taken during a solar eclipse showing stars near the sun's rim appar-ently displaced from their true position. The other statement was that light moving against a gravitational field should be "stretched" by the strain-i. e. suffer an increase of wavelength, which should displace spectrum lines toward the red (long wavelength) end. Thus, light winging away from a heavy star should show a definite redshift. Obstacle to confirmation was that another and unrelated spectrum shift existed (the Doppler effect), due to the motion of the star away from or toward the observer...

...short wave station, equipped with a beam antenna which allows the broadcasting of radio waves in a straight line, has been constructed on the roof of the Physics Building by Harry R. Mimne, assistant professor of Physics. With a wavelength of five meters and an antenna which can be raised or deflected on a horizontal axis as well as turned from side to side, it is the only station of its kind in the country. It began operation two weeks ago. Its purpose is purely experimental, and at present, it is carrying on communication with the short wave stations...

...ultra-violet.* This point on the ultraviolet side is 2,000 units lower than in other ultramicroscopes. If organisms never seen by human eye do exist in the filtrable viruses of common colds and infantile paralysis, they might be detected by light of such short wavelength. Light of longer wavelength they escape as minnows escape a loose-meshed...
