...each boat a radioman worked hour after hour, sent into the ether offers to Dr. Gunnar Horn, scientist aboard the Bratt-vaag, for "exclusives" on the story, pictures, diary. Each pleaded with him for a midocean rendezvous at a designated point in the Arctic. Each could only hope and pray that the message would be received, that the Brattvaag would be there, or that they would happen upon...
Above the upper reaches of the stratosphere, higher than man has ever studied, stretches the Kennelly-Heaviside layer of ionized ether which acts as a conductor (or reflector) of radio waves. If man could study these regions he might gather valuable meteorological data, possibly discover new air travel lanes for aircraft of the future...
...great step came when Newton (1642-1727) gave Space a definite physical reality in his theories of force accelerating bodies, the movement being measurable in reference to a really rigid body. The introduction of "ether" by Faraday (1791-1867) and Maxwell (1831-79) to explain their electro-magnetic field theories was the last great step before Einstein's relativity theories...
...Oliver Heaviside and A. E. Kennelly formulated in 1902 their "radio roof" theory: that Earth is surrounded by a sac of ionized ether which acts as a reflector (or conductor) of radio signals. During daytime the sun's light pushes this layer closer to Earth, lessens efficiency of reception. At night the layer rises, reception reaches maximum efficiency...
...disc on the M. I. T. instrument was keyed to a three-octave board, reproduced deep pipe organ notes. Unlike Leon Sergeievitch Theremin's "ether music" box (TIME, Sept. 30), Hardy & Brown's development does not slide from one note to another, slurring the intervening ones...
