Many a scientific cloud on the horizon promises, or threatens, to revolutionize postwar living. One is the "microwave." Microwaves lie in the largely uncharted area of the radio spectrum above the part now used for conventional sound and television broadcasting (upper limit: roughly 80 megacycles). Microwaves are used in radar, and most of the wartime discoveries about them are still military secrets. But radio engineers have found their potentialities dazzling. This week plain citizens were given a glimpse of what the engineers envision...
Beyond the Horizon. This sweeping scheme was outlined by Raytheon's engineer Joseph Pierson as he applied for three microwave bands, at 1,900 megacycles and above. Said Pierson: if it gets these allocations, Raytheon will start work at once on the eastern (Boston, New York, Washington) and West Coast terminals of the microwave system. Raytheon plans to build a string of stations on western mountain tops, from Mt. Adams, Washington, to Mt. Whitney, California. Eventually the east and west terminals will be connected by chains of relay transmitters at about 30-mile intervals across the country...
Like the short radio waves (about 80 megacycles) now used for television, microwaves (over 300 megacycles) cannot be sent beyond the horizon. But Raytheon's engineers say that microwaves have two advantages for transmitting pictures: 1) they can be relayed more easily, by means of automatic pickup and amplifying stations in towers about 30 miles apart, and 2) they can carry a picture on a narrower band in the spectrum, thus providing a great many more channels for transmission...
...First Half. In the Coral Sea came history's first "battle beyond the horizon," in which carriers sent aerial artillery to strike at each other across hundreds of miles of water. Nimitz lost the Lexington but saved Australia and New Zealand...
After that there is nothing on the horizon but a distinct golden haze already reflected in the eyes of some of the more confident of our brothers such as "Weeping Walter" Blatt. Of course there always will be people like the local ROTC who would dispute our primacy by having their commissioning the day before ours, but consolation will lie in our proud oak leaf insignia which, together with the Supply Corps, is 150 years old this Friday and which, incidentally, was adopted in 1785 in honor of the oaken fighting ships on which the Corps first served
