“Sea Water” Metal Used to Make Plane Sea and air combine in a five-seater British personal plane made of magnesium alloy, an element extracted from sea water. Though the metal weighs less than the lightest aluminum, the wings in bending tests have withstood deflection five times greater than is required. Expected to fly over 200 […]
THE DEER and bushy-tailed squirrels that live on Mount Wilson have been watching a strange new forest of "bat-wing" radiators and pylon antennas replace the trees that formerly grew on the mountain top. Seven new television stations and five new FM stations are grouped together on top of a small ridge not far from the famed Mount Wilson Observatory where the 100-inch Hooker telescope is located. Except for one transmitter that is a short distance from the others, all the stations are within an area about half a mile long and a couple of hundred yards wide.
By F. L. Brittin, S.M.,I.R.E. ANYONE can build and operate this simplified Geiger-Mueller survey meter, which is an instrument for detecting the presence of radiations emanating from radioactive substances such as valuable uranium and radium. Specifically, the Geiger-Mueller tube, which is the most important component of the instrument, detects X-rays, cosmic rays and gamma rays. Beta rays can also be detected by Geiger tubes with very thin cathode walls.
Nature needs help as a hungry world calls for food. "Blueprints" drawn up by animal engineers promise to give us more meals from each animal PLANS for the 1950-model beef critter already are on the drawing boards of the nation's animal engineersâ€”and never did you see such a streamlined creation! Built with square lines, low to the ground and with shorter "wheelbase," this advanced model will carry more T-bones and tenderloins for its weight than any animal yet to appear on American ranges.
PROFESSIONAL and amateur prospectors by the thousands are literally leaving no stone unturned in the great uranium rush of '49. The ores which yield atomic energy are being sought in every part of North America. Excited by reports of government rewards, many of the prospectors are wasting their time in localities where uranium of worthwhile quality can hardly be expected to be found, though there is always a chance that someone may upset the convictions of mining engineers by making a "strike" in a new region. The Atomic Energy Commission wants to see samples of any ores suspected of containing valuable amounts of radioactive materials, but prospectors are urged to make reasonable tests of their samples before submitting them. Misinformed or overly enthusiastic people have submitted hundreds of samples of worthless rocks, including ordinary concrete, to the commission.

By Wayne Whittaker THE THIN FELLOW you saw in the post office the other day with that worried look might well have been one of the millions of stamp collectors in this country. He has had a harrowing yearâ€”1948â€” trying to keep track of the special stamps that have rolled from the presses in the U. S. Treasury's Bureau of Engraving and Printing, Washington, D. C. The last Congress may go down in history as the "Stamp Act" Congress. By congressional authorization, its members sponsored a new stamp on the average of every other week in 1948. Stamp dealers groaned. Stamp collectors groaned. Officials of the bureau groaned loudest of all, but Congress went happily on its way paying tribute to everything from the poultry industry to the Gettysburg Address.
