Since late last year, the silver-short U.S. has been forced to mint silverless "sandwich" quarters and dimes containing a central layer of copper between two thin slices of copper-nickel alloy. Now another Government agency has suggested a more direct solution: find more silver. To aid prospectors, U.S. Geological Survey scientists have designed and successfully tested a "silver snooper," a device capable of locating silver deposits buried as deep as three feet below the ground. By shooting a stream of neutrons into the earth, the snooper turns the silver temporarily radioactive, causing it literally to signal its presence...
...result, the Government, which sells coins to banks at their face value, will soon be minting unheard-of profits. With the new copper-nickel alloy coins authorized by the bill, the cost of turning out a dime will drop from 9.5? to .6? quarters, from 23.6? to 1.5? and half dollars, from 47.3? to 26.5?. Revenues from coin manufacture will leap from some $100 million in 1965 to $1 billion...
shortages of strategic materials contained in the Paley Report (TIME, June 30, 1952), none were more pessimistic than the facts about U.S. nickel supplies: U.S. production was almost nil, yet U.S. nickel requirements would be doubled by 1975. Last week brighter news about the U.S. nickel outlook came from Canada. Falconbridge Nickel Mines Ltd. began development of a new mine in northern Ontario on an estimated lode of 10 million tons of rich copper-nickel ore. A nine-year U.S. Government contract insures that practically all the mine's output will...
Gruff, honest Bridgman assigned Robert to a project involving a copper-nickel alloy. Oppenheimer built a furnace, made his alloy, completed the study with sufficient precision for Bridgman to publish the findings. Says Bridgman: "A very intelligent student. He knew enough to ask questions." After hours, at the Bridgman home, the conversation ranged far & wide, giving Oppenheimer chances to display his often irritating erudition. Once Bridgman identified a picture as a temple at Segesta, Sicily, built about 400 B.C. Young Oppenheimer quickly set his professor straight: "I judge from the capitals on the columns that it was built about...
