Horowitz looked up at the counters and scopes that caught the radiation bouncing off the apple, measured pulses, and eventually spit out sets of numbers that revealed which heavy elements were present. He made some quick calculations, and detected iron and calcium--he expected them. He looked at a third set of numbers, and found that it was arsenic--about 30 parts per million...
...traditional view is that the first really large-scale attempts at underground mining, in which extensive shafts and subterranean galleries were used, were not made until the time of the Romans, who mined everything from Spanish silver to British iron and Near Eastern copper. Rothenberg's discovery just about destroys that theory. From the stone hammers, bronze chisels and a cooking pot found in the labyrinthian tunnels of the Negev mine, he concludes that the mine dates back to 1400 B.C. -near the end of the Bronze Age and more than a millennium before Rome's large-scale...
...small pieces and placed in large, saucer-shaped pits. When winter rain flooded the pits, the lighter malachite swirled to the surface and could be more readily separated from the other rock. Half a mile away there were 13 furnaces, where the Bronze Age metallurgists smelted the ore, using iron as a flux (a substance that combines with impurities, forming a molten mix that can be easily removed). Bronze Age miners were able to produce 22-lb. copper ingots that were 97% to 98% pure, a degree of purity not exceeded until modern times...
Good News might be the ideal way to greet the New Year - if only this were 1927. After nearly a year on the road, the revivalists have managed to iron out all the show's wrinkles. They are now presenting them onstage. The ancient flapdoodle of a plot (updated to the mid-'30s) hinges upon the success of a college football team, a situation the Marx Brothers sent up for ever in Horse Feathers of 1932. The De Sylva, Brown & Henderson score, much of it shanghaied from other mu sicals, is loaded with bolts of melody...
Four days of practice ahead separate Harvard from the slightly ruffled Ivy favorite Penn. The Quakers came up on the short end of a 50-49 match against Princeton January 4. Sanders will try to iron out defensive problems and look for the return of a healthy Needleman to the IAB Friday night...
