...that accumulates in all organisms while they live and decays at a known rate once they die. But it measures it in a different way. Current dating methods determine the age of an object indirectly, by measuring its carbon-14 radioactivity. The new technique being developed by Professor Harry Gove of Rochester and his fellow researchers measures the amount of carbon 14 directly. The scientists place a sample of the object to be evaluated in Rochester's tandem Van de Graaff particle accelerator. The machine separates carbon 14 and carbon 12, an atom that also accumulates at a steady...
Tiny Samples. Gove believes the direct measurement system, which requires as little as one-hundredth of the material needed for current dating tests, will eventually win wide acceptance. He and his colleagues have accurately determined some test samples to be 70,000 years old. With more work, they believe, they can push radiocarbon dating of tiny samples back to 100,000 years...
...year, summer included. Valley View uses its classrooms efficiently, dividing the children into four groups that have staggered schedules of nine weeks on and three weeks off. Thus the school has been able to absorb 1,760 new pupils without putting up a new building. Assistant Superintendent James Gove says the plan is "the equivalent of adding 75 classrooms worth $7,500,000 without spending a cent...
