...that the U.S. had allocated funds to research on atomic energy. The Germans quickly set up their own project. But, says Heisenberg: "Public interest in the problems of atomic physics was negligibly small between the years 1933 and 1939." [the Nazi prewar period]. Germany had no cyclotron, and only two "adequately equipped laboratories." Lacking proper tools, her physicists were seriously handicapped...
...been frittered away. The Clinton Laboratories pop them into stainless steel and lead containers (weighing up to 1,600 Ibs.) and speed them by truck to the Knoxville airport. Prices vary widely. Carbon 14, one of the big sellers, costs $50 per millicurie* (if made by the old-fashioned cyclotron method, it would cost $1,000,000). In the past year Oak Ridge made 1,092 shipments to 161 U.S. users, none to foreign countries...
...Oxford Street, in a job which Edward Reynolds '15, administrative vice president of the University, called a "normal expansion," workmen are laying larger electrical cables necessary to carry the increased lead caused by the new cyclotron and other scientific apparatus in nearby buildings...
Successful Debris. Previous cyclotrons, they explained, had just chipped away at the atom, knocking off two or three small particles. But the 184-incher's bullets cause such havoc in atoms that researchers have so far been unable to sort out all the debris. Said one of the California scientists: "With the old cyclotron of 225 tons [60 inches], we could knock two or three floors off a 50-story building, or maybe add a floor or two. But with the new cyclotron, we can knock that 50-story building into a flock of four-room bungalows, with...
Sample smash: an arsenic atom (atomic weight: 75) had 21 particles knocked off by a single blow, and was reduced to radioactive cobalt (atomic weight: 54). When the new cyclotron bombarded an oxygen atom (atomic weight: 16) with neutrons, the light atom split into five pieces (see cut; the arrows point to the five-way split of the oxygen atom, the streaks indicate the path of atomic chips...
