...building a 25-ton magnet for a new eyepiece and plans a still bigger one. He and his assistants are experimenting with the university's new accelerator that should soon be splitting electrons at the highest speed ever reached: 186,000 miles a second, only a fraction slower than the speed of light. With his new microscope, which will put the atomic nucleus in even sharper focus, Hofstadter may well probe to the innermost limits of matter...
...wants to buy one share of stock may do so by making a small monthly payment (minimum: about $40) to his broker. The money will be turned over to a bank, which will pool it with funds of other investors, buying the stock and crediting the investor with whatever fraction of a share his payment represents. Funston thinks the plan will appeal to small investors for two reasons: 1) it will enable them to buy stock without first accumulating the whole amount, and 2) it will involve lower commissions than the average 7.5% charges made by investment trusts...
...tubers can be eaten by man. Another trouble with conventional food plants: when they are young, they cover only a little ground. A field of thriving, knee-high corn may delight a farmer, but to a chemist's eye it is shockingly inefficient. It utilizes only a small fraction of the sunlight falling on the field...
...where it quickly runs out of carbon dioxide or falls prey to microscopic predators. The best way to handle it is to circulate it rapidly through wide, flat tubes of thin plastic. The cells utilize sunlight most efficiently when they are exposed to its full intensity for only a fraction of a second at a time. So the flow of the culture must be turbulent, bringing the cells to the surface for a short time, then carrying them down into shaded depths. The "crop," a bright green paste, is harvested by settling or centrifuging. It spoils quickly if not preserved...
...rush was so great that the stores sold out in the first hour and had to be replenished. Lining up in block-long queues, hungry East Berliners bought 25,000 kilos of potatoes, 12,000 liters of milk at a fraction of the prices charged in their Communist paradise (to encourage customers, Kressmann accepted East zone marks at par, instead of at the usual price of five East marks to one West mark). Anyone who could produce an East German identity card had his choice of five oranges (at 1? a piece) or two pounds of cherries (3? a pound...
