Cormack took the first step. A native of Johannesburg, South Africa, he became intrigued in 1956 by the difficulty doctors had in obtaining X-ray pictures of the brain. Because the cranium is so thick, they could make an X-ray beam "see" an abnormality only by injecting a patient with tracer dyes or air bubbles. When Cormack immigrated to the U.S. that year (he became an American citizen a decade later), he began exploring the physics of how X rays pass through differing body parts. Dividing this passage into cross-sectional slices, he found he could calculate the absorption...
...producing computers of the 1960s type. At the Shanghai Institute of Metallurgy we saw several impressive "clean rooms" under construction for the fabrication of "chips" containing the microscopic circuitry that is the brain of the modern computer. Some of these chips are being manufactured with new electron-beam techniques. Scientists are also experimenting with lasers. One intriguing project: a six-beam experimental laser device to produce power from thermonuclear fusion. Blessed with an abundance of the elements called rare earths, the Chinese are also becoming increasingly skilled at extracting them and putting them to work in many ways, for example...
Andy Young resigned [Aug. 27] with grace despite tremendous pressure. Two years from now when a battle-weary Israel finally sits down with the P.L.O. at the negotiating table, the framed picture of St. Andrew will beam down from the wall. People will then remember August 1979 and say, "Ah, that was his finest hour...
...PROJECT CALCULATES the application of available solar technology could provide 7 to 23 per cent of the United States' energy needs by the year 2000. The Project is not referring to massive, multibillion dollar power stations in space which beam electricity back to earth via microwave (a NASA pet project). Rather, it is talking about solar houses and hot water heating, windmills, wood burning and hydraulic power. Modeste A. Maidique, assistant professor at the Business School, writes...
...catch quarks in that playful activity, four separate teams of experimenters-involving 300 scientists from eight countries, including the U.S.-turned to West Germany's new PETRA colliding beam accelerator in Hamburg. The powerful machine accelerates electrons to energies of 15 billion electron volts and sends them barreling head-on into their antimatter opposites, particles called positrons, coming at high speed from the opposite direction. In the past, when such experiments have been tried with other accelerators operating at lower energies, the debris from the electron-positron collisions has consisted of only two "jets," or streams, of hadrons...
