...telescopes have become increasingly sensitive. They can listen to exploding galaxies near the mysterious edge of the universe, but the slightest interference puts them out of action. A signal from a TV station thousands of miles away can be reflected off an airplane, or a satellite, or even a layer of air, and reach a radio telescope far over the curve of the earth with enough strength left to knock a delicate recording needle right off the scale...
...University should not wait until embarrassment forces it to hire a Negro professor. The fastest way to build up a "pyramid" of academic excellence is not layer by layer. People in the highest levels inspire and give hope to those...
Thanks to the nation's miraculous eco nomic boom. West Germans today are more concerned with paychecks than with princely comings and goings. But the country's economic and social transformation has failed notably to produce a unified, national Fuhrungsschicht (leadership layer) in place of the old aristocratic ruling caste. The result is a confused and confusing society in which, says Sociologist Ralf Dahrendorf, there is not one class of Prominenz but "a multitude of competing groups." The "pyramids of power" include the church, the military, local government and such venerable universities as Tubingen, Gottingen and Heidelberg, where...
...very long, low-frequency waves from the universe never reach terrestrial receivers because they are blocked by the earth's ionosphere, the outer layer of the atmosphere composed of ionized, or charged, molecules and free electrons. These long radio waves convey a great deal of information--about the origin of cosmic rays, magnetic fields in space, the mechanism of solar flares, and radio storms on Jupiter, for example. To record these long waves, Harvard, in cooperation with the Air Force Cambridge Research Laboratory, has built and orbited a series of small radio telescopes above the opaque ionosphere...
...microscopic holes into synthetics to enable them to "breathe." Both firms shy away from calling the synthetics plastics; Du Pont is calling its product a "poromeric material" (meaning full of microscopic holes) until it can decide on a trademark name. The shoe material is made in two or three layers: outside is a polyvinyl chloride film that can be treated to look like any leather, from cordovan to suede; next is either a layer of nylon or orlon (Du Pont) or one of polyurethane foam (Arnav); the shoe's inside layer is one of the standard lining materials...
