...reflecting telescope composed of six 72-inch-diameter mirrors should go into operation at SAO's Arizona station this summer, although in Fall 1975 completion of construction was expected by Fall 1976. The six mirrors, focused together by computer, will equal the light-gathering capacity of a 176-inch reflector--second in size only to the 200-inch reflector at Mt. Palomar, Ca. The cost of the multi-mirror telescope, borne partly by the University of Arizona, will exceed five million dollars. The telescope housing alone cost over $1.3 million. Herbert Gursky, the Center's associate director for optical...
...Friis, 83, radio-communications pioneer whose work helped make possible, among other things, modern radio reception and microwave transmission; of a stroke; in Palo Alto, Calif. Born in Denmark, Friis became a leading research scientist with the Bell System, eventually holding 25 patents, including one for the famous horn-reflector antenna of microwave systems first used in satellite communication. Highly regarded as a teacher of other scientists, Friis also supervised the work of the late Karl Jansky, founder of radio astronomy...
...distinguishable surface features. But stars other than the sun are so distant that even the closest one* looks like a mere pinpoint of light through the most powerful telescopes. Now astronomers at Arizona's Kitt Peak National Observatory have improved the stellar image. Using their new 158-in. reflector-the world's second largest telescope-in combination with a novel, computer-enhanced photographic technique, they have produced the first pictures of a star that show some surface detail...
...universal art. It speaks in a speechless tongue that is immediately comprehensible to everyone. It knows no language barriers. The possibility of misunderstanding does not exist. In a troubled world, where men are working constantly to determine some common ground of understanding, it follows that the theatre--always the reflector of the times--should be influenced to reactivate this medium of universal symbols...
...crossed a vacant lot on her way to school. Most schools found it impossible to adjust their hours because of union contract rules, the after-school commitments of school bus drivers and inconvenience to working parents. Thus, many school authorities recommended that children wear light-colored clothing or reflector patches. The Connecticut General Life Insurance Co. began giving away patches and distributed 500,000 in two days. In Fairfax County, Va., guards used highway flares to guide children across streets. Elsewhere, children lit their way to school with flashlights, lanterns and even candles...
