...scientists working under Dr. Kenneth M. Evenson at the National Bureau of Standards in Boulder, Colo., have measured c with new accuracy. Working with a laser beam-pure light of a single frequency-they have refined the measurement of light's speed to 186,282.3960 miles per second. In effect they reduced the accepted speed by roughly 144 feet per second. This may not seem important to camera fans worrying about exposure, or yachtsmen timing a flashing light on a dark night. But it could make a considerable difference to scientists calculating the precise landing site of an astronaut...
...Jose is no innocent victim of Carmen's wiles; to her obvious fascination, he is a brute with enough temper to kill. With the hauntingly Iberian sets by Czech Designer Josef Svoboda, one can believe that Seville is steaming hot (it literally is: 280,000 watts of light beam down on the cast from behind the proscenium), that Pastia's tavern is a fun place to go, that the mountain pass is desolate enough to make people fall out of love, as Carmen and Jose do. One can, in fact, begin to believe again in opera itself...
...create a video image, the disks have to spin up to 1,500 revolutions per minute; at that speed a needle whips through them too fast. The Philips system, developed by Video Research Chief Hajo Meyer, Dr. Piet Kramer and their 25-person team, uses a helium-neon laser beam instead of a needle. And instead of grooves, Philips' shiny aluminum disks have millions of microscopic "pits" that produce variations in the intensity of the laser beam's reflection as the disk spins. A photodetector translates the reflection into electrical impulses, which are then...
...during her mount, lost both her poise and rhythm and returned to her seat barely blinking back the tears after recording a disastrous score of 7.50 (out of a possible 10). Undaunted, she overcame her jitters and returned the next day to win two gold medals?in the balance-beam and floor exercises?and the roaring acclaim of the audience...
...Chrysler said in its ads that torsion-bar suspension gave extra "ease in handling." In substantiation, it submitted a "braking attitude test chart" measuring results in "inches of front suspension jounce" and the outcome of a "dynamic beam and twist" test expressed in quantities of "first mode resonance." What do these terms mean? Chrysler did not explain...
