摘要:
A summary is given of Doppler's life and career. He was born 180 years ago on November 29, 1803, in Salzburg, Austria. He died on March 17, 1853 in Venice. The effect bearing his name was first announced in a presentation before the Royal Bohemian Society of the Sciences in Prague on May 25, 1842. Doppler considered his work a generalization of the aberration theorem as discovered by Bradley. With it came the inference that the perception of physical phenomena can change with the state of motion of the observer. Acceptance of the principle was not without controversy. In 1852, the mathematician Petzval claimed that no useful scientific deductions can be made from Doppler's elementary equations. In 1860, Ernst Mach resolved the misunderstanding that clouded this controversy. The Doppler effect is alive and well. Its role in radio science and related disciplines is enumerated.

摘要:
The latest in a series of National Oceanic and Atmospheric Administration (NOAA) meteorological satellites is scheduled for launch from Vandenberg Air Force Base, Calif., on December 1, 1984. High surface winds delayed the launch from the originally scheduled date of November 8. The 1712‐kg satellite, the NOAA‐F, is to be launched to an altitude of approximately 870 km into a circular near‐polar orbit. The satellite is the sixth in the current series of 11 NOAA satellites that collect meteorological readings and transmit the data to ground stations for local weather analysis and foreca
