...Uranus and Neptune. Scientists are even speculating that by carefully following Pioneer's movements they may detect effects of long-sought gravity waves. Postulated by Einstein's general theory of relativity, these waves are thought to be the carrier of the gravitational force, just as the photon, or light particle, is the transmitter of the electromagnetic force...
...helmsmen were Sulu (George Takei), the Asian sword-fighter responsible for firing phasers and photon torpedos and wiping people off the face of the galaxy and Ensign Pavel Chekov (Walter Koenig), the young Russian hipnik who drank "wodka inwented by a little old lady from Leningrad" and fell in love every three episodes. Finally, chief nurse Christine Chapel (Majel Barrett Roddenberry) drooled over Spock...
...somewhere among the stars he is studying. The library where he ponders has no formal checkout desk. No librarians remind borrowers to fill out checkout slips, which simply admonish borrowers to return books as soon as they can. Casual discussions in various offices around the Center concern satellite launching, photon sorting, and ways of measuring gravity waves. A bumper sticker on one office door says cryptically, "Black holes are out of sight," while a door in the basement carries the impressive label "Cosmic Dust, Meteorite, and Lunar Studies Lab." In another basement lab two scientists tinker with an elaborate device...
Here a short digression is necessary. Modern quantum mechanics describes the forces between particles in terms of other, "mediating" particles. The mediating particle of gravity is called the graviton. The mediating particle of the electromagnetic force is called the photon. And the mediating particle of the "strong" force, proposed in 1934 by the Japanese physicist Hideki Yukawa, is called the "pion...
...this inexpensive phototypesetting process, character images on a film strip are projected directly onto photographic paper that is then converted into a printing plate. Garth, now 59, first worked on the process in the 1950s, when he was president of Photon, Inc. After a corporate squabble, he left the firm in 1960, took his chief engineer with him, and set up Compugraphic. His first successful product was a computer designed to cut 50% off the time required to set a telephone book in type; Garth introduced it by driving it round the country in the back of his station wagon...
