...quantum mechanics of the '30s, formulated by Schroedinger, Heisenberg and others, made astonishingly successfuly predictions about such atoms. Physicists turned their attention from the atom to the nucleus...
...private institution, let alone university, in the United States had ever attempted a drive of this proportion before. "It was a quantum leap from anything thought of at the time," Pusey recalled last week. "With the expanding economy and the mounting operation expenditures, the costs of standing still were enormous, and this occupied me constantly," Pusey added...
Xerox, it must be noted at the outset, is a trademark of the Xerox Corp. of Stamford, Conn. The word comes from the Greek xeros, meaning "dry." It refers to the dry, electrostatic copying process (a quantum improvement over earlier wet photographic methods) finally developed in 1938 in a one-room laboratory behind a beauty parlor in Astoria, Queens, by a penurious patent attorney named Chester F. Carlson. Xerox Corp. had revenues of $4.05 billion last year, and today accounts for more than half of all photocopier sales and leases in the U.S. (The chief producers of copying machines after...
...soils. The forces to be overcome are tangible, if capricious. An industrial world is a game against fabricated nature. It is a world where man is hitched to the machine, overpowered by the size and power of the machine, yet also enlarged by the sense of the quantum jumps of energy that pulse through the industrial process. The forces are tangible, yet methodical and metrical. A post-industrial world, because it primarily involves services-doctor with patient, teacher with student, Government official with petitioner, research team with experimental designer-is largely a game between persons. In the daily experience...
British Physicist Paul A.M. Dirac attacked this dilemma in 1931 with the newly developed tool of quantum mechanics. His calculations showed that there should indeed be a magnetic particle (or family of particles) that carries a basic magnetic charge-either north or south. That charge, said Dirac, would be 68.5 times as strong as the charge on an electron. Or it would be some multiple of 68.5-say, 137. Scientists had good reason to respect Dirac's reasoning. He had earlier predicted the existence of a positron, or positively charged counterpart of the electron. The positron was subsequently discovered...
