Ever since Charles passed 30, an age that he once said would be a good time to marry, speculation has intensified. Britons, obviously, are curious to know who will be their future Queen; they are also concerned that the Prince produce a royal heir. The field is narrowing as eligible girls are married off. Religion also poses a problem in Britain. A constitutional change would be needed before Charles could marry a Catholic, like Princess Marie-Astrid of Luxembourg. The Princess has repeatedly been mentioned as a possible royal match, but quite apart from the religious bar, the two barely...
Columnist Joseph Kraft studies the Democratic field, staring at the political teeth, smacking the ideological haunches. Max Lerner agrees with many commentators, including the Chicago Tribune's Michael Kilian, that the Reagan landslide has "all but wiped out Ted's strategic position." The Christian Science Monitor's Godfrey Sperling demurs: "[Edward Kennedy] seems well positioned to become the de facto head of the party-and to be its 1984 presidential candidate." Meantime, New York magazine's Michael Kramer knocks out the Republican early form: "Where is Kemp today? He is a front runner...
...barrel. When the gun is fired, a powerful pulse of electricity goes down one rail. As the current surges to the other rail, it vaporizes a metallic fuse in back of the bullet, creating a cloud of electrically charged particles, or plasma. Simultaneously, it generates a strong magnetic field between the rails, like those in an electric motor. The field exerts a force against the plasma, just as it would against a motor's rotor. But instead of spinning, the plasma moves forward, guided by the rails and pushing the projectile ahead of it. Not constrained by any sonic...
...uses two rapidly spinning flywheels to build up and store electricity. In bare ly a second the Canberra homopolar de livered as many as 500 megajoules of direct current - enough to light up a small city. Such a quick surge is essential for rapid buildup of the propelling magnetic field. Eventually, they were able to deliver the electromagnetic kick even quicker, and accelerated small plastic cubes to muzzle velocities of 6 km per second...
...University of California's Los Alamos Scientific Laboratory and at the Lawrence Livermore Laboratory, scientists added another improvement: a magnetic flux compression generator, which increases the thrust of the magnetic field by squeezing it with a carefully directed explosive charge, a technology pioneered during nuclear weaponry research. When the gun is fired, the electric surge ignites the near end of an explosive strip placed just on the outside of one of the rails. As the detonation speeds forward, faster than the blink of an eye, it presses one rail against the other, confining the magnetic field between them...
