Several campy collections of old TV and movie material are fun as well. ( Rhino's Sleazemania series contains howlingly bad excerpts from old antidrug shorts, soft-core porno and previews for grade-Z melodramas ("Terrifying realism! Claws at your unbelieving mind!"). The Video Doll Shoppe, from the New York City-based Video Resources, is a compilation of doll commercials from the 1950s and '60s, including a gloriously dopey promotional film from the Ideal Toy Corp. describing the invention and manufacture of Betsy Wetsy...
...apples. Conversely, it would seem that an apple tree is a work of art, a rhapsody in green and white. And it grows -- this is the miracle -- from a little brown seed no more than half an inch long, of which there are half a dozen inside every apple core that you throw into the garbage pail...
...software is reported to be controlled by a powerful, versatile operating system called Mach, a variation on AT&T's popular Unix system. (In addition to its other virtues, Mach is designed to allow computers that have been hooked together to share seamlessly one another's processing power.) The core of Jobs' computer is the Motorola 68030, the most advanced general- purpose microprocessor chip on the market. That device's prodigious capabilities have been further enhanced by an array of custom-made chips that are not only state of the art but also artfully laid out. Microsoft Chairman Bill Gates...
...well as its unexplained reversals. About once every million years, magnetic north and south inexplicably exchange places. Scientists do not understand whether this phenomenon comes about gradually, say, over thousands of years, or all at once. One idea, advanced in recent years, is that turbulent eddies within the core-mantle boundary somehow give rise to electromagnetic disturbances that trigger the reversals. A rain of iron particles, say some scientists, might supply the energy to keep the eddies churning...
...drama of the recent discoveries, scientists still have a very tenuous understanding of the structure and dynamics of the core. Nonetheless, other areas of geology have advanced enough to give scientists a reasonably consistent idea of how the overall picture fits together. Says Subir Banerjee, a geophysicist at the University of Minnesota: "In every discipline, our measuring capabilities have gone up so much that we are at last able to home in on the earth's core by a number of techniques." For scientists who have long struggled to penetrate the mysteries at the center of the earth, solving...
