...test being conducted by the National Oceanic and Atmospheric Administration (NOAA), was to prevent the buildup of electrical potential during a storm, and thus to prevent the occurrence of damaging lightning. Like iron filings near a bar magnet, the 4-in.-long, hair-thin fibers, when released in a thunderhead, align themselves with the lines of force in the electrical field of the cloud. What is more, negative and positive charges build up at opposite ends of the fibers, creating miniature electrical fields and ionizing the air around them. The ionization increases the conductivity of air within the thunderhead...
...pictures are solemn brown studies. Here and there, light flashes within them like electricity inside a summer thunderhead. At first glance, they are quiet paintings of commonplace subjects-familiar faces, weather-beaten buckets, battered stone walls and boulders - with none of the candy-colored savor of pop culture or the treacle of lap dogs and firesides. Basically, An drew Wyeth paints his own backyard...
More than any of his contemporaries, Still believes art is an exertion of man's freedom against a hostile world, a machete in the jungle. Such a tool is his latest work shown, 1963-A, bristling with black fury like a thunderhead. It is swathed onto raw canvas with his palette knife like sooty icing, with only flecks of lavender and blue to serve a lighter side. It is also a darkling mirror of Still's personality. As he says, "Painting must be an extension of the man, of his blood, a confrontation with himself. Only thus...
RAYMOND PARKER-Kootz, 655 Madison Ave. at 60th St. A thunderhead of hard-edged clouds in shocking colors, Parker's shapes-in-space seem waiting to collide, never quite make a satisfactory bump. Through...
...formation of rain. Vonnegut suspects that the lightning creates vast numbers of charged particles that cause a cloud's small water droplets to attract one another and swell into drops large enough to fall as rain. If he can learn how to make lightning flash in a growing thunderhead, he may yet learn to coax rain from a cloud that would otherwise soar unproductively overhead...
