DIED. FRED WHIPPLE, 97, inventor and rocket scientist whose "dirty snowball" theory made it easier to track comets; in Cambridge, Mass. Whipple correctly proposed that the core of a comet consists of ice, ammonia, methane and carbon dioxide, and that its tail is formed by particles that break off from the mass as it approaches the sun. Over seven decades at Harvard University and the Smithsonian Astrophysical Observatory, Whipple also discovered that the source of meteors is not far-flung stars but Earth's solar system. Anticipating space flight, he invented in 1946 a thin outer skin of metal known...
...WHIPPLE, 97, rocket scientist whose "dirty snowball" theory made it easier to track comets; in Cambridge, Massachusetts. Before Whipple explained the phenomenon in 1950, astronomers thought comets were loose collections of dust and vapor held together by gravity. Whipple argued that the core of a comet consists of ice, ammonia, methane and carbon dioxide, and that its gossamer tail consists of particles that break off from the mass as it approaches the Sun. Over seven decades of work at Harvard University and the Smithsonian Astrophysical Observatory, Whipple also discovered that meteors do not come from far-flung stars...
Remember when ammonia and pine-sol were the telltale scents of cleanliness? Times have changed. A growing number of consumers are following their noses to a new and pricey category of housekeeping products that combine cleaning power with aromatherapy. Wendt, for instance, is partial to the Mrs. Meyer's brand of dish liquids and countertop sprays. "The smell is amazing," she gushes, "and it fills the house for a little while when you use it." She's also fond of Laundry Fragrance--added in the final rinse cycle--from the Good Home Co., which comes in lavender, vanilla and such...
...high temperatures this summer could produce spikes in prices and regional brownouts. In June natural gas sold for an average of $5.83 per 1 million BTUs, up 169% from the same week in 1998. Higher prices already are taking their toll on energy-dependent industries, like those that produce ammonia, the key ingredient in fertilizer. In June 1998 the Louisiana Ammonia Producers trade association had nine corporate members with 3,500 employees. Today it has one, CF Industries. "We've lost 2,000 employees," says Jim Harris, a spokesman for the producers, who accounted for 40% of America's ammonia...
...door or step on something," says Lieut. Colonel Ivo Musil, chief of operations for around 390 Kuwait-based Czech soldiers, part of a "consequence-management team" tasked with detecting and cleaning up after a chemical or biological assault. The vapors of many industrial chemicals - including phosgene, chlorine and simple ammonia - can burn, corrode equipment or even kill. Here's the scary part: detection of such chemicals will be next to impossible, even for the Czechs. The small tabs of test paper that G.I.'s carry will not pick them up either. U.S. soldiers in Kuwait's northern desert are training...
