Writing in the current issue of Science, Schmidt and Metallurgy Professor Donald Avery, both of Brown University, report that as long as 2,000 years ago, the Haya people were producing medium-carbon steel in preheated, forced-draft furnaces. A technology this sophisticated was not developed again until nearly 19 centuries later, when German-born Metallurgist Karl Wilhelm Siemens, who is generally credited with using an open-hearth furnace, produced the first high-grade carbon steel...
Nature could hardly have created anything that seems more innocuous. An invisible and odorless gas, carbon dioxide is a simple molecular linkup of just a single atom of carbon and two atoms of oxygen (CO2). It constitutes a mere fraction of the atmosphere (.03% vs. about 78% for nitrogen and 20% for oxygen) but becomes dangerous to man and other air-breathing creatures when it accumulates in concentrations higher than 10% as, say, at the bottom of deep wells or mine shafts...
...wellbeing. A key ingredient in photosynthesis-the miraculous process by which green plants grow and produce oxygen-CO2 directly or indirectly sustains all terrestrial life. Now it appears that the gas may carry the potential for trouble as well. Accumulating in the atmosphere at an accelerating rate, carbon dioxide could significantly raise global temperatures by early in the next century and dramatically alter the quality of life. With such a prospect under study, a federal official says: "We have about ten years to come up with an answer...
...Washington (Sept. 7, 9 p.m.) has Jack Albertson playing a U.S. Senator, it seems as old-hat as The Farmer's Daughter. NBC's principal new sitcom, The Waverly Wonders (Sept. 7, 8 p.m.), boasts a surprisingly ingratiating star in Joe Namath, but is otherwise a pale carbon of Welcome Back, Kotter...
