...road is dusty, winding and tortuous, but every Wednesday and Sunday several hundred people turn off the smooth concrete of Route 142 near Anaheim, Calif., and bump their way upward to the oak-studded hills of Carbon Canyon. They assemble themselves on folding chairs formed in a semicircle in a glade near the top of the Hill of Hope, and there await the Miracle of St. Joseph. They are never disappointed. At 10:30 a.m., a stocky woman with soft gray hair and intense brown eyes walks quietly in front of a modest pedestal holding a small statue...
...dating technique was conceived by Chemist Jeffrey Bada of the Scripps Institution of Oceanography while he was trying to date some fossil-laden sediment from the ocean floor. The standard method for determining the age of fossils is the so-called carbon 14 clock, which is based on the ratio of ordinary carbon atoms to atoms of the radioactive isotope carbon 14 found in the specimen. The carbon 14 atoms decay at a known rate and are not replenished after the creature dies; thus the proportion of ordinary carbon to carbon 14 slowly increases. But the carbon clock only works...
Catalyst. Chemically, platinum is capable of changing certain noxious gases, including smog-producing hydrocarbons, into harmless carbon dioxide and water vapor. A platinum-coated honeycombed structure called a catalytic converter has so far performed best in meeting the tough federal emissions standards for '75 and '76 model cars. According to top auto executives, the amount of platinum needed for each car is one-tenth of an ounce. Thus, with total U.S. new-car sales expected to top 10 million units annually for the foreseeable future, manufacturers will need more than a million ounces of platinum a year...
...flight, he talked further to TIME'S Austin. He differed with McGovern on some issues, and he wondered "just how far the Vice President can disagree in public with the President." He thought, on the other hand, the public might like a Veep who "is not a carbon copy of the President." Was he irked at being McGovern's fifth choice this week? "No, I'm not egotistical enough to think I'm the only option open to George McGovern...
Because it is the second planet from the sun, Venus is exposed to about twice as much solar radiation as the earth. But this proximity alone does not account for the high Venusian temperature. While its carbon-dioxide atmosphere lets in the sun's radiation, it also keeps in the heat (infrared rays) given off from the planet's surface, thus creating a "greenhouse effect." Furthermore, as the temperature rises, more carbon dioxide is boiled into the atmosphere, only to increase the effect...
