Davis acknowledges that his terrifying scenarios are based on a large quotient of guesswork. Meteorologists may not ever achieve enough mastery over hurricanes to affect the earth's heat balance. Still, the warning echoes a theme that is finding widening support among thoughtful scientists: man must learn much more about nature's most elemental forces before he tampers with them...
...also suggests that rational science may be limited in its ability to comprehend nature; at best it can only arrive at certain statistical probabilities in determining, say, where an electron is at any given moment. the concept that the universe cannot be known by more definite methods that such "guesswork" was so revolutionary that even Einstein could no accept it. " God does not play dice with the universe," he insisted...
...tries to correct malformations in a child's teeth and jaw, he must attempt to figure out how these parts will change as the youngster matures. Dr. Geoffrey Walker of the University of Michigan School of Dentistry has come up with a method that promises to reduce the guesswork involved in this process. He has taken 15,000 skull-profile X rays made over a period of years and converted these pictures to coordinate maps of the skull and jaw. The result is a computer model capable of predicting how a jaw will grow. With just a single...
...Nixon Adviser Alan Greenspan adds that he expects the rate to range between 41% to 51% for several years. The Government's traditional "full employment" target is 4%; the irreducible jobless rate, composed of people moving between jobs and those only marginally employable, is a matter of guesswork. The mid-point of the experts' guesses is a shade more than...
...when-could this extraordinary event have occurred? Using both hard information and informed guesswork, Perrin and his associates evolved an imaginative but logical hypothesis. The scientists knew that the concentration of U-235 found in contemporary uranium deposits is too low to sustain a chain reaction. But they were also aware that radioactive U-235 decays at a known rate, and that 1.7 billion years ago-the approximate age of the Oklo deposit -U-235 made up 3% of raw uranium deposits. This is roughly the same concentration that is created in artificially enriched uranium fuels and thus is enough...
