Elsewhere around the world, other scientists are examining fossils, stone tools, soil and rock samples, and even pollen grains in an effort to find more of the missing pieces in the puzzle of man's ascent. They are motivated not only by curiosity and dedication to their science but also by the knowledge that what they discover may help man to understand himself. Says Leak ey in his just-published Origins (Dutton; $17.95): "By searching our long-buried past for an understanding of what we are, we may discover some insight into our future...
...days, by donkey and camel. The discomforts may be worth it; a geological survey of the area shows fossil-bearing sediments between 5 million and 9 million years old, laid down in a period that has so far yielded few clues about the ascent...
...made the ascent? "It was a personal challenge," he said, "a challenge to my ingenuity." The trade building, Willig said, "was very appealing. Very vertical." Confronted by his talent, temperament and instant popularity, New York City soon surrendered and canceled the $250,000 suit. Instead, said Mayor Abraham Beame, the city would settle for a fine of $1.10-a penny for every floor...
...first steps on that ascent was the realization that the conditions of temperature and density necessary for the sustained fusion of ordinary hydrogen nuclei were far beyond the present capabilities of science. But experiments showed that it was easier to fuse two isotopes, or different forms, of hydrogen: deuterium and tritium. Reason: the nuclei of these isotopes have larger cross sections than those of ordinary hydrogen nuclei. Thus the probability of direct collisions between them is increased and that in turn means that less extreme conditions are required to make them fuse. The easiest fusion to attain, scientists determined...
...book grows from a television series Galbraith filmed for the BBC along the lines of J. Bronowski's Ascent of Man. In the series, Galbraith jaunts around the world to various spots of particular import in his study, strolling along the countryside of Marx's youth and surveying the barren wastes of Death Valley (which he offers as an example of the New York-Philadelphia corridor after World War III). As a substitute--a good one--for the varied film clips that bring his series to life, The Age of Uncertainty is studded with more than a hundred photographs...
