...most important signal, they said, was a change in the velocity of vibrations that pass through the earth's crust as a result of such disturbances as quakes, mining blasts or underground nuclear tests. Earth scientists have long known that tremors spread outward in two different types of seismic waves. P waves cause any rock in their path to compress and then expand in the same direction as the waves are traveling. S waves move the rock in a direction that is perpendicular to their path. Because P waves travel faster than S waves, they reach seismographs first...
...take these nuclear risks, the scientists advised the Federal Government to: 1) start a strict energy conservation program; 2) develop nonpolluting ways of mining and burning coal; and 3) work toward using "the energy from the sun, the winds, the tides and the heat in the earth's crust." All this is familiar stuff, but the large number of concerned scientists-about 20% of those whose signatures were solicited-may lend new weight to the recommendations...
...Lion has a view of the glories of combat and courage that is both willful and wistful. All enemies are united in a common bond of honor. Blood shed is never ignoble, always ennobling, and adversaries fight with grace and mutual respect. The movie even has enough bluff and crust to look, at least superficially, like a real military romance, even a plea for manifest destiny. These notions are not being advanced as political theory but as the sort of antique sentiments that keep the movie true to its storybook sources. The glory, Milius knows, was mostly a dream...
...camp and are likely to keep doing so. Benton's revival has less to do with his art than with the grass-roots Americana he celebrated, which has gone forever. Besides, they don't make them like Thomas Hart Benton any more, not with that salt and crust and feistiness and scrappy bouncing bigotry. It is not much solace to reflect that we still have plenty of artists whose work, though in a different way, is just as rhetorical and simple-minded...
...provided the theoretical basis for things like submarine geology and attempts to study the underwater mountain range that bisects the Atlantic. Nor does he slight the host of others who have mapped the ocean bottoms, peered into smoking volcanoes or attempted to drill through the earth's crust to the semimolten mantle that surrounds its liquid core. Along the way, Sullivan scatters suggestive pieces of evidence with a skill that would do credit to Agatha Christie. He points out that the ancestors of certain North American animals seem to have come to their new home from Asia, something they...
