...from John Jacob Astor, William Jennings Bryan, Thorstein Veblen, Lincoln Steffens or Henry George. The answer is Henry George, and research showed that more than half the students in the top one-fifth of those taking the test got it right, compared with only 8% of those in the bottom one-fifth...
Arbitrary Altitude. The moon has no sea level to use as base elevation (its so-called seas are waterless plains), so Nowicki selected Mösting A, an easily identified crater near the center of the disk and gave the bottom of its crater the arbitrary altitude of 7,000 meters (23,000 ft.) to serve as reference for all other elevations. The finished map, which is 4.5 ft. in diameter, includes more than 5,000 surface features, giving elevations in hundreds of meters. One version of the map shows high and low areas in colors: the highest mountains...
After years of patient probing, oceanographers still have only the sketchiest notions about the shape of the drowned, undersea landscape that makes up 70% of the earth's crust. They know even less about undersea "weather"-the currents, eddies and swift temperature changes that sweep across the ocean bottom like winds and storms on land. Not until Columbia University's Hudson Laboratories announced the first direct measurements of deep waves, could oceanographers be sure that the great, lazy surges actually exist...
...deep-down waves are vertical fluctuations similar to surface waves, but instead of rolling across the sharp interface between wind and water, they travel in transitional zones between water layers of different density. No one knows what causes them. It may be the turbulence of bottom currents flow ing over ridges and valleys of the sea bed; there may be a connection with the rotation of the earth. Some of Dr. Pochapsky's buoys rose and fell 100 ft. twice a day, although the surface far above them moved very little with the tides...
...Woody Woodbury struggle to get a foothold in the slippery story about a rich campus cutup and a poor coed. But the standout performer is a bearded beachnik called Kelp. He paints a small face on his chin, upside down. Then he covers himself with sand, leaving the bottom half of his face exposed, and spiels gags. The gags aren't funny, but in a movie like this the audience can readily identify with a man who buries his head in the sand...
