...view of America as an experiment remains a tremendously exciting fact. It sets up an important parallel between conservatives and radicals. The radicals would sneer at the "American Proposition," the belief that the U.S. must live up to a special act of providence, which was John Courtney Murray's scholarly elaboration of "God's country." And yet this fierce sense of a special American destiny is where Murray -and Henry R. Luce-meet the radicals. Radicals make demands on America that could only be fulfilled by an extraordinary nation, by a nation straining against the limits of history...
Easier said than done. First, Chemist Jones tested the common theory that the bicycle's front wheel acts like a stabilizing gyroscope. He attached a second front wheel, parallel to the first that did not quite touch the ground. It could thus be spun in the opposite direction of the standard wheel, canceling out the gyroscopic effect. Jones optimistically named his creation URB I (for Unridable Bicycle 1). But surprisingly enough it proved to be easily ridable...
...reflector depends on the help of 63 smaller mirrors set in eight rows on a terraced slope in front of it. Called heliostats (from the Greek helios, sun; statos, to cause to stand still), they track the solar disk across the sky, capture its light and bounce it in parallel beams into the big mirror. The system involves some ingenious engineering. Each heliostat is controlled by its own photoelectric cells. Whenever one of the hehostats (each of which is made 180 individual mirrors) loses its lock on the sun, these tiny electric eyes inform a minicomputer, which in turn controls...
...first of several unmanned space probes is scheduled to pass close to Jupiter, which apparently has a methane and ammonia atmosphere much like the one that one shrouded the earth. Data from the missions may confirm that the processes now under way in Jupiter's atmosphere parallel those that occurred on earth bil lions of years...
...Manhattan, says Wolff, cooperate with fellow walkers. They might not exchange pleasantries like their small-town counterparts, but they "do take into account the qualities and predicaments of other pedestrians in regulating their own behavior." For instance, they generally follow certain unwritten rules of sidewalk traffic. Some of these parallel the written laws of the road; some simply reflect good old-fashioned chivalry...
