Hall began to doubt the cloud theory when he watched squids discharging their ink. It does not form a cloud for a considerable time, but hangs together as a dark, viscous mass. To learn more, Hall experimented with a small captive squid in a light-colored wooden tub. When his hand approached it, the squid changed color rapidly, as squids do. Just before Hall grabbed for it, it turned dark-and Hall found himself squidless. He had grabbed a blob of ink-darkened water. The real squid, now light-colored, was safe at the far side...
Raytheon's airway radars, which have revolving antennas 40 ft. wide, are modeled after equipment used in military air-warning networks. Raytheon engineers are confident that they can track large commercial airliners, flying 70,000 ft. up, 200 miles away. When rain clouds cut off the view of a distant airliner, the radar can switch to a special "circularly polarized" wave that is reflected differently by spherical raindrops and the metal surfaces of wings and fuselage. This gimmick makes an airliner visible even behind a rain cloud. Another gimmick makes the radar blind to all objects that...
...atomic oxygen, but since the supply is renewed every day by sunlight, it should be inexhaustible. This opens up some interesting possibilities. In an earlier experiment the Cambridge men discovered that when nitric oxide is re leased in daytime, it is acted upon by sunlight and forms a dense cloud of electrified particles that reflect radio waves as a mirror reflects light. A few such reflectors properly spaced around the curve of the earth might support new kinds of long-range communication. Rockets fired at night might illuminate large areas if they released substantial amounts of nitric oxide...
...appropriately lazy cloud of smoke circled the room. It wasn't a large room, and so it was crowded, in a disorganized way. Most of the smoke rose from clusters around the three chess boards; most of the conversation seemed to come from a corner where two students were besieged by a crowd of eager gestures...
...Mississippi state legislature. With his father's backing, 24-year-old Jim Eastland had no trouble in getting elected, and for four years he was one of then Governor Theodore Bilbo's leading supporters in the house of representatives. In 1932, when Bilbo left office under a cloud of financial troubles, Eastland also got out of politics and began to practice law. The same year he married attractive Elizabeth Coleman, daughter of a Delta doctor. Says Libby: "We got engaged in a swing on the front porch, naturally. How else is it done in the South...
