...hard, impermeable, layered material that looks like black porcelain. Called Pyrographite, it proved to be five times as strong as ordinary graphite, keeps its strength at temperatures up to 6,700° F., also has the extraordinary property of conducting heat 100 times better along its main surfaces than perpendicular to them...
...around the earth for an indefinite period, moving out beyond the moon's orbit in a long ellipse and taking about 15 days to complete a full circuit. The plane of its ellipse is not the same as that of the moon's orbit but is nearly perpendicular...
...Force Base last week were digging a 15-story hole in the ground. Within weeks, the deep cylindrical pit will be paved with concrete so thick that months must pass before it cures. Then the U.S. Air Force will slide a 90-ft., 117-ton monster into its perpendicular den and seal it with heavy concrete doors against the megaton shocks of man-made thermonuclear quakes. The monster is the Titan intercontinental ballistic missile, the first weapon in Air Force history to go underground...
...people have successfully climbed to the top (15,781 ft.), and 65 have died on the way. But in all those years, mountaineers mastered only four routes to the peak itself. Attempted but never conquered was a possible fifth way, the Grand Pilastre, a 5,000-ft. perpendicular wall of gripless, smooth rock and slithery green ice that looms over empty space toward the summit. Last week the Grand Pilastre was finally conquered in a fantastic three-day climb by Italy's Walter Bonatti, 27, and Toni Gobbi, 43. Awed alpinists compared it to the first four-minute mile...
...MacDonald examined fabric shreds, wall sections, photographs, figured the directions of the four shots, compared firings from the shotgun. Two months later he presented his findings: Marion Sill had fired three times at Violet, then reloaded the gun; the fourth shot, which entered Sill's neck from a perpendicular angle, was the one that splattered his flesh on the ceiling, the one that Violet triggered from the floor. Furthermore, Expert MacDonald pointed out that the shots fired at Violet were aimed from at least 15 inches away; the gun barrel was 28 inches long. Conclusion : she could not have...
