...were no cases of permanent sterility, and no diseases, including cancer, that could be attributed to the ring. In Yokohama, Dr. Atsumi Ishihama recorded a total of 19,000 women fitted with IUCDS; his choice was a ring made from a spiral of metal or plastic, and with a disk in the center suspended from three points...
Better Than Shadows. For Chief Cartographer Albert L. Nowicki of the Army Map Service, the traditional method of measuring lunar mountains by their shadows is not accurate enough. It works well only in the center of the moon's visible disk; off toward the edges it fades into uselessness. So the Army has turned to stereo photo-mapping in order to take advantage of the fact that the moon wobbles slightly but predictably at intervals of 3½ to seven years as it orbits the earth. This means that pictures taken of the moon at different times are like...
...deduce lunar elevations from slight differences in matched pairs of photographs. Only a few years ago the job would have taken too long to be practical, but the Army's Honeywell computer raced headlong through thousands of bristling equations. Gradually the map of the moon's visible disk, which has just about the same area as North America, filled with measured mountains and crater rims...
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...
...sculptural shapes dominate Collie's show at Manhattan's Nordness Gallery. One is a tilted disk that looks like a model of a flying saucer. Such disks jiggle at a fingertip touch, but may weigh as much as 13 Ibs.-as a thief discovered when he tried to whisk one away from the Chrysler Art Museum, only to have it drop with a clang. The second, also a space-age motif, resembles the hollow cone of a missile. Inside, visible from both ends, are two metallic spheres, one hanging down like a tiny bathysphere on its nylon thread...
