...fourteen hundred 4-H Club members relieved their mothers of that wintered-in, cabin-fever feeling by piling outside and scurrying to register for their summer activities. Bud Hilton's Thawing Service advertised steam-cleaning service for building exteriors, while out on the Alcan Highway, dust warnings replaced ice-warning signs. On the Fairbanks outskirts moose calves, abandoned by their mothers, bawled like babies, and into a downtown pool hall waddled a full-grown porcupine. It was 80° in the Panhandle's Ketchikan, and 60-lb. salmon flopped through the water in search of fishermen. Farther...
Opening more graduate conference courses to those qualified--whether juniors or sixth year GSAS students--can help alleviate two stereotyped situations. First, the bored upperclassman, cutting lectures in his survey courses, tossing off papers the night before for an easy B; the other, the dry-as-dust graduate whose vision is narrowing to the confines of his special field. CEP changes in tutorial and course requirements allow the undergraduate more flexibility. Revisions in the Ph.D. program are directing the time of senior faculty members to graduate tutorial work. For the high-ranking student who feels his middle-group courses expendable...
...Maurice Dubin of the Air Force Cambridge Research Center told about the experiences of the Army's satellite Explorer I, which carries two meteorite detectors. One of them, a microphone that picks up the slight vibrations in the satellite's shell that are caused by the smallest dust particles, registered only seven hits during the 120 minutes that the transmitter could be heard. The other detector, a set of delicate coils designed to be damaged electrically by meteorites at least 10 microns (1/2500 in.) in diameter, showed no more than one hit (possibly none) in 32 days...
...moon can be given comparative ages by the way they overlap, and that the walls of the oldest ones are generally low. This means, said Gold, that during the 4 billion years or so of the moon's life, its exposed rock has been slowly turned into dust by bombardment of rays and particles from the sun and space. The dust, kept stirred up by the same agents that formed it, has flowed like a slow liquid into the moon's low places. So the maria, said Gold, are not filled with lava, but with dust, perhaps several...
...Astronomer Fred Whipple of Harvard thinks that although the moon may have plenty of dust, its surface has been solidified. There may be a thin layer "like dust on a grand piano," but the underlying material, cemented together (not stirred up) by bombardment from space, is probably "crunchy" and strong enough to support an alighting spaceship...
