...Merle F. Walker and Robert Hardie, at the Lowell Observatory, Flagstaff, Ariz., measured Pluto's light with photoelectric apparatus. They found that it varied slightly in brightness and that the variations repeated themselves regularly, as if dark markings were passing across Pluto's disk. The period turned out to be 6.390 earth days, so Walker and Hardie concluded that this is the length of Pluto...
...much smaller ones do; their purpose is to gather more light, making dim stars and nebulae bright enough to affect a photographic plate. Much the same result can be accomplished by amplifying dim light instead of gathering more of it. Dr. Albert G. Wilson, director of Lowell Observatory, Flagstaff, Ariz., believes that a 40-in. telescope equipped with a Lumicon will equal a 240-in. telescope in luminescence. The 200-in. Hale telescope on Palomar Mountain, the world's biggest, can be made to equal a 1,200-incher...
...turns out the fierce, intelligent Falcons, the Air Force's air-to-air missiles. The Falcon's tiny gyros, bearings and electronic components must be manufactured with a super-watchmaker's precision. The job is done in a great, windowless factory on the desert outside Tucson, Ariz. No speck of dust can be tolerated. The air is changed by fans and filters every nine minutes, and positive air pressure is maintained inside the building so that any air leakage will be outward, not inward. Engineers in the drafting rooms are forbidden to tear paper or use pencil...
...other nine are in Logan, Utah; Cardston, Alta., Canada; St. George, Utah; Manti, Utah; Mesa, Ariz.; Honolulu; Salt Lake City; Idaho Falls, Idaho; Bern, Switzerland. † Who told Founder Joseph Smith in Manchester, N.Y. Sept. 21, 1823 about the golden tablets that held the fundamental tenets of Mormonism...
When San Manuel hits full production, perhaps by midsummer, it will process 30,000 tons of ore daily and yield 70,000 tons of copper yearly, plus 3.000 tons of molybdenum as a byproduct. Thus Magma, which has only one other smelter (at Superior, Ariz.), will boost its total copper production to almost 100,000 tons yearly, jump from sixth to third place among U.S. producers (after Kennecott and Phelps Dodge). At peak production San Manuel will expand U.S. copper output by 8%, molybdenum...
