...separate patterns of Venusian light on an interferometer-a device that splits a beam of light, sends each half along a path of different length, and then rejoins them in an interference pattern of light and dark fringes. Computer analysis and averaging of these patterns by scientists at Block Associates in Cambridge, Mass., produced two of the clearest spectrograms ever obtained of Venus at high altitude. Although the spectrograms conclusively proved that there were no ice crystals in the Venusian atmosphere, they did reveal what appeared to be a significant trace of water vapor. But Kuiper and his associates were...
...portion of the earth's atmosphere still above them, the airborne astronomers had also taken about 1,000 interferograms of the moon, which was close to Venus in the sky during the flight. Although the moon is known to be dry, the lunar spectrograms produced by the Block computers also showed evidence of a trace of water vapor. The vapor, the scientists knew, had been detected not on the moon but in the earth's atmosphere. Thus, by eliminating the same proportion of terrestrial vapor from the Venus spectrograms, they were able to determine the true amount...
...after a bitter "management dispute" in December 1965. Pentron had lost $2,400,000 that year, but Andreas, according to the charges, was determined to unload his 12% shareholding at "as high a price as possible." Ness, Rolland, Furla and Kozak promised to sell a 144,000-share block of Andreas' stock at $3 or better, if Andreas would in turn sell them another 175,000, which he held in a trust for his children, at $2 a share...
World Stake. "There are practical, economic and political problems to be resolved," says I.M.C. President Nelson C. White. But no such problems are likely to block the vast effort. Though a European partner has yet to be found, Madrid and I.M.C. are not worried about raising the $160 million needed as an initial investment. The long-term investment to bring production up from 3,000,000 tons of phosphate in 1970 to 10 to 12 million tons by 1976 could go as high as half a billion dollars. By that time the Sahara phosphate venture should be a going operation...
...Portuguese, Greeks, French, Canadians, Jews, Irish, and Italians, many of whom are in the low and moderate income group. Many families have lived in their homes for many years. Their lives are built in significant ways on their relationships with relatives and friends living nearby, often on the same block, even in the same multiunit house, with churches and clergymen in the neighborhood, with schools and teachers, and with shopkeepers whom they know and trust and with whom they like to trade and talk...
