...officials or parsons. Moderately lean students with better muscles than average often became successful scientists. Harvard-bred artists usually developed out of students with medium fleshiness and below-par muscles. The heavy but muscular students went in for the practical callings of engineering or business and generally succeeded, while lighter-bodied competitors dropped out. A few of the Harvard men sank to manual labor, but only the poorer-muscled ones stayed at that level all their lives. The better-muscled soon rose to positions where they did not depend on their muscles...
Meson Cloud. Physicists say that mesons are matter, but certainly they are matter of a very special kind. Pi mesons, whose mass is 276 times that of an electron, "live" on the average only three 100-millionths of a second. Then they change into lighter "mu mesons" (210 electron masses), which live somewhat longer, eventually decaying into ordinary electrons. The mass that mesons lose in these transformations turns principally into energy, a striking example of Einstein's principle: that mass is equivalent to energy...
...main refinery at Port Arthur, Texas, will now build a still bigger one (63,000 bbls. a day) at Gulf's Philadelphia refinery. He will also build the world's biggest (125,000 bbls. per day) atmospheric and vacuum crude-oil "topping" unit (which skims off the lighter components of crude). The result will boost the military's supply of high-octane gasoline by 42,000 gals, daily. But Swensrud also has his eye on a longer-range peacetime market: the high-compression auto engine...
Plastic Cleaners. To get around metal shortages, Lewyt Corp. this week starts production on plastic vacuum cleaners, which will be quieter, stronger, and four Ibs. lighter than present metal models...
...political scientist feels that his forthcoming duties at Harvard will be some what lighter than those he had at Yale, where he was a department chairman. Besides teaching three courses here, he will be a tutor for the first time and is, in addition, beginning work on a new book...
