Because the moon rotates on its axis only about one-thirtieth as fast as the earth, stars move slowly across the lunar skies, making it easier to track and photograph them. Because lunar gravity is only one-sixth the earth's, structural distortions caused by the sheer weight of large telescope mirrors and their supports will be dramatically lessened. Some scientists have estimated that telescope mirrors as large as 2,000 in. in diameter (ten times the earth's largest) could be used effectively on the moon...
Beer cans, eggs, paint, soda bottles, chunks of concrete, and pieces of steel showered from Manhattan skyscrapers. One girl was struck on the head by a bottle of paint dropped from a thirtieth floor window. The paint splattered fifty feet and the girl was taken to a hospital unconscious...
...Paolo Franzini had in mind when he went to work with Brookhaven's synchrotron in January 1965. Along with his wife, Dr. Juliet Lee-Franzini, Drs. Charles Baltay and Lawrence Kirsch, he fired particles called pi mesons into a bubble chamber filled with liquid deuterium. About one-thirtieth of the times that a pi meson hit a deuterium nucleus, out came the eta meson, which decays into three pions. The pions streaked through the bubble chamber, the positive leaving a line that curved to the right, the negative peeling off to the left, and the neutral leaving no path...
Frantz has lived in an attic for thirteen years--fooling himself into believing that Germany is being destroyed, throwing empty oyster shells at a picture of Hitler, and making tape recordings for the "crabs" who will judge mankind in the thirtieth century. He sees no one, and refuses an interview with his father, whom he associates with the family's Nazi background. Even time is kept out of his attic world. The only one who can see him is Leni, his sister, who brings him his meals and loves him incestuously. To keep Frantz for herself, Leni refuses to tell...
...committee declared in the "West helmer Report" that research in chemistry is severely under-supported. The financial support per Ph.D. graduate in chemistry ranges from one-fifth to one-thirtieth the support per Ph.D. in astronomy, physics, and the earth sciences, the report said, and as a result many worthwhile projects are not even attempted...
