...Rome 34 years ago, studied at the University of Pisa, has taught and researched at the University of Rome since 1927. Short, wiry, dapper, cheerful, he is married, has a 5-year-old daughter, likes to ski, play tennis. Some years ago he perceived that when a nuclear impact knocks a neutron and a positron out of an electron, there is a mysterious disappearance of energy. He surmised that the excess energy rode away on a little particle which, now generally accepted as theoretically necessary, still eludes observation. It is because of Fermi that this little particle, the neutrino...
Wolfe's first cinema assignment is to discover who, by means of a gun concealed in a golf club, with a trigger released by impact with the ball, killed jolly old Professor Barstow and why. By the time he succeeds, the picture has unraveled the grim and interwoven biographies of an irascible golf professional, an Argentine olive oil dealer, a lady idol worshipper and a young man with an Oedipus complex. It has also indicated that its hero, less dashing than Philo Vance and less whimsical than Charlie Chan, but more mercenary than either, will be a highly acceptable...
Metallic Energy. To establish the strength of a metal engineers squeeze or pull (static tests) or hit (impact test) a sample piece until it breaks. Though one test is as good as another, none really explains why an automobile bolt occasionally cracks, an airplane strut snaps, a battleship's armor plate yields. By building a machine which hits a piece of metal with the whack of a bullet traveling 1,000 ft. per sec., H. C. Mann of Watertown (Mass.) Arsenal discovered that when a piece of metal is struck a very strong blow, its molecules release some...
...strange yelping sound punctuated the din of the machine. Anthony opened his eyes again and was in time to see a dark shape rushing down towards him. He uttered a cry, made a quick and automatic movement to shield his face. With a violent but dull and muddy impact, the thing struck the flat roof a yard or two from where they were lying." Helen went back to her husband and Anthony was left alone with his thoughts...
...carousel in the rain should be struck by more drops in front than in back. This small daily variation in the cosmic rays has actually been observed, so Dr. Compton agrees they must come from the remotest depths of space. What is their scientific importance? 1) A cosmic ray impact led to the discovery of the positive electron, a fundamental particle of matter. 2) The geographic distribution of the rays facilitates study of Earth's magnetic field. 3) For laboratory work cosmic rays provide atomic bullets thousands of times more powerful than any produced by man. 4) Their behavior...
