Molecular Beam. Stern and Rabi tackled the question: what holds the nucleus of an atom together? Its protons have positive charges which repel each other, yet the nucleus as a whole possesses a magnetic force that keeps them from breaking loose. Nuclear magnets are so small that for a long time no one knew how to measure them. But at Hamburg, where Rabi worked with Stern as a graduate student, Stern discovered...
...developed a "molecular beam" consisting of a stream of molecules shot through a very fine slit into a vacuum tube. In the empty tube, each molecule traveled in a straight line. When it was subjected to a magnetic field, a molecule's magnetic "moment" or force could be gauged by the extent of its deflection from a straight course...
There is another reason for this X-ray tube's phenomenal performance: it uses a "magnetic lens," similar to that in the electron microscope (TIME, Dec. 14, 1942), to focus the electron beam in the tube on a bull's-eye only .01 inch in diameter, instead of the usual quarter-inch focal spot. Thus the X rays emerge in a sharp beam and produce well-defined shadows even after passage through thick steel...
...delinquency are crudely underlined and reiterated; some of the delinquent episodes are dragged in by the hair. It will remain a mystery forever, for instance, just how or why Miss Granville gets killed in a roadhouse brawl. But a memorable amount of adolescent confusion and pain flickers on& off-beam, illuminating its causes with an honesty, economy and poignancy which are rare on the U.S. screen...
Janie's father (Edward Arnold), who publishes the town paper, writes a blast about youth's pitfalls, but while his wife (Ann Harding) and his best friend (Robert Benchley) demur, the mote in his own eye grows to beam size. Janie, one night when the family is out, arranges to vibrate with Pvt. Lawrence in the privacy of her home. Thanks to Scooper, who is mad with jealousy, and to her little sister Elspeth (Clare Foley) who combines the less endearing features of a stool pigeon, a blackmailer and the Marquis de Sade, they get no privacy...
