...captain of Cambridge University's famed Cavendish Laboratory, Ernest Rutherford, ist Baron Rutherford. The two great U. S. captains are Caltech's Robert Andrews Millikan and the University of Chicago's Arthur Holly Compton, cosmic ray specialists and milestone men in the history of the electron. France's No. 1 team of subatomic investigators is a devoted, captainless couple: Irene Curie-Joliot and Jean Frédéric Joliot, daughter and son-in-law of Marie Curie...
...experiments are based upon a generally accepted theory that the cosmic rays (high speed electrons, etc.), which are traveling toward the earth, cause a slight disintegration of the nuclei of the atoms of a substance through which they pass. The collision of a high speed electron with the nucleus knocks electrons out of it. The precipitation of these minute nuclear particles is known as a "shower...
...Physics and director of this research, when asked to comment on the possibilities of the work. "Since the photon leaves no track, it loses none of its energy in passing through the air. It there fore has much more energy with which to disintegrate the nuclei than the electron. As a result of this fact, it has a high efficiency in bombarding nuclei. It remains therefore only to discover the practical application of this fact...
...closest known approximation of the human eye (TIME, July 10). Designed for television, the device was called the iconoscope. On 20 square inches of mica were 3,000,000 dots of photosensitive material. Light falling on the mica set up an electromagnetic tension which was discharged by an electron beam. The changing pattern of this discharge could be transmitted by radio. At the receiving end the image was reproduced on a fluorescent screen by a reversal of the iconoscope's operating principle...
Wave mechanics and matrix mechanics are different mathematical expressions of the same theory. A third description of electron behavior, which strengthened rather than contradicted the other two representations, was contributed by last week's third prizewinner, Cambridge University's brilliant young Dr. Dirac. Also, long before lightweight protons or "positrons" were experimentally observed by Caltech's Dr. Carl David Anderson (TIME, March 6), Dr. Dirac had declared such particles to be required by mathematical necessity. But this shy, angular youngster with small Wack eyes and small black mustache, already a big frog in the subatomic puddle, made...
