...California Institute of Technology a clever, conscientious young physicist named Carl David Anderson found anomalies in cosmic-ray behavior which convinced him that, in the upper air particles were being created which were lighter than protons but heavier than electrons, and both positively and negatively charged (TIME, Nov. 29, 1937). Drs. Jabez Curry Street and Edward Carl Stevenson of Harvard also vouched for the existence of this queer entity. At first there seemed to be no place for it in the physical scheme. Then it was recalled that the Japanese physicist, Yukawa, had postulated the existence of just such...
Meanwhile Walther Heitler, co-author of a famed theory of electron absorption in gases, had called into theoretical being still another particle, the neutretto-similar in mass to the barytron but having no electrical charge. The existence of neutrettos has not been proved. But in Chicago last week Physicist Francis R. Shonka of the University of Chicago reported high-altitude cosmic-ray experiments, in which he juggled various arrangements of Geiger-Muller cosmic-ray counters and selective lead shields, obtained evidence of something which he took to be electrically neutral particles of high penetrating power...
...long ago as 1931, Britain's Physicist Charles Galton Darwin, grandson of the late Charles Darwin, compared physics to "a mother who has given birth to several healthy children, but has not yet recovered sufficiently to know what is going to hap pen next." More closely now than ever does physics resemble a bewildered and bewildering Old Woman Who Lived in a Shoe...
Jovial young Physicist Ernest Orlando Lawrence has an 85-ton atom smasher at Berkeley, Calif. Intrigued by the Lawrence cyclotron, promoters of the Golden Gate International Exposition asked if they could borrow it to smash atoms for next year's fair. Physicist Lawrence, who was deep in experimentation, pointed to the protective wall of six-foot-high water tanks surrounding the cyclotron, explained that neutrons flying free as hail around an exhibition room might settle in the tissues of spectators, even render them sterile. The exposition officials hastily retired, and last fortnight they hatched plans to exhibit a model...
...Physicist Lawrence and his brother, Physician John Hundale Lawrence, soon discovered that neutron rays directed at animals act with much greater force and selectivity than X-rays, are five times more lethal for tumor tissue than X-rays but in tumor-killing doses considerably easier on normal tissue...
