...Jauncey's Electrons. One storm centre is an able, bald, self-critical physicist named George Eric MacDonnell Jauncey, who adorns the faculty of Washington University at St. Louis. Recently at a convention of scientists in Indianapolis, Dr. Jauncey described experiments which convinced him that the rest-masses of beta rays (fast electrons) shooting out of Radium E were variable (TIME, Jan. 17). He passed his electrons through a velocity selector, then estimated their masses by their behavior in electrical and magnetic fields. Since then Dr. Jauncey has bombarded the Physical Review with numerous communications backing up his announcement...
Some weeks ago George Eric MacDonnell Jauncey got a hunch that the X-particle was originally an ordinary electron whose mass had somehow been increased. He imagined what would happen if a high-energy cosmic ray photon struck an electron in the upper atmosphere. Most of the transferred energy would simply give the electron a high-velocity kick. But some of it might be converted into matter which the electron would absorb, increasing its mass. The increase might be any amount at all, depending on the initial energy of the cosmic ray and the variable quantity of matter produced...
...Jauncey cudgeled his brain for some way to verify experimentally the variable mass of electrons. On December 18 he hit on the idea of passing the electrons from Radium E through a velocity selector, then into a magnetic field. If the particles, selected for uniform velocity, were also of uniform mass, they should be uniformly curved by the field and would strike a photographic film in the same place. By that time the physics department at Washington University was so excited that Jauncey was offered the run of the laboratory and all the help he wanted. He stayed...
...days & nights Jauncey and his helpers worked almost without interruption to make other films. When the A. A. A. S. meeting opened at Indianapolis on December 27, they were ready with their results but it was too late to fit them into the program. Nevertheless news of what Jauncey was doing had leaked out into the scientific world and the physicists were so anxious to hear him that a special conference was arranged. Dr. Charles Thomas Zahn of the University of Michigan, who had been independently working along the same line, was summoned by telegraph, arrived, reported that...
Born 50 years ago in Australia, George Eric MacDonnell Jauncey arrived in the U. S. in 1914, studied at Lehigh, joined the Washington University staff in 1920. He likes detective stories and P. G. Wodehouse, is the author of some 75 technical articles and of Modern Physics, a popular college textbook. He realizes quite well the need for further checking of his findings. "I'm out on a limb now," he said philosophically last week. "I hope this thing stands up." He also said that he had got his original hunch while reading TIME'S story...
