...clear their research shelves toward the close of an academic year. At the American Physical Society's convention in Washington last week the X-particle, newest and queerest of physics' collection of atomic particles, which weighs much more than an electron but much less than a proton (TIME, Nov. 29). came in for a good deal of housewifely attention...
...will probably never be identified as it is too big to be an electron and too small to be a proton. Nevertheless, its discovery is a tremendous achievement in Physics...
...mass of a proton (at rest...
...Europe may be looked upon as a nucleus composed of individual protons, not, however, all of the same size or power, mixed up with a few neutrons of no charge and little mass. This is kept together by a strong force which prevents them flying apart, known as geography. This nucleus is not symmetrical as, included on its western edge, is a particularly powerful proton (Britain) that has 'wave characteristics' of a definite type peculiar to itself. In the south there is what might be called a neutrino (Italy). This has, some think, also wave mechanic aspirations...
...pictures Dr. Street obtained two tracks which seemed significant. One was ruled out, however, as a proton. The other was obviously not a proton, yet its track was about six times as heavy as could be expected from an electron. It was clearly ticketed as an X-par-ticle. Counting the fog droplets as carefully as he could and taking into consideration the track's curvature as bent by a magnetic field, Dr. Street figured its mass at 130 times the mass of the electron-with a probable error of 25% either...
