...carbon must be the stuff that enables the sun to turn fragments of hydrogen atoms into sunshine (TIME, Feb. 27). Lately he has been working on the function in the atom's nucleus of a particle called the "mesotron," which weighs about 200 times as much as an electron, about one-ninth as much as a proton or a neutron. His findings, completed last week, will shortly be published in Physical Review...
...Carl David Anderson of Caltech announced the existence of an intermediate particle, apparently created about ten miles up in the air by cosmic ray impacts, and its existence was also vouched for by Street & Stevenson of Harvard. The particle was variously called the "X-particle," the "heavy electron"' (a misnomer, since it was not an electron), the "barytron" (also a misnomer, because it means "heavy particle," whereas the particle is lighter than a proton). A name meaning "intermediate particle" was clearly in order, and so practically all U. S. physicists now call it the "mesotron" or "meson...
Uranium Attack. The Department of Terrestrial Magnetism has a powerfully equipped atom-smashing laboratory, headed by Dr. Merle Anthony Tuve. Early this year, when two Germans announced disintegration of the heavy uranium atom with release of 200,000,000 electron-volts of energy (most powerful man-made atomic explosion), Dr. Tuve and co-workers promptly confirmed the discovery, added the find that the uranium fragments become radioactive, continuing to emit particles for a few seconds after the impacts have stopped...
...final energy of millions of electron volts achieved by the projectiles equals the sum of the energies of all of the separate pushes...
Previous-lightning measurement has relied mainly on the oscillograph, which records the changing intensity of a bolt by means of an oscillating electron beam playing on photographic film. The fulchronograph is not only cheaper to use, says Westinghouse, but furnishes a clearer lightning picture...
