Many and bewildering are the tiny speeks of matter which participate in the phenomena of nuclear physics, and the last few years have seen a frantic scientific big-game hunt which has successively laid low electrons, protons, positrons, photons, neutrons, alpha and gamma particles. After approximately three years of research, physicists Street and Stevenson have definitely decided that yet another particle should be added to the list. They haven't named it yet, feeling that they should become a little better acquainted with their research-child before they give it an identity...
...made by sub-atomic particles could be seen. At about the same time Hans Geiger, now of the University of Tubingen, invented a cylindrical "counter" which crackles every time a particle enters it. Physicists use both devices, alone or together, to record the presence of and identify cosmic rays, gamma rays, X-rays, photons, electrons, protons, positrons, neutrons...
...number of years physicists and engineers have been working on the problem of providing a source of very high voltage X-Rays which would approximate in wave length the gamma rays of radium, and which could be produced in intensities equaling the output of several hundred grams of this element...
Then in the New Lecture Hall at 8 o'clock three of the University's leading scientists join in a symposium on "Climate in the Living World." Participants, sponsored by the Gamma Alpha scientific fraternity, are William C. Darrah, Research Curator of the Botanical Museum and instructor in Botany; Kirtley F. Mather, professor of Geology; and Derwent S. Whittlesey, associate professor of Geology...
