...puffs from the first explosion is the Milky Way, in which Earth is a fleck of Sun-warmed soot. Other puffs are nebulae traveling 12,000 miles a second. Cosmic rays include flashes of light (Millikan photons) from that explosion, and chips of matter (Compton electrons and/or protons; TIME, Jan. 9). They equal one-tenth the light from all the stars and weigh (Millikan calculation) 10 -34 gram per cubic centimeter.* Mount Wilson's Astronomer Edwin Powell Hubble estimates the total amount of matter in space as 10 -31 gram per cubic centimeter. Cosmic radiation thus must be equal...
Escorted by Mayor R. M. Russell '14, B. W. Holmes '03, Dean of the Graduate School of Education, C. W. Killam, professor of Architecture K. T. Compton, president of the Massachusetts Institute of Technology, and a group consisting of members of the Cambridge School Board, made an inspection tour Sunday afternoon of the million-dollar Rindge Technical School which has been recently completed...
...along the walls lay the paraphernalia of modern science. In every seat sat a scientist tensely waiting to hear how oppositely the two U. S. Nobel Laureates in Physics explained cosmic rays-Dr. Millikan, 64, preacher's son, head of California Institute of Technology; and Dr. Arthur Holly Compton, 40, preacher's son. professor at the University of Chicago. Although the Laureates spoke alternately, their speeches had the effect of dramatic dialog...
...Nothing has happened which alters in any essential way the views expressed in my last comprehensive report," said Dr. Millikan stridently. What had happened included: Dr. Millikan's sending electroscopes by airplane to measure cosmic rays over Peru, the U. S., Canada; Dr. Compton's journeying with an electroscope around the Pacific and over North America from Mexico City to north of Churchill on Hudson Bay; two young men killed carrying a cosmic ray scope up Mt. McKinley; Professor Auguste Piccard & aide ballooning into the stratosphere ten miles above Switzerland; Professor Erich Regener sending a free balloon with...
...persistent view after 15 years is that cosmic rays are photons, or particles of light. He believes they originate from the creation of matter between the stars. But where they originate was not the nub of last week's symposium. What they are was the point. Dr. Compton declared again that they were electrons (and/or photons) coming to earth from beyond the atmosphere, or originating at the top of the atmosphere. When a photon hits an atom in the atmosphere, the atom emits an electron. When an electron hits an atom, the atom emits a photon. Dr. Millikan declares...
