...honest Dr. Robert Andrews Millikan, a fact is a fact. Last week he recognized a new one. Although it fortified the cosmic ray theory of Dr. Arthur Holly Compton, who had become Dr. Millikan's opponent in the field of cosmic ray theories (TIME, Jan. 9), Dr. Millikan at once published his new finding...
...fact: Cosmic rays are less intense above the Isthmus of Panama than above more northerly California. Latitude, Dr. Millikan now admits, has a definite effect on cosmic rays. They are strongest near the earth's magnetic poles, weakest near the magnetic equator. Dr. Compton has been proclaiming just that...
...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...
...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...
