...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...
From the latitude effect on cosmic rays, Dr. Compton deduces that they are magnetically attractable corpuscles of electricity (electrons or protons) and not, as Dr. Millikan has theorized, intractable corpuscles of light (photons...
...kind of cosmic ray. Some rays pierce the earth's atmosphere more easily than others. If they are all electrons, those which reach sea level-reasons Dr. Compton-must have as much as thirty billion volts behind them. Dr. Compton's estimate is untenable, argues Dr. Millikan. Photons at five hundred million volts make just as big a splash in an electroscope as might electrons many times stronger...
Caltech's Dr. Paul Sophus Epstein, mathematical physicist, patted the proud heads of both great scholars last week, much as his whimsical friend Dr. Albert Einstein, who still was in Pasadena, might have done. Nobel Laureates Millikan & Compton are both correct in their theories, testified Dr. Epstein. Of cosmic rays which reach earth's atmosphere. 30% are Compton electrons (or protons) and tend to congregate around the magnetic poles. The remaining 70% are Millikan photons, darting right through the air to land...
