...carrying balloon can ever take scientists above the stratosphere, Dr. Harlan T. Stetson, Harvard University Research Associate in Geophysics in his lecture on "Exploring Beyond the Stratosphere" at the Institute of Geographical Exploration last night stressed the importance of investigating this ionosphere, the most sensitive district for effects of cosmic origin...
...Stetson concluded, "Important changes in the electric and magnetic characteristics of the atmosphere and the earth in this region of the globe will prove a new incentive for geographical exploration in the future. Extensive journeys already made by cosmic ray specialists have yielded valuable results, and the future will see new tools and equipment accompanying an increasing band of workers into these newer fields of exploration...
Lopsided Magnet. Since Earth is a vast magnet with North and South magnetic poles, it has a magnetic field which extends thousands of miles out into space. If cosmic rays are largely charged particles, as most physicists believe, their intensity should be affected by terrestrial magnetism. It has been discovered that, as the field is strongest near the poles and weakest at the Equator, so is the cosmic ray bombardment strong or weak with changing latitude. Later a longitude differential was found. Last week, with intensity figures for electroscopes carried on nine ships sailing the seven seas. Robert Andrews Millikan...
Determination of whether cosmic rays resemble electrons or photons and their origin may be settled by data collected by Albert W. Stevens, lecturer in aerophotography, and Orvil A. Anderson in their stratosphere flight Monday, according to Harlan T. Stetson, research associate in Physics, who, among others, advised Captain Stevens about his scientific instruments when he was at Harvard last spring...
...Stetson explained that there are two conflicting theories, Arthur Compton, of the University of Chicago, believing that cosmic rays are chiefly made up of electrons, and Millikan believing that they are chiefly made up of photons, bundles of light energy...
