A Survey of Progressive Science

Abstract

AMONG the many aspects of progress in physics which tempt reference is that concerned with cosmic rays, so fascinating to most minds are speculations concerning their nature. Thinking of the more recent developments in this subject, one would like to express admiration of the enterprise which has enabled Prof. E. Regener to obtain records from many miles up in the atmosphere and deep below the surface of Lake Constance for measurements of their varying intensity; admiration no less for the similar enterprises of Compton and Kolhorster. It is interesting to learn that Regener, as the result of the most recent researches by himself and colleagues, has formed the personal opinion that a part at least of cosmic radiation is electromagnetic.
