d Institute of Physics. Dr. Martin Pomerantz, a physicist who specialized in cosmic ray research, had a long and distinguished career in polar studies. As a graduate student at the University of Pennsylvania he took a challenging course in 1938 at the Bartol Research Foundation of the Franklin Institute, a course called Cosmic Rays and Nuclear Physics. At the time, 01/01/1993 · Forbush either discovered or put on a firm basis for the first time the following fundamental cosmic-ray effects: The quasi-persistent 27-day variation of intensity.The diurnal variation of intensity. The sporadic emission of very energetic (up to ≈GeV) protons by solar flares. Worldwide impulsive decreases (Forbush decreases) in intensity.
