Cosmic Rays

'We are constantly exposed to a thin rain of highly energetic, potentially harmful charged particles called cosmic rays, which emanate from exteterrestrial sources. Friedlander describes the history of cosmic rays and how they are identified. . . There are no other recent books on this subject for the lay person. Will organized, well written, informative, and interesting, this book is a worthy addition to anyone's library.' -Reuben Benumof, Science Books and Films
