HAROLD E. PUTHOFF, Ph.D., is the CEO of EarthTech International, Inc., which is dedicated to the exploration of new frontiers in the physics of spaceflight energy and propulsion. Formerly, he was a senior research engineer at Stanford Research Institute. Dr. Puthoff holds patents in the area of lasers and optical devices and has supervised research for doctoral candidates in electrical engineering and applied physics at Stanford University. In addition, he has initiated programs to study psychic phenomena from the standpoint of modern physics. RUSSELL TARG was a senior research physicist at Stanford Research Institute, where he worked with Harold Puthoff and coined the term “remote vieweing.” In 1982, he cofounded Delphi Associates, a psychic consulting service. He is author of more than two dozen articles on lasers, plasma physics, and psychic research. He is also the inventor of the tunable plasma oscillator at microwave frequencies, the FM laser, and the high-power gas-transport laser. With another inventor, he devised the ESP Teaching Machine, for training people in clairvoyance and precognition.
