About the Author
Dr. Philip S. Callahan is a philosopher as well as a top-grade scientist. An internationally famous entomologist and ornithologist, he has been responsible for breakthrough discoveries in both areas. He is also an explorer who has walked across mainland China and the Syrian Desert, observing the intricate ways of man and nature wherever he went.
He entered the U.S. Army Air Force in 1942, and served two years in the European Theater of Operations during World War II. Hiking around the world after he war, he worked as a freelance photographer and writer. Later, he attended Fordham University and received his B.A. and M.S. degrees from the University of Arkansas and his Ph.D. from Kansas State University. He served as assistant professor of the Entomology Department at Louisiana State University and later joined the U.S. Department of Agriculture, Southern Grain Insects Research Laboratory as Project Leader for Insect Biophysics. He was also Professor of Entomology on the graduate faculty of the University of Georgia. In 1969 he transferred to USDA Insect Attractant and Behavior Laboratory at Gainesville, Florida. Callahan served as a full professor on the graduate faculty of the University of Florida, and on the staff of The Olive W. Garvey Center for the Improvement of Human Functioning, Inc. as an infrared systems and low energy consultant.
His research involved the utilization of nonlinear far infrared radiation by biological systems and its applications to insect control and medicine. He has developed theories of insect communication based on the waveguide characteristics of insect spines and has postulated that such spines are thermoelectret-coated dielectric waveguide aerials with the ability to receive short wavelength IR and microwave frequencies. His work in biophysics might best be called studies in insect molecular bioelectronics.
He is the author of more than 100 scientific papers and numerous books, including: My Search for Traces of God; A Walk in the Sun; Nature's Silent Music; Ancient Mysteries, Modern Visions; Tuning in to Nature; and, Paramagnetism.
