Tuning in to Nature
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.
