Philip S. Callahan, Ph.D.

For more than twenty years it has been my fascination to work in a field that I like to term “reverse bionics.” Man has throughout the ages, by his intellectual and inventive processes, developed systems and workable technologies completely independent of any corroborating or parallel processes in nature. One of the most striking examples of such a system is the complex arrays and antenna forms developed and utilized in modern electronics.

This book is the culmination of all of Callahan's previous works and will certainly be his most popular book to date and a classic for years to come. Quite frankly, the author considers this his most important work ever, as he believes an understanding of paramagnetism —and its practical integration into farming— can save agriculture worldwide.

In this one, beautiful little book, Callahan lays out a lifetime of research into low-frequency forces in nature and his discoveries regarding the force of paramagnetism and the amazing effects it has upon soils, plants and people. Join Phil Callahan as schooling, research, life experiences, insight and inspiration come together for the benefit of humankind. Amply illustrated by the author.

I am an entomologist. I study insects for a living. Whenever I catch myself thinking that I know more about insects than do most people, I promptly think of a conversation in Oliver Wendell Holmes’ The Poet at the Breakfast Table:

"I suppose you are an entomologist? 
Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name. No man can be truly called an entomologist, sir; the subject is too vast for any single human intelligence to grasp."

Most entomologists would be more than willing to agree with Holmes’ speaker. Of all the living creatures, the insects are the most wondrous. Not also the most numerous. they are the most numerous. There are estimated to be aout 900,000 different species of insects. Of this number, entomologists have so far described only about 685,000 (or about three-quarters), leaving over 200,000 species to be described by future entomologists.

I have prepared this report primarily to answer queries entomologists about electronic techniques I have used in my ecological studies of the corn earworm, Heliothis zea (Boddie). In these studies, conducted for the most part at the Southern Grain Insects Research Laboratory at Tifton, Ga., during 1962- 63, I utilized certain original circuit with an asterisk standard circuits, which designs can be found in in the References Cited I modified the publications section on page slightly. These on electronics marked 9 of this report.

This report includes descriptions of basic semiconductor circuitry for accurate measurements of an insect's environment and behavior; some methods for using Ohm's law to calculate resistance in meter-recording circuits; an explanation of the characteristics of photoconductive and photovoltaic cells, thermistors, and pressure-sensitive microducers; and a presentation of schematics and examples of many simplified semiconductor circuits I have used to study the environment and behavior of the corn earworm moth.

The entire electromagnetic spectrum is covered in this book, everything from the short radioactive waves used to sterilize male screw flies so the female lays sterile eggs; to the long-wave radio frequencies that penetrate the soil, control and enhance root growth and the immune system of plants and animals. Explains not only the visible-light spectrum, but also the invisible high-energy nuclear and low-energy infrared and radio portions of the electromagnetic spectrum.
