Koehler, Jack H. 1989. The Science of Pocket Billiards. Laguna Hills, CA: Sportology Publications. Signed Jack H. Koehler 6-23-95. Rare. The Science of Pocket Billiards covers the entire spectrum from basics to the most advanced concepts of pool. There are 262 pages (81/2 X 11) crammed with information along with 33 photographs and 277 illustrations to help clarify the material presented. The occasional player can skim through the book and learn enough for a lifetime of casual play while a serious student of pool can study this book for months or even years and continue to gain valuable knowledge. From the Author: I am a scientist by profession. During my career I have authored more than twenty published scientific reports. My books on pool are the result of more than 40 years of observation, participation, and experimentation. In my books I focus on scientific reasoning as opposed to unverified opinion in developing and explaining the concepts of pool. Although scientific principals are followed, the books are written in easy to understand layman's terms. My constant underlying objective is to present knowledge that will improve the readers pool game.
