Description: Dr. Dave is actually a mechanical engineering professor at Colorado State University. A devoted pool player, he has set out to let us understand the physics of ball interaction, balls off the rail, and the reaction of the cue ball. The book, in easy to digest format, concisely states the concepts, then summarizes the key points. There are more than 250 illustrations and photographs and the accompanying CD-Rom or DVD actually show you the principles in action. This makes for an innovative way to learn as you don't have to visualize the outcome from text - it's happening, on your computer or TV screen, right before your eyes. Complete index and glossary. Soft cover - 274 pages.
