Book excerpt: The book entitled How Golf Clubs Really Work and How to Optimize Their Design ($29.95), is the first book published that focuses on the golf club and the way that golfers can utilize their specific clubs to achieve better shot control, leading to lower scores for all golfers. The book is the end result of a 10-year, full-time dedicated research effort for co-authors Frank D. Werner and Richard C. Grieg. Both have advanced degrees in aerospace engineering and together have over 90 patents. The authors have discussed many issues relevant to the game of golf and analyzed the way that different factors play a part in shot making. Chapters are included on optimal face curvature (bulge and roll may be extinct), shaft length and head weight to maximize distance, and the effects of wind drag on club head speed (less than you would expect). In addition, the authors have developed new aiming and shot control techniques that could allow golfers to have better control, hit more fairways and greens, and lower their scores. The book will provide useful insights for a broad spectrum of golfers from touring pros and teaching professionals to struggling beginners and serious golfers looking to shave a few strokes off their game. By providing an analysis of all that happens from impact until the ball stops, the authors have de-mystified one of the world's greatest games.
