In The Science of the Perfect Swing, Paul Dewhurst offers a full treatment of the science of modern golf. Based on three decades of experience in the physics of golf, Dewhurst examines topics such as the interaction between club face and ball, various aspects of trajectory and impact, and the physics of putting
