I am a physics professor who researches the physics of sports. My major research investigations include the aerodynamics of World Cup soccer balls, modelling the Tour de France, and examining friction between tennis shoes and hard courts. My first book, Gold Medal Physics: The Science of Sports, is pitched at a level that does not exceed introductory physics. It covers some great moments in sports. My second book, The Physics of Krav Maga, has no equations and takes readers into what might be the first scientific examination of one of the fastest-growing martial arts in the US. I enjoy media interactions that allow me to put science on the sports pages.
