Observations with high-speed camera and photoelectric cell show that an expert golfer may swing his club head as fast as 125 m.p.h. At such velocities air resistance becomes a considerable factor. At the American Physical Society's convention in Washington last week, Physicist Sylvan Jay Crooker of Purcellville, Va. reported that air resistance may be diminished fifteenfold by scientific streamlining of the club head, the shape (except for the face of the club) conforming to airship hull contours tested in wind tunnels. Declared Dr. Crooker: "Dynamic and ballistic analyses, checked by field tests,...
