Precise timing of sporting events

Lack of precise time measuring apparatus for athletic and other sporting events has led to the development of an electric timing system which is accurate to within 0.005 sec for short races and within 0.01 sec for a mile race. This system utilizes a synchronous electric clock and a high speed motion picture camera to photograph simultaneously the runner and the clock dials at the finish of the race. It was put to a practical test in the 1932 Olympics held in Los Angeles, Calif.
