DIVIDING A SECOND
ELECTRIC-TIMING DEVICE One-liundredih part of a second divided by live. No one will deny that this is a rather small grain in the hour glass of time. Nevertheless, the business of dividing a second into these parts comes all in a day’s work to the official timers of the annual 500-mile race held at the Indianapolis Motor Speedway on Memorial Day. The dissection of seconds is accomplished through an electrical timing device which is believed by speedway officials to be the only one of it-s kind in the world. A copper wire is stretched about an inch and a-half above the surface of the brick track directly in front of the stand occupied by the judges of the race. As the front wheels of the racing cars depress the wire, an electrical impulse is transmitted to a chronometer. This, in turn, operates a set of small metal hammers which print the correct figures on a tape in much the same manner as a typewriter or ticker.
