It’s clear that the sprinter in the middle crossed the finish line first. But in Olympic races, it’s often not easy to tell who won the race.

Amazing but True!

  • When world-class athletes compete, the winning athlete may be just a split second ahead of the athlete in second place.
  • Knowing who won, as well as everyone’s time, requires both accuracy and precision. An Olympic medal may be resting on it!
  • Since the “modern” Olympics began in 1896, measuring the time of champions has come a long way.
  • Today, differences as small as one-thousandth of a second can be measured! How do they do it? Watch this video to find out:
