Timing is everything, especially at the 2012 Summer Olympics where even a millisecond could mean the difference between victory and defeat. In the video, "Measuring a Champion," Linda Milor, a professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology, explains why Olympic timekeeping technology must be able to measure an athlete's performance with both accuracy and precision. "Science of the Summer Olympics: Engineering In Sports" is a 10-part video series produced in partnership with NBC Learn, NBC Sports, and the National Science Foundation Directorate of Engineering.

"Measuring a Champion" (all with runtimes of 5:34) may be viewed at the web sites for the National Science Foundation, Science 360: The Knowledge Network, & NBC Learn. Shorter versions of all of the videos will be broadcast during the 2012 Summer Olympics, which will be held in London July 27-August 12. Lesson plans for K-12 teachers will be available online in August 2012.
