Science of the 2012 Summer Olympics

"Science of the 2012 Summer Olympics," the fourth and latest installment in the "Science of Sports" franchise, explores the science, engineering and technology that are helping athletes maximize their performance at the 2012 London Games.

How does swimmer Missy Franklin use the principles of fluid dynamics to move more quickly through water? What are the unique biomechanics that have helped make sprinter Usain Bolt the world’s fastest human? What does weightlifter Sarah Robles have in common with a high-tech robot? How do engineers build faster pools, stronger safety helmets, and specialized wheelchairs for disabled athletes? Explore these and many other engineering and technology concepts in this free 9-part educational video series.

"Science of the 2012 Summer Olympics: Engineering in Sports" is a partnership with NBC Learn, NBC Sports and NSF's Directorate for Engineering.

Episode 1. Missy Franklin and Fluid Dynamics

U.S. swimmer Missy Franklin is one of the top medal contenders at the 2012 Summer Olympics. Just as engineers design planes and boats to be more aerodynamic, Franklin will need to master the basic principles of fluid dynamics in order to be the fastest swimmer in the pool.

Episode 7. Sarah Robles and the Mechanics of Weightlifting

U.S. weightlifter Sarah Robles will rely on an athletic mix of strength, speed and timing to help create explosive power when she competes at the 2012 Summer Olympics. Robotics engineer Brian Zenowich compares Robles’ movements to those made by the WAM Arm, one of the world’s most advanced robotic arms.

Episode 8. Maximizing the Long Jump of Bryan Clay

The long jump is one of the most technically challenging events in the decathlon, a track and field competition consisting of 10 events held over two days. In order to maximize his performance, 2008 Olympic gold medalist Bryan Clay teamed up with engineers from BMW to improve measurement of the horizontal and vertical velocities of his long jumps.

Episode 9. Measuring a Champion

Timing is everything, especially at the 2012 Summer Olympics where even a millisecond could mean the difference between victory and defeat. Linda Milor, an electrical engineer at Georgia Institute of Technology, explains why Olympic timekeeping technology must be able to measure an athlete's performance with both accuracy and precision.
