Part 1 of the TED Radio Hour episode Friction.
Have you brushed your teeth today? Or gotten a shot recently? As tribologist Jennifer Vail explains, these mundane activities are among the many in our daily lives that are made possible by friction.
About Jennifer Vail
Jennifer Vail is a tribologist, meaning she specializes in the study of friction, combining mechanical engineering and materials science to understand how surfaces interact in relative motion.
She's worked on a wide variety of projects, from aerospace materials to syringes to dog food. She has also studied how friction can be used to reduce energy consumption and produce longer-lasting materials.
Previously, Vail worked at DuPont as a research scientist. She now works for TA Instruments and creates science videos for Khan Academy.
She earned her bachelor's and her doctorate in mechanical engineering from the University of Florida.
