Offbeat, entertaining and intellectually challenging, the Project X series sets out to demonstrate how science is everywhere in our lives.

In this episode on memory, microbiologist Dr. Jennifer Gardy looks at how elite athletes perform dazzling feats, seemingly without effort. She joins a group of British "free runners," athletes performing the urban street stunts, to explore how muscle memory works. Engineer Dr. Brian Fleck and grad student Marc Huot then unearth some surprising news in the classroom: students immediately forget 90% of information conveyed in a class lecture. Their experiments with some unsuspecting students help reveal why. Meanwhile, education expert Dr. Brian Alters meets Lawrence Farwell, the neuroscientist behind "Brain Fingerprinting" — a revolutionary new forensic technology that helps identify the criminal mind!
