Spotlight on Numberphile: A Conversation with Brady Haran

Join filmmaker Brady Haran of YouTube's Numberphile for some math-filled excitement of his own devising. (You'll be glad you did.)

This pre-recorded event is provided with closed captioning.

Science Circus

The Science Circus is a goofy battle between playfulness and the laws of physics. Giggle as juggler Rhys Thomas tries to outwit gravity with a bowling ball then daringly risks his Mom’s plates in a throw-down with inertia! Marvel as he turns a sphere into a gyroscope that is stable on a kid’s head. Ponder as he uses math to create juggling tricks. And gasp as he searches for an equation powerful enough to save his toes from the Ladder of Swords. It’s a battle everyone wins by sharing the physics of fun.

This event is an encore broadcast of the live performance from March 17, 2021.
