World Science Festival | Flame Challenge: What Is Sound?

Alan Alda has issued this year’s challenge to the world’s top scientists: What is sound? In an action-packed hour of interactive demonstrations, Alan and a team of communication experts invite the audience to explore what we hear, how we hear, and what that means for different species. The program also highlights the winners of the 2016 Flame Challenge, in which video and written explanations of sound were judged for clarity’s sake…by 20,000 eleven year-olds.
