Just listen to little kids pester their parents, “But why?” and you know how ingrained human curiosity is. And a good thing too—it drives scientific research, inspires creativity in art and technology, and is a necessary ingredient in every form of storytelling. But have you ever been curious—about curiosity? How did we humans get to be so inquisitive and why? In this podcast, astrophysicist and best-selling author Mario Livio explores the origins and mechanisms of human curiosity. Part of the monthly Frontiers Lecture series, this talk took place at the Hayden Planetarium on September 18, 2017.
