The Useful Knowledge podcast is all about big ideas and the people behind them. Each episode features a Member of the American Philosophical Society (APS) or one of our grant and fellowship alumni, all sharing the significance and impact of their work across diverse fields. Join host Patrick Spero, CEO of the APS, in conversation with guests on topics spanning science, history, the arts, and beyond, and see how knowledge of any kind can spark curiosity, solve problems, and enrich the world.
