The universe has wonders that can stun us — if only someone could be clear and vivid in explaining them to us. Neil deGrasse Tyson does just that, which has put him among the most recognized science communicators of the 21st Century. He’s not only an astrophysicist, an author, and the head of the world-renowned Hayden Planetarium, he’s also funny. In this episode Alan and Neil explore some surprising techniques for making hard stuff clear, including how a particular football play can explain the weird physics of how things swirl around on earth (like clouds in a hurricane, or water in a toilet bowl).
