The Book Club has taken a short summer break and will return in September with new episodes. Until then, here’s an episode from the archives with the theoretical physicist Carlo Rovelli. Carlo joined Sam in March 2023 to discuss his book Anaximander and the Nature of Science and explain how a radical thinker two and a half millennia ago was the first human to intuit that the earth is floating in space. He tells Sam how Anaximander’s way of thinking still informs the work of scientists everywhere, how politics shapes scientific progress and how we can navigate the twin threats of religious dogma and postmodern relativism in search of truth.
