[Unedited] Carlo Rovelli with Krista Tippett

Physicist Carlo Rovelli says humans don’t understand the world as made by things, “we understand the world made by kisses, or things like kisses — happenings.” This everyday truth is as scientific as it is philosophical and political, and it unfolds with unexpected nuance in his science. Rovelli is one of the founders of loop quantum gravity theory and author of the tiny, bestselling book Seven Brief Lessons on Physics and The Order of Time. Seeing the world through his eyes, we understand that there is no such thing as “here” or “now.” Instead, he says, our senses convey a picture of reality that narrows our understanding of its fullness.

Carlo Rovelli is professor of physics at Aix-Marseille University, where he is director of the quantum gravity group in the Center for Theoretical Physics. He is also director of the Samy Maroun Research Center for Time, Space, and the Quantum. His books include Seven Brief Lessons on Physics and, most recently, The Order of Time.
