If we didn’t have vast civilizational challenges upon us, we might be living in a constant state of wonder at what science in this century is learning and showing us about the cosmos and about ourselves — the new questions it’s giving us to live. We are the generation of our species to map the genome, to detect black holes colliding, to hear gravitational waves. The physicist Brian Greene is one of our greatest interpreters from the human enterprise that is science. And in his most recent thinking and writing, there’s a stunning evolution in his own approach to science and life and the matters of purpose and meaning. We delve into his exuberant, cosmic lens on living in the here and the now.

Brian Greene is a professor of physics and mathematics at Columbia University, where he is also the director of Columbia’s Center for Theoretical Physics. He is the co-founder and chairman of the World Science Festival. His books include The Elegant Universe, The Hidden Reality, The Fabric of the Cosmos, and most recently, Until The End Of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe.
