“What Is Life?” is an eight-episode podcast series recorded in front of a live audience. (Subscribe to the podcast at iTunes, via RSS, etc.) In this episode, I spoke to astrobiologist Sara Imari Walker.
Sara Imari Walker is a physicist and astrobiologist at Arizona State University. She studies life as a physical phenomenon, in order to develop new ways to search for it elsewhere in the universe. We shouldn’t assume that aliens will introduce themselves to us, so we need a way to recognize life no matter what form it takes.
What Is Life? was recorded in front of a live audience at Caveat in New York and is supported by a grant from Science Sandbox, a Simons Foundation initiative. Artwork by Caryn Audenried.
