In this episode, Samuel Arbesman speaks with Sara Imari Walker, a theoretical physicist and astrobiologist at Arizona State University. Walker is the author of Life as No One Knows It: The Physics of Life’s Emergence, a book that explores the nature of life through the lens of physics and highlights her pioneering contributions at the frontier of this field.
Their conversation delves into how Walker became fascinated by the nature of life, how to distinguish life from non-life, and how physics can offer new insights into some of the universe’s most fundamental questions. Along the way, they touch on topics ranging from astrobiology and SETI to the philosophy of science and her work in assembly theory.
