This episode is with Chris Kempes, a professor at the Santa Fe Institute working at the fascinating intersection of physics and biology. Chris joins us to talk about some of the most profound questions about life starting from fundamental definitions to exploring life's potential multiple origins guided by the laws of physics. Join us as we explore the role of energy landscapes in Prebiotic chemistry, the physical basis of microbial behaviors, scaling laws that govern life's metabolic patterns, and how collective behaviors emerge in multicellular organisms. Let's embark on a journey to rethink life's mysteries through the lens of physics.
