Neil Theise (Notes on Complexity) is a diagnostic pathologist, stem cell biologist, and complexity theorist. Neil joins the Armchair Expert to discuss the principles of complexity theory, the way it works at different levels of scale, and how it differs from chaos theory. Neil and Dax talk about emergent self-organization, how randomness encourages change, and negative feedback loops. Neil explains the importance of your microbiome, how the universe is an endless unfolding range of possibilities, and how he learned to fear a lot less.
