There Are No Equal Signs in Biology

There Are No Equal Signs in Biology

From Evolution 2.0 by Perry Marshall

About this episode

Perry Marshall discusses the limitations of mathematics in biology and its implications for medicine with Jay Cross.

Jay Cross interviews me about my new paper, The Reasonable Ineffectiveness of Mathematics in the Biological Sciences (co-authored with Sy Garte and Stuart Kauffman.) Together we explore why “there are no equal signs in biology,” how this revelation redefines medicine as we know it, and the post-computational, post-permission future of healing—with new hope for people facing serious health challenges. Jay is an accomplished direct response copywriter and researcher with great interest in the “third transition” in science, and this conversation opens that up in a big way. Hosted on Acast.
