How nature builds complexity | Ricard Solé | Reason with Science | Liquid brains | Synthetic worlds
Episode 82
This conversatio is with Ricard Solé, a leading thinker in complex systems and synthetic biology. Ricard heads the Complex Systems Lab at Pompeu Fabra University in Barcelona, where he explores how simple rules give rise to life’s astonishing complexity.
We open with a thought-provoking question: Can a biologist fix a radio? — an idea from Yuri Lazebnik that asks if breaking things down into parts really explains how living systems work. Ricard explains why life resists simple mechanical analogies and why cells, organisms, and ecosystems can’t just be “wired up” like machines.
Together we explore what we mean by “complexity,” how nature builds it through evolution, self-organization, and cooperation, and why emergence makes the whole more than the sum of its parts. We touch on termite nests, slime molds, brains, and immune systems as windows into collective intelligence and hidden patterns in nature.
