                Foam physics and artificial intelligence — how everyday bubbles reveal the hidden science of learning and complex systems in nature.

                This episode uniquely connects foam physics explained with the science of learning in AI, showing how materials that learn and the physics of everyday materials mirror what is artificial intelligence doing under the hood.
                Listen to discover how AI inspired by nature may uncover a universal logic linking foam bubbles science, artificial intelligence and physics, and living cells.

                • How typical wet foam can pack an astonishing 10^8–10^9 bubbles per liter and why that matters for understanding complex systems in nature.
                • Why foams were once modeled like glassy, frozen materials—and what new simulations reveal about their constant microscopic motion.
                • What a T1 rearrangement is, how a single event lowers surface energy by about 10^-12 joules, and why that tiny change is a powerful unit of ‘learning-like’ behavior.
                • How more than 10^4 T1 events per second in a fist-sized foam sample create a dynamic, self-optimizing structure that still keeps its overall shape.
