Published: Noise equals control. I detail an explicit mapping between stochastic systems and control theory, showing how goal-directed behaviour arises from purely causal stochastic systems. Illustrated with stochastic resonance & Brownian ratchets journals.aps.org/pre/abstract...

My talk from @bioctrl.bsky.social about the physical origin of agency is uploaded here: youtube.com/watch?v=YY21... TLDR: noise equals control. Nature is constantly sampling control trajectories via noise

I'm very excited about this virtual talk, tomorrow at 11am ET, and open to everyone! I will explain precisely how and why agency is part of Nature, and illustrate the idea with some examples from biology and beyond. No complex mathematics.
