  Bayesian mechanics is a new approach to studying the mathematics and physics
of interacting stochastic processes. Here, we provide a worked example of a
physical mechanics for classical objects, which derives from a simple
application thereof. We summarise the current state of the art of Bayesian
mechanics in doing so. We also give a sketch of its connections to classical
chaos, owing to a particular $\mathcal{N}=2$ supersymmetry.
