Description: As long-cherished postulate of theoretical physics, the principle of stationary action (SAP) defines the basis of classical mechanics and field theory. We argue here that SAP is overturned in dynamic regimes where sensitivity to initial conditions cannot be ignored. Attempts are made to bridge the gap between Hamiltonian chaos and effective field theory.
