Phase portrait of the Chirikov standard map: nested island chains inside a speckled chaotic sea.

Standard map

Chirikov. K = 0.971635, ninety orbits on the torus.

An area-preserving map of the torus, (θ, p) ↦ (θ + p′, p + K sin θ). At this K the last invariant circle has just broken, so islands of order sit inside a connected chaotic sea.
