Baker's map

A simple model of mixing: bake the dough by stretching and folding. Conjugate to the Bernoulli shift on bi-infinite binary strings, the cleanest example of measure-theoretic chaos.

Baker's map applied to a horizontally striped image: stretch, cut, stack.

Equations

Stretch the unit square 2× horizontally, cut, and stack.
