Imagine a simple dynamical system: on a circle. You have a point on a circle (an angle from 0 to 1). The rule: multiply the angle by 2, and take the fractional part. Start at 0.1. The orbit: 0.1 → 0.2 → 0.4 → 0.8 → 0.6 → 0.2 → ... It’s deterministic.
Now, suppose you don’t know the starting point exactly. You only know it lies in the interval [0.1, 0.101]. After just a few doublings, that tiny interval is stretched and folded across the entire circle. Your knowledge has become uniformly spread out: any final position is equally likely. dynamical systems and ergodic theory pdf
