Flocking

At what level of noise does a flock stop flocking?

How the lab tests it

Raise the heading noise η step by step and measure the polar order φ(η), locating where coherent motion collapses.

This is one world in the PHS lab — 91 interactive simulations, each posing a question and measuring the answer. See the catalogued findings.
