-Deterministic chaos occurs when nearby initial conditions separate exponentially fast in state space. This has been given the name **butterly effect**: the perturbation to the atmosphere's state caused by a butterfly flapping its wings could end up being magnified to modify the direction in which a tornado moves.

 We can see this in a simple way by perturbing the initial condition slightly and calculating the distance between the two systems as a function of $t$:
