Human Beings are inclined to associate 'order' with 'good', and 'chaos' with 'not good'.  This seems to be especially so if you were educated in the west during the past few hundred years.

A consequence is that we tend to think of order and chaos as opposites.

One view of chaos is that it's stochastic behaviour occurring in a deterministic system.

A deterministic equation may have a patternless outcome and a slight change in the equation's starting value means you loose track completely of where it's going.
