Chaos means one thing in everyday language: unpredictable, out-of-control anarchy. In math and science it means something else. This kind of chaos is unpredictable in detail but predictable in its overall form. I recommend James Gleick’s great book on this topic: Chaos: Making a New Science, and I’ve talked about it before so I won’t go into it a lot here, but the one thing we often see here is self-similarity, where zooming in closer and closer you see the same overall pattern. Last winter I took this shot of bare tree branches against the sky. Big branches sprout smaller ones, which sprout twigs, which sprout twiglets (is that a word?), and so on down and down. At each level the type of branching that happens is the same as at the levels above and below. This is just really cool.
