Completely out of curiosity: what's the most shocking example of chaos you know? Something that shows (to a non-expert audience) how quickly errors grow in a chaotic system.
For example, I was thinking of something along these lines:
If you simulate a frictionless billiards table with 1000 balls, but you omit the gravitational pull of Pluto, your simulation will be completely wrong in less than a minute.
This particular example is probably not true, but that's the type of statement I'm looking for. Can you think of any examples?
References, or even back-of-the-envelope calculations are appreciated.
