gambling is chaotic, unpredictable

a double pendulum is chaotic, easily predictable if you know nature laws

now im confused

what does chaotic mean?

i thought it meant unpredictable but seems not

I would not say that gambling is unpredictable - casinos and bookies make vast sums of money by staying away from outliers and improbability. Individuals have won raffles and even lotteries by purchasing majorities of tickets.

Not really. To predict it's future positions over a significant period, you would need not only to know 'nature laws', but its exact current state - this is of course impossible.

Chaos, no such thing, it's merely a function of order.

If your referring to CHAOS THEORY it's just a way of predicting the behavior of non-linear systems. The popular press have however made it into some arcane mystical rite. The best book on Chaos Theory for the non-mathematical lay person is probably still the one by James Gleick which came out over 20 years ago. It was a bit "oh wow gee whizz" sensational like all pop science but unlike the Esalon rubbish at least got the facts right.

In aerodynamics an example of a linear system is laminar flow and a non linear (chaotic) system is the turbulence that occurs after stall.

In terms of your double pendulum the literature indicates they initially behave like a linear system but for large movements become non-linear.
