Chaos Theory Predictability

Discussions center on chaos theory, explaining why deterministic systems like double pendulums or weather are unpredictable due to sensitive dependence on initial conditions. Commenters reference Wikipedia, videos, and examples to argue against perfect predictability in complex systems.

You're being pedantic.Chaotic systems, in essence, are known for its unpredictability. Watch this to get an idea: https://www.youtube.com/watch?v=pEjZd-AvPco

I believe you are talking about Chaos theory [1][1] https://en.wikipedia.org/wiki/Chaos_theory

Possibly it's a chaotic deterministic system, which means it can't be precisely predicted by any means short of a full simulation.

Ain't that a chaotic system which is not deterministic?

dmbche Jun 20, 2025 View on HN

Look into Chaos Theory - the universe is not deterministic, you're good.Or for a tldr look for the three body problem or try to find a solution to a double pendulum!

This seems like a nice example of chaotic system (https://en.wikipedia.org/wiki/Chaos_theory).

Sounds like chaos theory -- small "variations" in the initial starting conditions can take you to a whole different place

ph0rque May 30, 2018 View on HN

Yes, a chaotic system which is hard to predict.

taneq Feb 20, 2019 View on HN

No, but it is probably a chaotic system (in the 'sensitive dependence on initial conditions' sense).

The system is chaotic so even in principle it’s likely impossible.
