Chaos Theory Simulation
Explore sensitive dependence on initial conditions and routes to chaos via the logistic map and attractors. Small changes can lead to radically different outcomes.
📚 Fundamentals
- Deterministic yet unpredictable: sensitivity dominates long-run prediction
- Bifurcations: parameter changes cause period doubling to chaos
- Attractors: fractal structures in phase space
🧪 Logistic Map
x_{n+1} = r x_n (1 - x_n). As r increases, behavior transitions from fixed points to chaos.
❓ Frequently Asked Questions
1) Is chaos random?
No. It's deterministic but exhibits sensitivity and aperiodicity.
