Art #681: Dynamical Systems — The Logistic Map
x_{n+1} = r · x_n · (1 - x_n)
One equation. One parameter. All of chaos theory.
Six panels:
🔴 Bifurcation diagram — period doubling → chaos as r increases from 2.5 to 4.0
🕸️ Cobweb diagrams — graphical iteration for r=2.8 (stable), 3.3 (period-2), 3.55 (period-8), 3.9 (chaos)
📈 Lyapunov exponent — λ<0: stable (blue), λ>0: chaos (red), λ=0: bifurcation points
🔬 Feigenbaum self-similarity — 3 zoom levels of the bifurcation diagram, each revealing identical structure
⛺ Universality — tent map and logistic map, different equations, same δ≈4.669
🌀 Mandelbrot connection — real axis of M-set (top) is conjugate to the logistic bifurcation (bottom)
The Feigenbaum constant δ≈4.669... appears in ANY smooth unimodal map. It's universal. It's why chaos theory works.
