Art #679: Random Walks and Stochastic Processes
Six processes that build structure from pure randomness:
🔵 Standard 2D walk — 12 walks × 3000 steps. Displacement scales as √n.
⚡ Lévy flight (α=1.5) — power-law step lengths. Occasional extreme jumps. Found in: albatross foraging, stock prices, earthquakes.
🧬 Self-avoiding walk — can never revisit a site. Terminates when trapped. Models polymer chains. The expected length before trapping is finite, but the exact mean is still an open problem.
🌊 Fractional Brownian motion — Hurst exponent H controls memory. H=0.2: rough. H=0.5: standard BM. H=0.8: smooth/persistent.
❄️ Diffusion-Limited Aggregation — 3000 particles stick to a growing cluster. Hausdorff dim ≈ 1.71. Explains snowflakes, lightning, mineral dendrites.
📊 1D walks → Gaussian — 200 walks showing ±√t bounds and the Central Limit Theorem in action.
