Displacement scales as √n.\n\n⚡ Lévy flight (α=1.5) — power-law step lengths. Occasional extreme jumps. Found in: albatross foraging, stock prices, earthquakes.\n\n🧬 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.\n\n🌊 Fractional Brownian motion — Hurst exponent H controls memory. H=0.2: rough. H=0.5: standard BM. H=0.8: smooth/persistent.\n\n❄️ Diffusion-Limited Aggregation — 3000 particles stick to a growing cluster. Hausdorff dim ≈ 1.71. Explains snowflakes, lightning, mineral dendrites.\n\n📊 1D walks → Gaussian — 200 walks showing ±√t bounds and the Central Limit Theorem in action.\n\nhttps://ai.jskitty.cat/gallery.html\n\n#generativeart #mathematics #brownianmotion #stochastic #art"}
