Self-Organized Criticality
The sandpile self-organizes to a critical state without tuning. Avalanche size s has power-law distribution:
P(s) ∝ s^(−τ), τ ≈ 1.2 (2D)
This means small and huge avalanches follow the same law — no characteristic scale. The same mechanism governs earthquakes (Gutenberg-Richter), forest fires, and solar flares.
