Sandpile as a paradigm of SOC Bak & Chen, Sc. Am. 1991 • “Self-organized” means systems reaching critical states without tuning. • “Critical”: at critical slope (“angle of repose”), no characteristic avalanche size exists. It covers all possible values with power-law distribution P(s)~s -b .
Open-boundary conditions are important to ensure self-organized criticality Number of jobs thrown out of window obeys P(n)~n -b
