Self-Organized Criticality,ngerprint of deterministic chaos. However, although fluctuations are ubiquitous in many natural phenomena, nature is obviously not completely irregular. Otherwise, phenomena involving a certain degree of order, such as life, would be impossible. From this point of view, nature often seems to be some

,The Forest-Fire Model — Tuning and Universality,. A first version of this model was published by Bak et al. (1990), but Drossel and Schwabl (1992) were the first to discover SOC uniquely in a modified approach. Although it is even simpler than the BTW model (Sect. 5.2), the forest-fire model has some relevance to nature as the sizes of real fores

SOC and Nothing Else?,e may be tempted to look for SOC whenever fractals or fractal distributions occur. However, we should be aware that SOC is just one mechanism for explaining scale invariance. It is perhaps the most interesting one because it is still poorly understood, and perhaps even that with the widest field of
