Self-Organized Criticality
In physics, self-organized criticality (SOC) is a property of (classes of) dynamical systems which have a critical point as an attractor. Their macroscopic behaviour thus displays the spatial and/or temporal scale-invariance characteristic of the critical point of a phase transition, but without the need to tune control parameters to precise values.

How Nature Works: The Science of Self-Organized CriticalityMany seemingly disparate aspects of the world, from the formation of the landscape to the process of evolution to the action of nervous systems to the behavior of the economy, all share a set of simple, easily described properties. These properties are all so similar, Per Bak writes, that they ...

Stefan BoettcherResearch on Self-Organized Criticality: It has been observed that self-similar (``critical'') structures are quite ubiquitous in nature, and the question as to the dynamical origin of those structures arises. Some years ago, Self-Organized Criticality (SOC) was proposed as one mechanism to ...

Bak–Tang–Wiesenfeld sandpile - Wikipedia, the free encyclopediaIn physics , the Bak–Tang–Wiesenfeld sandpile model is the first discovered example of a dynamical system displaying self-organized criticality and is named after Per Bak , Chao Tang and Kurt Wiesenfeld . The model is a cellular automaton . At each site on the lattice there is a value ...

Per Bak - Wikipedia, the free encyclopediaPer Bak Others about Per Bak "He was the most American of Danes," said Predrag Cvitanović . "Danes eschew confrontation, but he was arrogant and loved to fight with his colleagues in academia. We all have stories of how we first met him, usually remembered by some outrageous statement or insult." ...
