“Bak postulated that power laws are the consequence of the build-up of complexity in systems due to various forms of self-organization. Self-organization is an emergent process of complex systems whereby simplicity is gradually replaced by complexity. The process is considered ‘self-organizing’ because to the outside observer, the emergence of complexity is intrinsic; it is contained within the system itself. In most systems, however, self-organizing requires energy to transform or rearrange the inner workings of the system.”
