====Computational irreducibility====
Wolfram argues that one of his achievements is in providing a coherent system of ideas that justifies computation as an organizing [[Philosophy of science|principle of science]]. For instance, he argues that the concept of ''[[computational irreducibility]]'' (that some complex computations are not amenable to short-cuts and cannot be "reduced"), is ultimately the reason why computational models of nature must be considered in addition to traditional [[mathematical models]]. Likewise, his idea of intrinsic randomness generation—that natural systems can generate their own randomness, rather than using chaos theory or stochastic perturbations—implies that computational models do not need to include explicit randomness.
