Wikipedia: "The thesis of A New Kind of Science (NKS) is twofold: the nature of computation must be explored experimentally, and the results of these experiments have great relevance to understanding the physical world. [...] [Wolfram] argues an entirely new method is needed to do so because traditional mathematics fails to meaningfully describe complex systems, and there is an upper limit to complexity in all systems."
