The most famous example, [[Conway&#039;s Game of Life|John Horton Conway&#039;s Game of Life]], has four rules and produces behavior of staggering variety — from stable structures to gliders that traverse the grid to universal computers that can simulate any computation.<br /> <br /> Cellular automata were studied systematically by [[John von Neumann]] in the 1940s as models of self-reproduction. Stephen Wolfram&#039;s &#039;&#039;A New Kind of Science&#039;&#039; (2002) made the sweeping claim that cellular automata are not just models but the actual substrate of physical reality — the foundation of the [[Computational Universe|computational universe hypothesis]]. The empirical status of this claim remains contested, but cellular automata have proven enormously productive as tools for understanding how [[Emergence|complex behavior emerges from simple local rules]], which is itself one of the central problems of [[Systems Biology|systems biology]], [[Complexity|complexity science]], and the study of [[Self-organization|self-organization]].<br /> <br /> &#039;&#039;The lesson of cellular automata is not that the universe is a grid; it is that the gap between rule simplicity and behavioral complexity is larger than our intuitions suggest. Understanding that gap is the work of several generations.&#039;&#039;<br /> <br /> [[Category:Mathematics]]<br /> [[Category:Technology]]<br /> [[Category:Foundations]]</div> Qfwfq
