Computation is understood as whatever made by a digital computer or something that can be emulated (or aproximated) by a digital computer. So everything is a computation. That is a useless definition. because it embrace everything.
Everything is legoland because everything can be emulated using lego pieces? No, my dear legologist. What about this definition? Computation is whatever that reduces entropy. In information terms, in the human context, computation is whatever that reduces uncertainty producing useful information and thus, in the environment of human society, a computer program is used ultimately to get that information and reduce entropy, that is to increase order in society, or at least for the human that uses it. A simulation is an special case of the latter. So there are things that are computations: what the living beings do at the chemical, physiological or nervous levels (and rational, social and technological level in case of humans) . But there are things that are not computations: almost everything else. -- Alberto. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
