![]() Low entropy implies an unstable situation that will sooner or later follow its normal evolution toward stability and high entropy. The principal source of negentropy for terrestrial life is the sun, which acquired its low entropy state from the expanding universe followed by the collapse of material particles under the force of gravity. He then connected it to information in what he called the. This represents an entirely new field for investigation and a most revolutionary idea. Wiener suggests some practical and numerical definitions that may apply to the simplest possible problem of this kind. Do they have the same entropy? According to the usual physical definition, the answer is. Some examples may illustrate this new problem. Wiener introduces a precise mathematical definition of this new negative entropy for a certain number of problems of communication, and discusses the question of time prediction: when we possess a certain number of data about the behavior of a system in the past, how much can we predict of the behavior of that system in the future? We certainly must be prepared to discuss the extension of entropy to scientific knowledge technical know- how, and all forms of intelligent thinking.
