Both the uncertainty principle and the negentropy principle of information make Laplace's scheme [of exact determinism] completely unrealistic. The problem is an artificial one; it belongs to imaginative poetry, not to experimental science.

The laws of classical mechanics represent a mathematical idealization and should not be assumed to correspond to the real laws of nature. ... We now have to realize that errors are inevitable (..) a discovery that makes strict determinism impossible.
