I doubt that very much. Negative entropy implies probabilities greater than 1. Probabilities have always been in the range [0,1] in any version of QM I have worked on. Of course there is such a thing as Negentropy, but negentropy is actually a positive quantity. I don't think it is what you're looking for. -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
