There seems to be some confusion between superposition and interference. In crude terms, we do live in a superposition |green T.Rex> + |blue T.Rex>. It may well be that |green T.Rex> and |blue T.Rex> are orthogonal, ie <green T.Rex|blue T.Rex>=0 (at FAPP), in which case the two histories do not interfere, and there is no quantum interference phenomena. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Senior Research Fellow hpco...@hpcoders.com.au Economics, Kingston University http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
