I'm no physicist but I'm interested in physical information. It continues to amaze me how little attention is paid by most non-physicists to the very well established concept of information in physics. Of course, there is no "law" or formula that relates a bit of information to, say, quarks, spin, or whatever. These are different ways of looking at the same thing. Spin is a bit of information (I think it's just one bit, but I might be wrong, as I said, I'm no physicist.) Physical information is a re-conceptualisation of material form that allows it to be quantified. So, for example, physicists can (and do) say that information is generally conserved within black holes. (See the Black Hole Information Paradox, and the bet between physicists concerning it, http://www.theory.caltech.edu/~preskill/jp_24jul04.html) Now, there is obviously more to semantic information than material form, but it is my strongly-held belief that it should be possible to relate all other concepts of information back to physical information, and, in fact, I have proposed a way of doing that for semantic information, which I presented at the DTMD2011 workshop (I've also mentioned it in previous posts on this list), but I'll say no more about it here, because I think that's going too far off the current topic. -- Robin Faichney <http://www.robinfaichney.org/> _______________________________________________ fis mailing list fis@listas.unizar.es https://webmail.unizar.es/cgi-bin/mailman/listinfo/fis
