If I understand you correctly, it seems that location (the description of a location) is just a form of what you call "state". I think it's a rather complex thing to try to measure information in general. What we generally call "information" only becomes "informative" in a specific context. How to measure the amount of information in the context? It takes about 10 bits to store any location on this planet with 1 degree resolution, but this "information" requires a lot of context to actually lead you to the spot it describes. How many bits are in the context? Gerhard -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
