Rimmer, you need to tell us a little about yerself. i hadn't seen you in these here parts until just recently. -- r b-j rbj@audioimagination.com "Imagination is more important than knowledge."

In Information Theory, though, he did more or less the equivalent of starting with whole cloth and producing the unified field theory. His foundations for information theory have been essentially unchallenged and unmodified until only the last few years. That's a pretty significant contribution, IMHO. ;) Eric Jacobsen Minister of Algorithms, Intel Corp. My opinions may not be Intel's opinions. http://www.ericjacobsen.org
