Dear all, Happy the New Year of 2014 and the coming Chinese New Year of the horse (to be successful when the horse comes!) I would like to say that John's work on the collection of literature of PI and the very idea of Information is really helpful, thanks! Cheers, Xiaohong XJTU-ICPI

Date: 2014-01-14 13:58 Dear FIS members, Information has various scientific usages, and it is important for people to be clear which one they mean. None of the meanings is canonical, but they can be put in relation to each other, as I do in Kinds of Information in Scientific Use. 2011. cognition, communication, co-operation. Vol 9, No 2. Another good source dealing with relations of different concepts of information is Luciano Floridi's elementary book, Information A Very Short Introduction (Oxford University Press, 2010). Also The Philosophy of Information (Oxford University Press, 2011). I recommend these to people on the FIS list to those who cannot get their minds around the idea that the information concept has a wide range of diverse uses that are nonetheless related to each other. Floridi is especially good on the issues of signals versus data versus interpreted information. All are information in the most general sense on his account. On the issue of the first use of information theory, I note that Shannon, C.E. (1948), "A Mathematical Theory of Communication", Bell System Technical Journal, 27, pp. 379423 & 623656, July & October, 1948. uses 'information' extensively as what is communicated, so the title could have easily been A mathematical theory of communication of information. The article is widely regarded as the foundation of information theory. However Hartely's 1928 paper, "Transmission of Information", Bell System Technical Journal, July 1928 is much earlier. Szillard made the connection between information and physics in his L. Szilárd (1929) "Über die Entropieverminderung in einem thermodynamischen System bei Eingriffen intelligenter Wesen" (On the reduction of entropy in a thermodynamic system by the intervention of intelligent beings), Zeitschrift für Physik, 53 : 840-856. Available on-line in English at: Aurellen.org (see also Leon Brillouin, Science and Information Theory, Mineola, N.Y.: Dover, [1956, 1962] 2004. ISBN 0-486-43918-6). It is unclear to me who introduced the actual term 'information theory', but it was in common use after 1948. The following might be instructive: http://web.mit.edu/6.933/www/Fall2001/Shannon2.pdf Cheers, John At 05:42 AM 2014-01-13, Xueshan wrote: Dear Rafael, I am sure you were right in "what is communicated between a sender and a receiver is NOT information but a MESSAGE", I can provide you more supports from Biology. Between two nerve cells, between gland cell and target cell, it is MESSENGERS but not others which carry MESSAGE from sender to receiver, this is the situation in first messenger theory. In second messenger theory, not message or information, they call it SIGNAL. In computer science, DATA some time was adopted, such as Data Structure, Data Bank, Data Mining. No matter what happens, all message, signal etc. should recognize as a special usage of information. This is an interesting history in past related information explorations. But in modern science, such in semiochemistry, when talk about the effects of pheromones, allomones, kairomones, attractants, repellents, most Chemists like to use information rather then signal (or message). First and last, shall we consider INFORMATION as genus and MESSAGE, news, knowledge, etc. as its differentia? By the way, who knows who are the first people who called Shannon's "Mathematical Theory of Communication" as "Information Theory"? What time? Where?
