intelligence. But this intelligence is not that of a machine. It is that of the designers who have conceived the machine and developed the code that is operated by the machine. Hence, the old-fashioned appellation of artificial intelligence, which, despite its phenomenal information-processing power, only emulates human intelligence. The man-machine intelligence challenge is well illustrated by chess contests, where the latter often wins but only for reasons of memory (having registered all champions' strategies in chess history) and computing power (having the possibility to analyze several moves in advance). The chances to win over the machine are higher if the player adopts some tactics that the machine has not prerecorded or cannot figure out the rationale thereof. One may recall Arthur C. Clarke's 2001: A Space Odyssey (of which S. Kubrick made the famous movie), in which HAL, 3 the mightiest supercomputer ever designed in history, is eventually defeated by Dave, the more intelligent astronaut. For those who do not know the story, HAL could not compute the possibility that Dave would take a life chance by forcing his way back to the space station without wearing a helmet. The computer's intelligence may be virtually unbounded, but it is also exposed to some gaps in which human beings may easily compete. Computer hackers are here to illustrate that the most sophisticated firewalls can be broken into by means of exploiting such gaps. But that is another debate. Since information is not about intelligence, what would be the use of an information theory? Could information theory ever be a science, as information science is to com- puters? Let us look at this question more closely. In accurate terminology, information science (or informatics), is a branch of computer science. Corresponding definitions go as follows:4 Information science is primarily concerned with the structure, creation, management, storage, retrieval, dissemination, and transfer of information. It also includes study- ing the application of inf
