As a sociologist—and not even a mathematical one—the author can’t help feeling like an interloper at this conference. However, the author do not intend to talk to you about the social importance or, for that matter, about the theoretical meaning of what you are doing. A new science, or a new branch within a field of science, or, if you want to call it so, a new specialty within a given field, characterized by a set of methods, techniques, and theories too esoteric for the outsiders to follow fully, has been in the process of establishing itself. Nevertheless, the author find it amazing that so eminently political an activity can be discussed in such generally unpolitical terms. Anything concerned with computers is basically the province of a younger generation with its own technology: hardware, software, and new intellectual activities—of which global modeling is one of the newest.
