9Opportunities and Challeges
- It is these boundary regions of science which
offer the richest opportunities to the qualified
investigator. - These specialized fields are continually growing
and invading new territory. The result is like
what occurred when the Oregon County was being
invaded simultaneously by the United States
settlers, the British, the Mexicans, and the
Russians an inextricable tangle of exploration,
nomenclature, and laws. There are fields of
scientific work, as we shall see in the body of
this book, which have been explored from the
different sides of pure mathematics, statistics,
electrical engineering, and neurophysiology in
which every single notion receives a separate
name from each group, and in which important work
has been triplicated or quadruplicated, while
still other important work is delayed by the
unavailability in one field of results that may
have already become classical in the next field. - Norbert Wiener - Cybernetics Or Control and
Communication in the Animal and the Machine.
