Opportunities 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.
