None of his colleagues thought that it would ever be so high, but his forecast  actually proved to be too low. His philosophy on scientific computing appeared as the motto of his Numerical Methods for Scientists and Engineers (1962):
  In later life, Hamming became interested in teaching. Between 1960 and 1976, when he left Bell Labs, he held visiting or adjunct professorships at Stanford University, Stevens Institute of Technology, the City College of New York, the University of California at Irvine and Princeton University. As a Young Turk, Hamming had resented older scientists who had used up space and resources that would have been put to much better use by the young Turks. Looking at a commemorative poster of the Bell Labs' valued achievements, he noted that he had worked on or been associated with nearly all of those listed in the first half of his career at Bell Labs, but none in the second. He therefore resolved to retire in 1976, after thirty years.
  In 1976 he moved to the Naval Postgraduate School in Monterey, California, where he worked as an adjunct professor and senior lecturer in computer science. He gave up research, and concentrated on teaching and writing books. He noted that:
