logic is an approach to computing based on "degrees of truth" rather than
the usual "true or false" (1 or 0) boolean logic on which the modern computer is based. The idea of fuzzy logic was
first advanced by
Dr. Lotfi Zadeh of the University of California at Berkeley in the 1960s. Dr. Zadeh was
working on the problem
of computer understanding of natural language. Natural language (like most other activities in life and indeed the universe) is not
easily translated into the
absolute terms of 0 and 1.
