Contacting Dr. Scott was a suggestion from my math-whiz friend Peter after I asked who he considered to be the Great Mathematicians of our times. Dana S. Scott has taught at Berkeley, Princeton, Stanford and Oxford. He won the Turing Award (1976). I cannot sum up well what he has accomplished, so I have had to resort to Wikipedia which describes Dr. Scott as: “Internationally recognized mathematical logician whose work has spanned computer science, mathematics, and philosophy. He made seminal contributions to automata theory, modal logic, model theory, set theory, and the theory of programming languages.”
