My research has been in
field of Empirical Logic, the logic of quantum physics. The goal of the
research has been to create and explore logical systems which are
generalizations of Hilbert space, and which reflect all the logical features
of orthodox quantum mechanics without the paradox of the EPR dilemma inherent
in the orthodox system. My book, Introduction to Hilbert Space and Quantum
Logic (Springer-Verlag, 1989) was the first book on this topic accessible
to advanced undergraduates and beginning graduate students.
I also have a deep and
interest in teaching, and developed a group-oriented teaching method inspired
by the late R.L. Moore.
I've had the pleasure and privilege of teaching Introduction to Mathematical
Analysis with this method for more than 20 years (See reference  below for a description of the course and the method.)
I currently use this method to teach Infinite Dimensional Linear
(MTH 221), a new course designed for our strongest incoming
students. I also enjoy being
Game-Master for courses in history based on the
Reacting to History program developed by Mark Carnes at Barnard College.
Born and raised in Hartford,
Connecticut (Weaver High School 1958), I've lived in New England all
except when living abroad on sabbatical (Sweden, Switzerland and France
year each.) My hobbies include flying, film editing, travel, cooking and
eating. I also dabble in financial management and investing, and carpentry.
I married Doris Stein (Weaver
High School, 1959---although we didn't know each other in high school). We
have two daughters: Bonnie Cohen, MD, and Sara Cohen, MS, MUP, both living in
Somerville, Mass. at the moment. Our favorite hangout is on Prince Edward
