I am coordinator of the Engineering Program at HWS, and have served many years as Physics Department chair.
Lectures and Presentations
I have a range of lectures, technical and popular, that I am happy to give. Some samples:
The Anacapa Society
I am one of the founding members and also a current Board member of the Anacapa Society, a society dedicated to the support of theoretical physics research at primarily undergraduate institutions. If you want to learn more about this society or about theoretical physics at undergraduate colleges, check out the website of the Anacapa Society. You can find out where our name comes from, how to join, and lots of other information.
Over the years, I have taught many courses at HWS. The full list is Physics through Star Trek, Classical and Quantum Information and Computing, Astronomy, Modern Physics, Mathematical Methods, Symbolic Computing, Optics, Mechanics, Quantum Mechanics, Thermal Physics, Potpourri of Physics, Introductory Physics I (Mechanics and Waves), Introductory Physics II (Optics and Electromagnetism), and Contemporary Inquiries in Physics (advanced topics in theoretical physics, including symmetries, field theory, KdV equation, non-linear systems, supersymmetric quantum mechanics, and Monte Carlo methods), along with four first-year seminars: Reflecting Science (how science actually gets done, the intersection of science and the arts, explores the implications of science for public policy and of public policy for science), and Chaos, Black Holes, and Time Travel and Time Travel and Multiple Universes (exotic ideas of physics, both established and speculative, and a consideration of the impact of these ideas not just in science but in the arts, philosophy, politics, and society), and the successor course, Einstein, Relativity, and Time.
I have currently undertaken a research project exploring the use of the set theoretic notion of forcing to develop a transfinite theory of information, generalizing Shannon's work. This work incorporates the use of the notions of generic real numbers to generalize Jaynes's maximum entropy princple.
Over the years, my research in theoretical physics has focused largely on supersymmetry. This has led me to a consideration of supersymmetric quantum mechanics with a central charge, which provides a window into BPS and duality in new contexts, and in number theoretic approaches to the Hagedorn temperature. Other areas of interest of mine include Q-balls, exactly solvable systems, shape invariance, magnetic monopoles and other topological solitons, anyons, sigma models, exact results in supersymmetric field theories, p-adic string theories, the connections between supersymmetry and mathematics, and partial supersymmetry. I am especially interested in the application of supersymmetry to non-supersymmetric models. Additionally, I have supervised student research on such topics as time-dependent quantum mechanics and simulated annealing.
Outside physics, my research covers many cross-discplinary areas. With Antal Spector-Zabusky, I have developed and implemented a graphical halftoning algorithm that employs a maximum entropy principle. I am investigating the use of ideas from physics to provide analytical tools to the principles underlying computational complexity classes. I have also developed a systems analysis of weapons of mass destruction and an interpretation of Waiting for Godot that is based on the tension between the Copenhagen and Many Worlds Interpretations of quantum mechanics. Most recently, I have turned my attention to music, looking at connections between the mathematical formulation of the vacuum and the music of John Cage, and examining various mathematical interpretations of Terry Riley's piece In C.
