Michael Weissman is a Professor Emeritus of Physics at the University of Illinois at Urbana-Champaign and a Fellow of the American Physical Society. He has worked mostly on condensed matter experiments, especially on low-frequency noise in disordered materials. He has worked in botany and chemistry departments. His undergrad degree is in math. He stumbled into looking at physics education research papers by accident. He did time for Vietnam draft resistance and was an originator of the scientists’ boycott of the Strategic Defense Initiative. He thinks that libertarian philosophy is factually detached from the realities of our species, implicitly cruel, and will lead to environmental catastrophe. He supports unions but not the designated-hitter rule. His email is mbw@​illinois.edu.
