SUMMARY OF ACCOMPLISHMENTS
My first research work as a graduate student was to participate in the Nobel-prize winning “two neutrino experiment” under my advisor Jack Steinberger. My particle physics research since then mostly involved the analysis of elementary particle physics experiments. Some examples of specific accomplishments includes: (a) development of a new method of identifying elementary particle reactions, (b) search for evidence of free quark production in particle reactions, (c) searched for double beta decay reaction, (d) search for evidence of quantization of time in particle physics, and (e) analyzed solar neutrino experiment in light of neutrino oscillation hypothesis. My most recent particle physics work in the late 1990’s and early 2000’s involved looking at possible evidence for neutrinos being tachyons. Resumed this work in 2011 to currently.
During the 1980’s I explored national policies on nuclear weapons, the effects of nuclear weapons ("nuclear winter"), and the role of nuclear war education at the university level and initiated and organized three national conferences on nuclear war and peace education. Some fairly recent research interests include a study of how humans extrapolate motion, and a new theory involving the cause of quasiperiodic glaciations involving solar diffusion waves. I also continue to be interested in writing science for a broad audience, and studying physics education methods, and have written or edited 20 books on various subjects. During the past few years I conducted research and writing on renewable energy, culminating in a textbook on renewable energy (2013).
At SUNY-New Paltz, I Chaired
ten-person department during a difficult period of retrenchment at the
University. Revised curriculum so as to
improve enrollments while maintaining program quality and thereby preventing
loss of positions. Initiated two-year
engineering program which later evolved into a four-year degree program. After
Taught physics courses at all levels from introductory to graduate. Developed and taught innovative physics course, including: "How Things Work", "Computer Applications in Physics", and "The Life and Work of Einstein". Developed and taught interdisciplinary course, including: "The Nature of Time", "Survival in the Year 2000", "Nuclear War", and "The Decision-making Process and The Choice of Technologies," and Introduction to Renewable Energy.”
