Current Research Interests
Robert Ehrlich is a recently retired Physics professor at George Mason University. His current research interest is in finding evidence for the reality of faster-than-light particles—which has recently led to a new paper presenting some tantalizing results. You may also be interested in this press release and a physics colloquium based on the paper, which he would be happy to give in person at your university, his schedule permitting. Ehrlich is also interested in renewable energy, and promoting renewable energy education—see, for example his junior-level 2013 textbook Renewable Energy: A First Course, and his course web site, PHYS 331 Fundamentals of Renewable Energy. A complete list of his publications can be found on his resume. You may also be interested in a 7-minute interactive explanation of relativity for the layperson: “Relativity: Adventures of Albert and Marie,” and his humorous video speculating what Einstein might have to say about tachyons (posted below). In his spare time, Ehrlich is hopelessly addicted to the game of Go.

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.
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.
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 moving to George Mason University in 1977, I Chaired the department until 1989. During that time I oversaw the growth of department from eleven to twenty-two full-time faculty prior to the splitting off of electrical engineering in 1984. Made personnel decisions and recommendations regarding hiring, tenure, reappointment, annual evaluation, and salary increments. Advanced affirmative action goals by hiring capable female and minority candidates, and by supporting programs for young women considering careers in science. Supervised clerical and technical personnel, and managed the department budget. Initiated and developed new programs: three engineering programs, including one at the masters level, and a masters program in applied physics. Resumed the role of department chair in Fall 2006.
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."
