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.
