In this paper, I describe a lay course in special relativity (SR) given at the Osher Lifelong Learning Institutes (OLLI's) at Florida International University and the University of Miami. Courses are also offered in general relativity quantum theory cosmology the nature of time, and the fine-tuned universe. Each course is presented in six hour-and-a-half weekly sessions. Students are mostly retired or semi-retired adults like me. Most are college educated, but with little or no formal physics education.
