The planned course is based on a book by a famous physicist David Mermin of Cornell University. Mermin spent several decades teaching this course to undergraduate science and non-science majors and perfected the pedagogical approach. Relativity is a difficult subject that is nevertheless a cornerstone of the modern understanding of the world. An on-line delivery of the course will allow interested students to include the course into their schedules, avoiding time conflicts with the required classes. The offering will be an opportunity for students of all majors with good knowledge of basic school math. It can be very helpful to engineering students who plan to work with satellite navigation systems, philosophy students, and of course physics majors as well.
