The Theory and Practice of Time Travel: A Syllabus, by David DeGraff

This class will look at both the scientific uses of time travel as well as their fictional uses. Students will learn the importance of distinguishing Personal (Proper) Time from Co-ordinate (Calendar) Time, how that distinction can be used to overcome the common objections to time travel in the history of literature, and how to use closed time-like curves to visit the past.
