Julian Bashir took the Elementary Temporal Mechanics course. After travelling back in time to James T. Kirk's USS Enterprise, Bashir was worried that Dierdre Watley was one of his own ancestors and that he was involved in a predestination paradox and might have to become his own great-grandfather. Bashir had learned about predestination paradoxes in Elementary Temporal Mechanics. (DS9 episode: "Trials and Tribble-ations")
