There are many events that might be interesting to general audiences, for example "From Aristotle to the iPhone" by Moshe Vardi: "This talk tells the story of how logic begat computing, tracing the surprising path from Aristotle to the iPhone. This is a story full of both intellectual drama, as well as real-life drama, with most of the characters dying young, miserable, or both." https://events.rice.edu/#!view/event/event_id/155303
