We all experience some form of recurrence in our daily lives. However, this year at TEDxPurdueU we seek to explore how recurrence influences our lives at a deeper level. How does recurrence manifest in our social or scientific landscape? How does it impact our political or historical spheres? Join TEDxPurdueU as we explore the variety of ways recurrence is embedded into our shared experience of life. Boundary-pushing experts from Purdue University and beyond present their work in the classic TEDx format of bite-sized talks that are 18-minutes or less.
