What is Time Good For, Anyway?

From ancient sundials to satellites in orbit, our ability to measure time has shaped both how we navigate the world and how we understand the universe.
In this public talk, Glenn Wong will trace the surprising history of timekeeping, from solving the problem of longitude at sea to the creation of time zones to Einstein’s revolutionary theory of relativity.

Along the way, explore the evolution of clocks, from water clocks and pocket watches to the atomic clocks that reveal time dilation and make modern GPS possible. By the end, discover why keeping time with incredible precision is not just a curiosity but the invisible foundation that enables many things we do in our everyday lives.

After the talk, join Sara Schechner, David P. Wheatland Curator Emerita of the Collection of Historical Scientific Instruments at Harvard University, as she shows off antique timekeeping devices from the Museum’s collection. No vitrines, just you and the objects.
