The Foucalt pendulum, named after French physicist Léon Foucault, was used to demonstrate the rotation of the Earth. A heavy wire with a large swinging metal ball on the end would change position as the Earth rotated. The tower was removed in the early 1980's due to safety concerns. The concrete pit remained until 2015, when it was removed to make way for the Veteran's Corridor. The pendulum was located between the 5400 and 5500 buildings.
