What is Earth's Rotation Day?
Earth's Rotation Day marks the anniversary of Léon Foucault's 1851 demonstration of the planet's spin at the Paris Panthéon. By suspending a heavy pendulum from the dome, Foucault showed that the swing's plane appears to rotate as the Earth turns beneath it. Today, Foucault Pendulums in science museums worldwide continue to make this invisible motion visible.
