Description: Foucault’s pendulum, named after the French physicist Léon Foucault. Conceived as an experiment to demonstrate the rotation of the Earth. Made in 1851. Focault suspended a 28-kg brass-coated lead bob with a 67-metre -long wire from the dome of the Panthéon, Paris. The plane of the pendulum’s swing rotated clockwise 11° per hour, making a full circle in 32.7 hours. Jean Bernard Léon Focault ; French physicist 18 September 1819 – 11 February 1868
