In 1851 French physicist, Léon Foucault, constructed a simple pendulum where at the base, placement of pegs arranged in an arc are struck by the bob as the pendulum rhythmically oscillates above. The plane of oscillation appears to rotate eventually knocking each peg but this effect is that of the Earth rotating underneath. This was the first experiment of its kind that visually demonstrated the rotation of Earth about its axis. Enjoy this physics simulation presented in 3D themed in Steampunk genre! Includes • History and reference • Settings including receiving notifications when pegs are about to be knocked over • An immersive 3D rotunda demonstrating the principles of a Foucault Pendulum • Locate other pendulums operating around the world!
