Foucault's Pendulum
The pendulum is named after Leon Foucault. The pendulum demonstrates the motion of a mathematical pendulum under the influence of the rotation of the Earth. One of the most popular installations of a real Foucault's pendulum is located at Musée des arts et métiers in Paris, France. The famous philosopher and novelist Umberto Eco wrote a novel named Foucault's Pendulum.

The Coriolis force causes the pendulum to change its oscillation plane. On the north and south pole (latitude = 0 or ) the Coriolis force is zero and the pendulum will behave there like an ordinary pendulum. On the equator the Coriolis force has its maximum value and the control for the latitude control ranges over [0, ].
