What is the name of the pendulum which was used to show that the earth is spinning?
The Foucault Pendulum
The Foucault Pendulum is named for the French physicist Jean Foucault (pronounced “Foo-koh), who first used it in 1851 to demonstrate the rotation of the earth. It was the first satisfactory demonstration of the earth’s rotation using laboratory apparatus rather than astronomical observations.
What did Foucault’s pendulum confirm?
Foucault’s pendulum is an easy experiment demonstrating the Earth’s rotation. At the north or south pole, the pendulum is moving in a fixed plane (if we disregard the fact that the Earth is also revolving through space), so the plane of the pendulum seems to rotate through 360° as the Earth makes one full rotation.
Who invented the Foucault pendulum?

Where is the Foucault pendulum now?
While the original pendulum is now housed at the Musée des Arts et Métiers, a working copy is displayed at the Panthéon and has been swinging there since 1995.
Why is pendulum considered a landmark in the history of science?
From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping, and was the world’s most accurate timekeeping technology until the 1930s. Pendulums are also used in scientific instruments such as accelerometers and seismometers.
Where is the world’s largest pendulum?
The world’s longest pendula were two lengths of number 24 steel piano wire, each 1,353.3 m (4,440 ft) long. They were suspended down the number 4 shaft of the Tamarack Mines, near Calumet, Michigan, USA, in September 1901. The experiment was performed by Professor Fred W.
Who studied the pendulum?
