On January 24, 1852, the French physicist Foucault successfully tested the world's first torque with a mass of 28 kilograms. At the funeral in Paris, Foucault successfully demonstrated the Earth's rotation experiment near its vertical position. Because Foucault's experiment directly verified the rotation of the Earth, he was awarded the Order of Honor of the Fifth Knight.
