Google is celebrating Léon Foucault’s 194th birthday with a new interactive digital version of the Foucault pendulum doodle on its homepage.
Jean Bernard Léon Foucault (18 September 1819 – 11 February 1868) was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of the Earth’s rotation. He also made an early measurement of the speed of light, discovered eddy currents, and although he did not invent it, is credited with naming the gyroscope.
