Google’s latest doodle marks the birthday of Jean Bernard Léon Foucault, the French physicist and inventor of a pendulum that demonstrated the rotation of the earth.
The Foucault pendulum was created by Léon Foucault to provide experimental evidence that the Earth rotates on its axis. A son of a publisher, his full name was Jean-Bernard-Léon Foucault. He was born on September 18, 1819 in Paris.
Léon Foucault’s pendulum doubles as the Google doodle on his 194th birthday.
In the Foucault pendulum doodle with the help of controls on the right allows a users to replicate changes in the trajectory of the Earth’s rotation over time and quite like the original Foucault pendulum, it knocks down pins at different positions as time elapses and the Earth rotates.
The letters in the Google logo are spelt out as inscribers on the pattern on the ground below the pendulum. The Foucault pendulum was first demonstrated in 1851 when Foucault suspended a heavy iron ball from a wire and used the motion of the ball to prove that the Earth rotates on its axis.
The pendulum demonstrated in the Google doodle is a copy of the Foucault’s Pendulum in the Panthéon, Paris. Léon Foucault also developed a method to measure the speed of of light. Though Foucault studied medicine he later switched his interests to experimental physics.
Foucault died of multiple sclerosis on February 11, 1868 at the age of 48 after being made a member of many of the top scientific societies in Europe. He was buried in the Cimetière de Montmartre, with his name among those of seventy-two French scientists, engineers, and mathematicians engraved on the Eiffel Tower. The asteroid 5668 Foucault is also named after him.
