Google honours Leon Foucault's 194th birth anniversary with interactive Google doodle
Today, 18 September is the 194th birth anniversary of the famous French experimental physicist Leon Foucault. As a matter of respect, Google has honoured the French physicist with a google doodle on their homepage, which depicts a pendulum that was specially constructed by Foucault to prove that the Earth rotates around an imaginary axis.

The depiction of the doodle is as an interactive pendulum to illustrate the effect of Earth's rotation. The pendulum invented by Foucault was named after him, and is called 'Foucault's pendulum'. Furthermore by clicking on the magnifying glass icon, visitors on Google's homepage will be able to know more about Leon Foucault from various sources on the Internet.

It was in the year 1851 that Foucault with his pendulum was able to verify and confirm experimentally the theory of Earth's rotation. He found that the Earth completes one full spin once every 32.7 hours. He also made a gyroscope to measure the orientation of spinning and rotating objects.

Leon was born in Paris on September 18, 1819.  He studied medicine to become a medical practitioner but soon quit after having developed a fear of blood. Later, he took to physical sciences to become a famous experimental physicist.  He died at a young age of 48 due to multiple sclerosis in 1868. In 1864, he was made a member of the Royal Society of London as well.
