"Today's Google Doodle is a tribute to French physicist L\u00E9on Foucault, best known for his Foucault pendulum, which demonstrates the rotation of the Earth on its axis. Foucault was born on September 18, 1819, and died on February 11, 1868; today is the 194th anniversary of his birth. \n\nThe Doodle is an interactive one, letting you adjust the time and the position on Earth. As you change these two values, the pendulum knocks over pins in various positions around it. \nFoucault's pendulums are today often placed in museums and universities. One of the largest can be found at the Griffith Observatory in Los Angeles, California. \nSee also: The 10 Most Popular Google Doodles of 2012\nHow do you like today's Doodle?
