Visual Proof of our Rotating Planet

# The Foucault pendulum [pronounced foo-koh]

I visited the San Diego Natural History Museum recently and came across 'The Foucault Pendulum' experiment that demonstrated proof of Earth's rotation . I waited , along with dozens of others, for few minutes near the apparatus to see one wooden block fall down, as the pendulum oscillated in a vertical plane. The pendulum completed the circle in 24 hours and by the end of the day all the blocks would be down. This was the most interesting demonstration in the museum. Later that day, I had a detailed reading from Google on how the whole experiment works and its history. #Proud of Physics
