I'm so happy that I propagated my love to earth sciences piece by piece, and let people know more about our Earth. Foucault Pendulum is such a great example to illustrate the rotation of the Earth. This simple experiment was beautifully conducted by Leon Foucault at the Pantheon in Paris in 1851. At the North Pole, the pendulum rotates 15 degrees per hour clockwise (opposite to the self-rotataional direction of the Earth); however, the period of rotation of the pendulum varies with latitude.
It's amazing, isn't it? (I think I just found another story for our newsletter!!)
