- The National Council of Science Museums (NCSM) based in Kolkata was installed the Foucault's Pendulum in new Parliament building.
- The pendulum takes precisely 49 hours, 59 minutes, and 18 seconds to complete a full rotation.
- It is a deceptively simple device used to illustrate the earth’s rotation.
- If the pendulum is installed at the North Pole, the pendulum will basically be swinging as the earth rotates ‘below’.
- If the pendulum is installed over the equator, the plane won’t appear to shift at all because it will be rotating along with the earth.
- Depending on where you are on Earth, the pendulum will appear to rotate in different ways.
