Central Idea

The Foucault pendulum is a device that proves the Earth’s rotation and has been installed in the new Parliament building in New Delhi.
It was designed and installed by the National Council of Science Museums (NCSM), Kolkata.

Foucault Pendulum: A Unique Invention

Historical Context: In 1851, the Foucault pendulum experiment conclusively demonstrated the Earth’s rotation, settling debates about the planet’s movement.
Leon Foucault: The French scientist invented the Foucault pendulum and invited scientists and the public to witness the Earth’s rotation through the experiment.
Working: The pendulum consists of a heavy iron ball suspended by a steel wire and swings in a plane, mimicking the Earth’s rotation on its axis.
Exhibition at the Pantheon: The demonstration took place at the Pantheon in Paris, where the ball’s motion represented the Earth’s rotation.

Earth’s Rotation as a Scientific Fact: The Foucault pendulum experiment solidified the understanding that the Earth rotates on its axis.
Supporting Astronomical Studies: The knowledge of the Earth’s rotation is crucial for studying various astronomical phenomena, such as day and night cycles and seasonal changes.
Continual Scientific Inquiry: The Foucault pendulum experiment encouraged further research into the Earth’s rotation and its implications for our understanding of the universe.

Educational Installations: The inclusion of a Foucault pendulum in the new Parliament building in New Delhi provides an opportunity for public education and scientific engagement.
Technological Advancements: Advances in technology, such as precision instruments and digital monitoring, can enhance the accuracy and impact of Foucault pendulum installations.
Continued Research: Ongoing scientific studies and experiments can deepen our understanding of the Earth’s rotation and its relationship to other celestial bodies.
Space Exploration: Exploring the Earth’s rotation from space can offer unique perspectives and insights into its dynamics.
