The Earth rotates every day, but today is Earth’s Rotation Day. Read ahead to find out all about this special day.
It is known that the Earth rotates on its axis every 24 hours. This rotation around its axis is known as one Earth Day. However, this information was disputable for a long time. It wasn’t this clear until 1815. French physicist Leon Foucault demonstrated the Earth’s rotation using his now-famous pendulum. Around the world, Foucault’s Pendulums are a fixture in science museums.
In Paris, the French physicist Leon Foucault demonstrated how the Earth rotates by suspending a lead-filled brass ball from the top of the Pantheon. The device showed that the plane swing of the pendulum rotated relative to the rotation of the Earth. Foucault explained that the cause for gravity is the Earth’s rotation. This was not explained by the inventor of gravity, Isaac Newton.
Earth’s Rotation Day honours the first public demonstration of Foucault. This day is celebrated as the anniversary of the first display. However, there is no certainty of when, who or how this day was invented.
You can visit a local science museum and learn the complete theory behind the rotation of the Earth. You can also visit a museum where the pendulum is on the display. Learn more about Earth and its orbit on this day. Also, educate yourself, family and friends about this day and its speciality.
