Answer:

Foucault’s pendulum, which he used to show that the earth rotates.
Check out Madhur’s answer from some details.

Check out Ginkgo100’s comment for a post on the Foucault’s Pendulum at Huston Museum of Natural science. Found this video, which shows the pendulum topple pegs with time.. naaice

    Leon Foucault, the Foucault Pendulum……to prove the earth’s rotation

  2. varuns88 Says:

    1.Jean Bernard Léon Foucault

    He suspended a huge 28kg pendulum from the dome of the Pantheon in Paris to prove that Earth rotated about its axis.

  3. Tathagata Chatterjee Says:

    Leon Foucault

    He successfully demonstrated the rotation of the earth.His pendulum at Paris (1851?)was the first dynamic proof of the earth’s rotation in an “easy to watch” experiment format.

  4. Keerthi Kiran M Says:

    Leon Foucault
    Proved the rotation of the earth
    (I remember your Rangoli Maker device in Planetarium :))

  5. shivathilak Says:

    Thats the Foucault’s pendulum, named after the French physicist Léon Foucault.

    with it he proved that the earth rotates on its axis and
    proved that earts rotation is affected during solar eclipses

  6. Anu Says:

    The man is Leon Foucault. He proved that the Earth rotates about its axis.

  7. Dibyo Says:

    Leon Foucault

    French physicist best known for the invention of the Foucault pendulum, a device demonstrating the effect of the Earth’s rotation

  10. BiGFooT Says:

    Jean Bernard Léon Foucault : Focault’s most spectacular demonstration was in 1851 when he demonstrated the rotation of the Earth. He suspended a pendulum, known now as a Focault Pendulum, on a long wire from the dome of the Pantheon in Paris.

  11. vijayaraghavan Says:

    foucault. he proved the earth rotates.

  12. Atul Mathew Says:

    1-Foucault
    2-Foucalt’s Pendulum

    2 demonstrated the earth’s rotation.

  13. udupendra Says:

    Foucault’s pendulum. Rotation of the earth.

    You should have given the clue has Eco-friendly :P (Umberto Eco reference)

    The guy in the picture is Foucault and he setup the Foucault’s Pendulum to prove that the earth rotates

  18. vinod Says:

    was dat leon foucault who gave 1st physical proof of earth\\\’s rotation..?

  19. Ginkgo100 Says:

    Léon Foucault’s pendulum demonstrates the precession of the earth.

  20. Ginkgo100 Says:

    Er… to amend my answer… it demonstrates the rotation of the earth by precessing.

  21. shashank Says:

    1. Jean Bernard Léon Foucault

    Video is of the Foucault pendulum.
    Foucault built the pendulum to demonstrate the rotation of the Earth.

    Foucaults Pendulum . Earths rotation

    Leon Foucault

  24. Yash Says:

    Focault’s pendulum

  25. duriel Says:

    Léon Foucault, Foucault’s Pendulum.
    Demonstrates the rotation of the Earth.

  26. madhur Says:

    1. Jean Bernard Léon Foucault

    He invented the Foucault pendulum which gave the visual proof of the Earth’s rotation.

    Using the pendulum he demonstrated that earth rotates due to gravitational force as there is no force acting on the pendulum to make its plane of oscillation rotate or go around its own axis.

    At equator, the plane of oscillation of Foucault pendulum remains fixed relative to Earth whereas at other latitudes, the plane of oscillation precesses relative to Earth, but slower than at the pole.
