Foucault Pendulum

This is an image of Foucault’s pendulum at the Griffith Observatory in Los Angeles. Foucault’s pendulum is basically a device that visually demonstrates that the earth rotates, the pendulum hanging from the ceiling of a standing structure is free to swing in any vertical plane. While the earth rotates the pendulum will appear to rotate relative to it yet in reality it is swinging in the same vertical plane. If you’re having a hard time visualizing it then check out this 30 seconds video on youTube, it doesn’t really explain the the concept it just demonstrates in super speed mode πŸ™‚

  5. I’ve never understood how these work. But I don’t understand why a ship doesn’t sink and why planes fly, either.
