Foucault pendulum - Wikipedia
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
How Does Foucault’s Pendulum Prove the Earth Rotates?
On February 3, 1851, a 32-year-old Frenchman—who’d dropped out of medical school and dabbled in photography—definitively demonstrated that the Earth indeed rotated, surprising the Parisian...

傅科擺 （英語： Foucault pendulum、Foucault's pendulum），是依據法國物理學家 萊昂·傅科 命名的，用以證明 地球自轉 的一種簡單設備。 雖然人們長久以來都知道地球在自轉，但傅科擺第一次以簡單的實驗予以證明。 今天，它在許多科學博物館和大學內是很受歡迎的展品 [1] 這個實驗的裝置包括一個高大的、在任意垂直平面上 振盪 的 單擺。 單擺擺動的方向會因為地球本身的週日轉動而改變。 這是因為單擺的擺動平面，像 陀螺儀 一樣，當地球轉動時仍會在空間中保持固定 …

Foucault's Pendulum and the Coriolis Force - University of …
In 1851, the French physicist Jean Léon Foucault hung a 67-meter pendulum from the dome of the Panthéon to demonstrate the rotation of the earth for the first time. The wire was attached to the ceiling through a universal joint so it could rotate freely about its axis.
Léon Foucault | Inventor, Experimenter, Demonstrator | Britannica
Léon Foucault was a French physicist whose “Foucault pendulum” provided experimental proof that Earth rotates on its axis. He also introduced and helped develop a technique of measuring the absolute speed of light with extreme accuracy.
Léon Foucault - Wikipedia
Foucault achieved the demonstration by showing the rotation of the plane of oscillation of a long and heavy pendulum suspended from the roof of the Panthéon, Paris. The experiment caused a sensation in both the learned and popular worlds, and "Foucault pendulums" were suspended in major cities across Europe and America and attracted crowds.
Foucault's Pendulum - The Franklin Institute
The Franklin Institute’s four-story Foucault’s Pendulum mimics an experiment undertaken by French physicist Jean-Bernard-Leon Foucault early in 1851. The experiment proved the nature of the Earth’s daily rotation around its axis. The fact that the Earth is spinning and the pendulum is swinging creates this interesting effect.
The Foucault pendulum - UNSW Sites
In 1851, Jean-Bernard-Leon Foucault suspended a 67 metre, 28 kilogram pendulum from the dome of the Pantheon in Paris. The plane of its motion, with respect to the earth, rotated slowly clockwise. This motion is most easily explained if the earth turns (anticlockwise if viewed from the Northern hemisphere, clockwise from the South).
Then, in 1851, a young French physi-cist stunned the world. Léon Foucault showed that a simple pendulum, through its continuous periodic swinging, would accumulate the tiny effects of the earth’s rotation. Witnessed by observers at the Panthéon in Paris, the plane of motion.
