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.

2017年5月7日 · The four-story Foucault pendulum at the Franklin Institute has now been swinging for more than 80 years. It was installed by 11 people, who worked vigilantly to keep the 85-foot wire from ...

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.

This is a list of Foucault pendulums in the world: Artistic rendition (highly exaggerated) of a Foucault pendulum showing that the Earth is not stationary, but rotates.

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 …

The Franklin Institute is a science museum and a center of science education and research in Philadelphia, Pennsylvania. It is named after the American scientist and statesman Benjamin Franklin. It houses the Benjamin Franklin National Memorial.

The 4-story Foucault’s Pendulum at The Franklin Institute is designed to demonstrate the nature of the Earth’s rotation. Over the course of a day, the instrument swings in a constant direction; however, as the Earth turns underneath it, the pendulum appears to move in a circular direction.

2013年3月18日 · Foucault’s Pendulum isn’t just a scientific demonstration; it’s a philosophical lesson in life’s relativity. The center of the earth can be found at the intersection of 20th Street and Benjamin Franklin Parkway in Center City, Philadelphia. The exact center is inside The Franklin Institute, in the stairwell.

2025年1月24日 · Foucault pendulum, relatively large mass suspended from a long line mounted so that its perpendicular plane of swing is not confined to a particular direction and, in fact, rotates in relation to the Earth’s surface. In 1851 the French physicist Jean-Bernard-Léon Foucault assembled in Paris the
