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 ...
The oldest Foucault Pendulum in Romania is located in pavilion B of the University of Oradea. It was installed in 1964 by Prof. Coriolan Rus, the then dean of the Faculty of Mathematics - Physics. (length: 14m; weight: 60 kg) "Vasile Alecsandri" National College in Galați (length: 9,92m; weight: 8 kg)
Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum. Diagrams are provided to illustrate a pendulum located at the North Pole, equator, and 45 degrees N to show how the rotation of Earth in relation to the pendulum is observed, or not, at these locations. This is not a rigorous evaluation but is ...
Jean Bernard Léon Foucault (UK: / ʒ ɒ̃ ˈ b ɛər n ɑːr ˌ l eɪ ɒ̃ ˈ f uː k oʊ /, US: / ˌ ʒ ɒ̃ b ɛər ˈ n ɑːr l eɪ ˌ ɒ̃ f uː ˈ k oʊ /; French: [ʒɑ̃ bɛʁnaʁ leɔ̃ fuko]; 18 September 1819 – 11 February 1868) was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of Earth's rotation.

Foucault's pendulum in the Panthéon of Paris can measure time as well as demonstrate the rotation of Earth. In physics , time is defined by its measurement : time is what a clock reads. [ 1 ] In classical, non-relativistic physics, it is a scalar quantity (often denoted by the symbol t {\displaystyle t} ) and, like length , mass , and charge ...
If one rotates [a heavy shell of matter] relative to the fixed stars about an axis going through its center, a Coriolis force arises in the interior of the shell; that is, the plane of a Foucault pendulum is dragged around (with a practically unmeasurably small angular velocity). [6]
The Foucault pendulum is an example from classical mechanics that is sometimes used to illustrate the geometric phase. This mechanics analogue of the geometric phase is known as the Hannay angle . Berry phase in quantum mechanics
