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)
The Smithsonian inducted Vera into its Resident Associate Program in October 1972 as their first artist and commissioned her to paint the Foucault Pendulum, which still hangs in their offices today. The institute launched the program "A Salute to Vera: the Renaissance Woman" at the Museum of History and Technology . [ 12 ]
The telescope was built at the Secretan Company of Paris, and its construction was supervised by the celebrated French physicist Léon Foucault. [5] Foucault is known for the pendulum experiment that demonstrated earth's rotation [4] and for the knife-edge test of telescope optics. [10]
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.
The Foucault pendulum, demonstrating the Earth's rotation. The length of the pendulum's cable is over 60 feet (18 m) long. Cullen Hall of Gems & Minerals, featuring a large exhibit of over 750 crystallized mineral specimens and rare gemstones. Lester and Sue Smith Gem Vault, showcasing some of the most exquisite finely cut gems in jewelry.
The planetarium also housed a thirty-five foot long Foucault pendulum [11] and a ten-inch, Siderostat-type, refractor telescope (now the second largest of its type). [12] The planetarium also housed the Miniature Railroad and Village from 1954.
Foucault published two papers in 1852, one focused on astronomy with the weight free to move on all three axes (On a new experimental demonstration of the motion of the Earth, based on the fixity of the plane of rotation) [8] and the other on mechanics with the weight free to move on only two axes (On the orientation phenomena of rotating bodies driven by a fixed axis on the Earth's surface.
