Summary
| Description |
Français : Extrait de la Une du supplément littéraire illustré du magazine "Le Petit Parisien" en date du 2 novembre 1902, pour le cinquantenaire de la démonstration faite par Léon Foucault de la rotation de la Terre en accrochant au dôme du Panthéon de Paris en 1851 un pendule. Le pendule est libéré sans aucune autre perturbation que la gravité naturelle lorsqu'on brûle la corde. La vitesse initiale est donc nulle par rapport à la Terre, mais le pendule ne revient pas dans le même plan mais légèrement décalé démontrant ainsi la rotation de la Terre par rapport aux astres célestes. Au bout d'une heure le public, nombreux pour cette occasion, pouvait constater que le plan d'oscillation s'était décalé de 11°.
L'image est légèrement retravaillée par rapport à l'original sous Gimp pour montrer le détail du lancement et améliorer les couleurs, le contraste et la balance des blancs. English: An excerpt from the cover of an illustrated supplement to the magazine Petit Parisien" dated November 2, 1902, for the fiftieth anniversary of the demonstration by Léon Foucault of the rotation of the Earth hanging a pendulum at the dome of the Panthéon in Paris in 1851. The pendulum is released without any further disturbance than natural gravity by burning a cord. The initial velocity is nil relative to the Earth, but the pendulum does not return in the same plane but slightly offset demonstrating the rotation of the Earth relative to the celestial sphere. After one hour the public, in numbers at this event, could see that the plane of oscillation had shifted 11°. The image is slightly reworked compared to the original using Gimp to extract the detail of the launch and enhance colors, contrast and white balance. |
