Cette exposition propose une travers\u00e9e historique et scientifique de plus de trois si\u00e8cles de recherches consacr\u00e9es \u00e0 la mesure, la mod\u00e9lisation et la compr\u00e9hension de la forme de notre plan\u00e8te, depuis le XVIIe si\u00e8cle jusqu\u2019\u00e0 l\u2019\u00e8re spatiale. Depuis l\u2019Antiquit\u00e9, on sait que la Terre est, dans ses grandes lignes, une sph\u00e8re. Reste une question essentielle : est-elle l\u00e9g\u00e8rement aplatie aux p\u00f4les, ou bien allong\u00e9e ? Pour r\u00e9pondre \u00e0 cette question, savants, astronomes, math\u00e9maticiens et g\u00e9od\u00e9siens ont \u00e9labor\u00e9 des mod\u00e8les th\u00e9oriques, con\u00e7u des instruments innovants et men\u00e9 de vastes campagnes d\u2019observation \u00e0 travers le monde. L\u2019exposition met en regard des sources exceptionnelles issues essentiellement des collections de l\u2019Acad\u00e9mie des sciences et de la Royal Society, t\u00e9moignant de l\u2019intensit\u00e9 des \u00e9changes scientifiques entre Paris et Londres et du r\u00f4le d\u00e9cisif de la coop\u00e9ration internationale dans la production des savoirs.<\/p>\n\n\n\n
