La figure de la Terre: Un débat franco-anglais (XVIIe-XXIe siècle), an exhibition running at the Bibliothèque Mazarine in Paris from 1 April to 20 June 2026.
This exhibition offers a historical and scientific journey through more than three centuries of research devoted to measuring, modeling and understanding the shape of our planet, from the 17th century through to the space age. Since ancient times, we’ve known that the Earth is, broadly speaking, a sphere. The key question was whether it was slightly flattened at the poles or elongated. To answer this question, scientists, astronomers, mathematicians and geodesists have developed theoretical models, designed innovative instruments and conducted vast observation campaigns around the world. The exhibition features exceptional sources drawn mainly from the collections of the Académie des Sciences and the Royal Society, testifying to the intensity of scientific exchanges between Paris and London and the decisive role of international cooperation in the production of knowledge.
France seems to have quite a lot of map-related programming lately.
