Initiated by the French Ministry of Higher Education and Research in 1991, the Fête de la Science is celebrating its 34th edition this year! The event, held in a number of French towns and cities, is an opportunity for the general public to discover scientific fields in a convivial atmosphere. On Saturday, October 4, 2025, the École Polytechnique invites you to meet scientists and discover their work, through fun and interactive activities.
This year, the École Polytechnique is pulling out all the stops, with a host of events designed to raise visitors' awareness of science and the progress of research. Founded in 1794 in Palaiseau under the name École centrale des travaux publics , in response to the shortage of engineers and senior executives in France, theÉcole Polytechnique has trained many engineers and military personnel over the past 220 years. Famous graduates include Henri Poincaré (mathematician), Henri Becquerel (physicist), Valéry Giscard d'Estain, Jean Tirole (economist) and André Citroën (industrialist).
Together, let's embark on an "Ocean of Knowledge", where you'll discover fascinating worlds of science, from elementary particles to clouds and beyond!
Explore topics as varied as decoding DNA, solar energy and the life of computer pioneer Alan Turing. Numerous interactive activities await you, encouraging the exchanges that have been at the heart of the Fête de la Science since its inception!
