Young researchers from the ChADoC association will be on hand to present workshops for young and old alike. It's an opportunity to spend a day that's as enriching as it is fun, at the heart of one of the Latin Quarter's most beautiful establishments. The Collège de France was founded in 1530. Numerous courses and lectures are given here throughout the year by the researchers who work there, and are very often open to the public. This makes it a unique place of learning.
The Collège de France awaits young and old alike this Saturday, October 11. Please note that some tours and events are by reservation only: visit the event website to find out more.
The ChADoC (Chercheurs Associés et Doctorants du Collège de France) invite you to join them on Saturday, October 11, 2025, from 10 a.m. to 6 p.m., for a festive and exciting day of science.

Laboratory visits
Prior registration essential. Preferably aged 13 and over. The Laboratoire Kastler-Brossel is a joint research unit of the CNRS, Collège de France(Institut de physique), Sorbonne University and École normale supérieure, which studies quantum physics. Here, atoms are manipulated under extreme conditions to study their behavior when isolated and close to absolute zero. Come and visit one of the experimental rooms to discover the objects researchers use to create these extraordinary conditions. The Centre interdisciplinaire de recherche en biologie (CIRB) at the Collège de France is home to numerous teams working on a wide range of themes. We invite you to visit two of these laboratories and discover how microbiologists and neuroscientists carry out their experiments.
