The Science Festival 2026 is back from October 2 to 12 with thousands of free activities held all across France to bring science closer to everyone. This 35th edition, under the theme "Savory Science", invites audiences to explore the links between food, taste, health, the environment and research through workshops, encounters, tours and a multitude of hands-on experiences accessible to all. In Île-de-France, the towns of Yvelines are also taking part in this surge of scientific culture, giving families, students and the curious the chance to meet the people who drive research and to discover science from a practical perspective.
Nestled in the heart of Saint-Quentin-en-Yvelines, Trappes boasts a history that predates its modern development by centuries. Occupied since the Paleolithic era, the area evolved into a medieval village before joining the royal domain. Under Louis XIV, it played a key role in the expansive hydraulic network designed to feed the fountains of the château de Versailles, notably via the étang de Saint-Quentin. In the 19th century, the arrival of the railway transformed the commune into a major railway hub. To this day, Trappes preserves that identity while continuing to evolve within the Saint-Quentin-en-Yvelines metropolitan area.
With its historic heritage, its railway past and its wide natural spaces, Trappes offers a compelling backdrop for exploring science from multiple angles. The Fête de la Science makes it possible to tackle a variety of topics by linking them to the region’s history, environmental questions, and the innovations shaping our daily lives. It’s also a chance to discover the town from a different perspective, taking time to appreciate what makes it distinctive and the initiatives that help spread knowledge. The activities staged during the festival invite the public to observe, understand, and exchange ideas in a spirit of curiosity and sharing.
Yum, that tastes great! Yuck, that doesn't taste good!!
How many times have we heard those words? Honestly, I’ve stopped counting ages ago. But really, why is it a good thing, and why don’t we like some flavors? What are we actually eating? Where do our foods come from? How should we cook them? Traditional cuisine or molecular gastronomy?
Come discover, through our experiments, the well-kept secrets of our 'Savantes Flavors'.
