The secrets of matter
Come explore the secrets of matter, from elementary particles to innovative materials and living matter, through atoms and molecules.

Discover the amazing properties of all these components and how to study or manipulate them to understand our Universe, create light, produce energy, or obtain new drugs. Through demonstrations, laboratory visits, conferences or shows, explore the periodic table of elements and their properties, dive into into the quantum world, or visualize atoms with high resolution microscopy, …. Matter is full of surprises!
