Science trims XX of them
Today, only 30% of researchers and 27% of engineers are women. That share falls
even further in fields like physics, engineering, and mathematics, even though these are often pitched as fields with bright futures. Before they turn 16, most girls have already abandoned the idea of a scientific career. To convince them that research can be a thrilling profession too, we must break down the gender stereotypes still in play and offer more accessible, inspiring role models embodied by today's women scientists.
For this reason, CNRS and the Femmes & Sciences association have chosen to showcase, through imagery and words, the talents
of women in science by launching the program “La Science taille XX elles,” built around a photography exhibition by Vincent Montcorgé that highlights women's place in science and promotes scientific careers among young women, accompanied by meetings and intimate exchanges with the project ambassadors.

Creating the Crystal: A Journey Between Art and Science
Crystals have long fascinated humanity — for their perfection, their beauty, their physical or chemical properties, or for the virtues people hoped they would bestow. First found in nature as minerals, inorganic or organic, crystals have spurred extensive research. Today, a wide range of synthetic efforts aims to reproduce nature’s masterpieces, to create new materials, and to unlock unprecedented properties that meet society’s evolving needs and the exploration of new realms.
You will discover how crystals, in all their forms and at various scales, figure in a multitude of everyday tools and objects, and how they help illuminate how living systems work or misfunction. Then, beyond technique and innovation, you will witness a meeting, a sensitive and reflective dialogue between two laboratories: the scientist’s and the artist’s — between research, industrial advances, and artistic creation. You will enter the worlds of several artists inspired by science, matter, growth, and the “control” of chance. The works of Ada Yu (ADA), Léa Barbazanges, Vincent Gontier, and Robin Guittat will weave a poetic and aesthetic dialogue with the long history and current trajectory of research into crystalline synthesis.

Magnetic Resonance in all its facets
Sorbonne University and the CNRS open the doors to the Nuclear Magnetic Resonance (NMR) Platform in Paris‑Center. This facility houses nine NMR spectrometers linked to ultra-strong magnetic fields—up to 300,000 times stronger than the Earth’s field. Such fields are only possible with superconducting materials kept at -269°C using cryogenic fluids. It’s a sophisticated, ultra‑powerful analytical tool at the atomic scale. It enables the study of tiny or large molecules, as well as materials, whether crystallized or disordered, in all states: liquid, solid, or gas. The technique covers a broad range of disciplines: chemistry, biology, physics, ..., and is also employed in industry and for other applications, including medical imaging (MRI) and fraud detection. A guided tour of the platform will be offered, followed by a brief introduction to this analytical method. In a second part, interactive demonstrations using everyday products will illustrate the instrument’s performance.
This event will take place at Tower 32-33 on Sorbonne University’s Pierre and Marie Curie campus. Find us on the Platform site: http://rmn.sorbonne-universite.fr

Qats Game — Quantum Mechanics Game Board
The aim of this game is to build intuition about the quantum formalism and make it easier to grasp. Its rules mirror the so‑called "rules" of quantum mechanics, letting players manipulate quantum objects as they play—without them explicitly realizing they are performing quantum operations. The goal is to use the game to convey key notions and reflexes of quantum mechanics without forcing formal explanations. We’ve observed that people, in the realm of social games, can learn and master complex rules with ease. The idea here is to apply that principle: align the game’s rules with the "rules" of quantum formalism (such as the effect of measurement and the consequences of entanglement) so the audience develops quantum intuition without being taught the formalism directly.

Escape room "The Quantum Cure"
A new, unstoppable virus is sweeping the globe, threatening to wipe out humanity in record time. Australia, with a reported 99% mortality rate, is already fully infected. In a bid to curb this medical catastrophe, a handpicked team of the world’s leading scientists—doctors, virologists, biologists, computer scientists and physicists—has been assembled to craft the perfect antidote to destroy the pathogen before it can spread further. Yet, just as the team was about to publish their findings, they are mysteriously found dead.
That is why health authorities have summoned the QICS (Qualified Intelligence Center of Secrets) and have selected you, among the department’s top agents, to lead the investigation and uncover the research results.

The forgotten women of science
He For She will present, as part of the science festival, an interactive activity designed to be accessible to all, spotlighting the great women scientists who have been forgotten throughout history.
Our aim is to raise public awareness about the role of women in science, the gaps in recognition, and the substantial body of work by women that has long been overlooked or attributed to others.
The main feature will be a playful, participatory quiz titled “Who Really Shouldered This Discovery?” Participants will match various discoveries, inventions, or scientific breakthroughs to the rightful female researchers. Through this engaging format, we want to highlight how many major advances were achieved or co-authored by women scientists who are frequently missing from traditional historical narratives.
To keep the activity dynamic and accessible to diverse audiences, we will offer several supports: game cards, explanatory posters, scientific anecdotes, discussions with association members, and potentially mini-challenges or symbolic rewards for participants. We also aim to showcase scientists from a variety of fields to illustrate the breadth of women’s contributions across the sciences.
The He For She association will run this activity on Thursday afternoon for visiting school groups on the campus as part of the science festival. This format will enable direct engagement with students and provide a playful way to raise awareness about equality and representation in scientific environments.
Participation requirements:
• Target audiences: 3–6 years, 6–11 years, 11–15 years, 15–18 years, 18–25 years, 25 years and up

Mineral Daydreams — a Sonic Nap
Stone organs carved from limestone, marble, and volcanic rock are activated live: struck, brushed, and coaxed to resonate. The voice sometimes joins in, a breath inviting the rocks to tell their story. These stones, formed over millions of years, speak to you for just a few minutes. Let yourself be carried by the deep resonances of the Earth.
In collaboration with Erwan Martin, geology professor and researcher at Sorbonne University.
