On 10 March 2026, the Collège Sismondi played host to the latest TecDays, an initiative organised by the Swiss Academy of Engineering Sciences (SATW) aimed at bringing young people closer to science and technology.  Professionals from a wide range of backgrounds, including CERN, took part in this event by sharing their passion and demonstrating how maths, computer science and the natural sciences have real applications in everyday life.

A range of modules were open to the pupils throughout the day. For its part, CERN organised workshops on liquid nitrogen, introducing participants to the phenomenon of superconductivity. Handling the apparatus with care, pupils were able to observe the Meissner effect, where a magnet levitates above a superconducting material.

The aim was not only to demonstrate the scientific phenomenon itself, but also to challenge certain preconceptions, namely that physics does have practical applications and that scientists are not distant figures hidden away in shadowy laboratories. Direct contact with scientists helps break down stereotypes, humanise these professions and awaken vocations.  

The event also plays an important role in promoting equal opportunities, by enabling boys and girls alike to engage with science, technology, engineering and mathematics (STEM). Initiatives like TecDays help to bridge gaps and to encourage all schoolchildren to see themselves in this kind of career. Particular efforts were made to get girls involved, as they are still too often left in the background in hands-on activities.
