La phénoménotechnique questionnée par la médiation. L'exemple du showroom du Larsim

The purpose of this article is to present a space of mediation developed by the astrophysicist Vincent Minier and the philosopher Vincent Bontems at the Commissariat à l’Énergie atomique et aux Énergies renouvelables. This room, called “showroom”, promotes the spatial telescope Herschel and its discoveries. Initially, the creators wanted to set up a place of prospective in digital mediation and of reflection about different concepts as “phenomenotechnology”, “mechanology” or “object-image” in astrophysics. However, the showroom became a guardian of the telescope’s memory without a clear mediation approach. I will first explain the origin of this space and give a description of the different machines presented there. Then, I will propose a pedagogical experience to redefine an explicit line of mediation in order to work on these concepts with pupils.
