Cet article s’intéresse à l’évolution récente d’une thématique particulière des nanosciences et nanotechnologies, les nanomachines moléculaires, au prisme d’un événement singulier dont la préparation a mobilisé les efforts des chercheurs avec une intensité particulière : la première course internationale de nanovoitures en avril 2017. Il retrace la genèse de ces objets, explique les motifs de l’organisation de la course, en raconte quelques épisodes et s’interroge sur la signification de cet événement : a-t-on affaire à un processus de gamification d’une technoscience (...) en mal de légitimité socioéconomique et de pertinence scientifique? Il montre qu’autre chose est en jeu, qui n’exclut pas la production de connaissances mais l’inscrit dans une nouvelle manière – technophanique – de réaliser des expériences. (shrink)

This article explores the crucial moments of scientists’ research activities when they decide to shift to a radical new domain or to perpetuate a project. We introduce what we have called the “respiration model” which describes and analyses key cognitive components which occur in this complex process. Respiration either privileges epistemic expectations which are rooted in socio-cognitive metrics of “concentration” or in a functionality-multiple horizon context which we refer to as “extension”. The respiration model accords particular attention to the elements (...) curiosity and synergy in science. (shrink)

Advertisements for high-technology products and services visualize processes and phenomena which are unvisualizable, such as globalization, networks, and information. We turn our attention specifically to the case of nanotechnology advertisements, using an approach that combines visual and sonic culture. Just as phenomena such as complexity and networks have become established in everyday discourse, nanotechnology seizes the social imaginary by establishing its own aesthetic conventions. Elaborating Raymond Williams’ concept of structures of feeling, we show that in visualizing nanotechnology, its stakeholders employ (...) spaces, verbs, and objects of feeling. These favorable nanotechnology structures of feeling are woven into the social imaginary, recursively producing the reality they describe. (shrink)
