The seminar “Change of scale – Change of nature” will welcome

Olivier Rey

Une question de taille

A matter of size



Olivier Rey is a researcher at the CNRS, a mathematician and philosopher, and a member of the Institute of History and Philosophy of Science and Technology (IHPST). He is the author of several essays, including Une question de taille (Stock, 2014) and Quand le monde s’est fait nombre (Stock, 2016).

The research seminar « Change of scale – Change of nature »

The generalist and interdisciplinary seminar “Change of scale – Change of nature” is organized by the CSI and the Eco-anthropology laboratory of the Natural History Museum by Léo MARIANI (MNHN, Eco-anthropology), Julien BLANC (MNHN, Eco-anthropology), Brice LAURENT (CNRS, CSI) and Jean GOIZAUSKAS (Mines Paris, CSI). Postulating that changes in scale (re)condition the nature of things as well as the observations made of them, this seminar intends to raise the issues of measurement and commensurability, of growth and degrowth.
