Time, distance, weight, heat, pressure, etc... Measurements are ubiquitous. But how have they been developed and disseminated over time? What instruments and devices have been devised to produce ever more accurate measurements? How far is it possible to push this precision, and to what end?
On the occasion of the 150th anniversary of the Metre Convention, we will look back with four specialists at the immense progress made in the precision and standardization of measurements, and explore the new challenges facing the measurement sciences today.
In this episode of "Keys to understanding", hosted by Mathieu Rouault (journalist, Grand Labo), we'll look back at the past and present challenges facing metrology, with :
Gérard Berry, member of the Académie des sciences, professor at Collège de France
Sandrine Bony, member of the Académie des sciences, director of research at CNRS
Céline Fellag, Head of Executive and Meetings Office, BIPM
Jean-Marc Bordy, research engineer at CEA, winner of the LNE 2024 research prize
