La Preuve Par l'Image 2019




This exhibition is a response to the dual challenge of using images rather than words to "speak" about research and engaging in a dialogue with the public. Beyond images' pure beauty, they are also a research and investigation tool which enables scientists to decipher their own results. Photographs taken using all techniques - from cameras to drones and microscopes - offer another vision of research which can be surprising, unexpected, indecipherable and sometimes essential.

Titles, legends and technical descriptions complete this approach which takes us deep into the fascinating world of scientific research.

Nearly 200 people from laboratories took part in the "La preuve par l'image" (Proof by Images) exhibition for the first French edition of this photo competition.

A jury made up of image and science professionals selected twenty winners from a wide variety of disciplines.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
