Résumé

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 25: Can we predict the behaviour of a crowd evacuating a room? To understand this phenomenon, scientists have created mathematical models for crowd motion. Crowd motion can be represented by a granular flow: each grain represents an individual, with its own movements and behaviour (similar to physical and psychological human behaviour). Crowd motion can also be represented by a liquid. Thanks to these models, scientists can reproduce various phenomena of crowd dynamics and better understand the mechanisms involved.

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.
