Livre
Paru le 31 octobre 2018 aux éditions Odile Jacob : Les Lois d'échelle, La physique du petit et du grand
Réalise-t-on bien que derrière l’infinie diversité des stratégies du monde vivant se cachent des lois d’une extrême simplicité ?
Qui penserait que le colibri et le condor, la souris et le tyrannosaure, ou encore le poisson rouge et la baleine partagent des lois physiques communes ?
Ces « lois d’échelle », aussi simples qu’élégantes, transcendent les dimensions pour donner accès à des principes essentiels.
Tous les objets volants, par exemple, obéissent à une loi simple qui lie leur vitesse à leur masse : un moineau vole moins vite qu’un Airbus,
mais tous deux obéissent à la même loi d’échelle. Il en va de même de la souris et de l’éléphant, si l’on compare leur poids et leurs besoins énergétiques.
Car si le monde animal est du ressort de la biologie, il se conforme aussi à des lois physiques et géométriques incontournables.
Ce livre novateur invite à voir la nature d’un autre œil, plus attentif à la dimension des choses et à leur forme qu’à leur mise en équation. Cette méthode d’analyse à la portée de tous devrait faire de nombreux adeptes.

Videos
Freezing drop impact :
-
A water drop impacts a cold surface and freezes as it spreads. The following video illustrates this experimental study :
See "Retraction and freezing of a water film on ice" [PDF] for more informations.
Jet from hollows :
-
When a large bubble is introduced in a fluid, a jet can develop in the bubble. This jet can be strong enough to perforate the bubble and shoot out above the free surface. A similar jet exhibits when a cavity is shaped at the free surface a liquid. The following video illustrates this experimental study :
See "Liquid jet eruption from hollow relaxation" [PDF] and "Large bubble rupture sparks fast liquid jet" [PDF] for more informations.
-
The following video presents the same system from a purely artistic point of view, the experimental sequences are presented using a soundtrack from the band "Team Ghost" :
This video has been awarded as part of a communication initiative around this project.
From turbulent mixing to gravity currents in tilted tubes :
-
Buoyant mixing of a lighter fluid rising spontaneously into a heavier miscible fluids in a tube at variable tilt angles is presented in the following video :
See "Buoyant mixing of miscible fluids in tilted tubes" [PDF] for more informations.
