Séminaire PMMH - François Graner (Laboratoire MSC & Université Paris-Cité))
Should we forbid scientific research ?
Economic growth is not sustainable. Research, which is one of the pillars of economic growth, contributes to current environmental disasters and social inequalities. Conversely, research is often presented as part of the solution : many institutions and actors call for more funding of research to fuel so-called "green growth". We will argue that this attitude combines a headlong rush similar to the coyote who does not notice the absence of firm ground under his feet, and an ostrich-like denial like burying one's head in the sand.
In fact, green growth' minor version promises to simultaneously pursue growth and decrease carbon emissions. It is short-sighted, and we will propose tools to analyze its "false good ideas". Conversely, the major version promises to pursue growth while decreasing the overall consumption of energy and matter resources as well as environmental impact. This is naive, and faces obstacles linked with thermodynamics principles.
We will examine alternative suggestions based on accepting limits, and giving up the race for power. We will discuss the definition, conditions and consequences of "degrowth". The obstacles it faces are hard but not impossible to overcome, since they originate from humans rather than from thermodynamics.

Physics of animal collective behavior : interactions with one another and their environment
The breathtaking aerial displays and mesmerizing formations of birds, fish shoals and the thunderous gallop of hundreds of horses exemplify captivating group behaviors in nature. Traditional measurement methods fall short in capturing these intricate behaviors arising from simple individual interactions, (…) -

Discharge Flow of a Granular Media from a Silo : Experimental investigations and continuum modeling
Silos are widely used in the industry. While empirical predictions of the flow rate, based on scaling law, exist for more than a century, recently advances have been made on the understanding of the control parameters of the flow. In particular using a continuum model together with a visco-plastic frictional (…) -

Coarse-grained models for schooling swimmers in fast flows
The beautiful displays exhibited by fish schools and bird flocks have long fascinated scientists, but the role of their complex behavior remains largely unknown. In particular, the influence of hydrodynamic interactions on schooling and flocking has been the subject of debate in the scientific literature. I will (…) -

Flowing through a world of patterns
Why is there so much structure, order and texture to life and nature, rather than a featureless expanse ? From microscopic snowflakes to dried mud and vast river networks, pattern formation gives rise to systems of extraordinary intricacy and beauty. Understanding how a system spontaneously selects its overall (…)
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
