Sauf mention contraire, les séminaires et les soutenances se déroulent à 11h30 en salle 454A du bâtiment Condorcet.


50 Shapes of Gorgonians. What the hell is Gorgonia ventalina ? An investigation by a physicist into the biological world, through cities, 3D reconstruction, beams, plates, trees, despair and happiness.

Paul Valcke (Laboratoire MSC, Université Paris Diderot, Paris and Laboratoire Borea, Muséum National d’Histoire Naturelle - Sorbonne Université, Paris).

What are shapes in nature, how do they appear, and why shapes are the way they are ? I wanted to elucidate such questions but I am a fluid mechanist. So I found an organism (gorgonia ventalina, a soft coral) which had huge interaction with mechanics. Lucky me, they exhibit very interesting shapes, with a lot of properties. How can we describe that shape ? How can we determine its properties ? How can we understand its behaviour, both in an ecological and mechanical approach ? I’ll try to give you some insight on theses questions (spoiler : I have no real answer), and talk a little bit about my process through this mess. Maybe you’ll learn few tricks, maybe you’ll avoid mistakes I have done these last two years, or maybe you will go straight into them. What is sure is that you are going to : eat (well), see nice pictures, hear some bad jokes and have a good time. Come !

Jeudi 13 Décembre 2018 à 12h30 en salle 454A.
