Abstract:
Tête de Moine should be enjoyed in the form of cheese
«flowers»:
thin slices rolling up with complex convolutions, which are obtained simply by
scraping the cheese with a rotating blade (the «girolle»). What is
the physical mechanism at play in this morphogenesis that produces complexe
shapes out of a simple process?
We will see that it is related to a deep property of the geometry of surfaces,
which has consequences on many other physical objects around us. I will also
show how it can be used to imagine active shape-morphing surfaces.
