SUMMARY:Inverting Algae and Shape-Shifting Droplets - Pierre Haas (Univers
 ity of Cambridge)
DTSTART:20180201T130000Z
DTEND:20180201T140000Z
UID:TALK100174@talks.cam.ac.uk
CONTACT:Anne Herrmann
DESCRIPTION:This talk is divided into two parts: first\, I shall describe 
 a generalised elastic theory for the inversion process of the green alga V
 olvox. I shall analyse the mechanics of type-A inversion in Volvox carteri
 \, and interpret mechanically the arrest of inversion in mutants and chemi
 cally treated embryos. Second\, I shall give an update on our work on shap
 e-shifting droplets (which flatten into a host of polygonal shapes upon co
 oling)\, and discuss the competition between geometry and topology that ar
 ises in the polyhedral stages intermediate between the spherical and flatt
 ened droplet shapes.\n
