About this Abstract
Meeting 2017 TMS Annual Meeting & Exhibition
Symposium The John Cahn Memorial Symposium
Presentation Title Quasi-history of Quasi-crystallinity
Author(s) Olivier Hardouin Duparc
On-Site Speaker (Planned) Olivier Hardouin Duparc
Abstract Scope John Cahn contributed to the birth of quasicrystals because he believed in the observations made by Dan Shechtman about the existence of an icosahedral metallic phase with long-range orientational order up to the point of writing with Shechtman, Ilan Blech and Denis Gratias a paper which was successfully submited to Physical Review Letters. Under the sign of the icosahedron I’ll start with Plato’s physical chemistry in his Timeaus, to Kepler’s 1595 planetary model and to the invention of the mathematical quasiperiodic functions in order to illustrate some relations between mathematics and physics which do not have to be simple.
