Il s’agit d’un ensemble de 54 vidéos, en langue anglaise, conçu dans le cadre d’un MOOC, intitulé “The fascination and Crystals and Symmetry”, qui a été diffusé sur la plateforme Iversity. Elles sont désormais accessibles sur la chaîne YouTube de Frank Hoffmann. Nous en donnons ici une liste, classés par chapitre, qui sont au nombre de 7 :

Chapitre 1 : Introduction to Crystals and Crystal Systems

Chapitre 2 : Crystal Systems, Fractional Coordinates, and Morphology of Crystals

Chapitre 3 : The World of Symmetry, Crystal classes and Plane groups

Chapitre 4 : Glide planes, Screw axes and Space groups

Chapitre 5 : Quasicrystals and Real Crystal Structures (in 3D)

Chapitre 6 : Metal-Organic Frameworks (MOF) and Networks
