COLLOQUIUM TODAY!!: A Brief History of Glass Michael Thorpe, ASU Thursday, January 16th, at 3:15p.m. Bateman Physical Sciences Building F-Wing, Room 101 Light Refreshments at 3:00 p.m. Abstract It is just over eighty years since the publication of perhaps the most famous paper in glass structure, viz. The Atomic Arrangement in Glass by Frederick Zachariasen. In the early days, models were hand-built with plastic units and had free boundary conditions. Today, very much larger computer models have periodic boundary conditions. I recount the progress that has been made, and discuss the current agreement between models and experiments and continuing controversies [1]. Recent synthesis and atomic imaging by TEM and STM of vitreous silica bilayers promise to facilitate some of the unsolved issues relating to network glass structure [2]. [1] M.F. Thorpe and A.
