W.H. Zachariasen - the melody lingers on

Abstract “The Atomic Arrangement in Glass” is only a minor part of the extensive contributions of W.H. Zachariasen. Yet, this brief incisive, intuitive theoretical paper. published in 1932 when Zachariasen was only 26 years of age, may be as infuential as his more widely acclaimed works on atomic radii, crystal structure, X-ray theory and practice, and the chemistry of transuranium elements. Speculation regarding the factors that piqued Zachariasen's interest in glass will be offered. Some of the many ways in which “The Atomic Arrangement in Glass” has influenced thinking about glass structure over the past half century will be explored. Within his paper, W.H. Zachariasen presented topological conditions (Zachariasen's Rules) necessary for easy glass formation. Many modern workers find topology of amorphous atomic networks a fascinating subject. Thus, it seems in order to attempt a generalization of Zachariasen's Rules in order to permit their application to some glass forming systems that were not known in 1932.
