Only recently has it become possible to accurately "see" the structure of a liquid. Using X-rays and a high-tech apparatus that holds liquids without a container, a physicist at Washington University in St. Louis has compared the behavior of glass-forming liquids as they approach the glass transition. The results are the strongest demonstration yet that bulk properties like viscosity are linked to microscopic ones like structure.
