Why some liquids are 'fragile' and others are 'strong'
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 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.
