Experiments Explain Why Some Liquids Are ‘Fragile’ and Others Are ‘Strong’

800px-Glass_is_Liquide.jpg

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...
