Dr. Spaepen presents a short article on determining the structure of liquids and comments on recent work that has gotten closer to validating models with experimental data. He notes that to this point, attempts to describe liquids as disordered crystals have failed and describing them as dense gases is too complex. The favorite approach thus far has been to describe a liquid as a dense packing of tetrahedral building blocks. A persistent challenge for condensed matter physicists has been to find a simple structural description of liquids, akin to the periodicity of crystals and sparsity for gases. The liquid phase is now accepted as a well-defined phase, not merely a heavily defective crystal or a random assembly of micro-crystals, so work is on-going to characterize liquid structure.
