Theory Meets Experiment

A colleague presents experimental evidence related to a phenomenon under theoretical study. The evidence is a preprint by four authors from the National Bureau of Standards, discussing a material with an icosahedral symmetry. Initially thought to be short-range order, it is revealed to be long-range icosahedral order. The speaker recognizes the diffraction pattern, matching it with their own model, leading to a significant realization.
