You cracked a puzzle about the structure of strange crystals called approximants that had gone unsolved for eight years. Tell us more.
Sven: Approximants are related to quasicrystals, which are ordered atomic structures but with symmetries that were believed to be impossible – for example, 5-fold symmetry. The approximants we studied have 5-fold and 10-fold symmetry.
