Abstract
In the simplest case “Objective Structures” are structures like carbon nanotubes, graphene and phosphorene in which each atom sees the same environment. We comment on their striking prevalence in nanoscience, materials science and biology and also explain why they arise in a natural way as distinguished structures in quantum mechanics, molecular dynamics and continuum mechanics. The underlying mathematical idea is that the isometry group that generates the structure matches the invariance group of the differential equations. Their characteristic features in molecular science imply desirable features for macroscopic structures. We illustrate the latter by constructing some “objective origami” structures.
