SUMMARY:Atomistically inspired origami  - Prof Richard D. James\, Departme
 nt of Aerospace Engineering and Mechanics\, University of Minnesota

DESCRIPTION: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 nanoscie
 nce\, materials science and biology and also explain why they arise in a n
 atural way as distinguished structures in quantum mechanics\, molecular dy
 namics and continuum mechanics.  The underlying mathematical idea is that 
 the isometry group that generates the structure matches the invariance gro
 up of the differential equations.\nTheir characteristic features in molecu
 lar science imply desirable features for macroscopic structures.  We illus
 trate the latter by constructing some “objective origami” structures.\
