A beautiful realization is in the physics of thermalized 2D metamaterials, such as graphene, where thermal effects already set in at microscopic length scales. This opens the way to generating materials of any required modulus from one source material in different geometrical regimes and to the manipulation of nano and micromechanical systems by geometry, rather than external fields.Mark BowickMark Bowick was born in New Zealand, obtained his B.Sc.(Hons) from the University of Canterbury (New Zealand)
