"visit the lab of Caltech materials ­scientist Julia Greer is to enter a realm where the ordinary rules of physical stuff don’t seem to apply. Greer designs and builds nanomaterials that behave in ways surprising to those of us who spend our days in a world where strong materials like ceramic and steel tend to be heavy, while lightweight ones are weak. When Greer controls architecture at the nanoscale, the rules change." - Todd Hoff
