The polymorphs of carbon graphite, fullerene, and diamond display dissimilar structures, resulting in their differences in hardness and specific gravity.
Structural differences between diamond and graphite produce profound differences between them in hardness, conductivity, density, heat capacity, and other properties.
Ten or fifteen years ago, at Katz's Delicatessen, on the Lower East Side, I chose from three or four types of salami that varied in hardness and intensity.
