== Models Physical And Otherwise == 
 A molecular model, in this article, is a physical model …  In this article, "molecular model" will primarily refer to systems containing more than one … 

 This is confused. 

 A "Molecular Model" is a representation, whether physical.  I think this article should treat it as such, distinguishing physical, (computer) graphical, and notional models. 

 Another problem is that "styles" (wireframe, CPK/ball-and-stick, skeletal, licorice, isosurface, cartoons, ribbons, backbone, etc.) can also be equated with "models" as they are perspectives on/representations of molecules.  —
