Robert Chambers Hoppin ‘s primary concern is what he calls “scientific expressionism”.  It combines an industrial aesthetic with visual interpretations of primal physical phenomena.  His fascinations include the beauty of both mathematical and expressive interpretation of physical phenomena.  Phenomena such as friction, pressure, velocity, light, vibration, acceleration, centrifugal force, potential energy, kinetic energy, shear forces, implosion, tension forces, torque, electrical forces and fields, magnetic forces and fields, chaotic flow, turbulence and disintegration are among the sources of inspiration.
