Pevsner advocated the use of pure industrial materials, calling for the unity of art and science. His sculptures resemble the precision of mathematical models. Developable Surface has been painstakingly constructed by welding individual bronze rods. The straight lines curve through space, drawing the eye to the core of the sculpture, where an empty oval resides, constantly mutating as the viewer moves around. Pevsner has revealed to us what is normally invisible: that which takes place inside a geometric form.
