Inversion Principle: MP.MQ=MR²

"From the large body of algebra available to the lover of visual maths, JP borrows one equation only. His chosen equation describes a two-dimensional transformation called inversion, which involves a wholesale reflection of figures about a circle. JP methodically applies the principles of inversion to various primatives (spheres, cylinders, cones, cross-caps and so on) and explores the striking manifestations of their transformation in space ..... the sheer beauty and material sophistication of his sculpture, which involves card cutting and plaster-casting, cannot be accounted for on the basis of mathematics alone."
