English: "Infinity Ring" (2005) continuum sculpture by Charles Sherman, sand cast aluminum, hand brushed 14" x 9" x 3" This three-dimensional, three-revolution infinity ring form was inspired by by the two-revolution Mobius Strip, first formulated by the 19th century German mathematician and astronomer, A. F. Mobius. The circular planes that form the ring have no beginning and no end. The bottom side becomes the top side and the inside becomes the outside. This continuum form was created using the same principles that Dutch graphic artist M.C. Escher used to explore infinity and the reversal of positive and negative forms in space.
