New mathematics-based sculpture unveils fourth dimension

Phys Org: "The stainless-steel work, a striking object of visual art, also is a mental portal to the fourth dimension, a teaching tool, a memorial to a graduate of the math department, and a reminder of the terrorist attacks of Sept. 11, 2001. The sculpture itself measures about six feet in every direction and is mounted on a granite base about three feet high in order to bring its center approximately to eye level. The sculpture, designed by Adrian Ocneanu, professor of mathematics at Penn State, presents a three-dimensional 'shadow' of a four-dimensional solid object. Ocneanu's research involves mathematical models for quantum field theory based on symmetry."
