 On the academic side of the walkway is a courtyard, known as the Infinity Quad due to a striking polished stainless steel sculpture (by Jose' de Rivera, 1968, 19'×8'×2') of a continuous ribbon-like Möbius strip (commonly referred to as the infinity loop because if the sun hits the strip at a certain angle it will cast a shadow in the shape of an infinity symbol on the ground) in the middle of it; on the residence hall side is a sundial and a clock.These symbols represent time to infinity.The Quarter Mile is actually long when measured between the mobius sculpture and the sundial.
