As the name suggests, this building houses the Mathematics Department. This former home of the Engineering School once featured a full-sized steam locomotive inside. The area around Mathematics Hall is known as the site of the Battle of Harlem Heights. During the American Revolution, George Washington’s troops staged an important offensive against the British troops here. Though inconclusive, it revived American morale after defeats in Long Island and at Kip’s Bay. A plaque on the Broadway side of the building commemorates the battle.
The mathematics and science library here have two distinct and separately maintained collections. The mathematics holdings cover all aspects of pure mathematics, including algebra, number theory, geometry, topology, mathematical statistics, and probability. The library currently subscribes to 250 international mathematics serials. The science collection consists of general and multidisciplinary materials in such areas as the history of science and technology, older scientific periodicals and publications of academies and learned societies.
