Abstract. A basic arbitrariness in the determination of the topology of a manifold at the Planck length is discussed. An explicit example is given of a `smooth' change in topology from the 2-sphere to the 2-torus through a sequence of non-commuting geometries. Applications are considered to the theory of D-branes within the context of the proposed M(atrix) theory.
