Is the surface any good? After five years of hard toil, George L-Legendre, an esteemed theorist of mathematical surface ontology and the architect of a large surface-inspired infrastructural project, ponders the usefulness of the three-dimensional surface in writing, teaching, and practice - and offers a couple of tips. George L-Legendre is Unit Master of Dip 5. From 1995-2000 he was Assistant Professor at the Harvard GSD. Since 2003 he has been visiting professor at Princeton University. His practice, IJP Corporation, is building infrastructure in Asia and Europe.
