“I’d grown up inside vectors, lines and lines athwart lines, grids–and, on the scale of horizons, broad curving lines of geographic force, the weird topographical drain-swirl of a whole lot of ice-ironed land that sits and spins atop plates. The area behind and below these broad curves at the seam of land and sky I could plot by eye way before I came to know infinitesimals as easements, an integral as schema.”
