“But Wallace didn’t just talk *about *math. He structured his work with it. In a 1996 *Bookworm* interview with Michael Silverblatt, Wallace explained that he modeled *Infinite Jest *after a Sierpinski Gasket, a type of fractal in which a triangle is infinitely subdivided into smaller triangles using the midpoint of its borders. Pressed by Silverblatt on why he chose such a formation, Wallace elaborated: “Its chaos is more on the surface; its bones are its beauty.”
