[4][2] Richeson is the author of the book Euler's Gem: The Polyhedron Formula and the Birth of Topology (Princeton University Press, 2008; paperback, 2012), on the Euler characteristic of polyhedra.
[6] His second book, Tales of Impossibility: The 2000-Year Quest to Solve the Mathematical Problems of Antiquity (Princeton University Press, 2019), concerns four famous problems of straightedge and compass construction, unsolved by the ancient Greek mathematicians and now known to be impossible: doubling the cube, squaring the circle, constructing regular polygons of any order, and trisecting the angle.
