To Gábor Domokos, a professor at the Budapest University of Technology and Economics, an ordinary-looking rocky outcrop in the hills over Budapest is not just a respite from the busy city, but a wellspring of mathematical questions.

Best known for co-discovering the gömböc—the first convex 3D shape with just two balancing points—Domokos’ work on the geometry of pebbles has helped trace erosion on Earth and Mars.
