  "abstract": "Among Archimedes' many celebrated discoveries is a striking fact: the region of the unit sphere between two parallel planes, both meeting the sphere and separated by a distance $h$, has area $2πh$. We prove that, among connected smooth closed embedded surfaces in $\\mathbb R^3$, this property characterizes the unit sphere for a single fixed width.",
