On designing a tetrahedron-like shape that is only stable on one face.

"[I]n a preprint posted online yesterday, they have presented the first working physical model of the shape. [...] To work, it had to be engineered to a level of precision within one-tenth of a gram and one-tenth of a millimeter. But the final construction always flip-flops onto one face, exactly as it should."
