The grasshopper problem [PDF]

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
We introduce and physically motivate the following problem in geometric combinatorics, originally inspired by analysing Bell inequalities. A grasshopper lands at a random point on a planar lawn of area 1. It then jumps once, a fixed distanced, in a random direction.
