Shepherd physics: Capturing a skittish lamb, using statistical physics

A trio of theoretical physicists have recently used ideas from statistical mechanics and probability theory to try to develop an optimal strategy for capturing a skittish lamb near a precipice. The situation that they model is an idealization of “the capture of a diffusing, but skittish lamb, with an approaching shepherd on the left and […]
