Abstract:

The age-old question of whether one stays driest by walking or running in the rain is addressed. In the previous literature the traveler has always been modeled by a rectangular solid. Here we consider the consequences for more well-rounded individuals, in particular, for ellipsoids. We find that, in fact, shape matters, and reach conclusions that differ from those utilizing rectangles. Indeed, we find that in the presence of a tail wind, the optimal pace for the ellipsoidal traveler is always slightly faster than the tail wind.
