Amusingly, the domain in which I used to work (physically-based rendering) primarily computes hemispherical integrals that would all conveniently be tau (the solid angle of a hemisphere). The only downside is that tau is almost always used for optical depth in scattering / Lambert-Beer’s law, but as that’s a distance tau always seemed a weird choice anyway.
mhartl: feels like you should organize Wikipedia editing parties to make alternate equations in terms of tau. https://en.m.wikipedia.org/wiki/Solid_angle would be an easy target :).
