I might be making random connections, but I was reading my physics textbook (and by the way, per Bob's recommendation I referred to my textbook and found a useful explanation for Carnot engine efficiency) and there was a discussion of symmetry. It was symmetry as pertaining to Gaussian surfaces.
Now, I do use Gauss in my algorithms, but it's not this kind of Gauss. My Gauss was the Gaussian distribution from statistics; this Gauss is the same guy, but a different concept. This Gauss, specifically the Gaussian surface, is just any closed surface.
