The intuition of a surface as a "curve moving through space" is natural. The explicit parametrizations via this point of view makes it also computationally good for a calculus course, meanwhile explaining where the formulas for parametrizations come from (for instance, the parametrization of the sphere is just rotating a curve etc). Figure 1: Stokes’ theorem relates the flux integral over the surface to a line integral around the boundary of the surface. Note that the orientation of the curve is positive.
