Anything else is just a smokescreen. > I almost replied pointing out that for a nonconservative vector field, the curl wouldn't be zero, but after reading Franz post, I see that Sergey claims curl(grad(phi)) can not equal zero, which is ridiculous, since the vector field is grad(f(x,y,z)), which immediately means it's conservative. By no stretch of the imagination is what he's stating possible, regardless of how physics works.
