WebI'll show that any smooth, simple, closed curve in 3-space must have total curvature at least 4*pi. I'll try to keep the argument as intuitive and geometrical as possible, although that's easier said than done. First, I'll show that the total curvature of _any_ closed curve (not necessarily knotted) is at least 2*pi.
