Calculations in this theory can be simplified in a manifold named for Minkowski. This theory includes the "pole in the barn" and "twin" paradoxes, and it predicts length contraction and time dilation. This theory assumes the (*) speed of light to be constant in all reference frames; that fact can be used to derive E = mc2 . For 10 points, name this theory, proposed by Einstein before its "general" counterpart.
