Weyl invariance can be used as a principle for constructing not only conformally invariant massless physical theories, but also massive, partially massless and gauge invariant ones. We present "Tractor Calculus"--which arose in conformal geometry--as a description of Weyl invariance in physics. We use this calculus to give new descriptions of a range of fundamental physical theories.
