Yes, together with special and general relativity stuff, like the Lorentz matrix etc. So that one can write some tensor in a local inertial frame, like T^\mu\nu = diag(rho*c^2, p, p, p) and get it automatically transformed into some other frame using the Lorentz transformation: T^\mu\nu = (rho + p/c^2)u^\mu u^\nu + p g^\mu\nu see here: http://certik.github.com/theoretical-physics/book/src/fluid-dynamics/general.html#perfect-fluids it'd be nice to play with such things in sympy.
