playing around with ctensor & the Schwarzschild metric in Maxima
what is the difference between interior and exterior Schwarzschild metrics?
also when with the exterior Schwarzschild metric the scalar curvature is zero - this cannot be right, can it?

Function: scurvature ()
Returns the scalar curvature (obtained by contracting the Ricci tensor) of the Riemannian manifold with the given metric.
