I was able to see further than my complementary because i stood on the shoulder of a giant; (I. Newton). Since physics advances by a series of approximations, it is foolish to say at any stage that the process of successive approximation is over. Therefore when one comes to replace Newtonian Mechanics by Relativistic mechanics, one cannot claim infallibility for the theory of special relativity, but must always admit that it in turn can be replaced at any time by a new theory, provided the new theory is in better agreement with the experimental results (W.G.V. Rosser). It is my great pleasure to engrave the name of Professor S.X.K Howusu which came up with a profound discovery in his book entitled: The METRIC TENSORS FOR GRAVITATIONAL FIELDS AND THE PRINCIPLES OF RIEMANNIAN THEORETICAL PHYSICS [Howusu, 2009]. He introduced by postulation three metric tensors for all space times in nature in Einstein spherical polar co-ordinates. These metric tensor can be transformed from spherical polar co-ordinate into all other orthogonal Curvilinear Coordinates to open the way for the development of the corresponding Riemannian Geometry and application to theoretical physics.
