New Perspective On Relativity, A: An Odyssey In Non-euclidean Geometries - Lavenda, Bernard H (Univ Degli Studi Di Camerino, Italy)

Starting off from noneuclidean geometries, apart from the method of Einstein's equations, this book derives and describes the phenomena of gravitation and diffraction. It presents a historical account, exposing the missing link in Einstein's construction of the theory of general relativity.
