The Mathematical Theory of Relativity

THE second edition of Prof. Eddington's book is a reprint of the first edition with the addition of a number of supplementary notes and one or two corrections. Some of the notes are designed to remove misunderstandings such as are constantly met with in debates on the relativity theory. Others give alternative mathematical treatments of various points, as, for example, the establishment of the four mathematical identities which correspond to the condition of conservation or permanence of the material world.The Mathematical Theory of Relativity.By Prof. A.
