Which geometries on a smooth manifold (apart from Lorentzian metrics) can serve as a spacetime structure? This question is comprehensively addressed from first principles in eight lectures, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold that can carry predictive matter equations, are time-orientable, and allow to distinguish positive from negative particle energies.

In the framework of the special theory of relativity, the relativistic theory of gravitation is constructed. The energy-momentum tensor density of all the matter fields (including gravitational one) is treated as a source of the gravitational field.

The first six lectures are devoted to Special Relativity, and the remaining ones to Einstein's General Relativity and Gravitation Theory and to relativistic Electromagnetism. Due attention is given to the critically conceptual side of the subject.

We introduce a relativistic splitting structure as a means to map equations of electromagnetism from curved four-dimensional space-time to 3-dimensional observer's space. We focus on mathematical structures that are motivated by the physical theory.

There is a constant demand for information about this much-debated topic of relativity. In order to make a popular explanation of this far-reaching theory available, the present book is published. (first published in 1920)
