The book offers an alternative to Einstein's special theory of relativity, with the main purpose of developing a form of relativity, which (in contrast to Einstein's relativity) can be combined with quantum mechanics and thus can open to a unified field theory. We refer to the alternative as many-minds relativity, requiring different observers to agree on different information to different precision, asking for high precision only on essential information.

This is a textbook on theories of special and general relativity. It is assumed that the reader has an understanding of mathematics through calculus and partial differential equations. The relevant tensor calculus is presented throughout as needed.

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.

A book for the inquisitive reader who wishes to understand the main ideas of special and general theory of relativity. Only a modest understanding of high school mathematics is required. A formal account of special relativity is given in an appendix.

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.
