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.

Which geometries on a smooth manifold can serve as a spacetime structure? This question is comprehensively addressed from first principles, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold.

This textbook is a nonmathematical presentation of Einstein's theories of special and general relativity, including a brief treatment of cosmology. It is a set of lecture notes for the author's course Relativity for Poets at Fullerton College.

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.

A condensed unified presentation intended for one who has already digested the mechanics of tensor theory and physical basis of relativity. Einstein's little book serves as an excellent tying-together of loose ends and as a survey of the subject.
