Relativity: the Special and General Theory

The book is composed of three parts. Part one presents the Special Theory of Relativity and the intimate connection of space and time (spacetime, or "ST"). Part two highlights the General Theory of Relativity, in which Einstein argues that space and time are not absolute and are modified by gravitational forces. In part three, Einstein applies these theories to a consideration of the universe as a whole, with specific discussion about Newton's Law and a sketch of the structure of space according to the General Theory of Relativity. The book frequently refers to an analogy involving a man on a train and a man on and embankment, to which Einstein applies his theories to present varying outcomes. These analogies greatly enhance the layperson's understanding.
