The curvature of spacetime. Newton, Einstein and gravitation

The physicist Harald Fritzsch explains the meaning and implications of the general theory of relativity and other mysteries of modern physics by presenting an imaginary conversation among Newton, Einstein and a fictitious contemporary particle physicist called Adrian Haller. In this account of relativity, Newton serves as the sceptic and asks the questions a modern reader might ask. Einstein himself does the explaining while Haller explains the new developments that have occured since the general theory was proposed.
