The Curvature of Spacetime

The internationally renowned physicist Harald Fritzsch deftly explains the meaning and far-flung 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 named Adrian Haller. In this entertaining and involving account of relativity, Newton serves as the skeptic and asks the questions a modern reader might ask. Einstein himself does the explaining, while Haller explains the new developments that have occurred since the general theory was proposed.
The Curvature of Spacetime is a time-travel dialogue set in 1996 between three men: Isaac Newton, Albert Einstein... and an imaginary modern expert, Adrian Haller... As an expository device, the dialogue form is quite successful. It lets Haller teach Einstein and Newton (and us) the current status, experimental and theoretical, of particle physics, drawing the reader into exchanges of view and conflicting ideas more readily than conventional exposition would allow. -- Francis Everitt, Nature
