This translation from the German is a unique book. Bridging the gap between classical
and relativistic concepts, the author describes a variety of phenomena of modern physics
in storybook fashion. The goal is to give a broad segment of the public a
"hands-on" appreciation of ideas that are contrary to everyday common
sense--ideas that have seemed totally out of the reach of most nonscientists. Fritzsch
accomplishes his goal by introducing three characters: Sir Isaac Newton and Albert
Einstein return from the dead and meet Professor Adrian Haller, an American physicist from
the present. Newton asks questions about what has happened in physics since his death that
he--and presumably, the reader--cannot comprehend. Einstein also asks questions, and the
three characters have several entertaining discussions. Using these discourses, Fritzsch
guides the reader slowly through a variety of topics related to Einstein's work, from the
equivalence of mass and energy (E = mc^{2}) and the twin paradox to time
dilation/space contraction and elementary particles. The book contains several historical
black-and-white photographs, a few simple graphs, very few basic mathematical equations,
and a helpful glossary. The equations could be skipped by readers with a fear of algebra
without causing any disruption in continuity. This is a fascinating, educational book.
