“Can only a genius understand Einstein? No…” claims author Markus Pössel on the back cover of his new book, which is aimed at the reader who is interested in modern science. Among the many books to mark the 100th anniversary of Einstein’s annus mirabilis, this one appeals immediately because of its high-quality design and the many colourful photos and illustrations. But can it deliver on its promise?
In the first part we are led to the basic concepts of special and general relativity, following a more phenomenological approach. With the help of facts, many pictures and stories relating to everyday life, Pössel manages to give us a flavour of this new world of extremes. Numerical examples substitute for mathematical equations and give a notion of reality. Minkowski diagrams are introduced and used wherever possible. In the context of general relativity, emphasis is put on the correct development of the geometrical principles, which is done with great care.
The second part covers the applications of relativity: our solar system, gravitational waves, stars, black holes and cosmology. The comparatively short third part is a surprisingly detailed discussion of gravitational-wave detection, which puts the reader at the forefront of this exciting field of research.
The chosen approach to relativity is similar to that of university textbooks, where all mathematical equations are substituted by pictures and numerical examples. This disguises the essential principles and occasionally makes it a cumbersome read. It is also questionable whether the sometimes awkward embellishments to the explanations serve the purpose of clarity. Nevertheless, Pössel takes the reader on an exciting journey through space-time.
“Can only a genius understand Einstein?” With this book in hand, average readers can understand him too, provided their curiosity is strong enough to help them find the necessary patience and stamina.
