The reader is taken through many fundamental discoveries, which are always described in a very appealing style. The book is profusely illustrated with photographs of the main players and respective apparatus, often complemented by pedagogical diagrams, and includes detailed references to original publications. It provides a stimulating way of learning about the basic concepts of modern physics and how they were brought to life. Once you start reading this book, it is difficult to stop.
