Britannica Guide to Particle Physics 

While the atom is universally acknowledged as the basis for most branches of physics, the study of its constituent particles has illuminated significant new areas of research. The behavior of subatomic particles provides crucial information on the structure and nature of atomic nuclei, which in turn reveal much about energy, matter, and often the origins of the universe. Complete with color diagrams and photographs, this volume elucidates the intricacies of this rapidly developing and always compelling field.
