This introductory textbook - now in its third edition - gives a uniform presentation of nuclear and particle physics. The first part is devoted to disentangling the substructure of matter. The part shows that experiments designed to uncover the substructures of nuclei and nucleons have a similar conceptual basis, and lead to the present picture of all matter being built out of a small number of elementary building blocks and a small number of fundamental interactions. The second part shows how the elementary particles may be combined to build hadrons and nuclei. The fundamental interactions responsible for the forces in all systems become less and less evident in increasingly complex systems. In the third edition a new section on neutrino oscillations and one on nuclear matter at high temperatures bridges the fields of modern astrophysics and cosmology. This concise text is well suited for advanced and undergraduate courses.|| Some praise for the previous ||" . . . An excellent introduction to nuclear and particle physics . . . A very clear presentation . . . I thus recommend this book as a very good phenomenological approach to the physics of particles and nuclei . . . "|- Physicalia
