Amongst the numerous texts on the subject, the authors have succeeded in creating a novel approach to the understanding of quantum physics based on four novel features: - deliberate use of qualitative methods and heuristic arguments rather than formal calculations; - permanent reference to contemporary experimental results in many modern fields of physics (nuclear and high energy, neutronics, solid state, lasers, etc.); - careful discussion of conceptual difficulties and terminological problems from the present standpoint; - presentation of modern theoretical viewpoints (such as symmetry principles). An impressive selection of original problems supplement this up-to-date and comprehensive introduction to quantum physics. Quantics - Rudiments will be appreciated by a wide audience, from educated layman to professional scientist.
