"Clear and coherent One of the most exciting aspects of the book is the author's account of how the consequences and implications of the breakthroughs in quantum mechanics challenged the mechanistic, deterministic philosophy fostered by classical science." The Science Teacher
Written by a respected Harvard physicist who did his doctoral work in Munich among many of the founding fathers of quantum mechanics, this introductory account of the evolution of quantum physics also explores the subject's philosophical implications. Beginning with brief background sketches, the author offers...

Multiplicity diagrams can be viewed as schemes for describing the phenomenon of "symmetry breaking" in quantum physics. The subject of this book is the multiplicity diagrams associated with the classical groups U(n), O(n), etc. It presents such topics as asymptotic distributions of multiplicities, hierarchical patterns in multiplicity diagrams, lacunae, and the multiplicity diagrams of the rank 2 and rank 3 groups. The authors take a novel approach, using the techniques of symplectic geometry. The book develops in detail some themes which were touched on in the highly successful Symplectic...
