"The Daughter of Anderson Crow" by George Barr McCutcheon When baby Rosalie is left on Anderson Crow's doorstep on a cold February night in 1883, he and his wife have no objections against raising her, especially when they find a note promising them a $1,000 payment for every year that the girl is in their care. However, that doesn't stop their curiosity and the curiosity of everyone in the neighborhood as to the parents of this mysterious little girl. Though the mystery drives the book, its characters are written so realistically and charmingly, that they keep the story grounded and full of heart.

Symmetry: An Introduction to Group Theory and its Application is an eight-chapter text that covers the fundamental bases, the development of the theoretical and experimental aspects of the group theory. Chapter 1 deals with the elementary concepts and definitions, while Chapter 2 provides the necessary theory of vector spaces. Chapters 3 and 4 are devoted to an opportunity of actually working with groups and representations until the ideas already introduced are fully assimilated. Chapter 5 looks into the more formal theory of irreducible representations, while Chapter 6 is concerned largely with quadratic forms, illustrated by applications to crystal properties and to molecular vibrations. Chapter 7 surveys the symmetry properties of functions, with special emphasis on the eigenvalue equation in quantum mechanics. Chapter 8 covers more advanced applications, including the detailed analysis of tensor properties and tensor operators. This book is of great value to mathematicians, and math teachers and students.

High-level text applies group theory to physics problems, develops methods for solving molecular vibration problems and for determining the form of crystal tensors, develops translational properties of crystals, more. 1974 edition.
