Acclaimed by Tolstoy as "one of the greatest English writers and one of the greatest writers of our age," John Ruskin continues to enjoy widespread popularity among modern readers. In addition to his roles as art critic and patron, watercolorist, and draughtsman, Ruskin ranks among the nineteenth century's most prominent social thinkers and philanthropists. His art criticism redefined the genre and his ideas related to politics and society, revolutionary in their day, anticipated current trends in environmentalism, sustainability, and craft.Throughout his long and prolific careers as educator and author, Ruskin focused on the associations among nature, art, and society. This anthology features well-chosen examples of that synthesis, drawing from some of his best-known books, including Modern Painters and The Stones of Venice. Students and other readers will find this volume the perfect introduction to the Victorian sage's voluminous works.

A foundational text of Western education, this 1762 treatise served as a model for a new approach to teaching during the French Revolution. Emile recounts a boy's education, and Rousseau considered it the most important of his writings. With its theories on the retention of innate human goodness and the avoidance of corruption from bourgeois society, the book offers prime examples of the author's philosophy. Rousseau's five-part approach devotes the first three sections to Emile's early education, including the child's interactions with the larger world and the selection of a trade. The fourth part explores the cultivation of sentiment, with particular focus on natural religion. The book concludes with a profile of Emile's prospective bride, Sophie, that emphasizes the role of mothers in educating their children but encourages women to be submissive to their husbandsa view that excited controversy even among Rousseau's contemporaries and helped inspire Mary Wollstonecraft's A Vindication of the Rights of Woman.

This classic monograph on representation theory and the symmetric group is suitable for advanced undergraduates and graduate students of mathematics. The Bulletin of the American Mathematical Society hailed Daniel Edwin Rutherford's treatment as "a long overdue account of Young's representation theory of the symmetric group," noting that "many of Young's complicated proofs have been simplified through a free use of mathematical induction."Starting with an elementary overview of the theory of the symmetric group, the book proceeds to an examination of Young's formula, followed by an introduction to the fundamental notion of a standard diagram. Subsequent chapters present the passage to orthogonal and natural representations. No prior knowledge of the general theory of group characters is assumed, and the author deduces the necessary theory for the symmetric group. The final chapter illustrates the substitutional aspect of the theory, and a helpful appendix and bibliography conclude the text.

One of the most beloved pieces in the modern violin repertoire, the Concerto in B Minor is among Edward Elgar's longest orchestral compositions and one of the last of his works to achieve and retain popular success. This practice and performance edition contains a piano reduction and a separate violin part.Famed violinist Fritz Kreisler pronounced Elgar the greatest living composer, placing him "on an equal footing with my idols, Beethoven and Brahms. He is of the same aristocratic family. His invention, his orchestration, his harmony, his grandeurit is wonderful. I wish Elgar would write something for the violin." A commission from the Royal Philharmonic Society helped fulfill Kreisler's wish, and the violinist performed the Concerto in B Minor at its 1910 debut, with Elgar conducting the London Symphony Orchestra.

An Introduction to Phase-Integral Methods

# data[].attributes.description
The phase-integral method in mathematics, also known as the Wentzel-Kramers-Brillouin (WKB) method, is the focus of this introductory treatment. Author John Heading successfully steers a course between simplistic and rigorous approaches to provide a concise overview for advanced undergraduates and graduate students in mathematics and physics. Since the number of applications is vast, the text considers only a brief selection of topics and emphasizes the method itself rather than detailed applications. The process, once derived, is shown to be one of essential simplicity that involves merely the application of certain well-defined rules. Starting with a historical survey of the problem and its solutions, subjects include the Stokes phenomenon, one and two transition points, and applications to physical problems. An appendix and bibliography conclude the text.
