A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.

This study analyzes chamber music from Mozart's time within its highly social salon-performance context.

Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

"The impact of technology on society is clear and unmistakeable. The influence of society on technology is more subtle. The 13 essays in this book have been written by a diverse group of scholars united by a common interest in creating a new field - the sociology of technology. They draw on a wide array of case studies - from cooking stoves to missile systems, from 15th-century Portugal to today's Al labs - to outline an original research program based on a synthesis of ideas from the social studies of science and the history of technology. Together they affirm the need for a study of technology that gives equal weight to technical, social, economic, and political questions"--Back cover.

The universality of musical tones has long fascinated philosophers, scientists, musicians, and ordinary listeners. Why do human beings worldwide find some tone combinations consonant and others dissonant? Why do we make music using only a small number of scales out of the billions that are possible? Why do differently organized scales elicit different emotions? Why are there so few notes in scales? In Music as Biology, Dale Purves argues that biology offers answers to these and other questions on which conventional music theory is silent. When people and animals vocalize, they generate tonal sounds—periodic pressure changes at the ear which, when combined, can be heard as melodies and harmonies. Human beings have evolved a sense of tonality, Purves explains, because of the behavioral advantages that arise from recognizing and attending to human voices. The result is subjective responses to tone combinations that are best understood in terms of their contribution to biological success over evolutionary and individual history. Purves summarizes evidence that the intervals defining Western and other scales are those with the greatest collective similarity to the human voice; that major and minor scales are heard as happy or sad because they mimic the subdued and excited speech of these emotional states; and that the character of a culture’s speech influences the tonal palette of its traditional music. Rethinking music theory in biological terms offers a new approach to centuries-long debates about the organization and impact of music.

From the author of The Changing Mind and The Organized Mind comes a New York Times bestseller that unravels the mystery of our perennial love affair with music ***** 'What do the music of Bach, Depeche Mode and John Cage fundamentally have in common?' Music is an obsession at the heart of human nature, even more fundamental to our species than language. From Mozart to the Beatles, neuroscientist, psychologist and internationally-bestselling author Daniel Levitin reveals the role of music in human evolution, shows how our musical preferences begin to form even before we are born and explains why music can offer such an emotional experience. In This Is Your Brain On Music Levitin offers nothing less than a new way to understand music, and what it can teach us about ourselves. ***** 'Music seems to have an almost wilful, evasive quality, defying simple explanation, so that the more we find out, the more there is to know . . . Daniel Levitin's book is an eloquent and poetic exploration of this paradox' Sting 'You'll never hear music in the same way again' Classic FM magazine 'Music, Levitin argues, is not a decadent modern diversion but something of fundamental importance to the history of human development' Literary Review
