The Physics of Quantum Mechanics aims to give students a good understanding of how quantum mechanics describes the material world. It shows that the theory follows naturally from the use of probability amplitudes to derive probabilities. It stresses that stationary states are unphysical mathematical abstractions that enable us to solve the theory's governing equation, the time-dependent Schroedinger equation. Every opportunity is taken to illustrate the emergence of the familiar classical, dynamical world through the quantum interference of stationary states. The text stresses the continuity between the quantum world and the classical world, which is merely an approximation to the quantum world. The connections between observables, operators and transformations are clearly explained and the standard commutation rules derived from the properties of spacetime. A chapter is devoted to entanglement, quantum computation, density operators and their role in thermodynamics, and the measurement problem. Scattering phenomena, including the origin of radioactivity, are handled early on in the accessible context of one dimension, and at the end of the book with some rigour in three dimensions. Hydrogen and helium are discussed in some detail and it is shown that quantum mechanics enables us to understand the structure of the periodic table without engaging with the complexities of many-electron atoms. Dirac notation is used from the outset and students are trained to move easily from one representation to another, choosing whichever representation is best suited to a particular problem. The mathematical prerequisites are no more than simple vector algebra, Taylor series expansion and the use of integrating factors to solve linear first order differential equations. Rigorous algebraic methods are preferred to the solution of partial differential equations.

Racial and ethnic categories have appeared in recent scientific work in novel ways and in relation to a variety of disciplines: medicine, forensics, population genetics and also developments in popular genealogy. Once again, biology is foregrounded in the discussion of human identity. Of particular importance is the preoccupation with origins and personal discovery and the increasing use of racial and ethnic categories in social policy. This new genetic knowledge, expressed in technology and practice, has the potential to disrupt how race and ethnicity are debated, managed and lived. As such, this volume investigates the ways in which existing social categories are both maintained and transformed at the intersection of the natural (sciences) and the cultural (politics). The contributors include medical researchers, anthropologists, historians of science and sociologists of race relations; together, they explore the new and challenging landscape where biology becomes the stuff of identity.

Essays on important topics in early music. Christopher Page is one of the most influential and distinguished scholars and performers of medieval music. His first book, Voices and Instruments of the Middle Ages (1987), marked the beginning of what might be called the"Page turn" in the study and performance of medieval music. His many subsequent publications, radio broadcasting (notably the series Spirit of the Age) and performances and recordings with his ensemble Gothic Voices changed the perception of and thinking about music from before about 1400 and forged new ways of communicating its essence to scholars as well as its subtle beauty to wider audiences. The essays presented here in his honour reflectthe broad range of subject-matter, from the earliest polyphony to the conductus and motet of the thirteenth and fourteenth centuries, the troubadour and trouvère repertories, song and dance, church music, medieval music theory, improvisation techniques, historiography of medieval music, musical iconography, instrumental music, performance practice and performing, that has characterised Page's major contribution to our knowledge of music of the Middle Ages.

How does new information technology become part of the fabric of organisational life? Drawing on insights from social studies of technology, gender studies and the sociology of consumption, Valuing Technology opens up new directions in the analysis of sociotechnical change within organisations. Based on a major research project focused upon the introduction of management of information systems in health, higher education and retailing, I explores the active role of end-users in innovation.
This book argues that it is through the, often difficult, engagement between users and technology that new computer systems come to gain value within organisations. Key themes developed through analysis of case studies include:
*the valuing of technology via the on-going construction of needs, uses and utilities
*occupational identities, organisational inequalities and technological change
*the gendering of technological and organisational change
*interpretive flexibility and the 'stabilisation' of technological systems and their incorporation into the lives of people in organisations.
A stimulating blend of the theoretical and substantive, this book demands a radical redefinition of 'technology acquisition'. It's highly original approach makes Valuing Technology essential reading for students, lecturers and researchers within the fields of organisation studies and the sociology of technology.

What purpose does the news media serve in contemporary North American society? In this collection of essays, experts from both the United States and Canada investigate this question, exploring the effects of media concentration in democratic systems. Specifically, the scholars collected here consider, from a range of vantage points, how corporate and technological convergence in the news industry in the United States and Canada impacts journalism's expressed role as a medium of democratic communication. More generally, and by necessity, Converging Media, Diverging Politics speaks to larger questions about the role that the production and circulation of news and information does, can, and should serve. The editors have gathered an impressive array of critical essays, featuring interesting and well-documented case studies that will prove useful to both students and researchers of communications and media studies.

Created by the most respected American publisher of dictionaries and supervised by the editor Philip Gove, Webster's Third broke with tradition, adding thousands of new words and eliminating artificial notions of correctness, basing proper usage on how language was actually spoken. The dictionary's revolutionary style sparked what David Foster Wallace called the Fort Sumter of the Usage Wars. Editors and scholars howled for Gove's blood, calling him an enemy of clear thinking, a great relativist who was trying to sweep the English language into chaos. Critics bayed at the dictionary's permissive handling of ain't. Literary intellectuals such as Dwight Macdonald believed the dictionary's scientific approach to language and its abandonment of the old standard of usage represented nothing less than the unraveling of civilization. Entertaining and erudite, and a New York Times Book Review Editor's Choice, The Story of Ain't describes a great societal metamorphosis, tracing the fallout of the world wars, the rise of an educated middle class, and the emergence of America as the undisputed leader of the free world, and illuminating how those forces shaped our language. Never before or since has a dictionary so embodied the cultural transformation of the United States.

Few decades have caused more controversy than the 1960s, a time of explosive change in which tradition and authority gave way to freedom - a sweeping transformation crystalized in the 1961 publication of "Webster's Third New International Dictionary". Created by the most respected American publisher of dictionaries and supervised by editor Philip Gove, Webster's Third broke with convention, adding thousands of new words and eliminating artificial notions of correctness, basing proper usage on how language was actually spoken. The dictionary's revolutionary style sparked debate in universities, libraries, newspapers, and living rooms nationwide. Critics instantly took umbrage at the dictionary's handling of ain't, among other blasphemies. Literary intellectuals like Dwight Macdonald believed the dictionary's scientific approach to language and its abandonment of the old standard of usage represented the end of civilization. In this intriguing history, David Skinner tells the story of the people who made the dictionary, those who denounced it, and the forces that shaped it. He traces the shift in the American lexicon in the decades leading up to 1961, identifying the changes that affected our language from the Great Depression through World War II to the 1950s. As America became the undisputed leader of the free world, its citizens were becoming more educated. What came to be known as middlebrow culture was born, and alongside it a cadre of cultural critics, including Macdonald who condemned its permissiveness and divergence from standards. Entertaining and erudite, "The Story of Ain't" describes a great social metamorphosis in America and illuminates the intriguing yet little known early episode in the culture war that continues to divide the nation.
