Differential geometry is the study of curved spaces using the techniques of calculus. It is a mainstay of undergraduate mathematics education and a cornerstone of modern geometry. It is also the language used by Einstein to express general relativity, and so is an essential tool for astronomers and theoretical physicists. This introductory textbook originates from a popular course given to third year students at Durham University for over twenty years, first by the late L. M. Woodward and later by John Bolton (and others). It provides a thorough introduction by focusing on the beginnings of the subject as studied by Gauss: curves and surfaces in Euclidean space. While the main topics are the classics of differential geometry - the definition and geometric meaning of Gaussian curvature, the Theorema Egregium, geodesics, and the Gauss-Bonnet Theorem - the treatment is modern and student-friendly, taking direct routes to explain, prove and apply the main results. It includes many exercises to test students' understanding of the material, and ends with a supplementary chapter on minimal surfaces that could be used as an extension towards advanced courses or as a source of student projects.

This volume traces the complex reasons behind the disturbing discrepancy between the health and well-being of children in mainstream Australia and those in remote Indigenous communities. Invaluably informed by Boulton's close working knowledge of Aboriginal communities, the book addresses growth faltering as a crisis of Aboriginal parenting and a continued problem for the Australian nation. The high rate and root causes of ill-health amongst Aboriginal children are explored through a unique synthesis of historical, anthropological, biological and medical analyses. Through this fresh approach, which includes the insights of specialists from a range of disciplines, Aboriginal Children, History and Health provides a thoughtful and innovative framework for considering Indigenous health.

Popular conservative blogger Pamela Geller and New York Times bestselling author Robert Spencer sound a wake-up call for Americans to stop the Obama administration from limiting our hard-won freedoms, silencing our democratic voices, and harming America for generations to come--now available in paperback.
America is being tested in a way that she has never been tested before. Since taking the oath of office in January 2009, President Barack Obama has cheered our enemies and demoralized our allies. He is hard at work "remaking" America by destroying the free-market system and nationalizing major segments of our economy, demonizing dissent and restricting freedom of speech, turning against our longtime friends, and above all, subjecting us to the determinations of foreign authorities. In this timely and urgent battle cry, Pamela Geller, founder of the widely popular website AtlasShrugs.com, and bestselling author Robert Spencer team up to expose the Obama administration's destructive agenda--largely ignored by the mainstream media--and rally Americans to protect the sovereignty of a country that is under siege. Geller and Spencer critically examine the Obama administration's ominous and revealing moves against our basic freedoms, particularly as he seizes control of the three engines of the American economy: health care, energy, and education. "The Post-American Presidency" is a vital guide to helping conservatives prepare for the tough battles ahead.
