This book is intended to engage the students in the elegance of electrodynamics and special relativity, whilst giving them the tools to begin graduate study. Here, from the basis of experiment, the authors first derive the Maxwell equations and special relativity. Introducing the mathematical framework of generalized tensors, the laws of mechanics, Lorentz force and the Maxwell equations are then cast in manifestly covariant form. This provides the basis for graduate study in field theory, high energy astrophysics, general relativity and quantum electrodynamics. As the title suggests, this book is "electrodynamics lite". The journey through electrodynamics is kept as brief as possible, with minimal diversion into details, so that the elegance of the theory can be appreciated in a holistic way. It is written in an informal style and has few prerequisites; the derivation of the Maxwell equations and their consequences is dealt with in the first chapter. Chapter 2 is devoted to conservation equations in tensor formulation; here, Cartesian tensors are introduced. Special relativity and its consequences for electrodynamics are introduced in Chapter 3 and cast in four-vector form, and here, the authors introduce generalized tensors. Finally, in Chapter 4, Lorentz frame invariant electrodynamics is developed. Supplementary material and examples are provided by the two sets of problems. The first is revision of undergraduate electromagnetism, to expand on the material in the first chapter. The second is more advanced corresponding to the remaining chapters, and its purpose is twofold: to expand on points that are important, but not essential, to derivation of manifestly covariant electrodynamics, and to provide examples of manipulation of cartesian and generalized tensors. As these problems introduce material not covered in the text, they are accompanied by full worked solutions. The philosophy here is to facilitate learning by problem solving, as well as by studying the text. Extensive appendices for vector relations, unit conversion and so forth are given with graduate study in mind.

This is the first of five ambitious volumes theorizing the structure of governance above and below the central state. This book is written for those interested in the character, causes, and consequences of governance within the state and for social scientists who take measurement seriously. The book sets out a measure of regional authority for 81 countries in North America, Europe, Latin America, Asia, and the Pacific from 1950 to 2010. Subnational authority is exercised by individual regions, and this measure is the first that takes individual regions as the unit of analysis. On the premise that transparency is a fundamental virtue in measurement, the authors chart a new path in laying out their theoretical, conceptual, and scoring decisions before the reader. The book also provides summaries of regional governance in 81 countries for scholars and students alike. Transformations in Governance is a major new academic book series from Oxford University Press. It is designed to accommodate the impressive growth of research in comparative politics, international relations, public policy, federalism, environmental and urban studies concerned with the dispersion of authority from central states up to supranational institutions, down to subnational governments, and side-ways to public-private networks. It brings together work that significantly advances our understanding of the organization, causes, and consequences of multilevel and complex governance. The series is selective, containing annually a small number of books of exceptionally high quality by leading and emerging scholars. The series targets mainly single-authored or co-authored work, but it is pluralistic in terms of disciplinary specialization, research design, method, and geographical scope. Case studies as well as comparative studies, historical as well as contemporary studies, and studies with a national, regional, or international focus are all central to its aims. Authors use qualitative, quantitative, formal modeling, or mixed methods. A trade mark of the books is that they combine scholarly rigour with readable prose and an attractive production style. The series is edited by Liesbet Hooghe and Gary Marks of the University of North Carolina, Chapel Hill, and the VU Amsterdam, and Walter Mattli of the University of Oxford.

The 26-metre-long Diplodocus skeleton that dominates the Central Hall of the Natural History Museum in London is one of the world's most famous dinosaur models. Known affectionately as 'Dippy', it has fascinated and enthralled visitors since it was first revealed to an astonished public in 1905. Dippy's tale begins some 150 million years ago in the late part of the Jurassic period - the time from which the original fossil dates. Dippy is an exact plaster replica of the fossilized bones found in the badlands of Wyoming, USA. The story of how Dippy came to the Museum is one that involves danger and adventure in the harsh environment of the American Wild West, the generosity of an eccentric millionaire and the involvement of the British royal family. The book combines an engaging narrative with details of dinosaur discoveries and the latest research on Diplodocus anatomy and behaviour. It also reveals the emergence of Dippy's importance to scientists, as studies on Diplodocus kick-started a renaissance in the understanding of the biology of the group it belongs to, the sauropods.Featuring delightful artworks and photographs throughout, this is both an engaging tale of discovery and a guide to one of the longest land animals ever to walk the Earth.
