Authored by two highly respected experts in this specialist area, The Fundamentals of Radiation Thermometers is an essential resource for anyone intending to measure the temperature of an object using the radiated energy from that object. This readable, user-friendly book gives important background knowledge for anyone working in the field of non-contact thermometry. The book begins with an accessible account of how temperature scales are set up and defined, and explores the historic development of temperature scales and Planck's radiation law. Through explaining the reliability of both emissivity values and extrapolation to different wavelengths and temperatures, the book provides a foundation for understanding when a valid measurement with realistic uncertainties has been made, or if an inappropriate emissivity value has been used with consequent unknown errors. The book also presents the hardware of radiation thermometers, allowing the reader to specify an appropriate design for a particular measurement problem. It explores multi-wavelength radiation thermometry and its associated pitfalls, and a final chapter suggests strategies to minimise the uncertainties from unreliable emissivity data.

The influence of human economies and cultures on ecosystems is particularly striking in the new worlds into which Europeans have expanded over the past five hundred years. Using a comparative and multidisciplinary approach, Beinart and Coates examine this neglected aspect of the history of settler incursion and dominance in two frontier nations, the USA and South Africa. They also seek to explain change in indigenous ideas and practices towards the environment, and discuss the rise of popular environmentalism up to the present day.

Squirrel Nation is a history of Britain’s two species of squirrel over the past two hundred years. The red squirrel, although rare, is among the most cherished of native species. Grey squirrels, by contrast, are one of the most frequently seen wild creatures in our gardens, parks, towns and countryside, and many Britons consider it to be a foreign interloper, introduced from North America in the late nineteenth century. By examining this animal’s colonization of Britain, Peter Coates also explores timely issues of belonging, nationalism, citizenship and the defence of borders within Britain today. Ultimately, though people are swift to draw distinctions between British squirrels and squirrels in Britain, Squirrel Nation shows that Britain’s two squirrel species have much more in common than at first appears.

In these global times it is a curious and pertinent fact that the life and writings of Muhyiddin Ibn 'Arabi, which since the 12th century have incalculably influenced the metaphysical structure of much Oriental thought and practice, still remain relatively unknown and undiscussed in the Western theoretical architecture of the twenty-first century. His remarks on causality, time, contingency, necessity, epistemology, ontology, ethics and aesthetics alone would entice even the most wary of modernity's intellectual authorities. This book deals with the findings of just some of these authorities modern philosophy, social science and psychology in an open discourse between the ancient and the modern, the traditional and the scientific, the industrial and the personal. It is an invitation to reconsider some of the central and defining ideas of modernity in the light of Ibn 'Arabi's writings on the Unity of Existence. The book will be of interest to academics and students in psychology, sociology and philosophy, and to readers with an academic and/or personal interest in Ibn 'Arabi.

Preparation for warfare materially reshapes rural landscapes and environments; this is a comparative history and geography of militarized landscapes. The black smoke billowing from burning oil wells during the Gulf War of 1990-91 directed media and public attention towards war's devastating environmental impact. Yet even before the first bomb is dropped, preparation for warfare materially and imaginatively reshapes rural landscapes and environments. This volume is the first to explore the comparative histories and geographies of militarized landscapes. Moving beyond the narrow definition of militarized landscapes as theatres of war, it treats them as simultaneously material and cultural sites that have been partially or fully mobilized to achieve military aims. Ranging from the Korean DMZ to nuclear testing sites in the American West, and from Gettysburg to Salisbury Plain, "Militarized Landscapes" focuses on these often secretive, hidden, dangerous and invariably controversial sites that occupy huge swathes of national territories.

Sometimes by accident and sometimes on purpose, humans have transported plants and animals to new habitats around the world. Arriving in ever-increasing numbers to American soil, recent invaders have competed with, preyed on, hybridized with, and carried diseases to native species, transforming our ecosystems and creating anxiety among environmentalists and the general public. But is American anxiety over this crisis of ecological identity a recent phenomenon? Charting shifting attitudes to alien species since the 1850s, Peter Coates brings to light the rich cultural and historical aspects of this story by situating the history of immigrant flora and fauna within the wider context of human immigration. Through an illuminating series of particular invasions, including the English sparrow and the eucalyptus tree, what he finds is that we have always perceived plants and animals in relation to ourselves and the polities to which we belong. Setting the saga of human relations with the environment in the broad context of scientific, social, and cultural history, this thought-provoking book demonstrates how profoundly notions of nationality and debates over race and immigration have shaped American understandings of the natural world.
