This accessible reference presents the evolution of concepts of time and methods of time keeping, for historians, scientists, engineers, and educators. The second edition has been updated throughout to describe twentieth- and twenty-first-century advances, progress in devices, time and cosmology, the redefinition of SI units, and the future of UTC.
In the twenty-first century, we take the means to measure time for granted, without contemplating the sophisticated concepts on which our time scales are based. This volume presents the evolution of concepts of time and methods of time keeping up to the present day. It outlines the progression of time based on sundials, water clocks, and the Earth's rotation, to time measurement using pendulum clocks, quartz crystal clocks, and atomic frequency standards. Time scales created as a result of these improvements in technology and the development of general and special relativity are explained. This second edition has been updated throughout to describe twentieth- and twenty-first-century advances and discusses the redefinition of SI units and the future of UTC. A new chapter on time and cosmology has been added. This broad-ranging reference benefits a diverse readership, including historians, scientists, engineers, educators, and it is accessible to general readers.
Children do not always have the capacity or need to express themselves through words. They often succeed in saying more about their feelings and experiences by communicating non-verbally through play and other expressive, creative activities. The basic premise of Speaking about the Unspeakable is that life's most pivotal experiences, both good and bad, can be truly expressed via the language of the imagination. Through creativity and play, children are free to articulate their emotions indirectly. The contributors, all experienced child therapists, describe a wide variety of non-verbal therapeutic techniques, including clay, sand, movement and nature therapy, illustrating their descriptions with moving case studies from their professional experience. Accessible and engaging, this book will inspire child psychologists and therapists, art therapists and anyone with an interest in therapeutic work with children.
Why do we find polar bears only in the Arctic and penguins only in the Antarctic? Why do oceanic islands often have many types of birds but no large native mammals? As Charles Darwin and Alfred Russel Wallace travelled across distant lands studying the wildlife they both noticed that the distribution of plants and animals formed striking patterns - patterns that held strong clues to the past of the planet. The study of the spatial distribution of living things is known as biogeography. It is a field that could be said to have begun with Darwin and Wallace. In this lively book, Denis McCarthy tells the story of biogeography, from the 19th century to its growth into a major field of interdisci...
IAU Symposium No. 82, "Time and the Earth's Rotation", met to discuss modern research in the field of the rotation of the Earth with particu lar emphasis on the role of new observational techniques in this work. The use of these techniques has prompted a new look at the definitions of the traditional reference systems and the concepts of the rotation of the Earth around its center of mass. Specific topics discussed were time, polar motion, reference systems, conventional radio interferometry, very'long baseline interferometry (VLBI), Doppler satellite methods, satellite laser ranging, lunar laser ranging, and geophysical research concerning the Earth's rotation. Improvement in the accuracy o...
Dennis McCarthy's work with distressed or traumatized children begins with an exercise that is simple but effective: he invites the child to communicate with him in their own way, through the non-verbal language of play. This book is useful for play therapists and other professionals working therapeutically with young children and their families.

Cormac McCarthy both embodies and redefines the notion of the artist as outsider. His fiction draws on recognizable American themes and employs dense philosophical and theological subtexts, challenging readers by depicting the familiar as inscrutably foreign. The essays in this Companion offer a sophisticated yet concise introduction to McCarthy's difficult and provocative work. The contributors, an international team of McCarthy scholars, analyze some of the most well-known and commonly taught novels - Outer Dark, Blood Meridian, All the Pretty Horses and The Road - while providing detailed treatments of McCarthy's work in cinema, including the many adaptations of his novels to film. Designed for scholars, teachers and general readers, and complete with a chronology and bibliography for further reading, this Companion is an essential reference for anyone interested in gaining a deeper understanding of one of America's most celebrated living novelists.
The true story of a self-taught sleuth's quest to prove his eye-opening theory about the source of the world's most famous plays, taking readers inside the vibrant era of Elizabethan England as well as the contemporary scene of Shakespeare scholars and obsessives. What if Shakespeare wrote Shakespeare . . . but someone else wrote him first? Acclaimed author of The Map Thief, Michael Blanding presents the twinning narratives of renegade scholar Dennis McCarthy and Elizabethan courtier Sir Thomas North. Unlike those who believe someone else secretly wrote Shakespeare, McCarthy argues that Shakespeare wrote the plays, but he adapted them from source plays written by North decades before. In Sha...
