John Naylor - Böcker

Why is the sky blue and why are sunsets red? When can I see a rainbow? Why is the moon sometimes visible in daylight? In Out of the Blue skywatcher John Naylor offers practical advice about where and when you can expect to see natural phenomena, what you will see and how to improve your chances of seeing it. He takes in both the night and the day sky, and deals only with what can be seen with the naked eye. Drawing on science, history, literature and mythology, and written in a popular style that assumes only basic scientific know-how, Out of the Blue is for everyone who enjoys being outdoors and who feels curious or puzzled about things optical and astronomical.

Originally published in 1987, at a time of high unemployment, this book provides a critical analysis of the role played by education in solving unemployment. It examines the practical, social and psychological effects of unemployment on adults and argues that formal institutional responses are inadequate within any long term perspective, and that it is rather community, informal and often unofficial initiatives that will provide learning experiences for unemployed people.

Since 1997 the Portable Antiquities Scheme has recorded almost 1.5 million objects found in England and Wales, the vast majority discovered by members of the public rather than professional archaeologists. Among these finds are more than 10,000 early medieval coins. Each one of these coins has its own story to tell, from its minting, use and loss through to its eventual recovery and recording.In this book, Dr John Naylor, the PAS’s National Finds Adviser for Early Medieval and Later Coinage, explores the Anglo-Saxon world through these coin finds, tracing the development of coinage from the end of Roman Britain to the Norman Conquest of 1066 and how they were used by early medieval people. As well as their use in trading, he shows how they can help us to understand how the Anglo-Saxons saw themselves through looking at coin design and iconography, and how they were used in diverse and interesting ways such as their inclusion in burials and hoards, and their re-use as items of jewellery.

The Watlington Hoard was discovered in southern Oxfordshire in 2015 by a metal-detectorist, and acquired by the Ashmolean Museum, Oxford in 2017. A nationally-important find of coinage and metalwork, and the first major Viking-Age hoard from the county, it dates from the late 870s, a fundamental and tumultuous period in Britain’s history. The contents of the hoard include a highly significant collection of over 200 silver pennies, mostly of Alfred the Great, king of Wessex, and Ceolwulf II, king of Mercia, transforming our understanding of the coinage in this period, and 23 silver and gold pieces of contemporary metalwork much of which was derived from Scandinavia.Presenting the complete publication of the objects and coins in the Watlington Hoard – including an important re-assessment of the coinage of the late 870s – the authors discuss its wider implications for our understanding of hoarding in late 9th-century southern Britain, interactions between the kingdoms of Wessex and Mercia, and the movements of the Viking Great Army after the Battle of Edington in 878. The book also relates another side to the hoard’s story, beginning with its discovery and excavation, charting its path through the conservation work and acquisition by the Ashmolean Museum to the public outreach projects which ran alongside the scholarly research into the hoard.

This book explains the nature of sound both as a physical phenomenon and as a sensation, how it travels through air and water, and how the hearing system evolved to convert these vibrations into sensations. Drawing on physics, biology, neuroscience, philosophy, literature, history, anecdote, and personal experience, "Now Hear This" is a wide-ranging exploration of the nature of sound and hearing that opens up a fascinating world of sounds from the mundane to the unusual and seeks above all to persuade the reader of the wisdom of John Cage’s advice that “Wherever we are what we hear is mostly noise. When we ignore it, it disturbs us. When we listen to it, we find it fascinating.”

Rainbows have been a source of fascination since time immemorial. They have been the subject of myth and superstition, an inspiration to poets, a challenge to painters, the object of intense scientific interest and a touchstone for ideas about the nature of light and colour. Above all, the rainbow has been the embodiment of wonder from the earliest times to the present day.Beginning with the circumstances in which you are likely to see a rainbow and descriptions of its salient features, this book recounts and explains the myths and superstitions about rainbows, and describes how poets, painters and, above all, leading scientists in every age have sought to discover and understand the rainbow’s secrets.Readers with a love of nature and art and an interest in the history of science will enjoy this attractive and informative book.
