‘[A] joyously readable book— it riffs along like breeze in the hedgerow.’ John Lewis-Stempel in Country Life ‘Hart’s passion for the potential that resides here is intoxicating. Occasionally an environmental solution comes along that is so breathtakingly simple you can’t believe that not everyone is already doing it.’ Sunday Times ‘[Hart] has written an eye-opening and inspiring book which will leave you with a deep appreciation of these wonderful habitats’ Daily Mail In this joyous journey around the wild edges of Britain, Christopher Hart takes us through the life, ecology and history of the humble British hedge, showing us how this much-loved (but somewhat overlooked) feature is inextricably woven into our language, history and culture. Hedges – or hedgerows – have long been an integral part of the British landscape; a bastion of privacy for our gardens, a protective presence on winding country lanes and a vital hiding place for birds and beasts on farmland. This man-made marvel is finally getting its time in the sun. Recognised as an environmental hero and a powerful climate ally, hedgerow is now considered the greatest edge habitat on earth, offering thorny scrub, mature woodland, grassland and even wetland. It plays a critical role in carbon sequestration and provides essential protection against the elements. Hedgelands highlights the hawthorn and hazel of ancient hedges; the abundance of wildlife, from the elusive dunnock to the striking nightingale, the industrious hedgehog to the little harvest mouse; and the free pickings that the hedgerow offers, making it an essential – and delicious – element of any countryside ramble. Hedgelands will tell you everything you never thought you needed to know about this wild, diverse and rich habitat – and you might even look at your humble hedge in a whole new way. ‘Hedgelands combines history, celebration, lament and warning. Christopher Hart is a companionable writer, and makes a powerful case that, at a time of ecological hazard, well-nurtured hedges can play an astonishing role in buttressing the future.’ The Spectator ‘A wonderful history of the threads that stitch the British countryside together.’ Jake Fiennes, author of Land Healer ‘A passionate celebration and exploration of our wonderful hedgerows. You’ll be swept along by Hart’s intoxicating enthusiasm.’ Dave Goulson, author of Silent Earth
Experimental advances in helium atom scattering spectroscopy over the last forty years have allowed the measurement of surface phonon dispersion curves of more than 200 different crystal surfaces and overlayers of insulators, semiconductors and metals. The first part of the book presents, at a tutorial level, the fundamental concepts and methods in surface lattice dynamics, and the theory of atom-surface interaction and inelastic scattering in their various approximations, up to the recent electron-phonon theory of helium atom scattering from conducting surfaces. The second part of the book, after introducing the experimentalist to He-atom spectrometers and the rich phenomenology of helium atom scattering from corrugated surfaces, illustrates the most significant experimental results on the surface phonon dispersion curves of various classes of insulators, semiconductors, metals, layered crystals, topological insulators, complex surfaces, adsorbates, ultra-thin films and clusters. The great potential of helium atom scattering for the study of atomic scale diffusion, THz surface collective excitations, including acoustic surface plasmons, and the future prospects of helium atom scattering are presented in the concluding chapters. The book will be valuable reading for all researchers and graduate students interested in dynamical processes at surfaces.
