This book consists of a series of lectures introducing what the author believes to be the theoretical minimum for the understanding of nuclear spin dynamics, the branch of physics underpinning magnetic resonance techniques such as NMR and MRI. Spin dynamics ultimately concern the study of the state and time evolution of systems made by a large collection of particles possessing spin, one of the most subtle and indeed fascinating concepts in relativistic quantum mechanics and whose understanding requires a mix of quantum mechanics, Hamiltonian dynamics and advanced mathematics. Written in the concise and direct style appropriate for university lectures, this book is addressed to both undergra...
Myths of Europe focuses on the identity of Europe, seeking to re-assess its cultural, literary and political traditions in the context of the 21st century. Over 20 authors – historians, political scientists, literary scholars, art and cultural historians – from five countries here enter into a debate. How far are the myths by which Europe has defined itself for centuries relevant to its role in global politics after 9/11? Can ‘Old Europe’ maintain its traditional identity now that the European Union includes countries previously supposed to be on its periphery? How has Europe handled relations with the non-European Other in the past and how is it reacting now to an influx of immigrants and asylum seekers? It becomes clear that founding myths such as Hamlet and St Nicholas have helped construct the European consciousness but also that these and other European myths have disturbing Eurocentric implications. Are these myths still viable today and, if so, to what extent and for what purpose? This volume sits on the interface between culture and politics and is important reading for all those interested in the transmission of myth and in both the past and the future of Europe.
Mediterranean islands exhibit many similarities in their biotic ecological, physical and environmental characteristics. There are also many differences in terms of their human colonization and current anthropogenic pressures. This book addresses in three sections these characteristics and examines the major environmental changes that the islands experienced during the Quaternary period. The first section provides details on natural and cultural factors which have shaped island landscapes. It describes the environmental and cultural changes of the Holocene and their effects on biota, as well as on the current human pressures that are now threats to the sustainability of the island communities...

David Childress, popular author and star of the History Channel’s show Ancient Aliens, brings us the incredible story of the Cham: Egyptian-Hindu-Buddhist seafarers who ruled a realm that was as big as the Pacific Ocean. The mysterious Cham, or Champa, peoples of Southeast Asia formed a megalith-building, seagoing empire that extended into Indonesia, Fiji, Tonga, Micronesia, and beyond—a transoceanic power that reached Mexico, the American Southwest and South America. The Champa maintained many ports in what is today Vietnam, Cambodia, and Indonesia (particularly on the islands of Sulawesi, Sumatra and Java), and their ships plied the Indian Ocean and the Pacific, bringing Chinese, Afric...
This book constitutes the thoroughly refereed post-proceedings of the ICM 2002 International Satellite Conference on Electronic Information and Communication in Mathematics, held in Beijing, China, in August 2002. The 18 revised and reviewed papers assess the state of the art of the production and dissemination of electronic information in mathematics. Among the topics addressed are models and standards for information and metainformation representation; data search, discovery, retrieval, and analysis; access to distributed and heterogeneous digital collections; intelligent user interfaces to digital libraries; information agents, and cooperative work on mathematical data; digital collection generation; business models; and data security and protection.
Cosmology, the mysteries of the pyramids, ancient nuclear weapons, Atlantis, and the role of our government through history all come together in this book.
This work provides insights into the physical and human geography of Sardinia, the second largest Mediterranean island, with its complex, varied, changing and often hidden features. The title, “Surrounded by Water”, recalls the identity of a land whose coastlines and surrounding seas have symbolically represented social, economic, political, cultural bridges or walls, meeting or colliding places, over its long and difficult history. Landscapes, seascapes and cityscapes are presented and analysed, together with other aspects, through a descriptive focus and original contributions provided by some local experts, in order to offer scholars and students across the globe a complex and multi-d...
David Hatcher Childress, popular Lost Cities author and star of the History Channel’s long-running show Ancient Aliens, takes us to the mysterious ruins in the mountains of Peru and Bolivia in search of ancient technology and the secrets of megalith building. In his new book, packed with photos and diagrams, Childress examines the amazing stonecutting at Puma Punku, a site neighboring the ancient ruins of Tiwanaku near Lake Titicaca in Bolivia. He looks at whether the so-called “Inca walls”-found in Cuzco and at other sites such as Sacsayhuaman, Ollantaytambo and Machu Picchu-were really made by the Incas. The evidence seems to support the idea that they were actually constructed by a ...
