Heritage
Historic sites, memorials, national parks, museums...we live in an age in which heritage is ever-present. But what does it mean to live amongst the spectral traces of the past, the heterogeneous piling up of historic materials in the present? How did heritage grow from the concern of a handful of enthusiasts and specialists in one part of the world to something which is considered to be universally cherished? And what concepts and approaches are necessary to understanding this global obsession? Over the decades, since the adoption of the World Heritage Convention, various ‘crises’ of definition have significantly influenced the ways in which heritage is classified, perceived and managed in contemporary global societies. Taking an interdisciplinary approach to the many tangible and intangible ‘things’ now defined as heritage, this book attempts simultaneously to account for this global phenomenon and the industry which has grown up around it, as well as to develop a ‘toolkit of concepts’ with which it might be studied. In doing so, it provides a critical account of the emergence of heritage studies as an interdisciplinary field of academic study. This is presented as part of a broader examination of the function of heritage in late modern societies, with a particular focus on the changes which have resulted from the globalisation of heritage during the late twentieth and early twenty-first centuries. Developing new theoretical approaches and innovative models for more dialogically democratic heritage decision making processes, Heritage: Critical Approaches unravels the relationship between heritage and the experience of late modernity, whilst reorienting heritage so that it might be more productively connected with other pressing social, economic, political and environmental issues of our time.
The Sceptical Chymist
This 1661 classic defines the term "element" and asserts that all natural phenomena can be explained by the motion and organization of primary particles. 1911 edition.
Enriching the Earth
Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.
