Faraday, Maxwell, and the Electromagnetic Field: How Two Men Revolutionized Physics
by Basil Mahon Nancy ForbesThe story of two brilliant nineteenth-century scientists who discovered the electromagnetic field, laying the groundwork for the amazing technological and theoretical breakthroughs of the twentieth centuryTwo of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by forty years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.The authors, veteran science writers with special expertise in physics and engineering, have created a lively narrative that interweaves rich biographical detail from each man's life with clear explanations of their scientific accomplishments. Faraday was an autodidact, who overcame class prejudice and a lack of mathematical training to become renowned for his acute powers of experimental observation, technological skills, and prodigious scientific imagination. James Clerk Maxwell was highly regarded as one of the most brilliant mathematical physicists of the age. He made an enormous number of advances in his own right. But when he translated Faraday's ideas into mathematical language, thus creating field theory, this unified framework of electricity, magnetism and light became the basis for much of later, 20th-century physics.Faraday's and Maxwell's collaborative efforts gave rise to many of the technological innovations we take for granted today - from electric power generation to television, and much more. Told with panache, warmth, and clarity, this captivating story of their greatest work - in which each played an equal part - and their inspiring lives will bring new appreciation to these giants of science.
Farewell to Reality: How Fairytale Physics Betrays The Search For Scientific Truth
by Jim BaggottFrom acclaimed science author Jim Baggot, a lively, provocative, and &“intellectually gratifying&” critique of modern theoretical physics (The Economist). In this stunning new volume, Jim Baggott argues that there is no observational or experimental evidence for many of the ideas of modern theoretical physics: super-symmetric particles, superstrings, the multiverse, the holographic principle, or the anthropic cosmological principle. These theories are not only untrue, it is not even science. It is fairy-tale physics: fantastical, bizarre and often outrageous, perhaps even confidence-trickery. This book provides a much-needed antidote. Informed, comprehensive, and balanced, it offers lay readers the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy. With its engaging portraits of many central figures of modern physics, including Paul Davies, John Barrow, Brian Greene, Stephen Hawking, and Leonard Susskind, it promises to be essential reading for all readers interested in what we know and don''''t know about the nature of the universe and reality itself.
Farewell to Reality: How Fairytale Physics Betrays the Search for Scientific Truth
by Jim BaggottModern physics is heady stuff. It seems that barely a week goes by without some new astounding science story; some revelation about hidden dimensions, multiple universes, the holographic principle or incredible cosmic coincidences. But is it true? What evidence do we have for super-symmetric squarks', or superstrings vibrating in an 11-dimensional space-time? How do we know that we live in a multiverse? How can we tell that the universe is a hologram projected from information encoded on its boundary? Doesn't this sound like a fairy story?In Farewell to Reality Jim Baggott asks whether all that we currently know about the universe is based upon science or fantasy. In addition he wonders whether these high priests of fairy tale physics - such as John Barrow, Paul Davies, David Deutsch, Brian Greene, Stephen Hawking, Michio Kaku, Gordon Kane and Leonard Susskind - are the emperor's latest tailors.Praise for Jim Baggott:A shimmering tour d'horizon. Quantum theory may deny us the possibility of properly comprehending physical reality, but Baggott's account is smart and consoling. Kirkus Reviews.Jim Baggott's inspired - and inspiring - idea of presenting the history of quantum physics in terms of 40 key moments works both as an introduction for the uninitiated and as a refresher for anyone who thinks they know the story. John Gribbin.I never read such a good, comprehensive account as Jim Baggott's...highly recommended. A.N. Wilson.The best popular science book of the year to date by far. popularscience.co.uk

Farm Management In Peasant Agriculture
by Michael CollinsonFirst published in 1972, Farm Management in Peasant Agriculture remains the only detailed discussion of on-site research techniques for economists working on the development of small-holder agriculture in Africa. Part 1 describes the conditions of the agricultural sector within which the African peasant farmer must operate, and then outlines an approach to farm management tailored to those conditions. Part 2 sets out the research planning and investigation tasks implied by the approach. Survey techniques, as well as the value of a pre-survey for understanding general attributes of a farm system, are reviewed, and alternative data-collection methods are elaborated. Part 3 shows how research data can be used in planning content for extension programs. Dr. Collinson concludes with the details of a planning method that interpolates changes in farm practice into a model of the existing farm system and that projects a sequence of changes, representing a sequence of extension content, on the basis of farmer acceptability.

Farm animal proteomics
by David Eckersall André De Almeida Pedro RodriguesProteomics is a field with growing interest in almost every area of life sciences. Proteomic techniques, along with potential and obtained results have long been key components of biomedical and pharmaceutical research. In agriculture, animal and veterinary research however, use of proteomics is still limited, despite the large number of potential applications. As a result, there is a pressing need for wider use and dissemination of proteomics in animal and veterinary science research. This book meets this need by bridging the gap between experts in the technology of proteomics and those at the forefront of research into many facets of animal physiology and pathophysiology. The book encompasses a wide range of topics: from muscle and meat proteomics to acute phase proteins and proteomics in aquaculture, to name but a few. The book summarily presents the state of the art in farm animal proteomics research in Europe, providing readers with interesting examples of the applications of this set of advanced technologies as well as useful contact details of colleagues with expertise in the field. The book will be of interest to scientists at the cutting edge of animal and veterinary research who are currently, or are considering, analytical investigation and identification of protein in animal tissue and in pathogens in health and disease. Furthermore the book will provide an insight for proteomic specialists in demonstrating the breadth of applications that their technology can have in animal and food research.
Farm animal proteomics 2013
by David Eckersall Mangesh Bhide Saskia Dolinska Elena Bencurova Patrik Mlynarcik Miroslava Vincova André De AlmeidaProteomics may be defined as the large-scale study of the proteome, i.e. a set of proteins being expressed in a certain fluid, tissue, organ or organism. Although still of limited and restricted use in most areas of farm animal and veterinary research, proteomics potential is unequivocal holding a significant promise in applications such as vaccine and drug development, animal product quality, physiology or toxicology. Nevertheless, proteomics use has been growing steadily during the last 2-3 years and, as time goes by; proteomics-based studies are more and more common, not just to scientists but to the general public, unraveling their full potential. This book reflects the will of a group of scientists that merge innovation with excellence of research and to whom the dissemination of knowledge and innovation through cooperation is a key essential point. It will be of interest to scientists at the early stages of their careers as well as to researchers well established in the field and to whom proteomics may be the necessary next step towards more in-depth research activities. By providing a collection of diverse scientific interests, Farm Animal Proteomics 2013 is also a witness to the vitality of the area and the importance it holds to animal and food research, to science, industry, government agencies, the consumer and ultimately the society as a whole.
Farm-level Modelling: Techniques, Applications and Policy
by Paul Wilson Maria Espinosa Michael Michael David David Stephen Hynes Sergio Gomez y Paloma Patrick Abbot Maria Maria Arnaud Arnaud Stephen Stephen Filippo Arfini Michele Michele César Revoredo-Giha Cathal Cathal Pavel Pavel Bruce Bruce Wei Wei Wei Wei Thomas Thomas Roberto Solazzo Mario Veneziani Patrick Gillespie Fiona Thorne Thia Hennessy Vera Eory Jinxiu Ding Dr Weiwei Wang Eleonore Guillem Dave Murray-Rust Joana Guimarães Ferreira Alexander GochtAgriculture is the product of a complex mixture of behavioural, biophysical and market drivers. Understanding how these factors interact to produce crops and livestock for food has been the focus of economic investigation for many years. The advent of optimisation algorithms and the exponential growth in computing technology has allowed significant growth in mathematical modelling of the dynamics of agricultural systems. The complexity of approaches has grown in parallel with the availability of data at increasingly finer resolutions. Farm-level models have been widely used in agricultural economic studies to understand how farmers and land owners respond to market and policy levers. This book provides an in-depth description of different methodologies and techniques currently used in farm-level modelling. While giving an overview of the theoretical grounding behind the models, an applied approach is also used. Case studies range from the application of modelling to policy reforms and the subsequent impacts on rural communities and food supply. This book also provides descriptions of the use of farm-level models in much wider fields such as aggregation and linking with sectoral models. Its purpose is to show the reader the methods that have been employed to inform decision-makers about how to improve the economic, social and environmental goals required to achieve the aims of multidimensional policy.
Farmacology: Total Health from the Ground Up
by Daphne MillerWhat can good farming teach us about nurturing ourselves?In Farmacology, practicing family physician and renowned nutrition explorer Daphne Miller brings us beyond the simple concept of "food as medicine" and introduces us to the critical idea that it's the farm where that food is grown that offers us the real medicine.By venturing out of her clinic and spending time on seven family farms, Miller uncovers all the aspects of farming—from seed choice to soil management—that have a direct and powerful impact on our health. Bridging the traditional divide between agriculture and medicine, Miller shares lessons learned from inspiring farmers and biomedical researchers and weaves their insights and discoveries with stories from her patients. The result is a compelling new vision for sustainable healing and a treasure trove of farm-to-body lessons that have immense value in our daily lives.In Farmacology you will meet: a vegetable farmer in Washington state who shows us how the principles he uses to rejuvenate his soil apply just as well to our own bodies. a beef farmer in Missouri who shows how a holistic cattle-grazing method can grow resilient calves and resilient children. an egg farmer in Arkansas who introduces us to the counterintuitive idea that sometimes stresses can keep us productive and healthy. a vintner in Sonoma, California, who reveals the principles of Integrated Pest Management and helps us understand how this gentler approach to controlling unwanted bugs and weeds might be used to treat invasive cancers in humans. a farmer in the Bronx who shows us how a network of gardens offers health benefits that extend far beyond the nutrient value of the fruits and vegetables grown in the raised beds. an aromatic herb farmer back in Washington who teaches us about the secret chemical messages we exchange with plants that can affect our mood and even keep us looking youthful.In each chapter, Farmacology reveals the surprising ways the ecology of our bodies and the ecology of our farms are intimately linked. This is a paradigm-changing adventure that has huge implications for our personal health and the health of the planet.

Farmers' Crop Varieties and Farmers' Rights: Challenges in Taxonomy and Law (Issues in Agricultural Biodiversity)
by Michael HalewoodOver the last 50 years there has been a growing appreciation of the important role that farmers play in the development and conservation of crop genetic diversity, and the contribution of that diversity to agro-ecosystem resilience and food security. This book examines policies that aim to increase the share of benefits that farmers receive when others use the crop varieties that they have developed and managed, i.e., ‘farmers varieties’. In so doing, the book addresses two fundamental questions. The first question is ‘how do farmer management practices – along with other factors such as environment and the breeding systems of plants – affect the evolution and maintenance of discrete farmers’ varieties?’ The second question is ‘how can policies that depend on being able to identify discrete plant varieties accommodate the agricultural realities associated with the generation, use and maintenance of farmers’ varieties?’ This focus on discreteness is topical because there are no fixed, internationally recognized taxonomic or legal definitions of farmers’ varieties. And that presents a challenge when developing policies that involve making specific, discrete farmers’ varieties the subject of legal rights or privileges. The book includes contributions from a wide range of experts including agronomists, anthropologists, geneticists, biologists, plant breeders, lawyers, development practitioners, activists and farmers. It includes case studies from Asia, Africa, Latin America and Europe where, in response to a diversity of contributing factors, there have been efforts to develop policies that provide incentives or rewards to farmers as stewards of farmers’ varieties in ways that are sensitive to the cultural, taxonomic and legal complexities involved. The book situates these initiatives in the context of the evolving discourse and definition of ‘farmers' rights’, presenting insights for future policy initiatives.
Farming Systems Research into the 21st Century: The New Dynamic
by Ika Darnhofer Benoît Dedieu David GibbonFarming Systems Research has three core characteristics: it builds on systems thinking, it depends on the close collaboration between social and biophysical sciences, and it relies on participation to build co-learning processes. Farming Systems Research posits that to contribute towards sustainable rural development, both interdisciplinary collaborations and local actor engagement are needed. Together, they allow for changes in understanding and changes in practices. This book gives an overview of the insights generated in 20 years of Farming Systems Research. It retraces the emergence and development of Farming Systems Research in Europe, summarises the state-of-the-art for key areas, and provides an outlook on new explorations, especially those tackling the dynamic nature of farming systems and their interaction with the natural environment and the context of action.
Farming Systems and Sustainable Agriculture in the Himalaya (Sustainable Development Goals Series)
by Vishwambhar Prasad SatiThe farming system in the Central Himalayan Region is distinctive and unique, mainly focusing on the cultivation of traditional subsistence cereal crops. The agrobiodiversity in this region is rich, with the Central Himalaya growing numerous cultivars and crop races. The practice of cultivating many crops or cultivars in a single field is known as the 'Barahnaja System.' Another peculiar system is the Sar/Sari system, where different crops grow in the two Sars during the same seasons, with one Sar left fallow for six months while the other grows crops. This century-old farming method involves plowing fields with oxen and using organic manure to enhance crop production and productivity. However, recent changes have been observed in the farming systems. The area under traditionally growing millets is declining. In river valleys and middle altitudes, there is a recent trend towards cultivating paddy and wheat. Unfortunately, the cultivation of temperate fruits – apple and citrus has seen a decline in terms of area, production, and productivity. Various factors are influ encing farming systems in the Central Himalaya, such as high climate variability and change, decreasing crop production and productivity, evolving food habits, and out-migration. The book contains 12 chapters illustrating introduction, land use and land cover change, cropping patterns, crop diversity and agro-ecological zones, farming systems and sustainable agriculture, climate change and its impact on agriculture, infrastructural facilities for sustainable agriculture, declining agriculture: a case study, crop productivity and suitability analyzes, agribusiness, policies and planning for sustainable agriculture, and conclusions. It serves as a valuable resource for students, academicians, researchers, policymakers, and farmers.
Farming and the Fate of Wild Nature
by Daniel Imhoff Jo Ann BaumgartnerFarming and the Fate of Wild Nature addresses an urgent and complex issue facing communities and cultures throughout the world: the need for heightened land stewardship and conservation in an era of diminishing natural resources. Agricultural lands in rural areas are being purchased for development. Water scarcities are pitting urban and development expansion against agriculture and conservation needs. The farming population is ageing and retiring, while those who remain struggle against low commodity prices, international competition, rising production costs, and the threat of disappearing subsidies. We are living amidst a major extinction crisis--much of it driven by agriculture--as well as an increasing shift toward a global urban populace. The modern diet, driven by a grain-fed livestock industry, is no longer connected with the ecosystems that support it. In international circles, experts are arguing that further intensification of agriculture (through industrialization and genetic modification) will be necessary to both feed an exploding human population and to save what is left of wild biodiversity.This book takes up where its predecessor, the award-winning Farming with the Wild, left off. Featuring a wide range of in-depth essays, articles, and other materials by such authors as Aldo Leopold, Wendell Berry, Michael Pollan, Fred Kirschenmann, and Daniel Imhoff, this book persuasively demonstrates that farm and ranch operations which coexist with wild nature are necessary to sustain biodiversity and beauty on the landscape. In fact, as this invaluable educational resource demonstrates, they are essential in the challenge of building sane, healthy, and hopeful human societies.
