The Universe as Automaton
by Klaus Mainzer Leon ChuaThis Brief is an essay at the interface of philosophy and complexity research, trying to inspire the reader with new ideas and new conceptual developments of cellular automata. Going beyond the numerical experiments of Steven Wolfram, it is argued that cellular automata must be considered complex dynamical systems in their own right, requiring appropriate analytical models in order to find precise answers and predictions in the universe of cellular automata. Indeed, eventually we have to ask whether cellular automata can be considered models of the real world and, conversely, whether there are limits to our modern approach of attributing the world, and the universe for that matter, essentially a digital reality.

The Unknown Component Problem
by Alberto Sangiovanni-Vincentelli Alan Mishchenko Alexandre Petrenko Tiziano Villa Robert K. Brayton Nina YevtushenkoThe Problem of the Unknown Component: Theory and Applications addresses the issue of designing a component that, combined with a known part of a system, conforms to an overall specification. The authors tackle this problem by solving abstract equations over a language. The most general solutions are studied when both synchronous and parallel composition operators are used. The abstract equations are specialized to languages associated with important classes of automata used for modeling systems. The book is a blend of theory and practice, which includes a description of a software package with applications to sequential synthesis of finite state machines. Specific topologies interconnecting the components, exact and heuristic techniques, and optimization scenarios are studied. Finally the scope is enlarged to domains like testing, supervisory control, game theory and synthesis for special omega languages. The authors present original results of the authors along with an overview of existing ones.

The Unnatural World: The Race to Remake Civilization in Earth's Newest Age
by David BielloWith the historical perspective of The Song of the Dodo and the urgency of Al Gore's An Inconvenient Truth, a brilliant young environmental journalist argues that we must innovate and adapt to save planet Earth.Civilization is in crisis, facing disasters of our own making on the only planet known to bear life in the vast void of the universe. We have become unwitting gardeners of the Earth, not in control, but setting the conditions under which all of life flourishes--or not. Truly, it's survival of the innovators. The Unnatural World chronicles a disparate band of unlikely heroes: an effervescent mad scientist who would fertilize the seas; a pigeon obsessive bent on bringing back the extinct; a low-level government functionary in China doing his best to clean up his city, and more. These scientists, billionaires, and ordinary people are all working toward saving the best home humanity is ever likely to have. What is the threat? It is us. In a time when a species dies out every ten minutes, when summers are getting hotter, winters colder, and oceans higher, some people still deny mankind's effect on the Earth. But all of our impacts on the planet have ushered in what qualifies as a new geologic epoch, thanks to global warming, mass extinction, and such technologies as nuclear weapons or plastics. The Unnatural World examines the world we have created and analyzes the glimmers of hope emerging from the efforts of incredible individuals seeking to change our future. Instead of a world without us, this history of the future shows how to become good gardeners, helping people thrive along with an abundance of plants, animals, all the exuberant profusion of life on Earth--a better world with us. The current era of humans need not be the end of the world--it's just the end of the world as we know it.

The Unreliable Nation: Hostile Nature and Technological Failure in the Cold War (Inside Technology)
by Edward Jones-ImhotepAn examination of how technological failures defined nature and national identity in Cold War Canada.Throughout the modern period, nations defined themselves through the relationship between nature and machines. Many cast themselves as a triumph of technology over the forces of climate, geography, and environment. Some, however, crafted a powerful alternative identity: they defined themselves not through the triumph of machines over nature, but through technological failures and the distinctive natural orders that caused them. In The Unreliable Nation, Edward Jones-Imhotep examines one instance in this larger history: the Cold War–era project to extend reliable radio communications to the remote and strategically sensitive Canadian North. He argues that, particularly at moments when countries viewed themselves as marginal or threatened, the identity of the modern nation emerged as a scientifically articulated relationship between distinctive natural phenomena and the problematic behaviors of complex groups of machines.Drawing on previously unpublished archival documents and recently declassified materials, Jones-Imhotep shows how Canadian defense scientists elaborated a distinctive “Northern” natural order of violent ionospheric storms and auroral displays, and linked it to a “machinic order” of severe and widespread radio disruptions throughout the country. Tracking their efforts through scientific images, experimental satellites, clandestine maps, and machine architectures, he argues that these scientists naturalized Canada's technological vulnerabilities as part of a program to reimagine the postwar nation. The real and potential failures of machines came to define Canada, its hostile Northern nature, its cultural anxieties, and its geo-political vulnerabilities during the early Cold War. Jones-Imhotep's study illustrates the surprising role of technological failures in shaping contemporary understandings of both nature and nation.
The Unsettling of America: Culture and Agriculture
by Wendell BerryIn "The Unsettling of America" Wendell Berry argues that good farming is a cultural development and spiritual discipline. Today's agribusiness, however, takes farming out of its cultural context and away from families, and as a nation we are thus more estranged from the land -- from the intimate knowledge, love, and care of it. Sadly, as Berry notes in the afterword to this new edition, his arguments and observations are still relevant today. We continue to suffer loss of community, the devaluation of human work, and the destruction of nature under an economics dedicated to the mechanistic pursuit of products and profits.

BosseyThis landmark volume presents the results of a comprehensive and coherent in-depth assessment of Ethiopian agriculture and draws lessons from it to generate actionable recommendations that will inform policy decisions and priority setting for agricultural transformation across Africa. Policy makers in Africa are faced with the challenges of ensuring food and nutrition security and the economic wellbeing of their rapidly growing populations while at the same time maintaining the integrity of their natural resource base. Between 2000 and 2021, 74% of the growth in overall crop production on the continent was derived from increases in land area expansion, while increases in yield contributed only 26% of the growth. This unchecked expansion of land use puts the sustainability of the natural resource base under severe pressure. Even though some countries have made substantial increases in their farm productivity over the last two decades, the overall performance for Africa is far behind other regions. For the most part, in Africa, agriculture is not fulfilling its expected functions of food and nutrition security, increased export earnings, import substitution, and raw material supply for local industries. Attempts have been made to transform African agriculture over the years, but few countries have succeeded in achieving sustainable change. Using examples from Ethiopia this book identifies the major factors for success and the root causes of underperformance, and offers evidence-based recommendations for future decision making, policy change and the creation of growth. This book: · Draws on a unique set of case studies from Ethiopia described and told from a truly African perspective. · Emphasises to policy makers in Africa that development cannot be outsourced and there are no shortcuts; it is only through consistent effort and sustained support for their agricultural research and development that positive change can be brought about. · States that past agricultural development efforts by the international community have not properly included a strong African voice, and that therefore, all future academic research, policies and strategies dealing with the continent's agriculture and food security should be formulated by Africa's own leading thinkers and experts. · Is not a polemic; its arguments are knowledge and evidence based, building a compelling picture of how agricultural development can be sustained for the future.
The Untold Stories of the Space Shuttle Program: Unfulfilled Dreams and Missions that Never Flew (Springer Praxis Books)
by Davide SivolellaIn September 1969, several months after the Apollo 11 lunar landing, President Richard M. Nixon established the Space Task Force to chart NASA’s path for the decades to come. This imaginative vision was shattered less than six months later when, on January 13, 1970, NASA Administrator Dr. Thomas Paine announced that, owing to funding cuts, only the reusable Space Shuttle could be afforded -- there would be no space station, no return to the Moon, and no missions to Mars. This is a story never before told about the missions and technologies that NASA had begun to plan but never fully realized. The book is a companion to the author’s previous two works on the Space Shuttle. Whereas the first two books showed how the Space Shuttle flew in space and what the program accomplished, this book explains what more the Space Shuttle could have achieved and how the space transportation system could have further matured if circumstances had been otherwise. A final chapter also discusses how some of these plans might be resurrected in future programs.

The Upright Thinkers: The Human Journey from Living in Trees to Understanding the Cosmos
by Leonard MlodinowA few million years ago, our ancestors came down from the trees and began to stand upright, freeing our hands to create tools and our minds to grapple with the world around us. Leonard Mlodinow takes us on a passionate and inspiring tour through the exciting history of human progress and the key events in the development of science. In the process, he presents a fascinating new look at the unique characteristics of our species and our society that helped propel us from stone tools to written language and through the birth of chemistry, biology, and modern physics to today's technological world. Along the way he explores the cultural conditions that influenced scientific thought through the ages and the colorful personalities of some of the great philosophers, scientists, and thinkers: Galileo, who preferred painting and poetry to medicine and dropped out of university; Isaac Newton, who stuck needlelike bodkins into his eyes to better understand changes in light and color; and Antoine Lavoisier, who drank nothing but milk for two weeks to examine its effects on his body. Charles Darwin, Albert Einstein, Werner Heisenberg, and many lesser-known but equally brilliant minds also populate these pages, each of their stories showing how much of human achievement can be attributed to the stubborn pursuit of simple questions (why? how?), bravely asked. The Upright Thinkers is a book for science lovers and for anyone interested in creative thinking and in our ongoing quest to understand our world. At once deeply informed, accessible, and infused with the author's trademark wit, this insightful work is a stunning tribute to humanity's intellectual curiosity. (With black-and-white illustrations throughout.)From the Hardcover edition.

The Urban Household Energy Transition: Social and Environmental Impacts in the Developing World
by Douglas F. Barnes William F. Hyde Kerry KrutillaAs cities in developing countries grow and become more prosperous, energy use shifts from fuelwood to fuels like charcoal, kerosene, and coal, and, ultimately, to fuels such as liquid petroleum gas, and electricity. Energy use is not usually considered as a social issue. Yet, as this book demonstrates, the movement away from traditional fuels has a strong socio-economic dimension, as poor people are the last to attain the benefits of using modern energy. The result is that health risks from the continued use of wood fuel fall most heavily on the poor, and indoor pollution from wood stoves has its greatest effect on women and children who cook and spend much more of their time indoors. Barnes, Krutilla, and Hyde provide the first worldwide assessment of the energy transition as it occurs in urban households, drawing upon data collected by the World Bank Energy Sector Management Assistance Programme (ESMAP). From 1984-2000, the program conducted over 25,000 household energy surveys in 45 cities spanning 12 countries and 3 continents. Additionally, GIS mapping software was used to compile a biomass database of vegetation patterns surrounding 34 cities. Using this rich set of geographic, biological, and socioeconomic data, the authors describe problems and policy options associated with each stage in the energy transition. The authors show how the poorest are most vulnerable to changes in energy markets and demonstrate how the collection of biomass fuel contributes to deforestation. Their book serves as an important contribution to development studies, and as a guide for policymakers hoping to encourage sustainable energy markets and an improved quality of life for growing urban populations.
