On The Scale Of The World

In the tradition of illustrated science bestsellers, like Thing Explainer andharkening back to the classic film The Powers of Ten, this unique, fully-illustrated, four-color book explores and visualizes the concept of scale in our universe. In Magnitude, Kimberly Arcand and Megan Watzke take us on an expansive journey to the limits of size, mass, distance, time, temperature in our universe, from the tiniest particle within the structure of an atom to the most massive galaxy in the universe; from the speed at which grass grows (about 2 to 6 inches a month) to the speed of light. Fully-illustrated with four-color drawings and infographics throughout and organized into sections including Size and Amount (Distance, Area, Volume, Mass, Time, Temperature), Motion and Rate (Speed, Acceleration, Density, Rotation), and Phenomena and Processes (Energy, Pressure, Sound, Wind, Computation), Magnitude shows us the scale of our world in a clear, visual way that our relatively medium-sized human brains can easily understand.

Kings, aristocrats, peasants, and the Church are among the shared features of most early medieval societies. However, these also varied dramatically in time and space. Can petty regional kings, for instance, be compared to those in charge of a whole empire? Scale is a crucial factor in modelling, explaining, and conceptualizing the past. Furthermore, many issues that historians and archaeologists treat independently can be theorized together as processes of scale decrease or increase: the appearance of complex societies, the rise and collapse of empires, changing world-systems, and globalization. While a subject of much discussion in fields such as ecology, geography, and sociology, scale is rarely theorized by archaeologists and historians. This book highlights the potential of the concepts of scale and scale change for comparing and explaining medieval socio-spatial processes. It integrates regional and temporal variations in the fragmentation of the Roman world and the emergence of medieval polities, which are often handled separately by late antique and early medieval specialists. The result of a three-year research project, the nine case studies in this volume offer fresh insights into early medieval rural society while combining their individual subjects to generate a wider explanatory framework.

“If you care about climate change, John Doerr’s new book, Speed & Scale, offers concrete steps that we can all take to make a difference.” - Barack Obama With clear-eyed realism and an engineer’s precision, Doerr lays out the practical actions, global ambitions, and economic investments we need to avert climate catastrophe. Guided by real-world solutions, Speed & Scale features unprecedented, firsthand accounts from climate leaders such as Laurene Powell Jobs, Christiana Figueres, Al Gore, Mary Barra, John Kerry, and dozens of other intrepid policymakers, innovators, and scientists. In Speed & Scale, Doerr presents a compelling 10-step plan to cut greenhouse gas emissions to net zero by 2050–the global goal we need to reach to ensure a livable Earth for generations to come. From electrifying our energy grid to fixing our global food supply chain to capturing carbon from the air, Speed & Scale contains practical solutions for policymakers and entrepreneurs alike. As the world confronts an urgent climate crisis, Doerr reminds us that it is also the greatest economic opportunity of our lifetimes. Whether you’re a climate scientist or someone striving to make a difference in your local community, this book will help you to activate the sustainable solutions the world urgently needs. Praise for Speed & Scale: “Everybody should get Speed & Scale by John Doerr.” - Meryl Streep “A practical guide for participation in decarbonizing the global economy, a task as challenging as it is urgent.” - Christiana Figueres

"This is science writing as wonder and as inspiration." —The Wall Street Journal Wall Street Journal From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in. Visionary physicist Geoffrey West is a pioneer in the field of complexity science, the science of emergent systems and networks. The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science: West found that despite the riotous diversity in mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism’s body. West’s work has been game-changing for biologists, but then he made the even bolder move of exploring his work’s applicability. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. Recently, West has applied his revolutionary work to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune.

The importance of fisheries is not lost in the global policy arena. What is often overlooked in the general discourse, however, is the significant difference between small-and large-scale fisheries. Major rethinking about all aspects of small-scale fisheries is required, including their contribution to catches, employment, livelihood, food security and conservation. This book is a collection of essays about the diverse, complex and dynamic contexts that characterize small-scale fisheries around the world. The essays highlight the strengths, capacity, motivation and contributions associated with this fishing sector. They remind us that solutions and opportunities for the viability and sustainability of small-scale fisheries can be found, once the issues are understood from a holistic perspective and possible options, including inventive governance arrangements, are fully explored. The authors are scientists and practitioners who work in small-scale fisheries in various parts of the world, many of whom participated at the first World Small-Scale Fisheries Congress (WSFC), held in Bangkok in October 2010, and are members of the global research network for the future of small-scale fisheries, Too Big To Ignore. The editor, Ratana Chuenpagdee, the initiator of the WSFC, is Canada Research Chair in Natural Resource Sustainability and Community Development at Memorial University of Newfoundland, Canada.

Geographical scale is a central concept enabling us to make sense of the world we inhabit. Amongst other things, it allows us to declare one event or process a national one and another a global or regional one. However, geographical scales and how we think about them are profoundly contested, and the spatial resolution at which social processes take place – local, regional or global – together with how we talk about them has significant implications for understanding our world. Scale provides a structured investigation of the debates concerning the concept of scale and how various geographical scales have been thought about within critical social theory. Specifically, the author examines how the scales of the body, the urban, the regional, the national, and the global have been conceptualized within Geography and the social sciences more broadly. The first part of the book provides a comprehensive overview of how different theoretical perspectives have regarded scale, especially debates over whether scales are real things or merely mental contrivances and/ or logical devices with which to think, as well as the consequences of thinking of them in areal versus in networked terms. The subsequent five chapters of the book then each takes a particular scale: the body; the urban; the regional; the national; the global and explores how it has been conceptualized and represented discursively for political and other purposes. A brief conclusion draws the book together by posing a number of questions about scale which emerge from the foregoing discussion. The first single-author volume ever written on the subject of geographical scale, this book provides a unique overview in pushing understandings of scale in new and original directions. The accessible text is complimented by didactic boxes, and Scale serves as a valuable pedagogical reference for undergraduate and postgraduate audiences wishing to become familiar with such theoretical issues.

This book constitutes the thoroughly refereed post-proceedings of the 15th International Workshop on Theoretic Foundations of Computer Vision, held as a Dagstuhl Seminar in Dagstuhl Castle, Germany, in June/July 2011. The 19 revised full papers presented were carefully reviewed and selected after a blind peer-review process. The topic of this Workshop was Outdoor and Large-Scale Real-World Scene Analysis, which covers all aspects, applications and open problems regarding the performance or design of computer vision algorithms capable of working in outdoor setups and/or large-scale environments. Developing these methods is important for driver assistance, city modeling and reconstruction, virtual tourism, telepresence, and motion capture.
