Comets II situates comet science in the global context of astrophysics for the first time by beginning with a series of chapters that describe the connection between stars and planets. It continues with a presentation of the formation and evolution of planetary systems, enabling the reader to clearly see the key role played in our own solar system by the icy planetesimals that were the seeds of the giant planets and transneptunian objects.
The book presents the key results obtained during the 1990s, in particular those collected during the apparition of the exceptional comets C/Hyakutake and C/Hale-Bopp in 1996-1997. The latest results obtained from the in situ exploration of comets P/Borrelly and P/Wild 2 are also discussed in detail.
Each topic of is designed to be accessible to students or young researchers looking for basic, yet detailed, complete and accurate, information on comet science. With its emphasis on the origin of theories and the future of research, Comets II will enable scientists to make connections across disciplinary boundaries and will set the stage for discovery and new understanding in the coming years.
We are connected to distant space and time not only by our imaginations but also through a common cosmic heritage. Emerging now from modern science is a unified scenario of the cosmos, including ourselves as sentient beings, based on the time-honored concept of change. From galaxies to snowflakes, from stars and planets to life itself, we are beginning to identify an underlying ubiquitous pattern penetrating the fabric of all the natural sciences--a sweepingly encompassing view of the order and structure of every known class of object in our richly endowed universe.
This is the subject of Eric Chaisson's new book. In Cosmic Evolution Chaisson addresses some of the most basic issues we can contemplate: the origin of matter and the origin of life, and the ways matter, life, and radiation interact and change with time. Guided by notions of beauty and symmetry, by the search for simplicity and elegance, by the ambition to explain the widest range of phenomena with the fewest possible principles, Chaisson designs for us an expansive yet intricate model depicting the origin and evolution of all material structures. He shows us that neither new science nor appeals to nonscience are needed to understand the impressive hierarchy of the cosmic evolutionary story, from quark to quasar, from microbe to mind.
China and Albert Einstein is the first extensive study in English or Chinese of China’s reception of the celebrated physicist and his theory of relativity. Tracing the influence of Jesuit missionaries in the seventeenth century and Western missionaries and educators in the nineteenth and twentieth centuries, as they introduced key concepts of Western physical science and paved the way for Einstein’s radical new ideas, Danian Hu shows us that Chinese receptivity was fostered by the trickle of Chinese students sent abroad for study beginning in the mid-nineteenth century and by the openness of the May Fourth Movement (1916–1923).
In a series of biographical studies of Chinese physicists, Hu describes the Chinese assimilation of relativity and explains how Chinese physicists offered arguments and theories of their own. Hu’s account concludes with the troubling story of the fate of foreign ideas such as Einstein’s in the Chinese Cultural Revolution (1966–1976), when the theory of relativity was denigrated along with Einstein’s ideas on democracy and world peace.
China and Albert Einstein is an important contribution to Einstein studies and a landmark work in the history of Chinese science.
In this critically acclaimed book, first published in 1988 and now reprinted in paperback, scientist and author Paul Davies explains how recent scientific advances are transforming our understanding of the emergence of complexity and organization in the universe.
Melding a variety of ideas and disciplines from biology, fundamental physics, computer science, mathematics, genetics, and neurology, Davies presents his provocative theory on the source of the universe's creative potency. He explores the new paradigm (replacing the centuries-old Newtonian view of the universe) that recognizes the collective and holistic properties of physical systems and the power of self-organization. He casts the laws in physics in the role of a "blueprint," embodying a grand cosmic scheme that progressively unfolds as the universe develops.
Challenging the viewpoint that the physical universe is a meaningless collection of particles, he finds overwhelming evidence for an underlying purpose: "Science may explain all the processes whereby the universe evolves its own destiny, but that still leaves room for there to be a meaning behind existence."
Albert Einstein’s theory of general relativity describes the effect of gravitation on the shape of space and the flow of time. But for more than four decades after its publication, the theory remained largely a curiosity for scientists; however accurate it seemed, Einstein’s mathematical code—represented by six interlocking equations—was one of the most difficult to crack in all of science. That is, until a twenty-nine-year-old Cambridge graduate solved the great riddle in 1963. Roy Kerr’s solution emerged coincidentally with the discovery of black holes that same year and provided fertile testing ground—at long last—for general relativity. Today, scientists routinely cite the Kerr solution, but even among specialists, few know the story of how Kerr cracked Einstein’s code.
Fulvio Melia here offers an eyewitness account of the events leading up to Kerr’s great discovery. Cracking the Einstein Code vividly describes how luminaries such as Karl Schwarzschild, David Hilbert, and Emmy Noether set the stage for the Kerr solution; how Kerr came to make his breakthrough; and how scientists such as Roger Penrose, Kip Thorne, and Stephen Hawking used the accomplishment to refine and expand modern astronomy and physics. Today more than 300 million supermassive black holes are suspected of anchoring their host galaxies across the cosmos, and the Kerr solution is what astronomers and astrophysicists use to describe much of their behavior.
By unmasking the history behind the search for a real world solution to Einstein’s field equations, Melia offers a first-hand account of an important but untold story. Sometimes dramatic, often exhilarating, but always attuned to the human element, Cracking the Einstein Code is ultimately a showcase of how important science gets done.
Day in and day out, cosmic rays from the far reaches of space pass through our bodies, yet modern astrophysics has still to unlock all their secrets. Though many details about cosmic rays remain enigmatic, next to electromagnetic radiation they convey more information about the universe beyond the solar system than any other source. They provide us with information about energetic explosions elsewhere in our galaxy and perhaps beyond, and they tell us a great deal about the contents of our own galaxy, through which they pass in reaching us. Illustrating the beautiful symmetry of nature, they shed light on the tiny dimensions of atomic nuclei as well as the immense scale of galaxies.
Friedlander's engaging tale of this peculiar rain of charged particles begins with their discovery early in this century and goes on to describe impressive attempts by a special breed of scientists--sometimes engaging in swashbuckling science at its most adventurous--to fill in the gaps in our knowledge. The central question is: Where do cosmic rays come from? Some scientists maintain that supernovas, much more massive than our sun, are largely responsible for generating them. Most of them probably originate within our Milky Way galaxy, but a few (the most energetic ones) appear to come from a much greater distance. But we still have much to learn about their origin.
The book describes scientists studying cosmic rays by all sorts of methods: satellites, space probes, high-altitude balloons and airplanes-even giant detectors two miles beneath the earth's surface. Their ingenious investigations have yielded startling insights about nature--as well as an inordinately large number of Nobel Prizes. Michael Friedlander, for many years a principal researcher of cosmic radiation, masterfully portrays how a perfect marriage between pure and applied science has forged new understandings of our physical world. This uncommonly lucid history, richly illustrated with more than 50 drawings and photographs, touches the astronomer within each of us who yearns to explore one of the great mysteries of the universe.
People living in the Great Lakes region are already feeling the effects of a changing climate. Shifts in seasonal temperatures and precipitation patterns could have dramatic impacts on the economy, ecology, and quality of life. In this illuminating and thorough volume, leading scholars address the challenge of preparing for climate change in the region, where decision makers from various sectors—government, agriculture, recreation, and tourism—must increasingly be aware of the need to incorporate climate change into their short- and long-term planning. The chapters in this revealing book, written by some of the foremost climate change scholars in North America, outline the major trends in the climate of the Great Lakes region, how humans might cope with the uncertainty of climate change impacts, and examples of on-the-ground projects that have addressed these issues.
Questions surrounding the issue of climate change are evolving from "Is it happening?" to "What can be done about it?" The primary obstacles to addressing it at this point are not scientific but political and economic; nonetheless a quick resolution is unlikely.
Ignorance and confusion surrounding the issue -- including a lack of understanding of climate science, its implications for the environment and society, and the range of policy options available -- contributes to the political morass over dealing with climate change in which we find ourselves. Climate Change Policy addresses that situation by bringing together a wide range of new writings from leading experts that examine the many dimensions of the topics most important in understanding climate change and policies to combat it. Chapters consider:
Climate Change is the report of Working Group III of the Intergovernmental Panel on Climate Change (IPCC), established in 1988 by the World Meteorological Organization and UNEP to address the threat of global warming on an international scale.
Climate Affairs sets forth in a concise primer the base of knowledge needed to begin to address questions surrounding the unknown impacts of climate change. In so doing, it outlines a new approach to understanding the interactions among climate, society, and the environment. Chapters consider:
Challenge of Global Warming examines the causes and effects of global climate change.
The demonstrations capture interest, teach, inform, fascinate, amaze, and perhaps, most importantly, involve students in chemistry. Nowhere else will you find books that answer, "How come it happens? . . . Is it safe? . . . What do I do with all the stuff when the demo is over?"
Shakhashiri and his collaborators offer 282 chemical demonstrations arranged in 11 chapters. Each demonstration includes seven sections: a brief summary, a materials list, a step-by-step account of procedures to be used, an explanation of the hazards involved, information on how to store or dispose of the chemicals used, a discussion of the phenomena displayed and principles illustrated by the demonstration, and a list of references.
Color and light are the focus of this long-awaited fifth volume in the Chemical Demonstrations series, which describes demonstrations that effectively communicate science to both students and general audiences. Using full color illustrations, the book provides meticulous instructions for safely demonstrating colorful phenomena and illustrating scientific principles. A rich introductory section explores the science of color and light, outlines the chemical processes of vision, and explains what happens when visual information enters the human eye and is perceived by the brain. With more than fifty demonstrations and multiple procedures included, this volume offers abundant opportunities to arouse and sustain interest in science for both classroom and public presentations.
Each demonstration includes:
• a brief description of the demonstration
• a materials list
• a step-by-step account of procedures to be used
• an explanation of the potential hazards involved
• information on safely storing and disposing the chemicals used
• a full discussion of the phenomena displayed and principles illustrated
• a list of references.
Created by acclaimed chemists and science educators Bassam Shakhashiri and his collaborators Rodney Schreiner and Jerry Bell, these demonstrations make an impressive addition to the earlier volumes, which have been lauded for guiding teachers and scientists in effectively communicating science. Like all volumes in the series, Volume 5 communicates chemistry using pedagogical knowledge to enhance the effectiveness of demonstrations to all audiences.
An easy-to-read geological history of the amazing red rock landscapes in southeastern Utah.
Towering red buttes, plunging canyon walls, domes, pinnacles, spires, ten thousand strangely carved forms—what visitor hasn’t marveled at the land of rock in southeastern Utah that is Canyonlands Country?
Canyonlands Country offers a unique geological history of this awesome landscape, in language understandable by the non-geologist. The story is as strange and fascinating as the land itself. Each exposed rock layer has a different geologic history: one is a stream deposit, another is an ancient field of dunes, another was deposited by shallow tropic seas. The Green and Colorado Rivers began carving canyons thirty million years ago, but to understand such relatively recent events Canyonlands Country takes us on a journey of two billion years.
Tours include Arches National Park, Island in the Sky, Needles District, The Maze and Elaterite Basin, Labyrinth and Stillwater Canyons, Meander Canyon, and Cataract Canyon.
This engaging illustrated guidebook reveals the fascinating mosses and lichens that homeowners, outdoorspeople, and nature lovers encounter every day in Ohio and the Midwest.
In this guide to the most common and distinctive moss, liverwort, and lichen species in Ohio, readers will find concise physical descriptions, facts about natural history and ecology, and tips to distinguish look-alike species, all presented in a friendly, conversational tone.
Featuring detailed photographs of the plant and plantlike species in their natural settings, the book covers 106 mosses, thirty liverworts, and one hundred lichens and offers several avenues to match a specimen to its description page. “Where They Grow” chapters spotlight species commonly encountered on field outings, and field keys to help readers quickly identify unfamiliar samples.
While designed primarily as an identification tool, this guide also frames moss and lichen spotting in a scientific context. The two main sections—bryophytes and lichens—detail their respective taxonomic kingdoms, explain their life cycles and means of reproduction, and illustrate variation in the traits used for identification. The book is an introduction to the biology of these intriguing but too-often-overlooked organisms and a means to enjoy, identify, and catalog the biodiversity all around us.
For years environmentalists thought natural resources could be best protected by national legislation. But the poor outcomes of this top-down policy have led conservation professionals today to regard local communities as the agents of conservation efforts. According to a recent survey, more than fifty countries report that they pursue partnerships with local communities in an effort to protect their forests. Despite the recent popularity of a community-based approach, the concept of community rarely receives the attention it should get from those concerned with resource management. This balanced volume redresses the situation, demonstrating both the promise and the potential dangers of community action.
Although the contributors advocate community-based conservation, they examine the record with a critical eye. They pay attention to the concrete political contexts in which communities emerge and operate. Understanding the nature of community requires understanding the internal politics of local regions and their relationship to external forces and actors. Especially critical are issues related to ethnicity, gender, and the state.
Since the earliest days of our nation, new communications and transportation networks have enabled vast changes in how and where Americans live and work. Transcontinental railroads and telegraphs helped to open the West; mass media and interstate highways paved the way for suburban migration. In our own day, the internet and advanced logistics networks are enabling new changes on the landscape, with both positive and negative impacts on our efforts to conserve land and biodiversity. Emerging technologies have led to tremendous innovations in conservation science and resource management as well as education and advocacy efforts. At the same time, new networks have been powerful enablers of decentralization, facilitating sprawling development into previously undesirable or inaccessible areas.
Conservation in the Internet Age offers an innovative, cross-disciplinary perspective on critical changes on the land and in the field of conservation. The book:
The Wildlands Project is a far-reaching effort by scientists and activists to develop better ways of protecting nature, wilderness, and biodiversity. Its ultimate goal is to establish an effective network of nature reserves throughout North America -- core conservation areas linked by corridors, and buffered, where appropriate, by lands that may also serve economic objectives.
Continental Conservation represents the work of thirty leading experts-including Michael Soulé, John Terborgh, Reed Noss, Paul Paquet, Dan Simberloff, Rodolfo Dirzo, J. Michael Scott, Andrew Dobson, and others -- brought together by The Wildlands Project to examine the science underlying the design and management of these regional-scale networks. It provides conservationists and biologists with the latest scientific principles for protecting living nature at spatial scales that encompass entire regions and continents.
Following an opening chapter that sets the stage by introducing major themes and the scientific and policy background, the contributors:
The book ends by challenging the reader, whether scientist or advocate, to commit more time to the effort of saving nature. The authors argue that the very survival of nature is at stake, and scientists can no longer afford to stand behind a wall of austere objectivity.
Continental Conservation is an important guidebook that can serve a vital role in helping fashion a radically honest, scientifically rigorous land-use agenda. It will be required reading for scientists and professionals at all levels involved with ecosystem and land management.
The environmental movement today is at a critical crossroads. Crossroads: Environmental Priorities for the Future is an in-depth assessment of the movement's successes and failures, and also offers prescriptions for the future. It includes contributions from some of the country's top environmental leaders and activists, including Barry Commoner, Stewart Udall, William K. Reilly, Gus Speth, Jay Hair, Lois Gibbs, Michael Frome, Chuck Little, and William Futrell.
Community and public support are essential to the success of conservation and resource management programs. Often, the level of support received depends on whether or not the goals and importance of the program have been clearly explained to the public, the press, or policymakers. Without good communication, even the best programs are liable to fail.
Communication Skills for Conservation Professionals provides in-depth guidance on achieving conservation goals through better communications. It introduces communication approaches -- marketing and mass media, citizen participation, public information, environmental interpretation, and conservation education activities -- and offers scores of real-world examples and straightforward advice that will help conservationists develop the the skills they need to communicate effectively. Following an introductory chapter that provides an overview of the communication process, the book:
Communication Skills for Conservation Professionals is a much-needed contribution to the environmental literature that will play a vital role in helping scientists, managers, concerned citizens, and students to more effectively communicate their knowledge and concern about the environment, and to achieve greater professional and community success with their environmental campaigns.
Collaborative Planning for Wetlands and Wildlife presents numerous case studies that demonstrate how different communities have creatively reconciled problems between developers and environmentalists. It answers questions asked by regulators, environmentalists, and developers who seek practical alternatives to the existing case-by-case permitting process, and offers valuable lessons from past and ongoing areawide planning efforts.

A complex mosaic of post oak and blackjack oak forests interspersed with prairies, the Cross Timbers covers a north-south belt of southern Kansas, eastern Oklahoma, and North Central Texas. Home to Native Americans over several thousand years, the Cross Timbers became a barrier to westward expansion in the nineteenth century, until roads and railroads opened it up to farmers and ranchers, coal miners, and modern city developers, all of whom changed its character in far-reaching ways.
This landmark book fully describes the natural environment of the Cross Timbers and the role that people have played in transforming the region. Richard Francaviglia opens with a natural history that discusses the region's geography and geology, vegetation, and climate. He then traces the interaction of people and the landscape, from the earliest Native American inhabitants and European explorers to the developers and residents of today's ever-expanding cities and suburbs. Many historical and contemporary maps and photographs illustrate the text.
Coastal Marshes was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
The coastal regions of the United States form a highly diversified environment. In addition to sandy beaches and rocky shorelines, there are lagoons, rivers, estuaries, and marshes. The last are a dominant features of many coastal areas and serve as a transition between sea and uplands. Coastal marshes have been a zone for human development, attractive to industrial and residential building because they provide water frontage. But the public is becoming aware of the great value of these wetlands to fisheries and wildlife and to the local economy that depends on them.
This book describes coastal marshes in terms of form, function, ecology, wildlife value, and management. Robert H. Chabreck's emphasis is on the marshes of the northern coast of the Gulf of Mexico (there are 5,500 square miles of marshland in Louisiana alone), but he also deals with marshes on the Atlantic and Pacific coasts. Plant and animal communities are each given a chapter, and the book concludes with considerations of future uses and needs. The author provides references, a glossary, and a list of scientific names, along with numerous illustrations, including a section of color photographs.
For thirty years, Robert H. Chabreck has been engaged in research and management of coastal marshes and has often served as a consultant in wetland ecology. He is a professor of wildlife at Louisiana State University.
Braund presents the only annotated edition of Bernard Romans's rare and valuable 18th-century account of his observations in the southeastern United States.
Bernard Romans's A Concise Natural History of East and West Florida, William Bartram's Travels, and James Adair's History of the American Indian are the three most significant accounts of the southeastern United States published during the late 18th century. This new edition of Romans's Concise Natural History, edited by historian Kathryn Braund, provides the first fully annotated edition of this early and rare description of both the European settled areas and the adjoining Indian lands in what are now the states of Florida, Georgia, Alabama, Mississippi, and Louisiana.
Romans's purpose in producing his Concise Natural History was twofold: to aid navigators and shippers by detailing the sailing passages of the region and to promote trade and settlement in the region. To those ends, he provided detailed scientific observations on the natural history of the area, a summary of the region's political history, and an assessment of the potential for economic growth in the Floridas based on the area's natural resources.
A trained surveyor and cartographer and a self-taught naturalist, Romans supplied detailed descriptions of the region's topography and environment, including information about the climate and weather patterns, plants, animals, and diseases. He provided information about the state of scientific inquiry in the South and touched on many of the most important intellectual arguments of the day, such as the origin of the races, the practice of slavery, and the benefits and drawbacks of monopoly on trade.
In addition, Concise Natural History can be placed firmly in the genre of colonial promotional literature. Romans's book was an enthusiastic guide aimed at those seeking to establish modest holdings in the region:
"What a field is open here! . . . No country ever had such inexhaustible resources; no empire had ever half so many advantages combining in its behalf!" Romans explained how settlers should travel to the area, what they would need in terms of provisions and tools, and what it would cost to have their land surveyed. In addition to providing an abundance of practical advice, Romans also offered information about the history of earlier settlements, including the earliest and most complete account of New Smyrna near St. Augustine.
Romans also presented unique information about the various Indian tribes he encountered. In fact, historians agree that among the most useful portions of the book are Romans's descriptions of the largest Indian tribes in the 18th-century Southeast: the Creeks, Choctaws, and Chickasaws. Romans's account of the diet of the Creeks and Choctaws is one of the most complete available. And his description of the location of Choctaw village sites is one of the best sources for this information.
Northern Michigan is undergoing unprecedented changes in land use, climate, resource extraction, and species distributions. For the last hundred years, the University of Michigan Biological Station has monitored these environmental transformations. Stretching 10,000 acres along Burt and Douglas Lakes in the northern Lower Peninsula and 3,200 acres on Sugar Island near Sault Ste. Marie, Michigan, the station has played host to nearly 10,000 students and a steady stream of top scientists in the fields of biology, ecology, geology, archeology, and climatology.
The Changing Environment of Northern Michigan collects essays by some of these scientists, who lead readers on virtual field trips exploring the history of people and science at the station itself, the relations of indigenous people to the land, the geophysical history of the region, characteristics of terrestrial and aquatic ecosystems, key groups of organisms and their relations to local habitats, and perspectives on critical environmental challenges of today and their effects on the region. Accompanying the chapters are color illustrations and photographs that bring the station's pristine setting to life.
Like the station itself, the book provides a solid background for better appreciating the relationships among living and nonliving parts of northern Michigan, for anyone interested in exploring the region's forests, fields, and wetlands; wading or paddling down its rivers; or swimming or floating across its lakes.
Knute J. Nadelhoffer is Director of the University of Michigan Biological Station and Professor of Ecology and Evolutionary Biology at the University of Michigan.
Alan J. Hogg, Jr., teaches science writing at the University of Michigan as a faculty member of the Sweetland Writing Center. His Ph.D. research explored the effects of ozone and nitrogen oxides on University of Michigan Biological Station forests.
Brian A. Hazlett is Professor Emeritus of Zoology at the University of Michigan.
Working mostly alone, almost single-handedly writing 250,000 lines of computer code, Steve Grand produced Creatures®, a revolutionary computer game that allowed players to create living beings complete with brains, genes, and hormonal systems—creatures that would live and breathe and breed in real time on an ordinary desktop computer. Enormously successful, the game inevitably raises the question: What is artificial life? And in this book—a chance for the devoted fan and the simply curious onlooker to see the world from the perspective of an original philosopher-engineer and intellectual maverick—Steve Grand proposes an answer.
From the composition of the brains and bodies of artificial life forms to the philosophical guidelines and computational frameworks that define them, Creation plumbs the practical, social, and ethical aspects and implications of the state of the art. But more than that, the book gives readers access to the insights Grand acquired in writing Creatures—insights that yield a view of the world that is surprisingly antireductionist, antimaterialist, and (to a degree) antimechanistic, a view that sees matter, life, mind, and society as simply different levels of the same thing. Such a hierarchy, Grand suggests, can be mirrored by an equivalent one that exists inside a parallel universe called cyberspace.
