Emigrating Beyond Earth puts space colonization into the context of human evolution. Rather than focusing on the technologies and strategies needed to colonize space, the authors examine the human and societal reasons for space colonization. They make space colonization seems like a natural step by demonstrating that if will continue the human species' 4 million-year-old legacy of adaptation to difficult new environments. The authors present many examples from the history of human expansion into new environments, including two amazing tales of human colonization - the prehistoric settlement of the upper Arctic around 5,000 years ago and the colonization of the Pacific islands around 3,000 years ago - which show that space exploration is no more about rockets and robots that Arctic exploration was about boating!
Thomas Bewick (1753-1828) is synonymous with finely crafted wood engravings of the natural world, and his instantly recognisable style influenced book illustration well into the nineteenth century. During his childhood in the Tyne valley, his two obsessions were art and nature. At fourteen, he was apprenticed to the engraver and businessman Ralph Beilby (1743-1817) with whom he later published A General History of Quadrupeds (also reissued in this series). The present work, with its text compiled from various sources, was the first practical field guide for the amateur ornithologist, inspiring also artists and writers. Each of the two volumes contains hundreds of illustrations of breathtaking beauty and precision: one for each species, neatly capturing its character in exquisite detail, interspersed with charming vignettes of country life. Volume 2, first published in 1804, covers water birds, including sandpipers, terns, grebes and guillemots.
An entertaining, enlightening, and humorous graphic narrative of the dangerous thinkers who laid the foundation of modern thought This entertaining and enlightening graphic narrative tells the exciting story of the seventeenth-century thinkers who challenged authority--sometimes risking excommunication, prison, and even death--to lay the foundations of modern philosophy and science and help usher in a new world. With masterful storytelling and color illustrations, Heretics! offers a unique introduction to the birth of modern thought in comics form--smart, charming, and often funny. These contentious and controversial philosophers--from Galileo and Descartes to Spinoza, Locke, Leibniz, and Newton--fundamentally changed the way we look at the world, society, and ourselves, overturning everything from the idea that the Earth is the center of the cosmos to the notion that kings have a divine right to rule. More devoted to reason than to faith, these thinkers defended scandalous new views of nature, religion, politics, knowledge, and the human mind. Heretics! tells the story of their ideas, lives, and times in a vivid new way. Crisscrossing Europe as it follows them in their travels and exiles, the narrative describes their meetings and clashes with each other--as well as their confrontations with religious and royal authority. It recounts key moments in the history of modern philosophy, including the burning of Giordano Bruno for heresy, Galileo's house arrest for defending Copernicanism, Descartes's proclaiming cogito ergo sum, Hobbes's vision of the "nasty and brutish" state of nature, and Spinoza's shocking Theological-Political Treatise. A brilliant account of one of the most brilliant periods in philosophy, Heretics! is the story of how a group of brave thinkers used reason and evidence to triumph over the authority of religion, royalty, and antiquity.
Talking dolphins . . . Underwater cities . . . Two-hundred-year life spans . . . Welcome to the present People have always imagined what life would be like in the future. Most of the time they've been wrong. Often they were really, really wrong. Your Flying Car Awaits looks at the most outrageous predictions from twentieth-century scientists, novelists, and social commentators, detailing the technologies and philosophies that led some great (and not so great)minds to think the ridiculous was achievable. Includes phenomenally inaccurate predictions such as: Space tourism will be ubiquitous by the year 2000Nuclear explosives will be used for commercial demolitionEngineered and man-made oceans will cover the planetWeather will be as predictable and controllable as a train schedule An eye-opening, fascinating, and endlessly entertaining collection of truly boneheaded scientific predictions from the past hundred years, Your Flying Car Awaits shines an illuminating light on the people of the previous century by examining the ridiculous theories they envisioned about this one.
Man is the best thing in the World. Nature does nothing uselessly. Aristotle There is a pleasure in the pathless woods, There is rapture on the lonely shore, There is society, where none intrudes, By the deep sea, and music in its roar: I love not Man the less, but Nature more. John Burroughs The basic purpose of development is to enlarge people's choices. The objective of development is to create an enabling environment for people to enjoy long, healthy and creative lives. Mahbub ul Hag Founder of the Human Development Report Theaimofthisbookis toprovidea compiledset ofconcepts,principles,methods and issues used for studying, designing and operating human-minding and natu- minding automation and industrial systems. The depth of presentation is suf?cient for the reader to understand the problems involved and the solution approaches, and appreciate the need of human-automation cooperative interaction, and the - portance of the efforts required for environment and ecosystem protection during any technological and development process in the society. Humans and technology are living and have to live together in a sustainable society and nature. Humans must not be viewed as components of automation and technology in the same way as machines. Automation and technology must incorporate the humans' needs and preferences, and radiate "beauty" in all ways, namely functionally, technically and humanistically. In overall, automation and technology should create comfort and give pleasure.
This volume is a compilation of the papers presented at a meeting that took place in April 1980 at the Mote Marine Laboratory, Sarasota, Florida. The meeting and this volume are outgrowths of two earlier international meetings on marine bio-acoustics that occurred in 1963 and 1966 (Tavolga 1964, 1967). The first meeting took place at the Lerner Marine Laboratory of the American Museum of Natural History, while the second meeting was at the American Museum itself, and was under the sponsorship of the Department of Animal Behavior. It is apparent that these two volumes have had immense impact on the current study of marine bio-acoustics, and particularly on fish audition. In a preliminary conference in Sarasota in 1979 we decided that it was time for another such meeting, to bring together as many as possible of the investigators interested in fish acoustics in order to assess the current state of our knowledge and predict directions for research for the next several years. Such a meeting appeared par ticularly timely, since over the past four or five years there have been many new studies that have provided new empirical and theoretical work on basic mechanisms of fish audition. Furthermore, it became evident, as we made up preliminary lists of possible participants, that few of the currently active workers were in the field back in 1966. In fact, of the current participants, only Drs."
For more than a century, we were restricted to studying evolution from the outside, observing its progress only through the fossil record. No longer. We can now also read the DNA record. As well as containing the operating instructions for everyday existence and for making the next generation, DNA contains a vast and detailed history of the three-billion-year development of life on Earth. It is a living chronicle of evolution, pinpointing the precise changes that have enabled Earth's marvelous creatures to inhabit the planet's shifting environments, from the freezing waters of the Antarctic to the lush canopy of the rainforest. Captivating and lucid, The Making of the Fittest delves deep into the DNA record to reveal not just how the fittest survive but also how they are made.
The cow. Central to human existence since time began, cows have served as a source of food, a means of labor, an economic resource, an inspiration for art, and even as a religious icon--many cultures worshipped the cow as a god. Beef is the captivating history of an animal whose relationship with humanity has shaped the world as we know it. Peppered with lively anecdotes and culinary tidbits, this engaging panoramic view of the cow's long and colorful history spans the globe--from ancient Mediterranean bullfighting rings to the rugged grazing grounds of eighteenth-century England, from the quiet farms of Japan's Kobe beef cows to crowded American stockyards and the remote villages in East Africa that are home to the Masai, to whom cattle mean everything. Leaving no stone unturned, Beef is not only a compelling story but a necessary call to arms, offering practical solutions for confronting the sad current condition of the wasteful and destructive beef and dairy industries. You will never look at steak the same way again.
There are many unanswered questions regarding the molecular nature of antibodies, components of complement, and other substances which participate in the immune response. The list of substances which need to be analyzed chemically is increasing. Plasma cell products, of course, have long been of great interest because the most prevalent ones are immunoglobulins. Other cell types, however, are the source of the broad spectrum of additional substances which classically fall into the sanctum of the molecular immunologist. It is these substances, and especially those more recently discovered, which are responsible for the broadening investigative interests of immunologists. In this volume we have provided you with descriptions of research being done with immunoglobulins and with complement. Additionally, we have in cluded two reports that deal with molecules which are among the more recent acquisitions of the molecular immunologist. The components of complement are known to react in a cascading manner which results in the lysis of cellular antigens. The first step in the classical pathway requires the activation of CI by the antibody-antigen aggregates. This volume of Contemporary Topics in Molecular Immunology begins with the report of Reid and Porter which describes their investigation of the mechanism of activation of C I. Their descriptions of C I q and of the reaction of C I with immunoglobulins are especially intriguing. It is clearly apparent from their report that activation of the components of complement is a complex phenome non.
From geometry in motion to the possibilities of pi, this stunning volume reveals how art inspired the beauty and poetry of mathematical principles. The worlds of visual art and mathematics come together in this spectacular volume by award-winning writer Stephen Ornes. He explores the growing sensation of math art, presenting more than 80 pieces, including a crocheted, colorful representation of non-Euclidian geometry that looks like sea coral and a 65-ton, 28-foot-tall bronze sculpture covered in a space-filling curve. For each work, we get the artist's story followed by accessible and thought-provoking explanations of the mathematical concept and equations behind the art. From 3D-printed objects that give real form to abstract mathematical theories, to mystic fractals, to Andy Warhol as a solution to the Traveling Salesman Problem, these artworks embody some of strangest, most beautiful relationships among numbers and across dimensions.
Mathematics scares and depresses most of us, but politicians, journalists and everyone in power use numbers all the time to bamboozle us. Most maths is really simple - as easy as 2+2 in fact. Better still it can be understood without any jargon, any formulas - and in fact not even many numbers. Most of it is commonsense, and by using a few really simple principles one can quickly see when maths, statistics and numbers are being abused to play tricks - or create policies - which can waste millions of pounds. It is liberating to understand when numbers are telling the truth or being used to lie, whether it is health scares, the costs of government policies, the supposed risks of certain activities or the real burden of taxes.
To scientists engaged in research on the cellular mechanisms in the mammalian brain, concepts of "motivation" seem to be a logical neces sity, even if they are not fashionable. Immersed in the detailed, time consuming research required to deal with mammalian nerve cells, we usually pay scant attention to the more global brain -behavior questions that have arisen from decades of biological and psychological studies. We felt it was time to confront these issues-namely, how far has neuro biological investigation come in uncovering mechanisms by which moti vational signals influence behavior? At Rockefeller University, we have recently held a course on this subject. We restricted our treatment to those motivational systems most tractable to physiological approaches, and invited scientists skilled in both behavioral issues and physiological techniques to participate. This volume results from that course. The deans and administration at Rockefeller University provided much help in planning the course, and the staff of Springer-Verlag assisted in planning the book. Gabriele Zummer helped organize both the course and the processing of book chapters. They all deserve our thanks. December 1981 Donald W.

With more than 50% of the world's population already living in towns and cities, migration from rural areas continuing at an alarming rate in developing countries and suburbanisation using more and more land in developed countries, the urban environment has become supremely important with regard to human health and wellbeing. For centuries, urbanisation has caused relatively low level soil conta- nation mainly by various wastes. However, from the time of the Industrial Revolution onwards, both the scale of urban development and the degree of soil contamination rapidly increased and involved an ever widening spectrum of c- taminants. With constraints on the supply of land for new urban development in many countries, it is becoming increasingly necessary to re-use previously dev- oped (brownfield) sites and to deal with their accompanying suites of contaminants. It is therefore essential to fully understand the diversity and properties of urban soils, to assess the possible risks from the contaminants they contain and devise ways of cleaning up sites and/or minimizing hazards. The author, Helmut Meuser, is Professor of Soil Protection and Soil Clean-up at the University of Applied Sciences, Osnabruck and is one of Europe's foremost experts on contamination from technogenic materials in urban soils. He has many years' experience of research in Berlin, Essen, Osnabruck, other regions of Germany, and several other countries.
Stephen Webb, author of WHERE IS EVERYBODY?, takes the interested amateur on a thrilling and enlightening tour of the amazing, even bizarre, new ideas of modern physics, including alternatives to the Big Bang, parallel universes, and an imaginary trip to the other side of the black hole.
Few scientists have made lasting contributions to as many fields as Francis Galton. He was an important African explorer, travel writer, and geographer. He was the meteorologist who discovered the anticyclone, a pioneer in using fingerprints to identify individuals, the inventor of regression and correlation analysis in statistics, and the founder of the eugenics movement. Now, Nicholas Gillham paints an engaging portrait of this Victorian polymath.
Every year, air pollution prematurely kills seven million people around the world, in rich countries and poor ones. It is strongly linked to strokes, heart attacks, many kinds of cancer, premature birth and dementia, among other ailments. In Choked, Beth Gardiner travels the world to meet the scientists who have transformed our understanding of pollution's effects on the human body, and to trace the economic forces and political decisions that have allowed it to remain at life-threatening levels. But she also focuses on real-world solutions, and on inspiring stories of people fighting for a healthier future. Compellingly written, and alive with the personalities of the people who study, breathe and fight bad air, Choked is a vital contribution on one of the most important - but too often ignored - issues of our time.
Even as the popularity of videogames has skyrocketed, a dark cloud continues to hang over them. Many people who play games feel embarrassed to admit as much, and many who don't worry about the long-term effects of a medium often portrayed as dangerous and corruptive. Drawing on years of experience working directly with people who play games, clinical psychologist Alexander Kriss steers the discourse away from extreme and factually inaccurate claims around the role of games in addiction, violence and mental illness, instead focusing on the importance of understanding the unique relationship that forms between a game and its player. Through vivid psychotherapy case illustrations, autobiographical memoir, and a wide range of psychological theory and research, The Gaming Mind lays out an honest and humanistic vision of games, their potentials and risks, and how they can teach us more about who we are and who we could be.
In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.
Katherine Teilmann Van Dusen and Sarnoff A. Mednick This introduction delineates what we consider to be three of the most important impediments to the advance of knowledge in the field of criminology. The most fundamental need is for more studies of the nature and progress of criminal and delinquent careers. The second need is for more prospective, longitudinal studies of the etiology of crime and delinquency. The third need concerns the lack of interdisciplinary research toward a more integrated understanding of delinquent and criminal behavior. Criminal and Delinquent Careers The birth cohort study by Wolfgang, Figlio and Sellin (1972) was heralded by many (Farrington, 1973; Erickson, 1973; Weis, 1974) as a landmark which allowed researchers to study the course of delinquency without the usual sampling biases that plagued other, cross-sectional research. For the first time, we could get a reasonable picture of when delinquency usually starts, what proportion of the population engages in delinquency, what types of delinquencies they engage in, what proportion continue, and so on. Cross sectional studies do not permit the investigation of careers because cross 1 PROSPECTIVE STUDIES OF CRIME AND DELINQUENCY 2 sectional sampling includes only portions of careers for many of the individuals sampled. This is just one of the many problems that restricted researchers' ability to study the nature of criminal careers.
More than 1200 diterpenes have been identified from approximately 550 Compo sitae taxa (Figure 1 [pp. 219-384], Tables 1-3 [pp. 7-218]). The annual output of such reports rose sharply during the past several years, a trend that was also reflected by other major lipophilic constituents of the Compositae: acetylenes (63, 465), sesquiterpene lactones (266, 458), and benzofurans and chromenes (429). Unlike these other natural products, no review of the diterpene chemistry of the Compositae has been published. Given the bulk of data currently on hand, a review of this topic is clearly overdue. Several major goals influenced the preparation of this review. The first was to provide a useful reference to guide terpenoid chemists to the literature of known compounds. The published reports for 1200 structures provide a sizable body of spectroscopic data applicable to the investigation of new compounds. The study of diterpenes has been hampered by the absence of an all-inclusive nomenclature and classification system for the various skeletal types. Conse quently, a second goal was to organize structural data into a classification scheme designed to group compounds by biogenetic homology, and to standardize such features as diterpene nomenclature and numbering. Pursuant to this goal, the published names (Table 1) and numbering systems (Table 2) for all compounds are included.

In this pioneering book Rupert Sheldrake shows how science helps validate seven practices on which all religions are built, and which are part of our common human heritage: * Meditation * Gratitude * Connecting with nature * Relating to plants * Rituals * Singing and chanting * Pilgrimage and holy places. The effects of spiritual practices are now being investigated scientifically as never before, and many studies have shown that religious and spiritual practices generally make people happier and healthier. Rupert Sheldrake summarizes the latest scientific research on what happens when we take part in these practices, and suggests ways that readers can explore these fields for themselves. For those who are religious, Science and Spiritual Practices will illuminate the evolutionary origins of their own traditions and give a new appreciation of their power. For the non-religious, this book will show how the core practices of spirituality are accessible to all, even if they do not subscribe to a religious belief system. This is a book for anyone who suspects that in the drive towards radical secularism, something valuable has been left behind. Rupert Sheldrake believes that by opening ourselves to the spiritual dimension we may find the strength to live more wholesome and fulfilling lives.
This book explains hyperspace and multidimensional geometries in an effort to help readers to manipulate, visualize, and think about the higher spatial dimensions that all serious physical theories since relativity have required. This book alternates sections explaining the science with a fictional story line that exemplifies, comments on, and helps to clarify the science. The book also features a number of appendices, including annotated guides to the literature and to relevant science fiction, further commentary on the mathematics of hyperspace, questions and puzzles, and source code for modeling hyperspace. The book has the goal to explain the science of hyperspace accurately, but it is light and playful in its approach.
Fibronectins comprise a class of high molecular weight glycoproteins present both in extracellular matrices and in soluble form in body fluids. Although they have been studied for about forty years, their real significance emerged only during the past decade. Intensive research has focused on their role in platelet function, cell migration, the cytoskeleton, reticuloendothelial function, and on alterations in fibronectin distribution during development and disease. Fibronectins have emerged as glycoproteins with a very interesting set of properties generally involving adhesion of cells to cells or to extracellular material. In more recent years, the complete sequences of several fibronectin molecules and their genes were determined, the relation between structure and function was understood and much has been learned about cell surface receptors for fibronectins and other adhesive ligands. Having been at the forefront of all these exciting developments, the author has synthesized the entire field and with all the latest information at hand for the first time given it a clear perspective.
Writing for the general reader, Daniel Nettle tackles the question of why madness exists. He shows that there is, as long suspected, a link between madness and creative genius. He thus argues that the traits that lie behind madness have evolved because they have psychological benefits as well as psychological costs. |
