Earth, air, fire and water are the four elements worshiped in many indigenous cultures and celebrated in earth–based spiritualities such as Wicca. In The Earth Path, America's best–known witch offers readers a primer on how to open our eyes to the world around us, respect nature's delicate balance, and draw upon its tremendous powers.Filled with inspiring meditations, chants, and blessings, it offers healing for the spirit in a stressed world and helps readers find their own sources of strength and renewal.Will appeal to Starhawk's traditional Pagan, New Age, and feminist readership.Young women newly interested in magic and witchcraft.A new and growing generation of those involved in ecology

    This is the original book compilation of Foxfire material which introduces Aunt Arie and her contemporaries and includes log cabin building, hog dressing, snake lore, mountain crafts and food, and "other affairs of plain living."

    Never again will you order the Poisson Distribution in a French restaurant!This updated version features all new material.

    These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

    We dive down to see coral reefs, not realizing that an ingredient in our sunscreen feeds a virus that kills the reef. We wear organic cotton t-shirts, but don’t know that its dyes may put factory workers at risk for leukemia. In Ecological Intelligence, Daniel Goleman reveals why so many of the products that are labeled green are a “mirage,” and illuminates our wild inconsistencies in response to the ecological crisis.Drawing on cutting-edge research, Goleman explains why we as shoppers are in the dark over the hidden impacts of the goods and services we make and consume, victims of a blackout of information about the detrimental effects of producing, shipping, packaging, distributing, and discarding the goods we buy.But the balance of power is about to shift from seller to buyer, as a new generation of technologies informs us of the ecological facts about products at the point of purchase. This “radical transparency” will enable consumers to make smarter purchasing decisions, and will drive companies to rethink and reform their businesses, ushering in, Goleman claims, a new age of competitive advantage.

    Working with imaginative and often hilarious computer simulations, he analyzes the roots of catastrophe, showing city planners in the very act of creating gridlock and disaster, or public health authorities setting the scene for starvation. The Logic of Failure is a compass for intelligent planning and decision-making that can sharpen the skills of managers, policymakers and everyone involved in the daily challenge of getting from point A to point B.

    It proposes enlightening similarities between, for instance, maneuvering in limited war and in a traffic jam; deterring the Russians and one's own children; the modern strategy of terror and the ancient institution of hostages.

    This concept is at the root of the computational worldview, which basically says that very complex systems — the world we live in — have their beginnings in simple mathematical equations. We've lately come to understand that such an algorithm is only the start of a never-ending story — the real action occurs in the unfolding consequences of the rules. The chip-in-a-box computers so popular in our time have acted as a kind of microscope, letting us see into the secret machinery of the world. In Lifebox, Rucker uses whimsical drawings, fables, and humor to demonstrate that everything is a computation — that thoughts, computations, and physical processes are all the same. Rucker discusses the linguistic and computational advances that make this kind of "digital philosophy" possible, and explains how, like every great new principle, the computational world view contains the seeds of a next step.

    Haraway offers provocative new ways to reconfigure our relations to the earth and all its inhabitants. She eschews referring to our current epoch as the Anthropocene, preferring to conceptualize it as what she calls the Chthulucene, as it more aptly and fully describes our epoch as one in which the human and nonhuman are inextricably linked in tentacular practices. The Chthulucene, Haraway explains, requires sym-poiesis, or making-with, rather than auto-poiesis, or self-making. Learning to stay with the trouble of living and dying together on a damaged earth will prove more conducive to the kind of thinking that would provide the means to building more livable futures. Theoretically and methodologically driven by the signifier SF—string figures, science fact, science fiction, speculative feminism, speculative fabulation, so far—Staying with the Trouble further cements Haraway's reputation as one of the most daring and original thinkers of our time.

    

    Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    In 1838, John ames Audubon’s Birds of America was one...In 1934, Roger Tory Peterson produced Field Guide to the Birds...Now comes The Sibley Guide to Birds.”Thus did The New York Times, in 1999, greet David Allen Sibley’s monumental book, which has quickly been established nationwide as the peerless, standard bird identification guide. The Sibley Guide to Bird Life and Behavior is the new landmark book from David Allen Sibley. Designed to enhance the birding experience and to enrich the popular study of North American birds, the book combines more than 795 of his full-color illustrations with authoritative text by 48 expert birders and biologists. In this new guide Sibley takes us beyond identification, to show us how birds live and what they do. Introductory essays outline the principles of avian evolution, life cycle, body structure, flight dynamics, and more. The 80 family-by-family chapters describe the amazing range of behavior dictated by birds’ biology and environment. Among the subjects covered and illustrated are:--molts and plumages--habitats--food and foraging--vocalizations and displays--courtship and breeding--rearing of young--migration and movements--scientific groupings--introduced species--accidental species --anatomy--flight patterns --nests and eggs--conservation--global distributionAccessibly written, superbly designed and organized, and brilliantly illustrated, The Sibley Guide to Bird Life and Behavior is an indispensable source of information on the avian life around us.

    Corporatism and globalization are two of the obvious villains here, but what part does human nature play in the problem? Since its inception in 1982, Orion magazine has been a forum for looking beyond the effects of ecological crises to their root causes in human culture. Less an anthology than a vision statement, this timely collection challenges the division of human society from the natural world that has often characterized traditional environmentalism. Edited and introduced by Barry Lopez, The Future of Nature encompasses such topics as local economies, the social dynamics of activism, America’s incarceration society, naturalism in higher education, developing nations, spiritual ecology, the military-industrial landscape, and the persistent tyranny of wilderness designation. Featuring the fine writing and insights for which Orion is famous, this book is required reading for anyone interested in a livable future for the planet.

    Without his groundbreaking work in relativity and quantum physics, our knowledge of the cosmos might lag decades behind where it is today. But Einstein was not only an extraordinary scientific thinker. He was a humanitarian who detested war and tried to stem the proliferation of hitherto unimaginably destructive weapons that his work had in part made possible. He spent a lifetime fighting authoritarianism and promoting personal freedom, selflessly standing up to those who posed a threat to those ideals.He was also a bona fide superstar and was instantly recognizable to millions who had not the least understanding of the intricacies of his scientific theories. Even now, the image of the tussled-hair 'mad professor' poking his tongue out at the camera is familiar across the globe. In How to Think Like Einstein, you can explore his unique approach to solving the great scientific mysteries of his age and trace the disparate ideas and influences that helped shape his personality and outlook - for better and worse.

    Whether William Bryant Logan is traversing the far reaches of the cosmos or plowing through our planet’s crust, his delightful, elegant, and surprisingly soulful meditations greatly enrich our concept of "dirt," that substance from which we all arise and to which we all must return.
