Profiles the lives and work of eight visionaries who dedicated their lives to critical environmental issues.

A Note from the Author: On August 24, 2006, at the 26th General Assembly of the International Astronomical Union (IAU) in Prague, by a majority vote of only the 424 members present, the IAU (an organization of over 10,000 members) passed a resolution defining planet in such a way as to exclude Pluto and established a new class of objects in the solar system to be called "dwarf planets," which was deliberately designed to include Pluto. With the discovery of Eris (2003 UB313)—an outer solar system object thought to be both slightly larger than Pluto and twice as far from the Sun—astronomers have again been thrown into an age-old debate about what is and what is not a planet. One of many sizeable hunks of rock and ice in the Kuiper Belt, Eris has resisted easy classification and inspired much controversy over the definition of planethood. But, Pluto itself has been subject to controversy since its discovery in 1930, and questions over its status linger. Is it a planet? What exactly is a planet? Is Pluto a Planet? tells the story of how the meaning of the word "planet" has changed from antiquity to the present day, as new objects in our solar system have been discovered. In lively, thoroughly accessible prose, David Weintraub provides the historical, philosophical, and astronomical background that allows us to decide for ourselves whether Pluto is indeed a planet. The number of possible planets has ranged widely over the centuries, from five to seventeen. This book makes sense of it all—from the ancient Greeks' observation that some stars wander while others don't; to Copernicus, who made Earth a planet but rejected the Sun and the Moon; to the discoveries of comets, Uranus, Ceres, the asteroid belt, Neptune, Pluto, centaurs, the Kuiper Belt and Eris, and extrasolar planets. Weaving the history of our thinking about planets and cosmology into a single, remarkable story, Is Pluto a Planet? is for all those who seek a fuller understanding of the science surrounding both Pluto and the provocative recent discoveries in our outer solar system.

There are more crows now than ever. Their abundance is both an indicator of ecological imbalance and a generous opportunity to connect with the animal world. Crow Planet reminds us that we do not need to head to faraway places to encounter "nature." Rather, even in the suburbs and cities where we live we are surrounded by wild life such as crows, and through observing them we can enhance our appreciation of the world's natural order. Crow Planet richly weaves Haupt's own "crow stories" as well as scientific and scholarly research and the history and mythology of crows, culminating in a book that is sure to make readers see the world around them in a very different way.

Planets in Play is the first foundational book that lets the reader reimagine his or her inner life through the self-exploratory language of astrology. Author Laurence Hillman-a widely respected astrologer with a loyal following and a formidable online presence-reconnects the planets with the character traits given them by the ancients. Whether one accepts astrology as being "real," its language and concepts can go a long way toward helping us see the archetypes that play on our lives. In observing the strengths, weaknesses, and character traits of each planet and zodiac sign, readers will receive a toolbox filled with instruments with which to newly understand their lives. The reader will then be able to make more conscious choices about how he or she is living out these different aspects. To that end, Hillman provides specific tactics and highly practical ideas of how to expressly nourish or minimize these tendencies through choice of behavior, lifestyle, and personal surroundings. Case examples, stories, and anecdotes run throughout the book to demonstrate and ease this process. In its appendices, Planets in Play provides a guide in how to get a quality astrological reading, with an emphasis on one's dominant archetypes. In addition, Hillman offers a basic grounding in astrology for those readers, therapists, or counselors who wish to learn how the ancient art works at a psychological level without necessarily committing themselves to its study.

Looks at the orbital patterns of the planets and the mathematical patterns surrounding them.

When the ancient Greeks looked up into the heavens, they saw not just sun and moon, stars and planets, but a complete, coherent universe, a model of the Good that could serve as a guide to a better life. How this view of the world came to be, and how we lost it (or turned away from it) on the way to becoming modern, make for a fascinating story, told in a highly accessible manner by Rémi Brague in this wide-ranging cultural history. Before the Greeks, people thought human action was required to maintain the order of the universe and so conducted rituals and sacrifices to renew and restore it. But beginning with the Hellenic Age, the universe came to be seen as existing quite apart from human action and possessing, therefore, a kind of wisdom that humanity did not. Wearing his remarkable erudition lightly, Brague traces the many ways this universal wisdom has been interpreted over the centuries, from the time of ancient Egypt to the modern era. Socratic and Muslim philosophers, Christian theologians and Jewish Kabbalists all believed that questions about the workings of the world and the meaning of life were closely intertwined and that an understanding of cosmology was crucial to making sense of human ethics. Exploring the fate of this concept in the modern day, Brague shows how modernity stripped the universe of its sacred and philosophical wisdom, transforming it into an ethically indifferent entity that no longer serves as a model for human morality. Encyclopedic and yet intimate, The Wisdom of the World offers the best sort of history: broad, learned, and completely compelling. Brague opens a window onto systems of thought radically different from our own.
