From the observations of Ptolemy and Kepler to the Harmony of the Spheres and the hidden structure of the solar system, John Martineau reveals the exquisite orbital patterns of the planets and the mathematical relationships that govern them. A table shows the relative measurements of each planet in eighteen categories, and three pages show the beautiful dance patterns of thirty six pairs of planets and moons.

    In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events. Greek philosophers discovered eclipses' cause and used them to measure their world and the cosmos beyond. Victorian-era scientists mounted eclipse expeditions during the age of globe-spanning empires. And modern-day physicists continue to use eclipses to confirm Einstein's theory of relativity.Beautifully illustrated and lyrically written, Sun Moon Earth is the ideal guide for all eclipse watchers and star gazers alike.

    You'll learn how each Moon phase affects your spellwork, including the seldom-discussed energies of the true Blue Moon, the Black Moon, the void-of-course moon, and the lunar eclipse. Follow the Moon as she traverses each sign of the zodiac, and discover how each astrological phase affects magic, mundane events, and gardening--and how your personal Moon sign affects your magical work. This guide by popular author Dorothy Morrison includes more than 140 spells, chants, and rituals, along with Esbat celebrations for the Full Moon.

    Large format diagrams show these objects exactly as they appear in a small telescope and for each object there is information on the current state of our astronomical knowledge. Revised and updated, this new edition contains a chapter with ten new spreads describing spectacular deep sky objects visible from the southern hemisphere, and tips on observing the upcoming transits of Venus. It also discusses Dobsonian telescopes, with hints on using personal computers and the Internet as aids for planning an observing session. Also new to this edition are redrawn Guidepost figures at the beginning of each season chapter that allow readers to visualize a three-dimensional view of the sky's dome; redesigned seasonal object layouts that provide more space for the naked-eye charts; a new spread on double stars near Bo�tes has been added to Spring, replacing the Shrinking Double spread; and a unique When and Where to Look table has been added to the last page, among other new features. Unlike many guides to the night sky, this book is specifically written for observers using small telescopes. Clear and easy to use, this fascinating book will appeal to skywatchers of all ages and backgrounds. No previous knowledge of astronomy is needed.

    Maggie Aderin-Pocock. In fact, she earned her nickname “Lunatic” because of her deep fascination for all things lunar. In her lucidly written, comprehensive guide to the moon, Aderin-Pocock takes readers on a journey to our closest celestial neighbor, exploring folklore, facts, and future plans.         She begins with the basics, unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She travels back in time to track humanity’s relationship with the moon — beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years — and then to the future, analyzing the pros and cons of continued space travel and exploration. Throughout the book are sidebars, graphs, and charts to enhance the facts as well as black-and-white illustrations of the moon and stars. The Book of the Moon will be published for the 50th anniversary of the moon landing.

    Jim Carter, the Einstein of outsiders, has developed his own complete theory of matter and energy and gravity that he demonstrates with experiments in his backyard,-with garbage cans and a disco fog machine he makes smoke rings to test his ideas about atoms. Captivated by the imaginative power of his theories and his resolutely DIY attitude, Wertheim has been following Carter's progress for the past decade.Centuries ago, natural philosophers puzzled out the laws of nature using the tools of observation and experimentation. Today, theoretical physics has become mathematically inscrutable, accessible only to an elite few. In rejecting this abstraction, outsider theorists insist that nature speaks a language we can all understand. Through a profoundly human profile of Jim Carter, Wertheim's exploration of the bizarre world of fringe physics challenges our conception of what science is, how it works, and who it is for.

    S. Lewis's famed but apparently disorganised Chronicles of Narnia have an underlying symbolic coherence, pointing to such possible unifying themes as the seven sacraments, the seven deadly sins, and the seven books of Spenser's Faerie Queene. None of these explanations has won general acceptance and the structure of Narnia's symbolism has remained a mystery.Michael Ward has finally solved the enigma. In Planet Narnia he demonstrates that medieval cosmology, a subject which fascinated Lewis throughout his life, provides the imaginative key to the seven novels. Drawing on the whole range of Lewis's writings (including previously unpublished drafts of the Chronicles), Ward reveals how the Narnia stories were designed to express the characteristics of the seven medieval planets - - Jupiter, Mars, Sol, Luna, Mercury, Venus, and Saturn - - planets which Lewis described as "spiritual symbols of permanent value" and "especially worthwhile in our own generation." Using these seven symbols, Lewis secretly constructed the Chronicles so that in each book the plot-line, the ornamental details, and, most important, the portrayal of the Christ-figure of Aslan, all serve to communicate the governing planetary personality. The cosmological theme of each Chronicle is what Lewis called 'the kappa element in romance', the atmospheric essence of a story, everywhere present but nowhere explicit. The reader inhabits this atmosphere and thus imaginatively gains connaitre knowledge of the spiritual character which the tale was created to embody.Planet Narnia is a ground-breaking study that will provoke a major revaluation not only of the Chronicles, but of Lewis's whole literary and theological outlook. Ward uncovers a much subtler writer and thinker than has previously been recognized, whose central interests were hiddenness, immanence, and knowledge by acquaintance."
