Bestselling author and crystal expert Philip Permutt offers the essential guide on how to take advantage of the powerful properties of crystals and how to apply their healing energies. Crystals not only heal but also affect how we feel and influence our responses to the wider world. They can support us when we feel down and help to boost our natural abilities when we're doing well or need a helping hand. Crystals improve the quality of our lives. If simply by adding beauty, they make us feel better. Crystal Connections is a detailed, accessible and fully illustrated guide to harnessing the magic of crystals, written by one of the world's leading crystal healers. While there are many books on crystals, this one is directed at communicating and understanding the messages within them. Learn how to recognise and connect with the energy of your crystals, work with them in dowsing, divination and healing practices, how they relate to chakras, how to cleanse and look after them and much more. Also included is a full-colour crystal finder section featuring 101 of the most common crystals.

A beautiful full-color guide to 250 healing crystals Crystals have been used for millennia for physical and psychic healing, and this book shows you how to harness their energy and power in your everyday life. With a simple, easy-to-understand description and a full-color photo for each crystal, Laurelle Rethke's Connecting with Crystals is a handy reference and a beautiful object for anyone interested in the ancient art of crystal healing.

Analyzes the structure of crystals and describes techniques for using them in holistic healing, stress management, and telepathic communication.

New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.
