Humanity will finally be saved or destroyed in the shattering conclusion to the post-apocalyptic and highly acclaimed NYT bestselling trilogy that won the Hugo Award three years in a row. The Moon will soon return. Whether this heralds the destruction of humankind or something worse will depend on two women. Essun has inherited the power of Alabaster Tenring. With it, she hopes to find her daughter Nassun and forge a world in which every orogene child can grow up safe. For Nassun, her mother's mastery of the Obelisk Gate comes too late. She has seen the evil of the world, and accepted what her mother will not admit: that sometimes what is corrupt cannot be cleansed, only destroyed.

This volume outlines the fundamentals and applications of light scattering, absorption and polarization processes involving ice crystals.

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.

Step into a world of photography that most artists consider magical. The closer you get to things, the more fascinating they become. Unimaginable details can be captured with the aid of special photography techniques and equipment, detailed at length within these pages. Macro photographers play by a different rulebook. The challenges faced from the subject matter, the equipment and even the laws of physics make this an ambitious genre of photography. It can be abstract, it can tell stories, and it can spark your imagination. Author and “Mad Scientist” photographer Don Komarechka covers every area of macro photography, from simple beginnings and tips to help you get the most out of your first macro lens, all the way through a masterclass in the obscure. Topics include: - Redefining the rules of composition - Finding and exploring narratives we ignore - The challenges of magnification - Camera equipment choices and recommendations - Inexpensive ways to get “closer” - Controlling and sculpting light - Overcoming shallow focus - Using water droplets as lenses for enchanted refractions - The art of photographic discovery: “what if?” - Winter macro: snowflakes and freezing soap bubbles - Ultraviolet fluorescence macro - Stereoscopic 3D macro photography - MANY more topics down the rabbit hole

This book traces the journeys of a stone across the world. From its remote point of origin in the city of Nishapur in eastern Iran, turquoise was traded through India, Central Asia, and the Near East, becoming an object of imperial exchange between the Safavid, Mughal, and Ottoman empires. Along this trail unfolds the story of turquoise--a phosphate of aluminum and copper formed in rocks below the surface of the earth--and its discovery and export as a global commodity. In the material culture and imperial regalia of early modern Islamic tributary empires moving from the steppe to the sown, turquoise was a sacred stone and a potent symbol of power projected in vivid color displays. From the empires of Islamic Eurasia, the turquoise trade reached Europe, where the stone was collected as an exotic object from the East. The Eurasian trade lasted into the nineteenth century, when the oldest mines in Iran collapsed and lost Aztec mines in the Americas reopened, unearthing more accessible sources of the stone to rival the Persian blue. Sky Blue Stone recounts the origins, trade, and circulation of a natural object in the context of the history of Islamic Eurasia and global encounters between empire and nature.

A beautiful crystal color directory and crystal gallery profile over one hundred of these extraordinary works of nature. Detailed information on the effect each crystal has on mind, body, and spirit is combined with practical advice on crystal healing

Based on an exhibition organized by Joachim Pissarro and curator of contemporary art at Crystal Bridges Museum of American Art, Lauren Haynes, Crystals in Art: Ancient to Today explores the complex and varied connections between crystal and art throughout the world. Included are both ancient artifacts—such as engraved gems, figurines, and vases—and works from contemporary artists around the world that explore the power of crystal in art by drawing on its form, properties, and mysterious qualities. Featuring more than sixty-five works from ancient Egypt and Greece, through to Rome, China, India, Japan, the Middle East, the Americas, and beyond, this book invites readers to discover how the power of crystal transcends the boundaries of time and space. Taken together, all of these objects illustrate how crystal has bridged the gap between things we can see and things we can’t: science and art, fact and faith, medicine and magic—the visible and the invisible. Published in collaboration with Crystal Bridges Museum of American Art and University of Arkansas School of Art.
