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.

Imagine the North American Indians as astronomers carefully watching the heavens, charting the sun through the seasons, or counting the sunrises between successive lumar phases. Then imagine them establishing observational sites and codified systems to pass their knowledge down through the centuries and continually refine it. A few years ago such images would have been abruptly dismissed. Today we are wiser. Living the Sky describes the exciting archaeoastronomical discoveries in the United States in recent decades. Using history, science, and direct observation, Ray A. Williamson transports the reader into the sky world of the Indians. We visit the Bighorn Medicine Wheel, sit with a Zuni sun priest on the winter solstice, join explorers at the rites of the Hopis and the Navajos, and trek to Chaco Canyon to make direct on-site observations of celestial events.

Trapped in an unbelievably strange world, Kia and Ryushi must struggle to understand their family's secret past, carve out a future for themselves, and escape to their own land.
