Book Description
Understanding gemstones in a geological context Gemstones are colorful treasures of the Earth that have captivated humans for thousands of years. The physical and chemical characteristics of each type of gem provide insights into the geological processes that created them. Geology and Mineralogy of Gemstones is a textbook aimed at upper-level undergraduate and graduate students. It presents the basic mineralogical and geological knowledge needed to understand gemstones and examines the characteristics and geological origins of different types of gemstone. Volume highlights include: Concepts in mineralogy Structure and chemical composition of minerals Geological processes that lead to the formation and movement of gemstones Equipment and tools used to examine gemstones and their physical properties The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Book Description
Legendary healer Diane Stein shares her extensive knowledge of gemstones in this concise agate-to-zircon reference. Each listing includes the stone's common name, its corresponding color and chakra, and a concise resume of its healing properties. Stein suggests ways to use stones to support physical and psychic well-being, by simply carrying one in a hand or pocket, wearing it as jewelry, or engaging in more advanced practices like the "laying on of stones." She also presents a glossary of terms designed for beginning students of metaphysical healing practices, and teaches how to clear, dedicate, and maintain crystals to maximize their beneficial effects. A quick reference to 550 gemstones and crystals (including many that are new to the marketplace), and their special healing properties and most helpful applications. Includes diagrams of the Kundalini (physical) and Hara Line (emotional) chakra healing systems for simplified cross-referencing with the stones. Diane Stein's books have sold more than half a million copies and are available in six languages.

Book Description
This book is a must-have for anyone serious about rendering in real time. With the announcement of new ray tracing APIs and hardware to support them, developers can easily create real-time applications with ray tracing as a core component. As ray tracing on the GPU becomes faster, it will play a more central role in real-time rendering. Ray Tracing Gems provides key building blocks for developers of games, architectural applications, visualizations, and more. Experts in rendering share their knowledge by explaining everything from nitty-gritty techniques that will improve any ray tracer to mastery of the new capabilities of current and future hardware. What you'll learn: The latest ray tracing techniques for developing real-time applications in multiple domains Guidance, advice, and best practices for rendering applications with Microsoft DirectX Raytracing (DXR) How to implement high-performance graphics for interactive visualizations, games, simulations, and more Who this book is for:Developers who are looking to leverage the latest APIs and GPU technology for real-time rendering and ray tracing Students looking to learn about best practices in these areas Enthusiasts who want to understand and experiment with their new GPUs
