The definitive resource for working with powerful crystals! Sparkling, luminous, and colorful, it is no wonder crystals have always been regarded as a source of power from ancient times to present day. But with the enormous number of crystals now on the market, it is difficult to choose exactly the right stone. In 101 Power Crystals, internationally renowned crystal expert Judy Hall brings together 101 crystals that are powerful across a wide spectrum of uses and suitable for all types of user. Not all crystals suit everyone, and the selection has been specially chosen to offer alternatives and new possibilities that may not have been thought of before. This complete collection includes high vibration crystals that experienced crystal practitioners will want to explore as well as those with earthier vibrations that are suited to beginners or those developing their sensitivities. It also features some rare and recently discovered crystals and stones that have not been included in any other volume, such as Aurora Quartz, Que Sera, Trigonic Quartz, and Preseli Bluestone. Each entry covers the history, mythology, and symbolism of the crystal in addition to its healing properties and environmental effects. There are crystals and stones for love, health, protection, abundance, and many other powers.

Tap into the infinite potential of crystals; experience tremendous growth and self-discovery, and open yourself to the resonating energies of crystal healing for a more fulfilling life. Find Your Power: Crystals explores the different types of crystal healing and provides practical guidance, creative visualisation, positive inner dialogue, as well as meditations and techniques for harnessing the unlimited power of crystals. This unique guide also explores the different types of natural psychic abilities and provides guidance for helping you to turn them into powerful life-changing skills. Delve into the power of crystals to enrich your wellbeing.

An exploration of the scientific, historical, and paranormal qualities of quartz crystals and ancient crystal skulls • Explores the use of crystals throughout history, including their role in Atlantis and in alien technology • Offers step-by-step instructions to successfully use crystals in scrying, meditation, and Enochian magic • Includes never-before-published scientific findings on the author’s crystal skull as well as other crystal skulls researched at the British Museum • Explains how the Space-Time Crystal Matrix connects the physical world with the spiritual and may be the communication technology of the future Known for his in-depth scientific work on the Shroud of Turin and the Great Pyramid of Giza, John DeSalvo, Ph.D., now sets his sights on quartz crystals and their mystical counterpart, crystal skulls. Exploring the use of crystals from Mesopotamia and ancient Egypt to present-day technology, including their use in ritual and ceremonial magic and their importance in ancient religious literature, he examines the many physical and chemical properties of quartz crystals and explains how their crystalline lattice structure is the key to their amazing abilities, both scientific and paranormal. Reviewing the many paranormal claims about crystal skulls, DeSalvo reveals the scientific findings on his own ancient crystal skull as well as research by the British Museum on other famous crystal skulls. His investigation also extends to the recent discovery in Tibet of a trove of Dropa discs--grooved stones allegedly recording an ancient alien visit to Earth. Highlighting the use of quartz crystals and crystal skulls for psychic and spiritual purposes, DeSalvo offers step-by-step instructions for their use in scrying, meditation, and Enochian magic, including communication with angels. Reviewing accounts of power crystals in Atlantis and their use in alien technology, he explains how crystals connect the physical world with the spiritual via a powerful communication network linking all crystals and their memories--the Space-Time Crystal Matrix, a spiritual technology lost to the ages but which may become the communication system of the future.

Electronic oscillators using an electromechanical device as a frequency reference are irreplaceable components of systems-on-chip for time-keeping, carrier frequency generation and digital clock generation. With their excellent frequency stability and very large quality factor Q, quartz crystal resonators have been the dominant solution for more than 70 years. But new possibilities are now offered by micro-electro-mechanical (MEM) resonators, that have a qualitatively identical equivalent electrical circuit. Low-Power Crystal and MEMS Oscillators concentrates on the analysis and design of the most important schemes of integrated oscillator circuits. It explains how these circuits can be optimized by best exploiting the very high Q of the resonator to achieve the minimum power consumption compatible with the requirements on frequency stability and phase noise. The author has 40 years of experience in designing very low-power, high-performance quartz oscillators for watches and other battery operated systems and has accumulated most of the material during this period. Some additional original material related to phase noise has been added. The explanations are mainly supported by analytical developments, whereas computer simulation is limited to numerical examples. The main part is dedicated to the most important Pierce circuit, with a full design procedure illustrated by examples. Symmetrical circuits that became popular for modern telecommunication systems are analyzed in a last chapter.
