Quintessence Element

Understanding Physics

Understanding Physics provides a thorough grounding in contemporary physics while placing physics into its social and historical context. Based in large part on the highly respected Project Physics Course developed by two of the authors, it also integrates the results of recent pedagogical research. The text thus: - teaches about the basic phenomena in the physical world and the concepts developed to explain them - shows that science is a rational human endeavor with a long and continuing tradition, involving many different cultures and people - develops facility in critical thinking, reasoned argumentation, evaluation of evidence, mathematical modeling, and ethical values The treatment emphasizes not only what we know but also how we know it, why we believe it, and what effects that knowledge has: - Why do we believe the Earth and planets revolve around the Sun? - Why do we believe that matter is made of atoms? - How do relativity theory and quantum mechanics alter our conception of Nature and in what ways do they leave the classical concepts unchanged? - What impact does the knowledge of finite energy resources have on our society? - How have applications of fundamental science (such as the steam engine, the laser, the electric generator, the transistor) affected our lives? - How does the evidence for non-scientific ideas, such as UFOs, ESP, and the like, differ from the evidence for accepted scientific results?

Four Elements of the Wise

An in-depth exploration of the elements, their lore, history, correspondences, and use in spellwork and ritual. The four elements are the pillars that uphold the manifest world and anchor spirit to matter. They are associated with a wide range of spiritual entities, from small elementals to divine beings. This book explores the consciousness of the elements, which provides a system of understanding that supports most of the magic of the West and paganism. The use of the elements in a wide range of systems and practices will be examined. Much has been written about the four elements already; this book offers new teachings for newcomers and long-time practitioners alike. Each of the four elements is explored in depth, including how they interact and change as they rise on the planes. Practical applications for working with the elements are also woven throughout the book. The book concludes with the union of the elements that is more than just becoming Spirit, but the completion of their Great Work.
