"A treasure trove of practical magic for both novices and more experienced practitioners...beautifully crafted spells that invoke the alchemy of possibility."—PanGaia A leaf from an oak tree...a wildflower...water from a sparkling stream...dirt from a cool dark cave—these are the age-old tools of natural magic. Born of the earth, possessing inherent power, they await only our touch and intention to bring their magical qualities to life. The four elements are powerful magical tools. Using their energies, we can transform ourselves, our lives, and our world. This much-loved, classic guide offers more than seventy-five spells, rites, and simple rituals you can perform using the marvelous powers of the natural world. Scott Cunningham was a greatly respected teacher and one of the most influential members of the modern Craft movement. A practitioner of elemental magic for twenty years, he wrote more than fifty books, including the seminal Wicca: A Guide for the Solitary Practitioner.

Bachelard called them "the hormones of the imagination." Hegel observed that, "through the four elements we have the elevation of sensuous ideas into thought." Earth, air, fire, and water are explored as both philosophical ideas and environmental issues associated with their classical and perennial conceptions. David Macauley embarks upon a wide-ranging discussion of their initial appearance in ancient Greek thought as mythic forces or scientific principles to their recent reemergence within contemporary continental philosophy as a means for understanding landscape and language, poetry and place, the body and the body politic. In so doing, he shows the importance of elemental thinking for comprehending and responding to ecological problems. In tracing changing views of the four elements through the history of ideas, Macauley generates a new vocabulary for and a fresh vision of the environment while engaging the elemental world directly with reflections on their various manifestations.

With pages of spectacular photographs, this book pays homage to the powerful forces that shape our planet--fire, ice, water, and wind--revealing extraordinary landscapes and breathtaking geological features. These images, of geysers spewing scalding water, glaciers chiseling out the mountainsides, and red-hot molten lava exploding, demonstrate how Earth's appearance resulted from the incessant, powerful activity of nature and climate change. The portrait that emerges from this exceptional journey captures a living, endlessly changing, world.

In "Earth Under Fire, " Paul LaViolette investigates the connection between ancient world catastrophe myths and modern scientific evidence of a galactic destruction cycle, demonstrating how past civilizations accurately recorded the causes of these cataclysmic events, knowledge of which may be crucial for the human race to survive the next catastrophic superwave cycle.

On Generation and Corruption Aristotle - On Generation and Corruption, also known as On Coming to Be and Passing Away is a treatise by Aristotle. Like many of his texts, it is both scientific and philosophic (although not necessarily scientific in the modern sense). The philosophy, though, is essentially empirical; as in all Aristotle's works, the deductions made about the unexperienced and unobservable are based on observations and real experiences.

A provocative rethinking of how humans and fire have evolved together over time—and our responsibility to reorient this relationship before it's too late.​ The Pyrocene tells the story of what happened when a fire-wielding species, humanity, met an especially fire-receptive time in Earth's history. Since terrestrial life first appeared, flames have flourished. Over the past two million years, however, one genus gained the ability to manipulate fire, swiftly remaking both itself and eventually the world. We developed small guts and big heads by cooking food; we climbed the food chain by cooking landscapes; and now we have become a geologic force by cooking the planet. Some fire uses have been direct: fire applied to convert living landscapes into hunting grounds, forage fields, farms, and pastures. Others have been indirect, through pyrotechnologies that expanded humanity's reach beyond flame's grasp. Still, preindustrial and Indigenous societies largely operated within broad ecological constraints that determined how, and when, living landscapes could be burned. These ancient relationships between humans and fire broke down when people began to burn fossil biomass—lithic landscapes—and humanity's firepower became unbounded. Fire-catalyzed climate change globalized the impacts into a new geologic epoch. The Pleistocene yielded to the Pyrocene. Around fires, across millennia, we have told stories that explained the world and negotiated our place within it. The Pyrocene continues that tradition, describing how we have remade the Earth and how we might recover our responsibilities as keepers of the planetary flame.

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

SHORTLISTED FOR THE ROYAL SOCIETY SCIENCE PRIZE 2022 'A joyful collision of science, history and nature writing' Helen Gordon, author of Notes from Deep Time Adam Sedgwick was a priest and scholar. Roderick Murchison was a retired soldier. Charles Lapworth was a schoolteacher. It was their personal and intellectual rivalry, pursued on treks through Wales, Scotland, Cornwall, Devon and parts of western Russia, that revealed the narrative structure of the Paleozoic Era, the 300-million-year period during which life on Earth became recognisably itself. Nick Davidson follows in their footsteps and draws on maps, diaries, letters, field notes and contemporary accounts to bring the ideas and characters alive. But this is more than a history of geology. As we travel through some of the most spectacular scenery in Britain, it's a celebration of the sheer visceral pleasure generations of geologists have found, and continue to find, in noticing the earth beneath our feet.
