This volume examines mirrors and mirroring through a series of multidisciplinary essays, especially focusing on the intersection between technological and cultural dynamics of mirrors. The international scholars brought together here explore critical questions around the mirror as artefact and the phenomenon of mirroring. Beside the common visual registration of an action or inaction, in a two dimensional and reversed form, various types of mirrors often possess special abilities which can produce a distorted picture of reality, serving in this way illusion and falsehood. Part I looks at a selection of theory from ancient writers, demonstrating the concern to explore these same questions in antiquity. Part II considers the role reflections can play in forming ideas of gender and identity. Beyond the everyday, we see in Part III how oracular mirrors and magical mirrors reveal the invisible divine – prosthetics that allow us to look where the eye cannot reach. Finally, Part IV considers mirrors' roles in displaying the visible and invisible in antiquity and since.

Another Earth meets Perks of Being a Wallflower in this thoughtful, mesemerizing debut and subject of a TedX talk about the discovery of a mirror planet to Earth and how it dramatically changes the course of one Indian-American girl's junior year. “[O]ne of the most powerful reads of the year. A novel about family, race, and discovering who you are, Mirror in the Sky promises a unique read that blends YA contemporary struggles with imaginative science fiction." —Paste Magazine For Tara Krishnan, navigating Brierly, the academically rigorous prep school she attends on scholarship, feels overwhelming and impossible. Her junior year begins in the wake of a startling discovery: A message from an alternate Earth, light years away, is intercepted by NASA. This means that on another planet, there is another version of Tara, a Tara who could be living better, burning brighter, because of tiny differences in her choices. The world lights up with the knowledge of Terra Nova, the mirror planet, and Tara’s life on Earth begins to change. At first, small shifts happen, like attention from Nick Osterman, the most popular guy at Brierly, and her mother playing hooky from work to watch the news all day. But eventually those small shifts swell, the discovery of Terra Nova like a black hole, bending all the light around it. As a new era of scientific history dawns and Tara's life at Brierly continues its orbit, only one thing is clear: Nothing on Earth--or for Tara--will ever be the same again.

This open access book serves as textbook on the physics of the radiation belts surrounding the Earth. Discovered in 1958 the famous Van Allen Radiation belts were among the first scientific discoveries of the Space Age. Throughout the following decades the belts have been under intensive investigation motivated by the risks of radiation hazards they expose to electronics and humans on spacecraft in the Earth’s inner magnetosphere. This textbook teaches the field from basic theory of particles and plasmas to observations which culminated in the highly successful Van Allen Probes Mission of NASA in 2012-2019. Using numerous data examples the authors explain the relevant concepts and theoretical background of the extremely complex radiation belt region, with the emphasis on giving a comprehensive and coherent understanding of physical processes affecting the dynamics of the belts. The target audience are doctoral students and young researchers who wish to learn about the physical processes underlying the acceleration, transport and loss of the radiation belt particles in the perspective of the state-of-the-art observations.

Most scientists agree that Earth is warming rapidly. Glaciers are melting and rising seawaters are submerging islands and coastal cities. In the coming decades, millions will likely have to escape extreme weather caused by climate change. Some scientists say we need to act faster and with radical new technologies—now—to save our planet. They propose geoengineering, or "engineering Earth," to reset our global thermostat. Ideas include thickening clouds with chemicals to reduce the amount of sunlight and pulling carbon dioxide from the air with machines. However, critics say that geoengineering could backfire and create even worse weather. Is geoengineering too risky? Or is it our best hope of survival?

Explores the science of natural events and what turns them into disasters for human populations Natural hazards are present in every part of planet Earth. Sometimes a natural event – such as extreme weather, a volcanic eruption, earthquake or disease outbreak – turns into a disaster for humans, the environment, and the economy. Earth’s Natural Hazards and Disasters is a textbook for undergraduates that challenges students to think critically about disasters. It explains the science behind natural events and explores how to understand risk and prepare for disasters. Volume highlights include: Covers hazards in the geosphere, hydrosphere, atmosphere, and biosphere Explains the science of hazards in accessible terms Detailed case studies of specific disasters for each type of natural event Explores data-based risk mitigation strategies Discusses the roles of scientists, public officials, and the general public in hazard management Learning objectives and questions for discussion in each chapter 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.

A nature therapy session for the soul--encounter the benevolence of the living world through 12 essays on the Earth-healing powers of self-compassion and empathy. When healing is needed at the deepest level, nature will always call us back home--not only to the oak woods or water-filled coves, but to the homes within ourselves. In a series of 12 lyrical nature essays, herbalist, writer, and Earth intuitive Asia Suler illuminates the healing power of the living Earth--and gives us permission to nurture self-compassion and empathy as forces for personal and ecological healing. In a time of unprecedented ecological devastation, it’s easy to feel hopeless and disconnected. It’s easier still to mask our inherent goodness--to imagine that our unique and precious gifts simply aren’t enough, or forget the power of our inborn empathy. For those of us who are highly sensitive, innately attuned to the workings and whispers of the natural world, it can be hard to embody the belief that we’re enough as we are--and that can heal the Earth. Here, Suler reveals the opposite: our goodness, our empathy, our intuitive connections, and our capacity for self-compassion are more than personal traits or antidotes to despair: they are, in fact, our most potent vehicles for planetary transformation. And as we learn to more deeply nurture and accept ourselves, we unlock living, healing connections to Earth. Combining poetic nature writing with exercises and reflection prompts at the end of each essay, Mirrors in the Earth coaxes us to come as we are: to discover and tend the inherent brilliance and medicine that lives in each of us. From the manatee-calm springs of wild Florida to the flower-dotted coves of the world’s most biodiverse mountains, Mirrors in the Earth is an invitation and encounter with the benevolence of the living world--and a nature therapy session for the soul.
