A visual exploration of the power and behavior of light, across the electromagnetic spectrum, and how it affects life on earth and everything in the Universe. Light allows us to see everything around us, but humans can only see a sliver of all light, known as the electromagnetic spectrum. Here, Kim Arcand and Megan Watzke present the subject of light as never before. Organized along the order of the electromagnetic spectrum, each chapter focuses on a different type of light. From radio waves, harnessed for telecommunications, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. An introductory chapter describes what light is and how it behaves, while hundreds of full-color photographs and illustrations demonstrate concepts and make for a stunning book that's a joy to read and browse.

Building Physics: Lighting, Seeing in the Artificial Environment deals with basic principles of lighting as used in architecture, in building maintenance, and in an artificial environment. The book starts with the process of how humans see; the interaction of the eye and mind; and the effects of fatigue, visual disorders, and age. The phenomena of light are then discussed — how light behaves and how it is measured. Light and light waves beyond the visible spectrum are explained scientifically as being part of the electromagnetic spectrum within the 400 to 760 nm ranges. The different light sources are identified as daylight and artificial lights, with many types of lamps under the latter. As regards artificial lighting, a lighting fitting has two functions: redistributes luminescence properly and provides a suitable receptacle for the lamp. The requirements when using artificial or natural light in an exterior or interior setting are enumerated. The book also explains the specifications of the amount of light and how this amount is calculated. Interior lighting, both from artificial and natural sources, is comprehensively discussed, including issues such as discomfort glare, reflected glare, design and aesthetics, lighting requirements in different kinds of buildings, and flammability properties. The text also tackles exterior lighting including decorative floodlights, lighting for tunnels and underpasses, and special problem areas. Architects, engineers, electricians, interior designers, lighting technicians, environmentalists, and readers with interest in home decor will find this book useful.

Gravity's Engines

How Bubble-Blowing Black Holes Rule Galaxies, Stars, and Life in the Cosmos

One of The Barnes and Noble Review Editors' Picks: Best Nonfiction of 2012 Selected by The Christian Science Monitor as one of "21 smart nonfiction titles we think you'll enjoy this summer" Selected by The New Scientist as one of 10 books to look out for in 2012 We've long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. They're mysterious chasms so destructive and unforgiving that not even light can escape their deadly wrath. Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity's Engines, these chasms in space-time don't just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter. Black holes blow bubbles. With clarity and keen intellect, Scharf masterfully explains how these bubbles profoundly rearrange the cosmos around them. Engaging with our deepest questions about the universe, he takes us on an intimate journey through the endlessly colorful place we call our galaxy and reminds us that the Milky Way sits in a special place in the cosmic zoo—a "sweet spot" of properties. Is it coincidental that we find ourselves here at this place and time? Could there be a deeper connection between the nature of black holes and their role in the universe and the phenomenon of life? We are, after all, made of the stuff of stars.

Communications and Revelations From Another Reality

This, the second book in the Beyond Trilogy, expands on John and Katie's experiences and photographs of the orb phenomena covered in their first book. It reveals astounding new photographs and opens up exciting new questions about the whole nature of paranormal phenomena in general. John and Katie's photographs of orbs, angels and other apparitions have brought them into worldwide contact with other experiencers and researchers: it is from this basis that they now take a major step beyond the visible photographable phenomena, and current New Age notions about orbs, to reveal new insights about the paranormal. Could it be that orbs are the indicators of a wider, "beyond" reality? Is the symbology of orbs as images of oneness, drawing our attention to the most important orb of all: the orb of Earth on which we all live? Their ongoing photographs, personal experiences, and the amazing synchronistic events they found themselves part of reveal a conscious, purposeful phenomena that can interact with us as individuals, whoever and wherever we are. This inevitably leads to a spiritual perspective that crosses all religious and cultural boundaries, helping us to see that this one blue orb of Earth on which we all live, is greater than all that divides us! Orbs & Beyond is the vital visual link between Beyond Photography, and the forthcoming Beyond Reality.
