Light in Dark Objects exposes inner life in a kiss or in the movement of water on the shore of a lake. The poems speak from our true homes hidden beneath the surface of the world we see, from that river of memories and absences that is the true heart of things.
Describes properties of light and dark, color, shadows, and more; and includes experiments.
Discusses the basic science concept of light and darkness.
What’s in the dark? Countless generations have gazed up at the night sky and asked this question—the same question that cosmologists ask themselves as they study the universe. The answer turns out to be surprising and rich. The space between stars is filled with an exotic substance called “dark matter” that exerts gravity but does not emit, absorb, or reflect light. The space between galaxies is rife with “dark energy” that creates a sort of cosmic antigravity causing the expansion of the universe to accelerate. Together, dark matter and dark energy account for 95 percent of the content of the universe. News reporters and science journalists routinely talk about these findings using terms that they assume we have a working knowledge of, but do you really understand how astronomers arrive at their findings or what it all means? Cosmologists face a conundrum: how can we study substances we cannot see, let alone manipulate? A powerful approach is to observe objects whose motion is influenced by gravity. Einstein predicted that gravity can act like a lens to bend light. Today we see hundreds of cases of this—instances where the gravity of a distant galaxy distorts our view of a more distant object, creating multiple images or spectacular arcs on the sky. Gravitational lensing is now a key part of the international quest to understand the invisible substance that surrounds us, penetrates us, and binds the universe together. A Ray of Light in a Sea of Dark Matter offers readers a concise, accessible explanation of how astronomers probe dark matter. Readers quickly gain an understanding of what might be out there, how scientists arrive at their findings, and why this research is important to us. Engaging and insightful, Charles Keeton gives everyone an opportunity to be an active learner and listener in our ever-expanding universe. Watch a video with Charles Keeton: Watch video now.

Light pervades the world, and when it is not light, darkness emerges and is combated by electric illumination. Despite this globally shared human experience in which spaces appear radically different depending on time, season, and weather, social science investigation on the subject is meager. From Light to Dark fills this gap, focusing on our interaction with daylight, illumination, and darkness. Tim Edensor begins by examining the effects of daylight on our perception of landscape, drawing on artworks, particular landscapes, and architectural practice. He then considers the ways in which illumination is often contested and can be used to express power, looking at how capitalist, class, ethnic, military, and state power use lighting to reinforce their authority over space. Edensor also considers light artists such as Olafur Eliasson and festivals of illumination before turning a critical eye to the supposedly dangerous, sinister associations of darkness. In examining the modern city as a space of fantasy through electric illumination, he studies how we are seeking—and should seek—new forms of darkness in reaction to the perpetual glow of urban lighting. Highly original and absorbingly written, From Light to Dark analyzes a vast array of artistic interventions, diverse spaces, and lighting technologies to explore these most basic human experiences.
This book looks at the differences between light and dark. - Darkness is the absence of light. You can make a dark box to show how we need light to see. - Experiment using ice cubes in boxes to show that dark colours absorb more sunlight than light colours. - Look at how some animals have evolved to "e;see"e; in the dark using other senses and try it out yourself! And much more!
During his career as one of America's most sought-after illustrators, Andrew Loomis (1889-1959) taught at the American Academy of Art in Chicago, and in 1939 he codified his lessons in his first manual, Fun with a Pencil. Four years later it had already been through six printings, and he followed up over the next two decades with a series of even more successful how-to books that remain the gold standard for artists to this day. Creative Illustration is considered Loomis's magnum opus, which was aimed primarily at the professional-level illustrator. Divided into seven sections: Line, Tone, Color, Telling the Story, Creating Ideas, Fields of Illustration, and Experimenting and Studies, this book is filled with instructions, tips, insider experiences, and incredible illustrations.
