See the colors of the rainbow in a whole new light!
We live in a world of optical marvels - from the commonplace but beautiful rainbow, to the rare and eerie superior mirage. But how many of us really understand how a rainbow is formed, why the setting sun is red and flattened, or even why the sky at night is not absolutely black? This beautiful and informative guide provides clear explanations to all naturally occurring optical phenomena seen with the naked eye, including shadows, halos, water optics, mirages and a host of other spectacles. Separating myth from reality, it outlines the basic principles involved, and supports them with many figures and references. A wealth of rare and spectacular photographs, many in full color, illustrate the phenomena throughout. In this new edition of the highly-acclaimed guide to seeing, photographing and understanding nature's optical delights, the authors have added over 50 new images and provided new material on experiments you can try yourself.
Between the turn of the twentieth century and the Brown v. Board of Education decision in 1954, the way that American schools taught about "race" changed dramatically. This transformation was engineered by the nation's most prominent anthropologists, including Franz Boas, Ruth Benedict, and Margaret Mead, during World War II. Inspired by scientific racism in Nazi Germany, these activist scholars decided that the best way to fight racial prejudice was to teach what they saw as the truth about race in the institution that had the power to do the most good-American schools. Anthropologists created lesson plans, lectures, courses, and pamphlets designed to revise what they called "the 'race' concept" in American education. They believed that if teachers presented race in scientific and egalitarian terms, conveying human diversity as learned habits of culture rather than innate characteristics, American citizens would become less racist. Although nearly forgotten today, this educational reform movement represents an important component of early civil rights activism that emerged alongside the domestic and global tensions of wartime.Drawing on hundreds of first-hand accounts written by teachers nationwide, Zoe Burkholder traces the influence of this anthropological activism on the way that teachers understood, spoke, and taught about race. She explains how and why teachers readily understood certain theoretical concepts, such as the division of race into three main categories, while they struggled to make sense of more complex models of cultural diversity and structural inequality. As they translated theories into practice, teachers crafted an educational discourse on race that differed significantly from the definition of race produced by scientists at mid-century.Schoolteachers and their approach to race were put into the spotlight with the Brown v. Board of Education case, but the belief that racially integrated schools would eradicate racism in the next generation and eliminate the need for discussion of racial inequality long predated this. Discussions of race in the classroom were silenced during the early Cold War until a new generation of antiracist, "multicultural" educators emerged in the 1970s.
In the United States, as in many parts of the world, people are discriminated against based on the color of their skin. This type of skin tone bias, or colorism, is both related to and distinct from discrimination on the basis of race, with which it is often conflated. Preferential treatment of lighter skin tones over darker occurs within racial and ethnic groups as well as between them. While America has made progress in issues of race over the past decades, discrimination on the basis of color continues to be a constant and often unremarked part of life. In Color Matters, Kimberly Jade Norwood has collected the most up-to-date research on this insidious form of discrimination, including perspectives from the disciplines of history, law, sociology, and psychology. Anchored with historical chapters that show how the influence and legacy of slavery have shaped the treatment of skin color in American society, the contributors to this volume bring to light the ways in which colorism affects us all--influencing what we wear, who we see on television, and even which child we might pick to adopt. Sure to be an eye-opening collection for anyone curious about how race and color continue to affect society, Color Matters provides students of race in America with wide-ranging overview of a crucial topic.
The introduction of artificial lighting extends the time of wakefulness after dark and enables work at night, thus disturbing the human circadian rhythm. The understanding of the physiological mechanisms of visual and non-visual systems may be important for the development and use of proper light infrastructure and light interventions for different workplace settings, especially for shift work conditions. Visual and Non-Visual Effects of Light: Working Environment and Well-Being presents the impact of lighting in the working environment on human health, well-being and visual performance. The physiological explanation of the visual and non-visual effects of light on humans which discusses the biological bases of image and non-image forming vision at the cellular level may be of particular interest to any professional in the field of medicine, physiology, and biology. It is one of the intentions of this book to put forward some recommendations and examples of lighting design which take into account both the visual and non-visual effects of light on humans. These may be of particular interest to any professional in the field of lighting, occupational safety and health, and interior design. "What effects on health can a light ‘overdose’ or light deficiency have? What is bad light? The authors of the monograph provide answers to these questions. Just as for a physicist, the dual nature of light comprises an electromagnetic wave and a photon, the duality of light for a physician comprises visual and non-visual effects." --------------------------------------------------------Prof Jacek Przybylski, Medical University of Warsaw "This is a unique publication in the field of lighting technology. The authors have skillfully combined both the technical and biomedical aspects involved, which is unprecedented in the literature available. As a result, an important study has been created for many professional groups, with a significant impact on the assessment of risks associated with LED sources." --------------------------------------------Prof Andrzej Zając, Military University of Technology, Warsaw
The intent of this book is to offer for primary school teachers a clear and condensed explanation of the Bradley System of Color Instruction. This system relies on Maxwell rotating color disks to determine and define pigmentary standards.
THE SUNDAY TIMES BESTSELLER 'A mind-expanding tour of the world without leaving your paintbox. Every colour has a story, and here are some of the most alluring, alarming, and thought-provoking. Very hard painting the hallway magnolia after this inspiring primer.' Simon Garfield The Secret Lives of Colour tells the unusual stories of the 75 most fascinating shades, dyes and hues. From blonde to ginger, the brown that changed the way battles were fought to the white that protected against the plague, Picasso's blue period to the charcoal on the cave walls at Lascaux, acid yellow to kelly green, and from scarlet women to imperial purple, these surprising stories run like a bright thread throughout history. In this book Kassia St Clair has turned her lifelong obsession with colours and where they come from (whether Van Gogh's chrome yellow sunflowers or punk's fluorescent pink) into a unique study of human civilisation. Across fashion and politics, art and war, The Secret Lives of Colour tell the vivid story of our culture.
"This book is a unified artistic-literary, interpretive commentary on the Latter Prophets (Nevi'im Acharonim) section of the Hebrew Bible. It attempts to express the ecstatic poetic narrative and mind-altering visions of the Hebrew Prophets in a distinctlt Jewish midrashic--yet unique--manner, deriving multiple visionary images from multiple translations of the original Hebrew text, and then retranslating the derived fused images back into a fresh literary biblical analysis"--introduction, p. xix.
