Do Colors Exist

Why do polished stones look wet? How does the Twin Paradox work? What if Jupiter were a star? How can we be sure that pi never repeats? How does a quantum computer break encryption? Discover the answers to these, and other profound physics questions! This fascinating book presents a collection of articles based on conversations and correspondences between the author and complete strangers about physics and math. The author, a researcher in mathematical physics, responds to dozens of questions posed by inquiring minds from all over the world, ranging from the everyday to the profound. Rather than unnecessarily complex explanations mired in mysterious terminology and symbols, the reader is presented with the reasoning, experiments, and mathematics in a casual, conversational, and often comical style. Neither over-simplified nor over-technical, the lucid and entertaining writing will guide the reader from each innocent question to a better understanding of the weird and beautiful universe around us. Advance praise for Do Colors Exist?: “Every high school science teacher should have a copy of this book. The individual articles offer enrichment to those students who wish to go beyond a typical ‘dry curriculum’. The articles are very fun. I probably laughed out loud every 2-3 minutes. This is not easy to do. In fact, my children are interested in the book because they heard me laughing so much.” – Ken Ono, Emory University

In Colors Passing Through Us, Marge Piercy is at the height of her powers, writing about what matters to her most: the lives of women, nature, Jewish ritual, love between men and women, and politics, sexual and otherwise. Feisty and funny as always, she turns a sharp eye on the world around her, bidding an exhausted farewell to the twentieth century and singing an "electronic breakdown blues" for the twenty-first. She memorializes movingly those who, like los desaparecidos and the victims of 9/11, disappear suddenly and without a trace. She writes an elegy for her mother, a woman who struggled with a deadening round o fhousework, washin gon Monday, ironing on Tuesday, and so on, "until stroke broke/her open." She remembers the scraps of lace, the touch of velvet, that were part of her maternal inheritance and fist aroused her sensual curiosity. Here are paeans to the pleasures of the natural world (rosy ripe tomatoes, a mating dance of hawks) as the poet confronts her own mortality in the cycle of seasons and the eternity of the cosmos: "iam hurrying, I am running hard / toward I don't know what, / but I mean to arrive before dark." Other poems--about her grandmother's passage from Russia to the New World, or the interrupting of a Passover seder to watch a comet pass--expand on Piercy's appreciation of Jewish life that won her so much acclaim in The Art of Blessing the Day. Colors Passing Through Us is a moving celebration of the endurance of love an dof the phenomenon of life itself--a book to treasure.

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, acidyellow 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, TheSecret Lives of Colour tell the vivid story of our culture.

During the first two decades of the nineteenth century, two of the most significant theoretical works on color since Leonardo da Vinci's Trattato della Pittura were written and published in Germany: Arthur Schopenhauer's On Vision and Colors and Philipp Otto Runge's Color Sphere. For Schopenhauer, vision is wholly subjective in nature and characterized by processes that cross over into the territory of philosophy. Runge's Color Sphere and essay "The Duality of Color" contained one of the first attempts to depict a comprehensive and harmonious color system in three dimensions. Runge intended his color sphere to be understood not as a product of art, but rather as a "mathematical figure of various philosophical reflections." By bringing these two visionary color theories together within a broad theoretical context—philosophy, art, architecture, and design—this volume uncovers their enduring influence on our own perception of color and the visual world around us.

'A Naïve Realist Theory of Colour' defends the view that colours are mind-independent properties of things in the environment. Keith Allen argues that a naïve realist theory of colour best explains how colours appear to perceiving subjects, and that this view is not undermined by our modern scientific understanding of the world.

An experimental approach to the study and teaching of color is comprised of exercises in seeing color action and feeling color relatedness before arriving at color theory.

Awarded the 1986 Johnsonian Prize in Philosophy. This work on colour features a chapter, 'Further Thoughts: 1993', in which the author revisits the dispute between colour objectivists and subjectivists from the perspective of the ecology, genetics, and evolution of colour vision.
