Book Description
This book was written to show that light is a primal element of life. All life originates and develops under the influence of the light of the sun, that "super terrestrial natural force" (Goethe). Sunlight influences the vital processes not onlyofthe plant (e. g. , heliotropism, photosynthesis) and the animal (e. g. , color change, maturation of the gonads) but of man as well. The human organism too reacts "heliotropically," as the 24 hour rhythm of the sleep-waking cycle demonstrates. of Artists have always perceived clearly the intensive stimulatory effect sunlight on their activity. One is reminded here ofCesare Lombroso, who wrote to his daughter "that thoughts come in the greatest profusion when (my) room is flooded with the sun's rays. " Richard Wagner exclaimed: "Ifonly the sun would come out, I would have the score finished in no time. " Bernard Shaw had a little cottage where he worked that could be turned according to the position of the sun. The composer Humperdinck wrote: "The sun is indispensable for my work; that is why it is important for me to have my study face east or south. " As these few examples indicate, it is above all those active in the arts who intuitively grasp the positive influence of sunlight on the psycho-physical effi ciency of their organism. In an age, however, when fluorescent lighting turns night into day, we are in danger of forgetting that man is a creature of nature as well as of culture.

Book Description
This book is designed to help students organize their thinking about psychology at a conceptual level. The focus on behaviour and empiricism has produced a text that is better organized, has fewer chapters, and is somewhat shorter than many of the leading books. The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section.

Book Description
A lively account of our age-old quest for brighter colors, which changed the way we see the world, from the best-selling author of Proof: The Science of Booze From kelly green to millennial pink, our world is graced with a richness of colors. But our human-made colors haven't always matched nature's kaleidoscopic array. To reach those brightest heights required millennia of remarkable innovation and a fascinating exchange of ideas between science and craft that's allowed for the most luminous manifestations of our built and adorned world. In Full Spectrum, Rogers takes us on that globe-trotting journey, tracing an arc from the earliest humans to our digitized, synthesized present and future. We meet our ancestors mashing charcoal in caves, Silk Road merchants competing for the best ceramics, and textile artists cracking the centuries-old mystery of how colors mix, before shooting to the modern era for high-stakes corporate espionage and the digital revolution that's rewriting the rules of color forever. In prose as vibrant as its subject, Rogers opens the door to Oz, sharing the liveliest events of an expansive human quest--to make a brighter, more beautiful world--and along the way, proving why he's "one of the best science writers around."* *National Geographic

Book Description
Visual Perception explores fundamental topics underlying the field of visual perception, including the perception of brightness and color, the physics of light, and the optics of the eye. Although the text leans heavily on physical and physiological concepts, explanations of the relevant physics and physiology are considered. This book is organized into 16 chapters and begins with an overview of the relationship between information assimilation and the physiology of the visual system based on data gathered both in physiological and perceptual experiments. More specifically, this text discusses the nature of the human perceptual system in terms of the kinds of information that are assimilated from the world, and how this selection of information is governed by the structure of receptors and the neural circuits that are connected to them. The relationships between symbols and their corresponding physical and physiological variables are also examined. Finally, the book addresses the presence of strong lateral inhibition in the visual system and how it fits the concept of evolution. This book is aimed at undergraduate and graduate students, regardless of their academic backgrounds.

Book Description
By reading this book, you will develop the skills to perceive a space and its contents in light, and be able to devise a layout of luminaires that will provide that lit appearance. Written by renowned lighting expert Christopher (Kit) Cuttle, the book: explains the difference between vision and perception, which is the distinction between providing lighting to make things visible, and providing it to influence the appearance of everything that is visible; demonstrates how lighting patterns generated by three-dimensional objects interacting with directional lighting are strongly influential upon how the visual perception process enables us to recognize object attributes, such as lightness, colourfulness, texture and gloss; reveals how a designer who understands the role of these lighting patterns in the perceptual process may employ them either to reveal, or to subdue, or to enhance the appearance of selected object attributes by creating appropriate spatial distributions of light; carefully explains calculational techniques and provides easy-to-use spreadsheets, so that layouts of lamps and luminaires are derived that can be relied upon to achieve the required illumination distributions. Practical lighting design involves devising three-dimensional light fields that create luminous hierarchies related to the visual significance of each element within a scene. By providing you with everything you need to develop a design concept - from the understanding of how lighting influences human perceptions of surroundings, through to engineering efficient and effective lighting solutions – Kit Cuttle instills in his readers a new-found confidence in lighting design.
