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.

This book reveals not only how the eye evolved into an organ of vision, but also describes how molecular mechanisms of key molecules operate in the phototransduction cascade. In this groundbreaking text, experts also explain mechanisms for sensing radiation outside of the visible wavelengths. Comprehensive and penetrating, the book brings together the mechanisms of the visual transduction cascade and is an invaluable text for everyone conducting research in the visual system.

The present book is based on the experience of the author. The experience is mainly the result of years of research, of consulting work, and in participation in policy decision making in many felds, most, but not all, related to outdoor lighting. To some degree, the book represents the preference of the author. The selection of the subjects is based on more than 50 years of experience of what is desirable to know for persons engaged in scientifc research or practical application in the felds of lighting and vision. The subjects deal with a number of fundamental aspects. The theorists must have them at their fngertips, whereas the practical engineers may assume them as known in their daily work. The selection of subjects is based in part by the questions that came to the author over the years, but even more by the preference of the author himself. In this respect, it is a personal book. Thus, it should be stressed that the book is not a ‘handbook’ or even a ‘textbook’; many subjects that commonly are treated in such books are not included here. Not because they lack importance, but because the author feels that they are adequately treated elsewhere. Some relevant works are mentioned in the References. Over the years, the author has been engaged in giving courses on vision and lighting, lately more in particular on Masterclasses on a post-graduate or post-doctorate level.

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

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.

Designing with Light: The Art, Science, and Practice of Architectural Lighting Design, Second Edition is perfect for architecture, interior design, and electrical engineering programs that include courses on lighting design, as well as professionals looking for a thorough and up-to-date desk reference.

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.

How does perception provide reasons for our empirical judgements? This volume offers a set of new essays which in different ways address this fundamental question, and investigate the implications for our understanding of perceptual experience.
