Harnessing Light

Optical science and engineering affect almost every aspect of our lives. Millions of miles of optical fiber carry voice and data signals around the world. Lasers are used in surgery of the retina, kidneys, and heart. New high-efficiency light sources promise dramatic reductions in electricity consumption. Night-vision equipment and satellite surveillance are changing how wars are fought. Industry uses optical methods in everything from the production of computer chips to the construction of tunnels. Harnessing Light surveys this multitude of applications, as well as the status of the optics industry and of research and education in optics, and identifies actions that could enhance the field's contributions to society and facilitate its continued technical development.

Light Touches: Cultural Practices of Illumination, 1800-1900 explores how urban lives in the nineteenth century were increasingly touched by innovations in the technologies and aesthetics of illumination. Dramatic changes in qualities of light – and darkness – became acutely palpable to the human sensorium; using, seeing, feeling, and being in light were now matters of intense personal and cultural concern. Light gave meaningful vitality to the period’s material culture, and light itself became something to be perceptually consumed. Over the course of six chapters Alice Barnaby traces how light was used in amateur artistic pastimes, interior design and clothing fashions, spectacular public amusements, volatile street demonstrations, and art gallery designs. From these previously unexplored examples a more complex history of light in the period emerges. Society’s fascination with illumination, its desire to work with it and make meaning from it gave rise to a distinctly new set of cultural practices. Through these practices unexpected discoveries about the modern world were revealed. Light proved to be instrumental in everyday acts of experimentation and imaginative enquiry. Barnaby offers an intervention into the dominant scholarly narrative of the nineteenth century which traditionally reads modernity as synonymous with the formation of a spectacular, disembodied visuality. Light Touches, in contrast, returns vision to the body and foregrounds the actively felt - as well as seen - sensation of light. In coming to understand these cultural practices of illumination, the book reconsiders many assumptions about nineteenth-century modernity.

Biochemistry is an invaluable and user-friendly resource.This innovative text for non-biochemistry majors includes:* Introductory material at the beginning of each chapter that contextualizes chapter themes in real-life scenarios* Clear list of objectives for each chapter* Online supporting materials with further opportunities for research and investigation* Synthesis questions at the end of each chapter that encourage students to make connections between concepts and ideas, as well as develop critical-thinking skills

This volume describes an impressive array of the current photonic-related technologies being used in the investigation of biological systems. The topics include various types of microscopy (fluorescence correlation microscopy, two-photon microscopy), sensitive detection of biological molecules, nano-surgery techniques, fluorescence resonance energy transfer, nano-plasmonics, terahertz spectroscopy, and photosynthetic energy conversion. The emphasis is on the physical principles behind each technique, and on examining the advantages and limitations of each.The book begins with an overview by Paras Prasad, a leader in the field of biophotonics, of several important optical techniques currently used for studying biological systems. In the subsequent chapters these techniques are discussed in depth, providing the reader with a detailed understanding of the basic physical principles at work. An excellent treatment of terahertz spectroscopy demonstrates how photonics is being extended beyond the visible region. Recent results in the use of femtosecond lasers as a tool to porate cell walls demonstrate that the manipulation of light can be used as a tool for the study and the treatment of biological systems. The field of Bio-photonics is broad and still growing, so cannot be covered comprehensively in one volume. But here the reader will find an introduction to some of the major tools used for studying biological systems, and at the same time a detailed, first-principles treatment of the physics behind these tools.

Biomimicry for Materials, Design and Habitats: Innovations and Applications and is a survey of the recent work of recognized experts in a variety of fields who employ biomimicry and related paradigms to solve key problems of interest within design, science, technology, and society. Topics covered include innovations from biomimicry in materials, product design, architecture, and biological sciences. The book is a useful resource for educators, designers, researchers, engineers, and materials scientists, taking them from the theory behind biomimicry to real world applications. Living systems have evolved innovative solutions to challenges that humans face on a daily basis. Nonlinear multifunctional systems that have a symbiotic relationship with their environment are the domain of nature. Morphological solutions for buildings inspired by nature can be used for skins, surfaces, and structures to facilitate environmental adaptation of buildings to increase occupant comfort and reduce energy demands. Birds can teach us to produce novel structures, 3D printing can be informed by oysters and mussels, and mycelium may show us the way to fabricate new biocomposites in architecture. Therefore, it is in nature that we seek inspiration for the solutions to tomorrow’s challenges. Presents new directions in education and the various applications of biomimicry within industry, including bio-inspired entrepreneurship Discusses the role of biomimicry in education, innovation, and product design Covers applications in systems engineering and design, novel materials with applications in 3D printing, and bio-inspired architecture Includes perspectives on sustainability detailing the role that bio-inspiration or biomimicry plays in sustainability
