It's 1962, a year after the death of Sam's father, Sam and her mother must move, along with their very liberal views, to Jackson, Mississippi. Needless to say, they don't quite fit in. As racism ensues, Sam learns to focus with her camera lens to bring forth the social injustice out of the darkness and into the light.
A comprehensive introduction to the burgeoning field of photonics The field of photonics is finding increasing applications across a broad range of industries. While many other books provide an overview of the subject, Fundamentals of Light Sources and Lasers closes a clear gap in the current literature by concentrating on the principles of laser operation as well as providing coverage of important concepts necessary to fully understand the principles involved. The scope of the book includes everything a professional needs to get up to speed in the field, as well as all the material necessary to serve as an excellent introductory laser course for students. Ideal for self-study as well as structured coursework, the book offers thorough coverage of: * The nature of light and atomic emission * Basic quantum mechanics and laser processes * Cavity optics, fast-pulse production, and nonlinear optical phenomena * Laser technology, including visible gas lasers, UV gas lasers, infrared gas lasers, solid-state lasers, semiconductor lasers and tunable dye lasers Extensive real-world case studies are included to help readers appreciate the practical applications of the material covered. *An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department.
This book gives an introduction to the working principles of high-intensity discharge (HID) lamps and points out challenges and problems associated with the development and operation of HID lamps. It is the most comprehensive book on gas discharge lamps, on the physical basics and realization. The state-of-the-art in electrode and plasma diagnostics as well as numerical methods used for the understanding of HID lamps are described.
McMullan pens a gripping story of ten-year-old Frank Russell, who comes of age too soon during the Civil War--a war that mercilessly robs Frank of a simpler way of life, his boyhood, his family, and his idealistic dreams.
In 1992, he began the series Light Sources, the focus of this volume, which critic Carol Squiers has described as "a trope for the seductions of the quickly glimpsed, the half remembered, the partially understood, qualities that Welling wants to hold up, examine and admire without piercing the fragile surface of their own fugitive grace.
Designed to provide the ideal solution for teaching junior science, "New Star Science 3" books are aimed at the third primary school year. These teacher's notes provide a background to the unit as well as photocopiables and assessment material. The focus of this text is "light and shadows".
Uses a simple and practical approach to cover typical components and design of ordinary, uncomplicated systems for building lighting basics. Both natural lighting and electrical lighting are included and both the Commission Internationale d'Eclairage and IESNA methods are introduced for daylighting calculations. An expanded version of the point method is shown that covers all orientations instead of only orthogonal relationships. Along with terms and fixtures commonly used in the profession, each chapter includes numerous examples, ending with exercises and study questions that enable readers to better understand the material.
