Stray Reflections

When asked "What is the goal of a writer?" author Anne Lamott responded, "To help others have this sense of wonder, of seeing things anew, things that can catch us off guard, that break in on our small, bordered worlds."This is what Jawad Mian achieves with Stray Reflections, an intimate account of his journey through life and lessons learned along the way. He delivers distilled infusions of clarity and inspiration in short chapters for reading in quiet moments at home or at the office.In his own search for meaning, Jawad draws from such sources as Rumi, Emerson, Goethe, Buddha, Confucius, Seneca, and many others. To read Stray Reflections is to be immersed in the timeless wisdom of the great poets, saints, and philosophers. This book is an antidote to the great angst of modern life.

New chapters and updates highlight the second edition of Laser Safety: Tools and Training. This text provides background information relating to lasers and laser safety, and examines the components of laser work and laser safety from a different perspective. Written by a working laser safety officer, the book considers ways to keep users, as well as those around them, safe. The author encourages readers to think beyond protective eyewear. As it relates to safety, he determines that if eyewear is required, then the laser system is not ideal. This book factors in optics, the vibration elements of the optical table, the power meter, and user training, elements that are not commonly considered in the context of laser safety. It presents ways for users to evaluate the hazards of any laser procedure and ensure that they are following documented laser safety standards. The material serves as a fundamental means or road map for laser users seeking to utilize the safest system possible. What’s New in the Second Edition: The second edition provides an inclusion of the Z136.8 Research Laser Standard, and offers updates and an explanation of eye exposure limits (MPE), presents new cases studies, and presents practical example images. It includes coverage of, laser lab design lessons, addresses user facility challenges and laser disposal. Presents case studies of real accidents, preventive measures, and templates for documenting potential laser risks and attendant safety measures Reviews factors often overlooked when one is setting up a laser lab Demonstrates how to investigate a laser incident This text which includes fundamental laser and laser safety information, as well as critical laser use information, is appropriate for both the novice and the seasoned professional.

Introduction to Laser Science and Engineering provides a modern resource for a first course in lasers for both students and professionals. Starting from simple descriptions, this text builds upon them to give a detailed modern physical understanding of the concepts behind light, optical beams and lasers. The coverage starts with the nature of light and the principles of photon absorption and transmission, leading to the amplified and stimulated emission principals governing lasers. The specifics of lasers and their application, safe use and future prospects are then covered, with a wealth of illustrations to provide readers with a visual sense of optical and laser principles.
