Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's new introduction places both Feynman's book and his seminal contribution to QED in historical context and further highlights Feynman's uniquely appealing and illuminating style.

Modern Welding is a comprehensive text that has long been the standard for teaching the theory, fundamentals, equipment, and techniques of welding technology. The 2004 edition includes coverage of new processes, such as friction stir welding, and has been reorganized to place stronger emphasis on the more-widely used arc processes. In addition to covering all welding and cutting processes, the text includes thorough coverage of welding symbols, testing and inspecting, and getting a job in the welding industry.The Lab Manual contains activities that are designed to help students review content and develop critical thinking skills. A wide variety of activities is provided for various learning styles.

Accurate, authoritative and comprehensive, Optics, Fourth Edition has been revised to provide readers with the most up-to-date coverage of optics. The market leader for over a decade, this book provides a balance of theory and instrumentation, while also including the necessary classical background. The writing style is lively and accessible.

Optics--a field of physics focusing on the study of light--is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. The Optics of Life introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. Sönke Johnsen starts with the basics, describing the properties of light and the units and geometry of measurement. He then explores how light is created and propagates and how it interacts with matter, covering topics such as absorption, scattering, fluorescence, and polarization. Johnsen also provides a tutorial on how to measure light as well as an informative discussion of quantum mechanics. The Optics of Life features a host of examples drawn from nature and everyday life, and several appendixes that offer further practical guidance for researchers. This concise book uses a minimum of equations and jargon, explaining the basic physics of light in a succinct and lively manner. It is the essential primer for working biologists and for anyone seeking an accessible introduction to optics.

The story of light affects us every day of our lives...In highly visual, entertaining and easy-to-understand language, famed science writer Ben Bova explains the many ways light affects our minds, bodies and universe.--Why do people kiss with their eyes closed?--What exactly is quantum physics?--Why is it difficult to swat a mosquito?--Is the universe expanding or contracting?--How do lasers work?--What do we "see" when we dream?In this all-encompassing work, one of the most noted science fiction as well as nonfiction writers of our time explores the subject of light and shows how it has shaped every aspect of our existence. From the creation of life to the exploration of the heavens and the stars, from the origins of the earth to the possibility of life on distant planets, Ben Bova unveils the beauty and science behind this phenomenon. Dr. Bova masterfully explains how light affects us every day of our lives, from our religions to our sex drives, as well as how we use light in art, science, industry, entertainment, cosmetics, jewelry and much more."The enlightenment of discoveries and the brilliance of Ben Bova combine to enable our minds to glimpse the majesty of the infinite worlds of light in the universe."--Buzz Aldrin"Superbly written--a banquet of topics served by a master literary chef!"--Bill Pogue, Skylab astronaut"The Story of Light is a light-hearted, enlightened romp through many facets of human experience, reflected and refracted through Bova's bright, polychromatic mind."--David Grinspoon, Principal Scientist, Southwest Research Institute and author of Venus Revealed

This is a comprehensive, applications-oriented introduction to geometrical optics, wave optics, and modern optics. Contains new chapters on laser beam characteristics and nonlinear optics; expanded coverage of fiber optics; new sections on ray tracing, thick lens, the Doppler effect, and evanescent waves; and valuable coverage of matrix treatment of polarization, Fraunhofer diffraction, Fourier optics, and more. An ideal introductory guide for the physics instructor, specifically those concentrating on optics.
