The first half of the book deals with classical physical optics; the second principally with the quantum nature of light. Chapters 1 and 2 treat the propagation of light waves, including the concepts of phase and group velocities, and the vectorial nature of light. Chapter 3 applies the concepts of partial coherence and coherence length to the study of interference, and Chapter 4 takes up multiple-beam interference and includes Fabry-Perot interferometry and multilayer-film theory. Diffraction and holography are the subjects of Chapter 5, and the propagation of light in material media (including crystal and nonlinear optics) are central to Chapter 6. Chapters 7 and 8 introduce the quantum theory of light and elementary optical spectra, and Chapter 9 explores the theory of light amplification and lasers. Chapter 10 briefly outlines ray optics in order to introduce students to the matrix method for treating optical systems and to apply the ray matrix to the study of laser resonators.Many applications of the laser to the study of optics are integrated throughout the text. The author assumes students have had an intermediate course in electricity and magnetism and some advanced mathematics beyond calculus. For classroom use, a list of problems is included at the end of each chapter, with selected answers at the end of the book.

    She had left Missouri and come to Green River, Wyoming to find her father. Now, she was being held by two men against her will. The man who was determined to find her was a rancher. A rancher with a debt to repay.

    The book s two-part coverage organizes topics under basic theory, and assembles an arsenal of approximation schemes with illustrative applications. For physicists and engineers. "

    The book includes full discussions of many problems of current interest which are not treated in any extant book, and all these matters are considered with perception and understanding."—S. Chandrasekhar "A tour de force: lucid, straightforward, mathematically rigorous, exacting in the analysis of the theory in its physical aspect."—L. P. Hughston, Times Higher Education Supplement"Truly excellent. . . . A sophisticated text of manageable size that will probably be read by every student of relativity, astrophysics, and field theory for years to come."—James W. York, Physics Today

    These sections together make an appropriate one-term advanced/graduate level course (mathematical prerequisites: vector analysis and simple partial-differential equations). The book is printed to make it easy for readers to identify these sections.• The remaining Track 2 material provides a wealth of advanced topics instructors can draw from to flesh out a two-term course, with Track 1 sections serving as prerequisites.

    We are not alone, nor have we been creating life experiences on our own. There is a co-creative Universal Intelligence who is very much involved and continually seeking a dialogue. The problem is not so much the life challenges, but our own individual lack of communication with our co-creator. A conversation is happening all of the time, but we must open our eyes and ears to it. When we do, an opportunity to reconnect with the lighter side of life ensues. We do not have to get wrapped up in the heaviness. Instead of becoming overwhelmed by the issues at hand, we can become aware of the answers and solutions constantly presenting themselves. The Universe wants us to be joyful, have fun, and let go. The synchronicities, symbols, and messages are always intended to guide us. They are there to make us smile, to stop to remember there is more to life than the current object of our perceptions. Instead of having to work things out, we can play them out, yielding more aligned outcomes and a greater experience. When we are able to remember the vast connection that exists, the illusions we live become more and more apparent. Greater awareness of the messages and engagement in the dialogue allows us to laugh with the heavens at ourselves at life and our seriousness.

    The Sound of Gravity is a harrowing, dramatic and powerful tale of love, loss and redemption as that haunting split-second memory changes the course of a lifetime. Trapped high on a stormbound mountain face in the icy depths of winter, the stricken young man is forced to fight for his life. Half a lifetime later, haunted by grief and guilt, Patrick is freed from his self-imposed vigil when at last the mountain releases his heart-rending secret.

    On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions.Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

    Timothy Ferris provides a clear, elegantly written overview of current research and a forecast of where cosmological theory is likely to go in the twenty-first century. He explores the questions that have occurred to even casual readers -- who are curious about nature on the largest scales: What does it mean to say that the universe is "expanding," or that space is "curved"? -- and sheds light on the possibility that our universe is only one among many universes, each with its own physical laws and prospects for the emergence of life.
