Jeff Hecht: City of Light : The Story of Fiber Optics

Description

City of Light tells the story of fiber optics, tracing its transformation from 19th-century parlor trick into the foundation of our global communications network. Written for a broad audience by a journalist who has covered the field for twenty years, the book is a lively account of both the people and the ideas behind this revolutionary technology. The basic concept underlying fiber optics was first explored in the 1840s when researchers used jets of water to guide light in laboratory demonstrations. The idea caught the public eye decades later when it was used to create stunning illuminated fountains at many of the great Victorian exhibitions. The modern version of fiber optics-using flexible glass fibers to transmit light-was discovered independently five times through the first half of the century, and one of its first key applications was the endoscope, which for the first time allowed physicians to look inside the body without surgery. Endoscopes became practical in 1956 when a college undergraduate discovered how to make solid glass fibers with a glass cladding. With the invention of the laser, researchers grew interested in optical communications. While Bell Labs and others tried to send laser beams through the atmosphere or hollow light pipes, a small group at Standard Telecommunication Laboratories looked at guiding light by transparent fibers. Led by Charles K. Kao, they proposed the idea of fiber-optic communications and demonstrated that contrary to what many researchers thought glass could be made clear enough to transmit light over great distances. Following these ideas, Corning Glass Works developed the first low-loss glass fibers in 1970. From this point fiber-optic communications developed rapidly. The first experimental phone links were tested on live telephone traffic in 1977 and within half a dozen years long-distance companies were laying fiber cables for their national backbone systems. In 1988, the first transatlantic fiber-optic cable connected Europe with North America, and now fiber optics are the key element in global communications. The story continues today as fiber optics spread through the communication grid that connects homes and offices, creating huge information pipelines and replacing copper wires. The book concludes with a look at some of the exciting potential developments of this technology.

Winston Churchill: The Second World War: the Hinge of Fate: Volume IV

Description

THE HINGE OF FATE marks in Sir Winston Churchill's words, 'the turning-point of the Second World War.' It details a period during which almost uninterrupted defeat gave way to almost unbroken success for the Allies. While the Afrika Korps advanced almost to the outskirts of Alexandria and the Japanese struck by land and by sea, despair came to all but the most resolute. However, from this nadir there followed an ever-steady climb. Rommel was thrown back and defeated at Alamein. The British fought shoulder to shoulder for the first time with their American allies in North Africa and the tide turned in the Pacific.

The Miracle of Analogy is the first of a two-volume reconceptualization of photography. It argues that photography originates in what is seen, rather than in the human eye or the camera lens, and that it is the world's primary way of revealing itself to us. Neither an index, representation, nor copy, as conventional studies would have it, the photographic image is an analogy. This principle obtains at every level of its being: a photograph analogizes its referent, the negative from which it is generated, every other print that is struck from that negative, and all of its digital "offspring." Photography is also unstoppably developmental, both at the level of the individual image and of medium. The photograph moves through time, in search of other "kin," some of which may be visual, but others of which may be literary, architectural, philosophical, or literary. Finally, photography develops with The Second World War: the Hinge of Fate: Volume IV free epub us, and in response to us. It assumes historically legible forms, but when we divest them of their saving power, as we always seem to do, it goes elsewhere.The present volume focuses on the nineteenth century and some of its contemporary progeny.

John Firman,Ann Gila: A Psychotherapy of Love: Psychosynthesis in Practice

Description

This book shows what psychosynthesis looks like in the empirical practice of psychotherapy. Originally conceived by Italian psychiatrist Robert Assagioli, psychosynthesis is one of the first Western psychologies that addresses both spiritual and psychological healing and growth through self-realization. In effect, it offers an approach to psychotherapy founded in altruistic love, and the nurturing that supports the innate drive within human beings to embrace and actualize the whole of who they are. Authors John Firman and Ann Gila include experientially based models and theory, case studies from both the client and therapist perspectives, and an invitation for both the professional and the layperson to the self-reflection, inner work, and commitment necessary to love and work at this depth. After an overview of the fundamentals of psychosynthesis theory, the authors explore how a therapist's own embrace of these ideas can foster an altruistic, empathetic love that supports and improves therapist-client rapport and progress.
