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 the recipient of the 2009 Nobel Prize in Physics, 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.

The sacred city of Banāras on the River Ganges is one of the oldest living cities in the world—as old as Jerusalem, Athens, and Peking. It is the place where Shiva, the Lord of All, is said to have made his permanent home since the dawn of creation. There are few cities in India as traditionally Hindu and as symbolic of the whole of Hindu culture as Banāras. In this eloquent, finely observed study, Diana Eck shows how the city over the centuries has become a lens through which the Hindu vision of the world is precisely focused. She reveals the spiritual and historical resonance of this holy place where great sages such as the Buddha and Shankara were taught, where ashrams, palaces, and universities were built, where God has been imagined and imagined in a thousand ways. She describes the rites of its temples, the busy life of its riverfront, and the exuberance of its festivals. She tells how people travel from all over India to Banāras for the privilege of dying a good death here, for they believe that on the banks of the River Ganges where “the atmosphere of devotion is improbable in its strength,” it is possible to be released from the earthly round forever. In her account of the sacred history, geography, and art of the city, its elaborate and thriving rituals, its myths and literature, and its importance to pilgrims and seekers, Diana Eck uses her wealth of scholarship to make the Hindu tradition come powerfully alive so that we come to understand the meaning of this sacred city to the millions of believers who have been coming here for over 2,500 years.

City of Light joins the recent reissues of four of Cyrus Colter's books by TriQuarterly Books/Northwestern University Press. Colter concludes his grand literary project with a work that is foremost a novel of ideas. Though City of Light may appear realistic in setting (contemporary Paris), with a well-differentiated cast of believable moment, each character nonetheless represents an idea or a position regarding the issue of race in American life. The ideas or positions range from black nationalism, drawing upon African models and an Afrocentric political position, to complete assimilation, presented here by the central character's love affair with a white woman. Paul Kessey, at age twenty-nine, is caught between two worlds. Although his is a privileged world of successful blacks in Chicago, and he is a graduate of Princeton, handsome and well-connected, Kessey is uncertain how to identify himself in relation to the African diaspora, partly because of his own light skin. Throughout his Parisian sojourn, he is both attracted and repelled by different ideas, attitudes, and concepts regarding the place of blacks in a white society; he goes back and forth among the persons -- and the ideas they represent -- and thus among contradictory possibilities of life as a black man. By intertwining in an intricate web racial, class, and political issues with the intense struggles of one man's heart, Colter presents a vivid portrait of the personal effects of prejudice and its hypocrisies. City of Light remains a daring push against the grain of American literary fashion, both in its method and in treating interracial relationships, Afrocentrism, and the black middle class.

The volume is the first-ever book-length study of the cinematic representation of Paris in the films of German èmigrè filmmakers, many of whom fled there as a refuge from Hitler. In coming to Paris--a privileged site in terms of production, exhibition, and film culture--these experienced professionals also encountered resistance: hostility toward Germans, anti-Semitism, and boycotts from a French industry afraid of losing jobs to foreigners. Phillips juxtaposes the cinematic portrayal of Paris in the films of Robert Siodmak, Billy Wilder, Fritz Lang, Max Ophüls, Anatol Litvak, and others with the wider social and cultural debates about the city in cinema.

Bestselling author Marge Piercy celebrates the lives of the brave and dedicated women who changed the destiny of a nation in this novel set during the French Revolution For Claire Lacombe and Pauline Leon, two poor women of eighteenth-century France, the lofty ideals of the coming revolution could not seem more abstract. But when Claire sees the gaping disparity between the poverty she has known and the lavish lives of aristocrats as her theater group performs in their homes, and Pauline witnesses the execution of local bread riot leaders, both are driven to join the uprising. They, along with upper-class women like Madame Manon Roland, who ghostwrites speeches for her politician husband and runs a Parisian salon where revolutionaries gather, will play critical roles in the French people’s bloody battle for liberty and equality. Author Marge Piercy’s thrilling and scrupulously researched fictionalized account of these real women’s lives shines with emotional depth and strikingly animated action. By interweaving their tales with the exploits of men whose names have become synonymous with the revolution, like Robespierre and Danton, Piercy reveals how the contributions of these courageous women may be lesser known, but no less important. Rich in detail and broad in scope, City of Darkness, City of Light is a riveting portrayal of an extraordinary era and the women who helped shape an important chapter in history.
