Book Description
Today complex numbers have such widespread practical use--from electrical engineering to aeronautics--that few people would expect the story behind their derivation to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year-old history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He recreates the baffling mathematical problems that conjured it up, and the colorful characters who tried to solve them. In 1878, when two brothers stole a mathematical papyrus from the ancient Egyptian burial site in the Valley of Kings, they led scholars to the earliest known occurrence of the square root of a negative number. The papyrus offered a specific numerical example of how to calculate the volume of a truncated square pyramid, which implied the need for i. In the first century, the mathematician-engineer Heron of Alexandria encountered I in a separate project, but fudged the arithmetic; medieval mathematicians stumbled upon the concept while grappling with the meaning of negative numbers, but dismissed their square roots as nonsense. By the time of Descartes, a theoretical use for these elusive square roots--now called "imaginary numbers"--was suspected, but efforts to solve them led to intense, bitter debates. The notorious i finally won acceptance and was put to use in complex analysis and theoretical physics in Napoleonic times. Addressing readers with both a general and scholarly interest in mathematics, Nahin weaves into this narrative entertaining historical facts and mathematical discussions, including the application of complex numbers and functions to important problems, such as Kepler's laws of planetary motion and ac electrical circuits. This book can be read as an engaging history, almost a biography, of one of the most evasive and pervasive "numbers" in all of mathematics.

Book Description
An extraordinary menagerie of fantastical and unreal beasts featuring hundreds of illustrations, from griffins to dog-men, mermaids, dragons, unicorns, and yetis. Fire-breathing dragons, beautiful mermaids, majestic unicorns, terrifying three-headed dogs—these fantastic creatures have long excited our imagination. Medieval authors placed them in the borders of manuscripts as markers of the boundaries of our understanding. Tales from around the world place these beasts in deserts, deep woods, remote islands, ocean depths, and alternate universes—just out of our reach. And in the sections on the apocalypse in the Bible, they proliferate as the end of time approaches, with horses with heads like lions, dragons, and serpents signaling the destruction of the world. Legends tell us that imaginary animals belong to a primordial time, before everything in the world had names, categories, and conceptual frameworks. In this book, Boria Sax digs into the stories of these fabulous beasts. He shows how, despite their liminal role, imaginary animals like griffins, dog-men, yetis, and more are socially constructed creatures, created through the same complex play of sensuality and imagination as real ones. Tracing the history of imaginary animals from Paleolithic art to their roles in stories such as Harry Potter and even the advent of robotic pets, he reveals that these extraordinary figures help us psychologically—as monsters, they give form to our amorphous fears, while as creatures of wonder, they embody our hopes. Their greatest service, Sax concludes, is to continually challenge our imaginations, directing us beyond the limitations of conventional beliefs and expectations. Featuring over 230 illustrations of a veritable menagerie of fantastical and unreal beasts, Imaginary Animals is a feast for the eyes and the imagination.

Book Description
A new edition of the who's who of over 1,400 fictional characters whose names are sometimes so familiar it's difficult to remember they're imaginary. Included in the biographical parade is Ben Casey, Casper, and Fitzwilliam Darcy, a compendium of high, low, and no brow at all, each exactly recorded with a snippet of biographical anecdote. The reference is as equally useful for scholarly work as it is for killing time in aimless pursuits of information. Distributed by Ashgate. Annotation copyright by Book News, Inc., Portland, OR

Book Description
"A collection of flash fiction that feels seemingly arbitrary with an ache of human longing for connection peppered in. . . . These bizarre but beautiful stories transport you elsewhere with no intention of bringing you back." —Ashleah Gonzales, W magazine In this collection of compact fictions, Nicolette Polek transports us to a gently unsettling realm inhabited by disheveled landlords, a fugitive bride, a seamstress who forgets what people look like, and two rival falconers from neighboring towns. They find themselves in bathhouses, sports bars, grocery stores, and forests in search of exits, pink tennis balls, licorice, and independence. Yet all of her beautifully strange characters are possessed by a familiar and human longing for connection: to their homes, families, God, and themselves.

Book Description
Zack and Jasmine never dated, but no one else knows that. That story started in college, because she was being a good friend, and he needed help with something. The friendship and affection that followed were very real, but the lie kept causing trouble. Years later, after a falling out and real relationships with other people, the lie resurfaces to bother Jasmine one more time—when Zack's exes ask her to stop him from marrying someone they think is totally wrong for him. She's the only one who can help him, they say, because she's his best friend. They also believe that Zack loved Jasmine the most—and maybe still does. (This is a revised and expanded edition of My Imaginary Ex, the first book in the Chic Manila series. All books in the series can be read as standalones.)

Book Description
How can we understand the infinite variety of cities? Darran Anderson seems to exhaust all possibilities in this work of creative nonfiction. Drawing inspiration from Marco Polo and Italo Calvino, Anderson shows that we have much to learn about ourselves by looking not only at the cities we have built, but also at the cities we have imagined. Anderson draws on literature (Gustav Meyrink, Franz Kafka, Jaroslav Hasek, and James Joyce), but he also looks at architectural writings and works by the likes of Bruno Taut and Walter Gropius, Medieval travel memoirs from the Middle East, mid-twentieth-century comic books, Star Trek, mythical lands such as Cockaigne, and the works of Claude Debussy. Anderson sees the visionary architecture dreamed up by architects, artists, philosophers, writers, and citizens as wedded to the egalitarian sense that cities are for everyone. He proves that we must not be locked into the structures that exclude ordinary citizens--that cities evolve and that we can have input. As he says: "If a city can be imagined into being, it can be re-imagined as well.”

Book Description
Control of the Imaginary was first published in 1989. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. In Control of the Imaginary Luiz Costa Lima explains how the distinction between truth and fiction emerged at the beginning of modern times and why, upon its emergence, fiction fell under suspicion. Costa Lima not only describes the continuous relationship between Western notions of reason and subjectivity over a broad time-frame—the Renaissance to the first decade of the twentieth century—but he uses this occasion to reexamine the literary traditions of France, Italy, Spain, Portugal, England, and Germany. The book reconstructs the dominant frames in the European tradition between the Middle Ages and the nineteenth century from the perspective of a Latin American who sees the culture of his native Brazil haunted by unresolved questions from the Northern Hemisphere. Costa Lima manages to synthesize positions from philosophy, anthropology, sociology, psychology, linguistics, and history without separating the theoretical discussion from his historical reconstructions. The first chapter situates the problem and grounds the emergent distinction between truth and fiction in a very close analysis of one of the first European historians, Fernao Lopes, who sets the tone for the condemnation of fiction in the name of the truth of history and the potential for individual interpretation. Costa Lima pursues these notions through the aesthetic debates of the seventeenth and eighteenth centuries to the writings of the French historian Michelet. He also devotes an illuminating chapter to the invention of the strictures imposed on fiction.
