Genre-defying fiction that accelerates "cross-cultural dialogue" into a kaleidoscopic rush of sensory estrangements, fairy tales, and alien encounters. "There's really no difference between us and them, so we're told…." Based on the author's experiences of living as an American in Iran, Kristen Alvanson's XYZT is a wildly imaginative dramatization of the idea of a "dialogue of civilizations" and its potentially outlandish ramifications. As part of an advanced technological test program, volunteers are shuttled back and forth between the US and Iran, hidden from the watchful eyes of immigration police and state bureaucracies. Each is given a single opportunity to be received by a local host and to have a brief authentic experience of what it means to live as “them” before being transported back home. But far from heralding the bliss of mutual recognition, the experiment unleashes a series of displacements so disorienting that the fabric of reality begins to fray. Ordinary people become entangled in extraordinary situations, and everyday life bleeds into mythological encounters, alternate universes and dark psychedelic journeys in alien lands where the real and the imaginary are indistinguishable. A treasury of tales told from multiple perspectives and in a multiplicity of styles, XYZT is an audacious cross-genre experiment, a firsthand memoir of what it means to see what "they" see, and a science-fictional, nonstandard engagement with anthropology in which cross-cultural encounters take on all the unpredictable features of a contemporary fairy tale.

Wallis's book on discrete mathematics is a resource for an introductory course in a subject fundamental to both mathematics and computer science, a course that is expected not only to cover certain specific topics but also to introduce students to important modes of thought specific to each discipline . . . Lower-division undergraduates through graduate students. —Choice reviews (Review of the First Edition) Very appropriately entitled as a 'beginner's guide', this textbook presents itself as the first exposure to discrete mathematics and rigorous proof for the mathematics or computer science student. —Zentralblatt Math (Review of the First Edition) This second edition of A Beginner’s Guide to Discrete Mathematics presents a detailed guide to discrete mathematics and its relationship to other mathematical subjects including set theory, probability, cryptography, graph theory, and number theory. This textbook has a distinctly applied orientation and explores a variety of applications. Key Features of the second edition: * Includes a new chapter on the theory of voting as well as numerous new examples and exercises throughout the book * Introduces functions, vectors, matrices, number systems, scientific notations, and the representation of numbers in computers * Provides examples which then lead into easy practice problems throughout the text and full exercise at the end of each chapter * Full solutions for practice problems are provided at the end of the book This text is intended for undergraduates in mathematics and computer science, however, featured special topics and applications may also interest graduate students.
