The Planiverse

A classic book about life in a two-dimensional universe, written by a well-known author. Now brought back into print in this revised and updated edition, the book is written within the great tradition of Abbott's Flatland, and Hinton's famous Sphereland. Accessible, imaginative, and clever, it will appeal to a wide array of readers, from serious mathematicians and computer scientists, to science fiction fans.

The concept of world and the practice of world creation have been with us since antiquity, but they are now achieving unequalled prominence. In this timely anthology of subcreation studies, an international roster of contributors come together to examine the rise and structure of worlds, the practice of world-building, and the audience's reception of imaginary worlds. Including essays written by world-builders A.K. Dewdney and Alex McDowell and offering critical analyses of popular worlds such as those of Oz, The Lord of the Rings, Star Trek, Star Wars, Battlestar Galactica, and Minecraft, Revisiting Imaginary Worlds provides readers with a broad and interdisciplinary overview of the issues and concepts involved in imaginary worlds across media platforms.

Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one-before Gardner-had written about mathematics like this. They continue to be a marvel. This is the original 1997 edition and contains columns published from 1980-1986.

The study of narrative—the object of the rapidly growing discipline of narratology—has been traditionally concerned with the fictional narratives of literature, such as novels or short stories. But narrative is a transdisciplinary and transmedial concept whose manifestations encompass both the fictional and the factual. In this volume, which provides a companion piece to Tobias Klauk and Tilmann Köppe’s Fiktionalität: Ein interdisziplinäres Handbuch, the use of narrative to convey true and reliable information is systematically explored across media, cultures and disciplines, as well as in its narratological, stylistic, philosophical, and rhetorical dimensions. At a time when the notion of truth has come under attack, it is imperative to reaffirm the commitment to facts of certain types of narrative, and to examine critically the foundations of this commitment. But because it takes a background for a figure to emerge clearly, this book will also explore nonfactual types of narratives, thereby providing insights into the nature of narrative fiction that could not be reached from the narrowly literary perspective of early narratology.

This book will appeal to at least three groups of readers: prospective high school teachers, liberal arts students, and parents whose children are studying high school or college math. It is modern in its selection of topics, and in the learning models used by the authors. The book covers some exciting but non-traditional topics from the subject area of geometry. It is also intended for undergraduates and tries to engage their interest in mathematics. Many innovative pedagogical modes are used throughout.

This volume collects many of the columns Keith Devlin wrote for The Guardian.
