A Category 4 hurricane, with winds of up to 155 miles per hour, tears roofs off buildings, smashes windows and doors, and can send floodwaters up to the second floor. Evacuation is suggested for up to six miles inland. Hurricane Katrina was a Category 4 when she made landfall. Hurricane Simone is a Category 7—the biggest, strongest storm in recorded history. When she hits New York City, skyscrapers will fall. Subways and tunnels will flood. Lower Manhattan and much of Queens and Brooklyn will disappear under more than thirty feet of water. All along the Eastern Seaboard, towns and cities are being evacuated as wind-driven rain lashes the coast and storm surges crash through seawalls. Roads are packed with fleeing motorists whose cars are jammed with every personal possession that can be crammed in, plus family members, friends, and beloved pets. A huge natural disaster is brewing in the Atlantic. Except that Simone isn't natural. She's the product of rogue weather science being wielded by billionaire Carter Thompson as part of a personal vendetta against US President Winslow Benson. Once Carter wanted to bring rain to the desert and feed the starving peoples of the planet. Now he wants to show Benson—and the rest of the world—just how powerful wind and water can be. If technology created Simone, perhaps technology can stop her. It's up to Kate Sherman, once a member of Carter's weather team; and Jake Baxter, a weatherman for the CIA, to try, using a secret US Navy weapon. The catch? It has to be deployed inside the hurricane. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Finally, back in print! Edward Gorey's CATEGORY was first published by Gotham Book Mart in 1974. The English language edition has been out of print for decades. One of Gorey's most beloved books, CATEGORY collects a series of fifty cat vignettes, originally created by the artist as accompaniments to a limited edition of his book Amphigorey. Gorey once said, "I can't conceive of a life without cats." Now Gorey fans and cat lovers alike won't have to conceive of a world without CATEGOREY. Edward Gorey (1925-2000) may be best known for his mildly unsettling illustrated tales and cautionary alphabets—The Deranged Cousins, The Gashlycrumb Tinies, and The Doubtful Guest, among many others. He was also a playwright, an award-winning set and costume designer, and the creator of the animated introductions to the PBS series Mystery!

The concept that people have of themselves as a 'person' is one of the most intimate notions that they hold. Yet the way in which the category of the person is conceived varies over time and space. In this volume, anthropologists, philosophers, and historians examine the notion of the person in different cultures, past and present. Taking as their starting point a lecture on the person as a category of the human mind, given by Marcel Mauss in 1938, the contributors critically assess Mauss's speculation that notions of the person, rather than being primarily philosophical or psychological, have a complex social and ideological origin. Discussing societies ranging from ancient Greece, India, and China to modern Africa and Papua New Guinea, they provide fascinating descriptions of how these different cultures define the person. But they also raise deeper theoretical issues: What is universally constant and what is culturally variable in people's thinking about the person? How can these variations be explained? Has there been a general progressive development toward the modern Western view of the person? What is distinctive about this? How do one's notions of the person inform one's ability to comprehend alternative formulations? These questions are of compelling interest for a wide range of anthropologists, philosophers, historians, psychologists, sociologists, orientalists, and classicists. The book will appeal to any reader concerned with understanding one of the most fundamental aspects of human existence.

This textbook provides an introduction to elementary category theory, with the aim of making what can be a confusing and sometimes overwhelming subject more accessible. In writing about this challenging subject, the author has brought to bear all of the experience he has gained in authoring over 30 books in university-level mathematics. The goal of this book is to present the five major ideas of category theory: categories, functors, natural transformations, universality, and adjoints in as friendly and relaxed a manner as possible while at the same time not sacrificing rigor. These topics are developed in a straightforward, step-by-step manner and are accompanied by numerous examples and exercises, most of which are drawn from abstract algebra. The first chapter of the book introduces the definitions of category and functor and discusses diagrams,duality, initial and terminal objects, special types of morphisms, and some special types of categories,particularly comma categories and hom-set categories. Chapter 2 is devoted to functors and naturaltransformations, concluding with Yoneda's lemma. Chapter 3 presents the concept of universality and Chapter 4 continues this discussion by exploring cones, limits, and the most common categorical constructions – products, equalizers, pullbacks and exponentials (along with their dual constructions). The chapter concludes with a theorem on the existence of limits. Finally, Chapter 5 covers adjoints and adjunctions. Graduate and advanced undergraduates students in mathematics, computer science, physics, or related fields who need to know or use category theory in their work will find An Introduction to Category Theory to be a concise and accessible resource. It will be particularly useful for those looking for a more elementary treatment of the topic before tackling more advanced texts.

The Handbook of Categorical Algebra is designed to give, in three volumes, a detailed account of what should be known by everybody working in, or using, category theory. As such it will be a unique reference. The volumes are written in sequence, with the first being essentially self-contained, and are accessible to graduate students with a good background in mathematics. In particular, Volume 1, which is devoted to general concepts, can be used for advanced undergraduate courses on category theory.

In Aristotle on the Category of Relation, Pamela Hood challenges the view that Aristotle's conception of relation is so divergent from our own that it does not count as a theory of relation at all. This book presents compelling evidence that Aristotle's theory of relation is more robust than originally suspected.

As category theory approaches its first half-century, it continues to grow, finding new applications in areas that would have seemed inconceivable a generation ago, as well as in more traditional areas. The language, ideas, and techniques of category theory are well suited to discovering unifying structures in apparently different contexts. Representing this diversity of the field, this book contains the proceedings of an international conference on category theory. The subjects covered here range from topology and geometry to logic and theoretical computer science, from homotopy to braids and conformal field theory. Although generally aimed at experts in the various fields represented, the book will also provide an excellent opportunity for nonexperts to get a feel for the diversity of current applications of category theory.

This book, first published in 2000, develops aspects of category theory fundamental to the study of algebraic K-theory. Ring and module theory illustrates category theory which provides insight into more advanced topics in module theory. Starting with categories in general, the text then examines categories of K-theory. This leads to the study of tensor products and the Morita theory. The categorical approach to localizations and completions of modules is formulated in terms of direct and inverse limits, prompting a discussion of localization of categories in general. Finally, local-global techniques which supply information about modules from their localizations and completions and underlie some interesting applications of K-theory to number theory and geometry are considered. Many useful exercises, concrete illustrations of abstract concepts placed in their historical settings and an extensive list of references are included. This book will help all who wish to work in K-theory to master its prerequisites.
