In his bestselling The Moral Animal, Robert Wright applied the principles of evolutionary biology to the study of the human mind. Now Wright attempts something even more ambitious: explaining the direction of evolution and human history–and discerning where history will lead us next. In Nonzero: The Logic of Human Destiny, Wright asserts that, ever since the primordial ooze, life has followed a basic pattern. Organisms and human societies alike have grown more complex by mastering the challenges of internal cooperation. Wright's narrative ranges from fossilized bacteria to vampire bats, from stone-age villages to the World Trade Organization, uncovering such surprises as the benefits of barbarian hordes and the useful stability of feudalism. Here is history endowed with moral significance–a way of looking at our biological and cultural evolution that suggests, refreshingly, that human morality has improved over time, and that our instinct to discover meaning may itself serve a higher purpose. Insightful, witty, profound, Nonzero offers breathtaking implications for what we believe and how we adapt to technology's ongoing transformation of the world.

Learn about the driving forces of your destiny. As human beings, we constantly question the concept of fate. Does it exist? Is it intentional? Is it responsible for the directions of our lives? Fortunately for us, acclaimed scholar and thinker Robert Wright has pondered these same questions and embarked on an ambitious quest to answer life’s seemingly unanswerable questions. Nonzero (2001) is the fruit of his labor. Positing that human morality has evolved for the better and that we have learned to shape our own destinies, Nonzero is a holistic look back through history.

In a book sure to stir argument for years to come, Robert Wright challen+ges the conventional view that biological evolution and human history are aimless. Ingeniously employing game theory - the logic of 'zero-sum' and 'non-zero-sum' games - Wright isolates the impetus behind life's basic direction: the impetus that, via biological evolution, created complex, intelligent animals, and then via cultural evolution, pushed the human species towards deeper and vaster social complexity. In this view, the coming of today's independent global society was 'in the cards' - not quite inevitable, but, as Wright puts it, 'so probable as to inspire wonder'. In a narrative of breathtaking scope and erudition, yet pungent wit, Wright takes on some of the past century's most prominent thinkers, including Isaiah Berlin, Karl Popper, Stephen Jay Gould, and Richard Dawkins. Wright argues that a coolly specific appraisal of humanity's three-billion-year past can give new spiritual meaning to the present and even offer political guidance for the future. This book will change the way people think about the human prospect.

This book gives an overview of research on graphs associated with commutative rings. The study of the connections between algebraic structures and certain graphs, especially finite groups and their Cayley graphs, is a classical subject which has attracted a lot of interest. More recently, attention has focused on graphs constructed from commutative rings, a field of study which has generated an extensive amount of research over the last three decades. The aim of this text is to consolidate this large body of work into a single volume, with the intention of encouraging interdisciplinary research between algebraists and graph theorists, using the tools of one subject to solve the problems of the other. The topics covered include the graphical and topological properties of zero-divisor graphs, total graphs and their transformations, and other graphs associated with rings. The book will be of interest to researchers in commutative algebra and graph theory and anyone interested in learning about the connections between these two subjects.

This is the first monograph devoted to clean ring and matrix theory. It aims to study a theory of expressing an element in a ring as the sum of some special ones, such as idempotents, units, nilpotents, tripotents, involutions, etc. A matrix over such rings is thereby expressed as the sum of some special matrices. Also another topics on the behaviors of topological properties and *-properties of such rings are investigated.The book is based on the results of various published papers, particularly, by the authors'. It is accessible for students familiar with general abstract algebra, while the topics are interesting for researchers in the field of ring, matrix and operator theory.

A n x n zero-nonzero pattern [special character omitted] is spectrally arbitrary over a field F if for each monic, degree n polynomial p (t) in F [t], there exists a matrix A over F with zero-nonzero pattern [special character omitted] such that the characteristic polynomial of F is p(t).

Did you know that any straight-line drawing on paper can be folded so that the complete drawing can be cut out with one straight scissors cut? That there is a planar linkage that can trace out any algebraic curve, or even 'sign your name'? Or that a 'Latin cross' unfolding of a cube can be refolded to 23 different convex polyhedra? Over the past decade, there has been a surge of interest in such problems, with applications ranging from robotics to protein folding. With an emphasis on algorithmic or computational aspects, this treatment gives hundreds of results and over 60 unsolved 'open problems' to inspire further research. The authors cover one-dimensional (1D) objects (linkages), 2D objects (paper), and 3D objects (polyhedra). Aimed at advanced undergraduate and graduate students in mathematics or computer science, this lavishly illustrated book will fascinate a broad audience, from school students to researchers.
