The Road to Reality is the most important and ambitious work of science for a generation. It provides nothing less than a comprehensive account of the physical universe and the essentials of its underlying mathematical theory. It assumes no particular specialist knowledge on the part of the reader, so that, for example, the early chapters give us the vital mathematical background to the physical theories explored later in the book. Roger Penrose's purpose is to describe as clearly as possible our present understanding of the universe and to convey a feeling for its deep beauty and philosophical implications, as well as its intricate logical interconnections. The Road to Reality is rarely less than challenging, but the book is leavened by vivid descriptive passages, as well as hundreds of hand-drawn diagrams. In a single work of colossal scope one of the world's greatest scientists has given us a complete and unrivalled guide to the glories of the universe that we all inhabit.

What can fashionable ideas, blind faith, or pure fantasy possibly have to do with the scientific quest to understand the universe? Surely, theoretical physicists are immune to mere trends, dogmatic beliefs, or flights of fancy? In fact, acclaimed physicist and bestselling author Roger Penrose argues that researchers working at the extreme frontiers of physics are just as susceptible to these forces as anyone else. In this provocative book, he argues that fashion, faith, and fantasy, while sometimes productive and even essential in physics, may be leading today's researchers astray in three of the field's most important areas—string theory, quantum mechanics, and cosmology. Arguing that string theory has veered away from physical reality by positing six extra hidden dimensions, Penrose cautions that the fashionable nature of a theory can cloud our judgment of its plausibility. In the case of quantum mechanics, its stunning success in explaining the atomic universe has led to an uncritical faith that it must also apply to reasonably massive objects, and Penrose responds by suggesting possible changes in quantum theory. Turning to cosmology, he argues that most of the current fantastical ideas about the origins of the universe cannot be true, but that an even wilder reality may lie behind them. Finally, Penrose describes how fashion, faith, and fantasy have ironically also shaped his own work, from twistor theory, a possible alternative to string theory that is beginning to acquire a fashionable status, to "conformal cyclic cosmology," an idea so fantastic that it could be called "conformal crazy cosmology." The result is an important critique of some of the most significant developments in physics today from one of its most eminent figures.

This book discusses and summarizes the revived interest in reality issues (ontology) within accounting, economics, and the information sciences, with a view to informing scholars from these different disciplines about each other’s endeavours in ontological research. Even more importantly, the book aims at familiarizing scholars from various disciplines with an evolutionary approach for examining questions about reality in the social sciences. The book is based on a partly pluralistic approach that assures unity in diversity. Unity, because all existence arises from physical reality; diversity, because emergent properties create biological and social realities that cannot be reduced to physical phenomena. Hence, the book recognizes not only concrete but also abstract entities. It shows, however, that the actualization of these abstract entities requires objectification and concrete manifestation. This pluralistic approach is central to this book. It also is a challenge to those who reject abstract entities as socially real, as well as to those who defend a non-realist position. The major task of this book is to explore proposals towards a uniform ontological basis. This uniform and universal presentation extends beyond traditional ontology (asking ‘what is real?’) to such questions as ‘on which reality level is something real?’ and ‘in which (temporal and modal) way is it real?’. Such an extended analysis) is relevant to accountants, economists, information scientists, other social scientists as well as philosophers.

Two and a half years after the devastation of Hurricanes Katrina and Rita, New Orleans and south Louisiana continue to struggle in an unsettled gumbo of environmental, social, and rebuilding chaos. Citizens await the fruition of four successive recovery and reconstruction planning processes and the realization of essential infrastructure repairs. Repopulation in Orleans Parish has slowed considerably; the parish remains at best two-thirds of its former size; thousands of former residents who wish to return face barriers of many kinds. Heroic efforts at rebuilding have occurred through the efforts of individual neighborhood associations and voluntary associations who have attempted to address serious losses in affordable housing and health care services. Walking to New Orleans traces how a dominant but paradoxical model of the relation between the human and natural worlds in Western culture has informed many environmental and engineering dilemmas and has contributed to the history of social inequities and injustice that anteceded the disasters of the hurricanes and subsequent flooding. It proposes a model for collaborative recovery that links principles of ethics and engineering, in which citizens become active, ongoing participants in the process of the reconstruction and redesign of their unique locus of habitation. Equally important, it gives voice to the citizens and associations who are desperately working to rebuild their homes and lives both in urban New Orleans and in the villages of coastal Louisiana.

Synthesizing thirty years of research, psychologist and science historian, Michael Shermer upends the traditional thinking about how humans form beliefs about the world. Simply put, beliefs come first and explanations for beliefs follow. The brain, Shermer argues, is a belief engine. Using sensory data that flow in through the senses, the brain naturally looks for and finds patterns - and then infuses those patterns with meaning, forming beliefs. Once beliefs are formed, our brains subconsciously seek out confirmatory evidence in support of those beliefs, which accelerates the process of reinforcing them, and round and round the process goes in a positive-feedback loop. In The Believing Brain, Shermer provides countless real-world examples of how this process operates, from politics, economics, and religion to conspiracy theories, the supernatural, and the paranormal. Ultimately, he demonstrates why science is the best tool ever devised to determine whether or not our belief matches reality.
