Fashion Faith And Fantasy In The New Physics Of The Universe


One of the world's leading physicists questions some of the most fashionable ideas in physics today, including string theory 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.

What Is Life


"What Is Life?" is Nobel laureate Erwin Schrödinger's exploration of the question which lies at the heart of biology. His essay, "Mind and Matter," investigates what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. "Autobiographical Sketches" offers a fascinating fragmentary account of his life as a background to his scientific writings.

Cycles Of Time


What came before the Big Bang? How did the universe begin and must it inevitably end? In this remarkable book Roger Penrose brilliantly illuminates some of the deepest mysteries of the universe. Cycles of Time contains a penetrating analysis of the second law of thermodynamics - according to which the 'randomness' of our world is continually increasing - and a thorough examination of the light-cone geometry of space-time. It combines these two central themes to show how the expected ultimate fate of our accelerating, expanding universe can actually be reinterpreted as the 'big bang' of a new one. Presenting various standard and non-standard cosmological models, discussing black holes in depth as well as taking in the role of the cosmic microwave background along the way, Roger Penrose argues that the Big Bang was not actually the beginning of everything - nor will it signal the end. ‘Science needs more people like Penrose, willing and able to point out the flaws in fashionable models from a position of authority, and to signpost alternative roads to follow’ Independent

Egods


What is the relationship between religion and multi-player online roleplaying games? Are such games simply a secular distraction from traditional religious practices, or do they in fact offer a different route to the sacred? In eGods, a leading scholar in the study of virtual gameworlds takes an in-depth look at the fantasy religions of 41 games and arrives at some surprising conclusions. William Sims Bainbridge investigates all aspects of the gameworlds' religious dimensions: the focus on sacred spaces; the prevalence of magic; the fostering of a tribal morality by both religion and rules programmed into the game; the rise of cults and belief systems within the gameworlds (and how this relates to cults in the real world); the predominance of polytheism; and, of course, how gameworld religions depict death. As avatars are multiple and immortal, death is merely a minor setback in most games. Nevertheless, much of the action in some gameworlds centers on the issue of mortality and the problematic nature of resurrection. Examining EverQuest II, Lord of the Rings Online, Rift, World of Warcraft, Star Wars: The Old Republic, and many others, Bainbridge contends that gameworlds offer a new perspective on the human quest, one that combines the arts, simulates many aspects of real life, and provides meaningful narratives about achieving goals by overcoming obstacles. Indeed, Bainbridge suggests that such games take us back to those ancient nights around the fire, when shadows flickered and it was easy to imagine the monsters conjured by the storyteller lurking in the forest. Arguing that gameworlds reintroduce a curvilinear model of early religion, where today as in ancient times faith is inseparable from fantasy, eGods shows how the newest secular technology returns us to the very origins of religion so that we might "arrive where we started and know the place for the first time."

Not Even Wrong


Not Even Wrong is a fascinating exploration of our attempts to come to grips with perhaps the most intellectually demanding puzzle of all: how does the universe work at its most fundamnetal level? The book begins with an historical survey of the experimental and theoretical developments that led to the creation of the phenomenally successful 'Standard Model' of particle physics around 1975. Despite its successes, the Standard Model does not answer all the key questions and physicists continuing search for answers led to the development of superstring theory. However, after twenty years, superstring theory has failed to advance beyond the Standard Model. The absence of experimental evidence is at the core of this controversial situation which means that it is impossible to prove that superstring theory is either right or wrong. To date, only the arguments of the theory's advocates have received much publicity. Not Even Wrong provides readers with another side of the story.

Quantum Theory Groups And Representations


This text systematically presents the basics of quantum mechanics, emphasizing the role of Lie groups, Lie algebras, and their unitary representations. The mathematical structure of the subject is brought to the fore, intentionally avoiding significant overlap with material from standard physics courses in quantum mechanics and quantum field theory. The level of presentation is attractive to mathematics students looking to learn about both quantum mechanics and representation theory, while also appealing to physics students who would like to know more about the mathematics underlying the subject. This text showcases the numerous differences between typical mathematical and physical treatments of the subject. The latter portions of the book focus on central mathematical objects that occur in the Standard Model of particle physics, underlining the deep and intimate connections between mathematics and the physical world. While an elementary physics course of some kind would be helpful to the reader, no specific background in physics is assumed, making this book accessible to students with a grounding in multivariable calculus and linear algebra. Many exercises are provided to develop the reader's understanding of and facility in quantum-theoretical concepts and calculations.
