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.

Now available in paperback! Where does the road to reality lie? This fundamental question is addressed in this collection of essays by physicists and philosophers, inspired by the original ideas of Sir Roger Penrose, the English mathematical physicist and philosopher of science. The topics range from black holes and quantum information to the very nature of mathematical cognition itself. [Subject: Philosophy, Physics, Mathematics, Cosmology]~

Der Weg zur Wirklichkeit ist eine Kurzübersetzung des Penrose-Klassikers "The Road to Reality", die aus dem Monumentalwerk für Physik- und Mathematikexperten die allgemeinverständlichen Kapitel für interessierte Laien lesbar macht. Wer ein Faible für die Grundfragen der Wissenschaft, einen Blick für Geometrie, einen Sinn für Zahlen und Neugier für kosmologische Theorien hat, findet in diesem klar und kompetent geschriebenen Buch überraschende und provozierende Ideen. Schulmathematik wie die Bruchrechnung oder der berühmte Pythagorassatz lassen sich auf dem Weg zur Wirklichkeit völlig neu entdecken - im Spannungsfeld zwischen platonischer Mathematik, physikalischer Welt und menschlichem Bewusstsein.

Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united into a single quantum theory of gravity? Can quantum and cosmos ever be combined? In The Nature of Space and Time, two of the world’s most famous physicists—Stephen Hawking (A Brief History of Time) and Roger Penrose (The Road to Reality)—debate these questions. The authors outline how their positions have further diverged on a number of key issues, including the spatial geometry of the universe, inflationary versus cyclic theories of the cosmos, and the black-hole information-loss paradox. Though much progress has been made, Hawking and Penrose stress that physicists still have further to go in their quest for a quantum theory of gravity.

In diesem Buch verteidigt Roger Penrose seine These, daß Bewußtsein auf quantentheoretischer Basis erklärt werden könnte - wobei er sich der Kritik des theoretischen Physikers und Kosmologen Stephen Hawking, der Philosophin Nancy Cartwright und des Philosophen Abner Shimony stellt. Hawking, ehemaliger Student, Freund und Kollege von Penrose, wendet sich gegen eine platonistische Sicht, der zufolge mathematische Objekte in einer Ideenwelt existieren. Als Positivist glaubt Hawking, daß mathematische Modelle Konstruktionen sind, die sich an physikalischen Beobachtungen als richtig oder falsch erweisen. Abner Shimony wendet ein, daß eine philosophische Begründung der Phänomene nur möglich ist, wenn man sich auf eine philosophische Ontologie einigt. Wie kann ein Physikalismus, der allein quantenmechanische Phänomene und ihre mathematischen Beschreibungen zuläßt, ein nichtphysikalisches Problem wie Bewußtsein erklären? Nancy Cartwright schließlich fragt, mit welcher Berechtigung die Physik den anderen Wissenschaften bei der Erklärung des Bewußtseins vorzuziehen sei. Warum nicht Bewußtsein mit biologischen Gesetzen begründen? All diese Fragen lassen Penrose nicht an seinem Konzept zweifeln, den Schlüssel für die Unberechenbarkeit vieler Bewußtseinsprozesse in einer künftigen Theorie zu vermuten, die Quantenphysik und Gravitation vereinigen soll.

Cycles of Time

An Extraordinary New View of the Universe

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. Original and compelling, Cycles of Time offers new answers to the ultimate questions of life.

Fashion, Faith, and Fantasy in the New Physics of the Universe

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.

For many decades, the proponents of `artificial intelligence' have maintained that computers will soon be able to do everything that a human can do. In his bestselling work of popular science, Sir Roger Penrose takes us on a fascinating tour through the basic principles of physics, cosmology, mathematics, and philosophy to show that human thinking can never be emulated by a machine. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

Robert Geroch builds on Einstein's work with commentary that addresses the ideas at the heart of the theory, bringing a modern understanding of relativity to the text. He elucidates how special relativity is a reconciliation of the contradictions between the nature of light and the principle of relativity; he expands on Einstein's treatment of the geometry of space-time and the fundamental notion of an "event"; he explains in detail, but without technical language, the equivalence of inertial and gravitational mass, a cornerstone of general relativity.
