New Releases by Roger Penrose

Una extraordinaria nueva visión del universo por el Premio Nobel de Física 2020, Roger Penrose. La revolucionaria y exitosa obra de Roger Penrose El camino a la realidad presentaba una guía completa y comprensible de las leyes que rigen el universo desde nuestro conocimiento actual. En Ciclos del tiempo, su libro más ambicioso, Penrose va mucho más allá: desarrolla una visión inédita de la cosmología y propone una respuesta inesperada a la pregunta "¿Qué pasó antes del Big Bang?". Las dos ideas clave que hay detrás de esta nueva visión son un penetrante análisis de la Segunda Ley de la termodinámica (que establece el principio de la entropía) y el estudio de la geometría de conos de luz del espacio-tiempo. Penrose logra combinar estos dos temas para demostrar que el destino último de nuestro universo en expansión y aceleración puede ser visto como el "big bang" de uno nuevo. Por el camino, nos explica muchos otros ingredientes básicos de esta idea y comenta varios modelos cosmológicos, tanto ortodoxos como heterodoxos, así como el papel fundamental y ubicuo de la radiación cósmica de microondas. Otra parte crucial de su exposición es la relativa a los inmensos agujeros negros detectados en los centros de las galaxias, y su eventual desaparición a través del misterioso proceso de evaporación de Hawking. Una obra fundamental para todos los amantes de la ciencia Reseñas: «El camino a la realidad es una innovación radical en la divulgación científica. En primer lugar porque desafía de manera flagrante y sistemática la ley de Hawking: "Cada ecuación que introduces en un libro reduce las ventas a la mitad"... El camino a la realidad es, simple y llanamente, una invitación a todo el mundo que quiera subirse al carro de la ciencia contemporánea.» Javier Sampedro, Babelia «El optimismo de Penrose es contagioso. Lo cierto es que a quien se atreve con este libro se le exige un enorme esfuerzo que tiene una incomparable recompensa: lo que aquí se cuenta es la aproximación más perfecta que se tiene de la realidad. El aparato construido para llevar a cabo esta proeza es uno de los productos más sublimes que puede aportar la mente humana como tarjeta de visita... la satisfacción intelectual está garantizada.» Leer «Aquellos interesados en los secretos del universo y su inquietante pasado, presente y futuro no pueden perderse este fascinante relato del gran divulgador de la astrofísica contemporánea.» La Razón

Professor Sir Roger Penrose is one of the truly original thinkers of our time. He has made several remarkable contributions to science, from quantum physics and theories of human consciousness to relativity theory and observations on the structure of the universe. Unusually for a scientist, some of his ideas have crossed over into the public arena. Now his work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes.

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.

From two of the world''s great physicists—Stephen Hawking and Nobel laureate Roger Penrose—a lively debate about the nature of space and time 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.

The work of the contemporary sculptor Antony Gormley, articulates a distinctive and arresting vision. By insisting on the body as a place and using his own as his primary vehicle, Gormley has, over 20 years, focused on the body as a site of transformation. This publication brings together three of his works and includes an essay which places his sculptures in the wider context of British sculpture, and contains references to the anthropological concepts that underpin his work.

Présentation de tous les outils mathématiques dont se sert la science dans son élucidation du monde. De la géométrie classique à la théorie quantique des champs en passant par la théorie des twisters, l''ouvrage explique tout ce dont la physique moderne ne peut se passer : les nombres réels et complexes, les logarithmes, les exponentielles, etc.

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.

Einstein aimait à répéter que le plus incompréhensible dans l''univers est bien qu''il soit compréhensible. La chose est-elle si sûre ? La théorie quantique des champs et la théorie de la relativité générale d''Einstein sont à l''heure actuelle les deux théories les mieux vérifiées en physique : pourra-t-on les unifier en une théorie quantique de la gravité ? Celle-ci expliquerait toutes les singularités - les premières secondes de l''univers comme la physique de ces objets énigmatiques que sont les trous noirs. Notre intelligence de l''univers ferait alors un pas de géant. Mais quantique et cosmos peuvent-ils même être combinés ? Sur les questions cruciales de l''espace et du temps, qui manifestent les insuffisances des théories, deux des plus célèbres physiciens - Stephen Hawking et Roger Penrose - s''opposent dans un débat sans concession. En écho aux fameux débats qui opposèrent Bohr et Einstein sur les bizarres implications de la théorie quantique, cet ouvrage à deux voix donne à ses lecteurs l''occasion unique d''assister, aux premières loges, à l''élaboration, par la physique du XXIe siècle des grandes réponses aux énigmes sur lesquelles vient encore buter notre compréhension du cosmos.

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.

Este volume fornece uma introdução acessível e iluminadora à posição de Penrose sobre as perspectivas da física teórica para o século XXI. Ele resume e atualiza as polêmicas idéias apresentadas em seus livros anteriores, A mente nova do rei e Shadows of the mind, e inclui contribuições marcantes de Abner Shimony, Nancy Cartwright e Stephen Hawking. É um livro profundo de uma das mais originais e instigantes mentes da ciência contemporânea.

A 21st-Century Utopia Two of England''s most distinguished thinkers have created a bold and startling vision of a new society escaping the ashes of the old. In the not-so-distant future, Man will have begun to colonize our planetary neighbor, Mars. Entrenched corporate and national interests have footed the bill, but a few visionary people attempt to keep Mars free of the hidebound ideologies that have plagued the Earth and turned it into a polluted wasteland of war and hunger. The colony has barely begun to take root in the Martian soil when all communication with EUPACUS--as the industrialized nations of Earth are known--is cut off completely. Environmental and economic stresses have finally spun out of control, and civilization as we know it has collapsed. With no hope of escape or support from Earth, the Martians must overcome the dire obstacles that face them and forge a new alliance for survival. Led by the brave Tom Jefferies, the colonists struggle to build a new way of living based on the search for knowledge, the improvement of human conditions, and the elimination of the hatreds and delusions that lead to misery in the past. Included in an appendix is the complete text of the Charter for an Independent Mars, written by Dr. Laurence Lustgarten, a renowned expert on international law.

Roger Penrose''s original and provocative ideas about the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind have been the subject of controversy and discussion. These ideas were set forth in his best-selling books The Emperor''s New Mind and Shadows of the Mind. In this book, he summarises and brings up to date his current thinking in these complex areas. He presents a masterful summary of those areas of physics in which he feels there are major unsolved problems. Through this, he introduces radically new concepts which he believes will be fruitful in understanding the workings of the brain and the nature of the human mind. These ideas are then challenged by three distinguished experts from different backgrounds - Abner Shimony and Nancy Cartwright as Philosophers of Science and Stephen Hawking as a Theoretical Physicist and Cosmologist. Finally, Roger Penrose responds to their thought-provoking criticisms. This volume provides an accessible, illuminating and stimulating introduction to Roger Penrose''s vision of theoretical physics for the 21st Century. His enthusiasm, insight and good humour shine through this brilliant account of the problems of modern physics.

El exito obtenido por la Historia del tiempo, de Stephen Hawking, propicio la creacion, en 1991, de esta coleccion de divulgacion cientifica que fue dirigida durante largo tiempo por dos personas de formacion humanistica: de ahi ciertas contaminaciones al inicio de la coleccion. Sin embargo, cuando Jose Manuel Sanchez Ron se hizo cargo de ella, dio un aprobado a la gestion anterior. En esta coleccion, quiza la mas ambiciosa de todas las de divulgacion cientifica que se editan en espanol, se han publicado obras de Stephen Jay Gould, Carl Sagan, lan Stewart, Edward O. Wilson, Antonio Damasio, Luigi Luca Cavalli-Sforza, Ilya Prigogine, John D. Barrow, Rita Levi Montalcini, Richard P. Feynman, Roger Penrose, Steven Weinberg, Rachel Carson, Francisco Garcia Olmedo, Francisco Yndurain o Jose Manuel Sanchez Ron. El autor se enfrenta en este libro a una tarea ambiciosa: llegar a una comprension cientifica de la mente humana, que, en su opinion, no puede reducirse a los esquemas simplistas de quienes sostienen que la mentalidad consciente procede como un ordenador y puede explicarse en teminos de modelos computacionales.
