What does realism about the quantum state imply? What follows when quantum theory is applied without restriction, if need be, to the whole universe? These are the questions which an illustrious team of philosophers and physicists debate in this volume. All the contributors are agreed on realism, and on the need, or the aspiration, for a theory that unites micro- and macroworlds, at least in principle. But the further claim argued by some is that if you allow the Schrödinger equation unrestricted application, supposing the quantum state to be something physically real, then this universe is one of countlessly many others, constantly branching in time, all of which are real. The result is the many worlds theory, also known as the Everett interpretation of quantum mechanics. The contrary claim sees this picture of many worlds as in no sense inherent in quantum mechanics, even when the latter is allowed unrestricted scope and even given that the quantum state itself is something physically real. For this picture of branching worlds fails to make physical sense, let alone common sense, even on its own terms. The status of these worlds, what they are made of, is never adequately explained. Ordinary ideas about time and identity over time become hopelessly compromised. The concept of probability itself is brought into question. This picture of many branching worlds is inchoate, it is a vision, an error. There are realist alternatives to many worlds, some even that preserve the Schrödinger equation unchanged. Twenty specially written essays, accompanied by commentaries and discussions, examine these claims and counterclaims in depth. They focus first on the question of ontology, the existence of worlds (Part 1 and 2), second on the interpretation of probability (Parts 3 and 4), and third on alternatives or additions to many worlds (Parts 5 and 6). The introduction offers a helpful guide to the arguments for the Everett interpretation, particularly as they have been formulated in the last two decades.

A novel interpretation of quantum mechanics, first proposed in brief form by Hugh Everett in 1957, forms the nucleus around which this book has developed. In his interpretation, Dr. Everett denies the existence of a separate classical realm and asserts the propriety of considering a state vector for the whole universe. Because this state vector never collapses, reality as a whole is rigorously deterministic. This reality, which is described jointly by the dynamical variables and the state vector, is not the reality customarily perceived; rather, it is a reality composed of many worlds. By virtue of the temporal development of the dynamical variables, the state vector decomposes naturally into orthogonal vectors, reflecting a continual splitting of the universe into a multitude of mutually unobservable but equally real worlds, in each of which every good measurement has yielded a definite result, and in most of which the familiar statistical quantum laws hold. The volume contains Dr. Everett's short paper from 1957, "'Relative State' Formulation of Quantum Mechanics," and a far longer exposition of his interpretation, entitled "The Theory of the Universal Wave Function," never before published. In addition, other papers by Wheeler, DeWitt, Graham, and Cooper and Van Vechten provide further discussion of the same theme. Together, they constitute virtually the entire world output of scholarly commentary on the Everett interpretation. Originally published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Peter Byrne tells the story of Hugh Everett III (1930-1982), whose "many worlds" theory of multiple universes has had a profound impact on physics and philosophy. Using Everett's unpublished papers (recently discovered in his son's basement) and dozens of interviews with his friends, colleagues, and surviving family members, Byrne paints, for the general reader, a detailed portrait of the genius who invented an astonishing way of describing our complex universe from the inside. Everett's mathematical model (called the "universal wave function") treats all possible events as "equally real", and concludes that countless copies of every person and thing exist in all possible configurations spread over an infinity of universes: many worlds. Afflicted by depression and addictions, Everett strove to bring rational order to the professional realms in which he played historically significant roles. In addition to his famous interpretation of quantum mechanics, Everett wrote a classic paper in game theory; created computer algorithms that revolutionized military operations research; and performed pioneering work in artificial intelligence for top secret government projects. He wrote the original software for targeting cities in a nuclear hot war; and he was one of the first scientists to recognize the danger of nuclear winter. As a Cold Warrior, he designed logical systems that modeled "rational" human and machine behaviors, and yet he was largely oblivious to the emotional damage his irrational personal behavior inflicted upon his family, lovers, and business partners. He died young, but left behind a fascinating record of his life, including correspondence with such philosophically inclined physicists as Niels Bohr, Norbert Wiener, and John Wheeler. These remarkable letters illuminate the long and often bitter struggle to explain the paradox of measurement at the heart of quantum physics. In recent years, Everett's solution to this mysterious problem - the existence of a universe of universes - has gained considerable traction in scientific circles, not as science fiction, but as an explanation of physical reality.

A Leading Figure in the Development of the New Cosmology Explains What It All Means Among his peers, Alex Vilenkin is regarded as one of the most imaginative and creative cosmologists of our time. His contributions to our current understanding of the universe include a number of novel ideas, two of which—eternal cosmic inflation and the quantum creation of the universe from nothing—have provided a scientific foundation for the possible existence of multiple universes. With this book—his first for the general reader—Vilenkin joins another select group: the handful of first-rank scientists who are equally adept at explaining their work to nonspecialists. With engaging, well-paced storytelling, a droll sense of humor, and a generous sprinkling of helpful cartoons, he conjures up a bizarre and fascinating new worldview that—to paraphrase Niels Bohr—just might be crazy enough to be true.

This volume is dedicated to one of the founding figures of Israeli Chinese studies, Professor Irene Eber of The Hebrew University of Jerusalem. It assembles more than two dozen essays by colleagues from all over the world that reflect not only the wide range of her scholarly interests, but above all the fields of research which would not have been established without her and where her contributions will remain. Accordingly, the section "Philosophy in China and Intellectual History" discusses the thorny and complex process of 'organizing the heritage', from the earliest constructed traditions in Han times around the beginning of our era, up to the debates on modernization in present-day China. After an excursion in "Chinese Literature", much space is devoted to "Translating the Bible in China", a topic on which her numerous studies have proved seminal and that deals with Chinese perceptions. As its complement, perceptions of China in systematic and historical perspective are at the core of the section devoted to "Jewish Life and Letters in the World". The contributions share their approach of paying particular attention to the translation processes strictly speaking and to the hermeneutical process of understanding across time and space more generally. A comprehensive list of publications by Irene Eber concludes the volume.

A World of Many Worlds is a search into the possibilities that may emerge from conversations between indigenous collectives and the study of science's philosophical production. The contributors explore how divergent knowledges and practices make worlds. They work with difference and sameness, recursion, divergence, political ontology, cosmopolitics, and relations, using them as concepts, methods, and analytics to open up possibilities for a pluriverse: a cosmos composed through divergent political practices that do not need to become the same.

An entrepreneurial and engineering genius, Leroy Hill left his mark on 20th century aviation. But that was just the beginning.As a gifted Berkeley engineering graduate in the late teens, Hill succeeded in reengineering the famous "Liberty Engine" of World War I to fit into the legendary fighter DH-4, or "Flying Coffin." In the late 1920s his passion for aviation brought him to a new marketplace as twelve-year president of Air Associates—that remarkable aviation catalog of everything from plane parts and repairs to whole aircraft. Later, in World War II, he founded the company that manufactured and distributed all the hose-clamps for the popular P-51 Mustang Fighter.A true entrepreneur, Leroy Hill was involved in sixty different companies either designing new technologies or marketing improved versions of the old. Politically, he was a lifelong anti-union activist working in the most unionized industries in the nation. Though he marched lockstep with no one, Hill remained to the end of his life a hardbitten opponent of big government who championed many conservative movements of his day.From Leroy Hill's substantial archives, including his voluminous diaries, author Craig Miner has distilled the heady public and private dynamics of an extraordinary life.

This collection covers a wide expanse of topics from metaphysical issues about the nature of existence, to suffering, right action, aesthetic experience and how we live our everyday lives. Intellectual honesty, even skepticism, are important parts of the volume. The poet acknowledges that there are ultimate questions, but denies that there are final answers that could be given by any final authority. We see (Rayn's) keen eye for the beauty of nature and change within nature, and we can watch his keen nose at work, close to nature, sniffing out the joys and suffering of everyday living. - Paul Dolinsky, PhD, from the Preface

Meaning of the journey – around the world, down the path of knowledge orinside one's self – is the search for an endless impact with unknown dimensions, constantly in evolution. This is the book's meaning, its main theme.No path has already been made. "Traveler, there is no path. Paths are madeby walking", states the epigraph by an anonymous Spanish author of thesixteenth century.The main character of The Enchantment of Many Worlds is Vincenzo Parma, an Italian Air Force Brigadier General. Eclectic, well-educated, curious, with an intellectual bravery probably matching his physical one, he tells ushis experiences, his fascinations, his thoughts on different people, cultures, emotions, characters, values, and questions he's been confronting for ages.

Life for twelve year old Mickie Dalton is miserable. Cold, abusive parents make his home intolerable. So when Mickie meets a young couple in the park, an escape opens up. They tell him an astounding truth - Mickie is not a human being, though just what he is, where he came from and how he came to be on Earth are all a mystery. Mickie joins his new guardians on an immense spaceship that travels the Universe, even between galaxies, trading with many intelligent species on other planets as he seeks out his origins and nature. Slowly, he begins to develop extraordinary powers that must have been part of his people. As he also starts to find strange hints of what may have happened, he learns that he is one of an ancient race, the Pfafth who once ruled over forty galaxies but vanished without trace a million years ago. But other forces learn of Mickie's presence, huge forces of immense evil and power that were the cause of the destruction of the Pfafth and now they are intent on finding Mickie and his vanished people so that they can complete the destruction of that ancient race. A million year old war has started again and Mickie must draw on all his astonishing, growing powers and seek the help of allies, some strange, some beautiful, some terrifying as he seeks his people to prevent their end.

The Many Worlds of Sarala Devi Sukhendu Ray With an introduction by Bharati Ray The Tagores and Sartorial Styles Malavika Karlekar Distributed by Berghahn Books on behalf of Social Science Press, Delhi This charming bookThe Many Worlds of Sarala DevandTagores and Sartorial Styles, as the titles suggest, contain two separate but related writings on the Tagores. The Tagores were a pre-eminent family which became synonymous with the cultural regeneration of India, specifically of Bengal, in the nineteenth century. The first writing is a sensitive translation of Sarala Devi’s memoirs from the Bengali,Jeevaner Jharapata, by Sukhendu Ray. It is the first autobiography written by a nationalist woman leader of India. Sarala Devi was Rabindranath Tagore’s niece and had an unusual life. The translation unfolds, among other things, what it was like to grow up in a big affluent houseJorasanko, that had more than 116 inmates and a dozen cooks! The second writing by Malavika Karlekar is a photo essay, creatively conceived, visually reflecting the social and cultural trends of the times, through styles of dress, jewellery and accoutrements. The modern style of wearing asariwas introduced by Jnanadanandini Devi, a member of the Tagore family. The introduction by the well-known historian, Bharati Ray, very perceptively captures the larger context of family, marriage, women’s education and politics of the time which touched Sarala Devi’s life. She points out that if memoirs are a kind of social history then women’s diaries record social influences not found in official accounts and are therefore, a rich source of documentation.

For the better part of a century, attempts to explain what was really going on in the quantum world seemed doomed to failure. But recent technological advances have made the question both practical and urgent. A brilliantly imaginative group of physicists at Oxford University have risen to the challenge. This is their story. At long last, there is a sensible way to think about quantum mechanics. The new view abolishes the need to believe in randomness, long-range spooky forces, or conscious observers with mysterious powers to collapse cats into a state of life or death. But the new understanding comes at a price: we must accept that we live in a multiverse wherein countless versions of reality unfold side-by-side. The philosophical and personal consequences of this are awe-inspiring. The new interpretation has allowed imaginative physicists to conceive of wonderful new technologies: measuring devices that effectively share information between worlds and computers that can borrow the power of other worlds to perform calculations. Step by step, the problems initially associated with the original many-worlds formulation have been addressed and answered so that a clear but startling new picture has emerged. Just as Copenhagen was the centre of quantum discussion a lifetime ago, so Oxford has been the epicenter of the modern debate, with such figures as Roger Penrose and Anton Zeilinger fighting for single-world views, and David Deutsch, Lev Vaidman and a host of others for many-worlds. An independent physicist living in Oxford, Bruce has had a ringside seat to the debate. In his capable hands, we understand why the initially fantastic sounding many-worlds view is not only a useful way to look at things, but logically compelling. Parallel worlds are as real as the distant galaxies detected by the Hubble Space Telescope, even though the evidence for their existence may consist only of a few photons.

Jeffrey Barrett presents the most comprehensive study yet of a problem that has puzzled physicists and philosophers since the 1930s. The standard theory of quantum mechanics is in one sense the most successful physical theory ever, predicting the behaviour of the basic constituents of all physical things; no other theory has ever made such accurate empirical predictions. However, if one tries to understand the theory as providing a complete and accurate framework for the description of the behaviour of all physical interactions, it becomes evident that the theory is ambiguous, or even logically inconsistent. The most notable attempt to formulate the theory so as to deal with this problem, the quantum measurement problem, was initiated by Hugh Everett III in the 1950s. Barrett gives a careful and challenging examination and evaluation of the work of Everett and those who have followed him. His informal approach, minimizing technicality, will make the book accessible and illuminating for philosophers and physicists alike. Anyone interested in the interpretation of quantum mechanics should read it.
