Available in PDF, EPUB and Kindle. Book excerpt: Measured by the accuracy of its predictions and the scope of its technological applications, quantum mechanics is one of the most successful theories in science—as well as one of the most misunderstood. The deeper meaning of quantum mechanics remains controversial almost a century after its invention. Providing a way past quantum theory’s paradoxes and puzzles, QBism offers a strikingly new interpretation that opens up for the nonspecialist reader the profound implications of quantum mechanics for how we understand and interact with the world. Short for Quantum Bayesianism, QBism adapts many of the conventional features of quantum mechanics in light of a revised understanding of probability. Bayesian probability, unlike the standard “frequentist probability,” is defined as a numerical measure of the degree of an observer’s belief that a future event will occur or that a particular proposition is true. Bayesianism’s advantages over frequentist probability are that it is applicable to singular events, its probability estimates can be updated based on acquisition of new information, and it can effortlessly include frequentist results. But perhaps most important, much of the weirdness associated with quantum theory—the idea that an atom can be in two places at once, or that signals can travel faster than the speed of light, or that Schrödinger’s cat can be simultaneously dead and alive—dissolves under the lens of QBism. Using straightforward language without equations, Hans Christian von Baeyer clarifies the meaning of quantum mechanics in a commonsense way that suggests a new approach to physics in general.

Download or read book Phenomenology and QBism written by Philipp Berghofer and published by Taylor & Francis. This book was released on 2023-12-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together philosophers and physicists to explore the parallels between Quantum Bayesianism, or QBism, and the phenomenological tradition. It is the first book exclusively devoted to phenomenology and quantum mechanics. By emphasizing the role of the subject’s experiences and expectations, and by explicitly rejecting the idea that the notion of physical reality could ever be reduced to a purely third-person perspective, QBism exhibits several interesting parallels with phenomenology. The central message of QBism is that quantum probabilities must be interpreted as the experiencing agent’s personal Bayesian degrees of belief – degrees of belief for the consequences of their actions on a quantum system. The chapters in this volume elaborate on whether and specify how phenomenology could serve as the philosophical foundation of QBism. This objective is pursued from the perspective of QBists engaging with phenomenology as well as the perspective of phenomenologists engaging with QBism. These approaches enable us to realize a better understanding of quantum mechanics and the world we live in, achieve a better understanding of QBsim, and introduce the phenomenological foundations of quantum mechanics. Phenomenology and QBism is an essential resource for researchers and graduate students working in the philosophy of physics, philosophy of science, quantum mechanics, and phenomenology.
Download or read book The Quantum Revolution in Philosophy written by Richard Healey and published by Oxford University Press. This book was released on 2017-06-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum theory launched a revolution in physics. But we have yet to understand the revolution's significance for philosophy. Richard Healey opens a path to such understanding. Most studies of the conceptual foundations of quantum theory first try to interpret the theory - to say how the world could possibly be the way the theory says it is. But, though fundamental, quantum theory is enormously successful without describing the world in its own terms. When properly applied, models of quantum theory offer good advice on the significance and credibility of claims about the world expressed in other terms. This first philosophical lesson of the quantum revolution dissolves the quantum measurement problem. Pragmatist treatments of probability and causation show how quantum theory may be used to explain the non-localized correlations that have been thought to involve "spooky" instantaneous action at a distance. Given environmental decoherence, a pragmatist inferentialist approach to content shows when talk of quantum probabilities is licensed, resolves any residual worries about whether a quantum measurement has a determinate outcome, and solves a dilemma about the ontology of a quantum field theory. This approach to meaning and reference also reveals the nature and limits of objective description in the light of quantum theory. While these pragmatist approaches to probability, causation, explanation and content may be independently motivated by philosophical argument, their successful application here illustrates their practical importance in helping philosophers come to terms with the quantum revolution.
Download or read book Something Deeply Hidden written by Sean Carroll and published by Penguin. This book was released on 2020-09-01 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: INSTANT NEW YORK TIMES BESTSELLER As you read these words, copies of you are being created. Sean Carroll, theoretical physicist and one of this world’s most celebrated writers on science, rewrites the history of twentieth-century physics. Already hailed as a masterpiece, Something Deeply Hidden shows for the first time that facing up to the essential puzzle of quantum mechanics utterly transforms how we think about space and time. His reconciling of quantum mechanics with Einstein’s theory of relativity changes, well, everything. Most physicists haven’t even recognized the uncomfortable truth: Physics has been in crisis since 1927. Quantum mechanics has always had obvious gaps—which have come to be simply ignored. Science popularizers keep telling us how weird it is, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line with this audacious yet entirely reasonable book, Carroll says that the crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. Copies of you are generated thousands of times per second. The Many-Worlds theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn't happen. Step-by-step in Carroll's uniquely lucid way, he tackles the major objections to this otherworldly revelation until his case is inescapably established. Rarely does a book so fully reorganize how we think about our place in the universe. We are on the threshold of a new understanding—of where we are in the cosmos, and what we are made of.
Download or read book Quantum Entanglement written by Jed Brody and published by MIT Press. This book was released on 2020-02-18 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of quantum entanglement and the ways in which it contradicts our everyday assumptions about the ultimate nature of reality. Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement—called by Einstein “spooky action at a distance”—rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying? In this volume in the MIT Press Essential Knowledge series, Jed Brody equips readers to decide for themselves. He explains how our commonsense assumptions impose constraints—from which entangled particles break free. Brody explores such concepts as local realism, Bell's inequality, polarization, time dilation, and special relativity. He introduces readers to imaginary physicists Alice and Bob and their photon analyses; points out that it's easier to reject falsehood than establish the truth; and reports that some physicists explain entanglement by arguing that we live in a cross-section of a higher-dimensional reality. He examines a variety of viewpoints held by physicists, including quantum decoherence, Niels Bohr's Copenhagen interpretation, genuine fortuitousness, and QBism. This relatively recent interpretation, an abbreviation of “quantum Bayesianism,” holds that there's no such thing as an absolutely accurate, objective probability “out there,” that quantum mechanical probabilities are subjective judgments, and there's no “action at a distance,” spooky or otherwise.
Download or read book On Theories written by William Demopoulos and published by Harvard University Press. This book was released on 2021-12-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: A renowned philosopherÕs final work, illuminating how the logical empiricist tradition has failed to appreciate the role of actual experiments in forming its philosophy of science. The logical empiricist treatment of physics dominated twentieth-century philosophy of science. But the logical empiricist tradition, for all it accomplished, does not do justice to the way in which empirical evidence functions in modern physics. In his final work, the late philosopher of science William Demopoulos contends that philosophers have failed to provide an adequate epistemology of science because they have failed to appreciate the tightly woven character of theory and evidence. As a consequence, theory comes apart from evidence. This trouble is nowhere more evident than in theorizing about particle and quantum physics. Arguing that we must consider actual experiments as they have unfolded across history, Demopoulos provides a new epistemology of theories and evidence, albeit one that stands on the shoulders of giants. On Theories finds clarity in Isaac NewtonÕs suspicion of mere Òhypotheses.Ó NewtonÕs methodology lies in the background of Jean PerrinÕs experimental investigations of molecular reality and of the subatomic investigations of J. J. Thomson and Robert Millikan. Demopoulos extends this account to offer novel insights into the distinctive nature of quantum reality, where a logico-mathematical reconstruction of Bohrian complementarity meets John Stewart BellÕs empirical analysis of EinsteinÕs Òlocal realism.Ó On Theories ultimately provides a new interpretation of quantum probabilities as themselves objectively representing empirical reality.
Download or read book Through Two Doors at Once written by Anil Ananthaswamy and published by Penguin. This book was released on 2019-06-11 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself--and continues to almost two hundred years later. Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment. Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe. How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit? With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.
Download or read book Quantum Mechanics Between Ontology and Epistemology written by Florian J. Boge and published by Springer. This book was released on 2018-10-24 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the prospects of rivaling ontological and epistemic interpretations of quantum mechanics (QM). It concludes with a suggestion for how to interpret QM from an epistemological point of view and with a Kantian touch. It thus refines, extends, and combines existing approaches in a similar direction. The author first looks at current, hotly debated ontological interpretations. These include hidden variables-approaches, Bohmian mechanics, collapse interpretations, and the many worlds interpretation. He demonstrates why none of these ontological interpretations can claim to be the clear winner amongst its rivals. Next, coverage explores the possibility of interpreting QM in terms of knowledge but without the assumption of hidden variables. It examines QBism as well as Healey’s pragmatist view. The author finds both interpretations or programs appealing, but still wanting in certain respects. As a result, he then goes on to advance a genuine proposal as to how to interpret QM from the perspective of an internal realism in the sense of Putnam and Kant. The book also includes two philosophical interludes. One details the notions of probability and realism. The other highlights the connections between the notions of locality, causality, and reality in the context of violations of Bell-type inequalities.

Download or read book Phenomenological Approaches to Physics written by Harald A. Wiltsche and published by Springer Nature. This book was released on 2020-06-23 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers fresh perspective on the role of phenomenology in the philosophy of physics which opens new avenues for discussion among physicists, "standard" philosophers of physics and philosophers with phenomenological leanings. Much has been written on the interrelations between philosophy and physics in the late 19th and early 20th century, and on the emergence of philosophy of science as an autonomous philosophical sub-discipline. This book is about the under-explored role of phenomenology in the development and the philosophical interpretation of 20th century physics. Part 1 examines questions about the origins and value of phenomenological approaches to physics. Does the work of classical phenomenologists such as Husserl, Merleau-Ponty or Heidegger contain elements of systematic value to both the practice and our philosophical understanding of physics? How did classical phenomenology influence “standard” philosophy of science in the Anglo-American and other traditions? Part 2 probes questions on the role of phenomenology in the philosophies of physics and science: - Can phenomenology help to solve “Wigner’s puzzle”, the problem of the "unreasonable effectiveness" of mathematics in describing, explaining and predicting empirical phenomena? - Does phenomenology allow better understanding of the principle of gauge invariance at the core of the standard model of contemporary particle physics? - Does the phenomenological notion of “Lifeworld” stand in opposition to the “scientific metaphysics” movement, or is there potential for dialogue? Part 3 examines the measurement problem. Is the solution outlined by Fritz London and Edmond Bauer merely a re-statement of von Neumann’s view, or should it be regarded as a distinctively phenomenological take on the measurement problem? Is phenomenology a serious contender in continuing discussions of foundational questions of quantum mechanics? Can other interpretational frameworks such as quantum Bayesianism benefit from implementing phenomenological notions such as constitution or horizonal intentionality?
Download or read book Rabi Scientist Citizen written by John Rigden and published by Plunkett Lake Press. This book was released on 2019-08-15 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Rabi’s voice comes through vividly and forcefully. This is a work of great inspiration.” — Aage Bohr, Professor of Physics, Niels Bohr Institute, Copenhagen, Denmark “This excellent work is the first full biography of Professor Rabi, the scientist who epitomizes the passing of the torch of physics from Europe to the United States almost a half-century ago. As I read this biography it was almost as if Rabi himself were retelling these events so that all can share his memories of those exciting and important years and benefit from his experience and wisdom.” — Rosalyn S. Yalow, Nobel Laureate in Medicine “A delightful book about a delightful man. Rabi always found a simpler way to do any given experiment, and this made him a great physicist. He has now become a sage who has given the most useful advice to all his colleagues.” — Hans A. Bethe, Nobel Laureate in Physics and Professor Emeritus of Physics, Cornell University “A steadily fascinating account of an exemplary life. Rigden gives the lay reader a clear idea of what the physicist is seeing, what leads him to such strange thoughts. His account of ‘The Matter of J. Robert Oppenheimer’ gives more useful information in a few pages than I could find in the near thousand-page transcript of the hearings.” —Howard Nemerov, Pulitzer Prize-winning Poet and Professor of English, Washington University “An admirable biography, the best possible replacement for the memoirs that Rabi never found time to write.” McGeorge Bundy, Professor of History, New York University “The twentieth century [was] a time of high adventure in physics. It is no wonder that Rabi, with his ebullience and complex genius and wisdom found his profession ‘wonderful.’ As Rigden demonstrates in this complete and very good book, physics was wonderful for Rabi and Rabi was wonderful for physics.” — R. R. Wilson, Science “The growth, in this century, of the American physics community — in size, stature, and influence — is certainly a historical development with deep roots and profound implications. John Rigden’s Rabi: Scientist and Citizen is a fascinating treatment of that subject as reflected in the career and person of Isidor I. Rabi... The [book] sets forth in coherent and sometimes passionate prose an impressive account of I. I. Rabi’s self-image and vision, a vision shared by an important group of physicist colleagues... an engaging personal portrait.” — Allan A. Needell, Isis: A Journal of the History of Science “A real tour de force and a pleasure to read.” — John G. King, Physics Today “Rabi’s life was remarkable, full of incident, vision and action, including war, hot and cold. The biography is a masterpiece, rich in anecdote and never losing the narrative drive.” — New Scientist “Nobel prize-winning physicist I. I. Rabi was described by journalist Daniel Greenberg in 1967 as the éminence grise of America’s scientific establishment. During the Second World War he was in charge of radar research as an associate director of the MIT Radiation Laboratory and was a senior consultant for Los Alamos Scientific Laboratory. After the war he helped to establish the Brookhaven National Laboratory; he sat on the General Advisory Committee (GAC) of the Atomic Energy Commission, eventually succeeding Oppenheimer as chairman; under Eisenhower he was an architect of the president’s Science Advisory Committee. As an elder statesman in the American Cold War scientific community, he was concerned to solidify both the political and the cultural power of science. John S. Rigden’s biography of Rabi, now reissued with a new preface by the author, emphasizes Rabi’s view of science as properly not just a source of technological and military strength, but as ‘the center of culture’.” — Charles Thorpe, British Journal for the History of Science “Rigden, physicist and editor of the American Journal of Physics, has created an intimate portrait of this Titan of 20th century science... The book takes the reader into a world where powerful physical forces and powerful political forces come together to shape our century.” — Bulletin of Science, Technology & Society “[A] satisfying, sympathetic portrait of a modest, brilliant scientist who regards his calling as ‘sacred,’ a religious exploration of ‘one God,’ the God being nature. Readers will treasure equally the story of Rabi’s molecular-beam experiments which earned him the Nobel Prize in 1944 and a gallery of revealing glimpses of his scientist friends, chief among them J. Robert Oppenheimer.” — Publishers Weekly “I. I. Rabi is one of this country’s most distinguished physicists... his life has encompassed all of this century and the revolution in physics that it produced... an interesting story, ably told by John S. Rigden, a physicist at the University of Missouri-St. Louis.” — Lee Dembart, Los Angeles Times

Download or read book Eco Phenomenology written by Charles S. Brown and published by State University of New York Press. This book was released on 2012-02-01 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking collection explores the intersection of phenomenology with environmental philosophy. It examines the relevance of Husserl, Heidegger, Merleau-Ponty, and Levinas for thinking through the philosophical dilemmas raised by environmental issues, and then proposes new phenomenological approaches to the natural world. The contributors demonstrate phenomenology's need to engage in an ecological self-evaluation and to root out anthropomorphic assumptions embedded in its own methodology. Calling for a reexamination of beliefs central to the Western philosophical tradition, this book shifts previously marginalized environmental concerns to the forefront and blazes a trail for a new collaboration between phenomenologists and ecologically-minded theorists.
Download or read book Blindsight written by Matt Johnson and published by BenBella Books. This book was released on 2020-05-19 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever notice that all watch ads show 10:10 as the time? Or that all fast-food restaurants use red or yellow in their logos? Or that certain stores are always having a sale? You may not be aware of these details, yet they've been influencing you all along. Every time you purchase, swipe, or click, marketers are able to more accurately predict your behavior. These days, brands know more about you than you know about yourself. Blindsight is here to change that. With eye-opening science, engaging stories, and fascinating real-world examples, neuroscientist Matt Johnson and marketer Prince Ghuman dive deep into the surprising relationship between brains and brands. In Blindsight, they showcase how marketing taps every aspect of our mental lives, covering the neuroscience of pain and pleasure, emotion and logic, fear and safety, attention and addiction, and much more. We like to think of ourselves as independent actors in control of our decisions, but the truth is far more complicated. Blindsight will give you the ability to see the unseeable when it comes to marketing, so that you can consume on your own terms. On the surface, you will learn how the brain works and how brands design for it. But peel back a layer, and you'll find a sharper image of your psychology, reflected in your consumer behavior. This book will change the way you view not just branding, but yourself, too.
Download or read book 101 Quantum Questions written by Kenneth W. Ford and published by Harvard University Press. This book was released on 2011-03-31 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ken Ford’s mission is to help us understand the “great ideas” of quantum physics—ideas such as wave-particle duality, the uncertainty principle, superposition, and conservation. These fundamental concepts provide the structure for 101 Quantum Questions, an authoritative yet engaging book for the general reader in which every question and answer brings out one or more basic features of the mysterious world of the quantum—the physics of the very small. Nuclear researcher and master teacher, Ford covers everything from quarks, quantum jumps, and what causes stars to shine, to practical applications ranging from lasers and superconductors to light-emitting diodes. Ford’s lively answers are enriched by Paul Hewitt's drawings, numerous photos of physicists, and anecdotes, many from Ford’s own experience. Organized for cover-to-cover reading, 101 Quantum Questions also is great for browsing. Some books focus on a single subject such as the standard model of particles, or string theory, or fusion energy. This book touches all those topics and more, showing us that disparate natural phenomena, as well as a host of manmade inventions, can be understood in terms of a few key ideas. Yet Ford does not give us simplistic explanations. He assumes a serious reader wanting to gain real understanding of the essentials of quantum physics. Ken Ford's other books include The Quantum World: Quantum Physics for Everyone (Harvard 2004), which Esquire magazine recommended as the best way to gain an understanding of quantum physics. Ford's new book, a sequel to the earlier one, makes the quantum world even more accessible.
Download or read book World According To Quantum Mechanics The Why The Laws Of Physics Make Perfect Sense After All Second Edition written by Ulrich Mohrhoff and published by World Scientific. This book was released on 2018-10-12 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The authors should be recognised for their efforts to present a mathematically rigorous introduction to Quantum Mechanics (QM) in a form that has broad appeal; there are not many introductory QM texts that would cover, for example, decoherence. I think many educators would appreciate this book, especially those interested in courses that combine science and philosophy.'Contemporary PhysicsApart from providing a lucid introduction to the mathematical formalism and conceptual foundations of quantum mechanics, we explain why the laws of physics have the form that they do. In addition, we present a new and unique look at the quantum world, steering clear of two common errors: the error of the ψ-ontologists, who reify a calculational tool; and the error of the anti-realists, for whom physical theories are simply devices for expressing regularities among observations.The new edition of this acclaimed text adds around 200 pages on a variety of topics, such as how the founders sought to make sense of quantum mechanics, Kant's theory of science, QBism, Everettian quantum mechanics, de Broglie-Bohm theory, environmental decoherence, contextuality, nonlocality, and the paradox of subjectivity — the curious fact that the world seems to exist twice, once for us, in our minds, and once by itself, independently of us.
