Book excerpt: The problems of indeterminism, uncertainty and statistics in quantum theory are legend and have spawned a wide-variety of interpretations, none too satisfactory.The key issue of discontent is the conflict between the microscopic and the macroscopic worlds: How does a classically certain world emerge from a world of uncertainty and probability? To attempt to solve this riddle, we must first understand the nature of atoms. What If Atoms Are Not Things But Ideas? In the Semantic Interpretation of Quantum Theory atomic objects are treated as symbols of meaning. The book shows that if atoms are symbols, then describing them as meaningless objects would naturally lead to problems of uncertainty, indeterminism, non-locality and probability. For example, if we analyze a book in terms of physical properties, we can measure the frequencies of symbols but not their meanings. Current quantum theory measures symbol probabilities rather than meanings associated with symbol order. Unless quantum objects are treated as symbols, the succession or order amongst these objects will remain unpredictable. Is Quantum Theory a Final Theory of Reality? Quantum Meaning argues that the current quantum theory is not a final theory of reality. Rather, the theory can be replaced by a better one, in which objects are treated as symbols, rendering it free of indeterminism and probability. The Semantic Interpretation makes it possible to formulate new laws of nature. These laws will predict the order amongst symbols, similar to the notes in a musical composition or the words in a book. How This Book Is Structured Chapter 1: Quantum Information--discusses the quantum physics - classical physics conflict and connects it to the historical divide between primary and secondary properties. The consequences of introducing semantic information into physics are described. Chapter 2: The Quantum Problem--surveys the "quantum weirdness" including issue such as discreteness, uncertainty, probability, wave-particle duality, non-locality and irreversibility. Chapter 3: Developing the Intuitions--an informational view of nature is motivated by analyzing the problems that arise when symbols are treated as classical objects. The connection between problems of meaning and Godel's Incompleteness and Turing's Halting Problem are discussed and certain foundational notions such as semantic space and quantum spacelets are introduced. Chapter 4: The Semantic Interpretation--interprets standard constructs in the quantum formalism such as statistics, uncertainty, Schrodinger's equation, non-locality and complementarity. The chapter shows how these constructs cease to be problematic when quanta are treated as symbols. Chapter 5: Advanced Quantum Topics--extends the ideas in the previous chapter to interpret quasi-particles, antiparticles, spin, the weak force, decoherence and the constant speed of light. The chapter discusses a semantic path to Quantum Gravity. Chapter 6: Comparing Interpretations--compares the Semantic Interpretation with some well-known interpretations of quantum theory such as the Copenhagen Interpretation, the Ensemble Interpretation, the Many Worlds Interpretation, the Von Neumann/Wigner Interpretation, the Relational Interpretation, and the Objective Collapse Interpretation. The book concludes by arguing that the quantum wavefunction--which is currently treated physically--can also be treated semantically. Much like a word can be understood as a sound vibration, but also has meaning, the quanta can also be treated as phonemes that symbolize meanings.

Download or read book Field Quantization written by Walter Greiner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical physics has become a many-faceted science. For the young stu dent it is difficult enough to cope with the overwhelming amount of new scientific material that has to be learned, let alone obtain an overview of the entire field, which ranges from mechanics through electrodynamics, quantum mechanics, field theory, nuclear and heavy-ion science, statistical mechanics, thermodynamics, and solid-state theory to elementary-particle physics. And this knowledge should be acquired in just 8-10 semesters, during which, in addition, a Diploma or Master's thesis has to be worked on or examinations prepared for. All this can be achieved only if the university teachers help to introduce the student to the new disciplines as early on as possible, in order to create interest and excitement that in turn set free essential new energy. At the Johann Wolfgang Goethe University in Frankfurt we therefore con front the student with theoretical physics immediately, in the first semester. Theoretical Mechanics I and II, Electrodynamics, and Quantum Mechanics I - An Introduction are the basic courses during the first two years. These lectures are supplemented with many mathematical explanations and much support material. After the fourth semester of studies, graduate work begins, and Quantum Mechanics II - Symmetries, Statistical Mechanics and Ther modynamics, Relativistic Quantum Mechanics, Quantum Electrodynamics, the Gauge Theory of Weak Interactions, and Quantum Chromo dynamics are obligatory.

Download or read book The Emergent Multiverse written by David Wallace and published by OUP Oxford. This book was released on 2012-05-24 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Emergent Multiverse presents a striking new account of the 'many worlds' approach to quantum theory. The point of science, it is generally accepted, is to tell us how the world works and what it is like. But quantum theory seems to fail to do this: taken literally as a theory of the world, it seems to make crazy claims: particles are in two places at once; cats are alive and dead at the same time. So physicists and philosophers have often been led either to give up on the idea that quantum theory describes reality, or to modify or augment the theory. The Everett interpretation of quantum mechanics takes the apparent craziness seriously, and asks, 'what would it be like if particles really were in two places at once, if cats really were alive and dead at the same time'? The answer, it turns out, is that if the world were like that—if it were as quantum theory claims—it would be a world that, at the macroscopic level, was constantly branching into copies—hence the more sensationalist name for the Everett interpretation, the 'many worlds theory'. But really, the interpretation is not sensationalist at all: it simply takes quantum theory seriously, literally, as a description of the world. Once dismissed as absurd, it is now accepted by many physicists as the best way to make coherent sense of quantum theory. David Wallace offers a clear and up-to-date survey of work on the Everett interpretation in physics and in philosophy of science, and at the same time provides a self-contained and thoroughly modern account of it—an account which is accessible to readers who have previously studied quantum theory at undergraduate level, and which will shape the future direction of research by leading experts in the field.

Download or read book A First Course in Loop Quantum Gravity written by Rodolfo Gambini and published by OUP Oxford. This book was released on 2011-09-22 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an accessible introduction to loop quantum gravity and some of its applications, at a level suitable for undergraduate students and others with only a minimal knowledge of college level physics. In particular it is not assumed that the reader is familiar with general relativity and only minimally familiar with quantum mechanics and Hamiltonian mechanics. Most chapters end with problems that elaborate on the text, and aid learning. Applications such as loop quantum cosmology, black hole entropy and spin foams are briefly covered. The text is ideally suited for an undergraduate course in the senior year of a physics major. It can also be used to introduce undergraduates to general relativity and quantum field theory as part of a 'special topics' type of course.

Download or read book Fashionable Nonsense written by Alan Sokal and published by Picador. This book was released on 2014-01-14 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1996 physicist Alan Sokal published an essay in Social Text--an influential academic journal of cultural studies--touting the deep similarities between quantum gravitational theory and postmodern philosophy. Soon thereafter, the essay was revealed as a brilliant parody, a catalog of nonsense written in the cutting-edge but impenetrable lingo of postmodern theorists. The event sparked a furious debate in academic circles and made the headlines of newspapers in the U.S. and abroad. In Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science, Sokal and his fellow physicist Jean Bricmont expand from where the hoax left off. In a delightfully witty and clear voice, the two thoughtfully and thoroughly dismantle the pseudo-scientific writings of some of the most fashionable French and American intellectuals. More generally, they challenge the widespread notion that scientific theories are mere "narrations" or social constructions.

Download or read book QED written by Richard P. Feynman and published by Princeton University Press. This book was released on 2014-10-26 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feynman’s bestselling introduction to the mind-blowing physics of QED—presented with humor, not mathematics Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the public. In this extraordinary book, Feynman provides a lively and accessible introduction to QED, or quantum electrodynamics, an area of quantum field theory that describes the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned Feynman diagrams instead of advanced mathematics, Feynman clearly and humorously communicates the substance and spirit of QED to the nonscientist. With an incisive introduction by A. Zee that places Feynman’s contribution to QED in historical context and highlights Feynman’s uniquely appealing and illuminating style, this Princeton Science Library edition of QED makes Feynman’s legendary talks on quantum electrodynamics available to a new generation of readers.
