This text presents an intuitive and robust mathematical image of fundamental particle physics based on a novel approach to quantum field theory, which is guided by four carefully motivated metaphysical postulates. In particular, the book explores a dissipative approach to quantum field theory, which is illustrated for scalar field theory and quantum electrodynamics, and proposes an attractive explanation of the Planck scale in quantum gravity. Offering a radically new perspective on this topic, the book focuses on the conceptual foundations of quantum field theory and ontological questions. It also suggests a new stochastic simulation technique in quantum field theory which is complementary to existing ones. Encouraging rigor in a field containing many mathematical subtleties and pitfalls this text is a helpful companion for students of physics and philosophers interested in quantum field theory, and it allows readers to gain an intuitive rather than a formal understanding.

The Oxford Handbook of Philosophy of Physics

Author: Robert Batterman

Publisher: Oxford University Press

ISBN: 0195392043

Category: Philosophy

This Oxford Handbook provides an overview of many of the topics that currently engage philosophers of physics. It surveys new issues and the problems that have become a focus of attention in recent years. It also provides up-to-date discussions of the still very important problems that dominated the field in the past. In the late 20th Century, the philosophy of physics was largely focused on orthodox Quantum Mechanics and Relativity Theory. The measurement problem, the question of the possibility of hidden variables, and the nature of quantum locality dominated the literature on the quantum mechanics, whereas questions about relationalism vs. substantivalism, and issues about underdetermination of theories dominated the literature on spacetime. These issues still receive considerable attention from philosophers, but many have shifted their attentions to other questions related to quantum mechanics and to spacetime theories. Quantum field theory has become a major focus, particularly from the point of view of algebraic foundations. Concurrent with these trends, there has been a focus on understanding gauge invariance and symmetries. The philosophy of physics has evolved even further in recent years with attention being paid to theories that, for the most part, were largely ignored in the past. For example, the relationship between thermodynamics and statistical mechanics—-once thought to be a paradigm instance of unproblematic theory reduction—-is now a hotly debated topic. The implicit, and sometimes explicit, reductionist methodology of both philosophers and physicists has been severely criticized and attention has now turned to the explanatory and descriptive roles of "non-fundamental,'' phenomenological theories. This shift of attention includes "old'' theories such as classical mechanics, once deemed to be of little philosophical interest. Furthermore, some philosophers have become more interested in "less fundamental'' contemporary physics such as condensed matter theory. Questions abound with implications for the nature of models, idealizations, and explanation in physics. This Handbook showcases all these aspects of this complex and dynamic discipline.

Ontological Aspects of Quantum Field Theory

Author: Meinard Kuhlmann,Holger Lyre,Andrew Wayne

Publisher: World Scientific

ISBN: 9812381821

Category: Science

Page: 362

View: 375

Quantum field theory (QFT) provides the framework for many fundamental theories in modern physics, and over the last few years there has been growing interest in its historical and philosophical foundations. This anthology on the foundations of QFT brings together 15 essays by well-known researchers in physics, the philosophy of physics, and analytic philosophy.Many of these essays were first presented as papers at the conference ?Ontological Aspects of Quantum Field Theory?, held at the Zentrum fr interdisziplin„re Forschung (ZiF), Bielefeld, Germany. The essays contain cutting-edge work on ontological aspects of QFT, including: the role of measurement and experimental evidence, corpuscular versus field-theoretic interpretations of QFT, the interpretation of gauge symmetry, and localization.This book is ideally suited to anyone with an interest in the foundations of quantum physics, including physicists, philosophers and historians of physics, as well as general readers interested in philosophy or science.

The Quantum Revolution in Philosophy

Author: Richard Healey

Publisher: Oxford University Press

ISBN: 019871405X

Category: Philosophy

Page: 288

View: 809

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.

The Philosophy of Quantum Physics

This book provides a thorough and up-to-date introduction to the philosophy of quantum physics. Although quantum theory is renowned for its spectacular empirical successes, controversial discussion about how it should be understood continue to rage today. In this volume, the authors provide an overview of its numerous philosophical challenges: Do quantum objects violate the principle of causality? Are particles of the same type indistinguishable and therefore not individual entities? Do quantum objects retain their identity over time? How does a compound quantum system relate to its parts? These questions are answered here within different interpretational approaches to quantum theory. Finally, moving to Quantum Field Theory, we find that the problem of non-locality is exacerbated. Philosophy of quantum physics is aimed at philosophers with an interest in physics, while also serving to familiarize physicists with many of the essential philosophical questions of their subject.

Religion ohne Gott

Author: Ronald Dworkin

Publisher: Suhrkamp Verlag

ISBN: 3518737325

Category: Philosophy

Page: 146

View: 2930

Das Zentrum wahrer Religiosität, so der bekennende Atheist Albert Einstein, sei die Ehrfurcht vor den Mysterien des Universums, »deren höchste Weisheit und strahlende Schönheit wir mit unseren matten Erkenntnisvermögen nur rudimentär begreifen können«. In diesem Sinne sei er, Einstein, ein tiefreligiöser Mensch. Aber was ist religiös an einer solchen Haltung, in der Gott offensichtlich keine Rolle spielt? Mit dieser Frage beschäftigte sich Ronald Dworkin in seinen Einstein-Vorlesungen, die er bis kurz vor seinem Tod zu diesem Buch ausgearbeitet hat. Religion, so seine Antwort, bezeichnet eine Sicht auf die Welt, die von einem tiefen Glauben an objektive Werte getragen wird – etwa daran, dass Geschöpfe eine Würde haben, dass ein Leben erfüllt oder verfehlt sein kann oder dass Schönheit, die uns den Atem raubt, sich nicht als pures Produkt unserer Sinnesorgane erklären lässt. Auch Theisten teilen diese Werte, meinen aber, sie seien gottgegeben. Für Dworkin verhält es sich genau umgekehrt: Die Idee eines Gottes rührt daher, dass es diese Werte wirklich gibt. Und an Gott (oder Götter) zu glauben ist eine Weise, dies auszudrücken, aber nicht die einzige. Von der Physik über die Politik bis hin zum Recht erkundet »Religion ohne Gott« den Perspektivwechsel, der mit einem solchen gottlosen Verständnis von Religion verbunden ist. Das Buch, das mit einer eindrucksvollen Reflexion über Tod und Unsterblichkeit schließt, ist das Vermächtnis eines bekennenden religiösen Atheisten. Es weitet den Blick für das, was wichtig ist.

Sie lesen jetzt das Wort »jetzt« – und schon ist es vergangen. Das flüchtige Dasein der Gegenwart hat Philosophen und Physiker vor die größten Rätsel gestellt: Was ist die Zeit? Und warum fließt sie? Generationen von Wissenschaftlern haben sich vergeblich um Antworten bemüht, einige haben es aufgegeben. Nicht so Richard A. Muller. Er hat eine Theorie der Zeit aufgestellt, die neu ist und experimentell überprüfbar. Um sie vorzustellen, erklärt er zunächst mit großem Geschick die physikalischen Grundkonzepte wie Relativität, Entropie, Verschränkung, Antimaterie und Urknall. Darauf aufbauend entfaltet er seine provozierend neue Sicht mit all ihren Folgen für die Philosophie oder die Frage nach der Willensfreiheit. Eine kraftvolle und überzeugende Vision für die Lösung des alten Rätsels der Zeit. »Muller hat einen bemerkenswert frischen und aufregenden Ansatz für die Erklärung der Zeit.« Saul Perlmutter, Physik-Nobelpreisträger »Ein provokatives und gut argumentiertes Buch über die Natur der Zeit.« Lee Smolin
