Veiled Reality


Book Description

By questioning the validity of some of our basic concepts, such as space, object, and causality, quantum physics contributes quite decisively to the dramatic changes now taking place in our world picture.This book is addressed not only to physicists at an early stage in their careers (the first or second year graduate student) but also to philosophers, as well as to all the senior physicists interested in the interpretation problem. Beginning with a chapter that could be described as “philosophy for physicists,” it presents an in-depth analysis of present-day quantum mechanical concepts, an analysis of physicists and philosophers alike. Specifically, it first offers an extensive critical analysis of such topics as the Einstein, Podolsky, Rosen reality criterion, nonseparatability, the quantum measurement riddle, decoherence theory, consistent histories approaches and ontologically interpretable theories. All this then naturally leads to philosophical questions concerning, in particular, intersubjective agreement and the limit of realism. And a thorough examination of this whole material finally leads to the view that distinguishing between empirical reality and a veiled man-independent reality yields an acceptable answer to the perplexing question of how to interpret quantum physics. Veiled Reality offers nonspecialists, including students in physics, philosophy and the history of science, an accessible perspective on basic problems in the foundations of physics.




Do We Really Understand Quantum Mechanics?


Book Description

Gives an overview of the quantum theory and its main interpretations. Ideal for researchers in physics and mathematics.




In Search of Reality


Book Description

When I take up a new book I always read its conclusions first. For I have discovered that even difficult books have conclusions that are easy to read and that give a first idea of their content. Of course, I expect my readers to do this also! Indeed, the present book offers them an opportunity for generalizing the method. After having gone over chapter 14 they should preferably look through chapters 5, 2, 13 and 10, or at least some of these (in this or in other orders), before engaging into any thorough reading. The point is that-at appropriate places in other chapters-the reader will find proofs; and, as we all know, all the proofs that are worth something are unavoidably ponderous. Of course, it is good to have them but, again, the most suitable procedure not to lose interest in their development is, I think, to first provisionally grant their conclusions,. in order to see where they lead us to. Then, to study the proofs once we have been convinced that the goal is worth some effort. This is the reason why I suggest that at least chapters 4 and 11 should, on a first reading, be skipped, at any rate, by the "poets"! The problem, a new approach of which is described in chapter 4, did not come to light, at least in its present form, before 1964. The first experi mental investigations bearing on it date back from the seventies.




Making Human Rights a Reality


Book Description

In the last six decades, one of the most striking developments in international law is the emergence of a massive body of legal norms and procedures aimed at protecting human rights. In many countries, though, there is little relationship between international law and the actual protection of human rights on the ground. Making Human Rights a Reality takes a fresh look at why it's been so hard for international law to have much impact in parts of the world where human rights are most at risk. Emilie Hafner-Burton argues that more progress is possible if human rights promoters work strategically with the group of states that have dedicated resources to human rights protection. These human rights "stewards" can focus their resources on places where the tangible benefits to human rights are greatest. Success will require setting priorities as well as engaging local stakeholders such as nongovernmental organizations and national human rights institutions. To date, promoters of international human rights law have relied too heavily on setting universal goals and procedures and not enough on assessing what actually works and setting priorities. Hafner-Burton illustrates how, with a different strategy, human rights stewards can make international law more effective and also safeguard human rights for more of the world population.




On Physics and Philosophy


Book Description

Among the great ironies of quantum mechanics is not only that its conceptual foundations seem strange even to the physicists who use it, but that philosophers have largely ignored it. Here, Bernard d'Espagnat argues that quantum physics--by casting doubts on once hallowed concepts such as space, material objects, and causality-demands serious reconsideration of most of traditional philosophy. On Physics and Philosophy is an accessible, mathematics-free reflection on the philosophical meaning of the quantum revolution, by one of the world's leading authorities on the subject. D'Espagnat presents an objective account of the main guiding principles of contemporary physics-in particular, quantum mechanics-followed by a look at just what consequences these should imply for philosophical thinking. The author begins by describing recent discoveries in quantum physics such as nonseparability, and explicating the significance of contemporary developments such as decoherence. Then he proceeds to set various philosophical theories of knowledge--such as materialism, realism, Kantism, and neo-Kantism--against the conceptual problems quantum theory raises. His overall conclusion is that while the physical implications of quantum theory suggest that scientific knowledge will never truly describe mind-independent reality, the notion of such an ultimate reality--one we can never access directly or rationally and which he calls "veiled reality"--remains conceptually necessary nonetheless.

Veiled Freedom


Book Description

When Special Forces veteran Steve Wilson returns to Kabul as security chief to the minister of interior, he is disillusioned with the corriuption and violence that has overtaken the country he fought to free. Relief worker Amy Mallory arrives in Afghanistan ready to change the world. She soon discovers that as a Western woman, the challenges are monumental. Afghan native Jamil returns to his homeland seeking work, but a painful past continues to haunt him. All three are searching for truth and freedom when a suicide bombing brings them together on Kabul's dusty streets.--From publisher's description.




Semiclassical Physics


Book Description

This book attempts to convey to the reader that semiclassical physics can be fun, as well as useful for understanding quantum fluctuations in interacting many-body systems. It presents applications to finite fermion systems in diverse areas of physics.




Conformal Field Theory


Book Description

This book provides an understanding of conformal field theory and its importance to both statistical mechanics and string theory. It introduces the Wess-Zumino-Novokov-Witten (WZNW) models and their current algebras, the affine Kac-Moody algebras.
