This book is the first complete and comprehensive description of the modern Physical Theory of Diffraction (PTD) based on the concept of elementary edge waves (EEWs). The theory is demonstrated with the example of the diffraction of acoustic and electromagnetic waves at perfectly reflecting objects. The derived analytic expressions clearly explain the physical structure of the scattered field and describe in detail all of the reflected and diffracted rays and beams, as well as the fields in the vicinity of caustics and foci. Shadow radiation, a new fundamental component of the field, is introduced and proven to contain half of the total scattered power.

In nine new essays, distinguished philosophers of science take on outstanding philosophical issues that arise in the exploration of the foundations of contemporary, especially physical scientific theories. In the first part of the book issues of scientific method are explored. What are we asking when we pose scientific "why?" questions? How does probability play a role in answering such questions? What are scientific laws of nature? How can we understand what abstract theories are telling us about the world? What is the structure of the theories we use to explain the observable phenomena? Finally, how do theories evolve over time and what consequence do such changes have for our intuition that science is seeking the truth? In the second part of the volume, foundational issues are explored in a number of crucial physical theories. What do our best available theories tell us about space and time? When we apply quantum theory to fields or other systems with infinite degrees of freedom, what new foundational puzzles appear and how might a theory of interpretation deal with them? Finally, what are the crucial foundational issues in statistical mechanics, where probabilities are applied to explain macroscopic thermal phenomena?

Professor Bondi discusses some of the myths that have grown up around various scientific theories and ideas, particularly special relativity and Mach's principle. His critical - and often light-hearted - approach to what are usually regarded as complicated ideas leaves the reader with the feeling that perhaps much of his subject is common sense after all. Professor Bondi's aim is to provoke thought, rather than to provide all the answers. He first discusses the limits of theory-making, the significance of depth and universality and the devising of effective tests for scientific theories. The relation of Einstein's theory to classical Newtonian mechanics is then considered, the author showing that relativity can be regarded simple as an extension of Newton's ideas on dynamics to the whole of physics. After deriving the equations of special relativity by the so-called k-calculus, he disposes rapidly of the 'clock paradox' and moves on to discuss general relativity, the significance of the result of Newman and Penrose concerning gravitational waves, the sources of gravitation and inertia, Mach's principles and the Hoyle-Narlikar relativity theory.

This book deals with some of the current issues in the philosophy, methodology and foundations of physics. Some such problems are: - Do mathematical formalisms interpret themselves or is it necessary to adjoin them interpretation assumptions, and if so how are these as sumptions to be framed? - What are physical theories about: physical systems or laboratory operations or both or neither? - How are the basic concepts of a theory to be introduced: by ref erence to measurements or by explicit definition or axiomatically? - What is the use ofaxiomatics in physics? - How are the various physical theories inter-related: like Chinese boxes or in more complex ways? - What is the role of analogy in the construction and in the inter pretation of physical theories? In particular, are classical analogues like those of particle and wave indispensable in quantum theories? - What is the role of the apparatus in quantum phenomena and what is the place of measurement theory in quantum mechanics? - How does a theory face experiment: single-handed or with the help of further theories? These and several other questions of the kind are met with by the research physicist, the physics teacher and the physics student in their everyday work. If dodged they will recur. And a wrong answer to them may obscure the understanding of what has been achieved and may even hamper further advancement. Philosophy, methodology and foundations, like rose bushes, are enjoyable when cultivated but become ugly and thorny when neglected.

Undergraduates in engineering and the physical sciences receive a thorough introduction to perturbation theory in this useful and accessible text. Students discover methods for obtaining an approximate solution of a mathematical problem by exploiting the presence of a small, dimensionless parameter — the smaller the parameter, the more accurate the approximate solution. Knowledge of perturbation theory offers a twofold benefit: approximate solutions often reveal the exact solution's essential dependence on specified parameters; also, some problems resistant to numerical solutions may yield to perturbation methods. In fact, numerical and perturbation methods can be combined in a complementary way. The text opens with a well-defined treatment of finding the roots of polynomials whose coefficients contain a small parameter. Proceeding to differential equations, the authors explain many techniques for handling perturbations that reorder the equations or involve an unbounded independent variable. Two disparate practical problems that can be solved efficiently with perturbation methods conclude the volume. Written in an informal style that moves from specific examples to general principles, this elementary text emphasizes the "why" along with the "how"; prerequisites include a knowledge of one-variable calculus and ordinary differential equations. This newly revised second edition features an additional appendix concerning the approximate evaluation of integrals.

A sophisticated and original introduction to the philosophy of quantum mechanics from one of the world’s leading philosophers of physics In this book, Tim Maudlin, one of the world’s leading philosophers of physics, offers a sophisticated, original introduction to the philosophy of quantum mechanics. The briefest, clearest, and most refined account of his influential approach to the subject, the book will be invaluable to all students of philosophy and physics. Quantum mechanics holds a unique place in the history of physics. It has produced the most accurate predictions of any scientific theory, but, more astonishing, there has never been any agreement about what the theory implies about physical reality. Maudlin argues that the very term “quantum theory” is a misnomer. A proper physical theory should clearly describe what is there and what it does—yet standard textbooks present quantum mechanics as a predictive recipe in search of a physical theory. In contrast, Maudlin explores three proper theories that recover the quantum predictions: the indeterministic wavefunction collapse theory of Ghirardi, Rimini, and Weber; the deterministic particle theory of deBroglie and Bohm; and the conceptually challenging Many Worlds theory of Everett. Each offers a radically different proposal for the nature of physical reality, but Maudlin shows that none of them are what they are generally taken to be.
