Modern Physics and Ancient Faith


Book Description

A considerable amount of public debate and media print has been devoted to the “war between science and religion.” In his accessible and eminently readable new book, Stephen M. Barr demonstrates that what is really at war with religion is not science itself, but a philosophy called scientific materialism. Modern Physics and Ancient Faith argues that the great discoveries of modern physics are more compatible with the central teachings of Christianity and Judaism about God, the cosmos, and the human soul than with the atheistic viewpoint of scientific materialism. Scientific materialism grew out of scientific discoveries made from the time of Copernicus up to the beginning of the twentieth century. These discoveries led many thoughtful people to the conclusion that the universe has no cause or purpose, that the human race is an accidental by-product of blind material forces, and that the ultimate reality is matter itself. Barr contends that the revolutionary discoveries of the twentieth century run counter to this line of thought. He uses five of these discoveries—the Big Bang theory, unified field theories, anthropic coincidences, Gödel’s Theorem in mathematics, and quantum theory—to cast serious doubt on the materialist’s view of the world and to give greater credence to Judeo-Christian claims about God and the universe. Written in clear language, Barr’s rigorous and fair text explains modern physics to general readers without oversimplification. Using the insights of modern physics, he reveals that modern scientific discoveries and religious faith are deeply consonant. Anyone with an interest in science and religion will find Modern Physics and Ancient Faith invaluable.




Quantum Physics


Book Description

This brilliantly innovative textbook is intended as a first introduction to quantum mechanics and its applications. Townsend's new text shuns the historical ordering that characterizes so-called Modern Physics textbooks and applies a truly modern approach to this subject, starting instead with contemporary single-photon and single-atom interference experiments. The text progresses naturally from a thorough introduction to wave mechanics through applications of quantum mechanics to solid-state, nuclear, and particle physics, thereby including most of the topics normally presented in a Modern Physics course. Examples of topics include blackbody radiation, Bose-Einstein condensation, the band-structure of solids and the silicon revolution, the curve of binding energy and nuclear fission and fusion, and the Standard Model of particle physics. Students can see in quantum mechanics a common thread that ties these topics into a coherent picture of how the world works, a picture that gives students confidence that quantum mechanics really works, too. The book also includes a chapter-length appendix on special relativity for the benefit of students who have not had a previous exposure to this subject.Translation into Chinese.

Advanced Modern Physics: Theoretical Foundations


Book Description

Our understanding of the physical world was revolutionized in the twentieth century — the era of “modern physics”. This book, aimed at the very best students, extends the coverage of the theoretical groundwork of today's physics presented in the previous volume: Introduction to Modern Physics: Theoretical Foundations (Vol. I). Typically, students have to wade through several courses to see many of these topics. The goal is to give them some idea of where they are going, and how things fit together, as they go along.The present book focuses on the following topics: reformulation of quantum mechanics, angular momentum, scattering theory, lagrangian field theory, symmetries, Feynman rules, quantum electrodynamics, including higher-order contributions, path integrals, and canonical transformations for quantum systems. Many problems are included that enhance and extend the coverage. The book assumes a mastery of the material in Vol. I, and the continued development of mathematical skills, including multivariable calculus and linear algebra. Several appendices provide important details, and any additional required mathematics. The reader should then find the text, together with the appendices and problems, to be self-contained. The aim is to cover the framework of modern theoretical physics in sufficient depth that things “make sense” to students, and, when finished, the reader should have an elementary working knowledge in the principal areas of theoretical physics of the twentieth century.







Newton And Modern Physics


Book Description

This book looks at how Newton's theories can be linked to modern day problems and solutions in physics. Newton created an abstract system of theorizing which has been applied to all aspects of the physical world, however he had difficulties in persuading his contemporaries of its unique merits. A detailed study of Newton's writings, published and unpublished, suggests that he had an almost archetypally powerful mode of thinking guaranteed to produce 'correct' results even in areas of physics where systematic study only began long after his time. Newton and Modern Physics investigates this phenomenon, looking at examples of where Newton's principles have relevance to modern day thinking — the study of Newton's work in both seventeenth century and present-day contexts helps to enhance our understanding of both.




Foundations of Modern Physics


Book Description

Nobel Laureate Steven Weinberg explains the foundations of modern physics in historical context for undergraduates and beyond.




How to Make an Apple Pie from Scratch


Book Description

NAMED A BEST SCIENCE BOOK OF 2021 BY KIRKUS * An acclaimed experimental physicist at CERN takes you on an exhilarating search for the most basic building blocks of our universe, and the dramatic quest to unlock their cosmic origins. "A fascinating exploration of how we learned what matter really is, and the journey matter takes from the Big Bang, through exploding stars, ultimately to you and me." (Sean Carroll) Carl Sagan once quipped, “If you wish to make an apple pie from scratch, you must first invent the universe.” But finding the ultimate recipe for apple pie means answering some big questions: What is matter really made of? How did it escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe? In How to Make an Apple Pie from Scratch, Harry Cliff—a University of Cambridge particle physicist and researcher on the Large Hadron Collider—sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the "Antimatter Factory," where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up). And he reveals what the latest data from the Large Hadron Collider may be telling us about the fundamental nature of matter. Along the way, Cliff illuminates the history of physics, chemistry, and astronomy that brought us to our present understanding—and misunderstandings—of the world, while offering readers a front-row seat to one of the most dramatic intellectual journeys human beings have ever embarked on. A transfixing deep dive into the origins of our world, How to Make an Apple Pie from Scratch examines not just the makeup of our universe, but the awe-inspiring, improbable fact that it exists at all.




On Theories


Book Description

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.
