Understanding Physics Using Mathematical Reasoning: A Modeling Approach for Practitioners and Researchers

by Andrzej Sokolowski

This book speaks about physics discoveries that intertwine mathematical reasoning, modeling, and scientific inquiry. It offers ways of bringing together the structural domain of mathematics and the content of physics in one coherent inquiry. Teaching and learning physics is challenging because students lack the skills to merge these learning paradigms. The purpose of this book is not only to improve access to the understanding of natural phenomena but also to inspire new ways of delivering and understanding the complex concepts of physics. To sustain physics education in college classrooms, authentic training that would help develop high school students’ skills of transcending function modeling techniques to reason scientifically is needed and this book aspires to offer such trainingThe book draws on current research in developing students’ mathematical reasoning. It identifies areas for advancements and proposes a conceptual framework that is tested in several case studies designed using that framework. Modeling Newton’s laws using limited case analysis, Modeling projectile motion using parametric equations and Enabling covariational reasoning in Einstein formula for the photoelectric effect represent some of these case studies. A wealth of conclusions that accompany these case studies, drawn from the realities of classroom teaching, is to help physics teachers and researchers adopt these ideas in practice.

Understanding Properties of Atoms, Molecules and Materials

by Pranab Sarkar Sankar Prasad Bhattacharyya

In a technology driven civilization the quest for new and smarter materials is everlasting. They are required as platforms for developing new technologies or for improving an already existing technology. The discovery of a new material is no longer chance driven or accidental, but is based on careful reasoning structured by deep understanding of the microconstituents of materials - the atoms and molecules in isolation or in an assembly. That requires fair amount of exposure to quantum and statistical mechanics. `Understanding Properties of Atoms, Molecules and Materials' is an effort (perhaps the first ever) to bring all the necessary theoretical ingredients and relevant physical information in a single volume. The book introduces the readers (first year graduates) or researchers in material chemistry/engineering to elementary quantum mechanics of atoms, molecules and solids and then goes on to make them acquainted with methods of statistical mechanics (classical as well as quantum) along with elementary principles of classical MD simulation. The basic concepts are introduced with clarity and illustrated with easy to grasp examples, thus preparing the readers for an exploration through the world of materials - the exotic and the mundane. The emphasis has been on the phenomena and what shapes them at the fundamental level. A comprehensive description of modern designing principles for materials with examples is a unique feature of the book. The highlights of the book are comprehensive introduction and analysis of Quantum states of atoms and molecules The translational symmetry and quantum states in periodic and amorphous solids Band structure and tuning Classical and quantum statistics with applications to ideal gases (photons, phonons and electrons, molecules) Quantum states in type-I and type-II superconductors (elementary theory included) Magnetic materials, materials with GMR and CMR Shape memory effects in alloys and materials 2D materials (graphene and graphene analogus) NLO and photovoltaic materials Hydrogen storage material for mitigating the looming energy crisis Quantum states in low and high band gap semiconductors Semimetals Designer materials, etc. The volume is designed and organized to create interest in the science of materials and the silent revolution that is redefining the goals and boundaries of materials science continuously.

Understanding Quantum Mechanics: The World According to Modern Quantum Foundations

by Detlef Dürr Dustin Lazarovici

This book discusses the physical and mathematical foundations of modern quantum mechanics and three realistic quantum theories that John Stuart Bell called "theories without observers" because they do not merely speak about measurements but develop an objective picture of the physical world. These are Bohmian mechanics, the GRW collapse theory, and the Many Worlds theory. The book is ideal to accompany or supplement a lecture course on quantum mechanics, but also suited for self-study, particularly for those who have completed such a course but are left puzzled by the question: "What does the mathematical formalism, which I have so laboriously learned and applied, actually tell us about nature?”

Understanding Quantum Science: A Concise Primer for Students of Chemistry, Biochemistry and Physics

by Steven M. Pascal

Students are naturally drawn to quantum science by the intriguing behaviors of small particles. However, they can also be intimidated by the lengthy and complicated treatment found in the classroom. Understanding Quantum Science: A Concise Primer for Students of Chemistry, Biochemistry, and Physics is a highly accessible book that offers students an opportunity to grasp the most fascinating of quantum topics, without the intimidation. To be sure, math is necessary, but it is introduced as needed and kept concise. The emphasis is on the science: a certain differential equation can be solved, and when it is, we find the energies that hydrogen atom electrons are allowed to have. Each concept is developed in this manner, keeping focus on how and why it arises, and on the intriguing consequences.This book provides a brief tour of some of the wonders of quantum science. But it is more than that, it is designed to be the most concise tour possible that truly explains how these wonders arise so that you can develop a working understanding of quantum concepts. If your goal is loftier and you wish to become a quantum specialist, the conceptual groundwork presented here, along with rationalization of the mathematics required, will position you well for higher level classes.

Understanding Race (Understanding Life)

by Rob DeSalle Ian Tattersall

The human species is very young, but in a short time it has acquired some striking, if biologically superficial, variations across the planet. As this book shows, however, none of those biological variations can be understood in terms of discrete races, which do not actually exist as definable entities. Starting with a consideration of evolution and the mechanisms of diversification in nature, this book moves to an examination of attitudes to human variation throughout history, showing that it was only with the advent of slavery that considerations of human variation became politicized. It then embarks on a consideration of how racial classifications have been applied to genomic studies, demonstrating how individualized genomics is a much more effective approach to clinical treatments. It also shows how racial stratification does nothing to help us understand the phenomenon of human variation, at either the genomic or physical levels.

Understanding Relativity: A Conceptual Journey Into Spacetime, Black Holes and Gravitational Waves (The Frontiers Collection)

by Wouter Schmitz

This book bridges the huge gap between popular science and mathematical treatments of Einstein's theories. It explains special and general relativity, gravity, black holes, and gravitational waves, also presenting current ideas about dark matter and dark energy. The explanations are entirely non-mathematical, using many color pictures and clear concepts. In this way, the reader is led to a much deeper understanding than any popular science book can provide. The author has written this book for everyone who wants to go beyond superficial descriptions of relativity's remarkable phenomena, but is not equipped to read the professional literature and complicated math behind the theory. By providing a complete description in terms of concepts and pictures, the book answers many questions about why the theory works as it does. For example, it explains why and how momentum and pressure are related to gravity; why and how mass causes spacetime to curve and how curvature tells objects how to move; it also reveals the origin of the ring seen around the first ever image of a black hole. Not least, the reader will learn in detail how gravitational waves are produced and measured. Since their conception, the theories of relativity have appealed to the public's imagination. Thanks to this book, readers now have the opportunity to convert their fascination with the topic to a deep understanding.

Understanding Scientific Theories of Origins: Cosmology, Geology, and Biology in Christian Perspective (BioLogos Books on Science and Christianity)

by John H. Walton Robert C. Bishop Larry L. Funck Stephen O. Moshier Raymond J. Lewis

The question of origins remains a stumbling block for many. But just as the Psalmist gained insight into God's character through the observation of nature, modern scientific study can deepen and enrich our vision of the Creator and our place in his creation. In this often contentious field Bishop, Funck, Lewis, Moshier, and Walton serve as our able guides. Based on over two decades of teaching origins together in the classroom, the authors present a textbook exploring mainstream scientific theories of origins in astronomy, cosmology, chemistry, geology, biology, physical anthropology, and genetics. While many authors engage origins from a Christian perspective, this is the first work offering a full-fledged discussion of the scientific narrative of origins from the Big Bang through humankind, from biblical and theological perspectives accessible to a lay audience. Topics include Principles of biblical interpretation Close readings of relevant Genesis texts A comprehensive Trinitarian doctrine of creation Cosmic origins The geologic history of Earth The origin of life on Earth The origin of species and diversity of life Human origins New creation and creation care Science education Rather than the familiar scenario where science and faith compete, this book seeks to diffuse tensions by taking the inspiration and authority of the Bible seriously while respecting and honoring God's revelation through creation. Understanding Scientific Theories of Origins gives the reader a detailed picture of the sciences of origins along with how they fit into the story of God's creative and redemptive action.

Understanding Surface and Thin Film Science

by Thomas M. Christensen

This book is a conceptual overview of surface and thin film science, providing a basic and straightforward understanding of the most common ideas and methods used in these fields. Fundamental scientific ideas, deposition methods and characterization methods are all examined. Relying on simple, conceptual models and figures, fundamental scientific ideas are introduced and then applied to surfaces and thin films in the first half of the book. Topics include vacuum and plasma environments, crystal structure, atomic motion, thermodynamics, electrical and magnetic properties, optical and thermal properties, and adsorbed atoms on surfaces. Common methods of gas phase thin film deposition are then introduced, starting with an overview of the film growth process and then a discussion of both physical and chemical vapor deposition methods. This is followed by an overview of a wide range of characterization techniques including imaging, structural, chemical, electrical, magnetic, optical, thermal, and mechanical techniques. Thin film science is a natural extension of surface science, especially as applications involve thinner and thinner films; distinct from other literature in the field, this book combines the two topics in a single volume. Simple, conceptual models and figures are used, supported by some mathematical expressions, to convey key ideas to students as well as practicing engineers, scientists, and technicians.

Understanding Sustainability Principles and ESG Policies: A Multidisciplinary Approach to Public and Corporate Responses to Climate Change

by Colin Read

This textbook explores sustainability, climate change, and the corporate responsibility movement from a broad array of perspectives, including the challenges, risks, and opportunities of ESG policies, energy and environmental science, economics and philosophy, and sound public and private sector management. There is no intergenerational issue that is more pressing than the challenge of sustainability and climate change. It is a concern that will only worsen within any reader’s lifetime, especially if we fail to act. At the same time, there is growing concern among corporations arising from the Environment, Social and Governance (ESG) paradigm that includes climate risk, future profits, and stakeholder expectations. Many of our leading institutions also increasingly acknowledge a responsibility for corporate decisions since the onset of the Industrial Revolution that plays no small role in bringing us to the existential precipice of our day. This book provides necessary tools of sufficient sophistication to address complex intergenerational issues, such as global warming, economic justice and fairness, appropriate intergenerational planning, sustainable finance, corporate risk management, and governance. The book offers a vital resource for students, shareholders, sustainability practitioners, agencies, and advocates interested in climate action, intergenerational accountability, and economic sustainability.
