Book Description
The classical theory of electromagnetism is entirely revised in this book by proposing a variant of Maxwell equations that allows solitonic solutions (photons). The Lagrangian is the standard one, but it is minimized on a constrained space that enforces the wave packets to follow the rules of geometrical optics. Exact solutions are explicitly shown; this opens a completely new perspective for the study of light wave phenomena. In the framework of general relativity, the equations are written in covariant form. A coupling with the metric is obtained through the Einstein equation, whose solutions are computed exactly in a lot of original situations. Finally, the explicit construction of elementary particles, consisting of rotating photons, is indicated. The results agree qualitatively and quantitatively with what it is actually observed. This opens the path to an understanding of the structure of matter and its properties, also aimed to provide a causal explanation to quantum phenomena.

Learning Electricity and Electronics with Advanced Educational Technology
Author: Michel Caillot
Publisher: Springer Science & Business Media
ISBN: 3662028786
Category : Technology & Engineering
Languages : en
Pages : 326
Book Description
The objective of the NATO Advanced Research Workshop "Learning electricity and electronics with advanced educational technology" was to bring together researchers coming from different domains. Electricity education is a domain where a lot of research has already been made. The first meeting on electricity teaching was organized in 1984 by R. Duit, W. Jung and C. von Rhoneck in Ludwigsburg (Germany). Since then, research has been going on and we can consider that the workshop was the successor of this first meeting. Our goal was not to organize a workshop grouping only people producing software in the field of electricity education or more generally in the field of physics education, even if this software was based on artificial intelligence techniques. On the contrary, we wanted this workshop to bring together researchers involved in the connection between cognitive science and the learning of a well defined domain such as electricity. So during the workshop, people doing research in physics education, cognitive psychology, and artificial intelligence had the opportunity to discuss and exchange. These proceedings reflect the different points of view. The main idea is that designing a learning environment needs the confrontation of different approaches. The proceedings are organized in five parts which reflect these different aspects.

Matter and Interactions II
Author: Ruth W. Chabay
Publisher:
ISBN:
Category : Science
Languages : en
Pages : 532
Book Description
A modern introduction to physics for advanced students, this work focuses on the atomic structure of the material plus the links between macroscopic and microscopic phenomena. Above all, readers learn how to explain complex physical processes using simple models. This second volume deals with the theory of electricity and magnetism, as well as physical optics as understood by the classical interaction between light and material. Electrostatics and currents are discussed in a simplified way using the electrical field and microscopic models.

Learning Electricity and Electronics with Advanced Educational Technology
Author: Michel Caillot
Publisher: Springer Science & Business Media
ISBN: 9783540566540
Category : Computers
Languages : en
Pages : 350
Book Description
This volume is based on a NATO Advanced Research Workshop in the Special Programme on Advanced Educational Technology. The objective of the workshop was to bring together researchers producing software in the field of electricity education, and more generally in physics education, and researchers involved in the connection between cognitive science andthe learning of a well defined domain such as electricity. The book is divided into five main parts: - New approaches to teaching electricity: research on the teaching of electricity has shown that traditional presentations should be questioned. - Analogies and models in electricity: teaching experiments based on different models of electricity are presented. - Contextualized electricity: a new field of research studies how adults who work with electricity and electronic devices represent electric phenomena and concepts. - Using computers in electricity teaching: studies show how computers can be used for assessing electricity knowledge and student models of electricity. -Design of learning environments: here interactive learning environments, some of them specially designed for practical work in electronics, are presented.

A Framework for K-12 Science Education
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309214459
Category : Education
Languages : en
Pages : 400
Book Description
Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.
