This profound challenge to some of the most fundamental orthodoxies of modern nuclear physics grew from its author's discovery that, for all its success and sophistication, atomic theory has failed to provide a coherant explanation for the everyday phenomenon of electricity. M.L. Coleman located the source of the problem in the assumption that there are two different atomic particles carrying electrical charges, the electron with a negative charge and a position with a positive charge. The author boldly argues that there is, in fact, only one such particle, carrying both charges. He christens this single particle the "Eptron" A largely self educated scientist, Mr. Coleman remains a proud heir to the classical tradition stemming from Newton and clearly demonstrates how nuclear theory has failed to make sense of the basic phenomena of electricity, magnetism, and gravity which puzzled and inspired early physicists. The author reached his revolutionary conclusions by combining his mastery of both classical and modern theory with, in his own words, "A little common sense." Of course, a great deal of arduous research, creative experiment, and complex methematical thought to confirm his arguments. With rigor and clarity, he shows not only that the hypothesis of the Eptron is more elegant and economical than that of the seperate electrons and positrons, but also that it makes both direct and alternating current explicable for the first time in terms of nuclear physics. "All I have done," he explains with disarming honesty, "Is explain how electricity works." Eptron theory involves a radical new understanding not just of electricity, but of light itself. Through collisions with oneanother, Eptrons are transformed into photons and then back into Eptrons by the process of expansion and contraction which the eye perceives as light. While the higher reaches of his mathematics are addressed to the scientific community, the book as a whole is designed for laymen as well, and they will learn an enormous amount along the way, not just about Eptrons, but also about the history of Physics. "Demystifying Electricity" throws down a gauntlet to modern science that it cannot afford to ignore and reclaims nuclear theory in the name of common sense. "If my work is made available to young chemists, physicists, and electrical engineers," the author asserts with justifiable pride," I believe they will study it and find it correct."

The peripheral component interconnect (PCI) bus is the dominant bus system used to connect the different elements making up today's high-performance computer systems. Different PCI implementations have also been developed for such applications as telecommunications and embedded computing. If an application calls for high speed, high reliability, flexible configuration, and bus mastering, then PCI is the only logical bus choice. This book is an applications-oriented introduction to the PCI bus, with an emphasis on implementing PCI in a variety of computer architectures. Special attention is given to industrial and mission-critical applications of PCI bus.

Triathlon is among the world's most gear-intensive sports. The gear you select and how you use it can mean big results--or bigger disappointment. FASTER takes a scientific look at triathlon to see what truly makes you faster--and busts the myths and doublespeak that waste your money and race times. In this fascinating exploration of the forces at play in the swim-bike-run sport, astronautical engineer and triathlete Jim Gourley shows where to find free speed, speed on a budget, and the gear upgrades that are worth it. FASTER offers specific, science-based guidance on the fastest techniques and the most effective gear, answering questions like: Which wetsuit is best for me? What's the best way to draft a swimmer? Should I buy a lighter bike? Deep dish or disc wheels? Are lighter shoes faster? Who's right about running technique? Gourley reviews published studies in peer-reviewed journals to show what scientists have learned about swim drafting, pacing the bike leg, race strategy for short and long-course racing, and the fastest ways to handle transitions. FASTER will change how you think about your body, your gear, and the world around you. With science on your side, you'll make the smart calls that will make you a better, faster triathlete.

What is sustainability? Much has been said about the terms ‘sustainability’ and ‘sustainable development’ over the last few decades, but they have become buried under academic jargon. This book is one of the first that aims to demystify sustainability so that the layperson can understand the key issues, questions and values involved. Accessible and engaging, the book examines the ‘old’ sustainability of the past and looks to the future, considering how economic, ecological and social sustainability should be defined if we are to solve the entwined environmental, economic and social crises. It considers if meaningful sustainability is the same as a ‘sustainable development’ based on endless growth, examining the difficult but central issues of overpopulation and overconsumption that drive unsustainability. The book also explores the central role played by society’s worldview and ethics, along with humanity’s most dangerous characteristic – denial. Finally, it looks to the future, discussing the ‘appropriate’ technology needed for sustainability, and suggesting nine key solutions. This book provides a much-needed comprehensive discussion of what sustainability means for students, policy makers and all those interested in a sustainable future.

Foundational and accessible, this book equips pre-service and practicing teachers with the knowledge, understanding, tools, and resources they need to help students in grades 4–12 develop reading proficiencies in four core academic subjects—literature, history, science, and mathematics. Applying a disciplinary literacy approach, Fang describes the verbal and visual resources, expert strategies, inquiry skills, and habits of mind that students must learn in order to read carefully, critically, purposefully, and with an informed skepticism across genres and content areas. He also shows how teachers can promote language learning and reading/literacy development at the same time that they engage students in content area learning. With informative synthesis and research-based recommendations in every chapter, this text prepares teachers to help students develop discipline-specific, as well as discipline-relevant, discursive insights, literacy strategies, and ways of thinking, reasoning, and inquiring that are essential to productive learning across academic subjects. It also provides teacher educators with approaches and strategies for helping teacher candidates develop expertise in academic reading instruction. In so doing, the book demystifies academic reading, revealing what it takes for students to read increasingly complex academic texts with confidence and understanding and for teachers to develop expertise that promotes disciplinary literacy. This state-of-the-art text is ideal for courses on reading/literacy methods and academic literacy and eminently relevant to all educators who want their students to become thoughtful readers and powerful learners

In classical Newtonian mechanics, equations and formulas never change form. The same thing cannot be said about the equations and formulas of electromagnetic theory, which often change form when converted from one system of units to another. This work aims to provide the technical professional with an explanation of how to convert electromagnetic equations from one system of units to another. The level is geared to professionals and students who have a sound understanding of electricity and magnetism. It explains all five systems of electromagnetic units in depth, four connected to the centimetre-gram-second (cgs) system of mechanical units and one connected to the metre-kilogram-second (mks) system of mechanical units - commonly called the Systeme International.
