How do you protect electrical systems from high energy electromagnetic pulses? This book completes the overview of systems and practices against EMPs from high altitude sources started with the previous "Protecting Electrical Equipment - Good Practices for preventing high altitude electromagnetic pulse impacts", including practical protection methods and means for evaluating their effectiveness.
An exploration of cutting-edge theories on the electromagnetic basis of consciousness • Details, in nontechnical terms, 12 credible theories, each published by prominent professionals with extensive scientific credentials, that describe how electromagnetic fields may be the basis for consciousness • Examines practical applications of electromagnetic-consciousness theory, including the use of contemporary brain stimulation devices to modify and enhance consciousness • Explores the work of William Köhler, Susan Pockett, Johnjoe McFadden, Rupert Sheldrake, Ervin Laszlo, William Tiller, Harold Saxton Burr, Sir Roger Penrose, Stuart Hameroff, Mari Jibu, Kunio Yasue, Karl Pribram, Alfred North Whitehead, and James Clerk Maxwell, as well as the author's own theories In this scientific exploration of the origin of consciousness, Shelli Renée Joye, Ph.D., explores 12 credible theories, each published by prominent professionals with extensive scientific credentials, that describe how electricity in the form of electromagnetic fields is the living consciousness that runs through the brain. Each of these theories supports the idea that the electromagnetic field itself is the basis of consciousness and that this source of consciousness peers out into the space-time universe through our human sensory systems, flowing with awareness throughout the bloodstream and nervous system. Following her exploration of electromagnetic-consciousness theories, Joye then examines practical applications, describing how electric fields might be manipulated and controlled to modify and enhance the operation of consciousness in the human brain. She explores the use of contemporary brain stimulation devices that offer benefits such as decreased addiction cravings and anxiety, reduced depression and chronic pain, enhanced mathematical abilities, accelerated learning, and greater insight during mindfulness meditation. Revealing the cutting edge of consciousness studies, Joye shows that consciousness is not an isolated function of the individual brain but is connected to the larger electromagnetic field that not only encompasses the entire physical universe but also is deeply involved in the creation of matter and the material world.
The story of two brilliant nineteenth-century scientists who discovered the electromagnetic field, laying the groundwork for the amazing technological and theoretical breakthroughs of the twentieth century Two of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by forty years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time. The authors, veteran science writers with special expertise in physics and engineering, have created a lively narrative that interweaves rich biographical detail from each man's life with clear explanations of their scientific accomplishments. Faraday was an autodidact, who overcame class prejudice and a lack of mathematical training to become renowned for his acute powers of experimental observation, technological skills, and prodigious scientific imagination. James Clerk Maxwell was highly regarded as one of the most brilliant mathematical physicists of the age. He made an enormous number of advances in his own right. But when he translated Faraday's ideas into mathematical language, thus creating field theory, this unified framework of electricity, magnetism and light became the basis for much of later, 20th-century physics. Faraday's and Maxwell's collaborative efforts gave rise to many of the technological innovations we take for granted today - from electric power generation to television, and much more. Told with panache, warmth, and clarity, this captivating story of their greatest work - in which each played an equal part - and their inspiring lives will bring new appreciation to these giants of science.
A refreshingly rich and encompassing perspective of our world, this examination demonstrates how, of the four forces of physical nature, it is electromagnetic force that activates nature as well as our bodies and brains. Arguing that electromagnetism plays an indispensable role in virtually all of modern technology, this book conveys how deeply embedded and intimately linked human beings are to earthly nature. Using lucid, understandable terms, it explains the electromagnetic workings of some of the core devices of modern technology—such as the transistor and radar—and shares a number of engaging vignettes about its discoverers and well as anecdotes drawn from the author's own experience.
Guru and Hiziroglu have produced an accessible and user-friendly text on electromagnetics that will appeal to both students and professors teaching this course. This lively book includes many worked examples and problems in every chapter, as well as chapter summaries and background revision material where appropriate. The book introduces undergraduate students to the basic concepts of electrostatic and magnetostatic fields, before moving on to cover Maxwell's equations, propagation, transmission and radiation. Chapters on the Finite Element and Finite Difference method, and a detailed appendix on the Smith chart are additional enhancements. MathCad code for many examples in the book and a comprehensive solutions set are available at www.cambridge.org/9780521830164.
An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
