This book reflects on recent advances in the understanding of percolation systems to present a wide range of transport phenomena in inhomogeneous disordered systems. Further developments in the theory of macroscopically inhomogeneous media are also addressed. These developments include galvano-electric, thermoelectric, elastic properties, 1/f noise and higher current momenta, Anderson localization, and harmonic generation in composites in the vicinity of the percolation threshold. The book describes how one can find effective characteristics, such as conductivity, dielectric permittivity, magnetic permeability, with knowledge of the distribution of different components constituting an inhomogeneous medium. Considered are a wide range of recent studies dedicated to the elucidation of physical properties of macroscopically disordered systems. Aimed at researchers and advanced students, it contains a straightforward set of useful tools which will allow the reader to derive the basic physical properties of complicated systems together with their corresponding qualitative characteristics and functional dependencies.
The focus of the present work is nonrelativistic and relativistic quantum mechanics with standard applications to the hydrogen atom. The author has aimed at presenting quantum mechanics in a comprehensive yet accessible for mathematicians and other non-physicists. The genesis of quantum mechanics, its applications to basic quantum phenomena, and detailed explanations of the corresponding mathematical methods are presented. The exposition is formalized (whenever possible) on the basis of the coupled Schroedinger, Dirac and Maxwell equations. Aimed at upper graduate and graduate students in mathematical and physical science studies.
Energy and power are fundamental concepts in electromagnetism and circuit theory, as well as in optics, signal processing, power engineering, electrical machines, and power electronics. However, in crossing the disciplinary borders, we encounter understanding difficulties due to (1) the many possible mathematical representations of the same physical objects, and (2) the many possible physical interpretations of the same mathematical entities. The monograph proposes a quantum and a relativistic approach to electromagnetic power theory that is based on recent advances in physics and mathematics. The book takes a fresh look at old debates related to the significance of the Poynting theorem and the interpretation of reactive power. Reformulated in the mathematical language of geometric algebra, the new expression of electromagnetic power reflects the laws of conservation of energy-momentum in fields and circuits. The monograph offers a mathematically consistent and a physically coherent interpretation of the power concept and of the mechanism of power transmission at the subatomic (mesoscopic) level. The monograph proves (paraphrasing Heaviside) that there is no finality in the development of a vibrant discipline: power theory.
“A perceptive and gripping biography” of the enigmatic British explorer, photographer, and author of Arabian Sands (Daily Mail, UK). Wilfred Thesiger, the last of the great gentlemen explorer-adventurers, journeyed for sixty years to some of the remotest, most dangerous places on earth, from the mountains of western Asia to the marshes of Iraq. The author of Arabian Sands, The Marsh Arabs and The Life of my Choice, he was a legend in his own lifetime. Yet his character and motivations have remained an intriguing enigma. In this authorized biography—written with Thesiger’s support before he died in 2003 and with unique access to the rich Thesiger archive—Alexander Maitland investigates this fascinating figure’s family influences, his wartime experiences, his philosophy as a hunter and conservationist, his writing and photography, his friendships with Arabs and Africans amongst whom he lived, and his now-acknowledged homosexuality.

In this monograph, the authors present their recently developed theory of electromagnetic interactions. This neoclassical approach extends the classical electromagnetic theory down to atomic scales and allows the explanation of various non-classical phenomena in the same framework. While the classical Maxwell–Lorentz electromagnetism theory succeeds in describing the physical reality at macroscopic scales, it struggles at atomic scales. Here, quantum mechanics traditionally takes over to describe non-classical phenomena such as the hydrogen spectrum and de Broglie waves. By means of modifying the classical theory, the approach presented here is able to consistently explain quantum-mechanical effects, and while similar to quantum mechanics in some respects, this neoclassical theory also differs markedly from it. In particular, the newly developed framework omits probabilistic interpretations of the wave function and features a new fundamental spatial scale which, at the size of the free electron, is much larger than the classical electron radius and is relevant to plasmonics and emission physics. This book will appeal to researchers interested in advanced aspects of electromagnetic theory. Treating the classical approach in detail, including non-relativistic aspects and the Lagrangian framework, and comparing the neoclassical theory with quantum mechanics and the de Broglie–Bohm theory, this work is completely self-contained.
The Victorians were obsessed with the empirical but were frequently frustrated by the sizeable gaps in their understanding of the world around them. This study examines how literature and popular culture adopted the emerging language of physics to explain the unknown or ‘imponderable’.
The focus of this book lies at the meeting point of electromagnetic waveguides and photonic crystals. Although these are both widely studied topics, they have been kept apart until recently. The purpose of the first edition of this book was to give state-of-the-art theoretical and numerical viewpoints about exotic fibres which use “photonic crystal effects” and consequently exhibit some remarkable properties.Since that first edition, photonic crystal fibres have become an important and effective optical device. In this second edition, the description of the theoretical and numerical tools used to study these fibres is enhanced, whilst up-to-date information about the properties, applications and fabrication of these fibres is added./a
Mormonism is the unofficial name for The Church of Jesus Christ of Latter-Day Saints, which originated in the early 1800s. Mormonism refers to the doctrines taught by Joseph Smith, doctrines that are believed to be original gospel preached by Jesus Christ. The Mormons oppose abortion, homosexuality, unmarried sexual acts, pornography, gambling, tobacco, consuming alcohol, tea, coffee, and the use of drugs. Despite its relatively young age, the Mormon Church continues to grow, and today it contains about 13 million members. The A to Z of Mormonism relates the history of the Mormon church through a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on crucial persons, organizations, churches, beliefs, and events. Clearing up many of the misconceptions held about Mormonism and its members, this is an essential reference.
Why do smokers claim that the first cigarette of the day is the best? What is the biological basis behind some heavy drinkers' belief that the "hair-of-the-dog" method alleviates the effects of a hangover? Why does marijuana seem to affect ones problem-solving capacity? Intoxicating Minds is, in the author's words, "a grand excavation of drug myth." Neither extolling nor condemning drug use, it is a story of scientific and artistic achievement, war and greed, empires and religions, and lessons for the future. Ciaran Regan looks at each class of drugs, describing the historical evolution of their use, explaining how they work within the brain's neurophysiology, and outlining the basic pharmacology of those substances. From a consideration of the effect of stimulants, such as caffeine and nicotine, and the reasons and consequences of their sudden popularity in the seventeenth century, the book moves to a discussion of more modern stimulants, such as cocaine and ecstasy. In addition, Regan explains how we process memory, the nature of thought disorders, and therapies for treating depression and schizophrenia. Regan then considers psychedelic drugs and their perceived mystical properties and traces the history of placebos to ancient civilizations. Finally, Intoxicating Minds considers the physical consequences of our co-evolution with drugs -- how they have altered our very being -- and offers a glimpse of the brave new world of drug therapies.

The book is devoted to several topical questions in modern mathematical and theoretical physics, astrophysics, geophysics, and cosmology that remain unsolved within the framework of the standard approaches. To them, one can attribute unexplained properties of the magnetic fields of stars and planets, puzzles of the Earth's atmosphere, the phenomenon of ball lightning, the problem of a qualitative description for nuclear forces and their well-known property of saturation, enigmatic properties of spiral galaxies, the problem of the cosmological singularity, mysteries of the dark matter and dark energy, amongst others. To find theoretical ways for understanding such phenomena, new nonlinear generalizations of the classical field theories and advanced methods to solve nonlinear equations arising in them are studied and presented in this book.
From the beloved author of the No. 1 Ladies' Detective Agency series comes a new short story collection: half spy stories, half tales of revenge, all highlight the kinder, funnier, and gentler side of espionage and retribution. In this dual collection of short stories, Alexander McCall Smith brings his trademark humor and warmth to inventive tales of spying and vengeance. In one story, a spy dropped deep into enemy territory manages to disguise himself--quite convincingly--as a nun. In another, an invitation to join the Vatican Secret Service sends a prospective operative down a rabbit hole of controversy and confusion. A third story finds an author, on the brink of public ruin, seeing the error of his ways after an act of kindness saves the day. A keen observer of humanity imbued with a sparkling imagination, Alexander McCall Smith illustrates throughout that transparency is paramount and forgiveness is restorative. With surprising insight and a healthy helping of humor, these stories remind us that, in the end, the high road is often the better one for all involved.
A panorama of ideas about nationality and culture, Arts and the Nation arose from the conviction that Scotland can never be really democratic until it gives the arts the priority of place and attention they demand. This book is a fresh take on subjects new and old, with multifaceted ideas of nationality and culture. Those featured include: William Dunbar, Duncan Ban MacIntyre and Elizabeth Melville are read alongside international authors such as Wole Soyinka and Edward Dorn. J.D. Fergusson, Joan Eardley and John Bellany are considered with American Alice Neel and the art of the ancient Celts. Composers like John Blackwood McEwen, Cecil Coles and Helen Hopekirk are introduced, amongst discussions of education, politics, social priorities, the mass media and different genres of writing. What was the real reason Robert Louis Stevenson dedicated his dark masterpiece to his cousin Katharine de Mattos? Why was Katharine's own tale of duality published under a pseudonym? When Fanny Stevenson 'stole' another story idea from Katharine, why did RLS explode with Hydelike rage at the cousin for whom he had once been 'the one that loves you – Jekyll, and not Hyde'? Featuring the full text of Katharine's tale of duality, Fanny's stolen story and another tale revealing Katharine's grief at losing her cousin's love forever, Mrs Jekyll & Cousin Hyde sheds new light on one of the greatest Victorian authors.

Summary of The God Equation Chapter 1: The same year Galileo Galilei died a broken man in his prison cell, another legend was born in London. For Kaku, Isaac Newton is the greatest scientist who has ever lived, and the modern dream of a unified theory began with him. At a time when the church had taught only two laws–on Earth and in the heavens–Newton’s idea proposed a unification that encompassed both. The results of his experiments allowed him to conclude that terrestrial and heavenly physics work the same, opening the world’s eyes to the concept of forces. Another remarkable characteristic of Newton’s laws was its symmetry. An equation is said to be symmetric when it stays invariant even after its parts are rearranged. Newton’s laws allowed for science to advance at unimaginable levels, and his masterpiece, Principia, is considered one of the field’s greatest scriptures. Decades after Newton came Michael Faraday and James Clerk Maxwell, who unified the concepts of electricity and magnetism, laying the foundations of electromagnetism. Faraday discovered the existence of magnetic fields, which, since then, have been used to express all known forces in the universe. His work laid the foundation for Maxwell’s equations who made astonishing developments in physics. In 1886, Heinrich Hertz achieved a scientific milestone using Maxwell’s equations and ...

This text discusses electromagnetics from the view of operator theory, in a manner more commonly seen in textbooks of quantum mechanics. It includes a self-contained introduction to operator theory, presenting definitions and theorems, plus proofs of the theorems when these are simple or enlightening.
This textbook explains the fundamental processes involved in the interaction of electromagnetic radiation with matter. It leads students from a general discussion of electrodynamics, forming the mathematical foundation for the Maxwell equations, to key results such as the Fresnel equations, Snell’s law, and the Brewster angle, deriving along the way the equations for accelerated charges and discussing dipole radiation, Bremsstrahlung and synchrotron radiation. By considering more and more interacting particles, the book advances its treatment of the subject, approaching the solid-state regime using both classical and quantum mechanical approaches to describe interaction paths with electromagnetic radiation. Finally, specific interactions of laser radiation with matter are explained such as ultrafast, coherent, and selective interaction. With an emphasis on achieving an intuitive grasp of the basic physics underlying common laser technology, this textbook is ideal for graduate students seeking both a better fundamental and applied understanding of laser–matter interaction.
