A major biography of Michael Faraday (1791-1867), one of the giants of 19th century science and discoverer of electricity who was at the centre of an extraordinary scientific renaissance in London. Faraday's life was truly inspirational. Son of a Yorkshire blacksmith who moved to London in 1789, he was a self-made, self-educated man whose public life was underpinned by his devotion to a minor Christian sect (the Sandemanians) and to his wife. He was also a fine writer and brilliant lecturer. This book is a passionate exploration of his life, work and times (he was a pioneering scientific all-rounder who also experimented with electromagnetism, techniques for preserving meat and fish, optical glass, the safety lamp, and the identification of iodine as a new element). It will also tell the story of the dawn of the modern scientific age and interweave Faraday's life with the groundbreaking work of the Royal Institution and other early scientists like Humphrey Davey, Charles Babbage, John Herschel and Mary Somerville.
An eye-opening history of the technology that harnessed electricity and powered the greatest scientific and technological advances of our time. What begin as a long-running dispute in biology, involving a dead frog's twitching leg, a scalpel, and a metal plate, would become an invention that transformed the history of the world: the battery. Science journalist Henry Schlesinger traces the history of this essential power source and demonstrates its impact on our lives, from Alessandro Volta's first copper-and-zinc model in 1800 to twenty-first-century technological breakthroughs. Schlesinger introduces the charlatans and geniuses, the paupers and magnates, who were attracted to the power of the battery.
As Charlton Heston put it: 'There's a temptingly simple definition of the epic film: it's the easiest kind of picture to make badly.' This book goes beyond that definition to show how the film epic has taken up one of the most ancient art-forms and propelled it into the modern world, covered in twentieth-century ambitions, anxieties, hopes and fantasies. This survey of historical epic films dealing with periods up to the end of the Dark Ages looks at epic form and discusses the films by historical period, showing how the cinema reworks history for the changing needs of its audience, much as the ancient mythographers did. The form's main aim has always been to entertain, and Derek Elley reminds us of the glee with which many epic films have worn their label, and of the sheer fun of the genre. He shows the many levels on which these films can work, from the most popular to the specialist, each providing a considerable source of enjoyment. For instance, spectacle, the genre's most characteristic trademark, is merely the cinema's own transformation of the literary epic's taste for the grandiose. Dramatically it can serve many purposes: as a resolution of personal tensions (the chariot race in Ben-Hur), of monotheism vs idolatry (Solomon and Sheba), or of the triumph of a religious code (The Ten Commandments). Although to many people Epic equals Hollywood, throughout the book Elley stresses debt to the Italian epics, which often explored areas of history with which Hollywood could never have found sympathy. Originally published 1984.

In the past several decades, the research on spin transport and magnetism has led to remarkable scientific and technological breakthroughs, including Albert Fert and Peter Gr nberg's Nobel Prize-winning discovery of giant magnetoresistance (GMR) in magnetic metallic multilayers. Handbook of Spin Transport and Magnetism provides a comprehensive, balanced account of the state of the art in the field known as spin electronics or spintronics. It reveals how key phenomena first discovered in one class of materials, such as spin injection in metals, have been revisited decades later in other materials systems, including silicon, organic semiconductors, carbon nanotubes, graphene, and carefully engineered nanostructures. The first section of the book offers a historical and personal perspective of the field written by Nobel Prize laureate Albert Fert. The second section addresses physical phenomena, such as GMR, in hybrid structures of ferromagnetic and normal metals. The third section discusses recent developments in spin-dependent tunneling, including magnetic tunnel junctions with ferroelectric barriers. In the fourth section, the contributors look at how to control spin and magnetism in semiconductors. In the fifth section, they examine phenomena typically found in nanostructures made from metals, superconductors, molecular magnets, carbon nanotubes, quantum dots, and graphene. The final section covers novel spin-based applications, including advanced magnetic sensors, nonvolatile magnetoresistive random access memory, and semiconductor spin-lasers. The techniques and materials of spintronics have rapidly evolved in recent years, leading to vast improvements in hard drive storage and magnetic sensing. With extensive cross-references between chapters, this seminal handbook provides a complete guide to spin transport and magnetism across various classes of materials and structures.

Electromagnetic scattering from complex objects has been an area of in-depth research for many years. A variety of solution methodologies have been developed and utilised for the solution of ever increasingly complex problems. Among these methodologies, the subject of impedance boundary conditions has interested the authors for some time. In short, impedance boundary conditions allow one to replace a complex structure with an appropriate impedance relationship between the electric and magnetic fields on the surface of the object. This simplifies the solution of the problem considerably, allowing one to ignore the complexity of the internal structure beneath the surface. This book examines impedance boundary conditions in electromagnetics. The introductory chapter provides a presentation of the role of the impedance boundary conditions in solving practical electromagnetic problems and some historical background. One of the main objectives of this book is to present a unified and thorough discussion of this important subject. A method based on a spectral domain approach is presented to derive the Higher Order Impedance Boundary Conditions (HOIBC). The method includes all of the existing approximate boundary conditions, such as the Standard Impedence Boundary Condition, the Tensor Impedence Boundary Condition and the Generalised Impedance Boundary Conditions, as special cases. The special domain approach is applicable to complex coatings and surface treatments as well as simple dielectric coatings. The spectral domain approach is employed to determine the appropriate boundary conditions for planar dielectric coatings, chiral coatings and corregated conductors. The accuracy of the proposal boundary conditions is discussed. The approach is then extended to include the effects of curvature and is applied to curved dielectric and chiral coatings. Numerical data is presented to critically assess the accuracy of the results obtained using various forms of the impedence boundary conditions. A number of appendices that provide more detail on some of the topics addressed in the main body of the book and a selective list of references directly related to the topics addressed in this book are also included.
This is the first book devoted to a systematic description of the
linear theory of piezoelectric shells and plates theory. The book
contains two parts. In the first part, the theories for
electroelastic thin-walled elements of arbitrary form with
different directions of preliminary polarization are presented in
an easy form for practical use. The approximate methods for
integrating the equations of piezoelectric shells and plates are
developed and applied for solving some engineering problems. In the
second part, the theory of piezoelectric shells and plates is
substantiated by the asymptotic method. The area of applicability
for different kinds of electroelastic shell theories is studied. A
new problem concerning the electroelastic phenomena at the edge of
a thin-walled element is raised and solved.
