Book Description
A boy rides a bicycle down a dusty road. But in his mind, he envisions himself traveling at a speed beyond imagining, on a beam of light. This brilliant mind will one day offer up some of the most revolutionary ideas ever conceived. From a boy endlessly fascinated by the wonders around him, Albert Einstein ultimately grows into a man of genius recognized the world over for profoundly illuminating our understanding of the universe. Jennifer Berne and Vladimir Radunsky invite the reader to travel along with Einstein on a journey full of curiosity, laughter, and scientific discovery. Parents and children alike will appreciate this moving story of the powerful difference imagination can make in any life.

Book Description
This book presents the essential aspects of relativistic quantum field theory, with minimal use of mathematics. It covers the development of quantum field theory from the original quantization of electromagnetic field to the gauge field theory of interactions among quarks and leptons.Aimed at both scientists and non-specialists, it requires only some rudimentary knowledge of the Lagrangian and Hamiltonian formulation of Newtonian mechanics and a basic understanding of the special theory of relativity and quantum mechanics.

Book Description
This book traces the evolution of our understanding and utilization of light from classical antiquity and the early thoughts of Pythagoras to the present time. From the earliest recorded theories and experiments to the latest applications in photonic communication and computation, the ways in which light has been put to use are numerous and astounding. Indeed, some of the latest advances in light science are in fields that until recently belonged to the realm of science fiction. The author, writing for an audience of both students and other scientifically interested readers, describes fundamental investigations of the nature of light and ongoing methods to measure its speed as well as the emergence of the wave theory of light and the complementary photon theory. The importance of light in the theory of relativity is discussed as is the development of electrically-driven light sources and lasers. The information here covers the range o f weak single-photon light sources to super-high power lasers and synchrotron light sources. Many cutting-edge topics are also introduced, including entanglement-based quantum communication through optical fibers and free space, quantum teleportation, and quantum computing. The nature and use of "squeezed light" - e.g. for gravitational wave detection - is another fascinating excursion, as is the topic of fabricated metamaterials, as used to create invisibility cloaks. Here the reader also learns about the realization of extremely slow speed and time-reversed light. The theories, experiments, and applications described in this book are, whenever possible, derived from original references. The many annotated drawings and level of detail make clear the goals, procedures, and conclusions of the original investigators. Where they are required, all specialist terms and mathematical symbols are defined and explained. The final part of the book covers light expe riments in the free space of the cosmos, and also speculates about scenarios for the cosmological origins of light and the expected fate of the photon in a dying universe.

Book Description
Thomas Edison stunned America in 1879 by unveiling a world-changing invention--the light bulb--and then launching the electrification of America's cities. A decade later, despite having been an avowed opponent of the death penalty, Edison threw his laboratory resources and reputation behind the creation of a very different sort of device--the electric chair. Deftly exploring this startling chapter in American history, Edison & the Electric Chair delivers both a vivid portrait of a nation on the cusp of modernity and a provocative new examination of Edison himself. Edison championed the electric chair for reasons that remain controversial to this day. Was Edison genuinely concerned about the suffering of the condemned? Was he waging a campaign to smear his rival George Westinghouse's alternating current and boost his own system? Or was he warning the public of real dangers posed by the high-voltage alternating wires that looped above hundreds of America's streets? Plumbing the fascinating history of electricity, Mark Essig explores America's love of technology and its fascination with violent death, capturing an era when the public was mesmerized and terrified by an invisible force that produced blazing light, powered streetcars, carried telephone conversations--and killed.

Book Description
Roger and Carolyn Perron purchased the home of their dreams and eventual nightmares in December of 1970. The Arnold Estate, located just beyond the village of Harrisville, Rhode Island seemed the idyllic setting in which to raise a family. The couple unwittingly moved their five young daughters into the ancient and mysterious farmhouse. Secrets were kept and then revealed within a space shared by mortal and immortal alike. Time suddenly became irrelevant; fractured by spirits making their presence known then dispersing into the ether. The house is a portal to the past and a passage to the future. This is a sacred story of spiritual enlightenment, told some thirty years hence. The family is now somewhat less reticent to divulge a closely-guarded experience. Their odyssey is chronicled by the eldest sibling and is an unabridged account of a supernatural excursion. Ed and Lorraine Warren investigated this haunting in a futile attempt to intervene on their behalf. They consider the Perron family saga to be one of the most compelling and significant of a famously ghost-storied career as paranormal researchers. During a seance gone horribly wrong, they unleashed an unholy hostess; the spirit called Bathsheba; a God-forsaken soul. Perceiving herself to be the mistress of the house, she did not appreciate the competition. Carolyn had long been under siege; overt threats issued in the form of firea mother's greatest fear. It transformed the woman in unimaginable ways. After nearly a decade the family left a once beloved home behind though it will never leave them, as each remains haunted by a memory. This tale is an inspiring testament to the resilience of the human spirit on a pathway of discovery: an eternal journey for the living and the dead.
