Winter Lightning

From December 31, 1862, to January 2, 1863, one of the Civil War's bloodiest battles raged as more than 42,000 Union troops led by General William S. Rosecrans met 37,000 Confederates under General Braxton Bragg near the small town of Murfreesboro, Tennessee. The Battle of Stones River, which the Union declared as a victory, significantly boosted Union morale in the Western Theater. Stones River has received scant attention in comparison to other battles, such as Gettysburg, Shiloh, and Vicksburg, especially in the publication of tour guidebooks. Winter Lightening is the only battlefield guide to Stones River available in print. Designed as a step-by-step primer for visitors to the Stones River National Battlefield, it offers a comprehensive, "you are there" overview of the important events that took place during the battle. Winter Lightening follows a sequential series of twenty-one "stops" to guide the visitor through the battlefield over the exact routes used by both armies, offering informative details on what happened at key points along the way. The guide divides the battle into three segments: the west flank, the center, and the east flank. This approach allows visitors to follow the battle in its entirety or in any order they wish. Detailed maps and extensive primary material including commentary by commanders, letters, and other fascinating sources further enrich the visitor's experience. Matt Spruill is a retired U.S. Army colonel and formerly a Gettysburg Licensed Battlefield Guide. He is the author of Guide to the Battle of Chickamauga, Storming the Heights and Echoes of Thunder. Lee Spruill, a paramedic and fireman, is a major in the U.S. Army Reserve and has just returned from a tour of duty in Afghanistan.

Lightning: Physics and Effects is the first book that covers essentially all aspects of lightning, including lightning physics, lightning protection and the interaction of lightning with a variety of objects and systems as well as with the environment. It is written in a style that will be accessible to the technical non-expert and is addressed to anyone interested in lightning and its effects. This will include physicists, engineers working in the power, communications, computer and aviation industries, meteorologists, atmospheric chemists, foresters, ecologists, physicians working in the area of electrical trauma and architects. This comprehensive reference volume contains over 300 illustrations, 70 tables containing quantitative information and a bibliography of more than 6000 references.

This book highlights the essential theoretical and practical aspects of lightning, lightning protection, safety and education. Additionally, several auxiliary topics that are required to understand the core themes are also included. The main objective of the contents is to enlighten the scientists, researchers, engineers and social activists (including policy makers) in developing countries regarding the key information related to lightning and thunderstorms. A majority of developing countries are in tropics where the lightning characteristics are somewhat different from those in temperate regions. The housing structures and power/communication networks, and human behavioural patterns(that depends on socio-economic parameters) in these countries are also different from those in the developed world. As the existing books on similar themes address only those scenarios in developed countries, this book serves a vast spectrum of readership in developing world who seek knowledge in the principles of lightning and a practical guidance on lightning protection and safety education.

Ball lightning is an enigma. These luminous objects that appear occasionally during thunderstorms and can reach several meters in diameter have been a mystery to science for about 200 years. Despite several thousands of reported observations, their nature is still unknown. In this book, well documented cases of ball lightning are described and used to unravel some aspects of this mysterious form of atmospheric electricity. Throughout the book, the author discusses the various facets of the problem in an accessible but rigorous style, delivering a readable and informative text that will captivate the curious reader. He finally reaches the surprising conclusion that the solution to this puzzle may have been hidden in plain sight for many years. A foreword by Earle Williams, leading lightning researcher at MIT, introduces the book.

This book presents the first simultaneous detection of neutrons and positrons after a terrestrial gamma-ray flash (TGF), a highest-energy transient phenomenon on the earth, triggered by a lightning discharge, based on innovative ground-based observations made in the Hokuriku area of Japan. TGFs, known to be produced by lightning discharges since the 1990s, has been theoretically predicted to react with atmospheric nuclei via photonuclear reactions because they comprise high-energy photons of more than 10 MeV, but such photonuclear reactions by lightning discharges, which produce neutrons and unstable isotopes emitting positrons, were not observationally confirmed. The reactions and propagations of their products in the atmosphere are modeled with Monte Carlo simulations to quantitatively evaluate observations of TGFs, neutrons, and positrons at ground level. The successful comparison between observation and simulation is presented, and demonstrates that lightning discharges to trigger photonuclear reactions and to even produce isotopes in the atmosphere.
