Paperback. Condición: New. Print on Demand. This book delves into the science of lightning, specifically exploring its impact on electrical circuits and the challenge it poses to the development of reliable railway signaling systems. The author, a pioneer in using rails as electrical conductors for automatic signaling, traces th…e history of electrical research and development, highlighting the fascinating tension between laboratory-based discoveries and the enduring mysteries of natural phenomena. He argues that while the electrical science has made great strides in the laboratory, the study of lightning has remained surprisingly stagnant since the days of Benjamin Franklin. Through detailed observations and experiments, the author meticulously examines the formation of thunderstorms, the vast electrical fields they generate, and the complex paths lightning takes as it discharges through the earth. He debunks common misconceptions about lightning protection, particularly those based on outdated Leyden jar experiments, and sheds light on the critical role of underground pipes, railway tracks, and other metallic conductors in shaping lightning's trajectory. By analyzing the history and the science, the book offers a comprehensive and insightful understanding of lightning's actions and its impact on electrical systems, paving the way for improved safety and efficiency in railway signaling and other technological applications. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
