This book delves into the fascinating world of vacuum tubes, those enigmatic glass vessels containing rarefied gases that captivated scientists in the late 19th and early 20th centuries. The author, a keen observer of these phenomena, takes a unique approach, contrasting the prevailing methods of studying vacuum tubes using high voltage and large currents with his own, more nuanced methodology. He advocates for employing lower voltages and currents, enabling a clearer view of the fundamental processes at play. The book delves into the intricate patterns of light, known as bands, formed within vacuum tubes when subjected to electric currents. These patterns are shown to be influenced by the presence of solid objects within the tube, the composition of the gas, and the intensity of the current. The author further explores the behavior of these bands under the influence of magnetic fields, providing insightful observations on the separation of electric currents in the presence of magnetic forces. The author's meticulous experiments offer a fresh perspective on the nature of electrical currents in both vacuum tubes and other conductors. Through careful examination and analysis, he raises thought-provoking questions about the role of the glass in the formation of light bands, the true nature of resistance in conductors, and the very essence of electric current propagation. This book serves as a valuable resource for anyone seeking to unravel the mysteries of vacuum tubes and their intriguing applications.
