Book Description
Important new insights into how various components and systems evolved Premised on the idea that one cannot know a science without knowing its history, History of Wireless offers a lively new treatment that introduces previously unacknowledged pioneers and developments, setting a new standard for understanding the evolution of this important technology. Starting with the background-magnetism, electricity, light, and Maxwell's Electromagnetic Theory-this book offers new insights into the initial theory and experimental exploration of wireless. In addition to the well-known contributions of Maxwell, Hertz, and Marconi, it examines work done by Heaviside, Tesla, and passionate amateurs such as the Kentucky melon farmer Nathan Stubblefield and the unsung hero Antonio Meucci. Looking at the story from mathematical, physics, technical, and other perspectives, the clearly written text describes the development of wireless within a vivid scientific milieu. History of Wireless also goes into other key areas, including: The work of J. C. Bose and J. A. Fleming German, Japanese, and Soviet contributions to physics and applications of electromagnetic oscillations and waves Wireless telegraphic and telephonic development and attempts to achieve transatlantic wireless communications Wireless telegraphy in South Africa in the early twentieth century Antenna development in Japan: past and present Soviet quasi-optics at near-mm and sub-mm wavelengths The evolution of electromagnetic waveguides The history of phased array antennas Augmenting the typical, Marconi-centered approach, History of Wireless fills in the conventionally accepted story with attention to more specific, less-known discoveries and individuals, and challenges traditional assumptions about the origins and growth of wireless. This allows for a more comprehensive understanding of how various components and systems evolved. Written in a clear tone with a broad scientific audience in mind, this exciting and thorough treatment is sure to become a classic in the field.

Book Description
Germany’s imaginative employment of transport aircraft in World War II produced as many innovations as Germany’s use of tanks. Indeed, like the tank, the transport aircraft was closely associated with the Blitzkrieg concept. This relationship was advantageous at the outset of the war, but it became dangerous as the war dragged on and German armies outran their surface supply lines in North Africa and Russia. Then ground commanders began to think of air transport as the means of supply. The history of this trend is one of the main themes of this study, which was first published in its English translation in 1961. Some of the questions embodied in this theme—How much air transport is enough? Under what conditions is an air-supply operation feasible? What are the prerequisites for a successful airlift to encircled ground forces? What are the advantages and limitations of the glider?—are as vital and controversial today as they were during World War II. Generalmajor a. D. Fritz Morzik, who began his military career as a non-commissioned officer in the German Air Service in World War I and ended it as Armed Forces Chief of Air Transport in World War II, is especially well-qualified to write the present study. His long career, spanning two world wars, and his experience with both civilian and military transport aircraft testify to the breadth of his practical knowledge.

Book Description
Long before the Arab Spring and its use of social media demonstrated the potent intersection between technology and revolution, the Mexican Revolution employed wireless technology in the form of radiotelegraphy and radio broadcasting to alter the course of the revolution and influence how political leaders reconstituted the government. Radio in Revolution, an innovative study of early radio technologies and the Mexican Revolution, examines the foundational relationship between electronic wireless technologies, single-party rule, and authoritarian practices in Mexican media. J. Justin Castro bridges the Porfiriato and the Mexican Revolution, discussing the technological continuities and change that set the stage for Lázaro Cárdenas's famous radio decree calling for the expropriation of foreign oil companies. Not only did the nascent development of radio technology represent a major component in government plans for nation and state building, its interplay with state power in Mexico also transformed it into a crucial component of public communication services, national cohesion, military operations, and intelligence gathering. Castro argues that the revolution had far-reaching ramifications for the development of radio and politics in Mexico and reveals how continued security concerns prompted the revolutionary victors to view radio as a threat even while they embraced it as an essential component of maintaining control.
