Book Description
In a series of concise, thought-provoking chapters the authors summarize and make accessible the latest scholarship on the middle years of the Great War 1915 and 1916 and cover fundamental issues that are rarely explored outside the specialist journals. Their work is an important contribution to advancing understanding of Britains role in the war, and it will be essential reading for anyone who is keen to keep up with the fresh research and original interpretation that is transforming our insight into the impact of the global conflict. The principal battles and campaigns are reconsidered from a new perspective, but so are more general topics such as military leadership, the discord between Britains politicians and generals, conscientious objection and the part played by the Indian Army. The longer-term effects of the war are also considered facial reconstruction, developments in communication, female support for men on active service, grief and bereavement, the challenge to religious belief, battlefield art, and the surviving vestiges of the war. Peter Liddle and his fellow contributors have compiled a volume that will come to be seen as a landmark in the field.

Book Description
A comprehensive and fascinating account of electrical and electronics history Much of the infrastructure of today's industrialized world arose in the period from the outbreak of World War I to the conclusion of World War II. It was during these years that the capabilities of traditional electrical engineering—generators, power transmission, motors, electric lighting and heating, home appliances, and so on—became ubiquitous. Even more importantly, it was during this time that a new type of electrical engineering—electronics—emerged. Because of its applications in communications (both wire-based and wireless), entertainment (notably radio, the phonograph, and sound movies), industry, science and medicine, and the military, the electronics industry became a major part of the economy. Dawn of the Electronic Age?explores how this engineering knowledge and its main applications developed in various scientific, economic, and social contexts, and explains how each was profoundly affected by electrical technologies. It takes an international perspective and a narrative approach, unfolding the story chronologically. Though a scholarly study (with sources of information given in endnotes for engineers and historians of science and technology), the book is intended for the general public.?Ultimately, it tells the story of the development of a new realm of engineering and its widespread applications during the remarkable and tragic period of two world wars and the decades in between.

Book Description
Communications: An international history of the formative years traces the evolution of communications from 500 BC, when fire beacons were used for signalling, to the 1940s, when high definition television systems were developed for the entertainment, education and enlightenment of society. The book does not simply provide a chronicle of dates and events, nor is it a descriptive catalogue of devices and systems. Rather, it discusses the essential factors - technical, political, social, economic and general - that enabled the evolution of modern communications. The author has taken a contextual approach to show the influence of one discipline upon another, and the unfolding story has been widely illustrated with contemporary quotations, allowing the progress of communications to be seen from the perspective of the times and not from the standpoint of a later generation.

Book Description
Although the product of a self-proclaimed consensus politics, the British Empire was always based on communications supremacy and the knowledge of the atmosphere. Using the metaphor of a thread of five pieces representing the categories science, industry, government, the military, and the education, this is the first book to study the relations between wireless and Empire throughout the interwar period. It is also the first to make full use of the abundant archive material and rich sources existing in Britain and the Dominions. The book examines the evolving connection between the development of imperial radio communications and atmospheric physics; the expansion and strength of the British radio industry and its relationship with the elucidation of the ionosphere; and the different extent to which Australia, Canada and New Zealand managed to emulate the British model of radio R&D in the interwar years. The book ends with a highly original and provocative epilogue: 'The realist interpretation of the atmosphere'.

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
Sonar to Quartz Clock examines how the unapplied phenomenon of piezoelectricity became applied for technologies such as sonar, crystal frequency control, the quartz clock, and how its research has consequently changed during WWI and the interwar period. It aims at reconstructing, for the first time, the fascinating history of the inventions and the development of these highly important technologies, which are still in extensive use, and which were crucial for the electronic revolution, arguably the most important technological developments of the twentieth century. On this basis, this book suggests a better and more nuanced understanding of the relationships between modern science and technology and the process of development and innovation of science-based technologies. It examines in particular the mutual transfer and transformation of knowledge between them including the way physics becomes practically applicable, the way applications and societal interests shape technology and science, and the differences and similarities between scientific and technological research. The book presents an in-depth analysis of the scientific and technological research and development in the field, and of the evolution of their experimental, theoretical, and technical aspects within their social military and commercial contexts. It offers an integrative history of science and technology, needed to better comprehend their interactions and evolution but rare in current historiography. This book will appeal to historians of science and technology, sociologists of science and generally scientists and engineers studying or working with piezoelectricity, ultrasound devices, and crystal frequency control.
