Book Description
Methods of Historical Analysis in Electronic Media provides a foundation for historical research in electronic media by addressing the literature and the methods--traditional and the eclectic methods of scholarship as applied to electronic media. It is about history--broadcast electronic media history and history that has been broadcast, and also about the historiography, research written, and the research yet to be written. Divided into five parts, this book: *addresses the challenges in the application of the historical methods to broadcast history; *reviews the various methods appropriate for electronic-media research based on the nature of the object under study; *suggests new approaches to popular historical topics; *takes a broad topical look at history in broadcasting; and *provides a broad overview of what has been accomplished, a historian's challenges, and future research. Intended for students and researchers in broadcast history, Methods of Historical Analysis in Electronic Media provides an understanding of the qualitative methodological tools necessary for the study of electronic media history, and illustrates how to find primary sources for electronic media research.

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
Industrial methods, and industrially produced instruments, reagents and living organisms are central to research activities today. They play a key role in the homogenization and the diffusion of laboratory practices, thus in their transformation into a stable and unproblematic knowledge about the natural world. This book displays the - frequently invisible - role of industry in the construction of fundamental scientific knowledge through the examination of case studies taken from the history of nineteenth and the twentieth century physics, chemistry and biomedical sciences.

Book Description
As editor Kenneth E. Hendrickson, III, notes in his introduction: “Since the end of the nineteenth-century, industrialization has become a global phenomenon. After the relative completion of the advanced industrial economies of the West after 1945, patterns of rapid economic change invaded societies beyond western Europe, North America, the Commonwealth, and Japan.” In The Encyclopedia of the Industrial Revolution in World History contributors survey the Industrial Revolution as a world historical phenomenon rather than through the traditional lens of a development largely restricted to Western society. The Encyclopedia of the Industrial Revolution in World History is a three-volume work of over 1,000 entries on the rise and spread of the Industrial Revolution across the world. Entries comprise accessible but scholarly explorations of topics from the “aerospace industry” to “zaibatsu.” Contributor articles not only address topics of technology and technical innovation but emphasize the individual human and social experience of industrialization. Entries include generous selections of biographical figures and human communities, with articles on entrepreneurs, working men and women, families, and organizations. They also cover legal developments, disasters, and the environmental impact of the Industrial Revolution. Each entry also includes cross-references and a brief list of suggested readings to alert readers to more detailed information. The Encyclopedia of the Industrial Revolution in World History includes over 300 illustrations, as well as artfully selected, extended quotations from key primary sources, from Thomas Malthus’ “Essay on the Principal of Population” to Arthur Young’s look at Birmingham, England in 1791. This work is the perfect reference work for anyone conducting research in the areas of technology, business, economics, and history on a world historical scale.

Book Description
Discover (or rediscover) the fun and magic of building electronic circuits with thermatrons (vacuum tubes). This book has everything you need to know about the art and science of thermatron design and construction. It pulls together, in one easy to read book, thermatron types and characteristics, thermatron homebrew techniques, and how to design audio and RF triode and pentode circuits. The book is written primarily for radio amateurs (or audio equipment builders) that already understands basic electronics but have forgotten or never had the pleasure of working with hollow-state devices. The Second Edition includes over 50+ pages of new and revised material including a new chapter on thermatron oscillator design.
