This book offers a readable narrative of the science and technology of early radio combined with sociological and economic analysis of how radio changed our lives. Originally published in 1985. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

A vital instrument of power, telecommunications is and has always been a political technology. In this book, Headrick examines the political history of telecommunications from the mid-nineteenth century to the end of World War II. He argues that this technology gave society new options. In times of peace, the telegraph and radio were, as many predicted, instruments of peace; in times of tension, they became instruments of politics, tools for rival interests, and weapons of war. Writing in a lively, accessible style, Headrick illuminates the political aspects of information technology, showing how in both World Wars, the use of radio led to a shadowy war of disinformation, cryptography, and communications intelligence, with decisive consequences.

By the late nineteenth century, engineers and experimental scientists generally knew how radio waves behaved, and by 1901 scientists were able to manipulate them to transmit messages across long distances. What no one could understand, however, was why radio waves followed the curvature of the Earth. Theorists puzzled over this for nearly twenty years before physicists confirmed the zig-zag theory, a solution that led to the discovery of a layer in the Earth’s upper atmosphere that bounces radio waves earthward—the ionosphere. In Probing the Sky with Radio Waves, Chen-Pang Yeang documents this monumental discovery and the advances in radio ionospheric propagation research that occurred in its aftermath. Yeang illustrates how the discovery of the ionosphere transformed atmospheric science from what had been primarily an observational endeavor into an experimental science. It also gave researchers a host of new theories, experiments, and instruments with which to better understand the atmosphere’s constitution, the origin of atmospheric electricity, and how the sun and geomagnetism shape the Earth’s atmosphere. This book will be warmly welcomed by scholars of astronomy, atmospheric science, geoscience, military and institutional history, and the history and philosophy of science and technology, as well as by radio amateurs and electrical engineers interested in historical perspectives on their craft.

The articles in this first volume of ARCHIMEDES explicitly and intentionally cross boundaries between science and technology, and they also illuminate one another. The first three contributions concern optics and industry in 19th century Germany; the fourth concerns electric standards in Germany during the same period; the last essay in the volume examines a curious development in the early history of wireless signalling that took place in England, and that has much to say about the establishment and enforcement of standard methods in a rapidly-developing technology that emerged out of a scientific effect. Historical work over the last few decades has shown that technology cannot be characterized simply, or even usually, as applied science. The beliefs, the devices, and the natural objects that are created or discovered by scientists, often play altogether minor roles in the construction of technologies. Taking this realization as a given, the essays in Scientific Credibility and Technical Standards effectively argue that we must now seek to go beyond it; we must also begin to think carefully about the role that science actually did play when it was explicitly deployed by technologists.

Modern wireless communications hardware is underpinned by RF and microwave design techniques. This insightful book contains a wealth of circuit layouts, design tips, and practical measurement techniques for building and testing practical gigahertz systems. The book covers everything you need to know to design, build, and test a high-frequency circuit. Microstrip components are discussed, including tricks for extracting good performance from cheap materials. Connectors and cables are also described, as are discrete passive components, antennas, low-noise amplifiers, oscillators, and frequency synthesizers. Practical measurement techniques are presented in detail, including the use of network analyzers, sampling oscilloscopes, spectrum analyzers, and noise figure meters. Throughout the focus is practical, and many worked examples and design projects are included. There is also a CD-ROM that contains a variety of design and analysis programs. The book is packed with indispensable information for students taking courses on RF or microwave circuits and for practising engineers.

Communication plays a vital and unique role in society-often blamed for problems when it breaks down and at the same time heralded as a panacea for human relations. A sweeping history of communication, Speaking Into the Air illuminates our expectations of communication as both historically specific and a fundamental knot in Western thought. "This is a most interesting and thought-provoking book. . . . Peters maintains that communication is ultimately unthinkable apart from the task of establishing a kingdom in which people can live together peacefully. Given our condition as mortals, communication remains not primarily a problem of technology, but of power, ethics and art." —Antony Anderson, New Scientist "Guaranteed to alter your thinking about communication. . . . Original, erudite, and beautifully written, this book is a gem." —Kirkus Reviews "Peters writes to reclaim the notion of authenticity in a media-saturated world. It's this ultimate concern that renders his book a brave, colorful exploration of the hydra-headed problems presented by a rapid-fire popular culture." —Publishers Weekly What we have here is a failure-to-communicate book. Funny thing is, it communicates beautifully. . . . Speaking Into the Air delivers what superb serious books always do-hours of intellectual challenge as one absorbs the gradually unfolding vision of an erudite, creative author." —Carlin Romano, Philadelphia Inquirer

“The gold standard for Tesla biography.”—Science “Superb.”—Nature The definitive account of Tesla's life and work Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the twentieth century. His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft. Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an "idealist" inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion. This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.
