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 Eartha€™s upper atmosphere that bounces radio waves earthwarda€”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 atmospherea€™s constitution, the origin of atmospheric electricity, and how the sun and geomagnetism shape the Eartha€™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.... and the techniques for doing so.11 The first person to examine long-range radio-wave propagation was a typical Cambridge wrangler. ... a€œpropagation of electric waves under the influence of conducting wires and conducting or dielectric bodiesa€: a€œelectric resonance of linear ...
