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 zigzag theory, a solution that led to the discovery of a layer in the Earths upper atmosphere that bounces radio waves earthwardthe ionosphere.In Probing the Sky with Radio Waves, ChenPang 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 atmospheres constitution, the origin of atmospheric electricity, and how the sun and geomagnetism shape the Earths 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.
