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.
