This revised popular field guide describes in detail each of the more than 500 geysers in Yellowstone National Park. With updated information and a new foreword by park archivist Lee Whittlesey, Geysers of Yellowstone is both a reference work and a fine introduction to the nature of geyser activity for the newcomer to geothermal phenomena. A glossary of key terms is provided, along with a comprehensive appendix that discusses other geyser areas of the world. Detailed maps accompany each geyser basin described, and tables are provided for easy reference.
The Potentials About a Point Electrode and Apparent Resistivity Curves for a Two-, Three-, and Four-Layer Earth was first published in 1956. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
This publication will be useful to geophysicists, geologists, and others engaged in exploration for minerals by electrical methods, and may be used in theoretical studies of electrical prospecting. It makes available for the first time a comprehensive collection of 2268 master resistivity curves for a two-, three-, and four-layer earth. All previous collections of curves for Wenner electrode configuration are included, so the user will not need to refer elsewhere to complete his set of working curves. In addition, the basic potential data used in computing the curves is given in tables. Auxiliary tables are provided to reduce the graphic integration procedures to simple arithmetic. The integral in question occurs widely in solutions to Laplace's equation.
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.

An interdisciplinary approach to solar physics, as eighty-nine contributors trace the evolution of the Sun and provide a review of our current understanding of both its structure and its role in the origin and evolution of the solar system.
"The book is a treasure trove of tidbits describing how the world around us came about. . . . Things Maps Don't Tell Us actually communicates a great deal about the things maps can tell us if we care to look carefully underneath the printed symbols."—James E. Young, Cartographic Perspectives
