Sundials: Their Theory and Construction - 1973

"Have you ever wanted to build a sundial or to understand how one works? Then you have probably been frustrated as you searched vainly for help. Most books on the subject are either rare out-of-print works published centuries ago and available only in highly specialized collections, or highly complicated treatises whose information is hidden behind frightening arrays of involved formulas. But now your search is over. This book is designed to meet sundialing needs at either the simple or the sophisticated level. Albert E. Waugh, for 40 years professor and administrator at the University of Connecticut, is an expert on the subject of sundials and their curious history. On the one hand he presents a rigorous appraisal of the science of sundials, including mathematical treatment and an explanation of the pertinent astronomical background; on the other hand, he presents simple and non-technical treatments such that several of the dials can be built by children!" - Sundials: Their Theory and Construction - Albert E. Waugh Published 1973, Dover Publications, Inc. New York Softcover. Approx 5.5x8.5in. 230pp. In good vintage condition.
