Sundials: their theory and construction / Albert E. Waugh. - xii, 228 pages : illustrations ; 22 cm
Includes bibliographical references (pages 225-226) and index.
Historical sketch -- Kinds of time -- The noon mark -- Equatorial sundial -- Horizontal sundial -- Vertical direct south dials -- Vertical direct north dial -- Vertical direct east and west dials -- Polar dials -- Vertical declining dials -- Direct reclining or inclining dials -- Dials which both decline and recline -- Analemmatic dials -- Reflected ceiling dials -- Dial furniture -- Portable dials -- Armillary sphere -- Memorial dials -- Practical hints on dialling.
Have you ever wanted to build a sundial or to understand how on 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 higly 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 prodessor and administrator at the University of Connectiut, 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 the 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. The subject matter is arranged in 19 chapters, each covering a different aspect of dialling science. All the common types of dials are covered, but the reader can also learn about analemmatic dials, polar dials, equatorial dials, portable dials, memorial dials, armillary spheres, reflected ceiling dials, cross dials and old-fashioned noo makrs. THere are also sections on dial furniture, mottoes, the actual laying out of a dial, the equation of time, finding time in other cities, how to find the meridian, how to find time by moonlight - even how to estimate time from the length for the length of one's own shadow! Directions are given for designing dials for any part of the country, or any place in the world. The author has designed many dials, and his text is filled with helpful hints based on his own personal experience. There are over 100 illustrations, charts and tables, followed by an appendix which is filled with material which reduces or eliminates the need for calculation on the part of the reader. (Back cover).
