{ "item_title" : "Azimuth", "item_author" : [" Joseph Edgar Craig", "Loci "], "item_description" : "Azimuth is a comprehensive treatise on the subject of astronomy, written by Joseph Edgar Craig and originally published in 1887. The book provides a detailed study of the astronomical triangle and the effect that errors in data can have on the accuracy of calculations related to azimuth. The book is divided into several chapters, each of which covers a specific aspect of azimuth and related topics. The first chapter provides an overview of the principles of astronomy and introduces the concept of azimuth. The second chapter delves into the mathematical calculations involved in determining azimuth, including the use of logarithms and trigonometry.The third chapter focuses on the astronomical triangle, which is a fundamental concept in astronomy that involves the relationship between the observer, a celestial object, and the center of the Earth. The chapter provides a detailed analysis of the various components of the triangle and their significance in determining azimuth.The fourth chapter explores the effect of errors in data on azimuth calculations. This includes a discussion of the sources of error, such as atmospheric refraction and instrument error, and the methods used to correct for these errors.Throughout the book, Craig provides numerous examples and illustrations to help readers understand the concepts and calculations involved in determining azimuth. The book also includes a glossary of terms and a detailed index for easy reference.Overall, Azimuth is a valuable resource for anyone interested in astronomy or navigation, providing a thorough and detailed exploration of this important topic.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
