Excerpt from A Compendium of Spherical Astronomy
The present volume is the first of a projected series having the double purpose of developing the elements of Practical and Theoretical Astronomy for the special student of the subject, and of serving as a handbook of convenient reference for the use of the working astronomer in applying methods and formulae. The plan of the series has been suggested by the author's experience as a teacher at the Johns Hopkins Uni versity, and as an investigator. The first has led him to the view that the wants of the student are best subserved by a quite elementary and condensed treatment of the subject, without any attempt to go far into details not admitting of immediate practical application. As an investigator he has frequently been impressed with the amount of time consumed in searching for the formulae and data, even of an elementary kind, which should be, in each case, best adapted to the work in hand.

The present volume is the first of a projected series having the double purpose of developing the elements of Practical and Theoretical Astronomy for the special student of the subject, and of serving as a handbook of convenient reference for the use of the working astronomer in applying methods and formulae.

The first has led him to the view that the wants of the student are best subserved by a quite elementary and condensed treatment of the subject, without any attempt to go far into details not admitting of immediate practical application. As an investigator he has frequently been impressed with the amount of time consumed in searching for the formulae and data, even of an elementary kind, which should be, in each case, best adapted to the work in hand. The most urgent want which the work is intended to supply is that of improved methods of deriving and reducing the positions and proper motions of the fixed stars. Modifications of the older methods are made necessary by the long period, 150 years, through which positions of the stars now have to be reduced, and by the extension of astrometrical and statistical researches to a great and constantly increasing number of telescopic stars.

Paperback. Etat : New. Print on Demand. This book presents a detailed and rigorous examination of techniques used in the field of spherical astronomy, focusing on the trigonometric reduction of star positions from one epoch to another. In astronomical work, stars are located by their geographic coordinates on the celestial sphere. These coordinates and the stars' motions are used to calculate time, date, and location on the Earth. Over time, these positions change so they need to be recalculated for every instance they are needed. The author begins with basic principles and works up to more advanced topics, explaining how calculations are done and the accuracy of results. This book combines historical context, technical explanations, and practical guidance for students and working astronomers seeking to advance their knowledge of astronomical coordinate systems, celestial measurements, and related concepts. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781330123669_0
