Fundamental astronomy Book

This book gives a well-balanced and comprehensive introduction to the various fields of classical and modern astronomy. Emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for deeper studies in the astronomical sciences. Using only simple mathematics, the book is an ideal introductory text for first- and second-year university students as well as for serious amateurs in the field. But the text has been arranged so that it can be understood without the mathematics, so the book should also be of interest to a wider audience.
