Beschreibung

The first edition of this very successful book was a winner of the Astronomical Society of the Pacific's "Astronomy Book of the Year" award in 1986. The popularity of the book's programs is based on the ease with which the amateur astronomer can perform calculations on a personal computer. The routines are not specific to any make of computer and are user-oriented in that they utilize a simple version of the BASIC programming language and require only a broad understanding of any particular problem. Seven new subroutines in this new edition can be linked in any combination with the existing twenty-six. Since the programs themselves take care of details, they can be used, for example, to calculate the time of rising of any of the planets in any part of the world at any time in the future or past, or they may be used to find the circumference of the next solar eclipse visible from a particular place. In fact, almost every problem likely to be encountered by the amateur astronomer can be solved by a suitable combination of the routines given in this book. Peter Duffett-Smith is the author of another popular astronomy book: Astronomy with Your Calculator (3rd Edition), also published by Cambridge University Press.

Pressestimmen

"This is a work which all amateur astronomers will want to possess." Times Higher Education Supplement "This is one of the best publications of its type on the market today. The book is well written and illustrated. It is highly recommended." Journal of the Association of Lunar and Planetary Observers "...an example of how wonderful a tool a computer and a few programs can be. With the subroutines in this book, the amateur astronomer can have more time to concentrate on the heavens and leave the earthly work of astronomical computations to the computer...a good sourcebook for those amateur astronomers who are not afraid of some simple programming or for getting someone who is familiar with programming interested in astronomy. It could be useful to those who want more accuracy in their space games." William H. MacIntosh, Computing Reviews
