A most comprehensive basis for studying astronomy
on 16 January 2013
This book is used as the basis of the course by at least two of the universities that offer distance learning courses. It has by far the most complete range of information about astronomy and all the related sciences that I've seen. The explanations are very clearly presented, using SI units as well as the astronomical quirks like AUs and parsecs. Though the 6th edition does omit the last 10 lively years in the subject, the basic parameters have not really changed. Though the CD was included with this used copy, I have not been able to make it work. Nevertheless, there are so many free sorces of information on the Web, that this scarcely matters. As promised, the copy I received was in brand-new condition.
