An Introduction to Astronomy
by Forest Ray Moulton
Publisher: The MacMillan Company 1916
Number of pages: 577
The aim has been to present the great subject of astronomy so that it can be easily comprehended even by a person who has not had extensive scientific training. It has been assumed that the reader has no intention of becoming an astronomer, but that he has an interest in the wonderful universe which surrounds him, and that he has arrived at such a stage of intellectual development that he demands the reasons for whatever conclusions he is asked to accept.
