A sharply compressed handbook, this text, illustrated by Patricia Cullen, introduces the reader to the techniques and history of astronomy. Beginning with man's early devices for astronomical speculation--(Stonchenge, the pyramids)-- I.O. Evans proceeds in an orderly fashion integrating his study of astronomy with the lives and accomplishments of outstanding astronomers. Beside discussing current theories and plans for future research, considerable attention is given here to calculating instruments and the way they work. A highly readable and revealing book which will be an aid in or out of the classroom.
