In the introduction to his book great astronomers, robert stawell ball states, “the history of astronomy thus becomes inseparable from the history of the great men to whose labours its development is due.” based on what you read in the ptolemy section, how does ball develop and refine this central idea in his book?

by providing biographical information about specific astronomers and their discoveries

Explanation:

Ball has written a book about the great astronomers and reveals that astronomy would not be what we know today without the lives of these men who have contributed so much to the development of this science.
