IS THE AIRSHIP COMING? THAT depends, first of all, on whether we are to make the requisite scientific discoveries.

Star Gazing – A Cure for Tired Minds
The greatest spectacle offered man is a view of the magnificent vault of heaven. Under the stupendous arch of the Milky Way the cares of the world roll off.

Simon Newcomb – Born March 12, 1835, professor of mathematics in the United States Navy & Johns Hopkins University, retired Rear Admiral in 1897.

Newcomb primary focus was the explanation of the observed movements of the heavenly bodies

The reader who desires to approach this subject [the extent of the universe] in the most receptive spirit should begin his study by betaking himself on a clear, moonless evening, when he has no earthly concern to disturb the serenity of his thoughts, to some point where he can lie on his back on benh or roof and scan the whole vault of heaven at one view.

Studying the stars will cause “all human affairs to sink into insignificance

How is it possible through observation to learn about the universe as a whole?

Assumption that the Milky Way is the foundation or core structure of the universe

Assumption of even distribution of stars

/ˈperəˌlaks/

“what you see in the viewfinder won’t be quite what you get in the photograph because of parallax error”
the angular amount of parallax in a particular case, especially that of a star viewed from different points in the earth’s orbit.
plural noun: parallaxes
“he succeeded in measuring the parallax of the star 61 Cygni”
