Re: Quote of the day, mostly related to astronomy.
And a person of delicate ear and nice judgment discussed the singing at length, and showed how and wherein one star differed from another, and which was great and which was not.
And still the morning stars sang together.

Re: Quote of the day, mostly related to astronomy.
In the light of knowledge attained, the happy achievement seems almost a matter of course, and any intelligent student can grasp it without too much trouble. But the years of anxious searching in the dark, with their intense longing, their alternations of confidence and exhaustion and the final emergence into the light—only those who have experienced it can understand it.

But the two sciences have this in common, that to both are granted a magnificence of outlook, and an immensity of grasp denied to all the rest.
