When I heard the learned astronomer

"When I heard the learned astronomer,
When the proofs, the figures, were arranged in columns before me,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wandered off by myself,
In the mystical moist night-air, and from time to time,
Looked up in perfect silence at the stars"

... Walt Whitman
