“When I heard the learn’d astronomer;     
When the proofs, the figures, were ranged in columns before me;
When I was shown the charts and the diagrams, to add, divide, and measure them;   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 wander’d off by myself,     
In the mystical moist night-air, and from time to time,     
Look’d up in perfect silence at the stars.

Walt Whitman When I heard the Learn’d Astronomer
