Neil deGrasse Tyson's favorite quote is taped to the wall of his office - a 14th-century Persian poem called The Conference of the Birds. The original quote reads: "On choos**in**g a path to knowledge: A bird is not fully alive until he know**s** and indef**in**ighted Jour**ne**y." This tapestry is copied from a version of the poem that ador**nes** the wall of Ty**son**'s, now ex-wife, Alan**aye**'s of**fice** in**Ga**r**d**en**C**ity.
