Khayyam on the finger

Omar Khayyám was an accomplished mathematician and an astronomer although he is most often remembered for Rubaiyat. That one line introduction out of way, let's get to the finger part. Khayyám wrote thusly,

"The Moving Finger writes, and, having writ,
Moves on: nor all thy Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all thy Tears wash out a Word of it."

We will all do well to remember that. Now, head over to Sunil's post on Khayyam, Galileo, fundies and the finger salute where he discusses much more and quotes from a recent article in Nature magazine.
