The heights by great men reached and kept
Were not attained by sudden flight,
But they, while their companions slept,
Were toiling upward in the night.
- H. W. Longfellow (The Ladder of St. Augustine)
From the mind of a nerdy chemical engineer
that feed on their viscosity,
and little whorls have lesser whorls
and so on to viscosity
-Lewis Richardson
