Simon Newcomb,
The Reminiscences of an Astronomer
“ At the time it had seemed intensely comical to see two enraged combatants—for so I amused myself by fancying them—hurling algebraic formulæ, of frightful complexity, at each other's heads. I did not then dream that I should live to be an object of the same sort of attack, and that from Hansen himself.To be revised, pulled to pieces, or superseded, as science advances, is the common fate of most astronomical work, even the best. It does not follow that it has been done in vain; if good, it forms a foundation on which others will build. ”
