Famous quotes containing the word science:
“The so-called science of poll-taking is not a science at all but mere necromancy. People are unpredictable by nature, and although you can take a nation’s pulse, you can’t be sure that the nation hasn’t just run up a flight of stairs.”
—E.B. (Elwyn Brooks)
“After science comes sentiment.”
—Herman Melville (1819–1891)
