Famous quotes containing the word science:
“Science in England, in America, is jealous of theory, hates the name of love and moral purpose. There’s revenge for this humanity. What manner of man does science make? The boy is not attracted. He says, I do not wish to be such a kind of man as my professor is.”
—Ralph Waldo Emerson (1803–1882)
“All science requires mathematics. The knowledge of mathematical things is almost innate in us.... This is the easiest of sciences, a fact which is obvious in that no one’s brain rejects it; for laymen and people who are utterly illiterate know how to count and reckon.”
—Roger Bacon (c. 1214–c. 1294)
