Famous quotes containing the words mathematics and/or science:
“Why does man freeze to death trying to reach the North Pole? Why does man drive himself to suffer the steam and heat of the Amazon? Why does he stagger his mind with the mathematics of the sky? Once the question mark has arisen in the human brain the answer must be found, if it takes a hundred years. A thousand years.”
—Walter Reisch (1903–1963)
“You are all fundamentalists with a top dressing of science. That is why you are the stupidest of conservatives and reactionists in politics and the most bigoted of obstructionists in science itself. When it comes to getting a move on you are all of the same opinion: stop it, flog it, hang it, dynamite it, stamp it out.”
—George Bernard Shaw (1856–1950)
