Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    It is not unkind to say, from the standpoint of scenery alone, that if many, and indeed most, of our American national parks were to be set down on the continent of Europe thousands of Americans would journey all the way across the ocean in order to see their beauties.
    Franklin D. Roosevelt (1882–1945)

    Freud was a hero. He descended to the “Underworld” and met there stark terrors. He carried with him his theory as a Medusa’s head which turned these terrors to stone.
    —R.D. (Ronald David)
