Elementary Equivalence/tarski-vaught Test

Famous quotes containing the words elementary and/or test:

    Listen. We converse as we live—by repeating, by combining and recombining a few elements over and over again just as nature does when of elementary particles it builds a world.
    William Gass (b. 1924)

    Unless the people can choose their leaders and rulers, and can revoke their choice at intervals long enough to test their measures by results, the government will be a tyranny exercised in the interests of whatever classes or castes or mobs or cliques have this choice.
    George Bernard Shaw (1856–1950)
