Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    The eyes that drew from me such fervent praise,
    The arms and hands and feet and countenance
    Which made me a stranger in my own romance
    And set me apart from the well-trodden ways;
    Petrarch (1304–1374)

    Don’t confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.
    Martin H. Fischer (1879–1962)
