Equivalence Class Structure

Famous quotes containing the words class and/or structure:

    A revolution is not a dinner party, or writing an essay, or painting a picture, or doing embroidery; it cannot be so refined, so leisurely and gentle, so temperate, kind, courteous, restrained and magnanimous. A revolution is an insurrection, an act of violence by which one class overthrows another.
    Mao Zedong (1893–1976)

    For the structure that we raise,
    Time is with materials filled;
    Our to-days and yesterdays
    Are the blocks with which we build.
    Henry Wadsworth Longfellow (1809–1882)
