Association Scheme/the Bose-mesner Algebra

Famous quotes containing the words association, scheme and/or algebra:

    An association of men who will not quarrel with one another is a thing which has never yet existed, from the greatest confederacy of nations down to a town meeting or a vestry.
    Thomas Jefferson (1743–1826)

    I have no scheme about it,—no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?—and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?
    Henry David Thoreau (1817–1862)

    Poetry has become the higher algebra of metaphors.
    José Ortega Y Gasset (1883–1955)
