Algebraically Closed Fields

Famous quotes containing the words closed and/or fields:

    We are closed in, and the key is turned
    On our uncertainty;
    William Butler Yeats (1865–1939)

    Or seen the furrows shine but late upturned,
    And where the fieldfare followed in the rear,
    When all the fields around lay bound and hoar
    Beneath a thick integument of snow.
    So by God’s cheap economy made rich
    To go upon my winter’s task again.
    Henry David Thoreau (1817–1862)
