Long Exact Sequence

Famous quotes containing the words long, exact and/or sequence:

    I can forgive even that wrong of wrongs,
    Those undreamt accidents that have made me
    Seeing that Fame has perished this long while,
    Being but a part of ancient ceremony
    Notorious, till all my priceless things
    Are but a post the passing dogs defile.
    William Butler Yeats (1865–1939)

    If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.
    William York Tindall (1903–1981)

    Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.
    Walter Benjamin (1892–1940)
