Diffeomorphism Group Acts

Famous quotes containing the words group and/or acts:

    He hung out of the window a long while looking up and down the street. The world’s second metropolis. In the brick houses and the dingy lamplight and the voices of a group of boys kidding and quarreling on the steps of a house opposite, in the regular firm tread of a policeman, he felt a marching like soldiers, like a sidewheeler going up the Hudson under the Palisades, like an election parade, through long streets towards something tall white full of colonnades and stately. Metropolis.
    John Dos Passos (1896–1970)

    A man’s real and deep feelings are surely those which he acts upon when challenged, not those which, mellow-eyed and soft-voiced, he spouts in easy times.
    Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 13 (1962)
