Closed Linear Span

Famous quotes containing the words closed and/or span:

    A closed mouth catches no flies.
    Miguel De Cervantes (1547–1616)

    School-days, I believe, are the unhappiest in the whole span of human existence. They are full of dull, unintelligible tasks, new and unpleasant ordinances, brutal violations of common sense and common decency. It doesn’t take a reasonably bright boy long to discover that most of what is rammed into him is nonsense, and that no one really cares very much whether he learns it or not.
    —H.L. (Henry Lewis)
