  • (noun): A spatially constricted by concentrated source (especially of radiation or pollution).

Famous quotes containing the words source and/or point:

    If, for instance, they have heard something from the postman, they attribute it to “a semi-official statement”; if they have fallen into conversation with a stranger at a bar, they can conscientiously describe him as “a source that has hitherto proved unimpeachable.” It is only when the journalist is reporting a whim of his own, and one to which he attaches minor importance, that he defines it as the opinion of “well-informed circles.”
    Evelyn Waugh (1903–1966)

    I laugh when I think that all of Rome made it a point not to pronounce Drusilla’s name. Because Rome was mistaken for all those years. Love is not enough for me, and I understood that then.... To love someone is to accept to grow old with her. An old Drusilla is far worse than a dead one.
    Albert Camus (1913–1960)
