Famous quotes containing the words bulbs and/or incandescent:

    The wide wonder of Broadway is disconsolate in the daytime; but gaudily glorious at night, with a milling crowd filling sidewalk and roadway, silent, going up, going down, between upstanding banks of brilliant lights, each building braided and embossed with glowing, many-coloured bulbs of man-rayed luminance. A glowing valley of the shadow of life. The strolling crowd went slowly by through the kinematically divine thoroughfare of New York.
    Sean O’Casey (1884–1964)

    Don’t think of yourself as an intestinal tract and tangle of nerves in the skull, that will not work unless you drink coffee. Think of yourself as incandescent power, illuminated perhaps and forever talked to by God and his messengers.... Think if Tiffany’s made a mosquito, how wonderful we would think it was!
    Brenda Ueland (1891–1985)
