Famous quotes containing the words spectral and/or data:

    “How does one kill fear, I wonder? How do you shoot a spectre through the heart, slash off its spectral head, take it by its spectral throat?”
    —Joseph Conrad (1857–1924)

    “To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
    —F. Scott Fitzgerald (1896–1940)
