Famous quotes containing the words large, numbers, everyday and/or world:

    “... nothing seems completely to differentiate the poor but poverty. We find no adjectives to fit them, as a whole, only those of which Want is the mother. “Miserable” covers many; “shabby” most, and I am sadly aware that, in a large majority of minds, “disagreeable” includes them all.”
    —Albion Fellows Bacon (1865–1933)

    “Publishers are notoriously slothful about numbers, unless they’re attached to dollar signs—unlike journalists, quarterbacks, and felony criminal defendents who tend to be keenly aware of numbers at all times.”
    —Hunter S. Thompson (b. 1939)

    “Towns are full of people, houses full of tenants, hotels full of guests, trains full of travelers, cafés full of customers, parks full of promenaders, consulting-rooms of famous doctors full of patients, theatres full of spectators, and beaches full of bathers. What previously was, in general, no problem, now begins to be an everyday one, namely, to find room.”
    —José Ortega Y Gasset (1883–1955)

    “The idea that information can be stored in a changing world without an overwhelming depreciation of its value is false. It is scarcely less false than the more plausible claim that after a war we may take our existing weapons, fill their barrels with cylinder oil, and coat their outsides with sprayed rubber film, and let them statically await the next emergency.”
    —Norbert Wiener (1894–1964)
