Reference Food

Famous quotes containing the words reference and/or food:

    Meaning is what essence becomes when it is divorced from the object of reference and wedded to the word.
    Willard Van Orman Quine (b. 1908)

    We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.
    Cyril Ponnamperuma (b. 1923)
