Food Grade Mineral

Famous quotes containing the words food and/or grade:

    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)

    Ideas are like pizza dough, made to be tossed around, and nearly every book represents what my son’s third grade teacher refers to as a “teachable moment.”
    Anna Quindlen (b. 1952)
