Silver/compounds

Famous quotes containing the words silver and/or compounds:

    ‘Guess now who holds thee?’—‘Death,’ I said. But,

    The silver answer rang, . . . ‘Not Death, but Love.’
    Elizabeth Barrett Browning (1806–1861)

    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)
