Famous quotes containing the words cast and/or copies:
“People who treat other people as less than human must not be surprised when the bread they have cast on the waters comes floating back to them, poisoned.”
—James Baldwin (1924–1987)
“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)
