Famous quotes containing the words cast and/or copies:
“The statue of Freedom has not been cast yet, the furnace is hot, we can all still burn our fingers.”
—Georg Büchner (1813–1837)
“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)
