Famous quotes containing the words year and/or terms:
“And year by year the landscape grow
Familiar to the stranger’s child;”
—Alfred Tennyson (1809–1892)
“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)
