Famous quotes containing the words fragrant and/or compounds:

“The City is of Night; perchance of Death,
But certainly of Night; for never there
Can come the lucid morning’s fragrant breath
After the dewy dawning’s cold grey air;”
—James Thomson (1834–1882)

“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)
