Famous quotes containing the words bitter and/or compounds:
“I had this thought a while ago,
My darling cannot understand

In this blind bitter land.
And I grew weary of the sun”

“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 thats the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
