Famous quotes containing the word food:
“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)
“At the violet hour, the evening hour that strives
Homeward, and brings the sailor home from sea,
The typist home at teatime, clears her breakfast, lights
Her stove, and lays out food in tins.”
—T.S. (Thomas Stearns)
“One farmer says to me, You cannot live on vegetable food solely, for it furnishes nothing to make bones with; and so he religiously devotes a part of his day to supplying his system with the raw material of bones; walking all the while he talks behind his oxen, which, with vegetable-made bones, jerk him and his lumbering plow along in spite of every obstacle.”
—Henry David Thoreau (18171862)
