Famous quotes containing the words year and/or terms:
“In certain savage tribes in New Guinea, they put the old people up in the trees and shake them once a year in the spring; if they don’t fall out they let them live another year.”

“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)
