Famous quotes containing the words flexible, mold and/or compounds:
“Freedom is the essence of this faith. It has for its object simply to make men good and wise. Its institutions then should be as flexible as the wants of men. That form out of which the life and suitableness have departed should be as worthless in its eyes as the dead leaves that are falling around us.”
—Ralph Waldo Emerson (1803–1882)
“Unfortunately, life may sometimes seem unfair to middle children, some of whom feel like an afterthought to a brilliant older sibling and unable to captivate the family’s attention like the darling baby. Yet the middle position offers great training for the real world of lowered expectations, negotiation, and compromise. Middle children who often must break the mold set by an older sibling may thereby learn to challenge family values and seek their own identity.”
—Marianne E. Neifert (20th century)
“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)
