Proton Motive Force

Famous quotes containing the words motive and/or force:

“This part of being a man, changing the way we parent, happens only when we want it to. It changes because we are determined for it to change; and the motive for changing often comes out of wanting to be the kind of parent we didn’t have.”
—Augustus Y. Napier (20th century)

“Who shall set a limit to the influence of a human being? There are men, who, by their sympathetic attractions, carry nations with them, and lead the activity of the human race. And if there be such a tie, that, wherever the mind of man goes, nature will accompany him, perhaps there are men whose magnetisms are of that force to draw material and elemental powers, and, where they appear, immense instrumentalities organize around them.”
—Ralph Waldo Emerson (1803–1882)
