Optical Activity

Famous quotes containing the words optical and/or activity:

    There is an optical illusion about every person we meet.
    Ralph Waldo Emerson (1803–1882)

    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)
