Quantitative Structure Activity

Famous quotes containing the words structure and/or activity:

    Each structure and institution here was so primitive that you could at once refer it to its source; but our buildings commonly suggest neither their origin nor their purpose.
    Henry David Thoreau (1817–1862)

    The superstition respecting power and office is going to the ground. The stream of human affairs flows its own way, and is very little affected by the activity of legislators. What great masses of men wish done, will be done; and they do not wish it for a freak, but because it is their state and natural end.
    Ralph Waldo Emerson (1803–1882)
