Famous quotes containing the words reaction and/or wheel:
“Sole and self-commanded works,
Fears not undermining days,
Grows by decays,
And, by the famous might that lurks
In reaction and recoil,
Makes flames to freeze, and ice to boil.”
—Ralph Waldo Emerson (1803–1882)
“The wheel of fortune guide you,
The boy with the bow beside you
Run aye in the way
Till the bird of day
And the luckier lot betide you.”
—Ben Jonson (1572–1637)
