Famous quotes containing the words optical and/or waves:
“People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations.”
—Alexander Herzen (1812–1870)
“O beautiful for spacious skies,
For amber waves of grain,
For purple mountain majesties
Above the fruited plain!”
—Katharine Lee Bates (1859–1929)
