Famous quotes containing the words screens, optical and/or element:
“At length to hospital
This man was limited,
Where screens leant on the wall
And idle headphones hung.
Since he would soon be dead
They let his wife come along
And pour out tea, each day.”
—Philip Larkin (1922–1986)
“There is an optical illusion about every person we meet.”
—Ralph Waldo Emerson (1803–1882)
“Every American, to the last man, lays claim to a “sense” of humor and guards it as his most significant spiritual trait, yet rejects humor as a contaminating element wherever found. America is a nation of comics and comedians; nevertheless, humor has no stature and is accepted only after the death of the perpetrator.”
—E.B. (Elwyn Brooks)
