Pressure Waves

Famous quotes containing the words pressure and/or waves:

“We believe that civilization has been created under the pressure of the exigencies of life at the cost of satisfaction of the instincts.”

“You waves, though you dance by my feet like children at play,
Though you glow and you glance, though you purr and you dart;
In the Junes that were warmer than these are, the waves were more gay,
When I was a boy with never a crack in my heart.”
—William Butler Yeats (1865–1939)
