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.”

“With these I would be.
And with water: the waves coming forward, without cessation,
The waves, altered by sand-bars, beds of kelp, miscellaneous
driftwood,
Topped by cross-winds, tugged at by sinuous undercurrents
The tide rustling in, sliding between the ridges of stone,
The tongues of water, creeping in, quietly.”
—Theodore Roethke (1908–1963)
