Sound Wave

Famous quotes containing the words sound and/or wave:

“Philosophy ... does not talk, but write, or, when it comes personally before an audience, lecture or read; and therefore it must be read to-morrow, or a thousand years hence. But the talker must naturally be attended to at once; he does not talk on without an audience; the winds do not long bear the sound of his voice.”
—Henry David Thoreau (1817–1862)

“Great Powers of falling wave and wind and windy fire,
With your harmonious choir
Encircle her I love and sing her into peace,
That my old care may cease....”
—William Butler Yeats (1865–1939)
