Plane Wave Spacetimes

Famous quotes containing the words plane and/or wave:

“Have you ever been up in your plane at night, alone, somewhere, 20,000 feet above the ocean?... Did you ever hear music up there?... It’s the music a man’s spirit sings to his heart, when the earth’s far away and there isn’t any more fear. It’s the high, fine, beautiful sound of an earth-bound creature who grew wings and flew up high and looked straight into the face of the future. And caught, just for an instant, the unbelievable vision of a free man in a free world.”
—Dalton Trumbo (1905–1976)

“I hear
the tide turning. Last
eager wave over-
taken and pulled back
by first wave of the ebb.”
—Denise Levertov (b. 1923)
