Famous quotes containing the word speed:
“For myself and my loved ones, I want the heat, which comes at the speed of light. I don’t want to have to hang about for the blast, which idles along at the speed of sound.”
—Martin Amis (b. 1949)
“There was such speed in her little body,
And such lightness in her footfall,
It is no wonder her brown study
Astonishes us all.”
—John Crowe Ransom (1888–1974)
“The correct rate of speed in innovating changes in long-standing social customs has not yet been determined by even the most expert of the experts. Personally I am beginning to think there is more danger in lagging than in speeding up cultural change to keep pace with mechanical change.”
—Mary Barnett Gilson (1877–?)
