“ The stage on which all actions in the universe take place is space-time. Usually consisting of four dimensions (three for space and one for time) , space-time will be represented here in two dimensions—one for space, in the horizontal dimension, and one for time, in the vertical. ”
Richard Feynman, QED: The Strange Theory of Light and Matter (1985). copy citation
