TO RICHARD CURTIS WITH THANKS

Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.

—NEWTON

How is it possible to account for the difference between past and future when an examination of the laws of physics reveals only the symmetry of time?… present-day physics makes no provision whatever for a flowing time, or for a moving present moment.

—P. C. W. DAVIES
The Physics of Time Asymmetry, 1974
