  The Persistence of Memory - S. Dali "Do we exist in time, or does time exist in us? (...) We conventionally think of time as something simple and fundamental that flows uniformly, independently from everything else, from the past to the future, measured by clocks and watches.

One after another, the characteristic features of time have proved to be approximations, mistakes determined by our perspective, just like the flatness of the Earth or the revolving of the sun. (...) What we call 'time' is a complex collection of structures, of layers." - Carlo Rovelli, The Order of Time
