Order

Order is an asymmetric, or directed relation. It is such an important construct, it has been the essential building block for any computable programs[1], since Dana Scott considers that all data types are Partially ordered sets. It is also the basis of physical time, as articulated by Leslie Lamport in his famous paper:Time, Clocks, and the Ordering of Events in a Distributed System[2]. Ordering as a physical phenomenon, has a lot to do with spacetime. It would be particularly relevant to cite Hermann Minkowski:
The following quote appeared in Spacetime Physics[3], on page 15:
Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a union of the two will preserve an independent reality.
— Hermann Minkowski, 1864-1909
