@tobyshooters Nice! Although, I think rather the system is derived from the experiment by engineers rather than from theory. E.g, the transistor: Quantum Physics + Electrodynamics (Theory) -> Early Patents and Bells Labs (Experiment) -> Common Topologies (System)

Note the twice Morse code XXX at the beginning of the transmission, indicating the highest priority.
