Decoherence and the establishment of physical phenomena

We show, using various examples, that the decoherence and " physicalization " of an unencountered-before phenomena proceeds through the same stages of computer simulation and that one may use the known procedure of the latter in order to learn about the former. We use the example of programming and webmastering Internet websites that refer to known physical phenomena such as the harmonic oscillator and the energy shift (known from quantum field theory). We also discuss the classical cylinder and pistons used to measure entropy in classical thermodynamics.
