 The universal period-tripling system has been discovered in various astronomical, geophysical, and biological phenomena in the range of periods from 1.64 billion years to 50 years; we then confirmed its existence on a scale of up to 10–15 seconds based on examples of human memory and hearing, several technical and medical devices, and, finally, in the settings of human and animal vision. This unprecedented multiscale discrete spectrum of periods has been studied thus far exclusively on the basis of literature data; as a result, it has been shown that many systems of a diverse nature, including the most common ones, operate against the background of a dimensionless spectrum of ~3k/2m periods. This is close to the spectrum of a stochastic attractor, which gives a Pythagorean musical octave. We confirm the result of this phenomenological generalization experimentally by testing various generators of electrical oscillations.
