    Hello Philip,

    and thank you for the very interesting article, saved and sent to my old friends.

    Without having been much aware of it, I have been lucky to participate in my former life both in the research of applications of the QM, and later in the research of turbulence.
    Especially the turbulence at very high Reynolds numbers has been a pretty fascinating subject.

    Best,

    JG

    It's a wonderful article, especially in covering Heisenberg's contributions.

    For the sake of completeness I think it fair to mention Kolmogorov's contribution in 1941.

    https://en.wikipedia.org/wiki/Turbulence#Kolmogorov's_theory_of_1941

    https://en.wikipedia.org/wiki/Andrey_Kolmogorov

    I especially like the final paragraph.

    Occasionally, we hear about the “end of physics”—the idea that we are approaching the stage where all the important questions will be answered, and we will have a theory of everything. But from another point of view, the fact that such a commonplace phenomenon as the flow of water through a pipe is still in many ways an unsolved problem means that we are unlikely to ever reach a point that all physicists will agree is the end of their discipline. There remains enough mystery in the everyday world around us to keep physicists busy far into the future.

    Thank you not_Fritz for the comments and links.

    It is the spectral power exponent of -5/3 on the tail of the high k values in the Kolmogorov's model of turbulence,
    which has allowed to test his model against the other hypotheses.

    It happens seldom, that a model can be so straightforward verified,
