If it’s not a joke, than what can I say – it’s an interesting observation (but for what?)

We show that some impassioned van Gogh paintings display scaling properties similar to the observed in turbulent fluids, suggesting that these paintings reflect the fingerprint of turbulence with such a realism that is even consistent with the way that a mathematical model characterizes this phenomenon. Specifically, we show that the probability distribution function (PDF) of luminance fluctuations of points (pixels) separated by a distance R is consistent with the Kolmogorov scaling theory in turbulent fluids. We also show that the most turbulent paintings of van Gogh coincide with periods of prolonged psychotic agitation of this artist.The conjunction is like this: if you see eddies in this beautiful picture from NASA
Then you may start thinking about all kind of PDF analysis of everything (e.g. R) and find out maybe that van Gogh’s paintings, e.g. The Starry Night is also “turbulent” in Kolmogorov (see the previous post) sense, isn’t it nice?

quote of the day
“A child becomes an adult when he realizes that he has a right not only to be right but also to be wrong.”
– Thomas Szasz
is it true in the case of a scientist? let’s try:
“A Ph.D. candidate becomes an scientist when he realizes that he has a right not only to be right but also to be wrong.”
what do you think?
