It is odd to see a "Criticism" section in an article on a mathematical concept! Currently, it reads:

"So-called fractal derivative is a simple change of variables (x'=xβ, t'=tα). In addition, the authors make elementary mistakes, since does not take into account that it should be use (x>0, t>0) to consider fractional powers."

So ... no citation of who is making these criticisms, other than (most likely) the author of the section. Original research? NPOV? Pronouns? I think someone who is more knowledgeable should clean this up.168.156.98.245 (talk) 00:22, 14 May 2015 (UTC)[reply]

Porous media, aquifers, turbulence, and other media usually exhibit fractal properties.[edit]

Turbulence is not a porous medium. I do not want to just remove it because there is a way an expert might be able to work it in in such a way that it makes sense. 2A01:CB0C:CD:D800:C413:25AC:5081:8B7E (talk) 10:32, 4 April 2021 (UTC)[reply]
