comment Self-Adjointness for Banach Spaces
At least the approach with the duality mapping specializes to the Hilbert space case…

comment Why distributions as functionals?
Although closed: There is a fundamental physical motivation for distributions which is nearly explained in Strichartz book "A Guide to Distribution Theory and Fourier Transforms", chapter 1. In a nutshell: If $f$ shall represent a physical quantity (like temparature, pressure,…) then it does not seem plausible from a physical point of view to talk about values of $f$ and some point $x$ because true point measurements are not possible. However, averaged measurements are possible and this gives rise to testing the quantity against functions and there you are.

comment Otelbayev's approach to Navier-Stokes
Well, it seems pretty hard to find the right words as a non-native… I added the reference to the journal as an additional piece of information and nothing more. I also see some red flags but but basically I hoped that somebody fluent in Russian and PDE/fluid dynamics would jump in and say something like "on page X there is this well known error" or "this step over there seems new"… But anyway, if the consensus is that questions like this are not appropriate, feel free to close.

comment Otelbayev's approach to Navier-Stokes
@MarianoSuárez-Alvarez Granted… But actually the english translation is not very far yet and ends before analysis starts. The introduction seems to be ok in that it cites relevant literature. I just added the respective remark to i) draw attention to the translation project and ii) to indicate that it is not obviously nonsense.

comment Examples of common false beliefs in mathematics
Well, although similar to Craig's answer on an open neighborhood of $\mathbb{Q}$ with arbitrarily small measure, I find this formulation much more appealing.

comment Polynomials with prescribed points to match prescribed bounds
That looks very interesting! Christmas time prevents that I check the answer in detail right now and since I am not sure, if I am going to come back here in due time I check this answer as correct right now to cash the bounty. Maybe I'll come back with questions later.
