I think questions like this A mirror flips left and right, but not up and down (which is pure geometry) should be moved to Mathematics.
The reason this is not a good idea is because there is a lot of mathematical thinking which is done outside the mathematical community, because it has not acquired the proper rigorous embedding into standard axiomatic systems. Fluctuating quantum field theory is an example, but so is statistical theory of fields (like turbulence), mathematical topological models (like the topological field theories, which are easier to make mathematics because they have a smaller Hilbert space, but the embedding to mathematics is still not complete), and various cases where the best mathematical solution is not the most useful physical solution, for example, the flow of a fluid in a square duct.
The physics approach to mathematical problems is to make whatever approximations work best given the physical context, so an exact solution, like the exact solution of the quadratic equation, is often inferior to a linearized solution. The mathematics site looks to the answer which gives the most insight into the formal structure of the problem, not the answer which gives the most insight to the physical structure of the problem.
So I would even tolerate pure math questions where physicists and mathematicians disagree on the best answers, because the disagreements reflect a different point of view regarding what are the important aspects of a well posed mathematical problem.
