• First, to the issue of "toxic" fields. To everyone out there who wrote that the idea is nonsense, there are people who are still working on elementary-ish approaches to special cases of Fermat's Last Theorem. There could be good math there, but if all I knew about somebody was that he submitted an elementary proof that $x^{17}+y^{17}\not=z^{17}$, I would be disimpressed, and suspect crank-hood.
