 He denied not having one.  Most of the time, people don't outright lie
on Usenet.  They twist and turn, answering direct questiongs evasively
and inadequately, and assert half truths.
 My working theory at the moment is that WM has some university degree
which had a small component of mathematics, but that part of his degree
didn't cover rigorous analysis or rigorous set theory, or anything much
else rigorous.

"Von 1973 bis 1977 studierte Mückenheim Physik mit den Nebenfächern Mathematik, Astronomie und Chemie an der Georg-August-Universität Göttingen. Sein Diplomstudium schloss er bei Martin Schumacher mit einer Diplomarbeit über das kernphysikalische Thema Der Zerfall des 122J ab. 1979 erwarb er in der gleichen Göttinger Arbeitsgruppe den Doktorgrad im Fach Physik mit einer Dissertation über elastische Photonstreuung an Uran, einem Thema aus dem Gebiet der Vakuumpolarisation." (Wikipedia)
[From 1973 to 1977, Mückenheim studied physics with minors in mathematics, astronomy, and chemistry at the Georg August University of Göttingen. He completed his studies under Martin Schumacher with a thesis on the nuclear physics topic of "The Decay of 122J." In 1979, he earned his doctorate in physics in the same Göttingen research group with a dissertation on elastic photon scattering by uranium, a topic in the field of vacuum polarization.]
So he studied _4 years_ "physics with minors in mathematics, astronomy, and chemistry", go figure!
He clearly lacks a proper foundation in math.
