About Han Geurdes
My expertise is twofold. In this particular case, my knowledge of statistical methodology counts. But of course one must have knowledge of quantum mechanics as well.
I never fully agreed with the "Einstein is wrong approach " of the nineties and early 2000. Together with Dr Nagata and Dr Nakamura I published work that showed in a very round about way that something could be wrong with the "Einstein is wrong " approach.
Other papers are, a.o. https://doi.org/10.1016/j.nexres.2025.101268. This paper shows that Einstein's idea about field theory of hidden variables might very well be correct. Another paper is about the Krein-Milman theorem from measure theory that questions the completeness of Bell's formula; https://ijqf.org/archives/7960
I am a pensioner. I earned my PhD in statistical methodology in 1992. The association with GDS Applied Mathematics BV is more like a consultant.
Because being a pensioner I could indulge myself also with foundations of mathematics. I think this paper https://rdcu.be/ewfW0 is interesting as well.
