There were once two physicists who propagated an Aryan physics and considered quantum mechanics as well as the theory of relativity incorrect because it was "Jewish". Both, the Austrian Philipp Lenard and the German Johannes Stark won a Nobel Prize in their younger years (1905 and 1919) and later developed their Aryan physics inspired by Nazi ideology. In the end, Aryan physics did not make any significant, consistent contribution to natural science, while quantum mechanics as well as relativity theory meant a great increase in knowledge. They were namely not Jewish, but correct.
Conclusion: The success of the natural science and physics does not lie in any assignments, but in their unconditional objectivity. This always aspired objectivity can be sometimes better and sometimes worse, however, it is certainly independent of any quality of the experimenter, discoverer, theory developer. And the requirement for physics is conceivably simple: it correctly predicts reality within the limits of previously defined validity (the reductionism that is always criticized but taken for granted).
