I consider race something absolutely objective and any reasonable racial classification purely biological. Technology and science are culture-neutral in the sense of almost everyone adapting the secular Western version of it, even those in Japan.
"Secular Western version of it" Western technics are superior to non-Western technics, so other cultures have appropriated them. You concede that a secular Western version of science does exist, so you concede my point that science is a product of Culture. Cultures can appropriate the belief systems, languages, and elements of technics and sciences from others but it is impossible for any action to be taken nor any thought contemplated independent of culture, the same way it is impossible to act independently of the self. Traditional sciences like acupuncture still exist and various sciences that have survived Western rationalism.
People must feel that their papers and math are leading somewhere
. It's their purpose in life to rationalize everything, it becomes a form of asceticism. One achieves greatness by rationalizing. This is your modality whether you realize it or not. The human mind can only process positives. Hence every action is given significance, but yours is profane and secular.
I assume that you mean "without ethnic culture"
I mean materialism and secular nihilism.
Please explain how math done by a Russian inherently differs from math done by a German or an Indian when people who read and write the papers couldn't care less about the biological and cultural background of the authors.
Western mathematics have been standardized, but they are only organically Western, else appropriated. Every culture has a unique (or lack thereof) theoretical mathematics, which has nothing to do with practicality. You find mostly Jews pioneering modern theoretical physics, and Europeans pioneering modern applied physics and engineering.
Follow evidence wherever it leads. If biology shows that there are multiple species of modern humans, so be it. If biology shows that there is only one species of homo sapiens, so be it. If science shows that genetic variation among humans is minor, so be it. If science shows that genetic variation among humans is major, so be it.
Don't assume science is so objective. It changes rapidly. In 500 years it's unlikely any major scientific theory today will be taught dogmatically. Rationalism always fails to provide a full explanation of anything, even the physical world - the observation of phenomenon cannot explain
