Thank you, Mister Logic.
Thank you! I try.
What’s really interesting to me is that there is no obvious contribution to the basics of mathematics, as we currently understand it internationally, from China.
The Chinese had a great deal of clever stuff. They had really sophisticated methods of numeric calculation for instance - the abacus ain’t half of it. They had their own takes on what we should call algebra, and way more advanced matters, some of it several centuries ahead of the rest of the world. They certainly could do the work.
But none of that seems to have leaked through to the international intellectual world, and we know of it now only through historical research.
