On the fourth day, the Gleize Civilization hosted another mathematics conference. Since Zhang Yuan himself was a mathematics expert and had not slackened in his studies over the years, he dutifully represented humanity at the conference.
All the presentations were very profound, and to Zhang Yuan's surprise, though he wouldn't comment on other disciplines, the mathematics of this civilization was indeed very impressive!
It might even surpass human mathematics!
In human society, there are many areas of mathematics that are still foundational, yet they had already been perfected and proven by the Gleize Civilization!
"Regarding your idea, I have a question. In our language, it's called the Hodge Conjecture..."
"Our current best approach is like this..."
After a discussion that lasted three hours, Zhang Yuan became increasingly excited, his old face flushed red.
