That hand had slender fingers, the tips as pale and clear as if they had gathered a faint light, like transparent coagulated fat.
But what caught He Xun's attention was not the hand, but the problem on the piece of paper.
One of the world's seven great mathematical problems.
The Riemann hypothesis.
Proposed in 1859, it wasn't until over a century later, in 2016, that a mathematician proved this conjecture.
This kind of top-tier problem was a compulsory project at Norton University.
But He Xun noticed that the owner of the hand used a different method to prove the Riemann hypothesis than the one used by the mathematician in 2016.
His expression changed, and he finally got serious.
It was He Xun's first encounter with live streaming, and he had not turned off the barrage of comments.
Words of various colors floated by.
[Great God, can you teach college physics today?]
