This is unscientific.
After a moment's thought, Robert Stephen said, "Is this just the opinion of our Huaxia colleagues? Forgive me for being blunt, but there are not many scholars in Huaxia who have made contributions to this issue…
Of course, I don't mean any disrespect to Professor Yang, but he has already reached a venerable age. So, I think everyone is simply under the illusion that they are because he gave the general solution to the Yang-Mills Equations. We all know that the proof of mass gap requires a more rigorous line of thought."
The reply came quickly from the handset: "That's exactly why I'm making this call. I've received an invitation to attend Qiao Ze's doctoral thesis defense and to listen to his thoughts. So, Robert, are you interested in joining me?"
Robert Stephen hesitated.
He had received an invitation to the last report meeting of Qiao Ze as well, but he chose not to attend.
