Is this what a top mathematician looks like?
Is this what Mr. Witten meant when he said the knowledge in the top fields is interconnected?
Saierberg found it incredibly unbelievable, he was too embarrassed to interrupt, saying that he already couldn't understand some of it.
They are both students, but the gap is quite substantial!
...
The exchange on the second day didn't entirely convince Saierberg, but it made him realize 'how high the mathematical level of a mathematician capable of cracking the Goldbach Conjecture is'.
The obscure and difficult formulas, proofs, the other party completely understood after just listening once, some even were able to provide corrections, which made Edward fall into deep thought.
That is why Edward said, "Even if he doesn't understand string theory, it's important to have a dialogue with him." Saierberg now completely understood.
