If anyone in the physics world walked past here, they would instantly recognize these two and ask for their signatures.
Unfortunately, the probability of someone recognizing them was less than one in a thousand.
Even though the ILHCRC headquarters in Shanghai would hold their first High Energy Physics Research Summit in a few days, that probability wouldn't increase by much.

Sitting next to Witten was Frank Wilczek, who was also going to the conference in Shanghai. Wilczek glanced at the journal in Witten's hand and squinted.
