A Shared Monument in the History of Physics and Mathematics!

At two o'clock that afternoon.

The venue was once again the auditorium on Jinling University's old campus.

Although attendance was down by a fifth from the day before, the atmosphere was still electric.

With the audience watching, Lu Zhou wrote on the blackboard as he explained the details of each step.

Whenever he filled a blackboard, staff quickly brought in another and lined the full one up neatly on the stage.

The staff came onstage five times, and six blackboards were filled.

When Lu Zhou wrote the final line—the general solution—the audience rose to their feet in excitement.

Thunderous applause swept from the front rows to the back like a wave, filling the hall in an instant.

Looking at the blackboards onstage, Edward Witten smiled as he applauded. "Good thing I didn't leave early. I would have missed a historic moment."

A faint smile appeared on Deligne's face too. With a trace of emotion, he said,

"Perhaps his talent in other areas of mathematics really is far greater than in algebraic geometry."

Hearing this, Fefferman joked, "Don't lose heart. Maybe he just hasn't taken an interest in algebraic geometry yet. Once he does, his results might astonish the entire field."

Deligne smiled without committing himself.

"I hope that day comes."

The applause gradually subsided.

It had surged in like a tide, and now it ebbed away just as swiftly.

As the audience sat back down, Lu Zhou set down his chalk.

He turned toward them, cleared his throat, and spoke slowly.

"We now have a general solution to the Yang–Mills Equations. It will also give us a deeper mathematical understanding of how microscopic particles interact, exist, and move."

"Next, I'll try to explain the Mass Gap in the Strong Interaction from a mathematical perspective."

At the startled murmurs from the
